Use Azure Function to Schedule Auto Start for VMs

VMs on the Microsoft Azure platform can be configured to automatically shut down by schedule. However, currently only VMs in the DevTest Lab service can be powered on automatically. Regular VMs have not been updated with the auto start capability. But still, we can take advantage of Azure Function V3 and PowerShell Core to start the VM by timed schedule.

At least four community friends have used the system to deploy their own blogs on Azure and Alibaba Cloud.

Performance Optimization for My .NET Core Blog on Azure

I rewrote my blog system with .NET Core last year. After more than a year of optimization, the server response time is now 8ms comparing to 80ms when it first went live. This article shares what I have done to make my blog works really fast. In fact, before .NET Core, my old blog system was written by .NET Framework, built from ASP.NET Web Form 2.0 in 2008 all the way up to ASP.NET MVC5 in 2018. …
