What are the types of cloud migration strategies?
In the realm of cloud migration, one size certainly does not fit all. Choosing the right strategy is paramount, and understanding the various approaches can be a game-changer. Here, we’ll explore the diverse types of cloud migration strategies.
Overview: The most straightforward migration strategy involves relocating VMware VMs from on-premises hardware to VMware Cloud on AWS (VMC). This can be achieved through reprovisioning from scratch, a cold migration, or a live migration.
Implications: This strategy is ideal for organizations seeking a fundamental shift without major modifications to their workloads. It offers simplicity and efficiency, making it suitable for various use cases.
2. Reprovisioning from Scratch
Overview: Though not strictly a migration, some workloads can be spun up as new instances in VMware Cloud on AWS. This approach involves bringing up new workloads in the cloud while retiring the old ones on-premises.
Implications: Suited for cattle workloads, this strategy provides a fresh start in the cloud. It’s an option worth considering for organizations looking to modernize without directly migrating existing instances.
3. Cold Migration strategy
Overview: In a cold migration, a workload is halted, moved to VMware Cloud on AWS, and then restarted. This method is suitable for non-production workloads where temporary downtime has minimal business impact.
Implications: Optimal for development or test workloads, a cold migration balances efficiency with minimal disruption. It’s a strategic choice when downtime can be managed without affecting critical operations.
4. Live Migration
Overview: Leveraging technologies like vMotion, live migration enables the movement of a running VM between on-premises environments and VMware Cloud on AWS. This feature is crucial for a hybrid cloud strategy.
Implications: As a near-essential for hybrid cloud adoption, live migration ensures continuous operations during the transition. It caters to organizations seeking a seamless shift without downtime.
Overview: Replatforming involves modifying or replacing components to better utilize cloud provider features. This may include switching to managed services or replacing commercial off-the-shelf software with open-source equivalents.
Implications: Organizations aiming to maximize cloud advantages opt for this strategy. It’s a shift beyond migration, focusing on optimizing workloads for enhanced performance and efficiency.
Overview: This strategy decommissions existing applications, replacing them with cloud-based versions from the provider’s marketplace. It’s a choice often made for on-premises ERP, finance, CRM, or HR applications.
Implications: Suited for legacy applications, repurchasing simplifies the transition by swapping one license fee for another. It streamlines operations by adopting readily available cloud-based solutions.
Overview: A complete re-architecting of applications to leverage unique cloud features. This may involve breaking up applications into smaller services, often deployed in a containerized environment on public clouds.
Implications: While a more expensive approach, refactoring delivers unparalleled benefits. It suits organizations aiming for cloud-native applications, emphasizing agility and scalability.
Overview: Not a migration per se, but retaining applications on existing on-premises infrastructure. This is common for critical applications running on legacy platforms, integrating with cloud-based resources through APIs.
Implications: Organizations with strong investments in existing infrastructure opt for this hybrid strategy, balancing the reliability of on-premises solutions with the advantages of cloud integration.
Overview: Every application has a lifecycle, and retiring involves decommissioning redundant applications. This step is taken when better options are available in cloud-based offerings.
Implications: A strategic move to streamline operations, retiring obsolete applications paves the way for more efficient and modern solutions.
