What do you mean by huge data, what's the use case here? the chat history ?


Store it in dynamoDB and build a cache around it ?

Step 1: You need confirm what chat services to support? text, voice, group chatting, saving chat history, etc.
Step 2: Calculate System Design Target. Active users per second?
Step 3: OOD Design. Data Storage and Performance.

Marhaba,

Great piece on Amazon Interview Question for SDE-2s , I’m a fan of the ‘flowery’ style Looking forward to more long form articles ??

I have AWS ec2 six instance for 3 year subscription and type is c4.xlarge for purpose of web-server. due to high usage of RAM/CPU/IO, we wanted extend capacity means resizes resources for existing c4.xlarge to c42xlarge type. may I know the how much extra cost we need to pay for each instance. if we want resize ec2 instances.

Super likes !!! for this amazing post. I thinks everyone should bookmark this.

Thanks and Regards
Radhey
