Understanding these terms and knowing the best practices associated with each is crucial for effectively managing databases with NDB.
Do's and Don'ts for Important NDB Terms and Concepts
Term/Concept | Do Not Do This (Incorrect Approach) | Do This Instead (Correct Approach) |
---|---|---|
Copy Data Management (CDM) | "Ignore copy management policies, assuming that any copy made is automatically secure and optimized." | "Always define copy data management policies to manage, optimize, and secure database copies to minimize storage usage and ensure data protection." |
Time Machine | "Use a generic Time Machine configuration for all databases, ignoring different retention, backup, and recovery needs." | "Create custom Time Machine SLAs for different databases, tailored to their specific backup, retention, and recovery requirements." |
Provisioning Profiles | "Apply a single provisioning profile to all types of databases, regardless of their specific needs." | "Create specific provisioning profiles for each database type (e.g., SQL, NoSQL) to match performance, security, and capacity requirements." |
Data Access Management (DAM) | "Provide unrestricted data access to all users, assuming that broad access simplifies management." | "Implement fine-grained Data Access Management (DAM) policies to control and monitor who has access to what data, ensuring security and compliance." |
Define Custom SLAs for Time Machine | "Rely on the default SLAs for all Time Machine configurations, assuming they will cover every scenario." | "Define custom SLAs for Time Machine to align with the business's recovery point objectives (RPO) and recovery time objectives (RTO)." |
Use of Clones and Snapshots | "Overuse clones and snapshots without understanding their impact on storage and performance." | "Use clones and snapshots judiciously, monitoring their impact on storage and ensuring they are aligned with organizational data management strategies." |
Monitor Data Usage and Efficiency | "Assume data efficiency and usage are automatically optimized without regular monitoring." | "Regularly monitor data usage and efficiency metrics to identify opportunities for optimization and to ensure the effective use of storage resources." |
Maintain Secure Data Access | "Grant all users access to sensitive data, assuming there are no compliance concerns." | "Maintain secure data access by applying the principle of least privilege and regularly reviewing and adjusting permissions to match user roles and responsibilities." |
Implement Backup and Retention Policies | "Implement a 'one-size-fits-all' approach for backup and retention policies, ignoring the unique needs of different databases and applications." | "Customize backup and retention policies for each database based on its importance, usage patterns, and regulatory requirements." |
Regularly Review and Update Policies | "Set policies once and assume they will always be adequate, without reviewing or updating them regularly." | "Regularly review and update policies to ensure they remain effective, relevant, and aligned with current business needs and regulatory requirements." |
Understand Resource Requirements | "Ignore the specific resource requirements of different databases, leading to under or over-provisioning." | "Understand and plan for the specific resource requirements of each database type, including compute, memory, and storage, to ensure optimal performance." |
Monitor Performance and Alerts | "Ignore performance metrics and alerts, assuming no news is good news." | "Regularly monitor performance metrics and set up alerts to detect issues early and optimize database performance." |
