Platform for Scalable Web Apps | How I built my website with Kubernetes
I’ve spent months building a platform to support my development of scalable web applications. In this video, I try to share the learning process.
My personal website has a lot behind the scenes that most people cannot interact with. I’ve written up a few microservices and decided to deploy them on kubernetes. Some may say that what I’ve done is overkill – but it really does simplify the workflow once its setup (and I don’t have to rewrite my codebase in the future!)
The end result:
– Kubernetes cluster on digital ocean.. 3 nodes, a load balancer, and persistent volume
– nginx-ingress controller exposes services to the outside world (all other services are internal)
Microservices:
– jwt authentication server (security)
– hangfire background processing server
– MySQL database
– mailer
– front end
There is still a lot of work to be done. While most services are scalable – the database is not. Currently, our database is a single instance. I think someday I will need to deploy a MySQL cluster to support replication, etc. This was a massive topic to cover in a single video so I could not explain everything, my hope is that people can take what they see and research further.
Technologies Used:
– CPU Intensive Backend: C# with ASP .NET Core
– Simple I/O Intensive Backend: Node js
– Database: MySQL
– Scheduler: Hangfire open source background processing library
– Authentication: JWT backed by Dotnet Identity
– Mailing Service: Sendgrid
– Integrations: YouTube, Github
– Deployment: Docker images w/ Kubernetes
– Front end: Next js / React
