Azure Service Level Agreements (SLAs)

Overview

Azure Service Level Agreements (SLAs) outline the performance standards and uptime guarantees that Microsoft commits to for its Azure services. SLAs ensure that your applications and services remain highly available and reliable, providing peace of mind and enabling you to meet your business requirements.

Core Functionality

Uptime Guarantees

• High Availability: Microsoft guarantees a certain level of availability for Azure services, typically expressed as a percentage (e.g., 99.9% uptime).
• Service Credits: If Azure services do not meet the SLA uptime guarantees, Microsoft offers service credits to compensate for the downtime.

Performance Standards

• Latency: Specifies the maximum allowable response time for Azure services to ensure optimal performance.
• Throughput: Defines the capacity and processing power of Azure services to handle workloads efficiently.

Service Monitoring

• Continuous Monitoring: Microsoft continuously monitors Azure services to ensure compliance with SLA standards.
• Incident Management: In case of service disruptions, Microsoft promptly addresses and resolves incidents to minimize impact.

SLA Documentation

• Individual Services: Each Azure service has its own SLA that specifies the uptime guarantee, performance standards, and service credits.
• Composite SLAs: When using multiple Azure services together, the overall SLA is calculated based on the individual SLAs of each service.

Well-Architected Framework Considerations

Cost Optimization

SLAs help you plan and budget for potential downtime by providing clarity on service reliability and compensation for non-compliance.

Operational Excellence

SLAs drive continuous improvement by ensuring that Azure services meet high performance and availability standards, reducing operational risks.

Performance Efficiency

By adhering to SLA performance standards, Azure services ensure optimal performance, enabling your applications to run smoothly and efficiently.

Reliability

SLAs enhance the reliability of your applications by providing clear expectations and guarantees for service availability and performance.

Security

While SLAs primarily focus on availability and performance, they also ensure that Azure services operate within secure and compliant environments.
