AWS Database Specialty Syllabus:
Section | Objectives |
---|---|
Workload-Specific Database Design - 26% |
|
Select appropriate database services for specific types of data and workloads. |
- Differentiate between ACID and BASE workloads. - Explain appropriate uses of types of databases (for example, relational, key-value, document, in-memory, graph, time series, ledger). - Identify use cases for persisted data compared with ephemeral data. |
Determine strategies for disaster recovery and high availability. |
- Select Region and Availability Zone placement to optimize database performance. - Determine implications of Regions and Availability Zones on disaster recovery and high availability strategies. - Differentiate use cases for read replicas and Multi-AZ deployments. |
Design database solutions for performance, compliance, and scalability. |
- Recommend serverless compared with instance-based database architecture. - Evaluate requirements for scaling read replicas. - Define database caching solutions. - Evaluate the implications of partitioning, sharding, and indexing. - Determine appropriate instance types and storage options. - Determine auto scaling capabilities for relational and NoSQL databases. - Determine the implications of Amazon DynamoDB adaptive capacity. - Determine data locality based on compliance requirements. |
Compare the costs of database solutions. |
- Determine cost implications of DynamoDB capacity units, including on-demand capacity compared with provisioned capacity. - Determine costs associated with instance types and automatic scaling. - Design for costs, including high availability, backups, multi-Region, Multi-AZ, and storage type options. - Compare data access costs. |
Deployment and Migration - 20% |
|
Automate database solution deployments. |
- Evaluate application requirements to determine components to deploy. - Choose appropriate deployment tools and services (for example, AWS CloudFormation, AWS CLI). |
Determine data preparation and migration strategies. |
- Determine the data migration method (for example, snapshots, replication, restore). - Evaluate database migration tools and services (for example, AWS Database Migration Service [AWS DMS], native database tools). - Prepare data sources and targets. - Determine schema conversion methods (for example, AWS Schema Conversion Tool [AWS SCT]). - Determine heterogeneous compared with homogeneous migration strategies. |
Perform and validate data migration. |
- Design and script data migration. - Run data extraction and migration scripts.. - Verify the successful load of data. |
Management and Operations - 18% |
|
Determine maintenance tasks and processes. |
- Account for the AWS shared responsibility model for database services. - Determine appropriate maintenance window strategies. - Differentiate between major and minor engine upgrades. |
Determine backup and restore strategies. |
- Identify the need for automatic and manual backups and snapshots. - Differentiate backup and restore strategies (for example, full backup, point-in-time, encrypting backups cross-Region). - Define retention policies. - Correlate the backup and restore to recovery point objective (RPO) and recovery time objective (RTO) requirements. |
Manage the operational environment of a database solution. |
- Orchestrate the refresh of lower environments. - Implement configuration changes (for example, in Amazon RDS option groups and parameter groups, or DynamoDB indexing changes). - Automate operational tasks. - Take action based on AWS Trusted Advisor reports. |
Monitoring and Troubleshooting - 18% |
|
Determine monitoring and alerting strategies. |
- Evaluate monitoring tools (for example, Amazon CloudWatch, Amazon RDS Performance Insights, database native). - Determine appropriate parameters and thresholds for alert conditions. - Use tools to notify users when thresholds are breached (for example, Amazon Simple Notification Service [Amazon SNS], Amazon Simple Queue Service [Amazon SQS], CloudWatch dashboards). |
Troubleshoot and resolve common database issues. |
- Identify, evaluate, and respond to categories of failures (for example, troubleshoot connectivity; instance, storage, and partitioning issues). - Automate responses when possible. |
Optimize database performance. |
- Troubleshoot database performance issues. - Identify appropriate AWS tools and services for database optimization. - Evaluate the configuration, schema design, queries, and infrastructure to improve performance. |
Database Security - 18% |
|
Encrypt data at rest and in transit. |
- Encrypt data in relational and NoSQL databases. - Apply SSL connectivity to databases. - Implement key management (for example, AWS Key Management Service [AWS KMS], AWS CloudHSM). |
