It’s not always the best idea to remain in the cloud; sometimes it’s better to get back on the ground. Many businesses jumped in to make the most of the public cloud without thinking of the increased costs and no added value in terms of performance.
But there is no value or convenience in it; are you getting what you paid for?
What Is Cloud Repatriation and Why It Matters
Cloud repatriation is when applications and data are moved from the public cloud to on-premises. It’s not a failure; it’s a prudent method of emerging out of the cloud, and what proven businesses are implementing to improve their IT systems.
Many companies shifted all workloads, without determining whether or not the workloads benefit from moving to the public cloud. There’s been a shift in the discussion, as the cost associated with it and the compliance issues have been steadily increasing over the past few years. When dependency on cloud results in risk rather than helps to mitigate risk, often the first step that’s raised is a detailed IT Risk Management and Assessment.
The Real Drivers Behind Data Center Repatriation
Unpredictable Cloud Costs
Actually, businesses with consistent and predictable workloads can save more over the long haul (3-5 years) by taking ownership of resources in the cloud than paying a recurring cloud subscription expense. Until you get your cloud bills, a cloud cost optimisation strategy is a simple concept.
Performance and Compliance Issues
Lower-latency applications can be better served by the local infrastructure. There are regulations like HIPAA and GDPR that make that more comfortable, and some enterprises are more comfortable with hardware that they can control. In a Cloud Security Audit, compliance issues are oftentimes discovered that, without the need for repatriation, can be very expensive to solve.
Vendor Lock-In Risk
It’s a strategic risk to have all your data on a single cloud platform. This is because the technology can be taken home, providing more control for the organisations over the technology.
Cloud Workload Migration Challenges to Plan
Restoring workloads isn’t reverting to moving workloads to the cloud. Key challenges include:
- While cloud native applications can have a big impact on on-prem, a considerable amount of rework may be required.
- Exports of large amounts of data from the cloud are slow and expensive.
- A security configuration may change a lot, depending on the environment.
- If migration is not well planned, there is an increased risk of downtime during cutover.
Before the workloads are moved, the Managed Cloud Operations team evaluates if the workload is safe to move, the order of the workloads to move, and the amount of risk mitigation that will be needed.
Creating a realistic On-Premise Infrastructure Migration Strategy
Workload Assessment
This doesn’t need to be recovered. Put the workloads into classes based on cost, performance, compliance needs, and how dependent they are on cloud – some stay in the cloud, some come back to on-premises, and some go hybrid.
Infrastructure Readiness
Before moving anything, assess server capacity, storage, network, and backup configurations. It’s essential to have reliable connectivity.
Migration Sequencing
Changes in workload should be incremental and start with the lowest risk workloads. Simply monitor each step of the performance and security. Develop the rollback process in stages.
Post-Migration Validation
The SLAs are then confirmed, and security is provided once the SLAs are returned. Both on-prem and cloud can be monitored and alerted via AIOps and IT Automation.
The best way to do it via Hybrid Cloud
While most companies do not need to adopt an all-on-premise cloud solution, they are seeking to optimize their hybrid cloud. Run latency and/or compliance critical applications and data on premise or burst any load or data to the public cloud; it will restore the data during a disaster.
Secure Cloud Migration services that can be deployed in a hybrid architecture allow organizations to add the glue between on-prem and cloud in order to eliminate the security gaps that may occur as workloads move to the cloud. With AI workflow automation, this boosts efficiency, regardless of where workloads are stored.
When Repatriation Is Right?
If the costs of the cloud are too high compared to depreciation on premises, if SLAs for performance are not being met, or if it will be hard to meet compliance in public cloud, then it is reasonable to consider repatriation.
It’s not the best decision when applications are truly “cloud-native” or when the number of users scales up and down unpredictably, or when there isn’t an existing inside know-how to manage on-prem. It’s about information and not ideology – it’s about economics. Businesses that create a sincere cost model can make better infrastructure decisions more frequently.
