A company runs its critical portal on its On-prem datacenter on docker containers with a PostgreSQL database of size 40 TB. They are looking to migrate their existing portal to AWS to enhance user`s experience with less burden on Infrastructure management. Which of the following methods should they use? (Select TWO).

Answer options:

A.They should choose EC2 to deploy the containers on ECS and move the 40TB data using snowball on AWS.
B.They should choose Fargate to deploy the containers on ECS and move the 40TB data using snowball on AWS.
C.They should choose EC2 to deploy the containers on ECS and move the 40 TB data using 1Gbps Direct Connection Connection.
D.They should use the RDS Aurora PostgreSQL Database in AWS.
E.They should run the PostgreSQL on top of EC2 Nitro Based system for better Database Performance.

Answer: B and D are correct.
Option A is Incorrect because deploying container on ECS using EC2 will require management task.
Option B is Correct because Fargate removes the management task of container on ECS. Also, moving 40TB of data one-time using snowball will be the right strategy here as this is the one-time movement of large data.
Option C is Incorrect because deploying a container on EC2 will require lots of management task and also moving 40TB using 1GBPS will not right strategy here as this is a one-time data movement.
Option D is Correct because RDS Aurora PostgreSQL provides better performance.
Option E is Incorrect because running PostgreSQL in EC2 will require lots of management task like installation, Patching etc
