ISO/IEC 19086-2:2018/Amd 2:2025

Overview

ISO/IEC 19086-2:2018/Amd 2:2025 is the second amendment to Part 2 of the ISO/IEC 19086 series, which establishes a comprehensive service level agreement (SLA) framework for cloud computing. Specifically, this amendment updates the metric model, a key component in defining and measuring SLA parameters for cloud services. Developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), this standard ensures consistent and precise evaluation of cloud service performance through standardized metrics.

Key Topics

• Cloud Computing SLA Framework: Builds upon the fundamental SLA concepts introduced in Part 1, focusing on measurable parameters.
• Metric Model Enhancements: Specifies updated metrics for SLA components, enabling better quantification of cloud service quality and reliability.
• Technical References: Incorporates revised normative references, including ISO/IEC 19086-1, cloud computing vocabulary ISO/IEC 22123-1, and XML Schema Definition Language (XSD) 1.1, to support the metric framework.
• Terminology and Definitions: Clarifies terms and concepts aligning with updated vocabulary standards such as ISO/IEC 22123-1 and ISO/IEC Guide 99:2007.
• Security and Privacy Control Updates: Revises references to NIST SP 800-53, now citing Revision 5 for enhanced security and privacy control guidelines within the SLA framework.

Applications

This amendment to the SLA metric model is essential for:

• Cloud Service Providers aiming to define and communicate clear, measurable SLA terms to customers, ensuring transparency and accountability.
• Enterprises and Organizations that rely on cloud services to establish contractual agreements with quantifiable performance criteria aligned with international standards.
• SLA Management Tools to implement the updated metric definitions, enabling automated monitoring and reporting of cloud service levels.
• Regulatory Compliance for industries where adherence to standardized service metrics is mandated or recommended.
• Interoperability and Benchmarking by providing a uniform metric model facilitating comparison and integration across various cloud environments.

Related Standards

• ISO/IEC 19086-1: Overview and SLA concepts forming the foundation of the SLA framework.
• ISO/IEC 19086-3: Core conformance requirements ensuring standardized SLA implementation.
• ISO/IEC 19086-4: Addresses security and protection of personally identifiable information (PII) within cloud SLAs.
• ISO/IEC 22123 series: Defines cloud computing vocabulary, concepts, and reference architecture critical for consistent SLA interpretation.
• ISO/IEC Guide 99:2007: Provides the international vocabulary of metrology applied in estimating and defining SLA metrics.
• NIST SP 800-53 Revision 5: Framework for security and privacy controls relevant to cloud SLA security components.

ISO/IEC 19086-2:2018/Amd 2:2025 represents a vital update supporting cloud computing's evolving landscape. It empowers stakeholders to specify, measure, and enforce SLAs with precision, thereby promoting trust, quality assurance, and effective cloud service governance worldwide.
