Cloud-native database management
The Amazon Relational Database Service (RDS) enables developers to create and manage relational databases in the cloud. As part of Amazon Web Services, this service can integrate with Amazon’s NoSQL database tool, SimpleDB, supporting applications that have relational and non-relational database needs. It also works with MySQL, Oracle, and Microsoft SQL for applications that already leverage these database tools.
Amazon RDS was first released in October 2009, with support for MySQL databases. Subsequent releases have added support for additional database types, with PostgreSQL and MariaDB being the most recent.
RDS Features and Benefits
RDS is designed to reduce operational costs and overcome some common challenges that businesses experience when running databases through tools like MySQL. Its primary benefits include:
- Precise, independent scaling: A hardware-based solution can cause inefficiencies in database management because resources (CPU, memory, storage, etc.) come bundled together. RDS allows developers to easily change these factors independently so they can fit them to the needs of their databases.
- Ease of implementation: Because RDS integrates with common database applications, developers can continue working in the programs with which they are already familiar.
- Process automation: Database backups, software patching, failure detection, and recovery are all a part of ongoing database management that can lead to significant costs. Amazon RDS automates these to reduce the administrative burdens.
- Security: Amazon RDS restricts access to database instances, where advanced privileges are required, and prevents shell access. Its integration with AWS makes it possible to manage databases in the Virtual Private Cloud (VPC) and expand security features with AWS Identity and Access Management (IAM).
- Reliability and availability: Amazon RDS includes replication that allows for high availability on high-priority databases and automatic failover if a primary database becomes unavailable.
- Cost: Amazon’s pricing options for RDS include on-demand and hourly rates, adapted to the actual resource demands of database applications
Faster deployment: RDS overcomes the need for provisioning and investment in hardware resources, speeding up the time from conception to deployment.
Monitoring and Tracking Database Instances With RDS
When running database applications through Amazon RDS, developers and administrators will need to monitor performance. AWS provides the free CloudWatch service for basic monitoring, and some basic charts are available through the Amazon RDS console. Administrators also can subscribe to event notifications so they can be alerted when a database change occurs.
In most cases, administrative, development, and security teams will need to set up more improved visibility through log management. This can be handled seamlessly through an HTTP collector with some minimal configuration at the outset.
