DIFFERENT TYPES OF SERVICE LEVEL
AGREEMENT
Page - 4
There are three types of Service Level Agreement
Customer Based SLA
Service Based SLA
Multilevel Based SLA

CUSTOMER BASED SERVICE LEVEL AGREEMENT
Page - 5
This type of agreement is used for individual customers and
comprises all relevant services that a client may need while
leveraging only one contract. It contains details regarding
the type and quality of service that has been agreed upon.
For example, a telecommunication service includes voice
calls, messaging, and internet services, but all exist under a
single contract.

SERVICE BASED SERVICE LEVEL
AGREEMENT
Page - 6
This SLA is a contract that includes one identical type of
service for all of its customers. Because the service is
limited to one unchanging standard, it is more
straightforward and convenient for vendors.
For example, using a service-based agreement regarding an
IT helpdesk would mean that the same service is valid for all
end-users that sign the service-based SLA.

MULTILEVEL SERVICE LEVEL AGREEMENT

This agreement is customized according to the needs of the
end-user company. It allows the user to integrate several
conditions into the same system to create a more
convenient service.
This is further divided into three categories
 Corporate level
 Customer level
 Service level

MULTILEVEL SERVICE LEVEL AGREEMENT
Page - 8
 Corporate level: This SLA does not require frequent
updates since its issues are typically unchanging. It
includes a comprehensive discussion of all the relevant
aspects of the agreement and applies to all customers in
the end-user organization.

MULTILEVEL SERVICE LEVEL AGREEMENT
Page - 9
 Customer level: This contract discusses all service issuesthat
are associated with a specific group of customers. However, it
does not take into consideration the type of user services.
For example, when an organization requests that the security
level in one of its departments is strengthened. In this
situation, the entire company is secured by one security agency
but requires that one of its customers is more secure for
specific reasons

MULTILEVEL SERVICE LEVEL AGREEMENT

Service level: In this agreement, all aspects attributed to a
particular service regarding a customer group are included.

PRICING IN SERVICE LEVEL AGREEMENT
Page -11
Service Level Agreements are based on the usage model and a
subscription based model. Most cloud providers price their pay-as-you-go
at a premium and issue standard SLA’s only for that purpose. But the SLA’s
attached to a subscription often offer different terms . Like if any
organization requires access to a certain level of resources then they
require subscriptions for services. This is because a pay-as-you-go model
may not provide that level of access under peak load conditions.
