Mainframe and Cloud-computing are not the same. Here are the differences between these two.
Mainframe
- The controlled environment
- Traditionally requires an administrator to provision computing power for specific tasks
- The mainframe cannot run on X86 architecture
- IBM has been promoting mainframes as cloud platforms
- Mainframe hardware is expensive, licensing and software costs also high
- Porting of applications is laborious
Cloud Computing
- Cloud is that the dynamic provisioning is self-service
- Scale up or down according to user’s demand
- Cloud computing today runs on x86-based distributed architectures
- Cloud is cheaper than mainframe
- Usually, admin not required, but each user can use it in its own way
- Porting of applications from one cloud to another you can do easily
