A NoSQL data model can store JSON documents or key value pairs and is typically hosted in a distributed computing environment for fault tolerance and redundancy. NoSQL databases are very different from traditional RDBMS in that they have a flexible data model where a “row” of data may not have the same number of attributes as the next row. Back-end relational database for any enterprise applicationĭynamoDB is Amazon’s footprint in the NoSQL world.Achieving these types of scalability in a traditional data center would be time and cost intensive, if not prohibitive. The underlying storage can be made to perform for a specified number of Input/Output (I/O) per second with provisioned IOPs.
If an instance needs more power, it can be upgraded to a higher-end server without any hassle at all. An RDS instance can be as small as having 1 vCPU and 2 GB RAM or as large as having 64 vCPUs and 488 GB RAM. Perhaps the best feature of RDS is its ability to scale. The retention can go back to the last 35 days. With RDS automated backups, it’s also possible to restore an instance within five minutes of any point in time in the backup retention period. Customers can either bring their own licenses for the database software, or purchase the license as part of the instance cost. Behind the scenes, AWS takes care of all the installation, patching, maintenance, security, failover (for multi-AZ instances), snapshots, etc. Since this is a managed solution, users can’t directly access the underlying host for the simple fact that there is no remote desktop or SSH access at the operating system level. Once the options are chosen, RDS provisions a database instance, changes any configuration settings and makes the instance available for the user. The network (VPC) and region where the instance should run.Any non-default configuration parameter settings.Backup schedules and maintenance preferences.

What database software they would like to install.What this means is that users make a few fundamental choices, including the following: RDS allows users to spin up any of these database instances with minimal input from the user. With RDS, AWS customers don’t need to install, configure and manage popular relational database systems like Oracle, Microsoft SQL Server, PostgreSQL, MariaDB or MySQL. AWS Relational Database Service (RDS) is Amazon’s cloud-hosted, managed RDBMS solution.
