Is Microservices Architecture useful for SaaS product development?

It is a general question for non-techs –what are microservices? Microservices, also known as microservices architecture is an app’s structural approach where independent services are loosely connected and communicate with lightweight protocols.

Due to the smaller and divided codebase, deployment is quicker and more cost-effective. Furthermore, detecting and troubleshooting a mistake is also considerably easier because there is less code to look for. 

Since one service operates independently of the others, it is possible to add new components or improve existing ones without affecting the app as a whole. Different tech stacks can be used for each module, based on what works best for the teams.

Furthermore, the DevOps team can investigate each service independently and build, deploy, and test with agility thanks to the microservices design. When every module is operating well on its own, there is no obstacle, which boosts attention and improves the apps’ total performance.

However, selecting many frameworks might make deployment more difficult. Although API calls are used to manage microservices architecture, building separate scripts for each framework can eventually become uncontrollable and resource-intensive. Thus, select constrained frameworks per your needs.

• Create a separate database: Mostly, many developers use a single database for microservices architecture. Thus, it disregards the use of microservices, and scalability is not found. In solution to this, allow each microservice to access an independent database separated from other services. This also helps in finding errors and not letting other databases get affected by errors in a single service.  
• Regular monitoring: As the number of modules increases, the architecture becomes complex. Thus, developers need to look into the synchronization and seamless functionality of the architecture. Regular checkups and monitoring help in knowing errors on time at any point. You can integrate SDKs or plugins to monitor them accurately.
• Keep microservices smaller: This involves allowing less or limited load on a microservice to function smoothly and less complicated. Furthermore, the smaller the microservice, the easier to manage. Additionally, as mentioned earlier, if a certain service stops working, it won’t affect the app as a whole. Restricted logical functionalities make a program easier to use and less disruptive.
• Ensure security: The complexity and requirement for security grow as the number of microservices rises. Thus, a centralized system is required to prevent attacks, whether they originate from malicious robots or erroneous programming. Installing a system with plugins is necessary to handle security protocols such as authorization and authentication.
• Use Asynchronous Communication: It helps in prioritizing the queues by isolating microservices. Thus, asynchronous communication reduces the load and is more helpful during technical faults.
