You get to choose your database software, specifically MySQL, PostgreSQL, Oracle, SQL Server, or MariaDB. Here are the managed SQL database options:Īmazon RDS: Launched in 2009, this was the first of the managed databases on AWS. The most common names are Oracle and SQL Server (both proprietary and expensive), and MySQL, MariaDB, and PostgreSQL (all free and open source). Relational databases have been around for decades. Not sure about security groups? Start here. Lock down the IP address access by setting up the security groups. You can find more information here.Īnd one final tip for all the databases: Set up the security appropriately so that bots can’t randomly connect to your database and start trying to gain access. These are ways, for example, that MySQL stores its data. In terms of AWS, the read replicas are typically distributed across availability zones within a single region.įinally, when using MySQL-based databases, you need to understand the concept of database engines. Read requests (corresponding to select statements) can take place either in the main one or in any replicas called “read replicas”. With databases, you will typically have a main one through which write requests are sent, corresponding to your inserts and updates. Instead, the software runs on AWS’s own servers, and for the most part you’re only charged for the time the servers are running. At its most basic level, this means that you don’t have to provision your own EC2 servers you don’t have to create a Linux or Windows system that’s running continuously where your database software runs. You also need to understand the concept of “serverless” as it relates to AWS. When you provision servers within a single region, they can span multiple availability zones for easy replication. ![]() The idea is that if one data center goes down in another region, another will be there up and running. Within regions, there are multiple data centers each individual data center within a region is called an availability zone. AWS has data centers all over the planet, known as regions. Note that you need to understand the concept of availability zones on the platform. Where do you begin? Today let’s look at the different relational (SQL) types of databases available on AWS, along with the pros and cons of each. Amazon Web Services (AWS) offers several options for databases-so many, that choosing one can be overwhelming, even for developers skilled in all things AWS.
