![]() Drawbacks of MicroservicesĪs with any architectural style, microservices can have a few disadvantages. The scope of SOA is around the standardization of interfaces between applications, while microservices have an application level scope. These interfaces make it easier to use their data and operations in the next generation of applications. SOA works on an interface level, aiming to expose functions as service interfaces. I won’t go too deep on this, but suffice to say that microservices and SOA differ in quite a few areas. The most common form of comparison is between microservices and Service Oriented Architecture (SOA). ![]() Logically separating functional units within an application is not a new concept. All of the above have contributed to the massive adoption of microservice-based architecture, the most prominent example being Netflix. These operations can also be developed in different languages depending on the use case, so a message-board service can be built in Ruby, and the service delivering them to different users can be built on Node. Microservices can be deployed and run in smaller hosts, and don’t have to use the RAM and CPU resources of traditional architecture. Each microservice defines a specific business function, and only defines operations that pertain to this function, making them very lightweight and portable. In order to overcome the growing complexity of managing, updating and deploying applications, particularly on the cloud, the adoption of the microservices architecture took off. Granular scaling of specific functions and modules is also not possible, as teams have to scale an entire application. For example, in a monolithic application, any small modification is tied to an entire change cycle, and these cycles are invariably tied to one another. While there are, and have been thousands of successful monolithic-based applications in the market, development teams are starting to feel the brunt of such large scale deployment operations. All updates to this system will entail deploying a new version of the server side application. In a monolithic application, server side logic is bundled together in the form of a monolith, with all the logic for handling requests running in a single process. A monolithic application is built as one single unit. Any application will consist of a client side interface, a database for storing and handling data, and server side logic. To understand the popularity of microservices, it’s important to understand monolithic applications.

Microservice architecture advocates for developing a single application into a collection of loosely associated services. It also enables an organization to evolve its technology stack, scale and be more resilient with time. The microservice architecture enables the continuous delivery and deployment of large, complex applications. Microservices - also known as the microservice architecture - is an architectural style that structures an application as a collection of loosely coupled services, each of which implement business capabilities. Let’s take a deep dive into understanding more about microservices, how they communicate via APIs, and how tools like Swagger and SwaggerHub can help. In such a crowded street, microservices architecture has picked up a lot of traction and relevance. ![]() As software becomes more and more prevalent and pervasive, different architectural styles are bound to evolve. Software architecture is a high level structure for the development and implementation of software systems. ![]()
