Let's Build It: URL Shortener in .NET
Learn how to build a production-ready URL Shortener in its entirety, including conception, development and deployment.
About This Course
In this massive "Let's Build It" course, Gui Ferreira will build an entire, production-ready
URL Shortener system from conception to production deployment. The course will start with
requirement analysis, move into system design, and then follow that up by setting up a development
environment and continuous integration. It will then move to infrastructure as code and secrets
management, and only after all the setup has been done properly will it move into coding an entire
URL shortener using best practices. On top of that, the author will develop a client-side web
application that will include best practices for telemetry and security. This is a unique opportunity
to learn how a system can be built from scratch all the way to production.
