The blog post "Azure SLA (Service Level Agreement): Explained" on Arnav Sharma's website provides a detailed explanation of Microsoft Azure's Service Level Agreements. These SLAs are crucial for customers as they guarantee the availability and uptime of Azure services like virtual machines, app services, and databases. The post breaks down the SLA percentages and their corresponding allowable downtime, ranging from 99% (with an annual downtime allowance of 87.6 hours) to 99.9999% (with just 31.5 seconds of annual downtime). It also covers the varying SLAs for different Azure services, such as 99.9% for single instance virtual machines using premium storage and 99.95% for virtual machines in the same availability set or zones. The article emphasizes the importance of understanding these SLAs for effective use of Azure services, including the calculation of combined SLAs for interconnected services and the differences in SLA levels between premium and free services. Additionally, it discusses the compensation available to customers through service credits in case Azure fails to meet its SLA commitments.
