Prevent server overload with Cloud Load Balancers
One way that you can prevent a server from becoming overloaded is to use the Connection Throttling feature of Cloud Load Balancers. Connection throttling limits the number of simultaneous connections that are allowed from each IP address. This feature helps prevent malicious or abusive traffic from reaching your server and its installed applications.
This procedure assumes that you’re working with an existing load balancer. If you don’t have a load balancer yet, follow the instructions in the article Configure a load balancer to create one.
Configure connection throttling
Use the following steps to configure connection throttling for your load balancer:
- Log in to the Cloud Control Panel.
- In the top navigation bar, click Select a Product > Rackspace Cloud.
- Select Networking > Load Balancers.
Click on the gear icon next to the load balancer that you want to configure, then select Edit Connection Throttling from the menu.
The following pop-up window appears:
Enter a value between 1 and 100000 for Max. Connections.
- Click Save Connection Throttling.
