SLAs for Core Azure Services 3 – Microsoft AZ-900 Exam

Real-world Examples of Core Service SLAs in Action

Let’s consider some hypothetical scenarios to see how Azure’s SLAs would come into play:

  1. Scenario – VM Downtime: Imagine a business that operates critical workloads on a single Azure VM. If this VM experiences downtime that exceeds the 99.9% availability guaranteed by Azure’s SLA, the business may file a claim for service credits. If, however, the VM was part of an availability set with multiple VMs, and the downtime was not system-wide but affected only one instance, the SLA may not be considered breached.
  2. Scenario – Database Connectivity: If a company using Azure SQL Database encounters a connectivity issue that affects the availability of their databases below the SLA threshold of 99.99%, they may be eligible for service credits. The business must provide evidence of the outage and show that it affected their operational capability.
  3. Scenario – Network Outage: In the event of an Azure networking issue where the virtual network’s availability drops below 99.99%, organizations reliant on this service for their operations may seek compensation through service credits.

Conclusion

SLAs for Azure’s core services form a fundamental part of the contractual agreement between Microsoft and its customers. They set the expectations for service availability and performance and provide recourse in the form of service credits when those expectations are not met. Understanding these SLAs is essential for any organization operating in the cloud as it affects how they architect their solutions, manage their risk, and ensure business continuity.

However, it’s important for businesses to go beyond the SLA and create their own robust disaster recovery and business continuity plans. Relying solely on service credits may not be sufficient to mitigate the operational and reputational damage that can occur from service outages.

In sum, SLAs are an integral part of leveraging Azure’s core services. They assure customers of a minimum level of service quality and responsiveness that is backed by financial guarantees, helping businesses to trust and rely on Azure’s cloud infrastructure for their critical operations.
