## Building & Testing Applications 🛠️

**Develop Locally:**

- [minikube](https://minikube.sigs.k8s.io/docs/start/): Local Kubernetes for easy learning and development.

- [Skaffold](https://skaffold.dev) : Fast, repeatable, simple container & Kubernetes development.

- [Packer](https://www.packer.io/): Automate image builds for efficiency.

- [buildpacks](https://buildpacks.io/) : transform your application source code into images that can run on any cloud 

- [Google code](https://code.google.com/) : use Google code or you can integrate it with ``vs code`` and use it as extention.

-  [Google Emulator](https://cloud.google.com/pubsub/docs/emulator): to emulate GCP Services for local Application development currently you can use it for ``bigtable``, ``datastore``,  ``firestore`` and ``pub/sub``

**Build Your App:**

- ``Artifact``  collection of source code, dependencies, configuration files, binaries, etc, which can be build using different processes.

- ``Google Container Registry``:  Store your container image.

- ``Artifact Registry`` : The next generation of Container Registry. Store, manage, and secure your build artifacts.

- `` Cloud Source Repositories``:  Offers a private git repository 

- `` Cloud build``: where you can build you CI/CD and nicely intgreted with other Google services 

**Testing Tools:**

-  ``Load test`` where you stress your application with a heavy load.
	- Run before putting the application into production
	- Design to simulate the real-world traffic as closely as possible 
	- Test the maximum load you expect to encounter 
	- Test how your Google Cloud costs increase as the number of users increase 
	- Test the application when traffic suddenly increases

-  ``Resilence tests`` where you see what happens when various infrastructure components fails.
	- Test infrastructure failures 
	- App should keep running
	- Example terminate a random instance within an auto scaling group

-  ``Vulnerability tests``  where you see if your application can withstand hacker attacks.  
	- Peer review: Developer check each other's code
	- Integrate static code analysis tools such as ``the vulnerability scanning featur of Google's container analysis service`` into CICD pipeline
	- At least once a year you should run ``penetration tests``

## Deploying Applications 🚀

**Explore:**

- ``GKE (Standard & Autopilot):`` Google Kubernetes Engine for microservices.

-`` Cloud Run:`` Fully managed service for deploying containers.

- ``Pub/Sub:`` Scalable messaging service for decoupled services.

- ``App Engine:`` Build server-side rendered websites.

- ``A/B Testing:`` Test a feature on a small set of users.

- ``Feature Flags:`` Control to toggle features on and off.

- `` Backward Compatibility:`` Ensure app works with older versions.

## Managing Deployed Applications 📊

**Leverage Google Services:**

- ``Cloud Logging:`` Store logs securely at an exabyte scale.

- ``Cloud Monitoring:`` Store application metrics.

- ``SLO/SLI-based Alerting:`` Create SLI-based alerts.

- ``Cloud Profiler:`` Continuous CPU and memory profiling.

- ``Cloud Trace:`` Distributed tracing system for latency data.

- ``Open Telemetry:`` Portable telemetry for effective observability.

- ``Error Reporting:`` Real-time exception monitoring and alerting.

## Designing Cloud-Native Applications 🌐

**Skills to Showcase:**

- ``Deploying Code:`` GKE, Cloud Run, App Engine, Cloud Function, VM.

- ``Caching Solutions:`` Memcache, Redis.

- ``Asynchronous Apps:`` Apache Kafka, Pub/Sub, Eventarc.

- ``Databases:`` Cloud SQL, Cloud Spanner, BigQuery, Firestore, Datastore.
