“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 

“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 

“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. 

Google trends: What does the statistics say over the last five years about serverless? 

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... 

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. 

“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 

THE PROBLEMS OF FUNCTIONS: ● Unconventional way of writing/deploy apps Microsoft Azure Functions config Netlify functions config 

Zeit Now config Cloudflare workers Firebase functions config 

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) 

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... 

Developer: Hay God! What sort of compound complex problem is this? 

Google trends: What does the statistics say over the last five years about serverless and containers? 

“Serverless has evolved beyond FaaS...” - Kelsey Hightower, Developer Advocate at Google Cloud 

Serverless + Containers = Google Cloud Run CONTAINERS AS A SERVICE A SOLUTION AT LAST! 

How containers will be feeling like right now 

“Containers finally solves the compound complex problems of functions” - Obinna Odirionye. 

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. 

Developers: Obinna, Your talk talk is too much, how do we deploy? 

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) 

That’s all. Start moving those apps to Serverless.
