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.

The benefit of containers

Customers often ask these questions when it comes to containers:

  • Why do we need containers when we have instances?
  • Don't instances already provide us with a level of isolation from the underlying hardware?

While the preceding questions are valid, several benefits accrue from using a system such as Docker. One of the key benefits of Docker is that it allows you to fully utilize your virtual machine resources by hosting multiple applications (on distinct ports) in the same instance.

Docker uses certain features of the Linux kernel, namely kernel namespaces and groups, to achieve complete isolation between each Docker process, as indicated in the following architecture diagram:

Container layer in application infrastructure

As shown in the preceding diagram, it's possible to run two or more applications that require different versions of the Java runtime on the same machine, as each Docker container has its version of Java and the associated libraries...
