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

Diving Into Reactive Microservices

Reading Time: 4 minutes 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 it’s useful to compare it to Continue Reading

Serverless to Stateful serverless

From Serverless to Stateful Serverless

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

Authorization using Bundle-API in OPA

Reading Time: 3 minutes In the previous blogs (Policy Enforcement using OPA and Go Through with Rego components), we have understood that what is OPA, how it works and the different components of rego so In this blog, we are going to understand what is bundle-API, how we can integrate with OPA and how to inject OPA policy and data at a dynamic time on the cluster with bundle-API.

Understanding data persistence in Lagom

Reading Time: 4 minutes When we create any microservice, or in general any service, one of the biggest task is to manage data persistence. Lagom supports various databases for doing this task. By default, Lagom uses Cassandra to persist data.

Authentication and Authorization in Microservices

Reading Time: 3 minutes Microservices Architecture has been gaining a lot of ground as the preferred architecture for implementing solutions as it provides benefits like scalability, logical and physical separation, small teams managing a part of the functionality, flexibility in technology etc. But these benefits come at a cost of simplicity since microservices are distributed the complexity of managing them increases. One of the key challenges is how to Continue Reading

Microservices and the Saga Pattern

Reading Time: 10 minutes Microservices have become a crucial part of any enterprise these days, no matter if it is a big or a small enterprise. When something this big is present in the market why not see some fundamentals of the same? So here we’ll go through the concepts like what is a microservice and Saga Patterns that an ideal microservice should have.

Custom ErrorHandlers and Lagom

Reading Time: 3 minutes Hello everyone, it’s been quite a while now since I started working on Lagom(java) and it was only recently when I came across a scenario wherein I was required to override the ErrorHandler provided by Play in my Lagom microservice. As you all already know that Lagom is built on top of Play and Akka, so there will be times when we’ll be required to Continue Reading
