When to Use Cloud Resources


  • You are using on-premises virtual servers and storage for your services.
  • You wonder whether you should move your services to public cloud, such as AWS or Azure or Google Cloud, in order to reduce hardware and maintenance cost.


  1. It is common that cloud resources for system running 24/7 are much more expensive than private resources.

  2. Cloud resources are suitable forĀ 
    • a very big system that needs to be run only once within limited time, or
    • startup with many consolidated services on single small virtual server, or
    • testing purpose, or
    • a very big company with big budget who want reliable and elastic resources.
