What are Microservices? The Difference Between Microservice and API
Microservices are currently a hot topic, garnering interest and discussion in the software community and are expected to become the leading trend in architecture design and software development.
Microservices and APIs are two approaches to modular software design. Modular programming aims to design smaller software components that interact with each other to perform complex functions.
Simply put, a microservice is an architectural style that divides the different functions of an application into smaller components called “services.” Each unit is deployed independently and can be scaled, written in different programming languages, and tested separately. This ability allows for quick maintenance and upgrades at a reduced cost without affecting the rest of the application.
While a microservice contains all the code required for a particular application function. An API is a communication mechanism to access that function. Microservices expose functionality via APIs so other microservices can use them when required.
Microservices and API Gateways were created to improve scalability and simplify the maintenance and operation processes of complex systems.
Advantages and Disadvantages of Microservices
Microservices work well with agile development processes and meet the increasing demand for flexible information flow.
Advantages:
- Easy management, upgrading, maintenance, or addition of individual features without affecting the overall project, thanks to the division of services.
- More convenient for functional module testing, as it is now possible to test smaller software blocks.
- Easier deployment, deploying service by service.
- Reduces dependency on a specific technology stack, as all services can be replaced and upgraded over time, as long as they still meet input and output communication requirements.
Disadvantages:
- Developers may find it challenging to maintain distributed systems. Intercommunication between services over the internet is very important.
- Testing interrelated services simultaneously becomes more difficult, as it involves many services over the internet.
- Developing functions involving multiple related services can be challenging as teams must work more closely together to avoid conflicts between services after development.
Common Applications of Microservices
Microservices can operate independently of each other, so programmers tend to apply microservice architecture when developing large, complex systems that require frequent upgrades and maintenance.
- Building Native App applications
- Developers can focus on a few Microservices without worrying too much about other services. This will speed up software development and quickly bring products to market.
- Designing and building Web APIs
- Microservices help improve performance for processing groups rather than a single application. This advantage increases the security level of the overall software.
- Developing expansion and integration with IoT modules
- Microservices allow developers to bridge the gap between languages and technologies. Developers can use multiple programming languages and various technologies in the same product.
