What is a microservice framework?

A microservice framework is used to build a microservice architecture . The framework itself reduces the amount of code you have to write, for example, while creating a web application exclusively in JavaScript code.

Microservice architecture implies that individual apps comprising an eCommerce tech stack are separately developed, deployed, and managed. A specific microservice is created to play a particular role, like, for example, delivering product search reviews, checkout, wish lists, etc. 

A decentralized development process allows you to experiment with different solutions and implement new functionalities for customers before your competitors do.

How microservices can help the eCommerce businesses

Online shopping continues to evolve, and the future is expected to bring the adoption of tech shifts that accelerate tech deployments, online marketing activities, and scaling. With the burdens monolith eCommerce applications cause, microservices open up an easy way towards the digital transformation.

Benefits of microservices for IT teams in eCommerce

Microservices provide many benefits to the tech infrastructure, which boosts overall organizational efficiency.

Microservices:

• can be developed and deployed using different languages and tools

• require less development time and a more nimble approach

• scale fast

• are reusable - can be reproduced in different projects

• incorporate better failure isolation

• are speedier and significantly less resource-consuming when it comes to deployment and load balancing

• require less time spent on implementation

Benefits of microservices for Business teams in eCommerce

Although the benefits of microservices are primarily addressed to IT teams, the business side of eCommerce also gets a solid operational boost.

• Changes to the frontend can be introduced quickly and without developer help. Once the development is freed from a rigid technology stack of a monolith and its dependencies, marketing teams can iterate at scale. Each business function of a monolith can be replaced with a dedicated microservice. By providing a custom pattern once, marketing teams gain a higher level of independence in activities oriented towards customer experience.
• Easy scaling. Microservices architecture enables easy and fast scaling. Each service has its own life cycle – it’s created, modified, tested independently and can be removed if needed without disrupting the whole system. With that flexibility, growth-oriented eCommerce can plan investments gradually.
• Daily operations that are more resilient. Malfunctions in a single microservice don’t affect the entire system and can be handled by a dedicated team, which is non-dependent on dev teams working on other parts of the eCommerce stack. 
• Cost optimization. The entire infrastructure can be highly optimized for costs as microservices are cloud-native. Thus each one can be hosted on a different cloud instance based on its bandwidth requirements.

Why do microservices matter in eCommerce?

The architecture of microservices secures eCommerce so it can respond quickly to market trends and customer expectations. Decoupled, the microservices-oriented architecture enables:

• Fast implementation of various new touchpoints to the frontend

• Implementation of headless systems that provide multiple frontends to work on one backend system

• Separation of the frontend from the backend; therefore, the frontend traffic does not affect the backend

• An open path to compose eCommerce software with 3rd party applications

• Rapid performance

• The best technology stack implementation, which gives merchants the freedom to pick the functionalities and features essential for business

  

Microservices with their architecture enable eCommerce to scale fast and compose their tech stack with modern solutions.

Loosely coupled architecture reduces the dependency of marketing and IT teams. Daily operations, thanks to well-tailored dedicated services, happen faster. Any changes or extensions don't take months. At the same time, the eCommerce team doesn't risk putting the entire system down with a minor update.
