Building Lambda functions in Rust
15In this video, we're diving deep into real-world challenges, starting with why Rust is great for Lambda functions and how it can save you money. We'll tackle the task of automating tag lists for restaurant menus, moving from Python to Rust for better performance.
In this part, we're getting hands-on with deploying our Rust Lambda function to AWS. We'll talk about the different ways to do it and why we chose the Cargo Lambda toolkit. Despite a few bumps along the way, we'll guide you through the deployment process, even touching on the use of Zig for cross-compilation.
As we move forward, we'll explore SAM (Serverless Application Model) for deploying Lambda functions, sharing practical tips on creating SAM templates and deploying with SAM CLI commands. Join us as we troubleshoot issues, discuss packaging choices, and explain the impact on performance.
Wrapping things up, we'll have a chat about the ups and downs of deployment, with some laughs along the way. We want to thank all our viewers and invite you to subscribe to our YouTube channel for more useful content. Stick around as we plan to visit another streamer's channel for more coding fun!
