What is AWS VPC & how beneficial it is for your business?

AWS VPC (Virtual Private Cloud) is one of Amazon Web Services’ most popular and well-known services. This service is primarily concerned with cloud security and access to our data within a third-party data centre.

In both the Compute & Network AWS categories, Amazon Virtual Private Cloud (VPC) is a basic AWS service. Other AWS services, like Elastic Compute Cloud, cannot be used without an underlying VPC network because it is foundational.

What is it used for?
Companies can use AWS VPC to deploy websites and other services in an isolated and secure virtual cloud. It’s a private, provisioned section of Amazon’s virtual cloud with the flexibility and scalability to let a small business establish a new website, or allow a large corporation to roll out a new web application.

AWS VPC is popular for its security, but it also offers the flexibility to create a virtual cloud in the way you want. This can include defining your IP address range, constructing subnets, and configuring gateways and route tables using either IPv4 or IPv6.

How do they function?
Each VPC in the AWS cloud generates a specialized virtual network environment for your AWS account. To provide cloud services, other AWS resources and services run inside VPC networks. Anyone who has managed a physical Data Center will recognize AWS VPC (DC). A VPC functions similarly to a regular TCP/IP network, with the ability to scale up and down as needed. The DC components you’re used to working with—routers, switches, VLANS, and so on—do not exist expressly in a VPC. They’ve been abstracted and re-engineered as cloud applications. VPC allows you to quickly create a virtual network architecture into which AWS instances can be deployed. Each VPC specifies the requirements for your AWS resources, including:

• IP addresses
• Subnets
• Routing
• Security
• Networking functionality

What are the benefits of using AWS VPC?

1. Your data and instances are well-protected with Amazon VPC
Amazon virtual private cloud is a conceptually separated section of Amazon Web Services that allows you to create a virtual network where you can run instances with specific rules and policies to gain internet access. It is similar to having a virtual network within a cloud computing service, with the ability to create a set of rules to get in touch with external resources, whether in another data center or AWS.

To conclude, you may use Amazon VPC to:

• • To deploy your instances, you’ll need an isolated environment within AWS.
  • A virtual network where you can establish your services’ rules and regulations.
  • A fantastic way to create a barrier between your instances and the internet is to expose only a portion of your infrastructure, essentially the only one that needs to communicate with the outside world.
  • The ability to create your IP ranges, subnets, and network settings.

2. Amazon VPC is the most efficient way to link your data centre to your AWS Instances.
Many firms have a private data centre or a group of private dedicated servers worldwide, and they need to share their workload amongst the servers and the public cloud when it comes to public cloud computing. It’s known as a hybrid cloud, and while it’s not the focus of this post, it’s something to be aware of if you’re considering using Amazon VPC.
You don’t need any VPN or external hardware to build up your networks with your own rules in VPC; this is the ideal solution for creating a private channel between your data centre and AWS: pick “VPC with a Private Subnet Only & Hardware VPN Access” from the VPC settings menu. If you’re considering this use, there are a few other things to consider, such as creating a limited group of instances within your VPC that directly backup your own data centre for the most crucial server. This is a clever approach since those instances within AWS are already up and running in the event of a disaster, and you won’t be left waiting for a long time.

3. Not every component of your web application needs to connect to the Internet.
AWS infrastructure design isn’t as straightforward as you might think. Of course, you get a great UI for all the services, one of the reasons you should utilize Amazon VPC to arrange your AWS instances is that not all aspects of your applications need to be visible to the outside world.

In a multi-tier scenario, where a web app uses a database and an application server, AWS VPC allows you to implement the security of your database as well as application server: they will only be accessed by instances functioning as web servers inside your AWS, and not from the internet. This means that you can utilize security groups to set rules and policies that will connect them.

Wrapping up
You can use your private cloud as a disaster recovery site using AWS VPC at a significantly lesser cost than setting up a second data centre on your own. You can rarely decide to start a new website on the spur of the moment. Even a small organization can develop business needs, build features and services, and then run the program on a virtual cloud without first making it secure and trustworthy.
