Everything Serverless with Google Cloud Run

A lot of developers/engineers fail to understand the platforms that are right for their products or services. Perhaps, engineers feel that Google cloud compute is cool, so it is probably the way they should go or maybe Kubernetes is shiny, they should probably use it but the questions are,
Are you ready to scale?
Do you have intentions to grow fast?
Is this the right approach?
Is it just a portfolio website?

Understanding that we don't need to over-engineer our infrastructure is key. Know what you need and what should be deployed. This talk is trying to buttress a point on how you can get a fully functional app or service using the right infrastructure, get to understand the power of the cloud that hasn't been touched yet and know that it can be better than what we thought.

1. Topic: Everything Serverless with Google Cloud Run @odirionyeo E OBINNA ODIRIONYE | DEVFESTUYO 2019
2. OBINNA ODIRIONYE. Student Partner, Microsoft. Campus Ambassador, Ingressive. DevOps Engineer, Deimos.
4. “Serverless computing is a paradigm shift in application development that enables developers to focus on writing code without worrying about infrastructure.” - Google Cloud What is serverless? “Serverless computing enables developers to build applications faster by eliminating the need for them to manage infrastructure.” - Microsoft Azure
5. “FaaS is a serverless backend service allowing developers to write modular pieces of code on the fly that can be executed in response to certain events” - Cloudflare. Such examples are sending mails, payment processing, uploading file to Google cloud Storage, Posting a tweet and many more. Serverless: FUNCTIONS-AS-A-SERVICE
6. “FaaS is a serverless backend service allowing developers to write modular pieces of code on the fly that can be executed in response to certain events” - Cloudflare. Such examples are sending mails, payment processing, uploading file to Google cloud Storage, Posting a tweet and many more. Serverless: FUNCTIONS-AS-A-SERVICE Serverless/FaaS architecture.
7. Google trends: What does the statistics say over the last five years about serverless?
8. Serverless Cloud Providers(FAAS): 1. Google Cloud 2. Microsoft 3. Amazon Web Services 4. IBM 5. Netlify 6. Zeit 7. Cloudflare 8. Alibaba Cloud 9. Apache and more...
9. Advantages: • No Server Management. • Pay for what you use, reducing cost • Auto scaling. • Fast Deployments and updates. Deeper Dive into Serverless Computing Disadvantages: • Testing and debugging is hard • Performance becomes an issue, Cold boots. • Not built for long processes. • Vendor lock-in a risk. Hint: Use Serverless framework.
10. “Serverless framework is a cross-platform, free and web open-source framework which allows developers to deploy functions to FaaS providers.” What is the Serverless Framework? Supported FaaS Providers(Framework): • AWS Lambda • Microsoft Azure functions • Kubeless • Google Cloud functions • Cloudflare workers • Alibaba Cloud Functions • Apache Openwhisk
11. THE PROBLEMS OF FUNCTIONS: • Unconventional way of writing/deploy apps Microsoft Azure Functions config Netlify functions config
12. Zeit Now config Cloudflare workers Firebase functions config
13. Google Cloud functions: • Node.js 8 -10 • Go 1.11 • Python 3.71 MORE PROBLEMS: Limited Multiple Language Runtimes: Microsoft Azure functions: • Node.js 8 -10 • C# • F# • Bash • PHP(Experimental)
14. KEY QUESTIONS: • What happens to your app when no runtime is available? • What happens when developers want to deploy apps using latest versions of their runtime like Node.js v12 ? • How long do I have wait for my runtime to be released? • Does this mean containers are finally going to die? And more...
15. Developer: Hay God! What sort of compound complex problem is this?
16. Google trends: What does the statistics say over the last five years about serverless and containers?
17. “Serverless has evolved beyond FaaS...” - Kelsey Hightower, Developer Advocate at Google Cloud
18. Serverless + Containers = Google Cloud Run CONTAINERS AS A SERVICE A SOLUTION AT LAST!
19. How containers will be feeling like right now
20. “Containers finally solves the compound complex problems of functions” - Obinna Odirionye.
21. Serverless + Containers(CAAS): • Developers can ship their products and tools with their favorite choice of language(PHP, Kotlin, Java, Ruby, etc) • No more Vendor lock-in problems. • Custom Domain with autoSSL. • Openness to Business Logic. • There’s no need to know Kubernetes.
22. Developers: Obinna, Your talk talk is too much, how do we deploy?
23. Prerequisites: Docker, Basic Knowledge of Containers. Steps: 1. Build your Docker image of your app. [docker build --rm -f "Dockerfile" -t *name of app* /path/to/your/app] 2. Tag your Docker image to the Google Cloud Container Registry [docker tag *name of the built image* us.gcr.io/[PROJECT ID]/*name of the built image*] 3. Push the tagged image to Google Cloud [docker push us.gcr.io/[PROJECT_ID]/*name of the built image*]. 4. Deploy to Cloud Run from your Google Cloud Console. *Here’s a link: Google cloud Run Docs* Packaging and Deployment(CLI)
24. That’s all. Start moving those apps to Serverless.
25. Before using Serverless. After using Serverless.
