In this hands-on training, you will gain the knowledge to write, test and deploy Cloudflare Workers. You will understand the tools available and how to accomplish common Production activities such as error logging, secrets, and automating your deployment across different environments. You will understand how this tool can better cater to business cases better than AWS Lambda or Google Functions; while being cheaper and more available than AWS Lambda Edge and its counterparts in Google and Azure.
If you are entering the Serverless world, then this is an excellent course for you.
If your web product needs to be rapidly available to your customer across the world, the Cloudflare platform has more presence than any other offering out there. The same goes for your logic and your data. This is where Cloudflare Workers shine.
During the last 10 years, I have guided 45+ product development teams from ideation to release of web applications. I've guided the small three do-it-all devs and the large project with 75+ individual contributors distributed across six time zones and ten different teams. Each product in its particular stage was chasing different goals.FAQ

Is this course useful for a beginner in frontend or nodejs development?
If you are starting on your development career, the Cloudflare workers add unnecessary complexity to your learning context. The same would apply if you were learning nodejs and doing it via AWS Lambdas or Google Functions.
