Resource-limiting on the Virtual Private Server
A look at the current and future direction of resource-limiting in FreeBSD Jail
This session will discuss what server resources can or should be limited on a virtual server. It will also focus on what techniques Verio implements in order to keep multiple users on a single physical server from adversely affecting each other. For example, some resources such as CPU, Disk-I/O and Network Bandwidth should be enforced with artificial limits in order to prevent disruption amongst users.
Through real-life examples, attendees will learn from a leading player in the hosted services industry techniques on managing multiple users on the same physical server. Through a practice known as “shaping,” multiple users can remain on the same physical server with reasonable bursting for short term high resource consumption. Compared to fixed static limits, “shaping” is much more satisfying to the user and in general actually lowers average server load and allows for greater densities. Attendees will also learn the relative merits and disadvantages of several limiting algorithms.
