Introduction
In this lesson, we will deep dive into the security of AWS VPC. VPC is the most important component of networking services in AWS. Networking services are one of the foundation services on the AWS cloud. A secure network is imperative to ensure security in AWS for your resources.
We will look at components that make up VPC, such as subnets, security groups, various gateways, and so on. We will take a deep dive into the AWS VPC features and benefits such as simplicity, security, multiple connectivity options, and so on.
We will look at the following most popular use cases of VPC that use various security and connectivity features of VPC:
Hosting a public-facing website
Hosting multi-tier web applications
Creating branch office and business unit networks
Hosting web applications in AWS cloud that are connected with your data center
Extending corporate network on the cloud
Disaster recovery
AWS provides multiple measures to secure resources in VPC and monitor activities in VPC, such as security groups, network access control list (ACL), and VPC flow logs. We will dive deep into each of these measures.
Next, we'll walk through the process of creating a VPC. You can either choose to create a VPC through the wizard, through the console, or through the CLI.
Furthermore, we'll go through the following VPC connectivity options along with VPC limits in detail:
Network to AWS VPC
AWS VPC to AWS VPC
Internal user to AWS VPC
We'll wrap up this lesson with VPC best practices.
Throughout this lesson, we'll take a look at AWS architecture diagrams for various use cases, connectivity options, and features. The objective of this lesson is to familiarize you with AWS VPC and let you know about ways to secure your VPC.
