Question : Can I move my existing DB instances from inside VPC to outside VPC?

4. Yes, Anybody can do that



Correct Answer : Get Lastest Questions and Answer :

Explanation: Currently, direct migration of DB Instances from inside to outside VPC is not supported. For security reasons, a DB Snapshot of a DB Instance inside
VPC cannot be restored to outside VPC. The same is true with Restore to Point in Time functionality. If you need to move your DB Instance from inside to
outside VPC, you will need to export your data from your source DB Instance in your VPC to your target DB Instance deployed outside VPC.

However,You can take a snapshot of your DB Instance outside VPC and restore it to VPC by specifying the DB Subnet Group you want to use. Alternatively, you
can perform a Restore to Point in Time operation as well.

DB Instances deployed within a VPC can be accessed from the Internet or from EC2 Instances outside the VPC via VPN or bastion hosts that you can launch in
your public subnet, or using Amazon RDSs Publicly Accessible option

The basic functionality of Amazon RDS is the same regardless of whether VPC is used. Amazon RDS manages backups, software patching, automatic failure
detection, read replicas and recovery whether your DB Instances are deployed inside or outside a VPC.

Amazon RDS DB Instances deployed outside a VPC are assigned an external IP address (to which the Endpoint/DNS Name resolves) that provides connectivity from
EC2 or the Internet. In Amazon VPC, Amazon RDS DB instances only have a private IP address (within a subnet that you define).

Correct Answer : Get Lastest Questions and Answer :

You are responsible for modifying routing tables and networking ACLs in your VPC to ensure that your DB instance is reachable from your client instances in
the VPC.

For Multi-AZ deployments, after a failover, your client EC2 instance and RDS DB Instance may be in different Availability Zones. You should configure your
networking ACLs to ensure that cross-AZ communication is possible.
