Engineering Scalable, Elastic, and Cost-Efficient Cloud Computing Applications

Mehr zum Buch

This book offers an overview of the challenges in creating scalable, elastic, and cost-efficient cloud computing services, introducing the CloudScale method, which outlines tools and steps for leveraging these resources. Readers can delve into the scalability problem, identifying anti-patterns and bottlenecks in applications. The method enables software architects to evaluate both existing and planned IT services, addressing critical questions about service quality under varying user loads and ensuring cost-efficiency. Initially, the book emphasizes the significance of scalability, elasticity, and cost-efficiency as essential attributes of modern cloud applications. It provides a concise introduction to CloudScale and details the aspects that should be modeled in cloud applications, utilizing the ScaleDL modeling language. The forward engineering component of CloudScale is discussed for new service development, while reverse and reengineering processes are outlined for modifying existing legacy services. Additionally, the book caters to both business-oriented and technical managers, offering guidance on implementing CloudScale and making informed decisions throughout the process. Demonstrators and reference projects serve as practical examples for learning from experience. This resource is designed for all stakeholders involved in delivering scalable, elastic, and cost-efficient cloud computing applications, including manage
