Summary of "Week 4 Lab: Serverless Compute Services (AWS Lambda/Azure Functions)"

Overview

The video provides a detailed guide and explanation for the Week 4 lab exercise focused on Serverless Compute Services, specifically AWS Lambda and Azure Functions, which are key components of modern cloud computing trends.

Key Technological Concepts

Serverless Computing: A cloud computing model where developers write and deploy code without managing servers, installations, or system configurations. The cloud provider handles infrastructure management.
AWS Lambda and Azure Functions: Serverless compute services that allow users to write, test, and deploy code directly in the cloud using various supported programming languages.

Product Features and Usage

AWS Lambda

Access via AWS console by searching and selecting the Lambda service.
Create functions by choosing programming languages such as Python, NodeJS, Java, .NET, C, Go, Ruby, etc.
Supports custom runtimes for languages like C++.
Provides a code editor and testing environment directly in the cloud.
Input and output are handled in JSON format.
Users can run various types of problems such as simple arithmetic, string manipulation, array processing, and sorting.
Logs are available to check execution time and performance metrics (logs appear after a few minutes).

Azure Functions

Accessed by creating a Function App resource in the Azure portal.
Supports multiple development options: VS Code, CLI, or portal-based development (portal recommended for ease).
Similar language support and JSON input/output format.
Requires unique function names.
Enables writing and testing of similar problem types as AWS Lambda.

Lab Exercise Guidance

Practice writing and executing various programs, including:
- Basic “Hello World”
- Arithmetic computations
- Looping problems
- String manipulation
- Array operations (including multiple array inputs)
Analyze performance by reviewing logs to understand execution times across different languages.
Explore building simple web applications using these serverless platforms.
Emphasizes the importance of hands-on practice to familiarize with serverless environments.

Importance and Industry Relevance

Serverless computing is highlighted as a current and emerging trend in cloud computing.
Knowledge of AWS Lambda and Azure Functions is critical for future projects and real-world cloud application development.
The lab aims to provide foundational skills in serverless function development and deployment.
