Serverless Architecture
Serverless Architecture is a term that has been getting a lot of attention lately. Naturally, technical leaders are looking to come up to speed on the concept and are evaluating how best to make use of it. The first order…

Designing Resilient Microservices
A Microservices architecture makes it possible to isolate failures through well-defined service boundaries. But like in every distributed system, there is a higher chance for network, hardware or application level issues. As a consequence of service dependencies, any component can be temporarily unavailable for…
Introduction to RabbitMQ & AMQP
In the most recent projects I’ve worked on, the teams I’ve been a part of have decided on the direction of a microservice architecture pattern. The main motivation for this has been to overcome the challenges typically faced in monolith architectures. However, when dealing…
Best Practices for Microservices
Designing Microservice Architecture the right way is quite challenging and difficult. On contrary to Monolith Architecture which gives one solution for all, Microservice Architecture gives a different solution for different problems. If the wrong solution is chosen, then the Microservice…
Design Patterns for Microservice Architecture – Consumer Driven Contract
In Microservice Architecture, there are many Microservices often developed by separate teams. These microservices work together to fulfill a business requirement (e.g., customer request) and communicate with each other Synchronously or Asynchronously. Integration testing of a Consumer Microservice is challenging. Usually, TestDouble is used…
Design Patterns for Microservice Architecture – Externalized Configuration
Every business Application has many configuration parameters for various Infrastructure (e.g., Database, Network, connected Service addresses, credentials, certificate path). Also, in an enterprise environment, the application is usually deployed in various runtimes (Local, Dev, Prod). One way to achieve this is…
Design Patterns for Microservice Architecture – Bulkhead
The Bulkhead pattern is a type of application design that is tolerant of failure. In a bulkhead architecture, elements of an application are isolated into pools so that if one fails, the others will continue to function. It’s named after…
Design Patterns for Microservice Architecture – Circuit Breaker
In Microservice Architecture, where the Microservices communicates Synchronously, a Microservice usually calls other services to fulfill business requirements. Call to another service can fail due to transient faults (slow network connection, timeouts, or temporal unavailability). In such cases, retrying calls…
Design Patterns for Microservice Architecture – Strangler
If we want to use Microservice Architecture in a brownfield project, we need to migrate legacy or existing Monolithic applications to Microservices. Moving an existing, large, in-production Monolithic applications to Microservices is quite challenging as it may disrupt the application’s…
