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…

In Microservice Architecture, the UI usually connects with multiple Microservices. If the Microservices are finely grained (FaaS), the Client may need to connect with lots of Microservices, which becomes chatty and challenging. Also, the services, including their APIs, can evolve.…

If you use Microservice Architecture with Database per Microservice, then managing consistency via distributed transactions is challenging. You cannot use the traditional Two-phase commit protocol as it either does not scale (SQL Databases) or is not supported (many NoSQL Databases). You can use…

If we use Event Sourcing, then reading data from the Event Store becomes challenging. To fetch an entity from the Data store, we need to process all the entity events. Also, sometimes we have different consistency and throughput requirements for…

Once a company replaces the large monolithic system with many smaller microservices, the most important decision it faces is regarding the Database. In a monolithic architecture, a large, central database is used. Many architects favor keeping the database as it…

In a microservices architecture, each microservice exposes a set of (typically) fine-grained endpoints. This fact can impact the client-to-microservice communication. A direct client-to-microservice communication architecture could be good enough for a small microservice-based application, especially if the client app is…

As cloud computing is becoming a more common way of storing and managing data for all small to large-sized enterprises, the importance of understanding data usage patterns and the distance from the requestor entity has become vastly important. Distance is…

The concept of micro frontends, first introduced on the 2016 Thoughtworks Technology Radar, is becoming increasingly popular with engineers and development teams. Since its introduction, more and more teams have utilized this method of architecture to help manage the complexity…

Event-driven Architecture (EDA) is a software architecture paradigm promoting the production and consumption of events. An event represents an action of significant interest. Often, events correspond to a creation or a change of state of some entity. For example, raising an order in…
