Architecting Cloud Computing Solutions

By: Kevin L. Jackson, 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.

Node-based availability

When either an elastic infrastructure or platform is offered by a provider, service availability is defined by the conditions that must be fulfilled by the offering and the time-frame within which service availability is assured. These two factors enable the computation of hosted application availability. With node-based availability, the service provider guarantees the availability of each application component.

Available is generally defined as being reachable and capable of performing its advertised function. This availability time-frame is expressed as a percentage. As an example, an availability of 99.95% means that a component will be available 99.95% of the time. The following figure depicts this example:
