If you are dealing with applications or product development, I am sure you would certainly be contemplating on the adoption of Microservices. While Microservices has many benefits, it has a good amount of challenges as well. Hence, you should take an informed and objective decision on whether or not to embrace Microservices. The following questions would help you analyze the key parameters to arrive at a decision.
Stage of your application
Is your application active or in the growth cycle? Do you anticipate several enhancements across your application or is it in a sustenance phase?
Is your application so large that being a Monolith hurts? Measuring the size could be measured by the number of business features or user story points or in KLOC. When the number of business features is > 50 you can tag your application as big enough.
Is your application flaky? Are you scared of making changes to the code without affecting the rest of the application?
Time to release
Do you have to wait for weeks and months to stabilize and release your application to production even for minor enhancements?
Have you encountered many scenarios where fault in some part of the application completely brings down the entire application?
Are you not able to scale your application beyond a point by adding more infrastructure or nodes?
Is your business staggering and losing a lot of ‘business critical’ time due to a lack of knowledge on how to implement them?
If your answer to most of these questions is yes, then your technology is pulling down your business growth and you should definitely look at adopting Microservices. Microservices is the Midas’ Touch of technologies and shall prove to be the differentiator in delivering seamless business processes and agility. Here are a few ways it proves to be a differentiator.
Technical boundaries define the architecture of Monolithic Applications. These applications would ideally have one team working for UI, one for database, one for integration, etc.
Microservices break this and is a paradigm shift from such a model. Here, business functions decide the boundary of Microservices and every individual team owns their own technology stack.
Build Run Repeat
Microservices and DevOps share symbiotic synergies and readily embrace each other. The thought is, the team behind the building service is also the team behind operating and maintaining its code. DevOps makes the code run faster hence bug fixes, new functions and upgrades can be quickly released with better confidence.
Polyglot – Technology Independence
Each Microservice is a world in itself and they communicate with other services through standard channels and don’t rely on technology bindings. This directly provides a positive feed on the ownership and independence of the teams.
The details of code and its complexity are self-contained within the microservices making it a black box for the other components enhancing the logic is not spread across in multiple places. APIs proliferate the dependencies between each Microservice.
Implementing the concept in the proper direction is very key for the success of the process and ensuring the best extract. One best way of adopting such practice is by consuming Microservice accelerators offered by technology implementation partners based on their experience in addressing similar requirements for many customers. Such accelerators offer pre-built functions at right quality and pave way for quicker implementation and reduce the need for Microservice Experts to design things from scratch. Besides, their support also fills the knowledge gap and prevents the troubles faced during its implementation.
Microservices ensures that technology is a part of the solution and not part of the problem. If implemented well, Microservices can lessen complexity at reduced costs. Besides, such individually deployable components make it easy to introduce new features. The best part is, this makes each Microservice component self-sufficient. When nations themselves are moving towards being self-sufficient, software companies becoming self-sufficient is a move in the right direction.
