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).

In-place deployment

In-place deployment is a method of rolling out a new application version on an existing fleet of servers. The update is done in one deployment action, thereby requiring some degree of downtime. On the other side, there are hardly any infrastructure changes needed for this update. There is also no need to update existing Domain Name System (DNS) records. The deployment process itself is relatively quick. If the deployment fails, redeployment is the only option for restoration. As a simple explanation, you are replacing the existing application version (v1) on the application infrastructure with the new version (v2). In-place updates are low-cost and fast to deploy.
