Microservices Architecture

Operations1/5/2026Advanced Level

Microservices architecture is an approach where applications are built as a collection of small, independent services, each running its own process.

What is Microservices Architecture? (Definition)

A microservices architecture is a method of building software by dividing one large application into many small, independent parts. Each part is a separate service that handles one specific task. For example, an e-commerce site might use one service for product searches and another for processing payments. These services work together by communicating through APIs. This setup differs from older systems where every feature was tied together in one big block. Because each service is separate, developers can update or fix one part without affecting the entire platform. This approach helps businesses stay flexible and prevents the whole system from crashing if one small feature has an error. Modern tools like WISEPIM often connect with these architectures to help product data flow smoothly between different business services.

Why Microservices Architecture is Important for E-commerce

Microservices architecture is a way of building software by breaking a large application into small, independent parts. Each part handles one specific task, such as managing a shopping cart or looking up product data. This structure helps e-commerce sites handle high traffic because you can scale individual pieces without changing the whole system. It also makes it easier to connect different tools like a PIM or ERP. Developers can update or fix one service without the risk of crashing the entire webshop. This flexibility allows businesses to launch new features quickly and adapt to how people shop.

Examples of Microservices Architecture

  • 1An e-commerce site splits login, product lists, and orders into separate, independent programs.
  • 2A PIM system sends product data to webshops and mobile apps as a standalone service.
  • 3A store updates its product suggestion tool without having to restart the whole website.
  • 4A business adds more power to its payment system during big sales without affecting other features.

How WISEPIM Helps

  • Flexible Integration: WISEPIM uses an API-first design, which means it is built to connect with your other business tools. You can add it to your system as a standalone service. It shares data with other software without needing complex custom code.
  • Scalable Product Data: WISEPIM manages product information as a separate service. This allows you to grow your data volume without slowing down other business operations. The system maintains high performance even during busy shopping periods.
  • Agile Development: WISEPIM has a modular structure that helps teams work faster. You can launch new product features or sales channels quickly. These updates happen independently, so they do not disrupt your core business systems.

Common Mistakes with Microservices Architecture

  • Developers often link services too closely by making them share a database or wait for each other to respond. This creates a distributed monolith that is hard to update and prevents services from growing independently.
  • Many teams do not realize how hard it is to manage many small parts at once. It is difficult to track, fix, and update dozens of services while trying to keep all data consistent across the system.
  • Teams often fail to define exactly what each service should do. This leads to services that are either too big or too small. When services do the same job, the system becomes messy and hard to change.
  • It is a mistake to ignore tracking tools like logs and monitors. Without these, you cannot see how data moves between services. This makes it very hard to find bugs or see why the system is slow.
  • Some people use microservices for simple projects that do not need them. This adds too much work and cost for no real benefit. It is better to start simple and only split the system when you truly need to grow.

Tips for Microservices Architecture

  • Give each service one clear job. Make sure every microservice handles a specific business task. This keeps services independent and prevents them from relying too much on each other.
  • Automate your testing and deployment. Use CI/CD pipelines to manage many services at once. This helps you release new features faster and with fewer errors.
  • Set up strong monitoring for all your services. Use tools for logging and tracing to see how data moves. This helps you find and fix problems before they affect users.
  • Plan for things to go wrong. Use tools like circuit breakers to stop one failing service from crashing the whole system. This keeps your platform stable even during errors.
  • Start with a single, simple application first. Break it into smaller microservices only when the project gets too big or needs to scale. This prevents unnecessary work early on.

Trends Surrounding Microservices Architecture

  • AI-driven automation for microservice management: Leveraging AI and machine learning for automated anomaly detection, predictive scaling, self-healing capabilities, and optimized resource allocation within microservice ecosystems.
  • Enhanced observability and distributed tracing: Development of more sophisticated tools and platforms that provide end-to-end visibility into complex microservice interactions, crucial for debugging and performance optimization.
  • Serverless functions (FaaS) as complementary microservices: Increasing adoption of serverless computing to further decompose specific functionalities into smaller, event-driven units that integrate seamlessly with broader microservice architectures.
  • Platform engineering and developer experience: Focus on building internal platforms that abstract away the complexity of microservices, providing developers with self-service tools for deployment, monitoring, and scaling.
  • Sustainability in microservices: Optimizing resource utilization and energy consumption of individual services through efficient code, right-sizing containers, and intelligent scaling to reduce environmental impact.

Tools for Microservices Architecture

  • WISEPIM: A PIM solution designed to integrate seamlessly into modern e-commerce architectures, often leveraging APIs to connect with microservices-based platforms for product data management and syndication.
  • Kubernetes: An open-source container orchestration system for automating deployment, scaling, and management of containerized applications, fundamental for managing microservices at scale.
  • Docker: A platform for developing, shipping, and running applications in containers, providing a standardized way to package microservices with their dependencies.
  • AWS Lambda / Azure Functions / Google Cloud Functions: Serverless computing platforms that allow running code (often specific microservice functions) without provisioning or managing servers, ideal for event-driven microservices.
  • Kong / Apigee: API Gateway solutions that sit in front of microservices, managing traffic, security, authentication, and routing requests to the correct services.
