SLA services are based on service-level agreement. It is a contract between the service provider and the customer. It basically defines the service level that the service provider will offer. It explains what the customer will be receiving but not how the offered services will be provided.

SLA-based services come in three different categories: SLA cloud services, SLA telecommunication services and SLA managed services.

SLA cloud services are agreements that ensure users of cloud services receive minimal service level. They give assurance to businesses that the service will be reliable and responsive.

SLA telecommunication services are concerned with enacting rules that control the delivery of telecommunication products to the end-user. They also define how the quality level for the services will be measured and monitored.

SLA managed services dictate what level of managed IT services a business will receive. These services are essential for businesses as they need reliable IT support.

Now, before you decide which service to use, you must consider a few factors:

The uptime of the services

The time it takes for the provider to respond to a request or problem

The time it takes for an issue to be resolved

The level of security provided to the customer
