VPCstands for Virtual Private Cloud. Amazon VPC provides a logically isolated area of the
Cloud where users can create AWS resources in a user-defined virtual network. Users
will be having full control over the virtual networking environment, including the
creation of subnets, selection of IP address range and configuration of network gateways
and route tables. Users can customize the network configuration. For example, Users can
create a public-facing subnet for web servers that can access over the internet and can
place a database in the backend to a private-facing Internet.
Components in Amazon VPC
Below are the core components of VPCs. Amazon VPC mainly consists of flowing components:
The subnet is a sub-division of a large network into sub-networks. Because maintaining a
smaller network is easy.
As mentioned earlier, VPC provides full control over the traffic. To accomplish that we
have Route Tables.
A Route Table contains the rules of routing traffic across our network.
Internet gateway is a component that allows our instance in a defined network to connect
to the internet. It allows the user to have a public subnet by providing a route to the
VPC endpoint is used to create a private network between other AWS resources outside our
VPC and VPC without relying on the internet, VPN or NAT devices. Endpoints can be
transferred from one VPC to another one or to any other services.
What can we do with a VPC?
Amazon VPC Types:
There are two types of VPC in AWS
1) Default VPC: which is created by Amazon Web Services
2) Non-default VPC: Created by users to suffice their security requirements
VPC in AWS provides advanced security at the subnet level and also instance level.
With VPC, the user can restrict the users to access the cloud resources.
Easy to set-up and use:
AWS-VPC is easy to setup. Using the command line and AWS Management Console, the user can
easily set up VPC. There will be default VPC in every AWS
account, it’s pre-configured
which lets the user focus on other tasks like building and deploying the application.
Application performance can be affected by the congestion on the internet and slow down
the application or traffic to the application. With Amazon VPC, the probability of
application performance going down decreases.
Many Connectivity options:
Connecting VPC directly to the internet using or via public subnets.
Connect to the internet using private subnets or Network Address Translation (NAT)
