What are key features of microservices?

The choice highlighting code updates, the use of different stacks for components, and scalability accurately captures the essence of microservices architecture. Microservices are designed to allow developers to build applications as a set of small, independent services that communicate with each other. This modular approach enables teams to update individual services without impacting the entire application, fostering continuous integration and deployment.

Different tech stacks can be employed for each microservice based on the specific requirements or expertise of the development team, enhancing flexibility. Moreover, this architecture promotes scalability, allowing organizations to scale specific components of an application independently, which can be particularly advantageous during peak usage periods.

In contrast, features such as uniform programming languages and single updates imply a monolithic approach, where services are tightly coupled, making independent updates challenging. Additionally, centralized databases and rigid frameworks do not align with the microservices philosophy, which emphasizes decentralized data management and adaptable frameworks to support flexibility and innovation. Similarly, strict dependency management and global deployment do not accurately reflect the independent nature of microservices, as they are designed to minimize dependencies between services, allowing each to evolve separately.
