How to fix the error - Status reason CannotStartContainerError: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: \"/bootstrap.sh\": permission denied": unknown?

It occurs when you try to create image from your custom Dockerfile, push it in ECR and try to link that image and create an ECS task and run it. The ECS task would fail to run with this error message.

This can be fixed by providing necessary permission in your Dockerfile as follows:

RUN chmod +x bootstrap.sh # This line should be added
CMD ["/bootstrap.sh"]

Now, build this Dockerfile and push in ECR. The ECS task utilizing this image will be running successfully now.

High availability (Multi-AZ) for Amazon RDS

There is something called failover technology in Amazon. AWS RDS's Multi-AZ deployment uses this technology. If you enable Multi-AZ for an RDS DB, say MySQL DB, RDS automatically creates a standby replica in a different AZ. If the primary DB instance is in AZ-1A, then RDS creates a standby replica in AZ-1B (for example). Suppose I add a new row to a table in the primary DB, then the same row is added, almost in the same time, in the standby replica. This is called as synchronous replication . Thus, standby replicas are useful during DB instance failure/ AZ disruption . How? Because, there is no need to create a backup later because the backup has already been created. This gives high availability during planned system maintenance. Normal backup operation - I/O activities are blocked in the primary database Automated backup operation (standby replica) - I/O activities are not blocked This standby replica is not similar to read replica (which is used for disaster recovery).

Application Load Balancer (ALB)

The ALB spans all subnets in a VPC i.e., it is not inside a subnet but VPC. ALB is bound to Target Groups (TGs). TGs are bound to subnets.
