Experience
Kubernetes Cluster and Pixel Streaming
Scaling was important as the machines required for the experience were about 1,000 USD per month due to the NVIDIA card, G5 instances type.
I automated the creation of Windows machines that would do Pixel Streaming. Also, I configured Auto Scaling groups to use these streaming machines to deliver A+ graphical experience for the users connected to them. The project was a meta-verse-like experience.
Everything was managed by terraforming.
Stack: Node.js, Redis, Postgres, React, Unreal Engine, etc
Infra: Kubernetes, Auto Scaling groups, S3, Cloud Front, Terraform, etc.
Kubernetes Cluster for Blockchain
https://taraxa.io/After the migration, we needed to scale our testnet and mainnet to around 150 nodes and around 1.2 TB of RAM (distributed globally). The biggest Kubernetes cluster had around 800 GB of RAM.
We used FluxCD for GitOps, and I've also migrated from Jenkins to CircleCI.
Developed a script that helped outside users run a node of our blockchain at most clouds.
The great about the project is that it is open source.
