The previous post was on Events as a measurement of Cloud Database performance with a focus on the pricing of the cloud database. We factored in the advantages of a public cloud managed RDS over a self-managed AWS instance namely: upgrades, backup and failover are provided as a services, there is more infrastructure and db Security, the database appears as a managed appliance and the failover is a packaged service.
The managed database instance types offer a range of CPU and memory selections. Moreover their storage is scaleable on demand. Automated backups have a retention period of 35 days and manual snapshots are stored in S3 for durability. An availability zone is a physically distinct independent infrastructure. Multiple availability zones each of which is a physically distinct independent infrastructure comes with database synchronization so they are better prepared for failures. Read replicas help offload read traffic. Entire database may be snapshot and copied across region for greater durability. Compute, Storage and IOPS are provisioned constitute the bill.
Performance is improved with offloading read traffic to replicas, putting a cache in front of the RDS and scaling up the storage or resizing the instances. CloudWatch alerts and DB Event notifications enabled databases to be monitored.
In short, RDS allows developers to focus on app optimization with schema design, query construction, query optimization while allowing all infrastructure and maintenance to be wrapped under managed services.
RDS alone may not scale in a distributed manner. Therefore software such as ScaleBase allows creation of a distributed relational database where database instances are scaled out. Single instance database can now be transformed into multiple-instance distributed relational database. The benefits from such distributed database include massive scale, instant deployment, keeping all RDS benefits from single-instance, automatic load balancing especially with lags from replicas and splitting of reads and writes, and finally increased ROI with no app code requirements.
