The world of software development is rapidly evolving, with innovations and approaches being adopted to make the process more efficient.
Microservices architecture is one of these new approaches being integrated with the process of software development and deployment.
What is microservices architecture?
Microservices is a granular architectural pattern that separates portions of an application into a small self-containing services. By definition, microservices are a service-oriented architectural style that focuses on loosely coupled yet independent components of software-related by context.
According to author Chris Richardson,
“Microservices – also known as the microservice architecture – is an architectural style that structures an application as a collection of services that are
- Highly maintainable and testable
- Loosely coupled
- Independently deployable
- Organized around business capabilities
- Owned by a small team”
According to a study by IDC, it is estimated that “90 percent of all new apps will feature a microservices architecture to improve the ability to design, debug, update, and leverage third-party code.”
Considering the benefits of transitioning to a microservices architecture, this is no surprise. Microservices architecture is advantageous in many ways:
- Continuous delivery
- Lower risks
- Increased productivity through automation
These benefits, however, can only be leveraged if the architectural style is adopted properly with the right tools and elements.
There are certain guidelines that firms and developers can follow to make sure that the transition is smooth. Here are a few best practices for microservices architecture that you can follow:
#1 Identify and categorize business capabilities
The best way to plan out the microservices architecture for your product is to first identify your business capabilities and divide your services based on the same. It can be done based on the niche that you wish to build the software in. A Customer Relationship Management software, for example, will have multiple aspects to it including
- Lead capture
- Lead retrieval
- Lead management
Each aspect can be developed separately. You need to identify services that your business provides which are independent of each other yet loosely connected.
The next step then is to plan out a software component for each of these. This will help in providing a direction and a blueprint for your microservices architecture, simplifying the process and avoiding miscommunication.
#2 Automation is your friend
Automation is the key to simplification. Infrastructure automation in case of microservice architecture can help simplify the complexities of development and operations.
Modern cloud infrastructure and AWS systems have paved the way for smarter solutions in a microservices architecture. There are a lot of tools that can automate various aspects of microservices orchestration.
As Eric Knorr, editor-in-chief at IDG enterprises points out, “At hyperscale, large investment made in automation always pays off for both developers and operations.”
#3 Keep a separate data management system for each service
Detailed documentation and logging are necessary to avoid any miscommunication throughout the development process.
A separate database must be kept for each microservice to ensure that any modification within a microservice’s database does not affect other independent microservices. For instance, changes within the database for production should not affect the delivery database.
