  • Kubernetes has proven itself a valuable ally for the reliability sought for business critical applications. At time of writing, we have 70+ pods deployed in 2 clusters. The pods consist of everything from ASP.Net Core to Redis.
  • From the start of serverless technology's existence, I have whole heartedly embraced the cutting edge of the technology. In this effort, Azure Functions V2 (.Net Core 2.0) are one of the primary vehicles for our software and provide the data processing and simple APIs.
  • ASP.Net Core in combination with Entity Framework Core make a beautiful, easy to create, and performant solution to Sites and APIs, with piles of middleware to boot.
  • React combined into ASP.Net Core (or deployed separately for simple sites like this one) gives all the interactivity to the interface one could desire. I have found layering TypeScript over React makes the code much, much less error prone.
  • Azure DevOps has saved me countless hours of deployments by automating everything. Since we use GitOps for our configuration, everything is is handled automatically, soup to nuts.
