With Colosseum's virtual private data center product it is easy to create new virtual machines at the drop of the hat from our vast template library or by creating your very own unique template. But what you can also do just as quickly is create a load balanced cluster of VMs to serve content for you. With our load balancers you have 2 options:
- Load balancing clusters
With this option, you specify which VMs (nodes) will participate in a load balancing cluster. Incoming traffic is distributed evenly between all the VMs added to a cluster – you still present a single host name to end users, but they actually access the cluster of VMs rather than a single end point. This helps application availability: if one VM fails, traffic is automatically routed to another in the cluster. You can add and remove cluster VMs as required.
- Virtual Machine Auto-scaling
VM Auto-scaling increases or decreases your VM capacity by automatically adding or removing nodes to a cluster. The cluster is scaled in (decreased) or out (increased) based on rules you specify in the Control panel. For instance, you can create a rule that will add 3 more nodes to a cluster if CPU usage has been more than 90% for the last 5 minutes; or rules that remove a node if there has been more than 256 MB RAM free for the last 20 minutes.
