Now days with the adoption of Serverless architectures, microservices are becoming a great way to breakdown problem into smaller pieces. One situation that is common to find, is multiple backend services running on technologies like NodeJS, Python, Go, etc. that need to be accessible via HTTPS. It is possible to enable these internal microservices directly with SSL over HTTPS, but a cleaner approach is to use a reverse proxy that front ends these microservices and provides a single HTTPS access channel, allowing a simple internal routing.
In this blog, I am showing how simple it is to create this front end with Nginx and leveraging “Let’s encrypt” to generate trusted certificates attached to it, with strong security policies, so that our website can score an A+ on cryptographic SSL tests conducted by third party organizations.

Recently, I was challenged at work, to make my drone take off, using a simple voice command via “Alexa”. Given this challenge came from my boss, I decided to happily accept it. I ended up writing some simple NodeJS code that interfaces with my drone and used a series of new Echo skills and a Home Assistant bridge to easily command my drone to take off and follow simple orders, something like “Alexa, please take off my drone and make it back flip twice“.
After some hours and many coffees, I got to the point that I was done and ready to show my working demo. However, I needed to take my NodeJS code and put it somewhere in the cloud to run it. I had a few options, like deploying my code into Oracle Application Container Cloud Service, which runs NodeJS natively over docker containers, but given that I have done this in the past and I was in an “adventurous mode”, I decided to try something new.
I wondered how simple would it be to use Bitnami to spin up a new NodeJS VM in Oracle Public Cloud… Well, I was amazed how pleasant the experience was, so I decided to capture this excitement in a quick blog for you to try as well.
