Microservices architectures are becoming increasingly popular among fast-growing and highly competitive companies due to their flexibility, scalability, and ability to support rapid changes in the marketplace. In contrast, monolithic architectures package a series of business capabilities into one, with tightly coupled codebases that can make it difficult to manage and scale individual components. Microservices offer a modular approach, allowing teams to mix and match tools and services as needed, while also providing language- and framework-agnostic independence. This leads to increased agility, faster deployment cycles, and the ability to add new business capabilities and features more easily. However, microservices can be more complex to manage, and their individual components may require more resources to maintain. Monolithic architectures, on the other hand, are often more rigid, with a single codebase that must be managed as a whole, which can make scaling and deployment more complex and time-consuming.
