By default, the Virtuozzo Update Services (VUS) component is configured during the Virtuozzo Containers 4.0 installation on your Hardware Node to download Virtuozzo Containers updates from the Virtuozzo Update Center (accessible at http://vzwinupdate.swsoft.com). However, if you have more than one Hardware Node in your network, you may wish to set up a special local VUS server that will automatically download and store the latest Virtuozzo Containers updates from the Virtuozzo Update Center and to configure VUS on your Nodes to obtain updates from this server. Deploying a local VUS server in your network brings the following advantages:
- You can greatly save bandwidth on the Internet connection since you download available updates from the Virtuozzo Update Center to the local VUS server only once and all Hardware Nodes obtain the updates directly from the VUS server in your local network.
- You can lock the downloaded updates on the local VUS server for the time needed to validate these updates against their compatibility with your working environments. This ensures that only those updates will be deployed on your production Hardware Nodes that have been thoroughly tested and approved by your IT department.
- You do not need to have all your Hardware Nodes connected to the Internet in order to get the latest Virtuozzo Containers updates. Only the local VUS server must be directly connected to the Internet to obtain available updates from the Virtuozzo Update Center.
