What Are Three Major Types of Cloud Migration Strategies?

Working on your cloud migration strategy?
Here are 3 major cloud migration types to consider.

Migrating environments to a cloud-based provider such as Google Cloud is no easy feat, and planning which cloud migration strategy to execute is an absolute must. When planning a migration from an on-premises environment, from a private hosting environment, or from another cloud provider, Pandera can help with our advanced capabilities and cloud migration services

No matter if you’re starting with an on-premise environment with legacy systems and operations, it is important to understand the types of migrations that suit your organization best in order to have the most optimal cloud migration strategy.

The three major types of migrations include: 

  • Lift and shift
  • Improve and move
  • Rip and replace

There are benefits to each type of migration. With strategy and a phased approach, organizations can shift to Google Cloud effectively and efficiently!

Type 1 - Lift and Shift

This type of cloud migration strategy features moving workloads from a source environment to a target environment with minor or no modifications or refactoring. Like the name suggests, this migration is the easiest to perform. Lift and shift migrations allow for teams to continue to use the same set of tools and skills that they were using before. They also support off-the-shelf software!

For example, an organization would utilize a lift and shift migration when a workload can operate as-is in the target environment, or when there is little or no business need for change. 

Even large enterprises, such as one our clients PWC, have successfully executed lift and shift migrations of their various environments. Their journey from AWS to Google Cloud resulted in a flexible on-demand infrastructure with a reduced cost!

Type 2 - Improve and Move

An Improve and Move cloud migration strategy are similar to lift and shift migrations. The biggest difference is that the improve and move migration allows organizations to modify the workloads to take advantage of cloud-native capabilities at the same time the migration is taking place.

For instance, you can improve each workload for performance, features, cost, or user experience. If a  major update to the workload is necessary in addition to the updates needed to migrate, an improve and move approach would be key.

Refactoring may be necessary if the current architecture or infrastructure of an application isn’t supported in the target environment as it is. 

Type 3 - Rip and Replace

Despite the name sounding aggressive, a rip and replace cloud migration strategy is perfect if the current app isn’t meeting an organization’s goals. For example, a company may choose this approach if they don’t want to maintain the app, it’s too costly to migrate using one of the previously mentioned approaches, or it’s not supported on Google Cloud.

Of course, rip and replace migrations do require extra time and effort to successfully implement. Some benefits of this approach include allowing apps to take full advantage of Google Cloud features, such as horizontal scalability, highly managed services, and high availability.

Additionally, the technical debt of the existing legacy version is removed, since the app is rewritten completely from start to finish. 

The path you take for each of your applications will differ depending on your overall cloud migration strategy, as well as the characteristics of the application that you are trying to migrate. You can aim to become cloud-native, or simply lift-and-shift workloads, based on their desired maturity state.
