Reliability

How reliable is the system ?

• Notice any points of failure, which on failing can lead to collapse of entire system.

• Any external dependency is prone to failure.

To fix this:

• Have redundancies.
• Have Cloud providers for better reliability like for CDN, for storage etc.
• For external dependencies have backups of using some other external dependencies like multiple payment gateways.
• Have graceful shutdown. Show generic error message.
