There are two options for updating the OS. One is an update management solution that launches the Azure Portal, and the other is using the OS's upgrade solution.
# Upgrade by Azure Portal
Azure have provided a complete Automatic upgrade solution (opens new window)
- Login Azure Portal, Click the "Update management" on Operation section, then "Enable" it
- Wait for minutes and the Azure will create an update solution. Click "Schedule update deployment" to start set update policy
# Upgrade by OS
Upgrade by OS is implemented by logging in to the VM and inputting an update command or an operation update function, which is different from the update management function of the Azure portal.
# Linux Upgrade
Linux OS update, you only need to run an update command to install most updates
#CentOS or Redhat sudo yum update -y #Ubuntu apt update && apt upgrade -y
In fact, the image provided by Websoft9 has periodically executed the above update commands through cron of Linux.
# Windows Upgrade
The update of the Windows server is similar to that of the local computer. Manually find the update management program and set the automatic download automatic update.
