Solutions Architect's Handbook

By: Saurabh Shrivastava, Neelanjali Srivastav

Overview of this book

Becoming a solutions architect gives you the flexibility to work with cutting-edge technologies and define product strategies. This handbook takes you through the essential concepts, design principles and patterns, architectural considerations, and all the latest technology that you need to know to become a successful solutions architect. This book starts with a quick introduction to the fundamentals of solution architecture design principles and attributes that will assist you in understanding how solution architecture benefits software projects across enterprises. You'll learn what a cloud migration and application modernization framework looks like, and will use microservices, event-driven, cache-based, and serverless patterns to design robust architectures. You'll then explore the main pillars of architecture design, including performance, scalability, cost optimization, security, operational excellence, and DevOps. Additionally, you'll also learn advanced concepts relating to big data, machine learning, and the Internet of Things (IoT). Finally, you'll get to grips with the documentation of architecture design and the soft skills that are necessary to become a better solutions architect. By the end of this book, you'll have learned techniques to create an efficient architecture design that meets your business requirements.

Scaling your architecture

Let's continue with the e-commerce website example by considering a modern three-tier architecture. Let's see how we can achieve elasticity at a different layer of the application. Here, we are only targeting the elasticity and scalability aspects of architecture design. You will learn more about this in Chapter 6, Solution Architecture Design Patterns.

The following diagram shows a three-tier architecture diagram of the AWS Cloud tech stack:

Scaling three-tier architecture

In the preceding architecture diagram, you can see a lot of components, such as the following:

  • Virtual server (Amazon EC2)
  • Database (Amazon RDS)
  • Load balancer (Amazon Elastic Load Balancer)
  • DNS server (Amazon Route53)
  • CDN service (Amazon CloudFront)
  • Network boundary (VPC) and object store (Amazon S3)

As shown in the preceding diagram, there is a fleet of web servers and application servers behind the load balancer. In this architecture, the user sends an application request to...
