What Is AWS VPC (Virtual Private Cloud) Peering?

Amazon Virtual Private Cloud (VPC) is an private cloud where you can deploy your AWS Virtual machines with controlled access it is completely isolated from the each other the servers which are in the one VPC cannot communicate with the other virtual machines in the another virtual private network.

VPC peering can establish the connection between two Virtual Private Clouds which enables you to route the traffic between two VPCs using the IP address. The virtual servers which are in the same network can communicate with each other with out VPC peering connections but the servers which are in the two different networks can’t communicate with each other with out VPC peering.

Amazon VPC – Introduction to Amazon Virtual Private Cloud

Amazon VPC or Amazon Virtual Private Cloud is a service that allows its users to launch their virtual machines in a protected as well as isolated virtual environment defined by them. You have complete control over your VPC, from creation to customization and even deletion. It’s applicable to organizations where the data is scattered and needs to be managed well. In other words, VPC enables us to select the virtual address of our private cloud and we can also define all the sub-constituents of the VPC like subnet, subnet mask, availability zone, etc on our own. 

  • We can place the necessary resources and manage access to those resources in the VPC, a private area of Amazon that we control.
  • A default “VPC” will be generated when we register an AWS account, allowing us to manage the virtual networking environment, the IP address, the construction of subnets, route tables, and gateways.

What is Amazon VPC(Virtual Private Cloud)?

Amazon VPC can be referred to as the private cloud inside the cloud. It is a logical grouping of servers in a specified network. The servers that you are going to deploy in the Virtual Private Cloud(VPC) will be completely isolated from the other servers that are deployed in the Amazon Web Services. You can have complete control of the IP address to the virtual machines and route tables and gateways to the VPC. With the help of security groups and network access control lists, you can protect your application more....

Amazon VPC (Virtual Private Cloud) Architecture

The basic architecture of a properly functioning VPC consists of many distinct services such as Gateway, Load Balancer, Subnets, etc. Altogether, these resources are clubbed under a VPC to create an isolated virtual environment. Along with these services, there are also security checks on multiple levels....

Amazon VPC (Virtual Private Cloud) Fundamentals

If the subnet has internet access then it is called PublicSubnet. If the subnet doesn’t have internet access then it is called PrivateSubnet. A subnet must reside entirely within one Availability Zone.  An entire subnet must be contained within a single Availability Zone. Access between instances is managed by VPC Security Groups for both inbound and outgoing traffic (EC2 Security Groups can only define inbound rules). We can specify Subnet IP Routing with the aid of the Route Table. If a server/instance which is in a private subnet wants to reach the internet then it must have NAT in a public subnet....

Subnet

A subnet is a smaller portion of the network that typically includes all the machines in a certain area. We can add as many as subnets we need in one availability zone. Each subnet must reside entirely within one availability zone. The public subnets will be attached to Internet Gateway which enables Internet access.  The private subnets will not have internet access. Each and every subnet which is presented in VPC must be associated with the routing table....

Internet Gateway

With the help of IGW (Internet Gateway), the resources present (e.g: EC2) in the VPC will enable to access the Internet. One VPC can’t have more than one IGW  If resources are running in a certain VPC then IGW can not be detached from that particular VPC....

Route Table

Route Table contains a set of rules, called route which helps us to route the network traffic. A single VPC can have as many as route tables it requires. If the dependencies are attached to the route table then they can’t be deleted....

Classless Inter-Domain Routing (CIDR)

A technique for allocating IP addresses and for IP routing is called classless Inter-Domain Routing (CIDR), and its range is 0-32.

Use cases of Amazon VPC

Using VPC, you can host a public-facing website,  a single-tier basic web application, or just a plain old website.
