- Cloud Solution Providers
Usually Microsoft partners that organization hire Customers pay CSP directly for services
Factors that Affect Costs
- Resource Type
Because Azure costs are resource-specific, the usage that Azure tracks will depend on the resource type
- Service
Azure usage rates, and billing periods, will sometimes differ between Enterprise, Web Direct, and CSP customers
- Location
Because Azure infrastructure is globally distributed, there will be instances where usage costs vary between locations.

Service Level Agreement
SLAs are formal documents that detail the performance standards that apply to Azure products and services
There are separate SLAs for many individual Azure products and services
SLAs also define performance standard AND what happens if a service or product fails to meet the designated availability commitments
Performance targets are outlined in Service Level Agreements
Performance-targets range form 99.9% to 99.99%
Service Level Agreements also describe how Microsoft will respond in the event of an Azure product or service failure that results in a missed SLA
does not offer SLA for free products
Application SLAs
Azure customer can use Application SLAs to evaluate how their own Azure solutions are meeting their business requirements
When you crate an Application SLA, you should identify workloads that the SLA will apply to, and you should plan for usage patterns
Because usage patterns of your solution will play a role in the SLA requirements that you define, you should identify differences in requirements during critical & non-critical periods.
On the flip side, you should minimize costs during non-critical periods by running the application in a single region
