3. What is serverless?
4. No Server? 🤔
5. Ibadan Building applications without worrying about servers.
6. Serverless is a cloud computing model that enables developers build and run applications without managing the underlying infrastructure. OpenAI. (2024). ChatGPT [Large language model]. https://chatgpt.com
7. Build and scale to millions on battle tested infrastructure Mostly cheaper if used correctly Faster software delivery cycle Why Serverless? Would you rather not worry about servers 😄
8. Google Cloud Functions Now Google Cloud Run functions
9. Cloud Run functions => Run functions in the cloud
10. Package application components into functions Visualizing Serverless Flow on Cloud Run Cloud Run Global Audience 󰞐
11. Cloud Run functions is a simple and intuitive serverless compute offering from Google Cloud Platform. Just write your code and let Google Cloud handle the operational infrastructure.
12. Why functions? 🤨
13. Why functions? Something to invoke! You’re free to use any other construct of your programming language.
14. Native support a lot of programming languages Support for other languages via containerization Pay as you go! Integration with Google Cloud ecosystem Google Cloud Run functions highlights 1. Go 2. NodeJS 3. Python 4. Java 5. .NET Core 6. Ruby 7. PHP
15. Data processing/ETL Pipelines WebHooks APIs Real time file processing Common use cases
16. Let’s Code!
17. Ibadan Random Number Generator
18. Steps 1 1. Create Google Cloud Account 2. Login to the Console 3. Create a project 4. If this is your first time, you might need to setup a billing profile and input your card details 😟 5. Go to “Cloud Run” 6. Add a service a. Select runtime(doesn’t have to be NodeJS) b. Give the function a name c. Keep the defaults 7. It might take some time to create, it’s fine. 8. Study/Absorb the environment - focus on source. 9. Deploy and test 🚀
19. Steps 2 1. Download zip 2. Extract and open in code editor 3. Install & setup google cloud CLI - gcloud. 4. Instructions at: https://cloud.google.com/sdk/docs/install 5. Add extra endpoint 6. Ensure you’re in the right project a. “gcloud config set project <project-ID>” 7. Modify code 8. Run deploy: a. gcloud beta run deploy random-number-generator-func --source . --function "helloHttp"
