Adoption of Agile methods and approaches in executing transformational initiatives is quite apparent these days. The expectations shift to faster time-to-value has further endorsed the Agile environment that the company must adopt, to deliver business benefits in increments and at a faster rate. The concept of an agile environment is of great value but its realization is hindered by the inherent constraints in practices and procedures that are being followed within an organization. In this article, I will focus on the Enterprise Integration Architecture aspect of the transformation and how Microservices can provide the foundation for speed and resiliency.
Bottlenecks to Agile
A typical organization can relate to the scenario of having a complex environment of applications that are needed to be connected to serve its business operations. A variety of technologies, such as SAP Process Integration and Orchestration (PI/PO), Application Programming Interface(API), and a myriad of middleware connectors are deployed to build point-to-point solutions for information exchange. This integration architecture framework has an inherent constraint of maintaining these integrations that are large, complex, and rigid with agility and are time-consuming in making modifications to adapt to the evolving business needs.
What is Microservices?
Microservices is a service-oriented architecture framework that is flexible, scaleable, and efficient. It is an innovative approach that an organization can move towards to deliver an improved and better user experience. Below is a depiction of a conceptual Microservices architecture framework:
Figure 1 : Conceptual Microservices Framework
Microservices is a collection of services that are small building blocks organized around business capabilities, easily maintainable, independently deployable, and can be implemented using different programming languages, databases, hardware and software environments.
With Microservices based integration pattern, the objective is to develop a catalog of independent deployment units / modules across the enterprise. These modules are self-contained systems and have the characteristics of shorter time- to-market, autonomy, replaceability, and flexibility. A simplistic view of such a pattern is illustrated below:

Microservices architecture framework inherently enables one of the key tenets of DevOps, that is, Continuous Delivery, the ability to promote changes to production or to provision them to the users quickly and with confidence in a sustainable manner.
Opportunity to Transform…
Microservices based architecture framework that is modular, self- contained, and scalable, affords the opportunity to achieve agility that an organization envisions. In your pursuit of providing a seamless user experience, transitioning from a Monolithic architecture to Microservices integration pattern should be an obvious choice.
