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.

Immutable deployment

An immutable or disposable upgrade is an easier option if your application has unknown dependencies. An older application infrastructure that has been patched and re-patched over time becomes more and more difficult to upgrade. This type of upgrade technique is more common in an immutable infrastructure.

During the new release, a new set of server instances are rolled out by terminating older instances. For disposable upgrades, you can set up a cloned environment with deployment services such as Chef, Puppet, Ansible, and Terraform, or use them in combination with an auto scaling configuration to manage the updates.

In addition to downtime, you need to consider the cost while designing your deployment strategy. Consider the number of instances you need to replace and your deployment frequency to determine the cost. Use the approach that best fits, taking your budget and downtime into consideration.
