On this page, we need to make sure that Public Accessibility is set to Yes, set our Database Name, and scroll down to the Backup section. We are now on our last step: Configure Advanced Settings. Scroll down and enter your Instance Identifier, Username, and Password, then click next. This will limit our settings, but will be fine for our use case.

On this page, we can check Only enable options eligible for RDS Free Usage Tier. For our scenario, we can choose Dev/Test and click Next. Now, we should be on the Choose Use Case step. We should now be on a page similar to the one below, to select our database engine for our new instance. Once we are on the Instances page, let's click the Launch DB instance button in the top right corner. In the RDS dashboard, let's click Instances in the left navigation menu. The backups are performed during the daily maintenance window, which is defaulted to a random time based on the specified region. In Part 1, we'll focus on the simplest solution: backups.īy default, when you create an RDS instance in AWS, daily backups are enabled with a 7 day retention policy. A Multi-AZ setup consist of having multiple databases: a primary and one or more standbys that are in different availability zones. Multi-AZ stands for multiple availability zone, which is very telling of its nature. The master propagates changes over to the slave.

In its most basic form, you have a master and a slave. Outside of backups, this is the most commonly used configuration. This snapshot can then be used to recreate the database at that specific point in time. This simply refers to the action of taking a snapshot of a database in its current state. Let's take a moment to describe some of the available backup options within AWS. Today, we'll be taking a look at some of AWS's offerings for automatic backups, Multi-AZ, and read replicas. When it comes to databases, at one time or another, most of us have dealt with configuration of automated backups, replication, and the headaches that can come from those tasks. In particular, we will be focusing on a few techniques to deal with data loss mitigation and resiliency. In today's episode we are covering disaster recovery on AWS. If you're not so lucky, it can cost money, customer trust, bad publicity, and much more.

That can make for a bad week, if you're lucky. Now, imagine you lose your customer's data. Have you ever lost data? It can make for a bad day. Read part 2, which covers read replicas and multi-az.
