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.

Return on Investment

Return on Investment (ROI) is the most often used measurement when making project investment decisions. It measures the rate of return versus the cost of the investment. Because ROI is a percentage, it is very easy to make quick comparisons when evaluating multiple options. There are only four ways to either increase revenues or lower costs, improving ROI numbers. The four financial levers are the following:

  • Decrease investment
  • Increase revenue
  • Decrease costs associated with the activity
  • Reduce the time required to attain revenue

Cloud computing can operate any of these levers but the simultaneous achievement of all four is impossible. The relationship between these factors is the most important aspect of cloud ROI, not the absolute values. For example, a project moving to a public cloud may resemble the following: initial investment decreases, operating...
