AWS Certified Solutions Architect - Associate (SAA-C03) Exam Guide

Virtual Private Cloud

This chapter delves into the intricacies of AWS Virtual Private Clouds (VPCs), offering you an in-depth understanding of their structure and functionality. You will gain valuable insights into how VPCs provide a dedicated, isolated section within the AWS cloud, empowering you with full control over your network architecture. From setting up IP address ranges and creating subnets to managing intricate network settings, this chapter is designed to equip you with the knowledge and skills needed to efficiently harness the potential of AWS VPCs in your cloud-based projects.

In this chapter, you will cover the following main topics:

  • Introduction to AWS VPCs
  • VPC configuration basics
  • Security in AWS VPCs
  • VPC connectivity

You will start by learning the basics of VPCs and what they are designed to do.

Introduction to AWS VPCs

AWS VPCs represent a foundational infrastructure element, providing you with a dedicated, logically isolated section of the AWS cloud. Within this virtual network, you have full control over the network architecture, enabling you to design, configure, and manage your network resources as per your specific needs.

At its core, an AWS VPC is a virtual network that allows you to define your IP address range, create subnets, and manage network settings. It serves as a private cloud environment where you can launch and operate various AWS resources while maintaining network isolation from other AWS accounts.

An analogy for an AWS VPC is a gated community within a city. In a city, you have various neighborhoods with their own houses and streets, much like the different VPCs within AWS. Each neighborhood (VPC) is self-contained and has its own rules and regulations. The houses (AWS resources) within each neighborhood can communicate with each other freely...

Stateful Versus Stateless

NACLs and security groups control the flow of packets around your VPC using two different methods, stateful and stateless. Stateful means that the security control remembers which packets and interactions were allowed past in one direction and allows them back through the other way. Imagine you are a customer in a restaurant and the receptionist remembers you and lets you leave and come back at will. Stateless means that the security control has no memory of previous events and therefore a packet that has been let past in one direction will not be let back through unless specifically authorized. In the restaurant example, you would need to show some identification or a receipt to the receptionist each time you wanted to leave or re-enter the restaurant. Security groups are stateful, and therefore you only need to create inbound rules to handle these; outbound rules is automatically authorized with the same criteria. NACLs are stateless and therefore both inbound...

VPC Configuration Basics

To effectively use AWS VPCs, you need to understand the available VPC configuration options, which include IP addressing, subnetting, the use of AZs and Regions, and the choice between default and custom VPCs. You will first learn about how IP addresses are assigned and how Classless Inter-Domain Routing (CIDR) notation is used to control the available IPs within subnets.

CIDR Notation

CIDR notation is a compact and efficient way to represent IP address ranges and subnet masks in IPv4 addressing. It is widely used for network design, routing, and specifying IP address allocations. CIDR notation is particularly valuable because it allows for flexibility in dividing and allocating IP addresses without relying on traditional class-based addressing (class A, B, and C networks).

In CIDR notation, an IP address range is represented as follows:

IPAddress/PrefixLength

  • IPAddress: This is the base IP address that represents the network or subnet....

Security in AWS VPCs

Securing your AWS VPC is the most important area of cloud architecture. It is crucial to understand your role within the shared responsibility model, which defines the division of security responsibilities between AWS and customers.

In the realm of AWS VPCs, security is a collaborative effort. AWS shoulders the responsibility for securing the underlying infrastructure, while customers are entrusted with safeguarding their applications and data hosted on AWS resources. This shared responsibility model underscores the need for customers to implement robust security measures to protect their cloud-based assets effectively. In practice, this means that AWS will take responsibility for the security of the cloud, so if someone gained unauthorized access to an AWS-held root or administration account, AWS would be accountable. However, if someone gained unauthorized access to a customer-held root or admin account, the customer would be liable. Figure 2.4 shows the different...

VPC Connectivity

Ensuring effective connectivity within your AWS VPC is a foundational aspect of designing a functional and secure cloud network. To achieve this, you need to configure various essential components and settings that work together seamlessly to enable communication while maintaining security and control. Imagine trying to design the road layout for an entire city to ensure traffic can flow freely, but only certain types of traffic (such as buses or taxis) can use certain roads. AWS provides tools to help users access your services via the internet, as well as allowing operational and development staff backend access to your applications and databases. It also allows you to set up cross-VPC communications using VPC peering. You can now start by looking at how you can enable internet access in your public subnets within your VPC to allow users to connect and to allow your services to communicate with the internet themselves to get updates or to pull in real-time data from...

Hands-on Lab

You are now going to build two VPCs, both with two private and two public subnets, which follow AWS best practices for VPC design. This is a typical VPC architecture where you could create and run an application. Throughout this book, you will add more features to this VPC, including creating servers and simple code to run a small application. Once the VPCs are created, you are going to add internet connectivity to them and then connect the two VPCs together using VPC peering. Make sure you do not end up with overlapping IP ranges.

You have two options to create these VPCs, depending on personal preference. You can use the AWS Management Console, or you can use the AWS Command Line Interface (AWS CLI).

First, we will look at the console steps.

Creating the First VPC

The first step is to create a VPC. Rather than using the default VPC, creating one manually will help you to turn the theory you have learned in this chapter into real-world knowledge:

  1. Log...

Summary

In this chapter, you have explored AWS VPCs from the ground up, covering fundamental concepts, essential components, and crucial security and connectivity features. AWS VPCs serve as the foundation for constructing secure, scalable, and resilient cloud environments, empowering you to design and manage networks tailored to your specific requirements. You have looked into external connectivity, as well as routing between different VPCs. You finished the chapter with a hands-on lab where you built two VPCs, both with private and public subnets, and created a peering connection between them.
