How to Block a Request in a Proximity Server

In this episode of Running in Production, Filipe Névola goes over building a hosting platform for Meteor apps. It’s hosted on AWS with ECS and has been running in production since 2015.

Filipe talks about building critical services with Go, using Meteor to build front-end web dashboards, the importance of monitoring, using Recurly for subscription payments, multi-region AWS hosting and overall providing a highly available platform for thousands of clients.

Support the Show

This episode does not have a sponsor and this podcast is a labor of love. If you want to support the show, the best way to do it is to purchase one of my courses or suggest one to a friend.

• Dive into Docker is a video course that takes you from not knowing what Docker is to being able to confidently use Docker and Docker Compose for your own apps. Long gone are the days of "but it works on my machine!". A bunch of follow along labs are included.

• Build a SAAS App with Flask is a video course where we build a real world SAAS app that accepts payments, has a custom admin, includes high test coverage and goes over how to implement and apply 50+ common web app features. There's over 20+ hours of video.
