It is going to be the software-defined, digitization-enabled, cloud-hosted, context-aware, service-oriented, event-driven, and people-centric era. It is a well-known and widely accepted truth that reactive and cognitive software plays a very vital role in shaping up the projected and pronounced era of knowledge-filled and insight-driven services and applications. That is, we need highly responsive, reliable, scalable, adaptive, and secure software suites and libraries to fulfill the identified goals for the forthcoming era of knowledge. There are competent information and communication technologies (ICTs), tools, techniques, and tips emerging and evolving fast to artistically enable the realization of such kinds of advanced and astute software modules.
The quickly-enlarging domain of patterns has been there for several decades. The complexity of software engineering is also increasing in an uninhibited fashion. Software experts, evangelists, and exponents have articulated and accentuated the deft and decisive leverage of software patterns in order to mitigate the rising complexity of software engineering. Therefore, software patterns are widely being recognized as one prime and paramount method for building resilient and versatile software packages and programs. Professionals and professors have been steady in unearthing newer patterns. As a result, a bevy of path-breaking and promising architectural, design, deployment, delivery, and integration patterns are quickly emerging and evolving to speed up and streamline the increasingly complicated processes of designing, developing, debugging, deploying, and delivering robust and rewarding software applications.
This chapter aims to explain the prominent software patterns, particularly the following widely deliberated and detailed architecture patterns:
- Object-oriented architecture (OOA)
- Component-based assembly (CBD) architecture
- Domain-driven design architecture
- Client/server architecture
- Multi-tier distributed computing architecture
- Layered/tiered architecture
- Event-driven architecture (EDA)
- Service-oriented architecture (SOA)
- Microservices architecture (MSA)
- Space-based architecture (SBA)
- Special-purpose architectures
