Microservice architecture: Everything you need to Know.

 “The microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API.”-Martin Fowler

 

Microservice Architecture commonly referred as Microservices are small autonomous services that work together, modelled around a business domain. It is a modern architectural pattern for building an application. As compared to traditional or monolithic architecture, microservices are implemented as REST API and use a delivery pipeline for deployment. Typically, each microservice run in the container that provide a lightweight runtime environment. Some of the most innovative and profitable microservices example of the companies who over the time dismantle their monolithic applications and successfully adopted the microservices are- Amazon, Netflix, Uber and Etsy. In a recent survey of IBM of 1,200 developers and IT executives, 87% of microservices users agreed that microservices adoption is worth the expense and effort. This survey clearly states its popularity amongst the developers. In 2005 Peter Rodgers, first coined the term “Micro-Web-Services” and two years later software architect Juval Lowy expanded on the idea of granular use of services and inspires several promising outcomes.

They are enabled by:

• Containerization (Docker)
• Container Orchestration tools (Kubernetes)
• Cloud Computing
• API Gateways

Difference between Monolithic and Microservices:

Monolithic consists of one system where codebase, business logic and other part are interconnected and dependent on one another whereas microservices involves infrastructure with individual services that work independently. Monolith use a single process and scale by replicating on multiple servers. Microservices use separate services and then scale by distributing them across servers and replicating only some time.

How does Microsoft Architecture Services work?

When we use microservices, we isolate software functionality into multiple independent modules which communicate with each other through universally accessible application programming Interface (API).

 

Advantage of Microservices:

• Each microservice can be deployed independently and allow for more team autonomy
• Easier to scale faster and cost-efficiently using Microservices.
• Microservices prevents cascading failures and reduces downtime through fault isolation.
• Smaller codebases make easier maintenance and deployment.
• Each microservices can use different technology based on the business needs.

Conclusion:

Microservices is more suitable and beneficial for complex and evolving applications. It is ideal when it comes to the platform consisting of many users journey and workflow.
