What It Is
A service level agreement, or SLA, is the part of a provider’s contract that sets measurable commitments. For hosting, that usually means a minimum uptime percentage, how quickly support will respond, and how fast failed hardware will be replaced. It also explains what you get if they miss those targets, usually a credit on your bill. Think of it as the warranty card that comes with a service.
Why It Matters for Your Business
An SLA turns marketing claims into something you can hold a provider to. If your online store depends on being available, the difference between a strong SLA and none at all matters. A business that loses a day of sales during an outage can at least claim the promised credit and has clear grounds to switch providers if outages keep happening.
Good to Know
Read what the SLA excludes, not just what it promises. Scheduled maintenance, problems caused by your own code, and attacks are often left out. Credits are usually small compared with your actual losses and must be requested within a deadline. Treat the SLA as a sign of how seriously a provider takes reliability, not as insurance.
