Today’s organizations are afraid to become dinosaurs every day. New disrupters gets into your business and upsets everything.
Customers are more demanding than ever and will give up the service too slow to respond. Everything will become necessary yesterday to make your visitors happy.
Now, organizations have almost no time to implement huge applications, which takes months and years.
What they want is more agile, smaller, hyper-focused teams that work together to innovate and bring customer value.
This is where microservices are gaining ground and becoming a quick fix for businesses. They go even further in SOA by dividing each component into truly versatile applications.
Microservices illustrate a technique for breaking down a large, feature-based project into smaller, more manageable pieces. While a monolithic application is a single program with many responsibilities, Microservice-based applications are comprised of several small programs, each with a unique responsibility.
Microservices are small modular services developed and deployable independently. Each component is developed separately and the application form is then simply the quantity of its components. Each service operates as a separate process and communicates with other components with very light methods, such as HTTP / Rest with Jason.
Unlike the old huge enterprise applications that require significant maintenance, microservices are simple to manage.
Here are some features and benefits of Microservices:
Tiny, targeted in scope and functionality
Gives developers the freedom to develop and deploy services independently
Free coupling and can communicate with other services on industry standards such as HTTP and JSON
API-based connectivity
Each service can be coded in many programming languages
Easily deployable and disposable, rejects are possible even several times a day
New digital technology could be easily adopted for a service
Allows to modify the services according to the needs of the company, without enormous cost
Easier tests and versions for individual components
Improved fault tolerance and scalability
The use of Microservices also poses some problems:
Cost of testing at the system integration level
Need to configure monitoring, alerting and similar services for each microservice
Service calls together, so it can be difficult to track and debug
Each service communicates via API / remote calls, which can lead to more overhead.
Netflix has an excellent Microservice architecture that receives more than a billion calls every day, from more than 800 device types, to its video streaming API.
Nike, the apparel and footwear giant, and now the digital brand, uses Microservices in its applications to deliver an extra-ordinary customer experience.
Amazon and eBay are other interesting examples of the Microservices architecture.
GE’s industrial Internet platform, Predix, is based on the Microservices architecture.
So, if your IT organization implements a microservices architecture, here are some examples of an operating system (Linux, Ubuntu, CoreOS), container technology (Docker), planner (Swarm, Kubernetes) and a tracking tool (Prometheus). .
The technical requirements of digital transformation, namely all front / back office systems that seamlessly coordinate the customer experience in an electronic world, are met by Microservices as the preferred architecture.
Microservices help bridge the gap between business and IT. They are a fundamental change in the way IT approaches software development and are needed for digital transformation.
