Day 2 - Amazon RDS - Letting AWS run your Low Admin, High Performance Database
- 1. RDS - Letting AWS run your Low Admin, High Performance Database Ganesh Raja, Solutions Architect Amazon Internet Services Private Ltd.
- 2. AWS Database Services v Amazon RDS DynamoDB Amazon Redshift ElastiCache
- 3. Why do we offer 4 database services…?
- 5. v
- 6. How Do We Decide What to Build? v • Start with the customer and work backwards • Enable new things that customers couldn’t do before… • Make things customers could already do much cheaper, simpler and better
- 7. Relational Databases MySQL, Aurora, PostgreSQL, Oracle, SQL Server Fully managed; zero admin Amazon RDS Aurora
- 8. Why Did We Create Amazon RDS? v • All existing apps use relational databases • Many new apps will need relational databases • But you can already run databases on Amazon EC2…
- 9. Key Insight: Relational Databases are Complex v • Our experience running Amazon.com taught us that relational databases can be a pain to manage and operate with high availability • Poorly managed relational databases are a leading cause of lost sleep and downtime in the IT world!
- 10. Why choose Amazon RDS? v Schema design Query construction Query optimization Migration Backup and recovery Patching Configuration Software upgrades Storage upgrades Server upgrades Hardware issues Focus your team here Let AWS focus here
- 11. We Made Things Cheaper, Easier and Better v • Push button provisioning. Automated scaling, patching, security, backups, restores and general care and feeding • Lower TCO because we manage the muck • Get more leverage from your teams • Focus on the things that differentiate you • Built-in High Availability and Cross Region replication across multiple data centers • Now even a small startup can leverage multiple data centers to design highly available apps with over 99.95% availability
- 12. RDS Database instances: scalable CPU, memory, storage v • Database instance types offer a range of CPU and memory selections • Scale up or down among instance types on demand • Database storage is scalable on demand • Choose standard storage for lower cost at low IOPS • Choose Provisioned IOPS for high, predictable performance and online scaling
- 13. How RDS backups work v • Automated backups • Restore your database to a point in time • Enabled by default • Choose a retention period, up to 35 days • Manual snapshots • Initiated by you • Persist until you delete them • Stored in Amazon Simple Storage Service (Amazon S3) • Build a new database instance from a snapshot when needed
- 14. High Availability Multi-AZ Deployments Enterprise-grade fault tolerance solution for production databases v
- 15. Choose Multi-AZ for greater availability, durability v • An availability zone is a physically distinct, independent infrastructure • With Multi-AZ operation, your database is synchronously replicated to another AZ in the same AWS Region • Failover occurs automatically in response to the most important failure scenarios • Planned maintenance is applied first to backup
- 16. Customers Love Multi-AZ Multi-AZ Instances as a share of all RDS Instances v 26% 40% 45% 40% 35% 30% 25% Oct-12 Jan-13 Apr-13 Jul-13 Oct-13 Jan-14 Apr-14 Jul-14 Oct-14
- 17. Choose Read Replicas for greater scalability v • Help your app scale by offloading read traffic to an automatically maintained read replica • Create multiple read replicas, load-share traffic • Easy to set up
- 18. Choose cross-region snapshot copy for even greater durability, ease of migration v • Copy a database snapshot to a different AWS Region • Warm standby for disaster recovery • Or use it as a base for migration to a different region
- 19. Choose cross-region read replicas for enhanced data locality, even more ease of migration v • Even faster recovery in the event of disaster • Bring data close to your customers • Promote to a master for easy migration
- 20. How RDS billing works Monthly bill = + GB + db.m3.xlarge; MySQL; Oregon; Single-AZ; On-Demand 100 GB Provisioned IOPS = 720 hrs * $0.60 + 100 GB * $0.125 + 1,000 IOPS * $0.10 = $544.50 Assumes DB instance accessed only from EC2 Further details at http://aws.amazon.com/rds/pricing/ Provisioned 1,000 IOPS
- 21. Save money with RDS Reserved Instances v • Pay a low up-front fee to get a lower hourly price on database instances for a 1- or 3-year term • The lower-price entitlement applies to any running instance matching its description • Choose among Heavy, Medium, Light RIs Month 1 Month 2 Month 3 Month 4 Month 5 Month 6 Month 7 Month 8 Month 9 Month 10 Month 11 Month 12 On-demand 544.50 1,089.00 1,633.50 2,178.00 2,722.50 3,267.00 3,811.50 4,356.00 4,900.50 5,445.00 5,989.50 6,534.00 Heavy RI 1-yr 1,508.10 1,750.20 1,992.30 2,234.40 2,476.50 2,718.60 2,960.70 3,202.80 3,444.90 3,687.00 3,929.10 4,171.20 Start saving here
- 22. How to scale with Amazon RDS v • Scale up or down with resizable instance types • CPU to 32 vCPUs, RAM to 244 GiB • Scale your storage up with a few clicks • Scale while online • Easy conversion from standard to Provisioned IOPS storage • Offload read traffic to Read Replicas • Put a cache in front of Amazon RDS • Amazon ElastiCache for Memcached or Redis • Or your favorite cache, self-managed in Amazon EC2 • Amazon RDS takes some of the pain out of sharding
- 23. Best practices for Amazon RDS v • Strongly consider Provisioned IOPS storage • Strongly consider Multi-AZ deployments • Make maximum use of ability to rapidly provision test environments • Create regular DB Snapshots • Test recovery from them • Configure CloudWatch alerts and DB Event notifications
- 24. How to migrate data into RDS v • Basic technique: dump and restore • Simple, but requires downtime RDS for MySQL RDS for Oracle RDS for SQL Server RDS for PostgreSQL mysqldump Data Pump Generate/ Publish scripts pgdump mysqlimport SQL Loader Bulk Copy (bcp) copy
- 25. How to migrate data into RDS, continued • Advanced technique: apply the deltas v • Replay transactions against the migration target RDS for MySQL RDS for Oracle RDS for SQL Server RDS for PostgreSQL mysqlbinlog Mview replication Linked servers Use row metadata to capture modified rows Tungsten Replicator Golden Gate, Dbvisit, Attunity, Dell SharePlex SSIS

Editor's Notes
- We have designed specific Database solutions for specific use cases based on what customers tell us For us, everything starts with the customer and we work backward from the customer to design a product Designed to enable new things that customers could not do before And To make things customers could do before, much cheaper, much easier, much better
- You can only scale up with storage.
- Because Multi-AZ minimizes the downtime impact of scheduled maintenance, it gives value even to deployments in which the app servers are in a single AZ. But it’s still best to have the instances spread across multiple AZs.
- Read replicas are available for Amazon RDS for MySQL. Not only can read replicas offload read traffic, they can also be a standby failover. Manually promote a read replica to master status. If you go this route, be sure to put the RR in a different AZ, and choose a different maintenance window.
- Cross region snapshot copy is available for all RDS engines. However, you can’t use it to copy snapshots from an RDS/Oracle instance that is using Transparent Data Encryption.
- Cross-region read replicas are available for Amazon RDS for MySQL.
- db.m3.xlarge instance: 4 vCPUs, 15 GiB RAM db.m3.large instance: 2 vCPUs, 7.5 GiB RAM
- The break-even period for a Heavy RI is well in advance of the expiration of the 1- or 3-year term. Reserved instances are keyed to DB instance class, DB engine, and the choice of Single-AZ vs. Multi-AZ. Heavy RIs are appropriate for production database workloads. Use Light or Medium RIs for test/dev databases run only a few hours per day
- Provisioned IOPS storage delivers predictable performance. In Multi-AZ deployment, scheduled maintenance happens first on the standby. Build and discard test environments. CloudWatch is good for watching load thresholds. If you are using Cross Region Read Replicas, use CloudWatch to monitor replica lag.
