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.

CSP performance metrics

In general, performance measures characteristics of the higher service layers depend on those of the underlying technology components. Since consumers typically have no visibility into technology specifics, they can be clueless concerning performance expectations.

The typical user operational metrics used to evaluate cloud service providers are the following:

  • Service response time (delay): The latency time between service request and service completion
  • Service throughput: The number of jobs processed by the service provider within a set time unit
  • Service availability: The probability that the service provider accepts a customer service request at any time
  • System utilization: The percentage of system resources being used for service provisioning
  • System resilience: The stability of system performance over time, especially under bursty loads
  • System scalability...
