The service scales with your infrastructure so you can deploy to one Lambda function or thousands of EC2 instances.
      • Minimize Downtime – AWS Code Deploy helps maximize your application availability during the software deployment process. It introduces changes incrementally and tracks application health according to configurable rules. Software deployments can easily be stopped and rolled back if there are errors.
      • Centralized Control – AWS Code Deploy allows you to easily launch and track the status of your application deployments through the AWS Management Console or the AWS CLI. Code Deploy gives you a detailed report allowing you to view when and to where each application revision was deployed.
      • Easy To Adopt – AWS Code Deploy is platform and language agnostic, works with any application, and provides the same experience whether you’re deploying to Amazon EC2 or AWS Lambda. You can easily reuse your existing setup code. Code Deploy can also integrate with your existing software release process or continuous delivery tool chain (e.g., AWS Code Pipeline, GitHub, and Jenkins).

    24. Question 24. What Is Vpc?

      Answer :

      A virtual private cloud (VPC) is a virtual network dedicated to your AWS account. You can configure or create your VPC as per requirement like select region, create subnets (IP- CIDR), configure route tables, security groups, Internet gateway etc to your AWS account By which you can launch your AWS resources, such as Amazon EC2, RDS instances etc, into your VPC.

      So basically you can say that Amazon VPC is the networking layer for AWS Infrastructure.

    25. Question 25. What Is Vpc Peering?

      Answer :

      • A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IP addresses. And instances which are in VPC can communicate with each other as if they are within the same network.
      • You can create a VPC peering connection between your own VPCs, or with a VPC in another AWS account within a single region.
      • If you have more than one AWS account within a same region and wants to share or transfer the data, you can peer the VPCs across those accounts to create a file sharing network. You can also use a VPC peering connection to allow other VPCs to access resources you have in one of your VPCs.
      • A VPC peering connection can help you to facilitate the transfer of data.

    26. Question 26. What Is Vpc Endpoints?

      Answer :

      A VPC endpoint enables you to create a private connection between your VPC with another AWS service without requiring access over the Internet, through a NAT device, a VPN connection, or AWS Direct Connect. They are horizontally scaled, redundant, and highly available VPC components that allow communication between instances in your VPC and AWS services without imposing availability risks or bandwidth constraints on your network traffic.

      An endpoint enables instances in your VPC to use their private IP addresses to communicate with resources in other services. Don’t require public IP addresses to your instances, and you don’t need an Internet gateway, a NAT device, or a virtual private gateway in your VPC.
