Companies increasingly rely on systems that are secure, flexible and available 24x7. They are often developed in a very short time frame with changing requirements and increasing levels of complexity. Despite this, they must still display acceptable levels of performance, availability, scalability, security and a variety of other non-functional characteristics. These requirements need to be addressed in every part of the system including hardware, software, network topology and system configuration.Architecting Enterprise Solutions is based on real world problems and systems. It takes a practical approach to architectural solutions giving step-by-step advice on how to design high performance, controllable and flexible systems. Design patterns provide a platform-independent way to show tried and tested solutions to common pitfalls and problems encountered when developing high-capability systems. The running case study illustrates the evolution of a system as it grows in functionality and capability, and each chapter closes with a new evolutionary variant of the overall system, illustrating its improved cap abilities.Whether you are looking to gain insight into architectural problems and solutions or in need of practical help in day-to-day system construction, Paul Dyson and Andy Longshaw provide a practical and solution-focused aid to architecting enterprise solutions.
