Google App Engine provides various developer tools and services to build cloud applications easily. These include Cloud Logging for viewing logs, Cloud Debugging for debugging applications, and Cloud Monitoring for integrating with monitoring systems. It also provides security scanning. Developers can use modules and managed virtual machines on App Engine to build applications. Common runtimes on managed VMs include Node.js, Python, Java, and Go. Local testing and deployment to the cloud is simplified.

- 2. Google App Engine also DevOps enabled - Cloud Logging - Cloud Debug - Cloud Tracing - Security Scan - Push to Deploy
- 4. Cloud Logging Features ● View platform logs ● Export logs to BigQuery, GCS, Pub/Sub ● 3rd party log integrate
- 8. Cloud Debugging ● Push to Deploy ● Runtime tracking and debugging ● Performance tuning
- 10. Cloud Traces
- 13. Security Scan
- 16. Push to Deploy
- 18. Architectures inside GAE Modules & Managed VM
- 19. GAE Modules
- 20. ● Frontend instance (not App Engine Front End) ○ Dynamically created and deleted = low cost ○ Enforce fast response and stateless design ○ Suitable for processing short-lived requests ● Backend instance ○ Statically created and deleted = higher cost ○ No limit for response time, supports stateful design ○ Suitable for batch processing Frontend Instance vs. Backend Instance
- 22. GAE Managed VM
- 23. Choice.. IaaS Raw compute Granular control PaaS Preset run-times Focus is app logic Clusters Data centre as computer Declarative management Managed VMs Beta Bring your own runtime Health-checked VMs Agility NoOps Configurability DevOps Compute Engine App EngineContainer Engine Cloud Endpoints
- 25. Managed VM
- 26. From: https://cloud.google.com/appengine/docs/managed-vms/#standard_runtimes Feature Standard Runtime Custom Runtime Dockerfile Default file supplied automatically by the SDK Hand-written by the developer Dockerfile modifications permitted Yes Yes Languages Python, Java, and Go Any software that can service HTTP requests Configuration file Python and Go modules use app.yaml, Java modules use WAR and appengine-web.xml app.yaml Start/Stop Request Requests are handled automatically by default. You may optionally write your own handlers. Your app will receive these requests but does not need to respond to them. You may optionally write your own handlers. Health Checking Requests are handled automatically by default. You may optionally write your own handlers. You must write your own handlers or disable health checks. App Engine Service APIs Some API support is baked in. Read thePython, Java, or Go page for each runtime. You must use the publicly available REST APIs for cloud services.
