Microservices refers to an organized and architectural approach to software development where software is made up of small independent services. These services communicate with each other over well-defined APIs.
Getting your microservices architecture right can be quite a challenge. However, these best practices can help you get your microservices right.
One of the major challenges in developing microservices is splitting complex, large applications into smaller, independent modules. It is extremely important to split your microservices the right way. You should create a domain-driven design by consulting with domain experts or the business department.
If the hosting platform has a poor design, you will not get good results from your microservices despite meeting all parameters. You should have a dedicated infrastructure for your microservices, separating them from other components so that you get fault isolation, ultimately giving you better performance.
You must also select the right database for a microservice and get the infrastructure customized for it. Using shared databases for your microservices doesn’t give you the expected outcome.
You should carefully consider how your microservices talk to each other. If there is a single unavailable service, it could potentially create a communication breakdown, causing an entire application to collapse.
Designing an API gateway to handle authentication, responses, and requested is recommended. When you create an updated version, an API gateway will also allow you to redirect traffic to the newer version.
Monolithic architectures are complex and often involve a plethora of tasks, such as deployment, monitoring, repositories, and more. Migrating all of these, especially if you have not handled migrations before, could be immensely challenging. In many cases, it could create a lot of errors and gaps.
To handle this, you could retain your monolithic structure. Other capabilities that you want to introduce could be done as a microservice. When you have enough services in place, you could think of ways of breaking down the old architecture into smaller components and migrating them.
Using the right technology for the right microservice is also extremely important. For instance, you could choose a programming language that you prefer. However, you should ensure that your team is equipped to handle the same. If you choose an architecture that involves a dozen programming languages, you may need to hire more staff to handle it.
For choosing the right technology, you should consider the following aspects:
- Fault tolerance
- Ease of deployment
- Cost of architecture
Microservices can help you manage your applications better, but the transition could be difficult. The above best practices can make things easier for you. For more information on Microservices, please write to firstname.lastname@example.org
