What are Microservices? Explained.

Mohammed NaserMohammed Naser

Microservices greatly benefit most agile and DevOps teams. Many tech giants have transitioned from monolithic architectures to microservice architectures. Unlike monoliths, a microservice application isn't built as single, autonomous units. Thus, changes to the application don't affect the entire system and are much faster. For the uninitiated, here is a glance at the technology and its various attributes.

What are Microservices?

Microservices is an application development approach in which the larger application is crafted from modular services and components, with each module supporting specific tasks. Microservices use a simple, well-defined interface, such as APIs, to facilitate communication with other sets of services.

In such an architecture, applications are categorized into services, and each service manages its own databases and runs unique processes. Furthermore, they can also execute tasks such as providing authentication, generating alerts, logging data, etc. For development teams, microservices bring a more decentralized approach to building software, providing independence in isolating, rebuilding, redeploying, and managing each service.

Characteristics of Such an Architecture

Microservices have a lot of discrete components and services. The typical characteristics of microservices include:

  • Unique design and deploy services to accomplish tasks
  • Decentralized structure with almost zero dependencies
  • Resilient architecture with maximum fault tolerance.
  • Using APIs to communicate
  • Data separation capabilities

Benefits and Challenges of Microservices

Microservices architecture deployments have grown over the years. Here are some of the benefits they bring in:

  • Development and deployment using different tools and languages
  • Reduces development period
  • Easy scalability
  • Adaptiveness to other projects and containers
  • Provides better fault isolation
  • Less resource-intensive and faster load balancing and deployment
  • Small teams work well on them

However, there are also some challenges here, such as:

  • Granularity issues
  • Designing communication takes effort
  • Complex testing
  • Complex management and control
  • Latency issues
  • Security needs

Deploying Applications with Microservices

There are three factors that make microservices viable as a software architecture solution. They are;

  • Containers
  • Orchestration tools,
  • Service mesh

Advancements in these factors and other related tech have reduced the complexities in microservices, and have led to increased adoptions.
