A web-based console provides comprehensive monitoring information, making your operations easy and visual.

You can flexibly scale resources based on your service requirements and pay for only what you use. Did you find this page helpful? Submit successfully! Failed to submit the feedback. A DB instance is a particular database 'environment' set up by the user. It can include more than one database, and when users apply settings to one instance they can automatically apply them across all the included databases.

A manager can configure these instances for a specific CPU and storage usage. Users can also set up 'read replicas. You can use read replicas to offload read-only traffic from the principal or 'master' DB instance. If you set up Multi-AZ availability zone , you may also set up read replicas in a different AZ from the principal database, meaning a different physical location. This can improve performance for certain locations.

Finally, you can promote a read replica to the primary instance, typically with less than 30 seconds of delay, if the master DB experiences failover. This avoids problematic downtime.

When hosting data in the cloud, it is crucial that you can access it at the time or place of your choosing. Amazon RDS can provide high availability via a feature called Multi-AZ deployment, which maintains a redundant copy of your data in a separate location.

The Multi-AZ service-level agreement guarantees a database uptime of at least Failovers can be processed with minimum latency through synchronous replication to a secondary database. Trying to scale an on-premise self-hosted database can be a serious challenge, but Amazon RDS makes it much simpler.

Amazon RDS offers two different types of automatic scaling: horizontal adding more machines and vertical adding more resources. The service comes equipped with a load balancer that can distribute requests evenly when the database is under increased demand. Amazon RDS is unique compared to many other similar services in that the CPU and storage can scale independent of one another in a particular database instance.

You can also easily scale them back down. If, for example, you have a major sale or event in your business that only lasts a month, you will want to have the ability to quickly scale down again afterward. Users can also add RDS instances to an instance class so that they can scale them simultaneously. Also, Amazon Aurora has an auto-scaling configuration to scale compute capacity as needed called Amazon Aurora Serverless.

This is just one of the many ways AWS offers an edge over the competition when it comes to scalability. Different types within the RDS engine may offer slightly different levels or kinds of security, but some things you can generally count on are automated patching and security monitoring.

Amazon RDS includes a Performance Insights dashboard that makes it easier for users to analyze and troubleshoot the performance of their relational databases. Amazon CloudWatch allows users to better monitor performance and form metrics so you can get a clearer view of your business.

Pricing in Amazon RDS is very straightforward. With no up-front costs to worry about, users can pay for exactly what they need every month.

It comes without any minimum fee. You only have to pay full price for active instances. You can reserve instances for long periods of time and receive a discount. Additionally, you can pause database instances for a full week if necessary.

Amazon RDS includes multiple service tiers with different levels of storage and performance that can fit the needs of most users. The free tier offers hours of use with 20 GB of storage for anyone who wants to test out the service. Feature-level pricing can be complex and depends on which database engine you are using. Thankfully, Amazon offers a pricing calculator. While Amazon RDS can be a strong offering for users who want a managed relational database in the cloud, it is not the only alternative out there.

However, with so many different options for building a relational database, these solutions do not always come with a built-in way to integrate data from multiple sources, which is essential in order to gain deeper insights for your business needs. The good news is you can easily integrate Amazon RDS with other data sources by using a third-party solution such as Xplenty.
