Google Cloud Platform (GCP) is Google’s public cloud offering. Its first product, Google App Engine, was introduced on April 7, 2008, announced at a “Campfire One” event and on the new Google Cloud Platform Blog under the post “Introducing Google App Engine + our new blog.” App Engine let developers run their web applications on Google’s own infrastructure, with the explicit goal of making it easy to start a new web app and then scale it automatically once it reached significant traffic.
App Engine was an early example of platform-as-a-service: developers wrote application code and Google handled the underlying servers, scaling, and operations. The “Google Cloud Platform” brand was adopted later as Google added infrastructure, storage, networking, data, and machine-learning services around that original platform.
Google Cloud is widely associated with technologies that came out of Google’s own engineering practice. Kubernetes, the dominant container orchestration system, originated at Google and is offered as a managed service; BigQuery is its large-scale analytics data warehouse; and its data and AI/ML services build on the same kinds of infrastructure Google uses internally.
GCP is generally counted as the third major hyperscaler, behind Amazon Web Services and Microsoft Azure. Its reputation rests heavily on data analytics, containers, and AI rather than on enterprise software lock-in, reflecting Google’s origins as a web-scale infrastructure company.
