How to Choose the Right Cloud Migration Strategy for a Data Platform

The Lifecycle of a Software Being

The good news is that some data platforms reincarnate in cloud-native applications.

Why Would Your Data Platform Benefit from Cloud Migration

Though migration of a data platform to a cloud offers numerous benefits, do not blindly rest all your hopes on it. No cloud by itself would magically re-architect your workloads or optimize costs. In fact, spending on cloud hosting may exceed the price you are used to paying for on-prem infrastructure. To save yourself from a sticker-shock, choose an optimal approach for migrating a data platform to the cloud.

Pick Your Approach for Cloud Migration

In this post, we focus on 3 out of 6 Rs, six common application migration strategies identified by Gartner and Amazon: rehosting (or lift-and-shift), replatforming, and refactoring (or re-architecting). We’ll help you choose the right migration approach depending on a combination of attributes of your data platform.

Cloud migrations are often complicated by the underlying architecture or restrictive legacy technologies of the data platform, requirements of business users, and peculiarities of tools offered by different cloud providers.

- Rehosting, or Lift-and-Shift Approach to Migration

Which companies is this approach suitable for?

This approach best suits an organization that wants to quickly evacuate a data center, rapidly increase server storing capacity, or quit a license agreement with a hosting provider. For some companies, the cloud serves as a secondary data center. By a lift-and-shift migration, a company can buy some time for planning a pervasive cloud adoption strategy and prepare the ground for transforming the system into cloud-native. The other approaches — replatfroming and rearchitecting — will be easier to accomplish when the platform already resides in a cloud.

The lift-and-shift approach by itself has limited applicability. It is feasible for data platforms driven by certain business requirements, like being cloud-agnostic. Some organizations mentioned earlier, like those in banking, finance, insurance, or healthcare domains, which comply with strict legal regulations for storing sensitive data can lift-and-shift their data platform to store the actual data in a private cloud and be able to quickly transfer it back to on-prem or to a different cloud, if need be.
