SLA definition - define SLA
"SLA - A promise of maintaining a consistent level of data transfer over a network. Every ISP typically has an SLA that states the promise of data availability that the ISP will provide for its customer. Usually SLAs are only given to business customers that pay more for their connections than home users; thus business connections are typically more reliable, and also cost more. SLAs are very important for companies that can lose millions of dollars when their customers cannot access their webservers."
