I recently needed to run a simple Python script every 10 mins to alert me if a website had been updated, rather than going the traditional route of spinning up a VM with a cronjob running on it I wanted to investigate using a serverless approach. In this guide I'll show you have to setup a Google Cloud Function and Cloud Scheduler using Terraform.
GPS ephemeris data is used by your GPS devices (smartphone, GPS running watch, camera with built in GPS tagging etc.) to predict which satellites will be in the sky at a particular point in time. Knowing which satellites are available dramatically decreases the amount of time it takes for your device to get a GPS "fix". The prediction data is usually valid only for a few days so new data needs to be downloaded from the internet periodically.
I've recently started using Docker for my development environment. One of the first problems I ran into was how to run multiple Docker Compose microservice projects on the same host if they all need to run on the same port (port 80 for example).
I will outline one of the solutions that involves using Nginx as a reverse proxy to send requests to the correct backend microservice.
AWS Elastic Beanstalk (EB) is an AWS service that lets you automatically deploy load balanced PHP applications to EC2. One of the lesser know features is the ability to setup EB as a worker to handle long running or computationally intensive tasks (Think image processing/bulk mail sending etc.). EB Workers listen to a SQS queue and automatically run any jobs you put onto the queue. In this post I'll show you how to setup your own EB PHP worker.
