From 0 to working serverless url for a containerized app with google cloud run

235 views

Published on

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.

Presented at Serverless Days Sydney Conference and Serverless July 2019 Meetup.

From 0 to working serverless url for a containerized app with google cloud run

  1. 1. @geshan From 0 to working serverless URL for a containerized app with Google cloud run Geshan Manandhar Senior Software Engineer THE ICONIC
  2. 2. @geshan whoami Geshan Manandhar ● Senior Software Engineer ● Tech solution provider ● Conditional microservices believer 2
  3. 3. I am from Kathmandu, Nepal
  4. 4. I work for THE ICONIC (Tech)
  5. 5. @geshan Agenda ● What is serverless? Why serverless? ● Containers and why use them ● Current serverless FAAS offering ● Cloud Spectrum ● Google cloud run (Serverless + Containers = Bliss) ● Demo ● Performance comparison (Serverless vs FAAS) 5
  6. 6. What is serverless?
  7. 7. @geshan “ 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. 8. @geshan “ 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. 9. Time for Serverless?
  10. 10. PHP community were doing serverless decades ago :)

  13. 13. Why use serverless?
  14. 14. @geshan 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) 14
  15. 15. Focus on your application (code), not the infrastructure
  16. 16. @geshan Serverless (FAAS) Offering (Big 3) 16
  17. 17. Source: https://faasandfurious.com/91There are still servers, you don’t have to manage them.
  18. 18. What are containers?
  19. 19. @geshan “ 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 19
  20. 20. Why use containers?
  21. 21. @geshan Why use Containers/Docker? ● Ship the whole stack with dependencies - reproducibility ● Efficient resource usage - scale horizontally ● Better isolation (cgroups) ● Faster initialization and execution ● Cloud provider agnostic (K8s) ● Dev Side - Quicker onboarding - productive on day 1 21

  25. 25. Serverless and container evolution in the cloud
  26. 26. 26 Control Ease / Abstraction Virtual Machine (VM) Containers PAAS Serverless Cloud Spectrum
  27. 27. 27 Control Ease / Abstraction Virtual Machine (VM) Containers PAAS Serverless Serverless Containers Cloud Spectrum - the sweet spot
  28. 28. @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. 28
  29. 29. @geshan 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 possible) ● The Google Cloud toolset goodness :) ● Getting from 0 to working URL is relatively easy 29
