Virtual Private Cloud in AWS

Virtual Private Cloud is one of the most important as well as difficult topic one come across. In this post I’ll make sure to make you understand all the important aspect in a very easy way.

We won’t be deep diving into lot of theory in this vpc amazon tutorial, but will try the practical approach.

So let’s get started,

We will be covering below topics.

1. What is Private Cloud?
2. What is vpc in amazon?
3. VPC Types?
4. Create VPC in Amazon.

What is Private Cloud

When a company set up its own data centre, own servers, storages, network devices to store and process the data either on their personal or private network over the cloud where all authorized users can access it is called Private Cloud.

What is VPC in amazon?

A VPC in amazon is Amazon Virtual Private Cloud (Amazon VPC) enables you to launch AWS resources into a virtual network that you’ve defined. This virtual network closely resembles a traditional network that you’d operate in your own data center, with the benefits of using the scalable infrastructure of AWS.

One network is logically isolated from other virtual network in the AWS cloud, we say logically as nothin is physical in AWS.

VPC Types?

There are two types of VPC.

1. Default VPC: A default VPC is created in each AWS region as soon as an AWS account is created. It has Default, CIDR, Security group, NACL and route table setting. It also has an in Internet Gateway by default.
2. Custom VPC: It’s an VPC on AWS Account, which owner creates. AWS User creating the custom VPC can decide the CIDR. It has default CIDR, security group NACL and route table setting. It does not have an internet gateway.

In the next post we’re going to do the hands on Practical Lab on VPC creation for below scenario.

Important Points:

1. VPC is a Virtual network or Data centre inside AWS for one client.
2. It is logically isolated from other Virtual Network hence Virtual Private cloud.
3. Max 5 VPC can be created in one region and 200 subnets in 1VPC.
4. Once we create VPC DHCP- Dynamic host control Protocol, NACL -Network access control Protocol and security will be created.
