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.

Assessing risk

The first step in managing an organization's risk of adopting cloud computing is an assessment. The assessment should evaluate financial, culture, service integration, regulatory compliance, business continuity, and business or mission system quality.

The impact of financial risk is always critical as it directly drives the return on all investments associated with a cloud computing transition. When using cloud services, costs are directly related to workload and revenue. While this model does reduce some financial risk, it affects other factors differently. The critical assessment factors for cloud ROI risk probability are the following:

  • Utilization
  • Speed
  • Scale
  • Quality

These four factors drive ROI directly because they affect revenue, cost, and the time required to realize any investment return. Differences between actual and projected values indicate a...
