Architecting Cloud Computing Solutions

By: Kevin L. Jackson, Scott Goessling

Overview of this book

Cloud adoption is a core component of digital transformation. Scaling the IT environment, making it resilient, and reducing costs are what organizations want. Architecting Cloud Computing Solutions presents and explains critical cloud solution design considerations and technology decisions required to be made for deploying the right cloud service and deployment models, based on your business and technology service requirements. This book starts with the fundamentals of cloud computing and its architectural concepts. It then walks you through cloud service models (IaaS, PaaS, and SaaS), deployment models (public, private, community, and hybrid) and implementation options (enterprise, MSP, and CSP) to explain and describe the key considerations and challenges organizations face during cloud migration. Later, this book delves into how to leverage DevOps, Cloud-Native, and serverless architectures in your cloud environment and presents industry best practices for scaling your cloud environment. Finally, this book addresses in depth how to manage essential cloud technology service components, such as data storage, security controls, and disaster recovery. By the end of this book, you will have mastered all the design considerations and operational trades required to adopt cloud services, no matter which cloud service provider you choose.

Business continuity and disaster recovery

A solution is worthless if it cannot deliver service to its intended consumers. This is why business continuity and disaster recovery should always be included when architecting a cloud computing solution. Although the solution architect may exert minimal influence on a solution's operational deployment, the good solution architect considers the following key BCDR questions before presenting a recommended solution:

  • Can the recommended cloud service provider deliver the required service elasticity if BCDR is invoked?
  • Are any other CSPs capable of delivering all the required services under a similar SLA?
  • Does the recommended CSP have available network bandwidth for timely replication of data?
  • Will there be available bandwidth between the impacted user base and the BCDR locations?
  • Are there any legal or licensing constraints that prohibit...
