Organizations seeking to move applications into the cloud have five options: rehost on infrastructure as a service (IaaS); refactor for platform as a service (PaaS); revise for IaaS or PaaS; rebuild on PaaS; or replace with software as a service (SaaS).
Organizations seeking to move applications into the cloud have five options: rehost on infrastructure as a service (IaaS); refactor for platform as a service (PaaS); revise for IaaS or PaaS; rebuild on PaaS; or replace with software as a service (SaaS).
"When the CIO issues the simple directive: 'Move some applications to the cloud,' architects face bewildering choices about how to do this, and their decision must consider an organization's requirements, evaluation criteria and architecture principles," said Richard Watson, research director at Gartner, in a statement. "However, no alternative offers a silver bullet. All require architects to understand application migration from multiple perspectives and criteria, such as IT staff skills, the value of existing investments, and application architecture."
The five migration strategies Gartner suggests IT organizations consider are:
Rehost: This involves redeploy applications to a different hardware environment and change the application's infrastructure configuration. Rehosting an application without making changes to its architecture can provide a fast cloud migration solution.
However, the primary advantage of IaaS, that teams can migrate systems quickly without modifying their architecture, can be its primary disadvantage as benefits such as scalability, will be missed.
