Reading Time: 9 minutes Fintech is no longer just another buzzword; it is an essential part of our everyday life. Even if you don’t trade bitcoins and don’t know how stocks work, there is a chance you still have used one or two fintech apps, e.g. online payments or mobile banking solutions. In fact, the number of fintech startups worldwide has grown from 12,131 in 2018 to 20,925 in Continue Reading
Reading Time: 2 minutes Cross-cutting requirements in Microservices like authentication, authorization, load balancing, rate limiting etc. also required to be implemented. But the question is where it needs to be implemented. Here, no prices for guesses, it should be thorough API Gateway or Edge server only. ‘Spring Cloud Gateway’, a successor of ‘Netflix Zuul’ and pretty good in fulfilling such demands. The first level benefit of Spring Cloud Gateway Continue Reading
Reading Time: 4 minutes Hey guys,Today we’ll find out what circuit breakers are, why you should be using them in any distributed system or microservices architecture along with Istio. Why Circuit Breaker? We’ve got a series of microservices here that don’t have to be microservices ( in Kubernetes these will be pods, services, etc ). They’re going to be connected together in some way, a cascading failure is where Continue Reading
Reading Time: 4 minutes Introduction In this Digital-first era, technologies are evolving faster. It helps technologists to develop and deploy faster, more performance-oriented, efficient, and lower memory consumption applications.Quarkus is one such initiative from RedHat. It is designed and developed by RedHat, keeping cloud-native, serverless, and containerized applications future in mind. As per RedHat definition: “Quarkus is a full-stack, Kubernetes-native Java framework made for Java virtual machines (JVMs) and Continue Reading
Reading Time: 4 minutes Resilience4j at a Glance Scope of this article is applications based on microservice architecture. Let me begin with a question, what is most important non-functional requirement from any application? Undoubtedly the answer of this question will be ‘Robustness’. This means applications must behave reasonable with respect to adverse scenarios. Against all adverse scenarios application needs to take either corrective action or redirect to reasonable action Continue Reading
Reading Time: 3 minutes What is Domain? To define domain-driven-design we should first establish what we mean by domain. The common dictionary definition of the domain is a sphere of knowledge, influence, or activity. In the context of software engineering, it refers to the subject area on which the application is intended to apply. For example, if you are building an E-commerce software, in this case, sales will be Continue Reading

Reading Time: 3 minutes In this blog, we will be talking about the Micronaut framework, how its better than other frameworks in the same trail. What makes it different from other frameworks so let’s get started.
Reading Time: 2 minutes Serverless Computing, I hope you have heard or read this term in many tech talks and articles. And that’s because it is trending these days. But what is it? That is the first question that pops up in our mind as soon as we hear or read the term Serverless Computing. In this blog post, we will not only learn about serverless computing, but also Continue Reading
Reading Time: 4 minutes What Happens When Reactive Meets Microservices? It would be beneficial if you understand the concepts of Reactive Architecture before diving into Reactive Microservices. You can read about Reactive Architecture here: Leaning Towards Reactive Architecture In this article we will cover transition from Monoliths to Service Oriented Architecture to Reactive Microservices by applying isolation techniques to the application. What are Monoliths? To start explaining the microservices Continue Reading
Reading Time: 5 minutes Hi all. I hope that you all must have heard of Serverless architecture. It’s quite popular and gaining a lot of attraction. In this blog, I’ll drive your attention towards Serverless architecture, and, then to Stateful Serverless architecture. We will see the pros and cons of such an architecture, followed by the concept of stateful serverless. Thus the title is, From Serverless to Stateful Serverless. Continue Reading
