Cloud migration is the process of moving data, applications or other business elements to a cloud computing environment.

Proficiency

We at Shadow perform various types of cloud migrations .One common model is the transfer of data and applications from a local, on-premises data center to the public cloud. However, a cloud migration could also entail moving data and applications from one cloud platform or provider to another a model known as cloud-to-cloud migration. A third type of migration is to uncloud also known as a reverse cloud migration or declouding where data or applications are moved off of the cloud and back to a local data center.

Cloud Migration Operating Model

Rehosting

Otherwise known as “lift-and-shift.” Depending on the details of the migration, an enterprise may choose to move an application to its new hosting environment without any modification . Most rehosting can be automated with tools (e.g. AWS VM Import/Export, Racemi)

Replatforming

We call this “lift-tinker-and-shift.You may be looking to reduce the amount of time you spend managing database instances by migrating to a database-as-a-service platform like Amazon RDS, or migrating your application to a fully managed platform like Amazon Elastic Beanstalk.

Refactoring / Re-architecting

Re-imagining how the application is architected and developed, typically using cloud-native features.This is typically driven by a strong business need to add features, scale, or performance that would otherwise be difficult to achieve in the application’s existing environment.

Repurchasing

Moving to a different product. I most commonly see repurchasing as a move to a SaaS platform. Moving a CRM to Salesforce.com, an HR system to Workday, a CMS to Drupal, and so on.
