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

Platform for Scalable Web Apps | How I built my website with Kubernetes

I'm confused. Watch till the end of the video.

Occasionally I work on a project only to scrap it so I wanted to show you one example. From the outside it may appear that a developer is some genius guy who can make whatever he wants. Although this is partially true (engineering is magic), many of you don't see all of the time spent just thinking and reading... All of the footage I capture is usually the by-product of countless hours of thinking. Over the past month I've worked on many new things - react, I2C driver programming and containerization with docker. It's just reminded me how large the technology stack is and everyone is a beginner at some level of the stack. I feel like I haven't made much progress in the past month because I've been a beginner at a lot of new things :) This is the reality and I needed a YouTube vid so I figured I would talk about it.

The Reality of Programming

In 2019 I wanted to teach myself product development while filming the whole process. It took a lot longer than expected and I burned out pretty hard near the end(2021). 

And yes I was doing it all myself which I now know is not very smart, it's just too much for one person. You really need a team of people to bring a product to market, or at least a few founders. I guess this was more of a learning experience than anything else. I knew I needed to gain experience in commercialization as my normal builds were quite sketchy. So it was good to try and build something solid over long periods. 

These first 5 months included a lot of electrical hardware design(PCBs) and embedded software development. I do want to catch you guys up on everything so I'll be making videos in roughly 5-month chunks between 2019-2022. Until we get more up-to-date, I think it just makes the most sense to post the footage in order.
