What are microservices?
If you want to know about Microservices, you are in the right place. Gone are the days of using the traditional monolithic application for software development. Microservices are becoming popular as it solves many IT challenges like scalability, speed and rapid testing processes. Hence from Twitter to Netflix and Amazon to Paypal and many other global giants use Microservices. Check out to know more about what are Microservices, its philosophy, characteristics, pros and cons.
Though the word “micro web services” first coined in 2005 by Dr Peter Rogers, Microservices architecture came to use from 2011. But within less than a decade, it has become the most used by developers worldwide. It is because of its unique philosophy that differs from the traditional monolith application built on the single and autonomous unit. The basis of the Microservice philosophy is that of breaking large software projects into independent, smaller and loosely coupled parts.
What are Microservices?
There is no formal definition or standard model for the term Microservices. It is more of an architectural approach or framework with unique characteristics for developers to build apps as per the growing business requirements. Many consider it a superior SOA or service-oriented architecture, but with methods for arriving at an integrated set of services. It also differs from SOA by focusing on responsive-actor programming style by using fast messaging mechanisms and SQL databases.
The traditional monolithic application now gets replaced by Microservices as enterprises becoming more agile and transforming to DevOps with continuous testing. APIs also help the multiple components of the broken bigger and complex applications into many parts for communicating with each other to execute highly defined and discrete tasks. The many unique characteristics of Microservices that makes it possible to include.
- Breaks down complex software development processes into multiple component services to deploy, redeploy, and tweak independently without compromising the applications’ integrity.
- Have the unique style organized around business capabilities and priorities to make specific products to build businesses.
- Use cross-functional teams to make products based on individual services communicating through message bus to own it for a lifetime.
- Have smart endpoints for processing the info to flow through the dumb pipes for simple routing to generate responses
- Favours decentralized governance and data management to involve various technologies platforms to manage its unique database.
- Has an evolutionary design to cope with failure as the diverse services communicate together to prevent the risk of loss by monitoring it
Pros of Microservices
Microservices with so many excellent characteristics has many pros and cons. The following are its pros to make modular, scalable, adaptable and quickly accessible cloud-based applications.
- Makes it simple for even a small group of developers the freedom to develop and deploy independent multiple components services without affecting each other
- Enables the developers to write code in different languages organized around business capabilities and to use the latest technologies
- Makes it easy for the developers to understand and follow the coding to start the web container quickly and deploy the app fast
- Enable the continuance of work even if one Microservice component or test fails for better fault isolation to change only the application’s specific part without modifying or redeploying the entire application.
- Makes it easy to scale and integrate with third-party services with no long-term commitment to the technology stack and change the fly with no risk.
Cons of Microservices
With many of its unique characteristics and benefits, Microservices also has the following cons:
- Because of the increased complexity by distributing responsibilities with different components, it needs expensive remote calls instead of the in-process calls, coarser-grained remote APIs
- Being a distributed deployment system makes testing tedious, cause information barriers, and duplicated effort.
- Because of its additional complexity, developers have to mitigate fault tolerance, load balancing, network latency and deal with various messages.
The above details about Microservices will surely help you decide if it suits your needs. Get help from professional services to maximize its unique characteristics & benefits and minimize its cons to build your business exponentially.
