Cloud Computing Service Metrics Descriptions: Nist Sp 500-307
The National Institute of Standards and Technology (NIST) Special Publication 500-307 provides a comprehensive set of metrics for evaluating and comparing cloud computing services. These metrics cover various aspects of cloud services, including performance, reliability, security, and cost. Below are some key descriptions of the metrics outlined in NIST SP 500-307:
1. Performance Metrics:
– Response Time: Measures the time taken for a cloud service to respond to a user request.
– Throughput: Indicates the rate at which data can be transferred to and from the cloud service.
– Scalability: Evaluates the ability of the cloud service to handle increasing workloads without impacting performance.
2. Reliability Metrics:
– Availability: Reflects the percentage of time that a cloud service is operational and accessible to users.
– Fault Tolerance: Measures the ability of the cloud service to continue operating in the event of hardware or software failures.
– Redundancy: Assesses the presence of backup systems and data replication to ensure continuous availability.
3. Security Metrics:
– Data Encryption: Determines whether data transmitted to and stored in the cloud service is encrypted to protect against unauthorized access.
– Authentication: Evaluates the mechanisms used to verify the identity of users and ensure secure access to the cloud service.
– Compliance: Assesses the adherence of the cloud service provider to industry standards and regulations related to data security and privacy.
4. Cost Metrics:
– Subscription Fees: Represents the recurring charges associated with using the cloud service, such as monthly or annual subscription fees.
– Usage-Based Pricing: Refers to the charges based on the amount of resources consumed, such as storage, processing power, or network bandwidth.
– Total Cost of Ownership (TCO): Calculates the overall cost of using the cloud service, including initial setup costs, ongoing maintenance, and potential upgrades.
By considering these metrics outlined in NIST SP 500-307, organizations can effectively evaluate and select cloud computing services that best meet their performance, reliability, security, and cost requirements.
