Aws Why Do I Need A Vpc

Instances in either vpc can communicate with each other as if they are within the same network.

Aws why do i need a vpc. Yes in aws you will get one vpc by default. You can also use services such as elastic load balancing amazon rds and amazon emr in your default vpc. But when there is a requirement to create your own network for your own purpose or your company there you need to create vpc.

A vpc peering connection is a networking connection between two vpcs that enables you to route traffic between them privately. Vpc peering comes with the major benefit of improving security by enabling private connectivity between two or more vpc networks isolating traffic from the public internet. You cannot perform edge to edge routing through a vpn connection or an aws direct connect.

One team works in development area and one team works in production area. Designing an aws infrastructure is not so simple as you can imagine. In this case you have a default vpc in each aws region.

You have complete control over your virtual networking environment including selection of your own ip address ranges creation of subnets and configuration of route tables and network gateways. Neither you nor aws will need to plug in a single rj45 jack to configure it. Connecting to corporate networks.

You don t need vpcs to secure lambda unlike ec2 instances which need vpcs to shield them from malicious traffic. Because your traffic never leaves the cloud provider s network you reduce a whole class of risks for your stack. Vpc stands for virtual private cloud which is a very apt name for a service unlike some other aws services i can think of it s virtual because like most user facing things in modern clouds it s powered by software and not copper.

A default vpc is ready for you to use so that you don t have to create and configure your own vpc. Lambda functions are protected by aws identity and access management iam service. Of course you get a nice gui for all the services but the devil is in the details.
