From 0 to working Serverless URL for a Containerized app

Ever wondered if you could run your web application container on a serverless platform? Wait no further with the recent Google cloud run release it is already possible. You can get from 0 to a working serverless URL for a containerized app in no time. Till now there was nothing that married the goodness of serverless with container's ease. Cloud run also makes deploying new versions very easy with its web interface. This talk will be a run-through of deploying and running a simple nodejs app on Google Cloud Run in a matter of minutes.

3. I am from Kathmandu, Nepal
4. I work for SimplyWall.st Make confident investment decisions
5. Geshan.com.np Agenda • What is serverless? Why serverless? • Containers and why use them • Current serverless FAAS offering • Cloud Spectrum • Google Cloud Run (Serverless + Containers = Bliss) • Demo • Projects running on Google Cloud Run 5
6. What is serverless?
7. Geshan.com.np “ Serverless was first used to describe applications that significantly or fully incorporate third-party, cloud-hosted applications and services, to manage server-side logic and state - BAAS. Mike Roberts, Symphonia 7
8. Geshan.com.np “ Serverless can also mean applications where server-side logic is still written by the application developer, but, unlike traditional architectures, it’s run in stateless compute containers that are event-triggered, ephemeral (may only last for one invocation), and fully managed by a third party. - FAAS. Mike Roberts, Symphonia 8
9. Why use serverless?
10. Geshan.com.np Reasons to use Serverless • Server management is not necessary • Cost based on precise usage (by the second) • Inherently scalable (load based autoscaling) • Implicit high availability • Quick deployments and updates (Functions) • Faster to reach a working application (time to market) • More reasons: https:/ /faasandfurious.com/66 10
11. Focus on your application (code), not the infrastructure
12. Geshan.com.np Serverless (FAAS) Offering (Big 3) 12 Compared in this doc
13. Source: https:/ /faasandfurious.com/91 There are still servers, you don’t have to manage them.
14. What are containers?
15. Geshan.com.np “ A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly and reliably from one computing environment to another. - Docker.com 15
16. Why use containers?
17. Geshan.com.np Why use Containers/Docker? • Ship the whole stack with dependencies - reproducibility • Efficient resource usage - scale horizontally • Faster initialization and execution • Cloud provider agnostic (K8s) • Dev Side - Quicker onboarding - productive on day 1 17
18. Decrease the distance between Dev and Ops -- SRE

21. Serverless and container evolution in the cloud
22. 22 Control Ease / Abstraction Virtual Machine (VM) Containers PAAS Cloud Spectrum Serverless Functions (FaaS)
23. 23 Control Ease / Abstraction Virtual Machine (VM) Containers PAAS Serverless Functions (FaaS) Serverless Containers Cloud Spectrum - the sweet spot
24. @geshan Google Cloud Run • Cloud Run is a managed compute platform that automatically scales your stateless containers. • Cloud Run is serverless: it abstracts away all infrastructure management, so you can focus on what matters most — building great applications. 24
25. Geshan.com.np Cloud Run advantages • No need to learn a new paradigm/framework • Run any language/framework/binary -- as it runs containers (not fixed runtimes) • Serverless and fully managed ◦ Cloud Run on GKE can be self managed (Knative) • HTTPs URL out of the box • Custom domains supported • Leverage the Google Cloud toolset 25
26. Geshan.com.np Cloud Run advantages - contd • Manage traffic (% traffic to release) – Gradual roll out • Concurrency - 1 container can handle up to 1000 requests • Unserverless with just one config - min instances • Getting from 0 to working URL is very easy • CI/CD, build packs, startup health check, logs, jobs, monitoring metrics, ◦ For more follow Cloud run release notes 26
27. Serverless + Containers = Bliss :)
