With approach businesses may not be able to fully leverage the power of the cloud on a long-term basis, however, can benefit from improved performance. The pros and cons of rehosting cloud migration are:

Replatforming

The platforming cloud migration is the next level up from rehosting where you make some minor changes and adjustments to the cloud environment to better improve the performance of the systems and data. However, another you will find is scaling up and down and leveraging other key benefits of the cloud, without fully optimising your system to the cloud. It is cost-effective in its initial phase as it does not require significant time and resources. Some pros and cons of the real platform cloud migration strategy are:

Pros:

  • Quick Migration
  • Only a small level of adjustments required

You may find that some of your systems are redundant or no longer serve a purpose, which makes the case for retiring cloud migration. This is the process of retiring systems that are no longer required so you can remove them from your ecosystem entirely or archive them for a later date. Some pros and cons to consider:

Pros:

  • Optimise storage and memory
  • Simplify your cloud computing

Cons:

  • You may find that you still require those components
