Microservices Vs Serverless — Which Architecture Should Businesses Choose

Nowadays, Technology to become a primary need in every sector, especially in the Business sector to give tough competition to their competitors. Due to this, it has become imperative for a business to upgrade their businesses according to the upgradation of new technologies. As technologies are rapidly advancing there is a need for applications that can scale easily and are good enough to perform better at a constant speed. Such evolving needs give rise to technologies such as microservices and serverless computing. Like any other technologies, both microservices and serverless are responsive to a particular problem to build an App.

Initially, there were traditional application building done by only one architecture called Monolithic Architecture, but it was very costly and affordable to some businessmen only and became less adaptable and required intensive resources, which gave rise to various other architectures to build an Application such as Microservers and Serverless.

But these two architectures give rise to the question of which gives the best results to choose both technologies to adapt in different ways, have different approaches but give the best result and both have security as their priority to build an App. For a better understanding of the two let’s discuss serverless architecture and microservice architecture.

What is Microservice?

The term Microservices itself refers to an Architectural pattern in which Applications are broken into small services. It is the opposite of Monolithic Architecture where a single entry contains all functions. Microservers have a decentralized architecture pattern in which the application is broken down into a smaller series of independent functions which communicate through Application Programming Interface (APIs). Each Microservices has its libraries, templates, database etc., all of them are tested separately as well.

For better understanding consider examples of food apps which allow us to browse different restaurants, dishes, cuisines etc add them to the cart and then finally complete your order.

There are various ways in which microservices can be executed. For it runs freely, each microservices contains basic elements: its Database, Libraries, Templates etc. All follow the rule of service-oriented Architecture (SOA) where the user gets the freedom of creating his App and running other Applications independently.

DevOps split down all the Application’s functions into smaller applications/ Services that work independently while retaining the main function of the App. These Applications are developed and tested solely before deployment.

This architecture framework is good because if one function of an App gets corrupted and undergoes maintenance it will be easier to fix without affecting another service of a Microservice Application.

Kinds of Microservices

• Stateless Microservice — This kind of microservice does not supply existing data. Every use a new interface is generated and data must be added every time as it can never be preserved.
• Tasteful Microservices — This kind of Microservice always makes a record in the database that makes it easier to code efficiently such data stored externally in a data store like RDBMS, NoSQL databases etc.

Pros of Microservices — Better stability allows easy additions, removal and updation of Individual Microservices.

• Reuses and Adapts different contexts.
• Enhances pliancy to change business logic and use a variety of technologies.
• Removes faults within other services of some Applications.
• Develops, tests and launches service freely without affecting parent Application.

Cons of Microservices — For small businesses who need quick implementation elements too slow and complicated.

• Too complex owing to the components being split.
• Increases overall cost because of Multiple databases and maintenance.
• Expensive as required expertise and computing resources.
