Why software patterns?

There is a bevy of noteworthy transformations happening in the IT space, especially in software engineering. The complexity of recent software solutions is continuously going up due to the continued evolution of the business expectations. With complex software, not only does the software development activity become very difficult, but also the software maintenance and enhancement tasks become tedious and time-consuming. Software patterns come as a soothing factor for software architects, developers, and operators.

Software systems are becoming extremely complicated and sophisticated in order to meet up the newer demands of the business. The field of software architecture helps to smoothen and straighten the path towards producing well-defined and designed software suites. Software architecture is primarily tuned for moderating the rising software complexities and changes. Hence, there are purported efforts to bring forth software architecture patterns to arrive at easy-to-implement and sustainable software architectures. This section begins with some basics about architecture and goes on to elaborate on some of the widely used software architectural patterns.

Architecture is essential for systems that are increasingly becoming complex due to the continuous addition of fresh modules. Architectures generally are decided by three crucial aspects: the participating components, the distinct capabilities of each of those components, and, finally, the connectivity between those components. Establishing software architectures is not an easy job. A variety of factors need to be taken into consideration while deciding the architecture. A number of architectural decisions need to be meticulously considered in order to strengthen the final architecture. Not only functional requirements but also non-functional requirements too need to be inscribed in the architecture. Typically, the architecture pattern is for designing a generic architecture for a system, such as a software solution.
