If microservices is considered to transform the way applications and software are developed or designed, Serverless or Functions-as-a-Service ensures the same are run on the cloud in an equally agile and transformative manner. In this situation, once the developed code is pushed to the cloud, the microservice modules or functions are assigned independent servers/fire only when the particular function is called, thereby reducing idle running or overprovisioning. Hence, under this architecture, the enterprise simply needs to push the modules to the cloud environment and the latter takes care of the rest, even to the point of assigning servers to run the same.

Embrace the Functions-as-a-Service approach for the app modernization process including frontend apps, middleware, OS, libraries, frameworks, APIs, virtual machines, and more. Moreover, integrate microservices architecture with containerization to leverage FaaS on GCP to the fullest. With serverless event processing, design and develop the architecture of an event-driven application that ingests data streams, processes the same on the cloud, and synchronizes the results back to back-end databases at zero disruption, null data loss, and ultra-low latency. Leverage GCP native tools to enable serverless operations: Cloud Functions, Cloud Run, etc
