Azure Storage SAS Tokens
Azure Storage offers a robust set of data storage solutions including Blob Storage, Queue Storage, Table Storage, and Azure Files. A critical component of these services is the Shared Access Signature (SAS), a secure way to provide granular access to Azure Storage services. This article explores the intricacies of Azure Storage SAS Tokens.
Introduction to Azure Storage SAS Tokens
Azure Storage SAS tokens are essentially strings that allow access to Azure Storage services in a secure manner. They are a type of URI (Uniform Resource Identifier) that offer specific access rights to Azure Storage resources. They are a pivotal part of Azure Storage and are necessary for most tasks that require specific access permissions.
Types of SAS Tokens
There are different types of SAS tokens, each serving a specific function.
Service SAS
A Service SAS (Shared Access Signature) is a security token that grants limited access permissions to specific resources within a storage account. It is commonly used in Microsoft Azure’s storage services, such as Azure Blob Storage, Azure File Storage, and Azure Queue Storage.
A Service SAS allows you to delegate access to your storage resources to clients without sharing your account access keys. It is a secure way to control and restrict the operations that can be performed on your storage resources by specifying the allowed permissions, the time duration for which the token is valid, and the IP addresses or ranges from which the requests can originate.
By generating a Service SAS, you can provide temporary access to clients or applications, allowing them to perform specific actions like reading, writing, or deleting data within the specified resource. This approach helps enhance security by reducing the exposure of your storage account’s primary access keys.
Service SAS tokens can be generated using the Azure portal, Azure CLI (Command-Line Interface), Azure PowerShell, or programmatically using Azure Storage SDKs (Software Development Kits) in various programming languages.
It’s important to note that a Service SAS is different from an Account SAS. While a Service SAS grants access to a specific resource, an Account SAS provides access to multiple resources within a storage account.
Account SAS
An Account SAS (Shared Access Signature) is a security token that provides delegated access to multiple resources within a storage account. It is commonly used in Microsoft Azure’s storage services, such as Azure Blob Storage, Azure File Storage, and Azure Queue Storage.
Unlike a Service SAS, which grants access to specific resources, an Account SAS provides access at the storage account level. It allows you to delegate limited permissions to clients or applications to perform operations across multiple resources within the storage account, such as reading, writing, deleting, or listing blobs, files, or queues.
By generating an Account SAS, you can specify the allowed permissions, the time duration for which the token is valid, and the IP addresses or ranges from which the requests can originate. This allows you to control and restrict the actions that can be performed on the storage account’s resources, while still maintaining security by not sharing your account access keys.
Account SAS tokens can be generated using the Azure portal, Azure CLI (Command-Line Interface), Azure PowerShell, or programmatically using Azure Storage SDKs (Software Development Kits) in various programming languages.
It’s worth noting that an Account SAS has a wider scope than a Service SAS, as it provides access to multiple resources within the storage account. However, it also carries more responsibility since a compromised Account SAS token could potentially grant unauthorized access to all resources within the account.
Ad hoc SAS
Ad Hoc SAS (Shared Access Signature) refers to a dynamically generated SAS token that provides temporary and limited access to specific resources. Unlike a regular SAS token, which is typically created and configured in advance, an Ad Hoc SAS is generated on-demand and for a specific purpose.
The term “ad hoc” implies that the SAS token is created as needed, usually for short-term access requirements or specific scenarios where immediate access is necessary. It allows you to grant time-limited permissions to clients or applications for performing certain operations on designated resources within a storage account.
Ad Hoc SAS tokens can be generated using the appropriate APIs, SDKs, or command-line tools provided by the cloud storage service. When generating an Ad Hoc SAS, you specify the desired permissions, expiration duration, and optionally other restrictions such as IP addresses or protocol requirements.
The flexibility of Ad Hoc SAS tokens makes them particularly useful when you need to grant temporary access to resources without the need for long-term keys or complex authorization mechanisms. Once the token expires, the access granted by the SAS token is no longer valid, reducing the risk of unauthorized access.
Working of SAS Tokens
A SAS token works by appending a special set of query parameters to the URI that points to a storage resource. One of these parameters is a signature, created using the SAS parameters and signed with the key used to create the SAS. Azure Storage uses this signature to authorize access to the storage resource
SAS Signature and Authorization
In the context of Azure services, a SAS token refers to a Shared Access Signature token. SAS tokens are used to grant limited and time-limited access to specified resources or operations within an Azure service, such as storage accounts, blobs, queues, or event hubs.
When you generate a SAS token, you define the permissions and restrictions for the token, specifying what operations can be performed and the duration of the token’s validity. This allows you to grant temporary access to clients or applications without sharing your account’s primary access keys or credentials.
SAS tokens consist of a string of characters that include a signature, which is generated using your account’s access key and the specified permissions and restrictions. The token also includes other information like the start and expiry time of the token, the resource it provides access to, and any additional parameters you define.
By providing a client or application with a SAS token, you enable them to access the designated resources or perform specific operations within the authorized time frame. Once the token expires, the access is no longer valid, and the client or application would need a new token to access the resources again.
SAS tokens offer a secure and controlled way to delegate limited access to Azure resources, ensuring fine-grained access control and minimizing the exposure of sensitive account credentials.
What is a SAS Token
A SAS token is a string generated on the client side, often with one of the Azure Storage client libraries. It is not tracked by Azure Storage, and one can create an unlimited number of SAS tokens. When the client application provides the SAS URI to Azure Storage as part of a request, the service checks the SAS parameters and the signature to verify its validity
When to Use a SAS Token
SAS tokens are crucial when you need to provide secure access to resources in your storage account to a client who does not have permissions to those resources. They are commonly used in a scenario where usersread and write their own data to your storage account. In such cases, there are two typical design patterns:
- Clients upload and download data via a front-end proxy service, which performs authentication. While this allows for the validation of business rules, it can be expensive or difficult to scale, especially for large amounts of data or high-volume transactions.
- A lightweight service authenticates the client as needed and then generates a SAS. Once the client application receives the SAS, it can directly access storage account resources. The SAS defines the access permissions and the interval for which they are allowed, reducing the need for routing all data through the front-end proxy service.
A SAS is also required to authorize access to the source object in a copy operation in certain scenarios, such as when copying a blob to another blob that resides in a different storage account, or when copying a file to another file in a different storage account. You can also use a SAS to authorize access to the destination blob or file in these scenarios
Best Practices When Using SAS Tokens
Using shared access signatures in your applications comes with potential risks, such as the leakage of a SAS that can compromise your storage account, or the expiration of a SAS that may hinder your application’s functionality. Here are some best practices to mitigate these risks:
- Always use HTTPS to create or distribute a SAS to prevent interception and potential misuse.
- Use a User Delegation SAS when possible, as it provides superior security to a Service SAS or an Account SAS.
- Have a revocation plan in place for a SAS to respond quickly if a SAS is compromised.
- Configure a SAS expiration policy for the storage account to specify a recommended interval over which the SAS is valid.
- Create a Stored Access Policy for a Service SAS, which allows you to revoke permissions for a Service SAS without regenerating the storage account keys.
- Use near-term expiration times on an Ad hoc SAS, so even if a SAS is compromised, it’s valid only for a short time
Conclusion
In conclusion, Azure Storage SAS Tokens play a vital role in providing secure, granular access to Azure Storage services. Understanding the different types of SAS tokens, how they work, and best practices for their use is critical for managing access to your storage account resources effectively and securely.

The rapid technological advancements in the last decade led to a massive migration of data and applications from on-premise environments to the cloud. While this cloud migration trend dominated the IT world, a recent paradigm shift has emerged that’s moving in the opposite direction – ‘Cloud Reverse Migration’ or ‘Cloud Repatriation’. This burgeoning movement towards cloud repatriation has piqued the interest of many, prompting a need for a comprehensive exploration of this concept, its driving factors, and the tools that facilitate it.
Understanding Cloud Reverse Migration
Cloud Reverse Migration, also known as Cloud Repatriation, is the strategic move of transferring digital data, operations, applications, or services from a cloud environment back to its original on-premise location or to an alternate private data center. Contrary to some misconceptions, this migration process does not denote the failure of cloud computing; instead, it is a strategic response to the evolving needs of businesses and a reflection of the realization that not all workloads are suited for the cloud.
The Rising Trend of Cloud Repatriation
While the benefits of cloud computing – flexibility, scalability, and cost savings, to name a few – remain valid and significant, an increasing number of businesses are reconsidering their digital strategies and migrating their operations back on-premises. This trend, known as Cloud Repatriation, is becoming increasingly prevalent across different sectors for a multitude of reasons.
Reasons for Cloud Reverse Migration
Financial Considerations
At first glance, cloud services may appear to be a more cost-efficient alternative due to the reduced upfront costs and the promise of predictable recurring expenses. However, the reality is often more complicated. The ongoing costs of cloud services, which include data transfer fees and charges for additional services, can accumulate rapidly, turning what initially seemed like a cost-saving move into a financial burden. For some businesses, investing in and maintaining in-house infrastructure can be more cost-effective over the long term.
Data Security and Control
With data breaches and cyberattacks becoming more sophisticated and commonplace, organizations are increasingly concerned about their data’s security. While cloud service providers have robust security measures in place, storing sensitive data off-premises often results in companies feeling they have less control over their data protection strategies. By migrating data back on-premise, organizations can regain control and implement security measures tailored to their unique requirements.
Performance and Latency Issues
Despite the cloud’s advantages, certain applications, particularly those requiring real-time data processing and low latency, can face performance issues in a cloud environment. Factors such as network congestion, physical distance from the data center, and shared resources can result in slower response times. As such, for applications where speed is paramount, on-premises solutions often prove superior.
Compliance and Regulatory Concerns
Certain industries, such as healthcare and finance, are subject to strict data management regulations. These industries often need to keep their data on-premises to comply with data sovereignty laws and privacy regulations. In such cases, cloud reverse migration becomes a necessary step towards ensuring compliance and avoiding hefty penalties.

As we continue to journey through 2023, one of the highlights in the tech world has been the evolution of Azure Storage, Microsoft’s cloud storage solution. Azure Storage, known for its robustness and adaptability, has rolled out several exciting updates this year, each of them designed to enhance user experience, improve security, and provide more flexibility and control over data management.
Azure Storage has always been a cornerstone of the Microsoft Azure platform. The service provides a scalable, durable, and highly available storage infrastructure to meet the demands of businesses of all sizes. However, in the spirit of continuous improvement, Azure Storage has introduced new features and changes, setting new standards for cloud storage.
A New Era of Security with Azure Storage
A significant update this year has been the disabling of anonymous access and cross-tenant replication on new storage accounts by default. This change, set to roll out from August 2023, is an important step in bolstering the security posture of Azure Storage.
Traditionally, Azure Storage has allowed customers to configure anonymous access to storage accounts or containers. Although anonymous access to containers was already disabled by default to protect customer data, this new rollout means anonymous access to storage accounts will also be disabled by default. This change is a testament to Azure’s commitment to reducing the risk of data exfiltration.
Moreover, Azure Storage is disabling cross-tenant replication by default. This move is aimed at minimizing the possibility of data exfiltration due to unintentional or malicious replication of data when the right permissions are given to a user. It’s important to note that existing storage accounts are not impacted by this change. However, Microsoft highly recommends users to follow these best practices for security and disable anonymous access and cross tenant replication settings if these capabilities are not required for their scenarios.
Azure Files: More Power to You
Azure Files, a core component of Azure Storage, has also seen some significant updates. With a focus on redundancy, performance, and identity-based authentication, the changes bring more power and control to the users.
One of the exciting updates is the public preview of geo-redundant storage for large file shares. This feature significantly improves capacity and performance for standard SMB file shares when using geo-redundant storage (GRS) and geo-zone redundant storage (GZRS) options. This preview is available only for standard SMB Azure file shares and is expected to make data replication across regions more efficient.
Another noteworthy update is the introduction of a 99.99 percent SLA per file share for all Azure Files Premium shares. This SLA is available regardless of protocol (SMB, NFS, and REST) or redundancy type, meaning users can benefit from this SLA immediately, without any configuration changes or extra costs. If the availability drops below the guaranteed 99.99 percent uptime, users are eligible for service credits.
Microsoft has also rolled out Azure Active Directory support for Azure Files REST API with OAuth authentication in public preview. This update enables share-level read and write access to SMB Azure file shares for users, groups, and managed identities when accessing file share data through the REST API. This means that cloud native and modern applications that use REST APIs can utilize identity-based authentication and authorization to access file shares.
A significant addition to Azure Files is AD Kerberos authentication for Linux clients (SMB), which is now generally available. Azure Files customers can now use identity-based Kerberos authentication for Linux clients over SMB using either on-premises Active Directory Domain Services (AD DS) or Azure Active Directory Domain Services (Azure AD DS).
Also, Azure File Sync, a service that centralizes your organization’s file shares in Azure Files, is now a zone-redundant service. This update means thatan outage in a zone has limited impact while improving the service resiliency to minimize customer impact. To fully leverage this improvement, Microsoft recommends users to configure their storage accounts to use zone-redundant storage (ZRS) or geo-zone redundant storage (GZRS) replication.
Another feature that Azure Files has made generally available is Nconnect for NFS Azure file shares. Nconnect is a client-side Linux mount option that increases performance at scale by allowing you to use more TCP connections between the Linux client and the Azure Premium Files service for NFSv4.1. With nconnect, users can increase performance at scale using fewer client machines, ultimately reducing the total cost of ownership.
Azure Blob Storage: More Flexibility and Control
Azure Blob Storage has also seen significant updates in 2023, with one of the highlights being the public preview of dynamic blob containers. This feature offers customers the flexibility to customize container names in Blob storage. This may seem like a small change, but it’s an important one as it provides enhanced organization and alignment with various customer scenarios and preferences. By partitioning their data into different blob containers based on data characteristics, users can streamline their data management processes.
Azure Storage – More Powerful than Ever
The 2023 updates to Azure Storage have further solidified its position as a leading cloud storage solution. With a focus on security, performance, flexibility, and control, these updates represent a significant step forward in how businesses can leverage Azure Storage to meet their unique needs.
The disabling of anonymous access and cross-tenant replication by default is a clear sign of Azure’s commitment to security and data protection. Meanwhile, the updates to Azure Files, including the introduction of a 99.99 percent SLA, AD Kerberos authentication for Linux clients, Azure Active Directory support for Azure Files REST API with OAuth authentication, and the rollout of Azure File Sync as a zone-redundant service, illustrate Microsoft’s dedication to improving user experience and performance.
The introduction of dynamic blob containers in Azure Blob Storage is another example of how Azure is continually evolving to meet customer needs and preferences. By allowing users to customize their container names, Azure has given them more control over their data organization and management.
Overall, the updates to Azure Storage in 2023 are a testament to Microsoft’s commitment to continually enhance its cloud storage offerings. They show that Azure is not just responding to the changing needs of businesses and the broader tech landscape, but also proactively shaping the future of cloud storage. As we continue to navigate 2023, it’s exciting to see what further innovations Azure Storage will bring.

Your Key to Fortifying Data Storage and Accessibility in 2023
In the ever-evolving landscape of cloud computing, data redundancy is no longer just an option but a must-have feature for any business looking to fortify its data storage and accessibility. One of the most recent additions to the world of data redundancy is Azure Files’ Geo-Redundancy feature, a 2023 release that’s set to take the world of cloud storage by storm.
What is Azure Files Geo-Redundancy?
To understand Azure Files Geo-Redundancy, let’s first delve into the basics. Azure Files is a managed file share service provided by Microsoft Azure, offering secure and highly available network file shares accessible via the Server Message Block (SMB) protocol. Geo-Redundancy, on the other hand, refers to the replication of data across different geographical regions for the purpose of data protection and disaster recovery.
Azure Files Geo-Redundancy allows for multiple copies of your storage account data to be maintained, ensuring high durability and availability. If your primary region becomes unavailable for any reason, an account failover can be initiated to the secondary region, allowing for seamless business continuity.
GRS and GZRS: Enhancing Your Data Redundancy
Azure Files Geo-Redundancy offers two types of storage options, each with its unique advantages. Geo-Redundant Storage (GRS) makes three synchronous copies of your data within a single physical location in the primary region, and then makes an asynchronous copy to a single physical location in the secondary region. On the other hand, Geo-Zone-Redundant Storage (GZRS) copies your data synchronously across three Azure availability zones in the primary region before making an asynchronous copy to a physical location in the secondary region.
One important distinction to note is that Azure Files does not support read-access geo-redundant storage (RA-GRS) or read-access geo-zone-redundant storage (RA-GZRS). Consequently, the file shares won’t be accessible in the secondary region unless a failover occurs.
Boosting Performance and Capacity with Large File Shares
Another standout feature of Azure Files Geo-Redundancy is its ability to support large file shares. When enabled in conjunction with GRS and GZRS, the capacity per share can increase up to 100 TiB – a whopping 20 times increase from the previous limit of 5 TiB. Additionally, maximum IOPS per share can reach up to 20,000 IOPS, and the maximum throughput per share can reach up to 300 MiB/s. These enhancements significantly improve the performance of your file shares, making them more suitable for data-intensive applications and workloads
Where is Azure Files Geo-Redundancy Available?
As of 2023, Azure Files Geo-Redundancy for large file shares is available in a wide range of regions, including multiple locations in Australia, China, France, Germany, Japan, Korea, South Africa, Sweden, the United Arab Emirates, the United Kingdom, and the United States. This extensive coverage provides businesses with the flexibility to choose the most appropriate locations for their data storage based on their specific needs and compliance requirements
Getting Started with Azure Files Geo-Redundancy
Ready to fortify your data storage with Azure Files Geo-Redundancy? The registration process is simple and can be done via the Azure portal or PowerShell. Once you’re registered, you can easily enable geo-redundancy and large file shares for new and existing standard SMB file shares
The Snapshot and Sync Mechanism
To ensure consistency of file shares when a failover occurs, Azure creates a system snapshot in the primary region every 15 minutes, which is then replicated to the secondary region. The Last Sync Time (LST) property on the storage account indicates the last time data from the primary region was successfully written to the secondary region. However, due to potential geo-lag or other issues, the latest system snapshot in the secondary region might be older than 15 minutes. It’s also important to note that the Last Sync Time isn’t updated if no changes have been made on the storage account, and its calculation can time out if the number of file shares exceeds 100 per storage account
Considerations for Failover
When planning for a failover, there are a few key considerations to keep in mind. Firstly, a failover will be blocked if a system snapshot doesn’t exist in the secondary region. Secondly, file handles and leases aren’t retained on failover, requiring clients to unmount and remount the file shares. Lastly, the file share quota might change after failover as it’s based on the quota that was configured when the system snapshot was taken in the primary region
Practical Use Cases
Azure Files Geo-Redundancy offers myriad benefits that apply to various business scenarios. For organizations dealing with large datasets, the enhanced capacity and performance limits with large file shares can significantly improve their data management capabilities. Companies operating in multiple geographical locations can also benefit from the wide regional availability of the service, allowing them to maintain data proximity and potentially meet certain compliance and regulatory requirements.
Azure Files Geo-Redundancy is a promising new addition to the world of cloud storage, providing businesses with an effective tool to enhance their data redundancy and resilience. With its robust features and capabilities, it’s set to pave the way for more secure, reliable, and efficient data storage in the cloud.
So, whether you’re a small business looking to safeguard your data or a large enterprise aiming to optimize your data infrastructure, Azure Files Geo-Redundancy is a feature worth exploring. Its potential to enhance data storage, accessibility, and redundancy makes it a game-changing solution in the ever-evolving landscape of cloud computing.
Conclusion
Azure Files’ new geo-redundancy feature further enhances the utility of Cloud Storage Manager, a tool that can help users manage their Azure file shares efficiently and cost-effectively. As a fully managed cloud-native file sharing service, Azure Files is designed to be always on and accessible via the standard Server Message Block (SMB) protocol. However, native file share management is an area where it lacks. This is where Cloud Storage Manager shines, providing the necessary tools and interfaces to manage your Azure Files storage with ease. Thus, with the addition of geo-redundancy to Azure Files, Cloud Storage Manager becomes an even more invaluable tool in managing the increased complexity and unlocking the potential cost savings that come with larger, geo-redundant file shares.
In the digital era, data is a business’s most valuable asset. The ability to protect and access that data, especially during unexpected events, is critical. This is where Azure Files Geo-Redundancy shines, offering businesses a robust and flexible solution to secure their data and ensure its availability across different geographical regions.

Understanding Cloud Repatriation
In the modern digital age, the migration of data and applications to the cloud has been a significant trend, prompted by the promise of increased efficiency, scalability, and reduced IT costs. Cloud services such as Microsoft’s Azure Cloud have become increasingly popular, offering a host of services including computing power, storage solutions, and advanced analytics. But as with any technology, the cloud has its limitations, and businesses are beginning to realize that not all applications and workloads are suited to the cloud environment. This has given rise to a new trend – cloud repatriation.
Cloud repatriation, sometimes referred to as de-clouding, is the process of moving workloads and data back from the cloud to on-premise or local data centers. While it may seem counter-intuitive in the age of digital transformation, many businesses are finding it a necessary step to maintain control over their data, reduce costs, and overcome performance issues associated with the cloud. This process of migrating back to an on-premise environment from Azure Cloud is what we refer to as Azure Cloud Repatriation.
The concept of Cloud Repatriation
Cloud repatriation is not a new phenomenon but has gained significant attention recently. The initial appeal of the cloud was undeniable, with its promise of unlimited scalability, reduced hardware costs, and access to advanced technologies. However, as businesses dived into the cloud, certain issues began to surface. Some companies found their cloud expenditures spiraling out of control, while others discovered that their specific workloads didn’t perform as well in the cloud as they did on-premise. Then there were issues related to compliance and data sovereignty.
All these factors combined, led businesses to rethink their cloud strategies and consider the option of cloud repatriation. But why are businesses considering cloud repatriation, you might ask? Well, there are several factors at play here. Cost considerations, the need for greater control, security concerns, and performance issues are some of the leading drivers for businesses to move their workloads back on-premise. However, the process of repatriation is not straightforward.
There are several challenges that businesses need to overcome. It requires careful planning, selecting which workloads to move, preparing the on-premise environment, and actually moving the data and applications. It’s not just a simple case of ‘lifting and shifting’. It involves considerable time and resources and needs to be done in a manner that minimizes business disruption.
In the next few paragraphs, we will delve into the Azure Cloud, understand its benefits and common use cases, and why businesses might want to move away from it to an on-premise environment. We will then explore the process of Azure Cloud Repatriation and how businesses can simplify it with the help of Carbon, a software tool developed by SmiKar.

Benefits of Azure Cloud
One of the most significant benefits of Azure is its seamless integration with other Microsoft products, making it an ideal choice for organizations heavily invested in Microsoft technologies.
It also offers substantial cost savings by eliminating the need to invest in and maintain on-premise hardware. With its scalability, businesses can easily scale up or down their resources based on their needs, paying only for what they use. In terms of security, Azure provides robust security measures, with security analytics and threat intelligence built into the platform. It also offers tools for regulatory compliance, making it an attractive option for businesses in regulated industries.
Lastly, Azure’s global footprint with data centers worldwide allows businesses to deploy their applications close to their customers, reducing latency, and improving user experience.
Common use cases of Azure Cloud
Azure is often used for data backup and disaster recovery due to its reliability and robustness. It’s also commonly used for building, deploying, and managing applications and services, thanks to its PaaS offerings. Additionally, businesses use Azure for data analytics and artificial intelligence, utilizing its advanced capabilities to gain insights and make data-driven decisions. In many instances, Azure also supports the shift towards a remote work environment by providing a secure and scalable platform for virtual desktops and collaboration tools.

The need for control and security
One of the primary reasons for Azure repatriation is the need for more control over data and infrastructure. With Azure, while Microsoft takes care of the underlying infrastructure, businesses may feel they lack control over their environment. This can be a significant concern, especially for businesses in highly regulated industries or those dealing with sensitive data. On-premise environments provide businesses with complete control over their data, including where it’s stored, who can access it, and how it’s protected.
Similarly, while Azure provides robust security measures, some businesses might still prefer the security of having their data on-premise. This could be due to specific regulatory requirements or simply a preference for having physical control over their data.
Cost considerations
While cloud services offer the promise of reducing IT costs, the reality can be quite different. Depending on the usage pattern and the specific workloads, the costs of running services on Azure can quickly add up. These can include not just the costs of compute and storage, but also network costs, and the costs of other Azure services. For businesses with stable and predictable workloads, it might be more cost-effective to host these workloads on-premise, even when considering the costs of purchasing and maintaining hardware.
Performance and latency
While Azure’s global footprint allows businesses to deploy their applications close to their customers, there might still be performance issues or latency, especially for businesses serving a local or specific geographic market. In such cases, hosting the applications on-premise might provide a better user experience.
The Process of Azure Cloud Repatriation
The process of repatriating workloads from Azure Cloud to on-premise environments can be complex and requires careful planning.
Planning for Repatriation
Before initiating the repatriation process, businesses need to thoroughly evaluate their workloads and identify which ones would benefit from being on-premise. They need to consider the costs, performance requirements, and security and compliance requirements of these workloads.
Selecting VMs for Repatriation
Once the workloads have been identified, the next step is to select the Virtual Machines (VMs) on Azure that host these workloads. These VMs would need to be replicated and migrated back to the on-premise environment.
Preparing the on-premise environment
Finally, before the repatriation can begin, the on-premise environment needs to be prepared. This includes setting up the necessary hardware, configuring the network, and setting up the virtualization platform, whether it’s VMware or Hyper-V.
This process, while necessary, can be time-consuming and complex, especially for businesses with large numbers of VMs or complex applications. This is where Carbon, a software tool developed by SmiKar, can help.
