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).

Rehost

Rehost is fast, predictable, repeatable, and economical, which makes it the most preferred method for migrating to the cloud. Rehost is one of the quickest cloud migration strategies, where the server or application is lifted and shifted from the source on-premises environment to the cloud. Minimal changes may be made to the resources during the migration process.

Customers often use rehost to migrate their applications to the cloud quickly and then focus on optimization when the resources are running in the cloud. This technique allows them to realize the cost benefits of using the cloud.

Customers typically use the rehost technique for the following reasons:

  • The temporary development and testing environment
  • For when servers are running packaged software, such as SAP and Microsoft SharePoint
  • An application doesn't have an active roadmap

While rehost is an application for packaged software and helps us move quickly into the cloud, you may need to upgrade underlying application...
