Google App Engine 

Google App Engine is a Platform-as-a-Service (PaaS) offering from Google Cloud, tailored for hosting monolithic applications. It supports multiple programming languages, such as Python, Java, Go, and Node.js, and abstracts infrastructure management to allow developers to focus solely on code. App Engine automatically scales applications based on demand and provides integrated support for versioning, traffic splitting, and monitoring, making it a suitable option for rapid application deployment.
