You may be asked about the AWS VPC peering bandwidth in AWS VPC interview. It’s simply the networking connection between two VPs in the same network. It’s possible to create a VPC peering connection between your own VPs or VPC with another AWS account within the same region. It’s not needed for AWS to break the existing VPC infrastructure to enable VPC peering. There is no need of a special hardware for this purpose. It’s not creating a VPN connection or network gateway within the AWS.

The main intention behind such a connection is to facilitate data transfer across multiple VPNs spanning different AWS accounts. This type of peering is a one-to-one relationship wherein transitive connection is not supported.  And while talking about AWS VPC peering bandwidth, there are no bandwidth limitations for peering connections as well.

This AWS VPC provides the given below features:

IPv4 and IPv6 address book.

Internet connectivity.

Subnet creation.

Route tables.

Elastic IP addresses.

Network/ Subnet security.

Additional networking services.

Yes, VPC works globally. All its components are also working globally. Obviously, they are divided into zone to crate Subnet networks.

We can use the existing VPC infrastructure to create a peering connection. Now, this peering connection doesn’t like any VPN gateway. The most important point is, that it doesn’t rely on any hardware. So there is less chance of communication failure.

I think we can not do this. By default, a peering connection can be done within the same VPC zone.

One data center can connect hardware VPN with AWS VPC. AWS supports internet protocol security VPN connections only. The encrypted data will be transferred. VPN connection helps in data security while transiting. No internet gateway is required to establish a hardware VPN connection with AWS VPC.

Well, VPC is a private network space within the Amazon cloud that enables you to launch AWS resources. It’s the actual networking layer of Amazon EC2, about which we have already discussed. Each private network you create on the cloud will be logically separated from other virtual networks in the cloud.

Although the structure of VPC looks similar to a standard network that you’d operate in a data center, a VPC will have the benefits of the scalable infrastructure of AWS. Another major advantage of VPC is that it is fully customizable. You can create subnets, set up root tables, configure network gateways, setup network access control lists, choose IP address range, and many more in a Virtual Private Cloud.

Beginners who were trying AWS VPC interview questions for the first time used to get confused with this question, since these terms look similar.

Actually, VPS or Virtual Private Server is none other than the host server offered by web hosting companies like BlueHost and GoDaddy (These companies also provide shared hosting services wherein the server is shared by several users). Here, a single host divided to multiple virtual units, each having an independent function. Each of these units is virtual private servers which can work without depending on one another. You’ll get access to the complete physical server including root access.

In the case of VPC, its functions are similar to that of a VPS but its servers don’t have to place in a single location.
