This document discusses serverless computing and compares it to traditional server-based computing. Some key points: - Serverless allows for inherent scalability, cost savings since customers only pay for resources used, and lower latency since code can execute near users. However, testing/debugging is more difficult and vendor lock-in is a risk. - Serverless is compared to IaaS/PaaS/SaaS models, with serverless being akin to "buying a plane ticket and flying" rather than owning/renting infrastructure. - Popular serverless options like Python and JavaScript Azure Functions are discussed, along with benefits like auto-completion, independent IDE usage, and ease of cloud integration and deployment.

Serverless
- 1. Serverless By : Vishwas Narayan
- 11. So before get to know ● API and Rest API ● OPS ● TOPS ● Server Side Scripting ● How an API works? ● What is the function of the entire system that you want to implement as there are many services.
- 12. Why serverless is more handy ● Scalability is inherent in serverless designs. ● Developers are only charged for the server space they utilise, which saves money. ● Code may be executed closer to the end user, reducing latency. ● It is feasible to deploy and upgrade software quickly. ● There is no need for server administration.
- 13. Cons of the Serverless ● Testing and debugging become more difficult. ● Serverless computing raises new worries about security. ● Serverless architectures are not intended to support long-running operations. ● Performance may suffer as a result. ● The possibility of vendor lock-in exists.
- 14. This or that all still remain same for the purpose V/S V/S
- 15. We all have a problem to solve?
- 18. How to solve it?
- 19. How to solve it?
- 20. How to solve it?
- 21. So let's just compare to the Cloud? Buying a plane is - IaaS/VM Renting a Plane is - PaaS Buying a plane ticket and flying is - Serverless
- 22. So now why is it priced the way it is priced? So there are multiple reasons for it: We cna list some of them here(well actually I am Listing some so listen if you have any thing to say then ping me later)
- 23. Choice of Language C#,java,javascript,python and powershell is also available..
- 24. Python Azure Function ● It is entirely open source. ● First-rate interaction with Visual Studio Code and the CLI Trigger Python code from a variety of sources. ● Scale and cost for serverless computing ● Monitoring in real time using Azure Application Insights, ● Set up continuous integration and delivery (CI/CD) with Travis CI, Azure DevOps, and other tools.
- 25. Rich Intellisense and Easy Cloud Integration ● They are nothing but easy auto fills and deployment of the code. ● It's independent of the IDE(Integrated Development Environment) that we are using. ● This is “Pro” of the Technology today.
- 26. We need to do some installation prior on bare metal OS If you are a beginner we will be doing the Visual Studio Code (all our demos happen with this only and sometimes visual studio community edition) https://code.visualstudio.com/ .NET Core 3.1 (LTS is what I prefer) .NET Tutorial | Hello World in 10 minutes (microsoft.com) The live channel that i would love you all to see: .NET Live TV | Live developer streams every day (microsoft.com) VSCode Azure Functions extension : I prefer azure tools(I will show this) Azure Functions Core Tools Work with Azure Functions Core Tools | Microsoft Docs
- 27. We need to do some installation prior on bare metal OS If you are a beginner we will be doing the Python interpreter from the python.org Nodejs from the nodejs.org And if you need any more you can do it.
- 28. Some commands will still remain same relate to some projects or the software 1. func init 2. func new 3. func start 4. func deploy 5. func publish
- 29. Some VS Code Shortcuts ● ctrl + ` - Command prompt in the VS Code ● Code . - For opening the VS Code ● ctrl+shift+P - Command Pallet
- 30. So let's go and
