Running an ECS service without HTTPS is a security gap and a user experience issue. Adding an ALB with an ACM certificate gives you HTTPS termination, and ECS registers task IPs directly with the target group. TL;DR: Configure an Application Load Balancer with an ACM TLS certificate to expose an ECS service over HTTPS.Stack: AWS … Read more
Deploying to ECS by hand is fine once. After that, you need a pipeline. AWS CodePipeline with GitHub source and CodeBuild handles the full cycle: source change, build Docker image, push to ECR, deploy to ECS. TL;DR: Set up a CI/CD pipeline for ECS using AWS CodePipeline with GitHub and CodeBuild.Stack: AWS CodePipeline, CodeBuild, ECS, … Read more
Application Load Balancers work well for HTTP/HTTPS traffic, but when you need to handle raw TCP/UDP at high throughput with minimal latency, a Network Load Balancer is the right choice. It operates at Layer 4 and routes connections directly to target IPs without inspecting HTTP headers. TL;DR: Set up an AWS Network Load Balancer (NLB) … Read more
The Arduino Ethernet Shield turns your microcontroller into a network device. With it you can make HTTP requests, serve small web pages, or integrate Arduino sensor data into a larger system over the LAN. TL;DR: Connect an Arduino Ethernet Shield to a network and make HTTP requests or serve data from a microcontroller.Stack: Arduino, Ethernet … Read more
The DHT11 is a basic temperature and humidity sensor that outputs digital readings. It costs almost nothing and works out of the box with Arduino, but the library setup needs to be done correctly or you get garbage data. TL;DR: Connect a DHT11 sensor to an Arduino and read temperature and humidity using the DHT … Read more
Arduino is a microcontroller platform that bridges software and hardware. If you have never done embedded development, it is the fastest entry point: cheap boards, a simple IDE, and a massive library ecosystem. TL;DR: An overview of the Arduino platform: the board, the IDE, the basic program structure, and the essential concepts for getting started … Read more
Your Lambda function is slow and you have no idea which part is causing it. X-Ray traces each invocation, shows you service map connections, and breaks down where time is being spent. It is the difference between guessing and knowing. TL;DR: Add AWS X-Ray tracing to a Python Lambda function to get distributed traces and … Read more
