![]() But although this sounds impressive, Aurora Serverless is not the most robust solution, being more subject that most of the other solutions on this list to restrictions. Aurora Serverless, however, will automatically start-up, scale-up, scale down and shut down in-line with your application’s needs. And the user may choose to run DynamoDB on on-demand or in provisioned capacity mode, in which a limit can be set on scale, much like RDS.Īurora – How Aurora scales depends on whether it’s running on RDS or Aurora Serverless. At the extreme end of things, however, Redshift is probably the better choice, since its Concurrency Scaling feature – which costs extra – allows it to take on a virtually limitless amount of queries.ĭynamoDB – DynamoDB scales seamlessly with no impact on performance. Using Elastic Resize, Redshift can be scaled more quickly, but it still doesn’t quite close the gap with RDS. Redshift – Redshift’s infrastructure is more complicated, meaning there’ll be more downtime and complexity involved in scaling. It can be run using a reserved capacity or on-demand. RDS – Because RDS is less complex, it’s easier to scale – requiring just a few clicks on the AWS Console to determine an auto-scale max capacity. ![]() Aurora is MySQL and PostgreSQL compatible which means that the language which programmes it is functionally similar to these engines, although it is an engine in its own right.įurther, Aurora has significantly higher performance stats compared to MySQL and PostgreSQL run on RDS.Īurora is also an enterprise solution, even when used with RDS. Amazon AuroraĪmazon Aurora is a database engine that can be run on RDS or as Aurora Severless. Key-value databases are best suited to certain use cases such as session data and shopping cart information and can achieve a fast throughput of read/write requests.ĭynamoDB is also an enterprise-level solution. This makes the data stored in DynamoDB ‘dynamic’ which means it’s easier to modify. DynamoDBĭynamoDB is a key-value database which runs the NoSQL engine, this means it treats all data within it as being composed of a list of attributes and values as opposed to data points constituted by the relationships between cells and column/row headers (as in a relational database). Redshift is an enterprise-level DB, mostly used by large companies. Because of its vast storage potential and differing functionality, Redshift is sometimes referred to as a data warehouse. This means it’s especially suited to processing analytical queries involving more complex calculations. Redshift is an OLAP database, standing for ‘online analytical processing’. It can be more costly, more complex to work with and much more powerful. Amazon Redshif tĪmazon Redshift is also a managed database service and a relational database, running its own engine adapted from PostgreSQL. This is a little simplified, as a relational database is a bit more complex than an Excel workbook, but not much!. Like all the other databases on this list, excluding DynamoDB, RDS is a relational database which simply refers to the nature of the data storage.Īs in an Excel workbook which has been formatted as a table, the data is constituted by its value – the data in the cell – and the relationship that cell has to its column/row headers. ![]() It’s worth noting here that RDS is the only DB on this list compatible with the popular Microsoft SQL Server, although those wishing to access the benefits of the other services might consider migrating to an engine compatible with Redshift, DynamoDB or Aurora. It’s compatible with six popular database engines – Amazon Aurora, MySQL, MariaDB, PostgreSQL, Oracle and Microsoft SQL Server, which means it can be operated just like any of these databases. The one for when you’re simply looking to offload your database management workload. What database solutions are offered by AWS? Amazon RDSĪmazon RDS is the first-port-of-call service. ![]() So, here’s an overview of each one to help inform your decision. However, each service is very different, and it can be difficult to determine which best fits your need (if you’re going it alone instead of choosing an AWS managed hosting provider). ![]() In recent years, more and more providers have been offering managed, cloud-based database services, meaning they handle infrastructure needs, software patching, back-ups and many other administrative tasks.ĪWS offers a range of database solutions, with the four most popular being Amazon Aurora, Redshift, RDS and DynamoDB. Managing a database can be time-consuming, but often there’s no need to. ![]()
