Let us start with 50,000 ft view of what is Cloud Migration?
In simple words it is moving your IT systems (hardware, software) from on-premises infrastructure to cloud infrastructure.
Common jargon used are such as moving IT workloads, Digital Assets, Data etc. from on-premises infrastructure to cloud infrastructure.

Variation: If you are already in the cloud infrastructure, another variation could be moving IT workloads from one cloud vendor to another cloud vendor. Now if we go along the same lines, what is a cloud migration strategy?

Cloud Migration Strategy

A cloud migration strategy is the process an organization adopts to move existing on-premises IT workloads into the cloud.

With cloud services, companies can store and process their data in a flexible, scalable, and secure manner, all without having to invest in expensive hardware or IT staff. As a result, many organizations are choosing to migrate their IT infrastructure to the cloud. However, cloud migration can be a complex and challenging process, requiring careful planning, coordination, and execution. In this article, we will discuss the different cloud migration strategies and the phases that an organization must undergo to achieve a successful migration.

The famous 6 R’s

Organizations use one or a combination of 6 R’s as part of their migration. Each of the 6 R’s has its own Pros and Cons. At a very high level these are as follows:
Re-host: Lift and Shift strategy.
Re-platform: Lift and Modify strategy.
Re-factor/Re-architect: Redesign workloads for cloud infrastructure.
Re-purchase: Abandon existing and purchase a cloud native version of the workload.
Retire: Get rid of workload in the future.
Retain: Keep it as-is.

Cloud Migration Phases

Regardless of the migration strategy, an organization must undergo several phases to achieve a successful migration. These phases are as follows:
We have a 3 phased approach for organizations who wish to move to the cloud. We have defined high-level activities for each phase which can be further granularized, sliced and diced based on an organization needs.

1. End to End Cloud Assessment

High-Level Activities
• Validate Requirements and Identify scope.
• Perform a Holistic Assessment with High-level Target State Design.
• Perform Estimation and Costing analysis.

2. Migration Planning and Roadmap

High-Level Activities
• Create Target State Design and Roadmap.
• Prepare potential Migration Wave Groups.
• Create Migration Plan and Schedule for each Wave.

3. Migration Execution

High-Level Activities
• Implement Target State Design and Architecture.
• Execute Migration Waves.
• Validate Migrations.

Cloud migration is a complex process that requires careful planning, coordination, and execution. By following the above migration strategies and phases, an organization can achieve a successful migration to the cloud, which can lead to improved scalability, reliability, and cost-effectiveness.
