A Brazilian software agency, Z3 Works, is using a microservices architecture to design and build software projects across various industries, including home-security companies and retailers. For example, their team built an application for a home-security company that collects data from video cameras and doorbells, providing real-time notifications to clients. The microservices approach allows the team to work on small components, update code frequently, and deploy applications effectively without crashing everything else. Redis is used as a caching layer to speed up the application's performance and as a message broker for image requests, ensuring that the system can process large amounts of data in real-time. By using a microservices architecture with Redis, Z3 Works can scale the client's application as needed, making it more effective in the long run, and avoid bottlenecks. The agency is now transitioning another retailer to a similar approach, combining multiple services for improved performance and scalability.
