Tutorial / Cram Notes
Service Level Agreements, or SLAs, are a crucial aspect of any managed service arrangement, including cloud services such as those offered by Microsoft 365. An SLA is essentially a contract between a service provider and the end user that clearly states what levels of service are guaranteed and what compensations are provided should those services not achieve the specified levels.
Uptime Principles
Uptime is one of the most critical components of an SLA, particularly in the sphere of cloud services like Microsoft 365. It refers to the amount of time a service is available and functional. Uptime is typically expressed as a percentage, such as 99.9% (“three nines”), indicating how much time in a year, month, or other periods the service is expected to be available. For example, Microsoft 365’s SLA might guarantee 99.9% uptime, translating to a permissible downtime of around 8.76 hours over a year.
Service Credits for Refunds
In the event that a service provider like Microsoft 365 does not meet the promised uptime, they might offer service credits as a form of compensation. These are not direct monetary refunds but rather credits applied to the customer’s account, effectively reducing the cost of the service for subsequent billing periods. The amount of service credit is often scaled depending on how much the actual level of service fell short of the promised SLA.
For instance, Microsoft might provide a 25% service credit if uptime falls short below the guaranteed 99.9% but stays above 99%. If uptime drops below 99%, the credited amount might increase to 50%.
SLA Tiers
SLA tiers are different levels of service that are offered, sometimes at different pricing points. Each tier might guarantee differing levels of uptime, support response times, and other performance metrics. In the context of Microsoft 365, the following could be hypothetical tiers:
SLA Tier | Guaranteed Uptime | Support Response | Scheduled Maintenance |
---|---|---|---|
Basic | 99.9% | Within 24 hours | Yes (with notice) |
Standard | 99.95% | Within 8 hours | Limited (with notice) |
Premium | 99.99% | Within 2 hours | Minimal |
Roles and Responsibilities
The delineation of roles and responsibilities within an SLA is fundamental to ensuring that both the service provider and customer understand their obligations. The service provider’s duties typically include delivering the service to the promised standard, communicating effectively with customers about any service downtime or maintenance, and delivering any compensation owed.
Customers also have responsibilities such as using the service as per agreed terms, notifying the service provider in the event of a service disruption, and ensuring their systems are adequately secured on their end.
Microsoft 365 SLAs also outline what is not covered under the agreement. This can include downtime resulting from a customer’s misuse of the service, issues stemming from third-party services or software, or exceptional circumstances that are beyond the control of the service provider, like natural disasters (commonly called “Force Majeure” events).
To summarize, SLAs form the backbone of trust and reliability between cloud service providers like Microsoft 365 and their customers. Understanding the details of an SLA, including uptime guarantees, compensation mechanisms like service credits, various service tiers, and clearly defined roles and responsibilities, is essential for the effective use of cloud services. With a comprehensive SLA, customers can make informed decisions and align their expectations with the value proposition offered by the service provider.

A) Bronze, B) Gold, C) Silver, D) Diamond, E) Custom
SLA tiers often include levels like Bronze, Silver, Gold, and Diamond, as well as the possibility of Custom SLA tiers for different levels of service.
True or False: SLAs usually only include technical details and do not cover any business aspects.

SLAs typically cover both technical and business aspects of service, including roles, responsibilities, and service credits.
Single Select: Who is primarily responsible for defining roles and responsibilities in an SLA?
- A) The customer
- B) The service provider
- C) Both the customer and service provider
- D) A third-party auditor
C) Both the customer and service provider
Defining roles and responsibilities is a mutual agreement between the customer and the service provider in an SLA.
True or False: Uptime guarantees typically include both scheduled and unscheduled maintenance periods.
- False
Uptime guarantees often exclude scheduled maintenance periods from the uptime calculations, as these are planned outages.
In the context of SLAs, what are service credits?
- A) A discount offered on future purchases
- B) Financial compensation given to customers for not meeting service levels
- C) Bonus features added to the user’s account
- D) Credit points for a customer loyalty program
B) Financial compensation given to customers for not meeting service levels
Service credits are a form of financial compensation to the customer when the provider fails to meet agreed SLA levels.
True or False: All SLAs are standardized and identical across different service providers.
- False
SLAs vary between service providers and are tailored to specific services and customer requirements.
