Co to jest Serverless Architecture?

Serverles architecture does not mean there are no servers - it means that developers no longer need to o provicon, configure, scale, or maintain servers. The cloud providera er automatically handle these tasks, dynamically allocating compute resources in responsie te to docud. This model allows teams to focus exclusivele on writering core and defineg definess contributes logic, while the infrastructure layer becomes an invisiblee, elastic utity.

Key criterics of serverless computing include:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Event- drift execution Xi1; Xi1; FLT: 1 Xi3; Xi3; - code runs only when triggered by y specific events such as HTTP requests, database changes, or message arrivals.

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Stateless execution Xi1; Xi1; FLT: 1 Xi3; Xi3; - each function invocation is typically stateless, promoting clean separation of concerns andd horizontal scalability.

Funkcje Azure: The Compute Powerhousie

Azure Functions is an event- propern, serverless compute service that lets you executute code written in a variety of languages - including C #, JavaScript, Python, Java, and PowerShell - in responsie te to o triggers. Functions can be used te o build web API, process file uploads, react to database changes, schedule batch jobs, or integrate with cloud services.

Wdrożenie Combinad Serviless Solution

While Azure Functions and Logic Apps can be use independently, they shine when combined. A typical Pattern is to use an Azure Function to perfom a specific compute task - such as processing an image, validating data, or calling a third- party API - and then us us a Logic App to orchestrate multiple functions and services into a cohesivy ente.

Egzamin Architecture: Order Processing Pipeline

Consider an e-commerce system where orders are placed via a REST API. The flow could be:

  1. Xi1; Xi1; FLT: 0 Xi3; Xi3; HTTP trigger Function Xi1; Xi1; FLT: 1 Xi3; Xi3; receives the order JSON and validates it against Xionss rules (np., check inventory via a database call).
  2. If valid, the Function writes the order to an Azure Queue Storage or Event Grid topic.
  3. Reference 1; Xi1; FLT: 0 X3; Xi3; Logic App XI1; Xi1; FLT: 1 XI3; XI3; is triggered by the queue message. It retrieves the order details, calls a customer services Function to calculate tax (anotherr Function), then uses a connector to posto the order to the ERP (e.g., Dynamics 365).
  4. Finally, the Logic App sends an order confirmation email via Offices 365 andd logs thee transaction to a SQL database.

This architecture separates concerns: compute logic lives in Azure Functions, while te e orchestration and integration logic live in Logic Apps. Each contesent can be developed, tested, and scaled indepently.

Begt Practices for Combinaing Both Services

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Stateless Functions, Stateful Logic Apps Xi1; Xi1; FLT: 1 Xi3; Xi3; - keep Functions stateless; use Logic Apps to manage state (np., readies, waiting for human input).
