"Microservices" architecture refers to a software design approach where a system is structured as a collection of small, independent services. Each service is designed to perform a specific function and communicates via APIs. This architecture promotes scalability, as different services can be developed and deployed independently, allowing teams to work on various components simultaneously. Additionally, microservices enhance fault isolation; if one service fails, the entire system remains operational. Overall, this approach supports continuous delivery and improves development speed.
