Even though monolithic software systems still exist, operating on and supporting a lot of our everyday activities, most new systems are designed for—or at least at some point are transitioned to—microservices. Microservices is now probably the most dominant architectural style for modern applications, especially cloud-native applications. In most cases, this approach allows a rapid development cycle for a software product. At the same time, it also provides an opportunity for more cost-effective underlying infrastructure (servers, networking, backups, and so on), especially when relying on cloud providers such as AWS, Google Cloud Platform, or Pivotal Cloud Foundry.
