Understanding the Microservices
Microservices are an approach to modern software applications for boosting the development process. Brands like Netflix, Amazon, Uber, Paypal, and eBay run their products on the microservices approach.
In the monolithic approach, if the functionality of any component breaks down, the entire application used to get shut. Whereas, microservices divide the large software programs into independent and smaller components that reduces the dependency of the functionality on a single component only. Here, developers focus on creating large scale applications as a combination of multiple small services.
What are Microservices?
Microservices are the service-oriented approaches to software development techniques. It creates large, complex applications from multiple small autonomous services. Each service performs a unique functionality, for example, authentication, notification, or payment processing, supporting the UIs, log data creation & management, etc. Each microservice is independent of the codebase, infrastructure, and the database. These services intercommunicate through web APIs and messaging queues. The breakdown of one component doesn't affect the entire function as each of the microservice is a distinct unit within the software development projects.
Why Microservices Architecture came into the picture?
The monolithic architecture had flaws like slow development process, difficulty in code maintenance, unsuitability for complex applications, inflexibility, etc. Microservices based solutions overcame these flaws, it provided solutions like continuous development, scalability, security, easy maintenance, fast adoption process, and an easy deployment process. Microservice architecture improves business performance.
Reasons for upgrading business applications to Microservices Architecture
Microservices architecture is a revolutionary step in software development. Below are the reasons for considering this architecture for developing businesses apps:
- Multiple Component Benefits
The goal behind breaking down the services into microservices is to provide an independency to each component so that it can be deployed, modified and redeployed without making changes to the existing application. This process prevents the entire application from getting redeployed when the necessary changes are meant for only a single service. Developers find it much easier to code and maintain simultaneously.
- Service Monitoring
Since several kinds of services are intercommunicating and internetworking together, therefore the chances of a service failure increases. Keen monitoring of services helps in preventing the risk of failure in the future. It allows the removal of the non-functioning service. Hence, the architecture is failure-proof.
- Improved Productivity and Speed
The complex services are divided into microservices that increase the speed and improves the productivity of the development process. Also, the process of quality testing runs smoothly and quickly, resulting in the effective testing of every individual service.
Future scope of microservices
With the increasing number of microservices in the business, the work of the DevOps team is also increasing. They are now dealing with problems like deployment processes, log management services in a centralized area, keen monitoring of services along with servers, self-management of scripts, etc. The rise in efforts of DevOps could lead microservices in the following directions:
- a). Serverless Architecture:
The future is now, Microservices are executed as functions of service i.e. serverless. Serverless architecture has certain discovery patterns that allow the services to operate as per the demand. It also registers and deregisters itself while performing each command. Better tools for quickly developing and deploying the microservices have reduced the need for a larger investment.
- b). Microservices as PaaS
The advantage of microservices includes the scalability and other benefits offered by the cloud. These services turn a complex issue into an easier task. Microservices provides efficient use of resources in a uniform manner and easier deployment of the scripts. In the upcoming technological trends, microservices will be delivered as Platform as a Service (Paas). Where the microservices will be responsible for transferring the frameworks offering to monitor, register, and log in.
