Microservices architecture for E-commerce

Microservices architecture for E-commerce

The client is a large online store, with about 25000 unique visitors per day and more visitors on promotional days. For the efficient customer service, it was necessary to have a live chat for the website: the company tried various popular online consultants, but all of them could not keep up with the high load. Softvoya team suggested the client to use a ready-made chat module based on Upservice platform, which works perfectly with high traffic and has a great performance due to the microservice architecture on which it is designed.

Duration: 1 month


The client (a large online store from a retail chain) needed a convenient chat for communicating with site visitors.

  • The chat should cope with high load (25000+ users per day), work quickly and without interruptions. 
  • The design of the chat should match the company’s corporate style.



Our team streamlined the development process by selecting the most relevant technologies and choosing the best development practices: 

  • Widget is developed on microservice architecture: monolithic architecture does not allow scaling parts of the system, so Softvoya team decided to break monolith (application built as a whole) into microservices (small components).
  • Development on microservices architecture allowed a separate module of the complex system (chat) to scale and thus to cope with large loads – to better support a large number of sites with high user traffic daily.
  • The design of the chat is fully consistent with the corporate identity of the company.

How it works

The customer was already a user of the Upservice platform, so our team suggested to take advantage of using the Upservice widget and installing it on their website to communicate with users:

  • Customer creates a channel in Upservice 
  • Specifies the site where he wants to attach the widget
  • Selects the widget interface and adjusts it to the design of the website
  • Installs the script through the admin panel 
  • Widget appears on the site
  • Site users can write in a chat: ask questions, send comments and suggestions

Channel operators work in the Upservice system and receive messages online (and reply in the Upservice interface), while users receive a reply in the chat on the website. 

Widget installation and configuration takes a few minutes, while the chat works quickly and without interruptions, coping with high loads.
