What is serverless? 

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 

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 

Why use serverless? 

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 

Focus on your application (code), not the infrastructure 

Geshan.com.np Serverless (FAAS) Offering (Big 3) 12 Compared in this doc 

Source: https:/ /faasandfurious.com/91 There are still servers, you don’t have to manage them. 

What are containers? 

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 

Why use containers? 

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

@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 

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 

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 

Serverless + Containers = Bliss :)
