Using Event-Driven Architecture With Microservices

The architecture of microservices is on the rise, and is already a major part of many current transformation projects, breaking down traditional, monolithic applications into stand-alone and independently deployed services that are defined using a domain-driven design.

stats from hadith study It was found that more than 60% of the participants used the microservices for a year or more. In particular, finance and banking are leading the way in the use of micro-services, but many other industries are following suit including retail/e-commerce and telecom.

Not only do microservices have the potential to improve scalability, flexibility, and robustness, but the time it takes to deploy and maintain components has also been greatly improved. This is not the case for all microservice architectures. The main obstacles come in the form of ecosystem integration challenges and poor distribution processes.

Breaking the myths of distributed computing

Implementing microservices is more complex than one might initially think, and has been exacerbated by the fact that many DevOps teams fall into the trap of making false assumptions about distributed computing.

List of fallacies of distributed computing It was originally taken up in 1994 by L. Peter Deutsch and others at Sun Microsystems, and still exists today. There are major fallacies that are particularly important for implementing microservices: reliable, homogeneous and secure networks, zero latency and zero transmission cost.

The smaller each microservice, the more your services will have, and the more the fallacies of distributed computing affect user experience stability/system performance. This makes it important to create an architecture and implementation that reduces latency while dealing with the reality of network and service outages.

Detecting the new and updating the old

Microservices require connectivity and data to perform their roles and provide business value, however, data acquisition/connection has been largely neglected and tools severely delayed. We can see this by managing API or gateway products that only support synchronous request/reply exchange patterns. This only exacerbates the challenges of distributed computing – they don’t have the ability to integrate with or get data from legacy systems.

At the same time, event/messaging tools have also been put on hold in the ungainly old world, going against many guidelines for microservices like DevOps and self-service.

Solve the maze of logistic integration

As services become smaller and more unique in purpose, the potential for reuse increases, but this depends on the services’ ability to collaborate. Getting data for green field systems is easy, but microservices always come as a side effect of digital transformation or modernization — or the need to build new capabilities at a faster pace.

break up

Most current systems live on premises, while microservices live in the private and public cloud, so the ability for data to move the unstable and often unpredictable world of WANs is challenging and time-consuming.

There are mismatches everywhere: updates to legacy systems are slow, but microservices should be fast and agile. Legacy systems use legacy communication media, but microservices use open protocols and modern APIs. Legacy systems are almost always on-premise and at best virtualization, but microservices rely on the cloud and IaaS abstraction.

The case becomes clear – organizations need an event-driven architecture to interconnect all these legacy systems against a microservice mismatch.

Create the perfect harmony between microservices

The smaller the service, the less value it provides to the end user – the value comes from the format. Historically, coordination was handled by a central component such as BPEL engines, ESBs, or, these days, API gates.

The description of the orchestra is good – composers create pieces with sheet music that will be played by musicians with different instruments. Each score and its musician is like a mini-serve. In a complex symphony with a hundred musicians playing a wide variety of instruments – like any institution with complex applications – more coordination is required.

Microservices are well practiced

So, one example of a microservice format is when a microservice performs a series of steps within the code. The input or output of the microservice is a domain-significant data event. But the catch is that because the microservice only produces an event, it doesn’t know if or when it will be processed. Other services should register their interest in the event, or group of events, and react accordingly. All this needs to be coordinated microservices.

It’s time to shift the focus

Driven events maximize speed as they free up data from “sleep” to “motion” – consumable in real time. Choosing the right platform for setting up events or messaging is one of the most important steps to realize the massive benefits of microservices.

Microservices by themselves are not enough. Gartner identified this need Since 2018 When she highlighted “events driven” as one of the most important strategic technology trends, citing “digital business is event-driven, so organizations need to invest in event-centric design practices and technologies to exploit digital business moments.”

The full potential of event-driven microservices

Integrating event-driven architecture with microservices can have significant benefits. Developers can build scalable, accessible, robust, and versatile systems that can accommodate and aggregate exceptionally large amounts of real-time events and information.

Not only should modern event platforms be able to deploy to every cloud and platform as a service, but they should also support DevOps automation. In such an ever-changing world, developers need a seamless self-service experience — made possible only through event-driven microservices.
