An application development team has come to you for advice. They are planning to write and deploy an HTTP(S) API using Go 1.12. The API will have a very unpredictable workload and must remain reliable during peaks in traffic. They want to minimize operational overhead for this application. Which approach should you recommend?

App Engine standard environment is ideal for this scenario because it offers fully managed infrastructure, automatically scales to handle unpredictable workloads, and has minimal operational overhead. Its rapid scaling from zero instances and built-in health checks ensure reliability during traffic peaks. While GKE provides container orchestration, it introduces more operational overhead than App Engine standard. Compute Engine with Managed Instance Groups requires more manual configuration for scaling and management. App Engine flexible environment, though managed, uses a custom runtime which can be slower to scale from zero and might incur higher costs than the standard environment for this use case.
