Cloud Repatriation

What is Cloud Repatriation?

Cloud repatriation, also known as cloud exit or cloud-to-on-premises migration, refers to the process of moving applications, data, or workloads from a cloud computing environment back to an on-premises infrastructure or a different cloud environment. In other words, it is the reversal of cloud adoption, where organizations move their resources from the cloud to an on-premises data center or to a different cloud provider. 

Why should enterprises consider cloud repatriation?

There can be several reasons why organizations may choose to repatriate their resources from the cloud, such as rising costs, data sovereignty concerns, security or compliance requirements, vendor lock-in, or performance issues. Repatriation may also occur as part of a larger strategy to optimize IT resources and balance workloads across different environments. 

What are the challenges associated with cloud repatriation?

There are many challenges with cloud repatriation, and most enterprises do not see cloud repatriation as a viable strategy for lowering cloud costs. Repatriation is often a complex and time-consuming process that requires careful planning, assessment, and execution to avoid disruption to business operations and data loss. Organizations need to consider factors such as migration tools, data transfer costs, network connectivity, infrastructure requirements, and data backup and recovery options when planning a cloud repatriation strategy.  

Also enterprises must consider the cost and complexity of migrating workloads back to an on-premises or alternative cloud environment, the need for skilled personnel to manage the infrastructure, and the potential loss of some of the benefits of cloud computing, such as scalability and elasticity. Therefore, organizations should carefully evaluate the benefits and drawbacks of repatriation before making a critical decision.

What steps should an enterprise take for cloud repatriation?

The adoption of cloud repatriation can vary widely depending on the specific needs and circumstances of each organization. First and foremost, organizations should deeply consider whether repatriation is a viable strategy or if there are other ways to achieve their objections while using the cloud.  However, there are some common steps and best practices that companies can follow to ensure a successful repatriation process: 

1. Evaluate the business case: Before starting the repatriation process, companies should carefully evaluate the business case for repatriation and determine the specific drivers and benefits for doing so. This assessment should include a review of the current cloud environment, costs, performance, compliance, and other factors. 

2. Create a migration plan: Once the decision to repatriate has been made, companies should develop a detailed migration plan that outlines the specific steps, timelines, resources, and budget required to complete the repatriation process. This plan should also include contingency plans in case of unexpected issues or delays. 

3. Decide the right infrastructure: Companies should identify the right infrastructure and hardware for their repatriation needs, which may include on-premises data centers, private clouds, or alternative public cloud providers. They should also consider factors such as security, compliance, performance, and scalability when selecting the infrastructure. 

4. Deliver the migration: The actual repatriation process involves migrating applications, data, and workloads from the existing cloud environment to the new on-premises or alternative cloud environment. This process can take weeks or even months, depending on the size and complexity of the environment. 

5. Validate and optimize: After the migration is complete, companies should test and optimize their new environment to ensure that it meets their performance, security, and compliance requirements. They should also establish processes for ongoing management and monitoring of the environment. 

How long does cloud repatriation take?

The timeline for cloud repatriation can vary depending on the specific circumstances of each organization. Some repatriation projects can be completed in a matter of weeks, while others may take several months or even years. The timeline can be influenced by factors such as the complexity of the environment, the amount of data to be migrated, the availability of skilled personnel, and the resources available for the project. Therefore, it is important for companies to carefully plan and execute their repatriation project to minimize disruption and achieve their desired outcomes. 

Who is responsible for cloud repatriation?

The responsibility for cloud repatriation typically lies with the organization that owns and operates the IT infrastructure and resources. Specific roles and responsibilities for cloud repatriation can vary depending on the size and complexity of the organization, as well as the nature of the repatriation project. Some common roles and responsibilities that may be involved in cloud repatriation include: 

1. Executive sponsor: The executive sponsor is responsible for overseeing the repatriation project, setting goals and priorities, securing resources and funding, and ensuring that the project aligns with the organization’s strategic objectives.  

2. Project managers: The project manager is responsible for leading the repatriation project, developing the project plan, coordinating resources and activities, and ensuring that the project is completed on time, within budget, and to the required quality standards.  

3. Technical leads: The technical lead is responsible for the technical aspects of the repatriation project, including infrastructure design, migration planning, data transfer, testing, and optimization.  

4. Operations team: The operations team is responsible for managing the day-to-day operations of the new on-premises or alternative cloud environment, including maintenance, monitoring, and support.  

5. Line of business stakeholders: Business stakeholders are responsible for ensuring that the repatriation project meets the needs and requirements of the business, including performance, security, compliance, and cost. 

Ultimately, the success of cloud repatriation depends on the collaboration and coordination of all stakeholders involved, as well as their ability to effectively plan, execute, and manage the repatriation project. 

What risks are involved with cloud repatriation?

Cloud repatriation can involve several common risks such as: 

• Data loss: The process of migrating data from the cloud back to an on-premises or alternative cloud environment can be complex and time-consuming, and there is a risk of data loss or corruption during the transfer. 
• Cost overage: Repatriation can be expensive, and organizations may encounter unexpected costs related to infrastructure, personnel, data transfer, or other factors that can lead to cost overruns.
• Enterprise disruption: Repatriation can cause disruption to business operations, especially if it involves critical workloads or applications. This can lead to lost revenue, decreased productivity, or damage to customer relationships. 
• Security vulnerability: Repatriation can introduce new security risks, such as vulnerabilities in the new infrastructure, increased exposure to cyberattacks, or inadequate security controls. 
• Compliance concerns: Repatriation can raise compliance issues, such as the need to comply with data protection regulations or industry standards in the new environment. 
• Lack of resources: Repatriation can require specialized skills and expertise that may not be available in-house. This can lead to delays, errors, or other issues that can impact the success of the repatriation project. 

How does Azul help with cloud repatriation?  

Due to the numerous challenges, lengthy times and risks explored above, cloud repatriation is not always in the best long-term interest of your enterprise. There are steps your company can take to mitigate cloud costs without leaving the cloud, including right-sizing resources and using a high-performance Java application runtime.  

Organizations might consider repatriation as a means of reducing cloud spending. However, repatriation is a risky proposition and vacates the benefits that drove an enterprise’s cloud adoption in the first place. Azul Platform Prime provides a powerful tool for companies to stay in the cloud, avoid the opportunity cost of repatriating workloads, while significantly reducing cloud spending. Azul Platform Prime delivers a simple formula: faster code = less compute = a smaller cloud bill. Rather than leaving the cloud, companies should simply optimize their cloud infrastructure through the use of a high-performance Java runtime such as Azul Platform Prime.
