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.

Scalability and elasticity

Scalability has always been a primary factor while designing a solution. If you ask any enterprise about their existing and new solutions, most of the time they like to plan ahead for scalability. Scalability means giving your system the ability to handle growing workloads, and it can apply to multiple layers, such as the application server, web app, and database.

As most applications nowadays are web-based, let's talk about elasticity. This is not only about growing out your system by adding more capabilities but also shrinking it to save cost. Especially with the adoption of the public cloud, it becomes easy to grow and shrink your workload quickly, and elasticity is replacing the term scalability.

Traditionally, there are two modes of scaling:

  • Horizontal scaling: It is becoming increasingly popular as compute commodity has become exponentially cheaper in the last decade. In horizontal scaling, the team adds more instances to handle increasing workloads...
