This section of the Solution Architect Associate learning path introduces you to the AWS database services relevant to the SAA-C02 exam. We then understand the service options available and learn how to select and apply AWS database services to meet specific design scenarios relevant to the Solution Architect Associate exam.

- Understand the various database services that can be used when building cloud solutions on AWS
- Learn how to build databases using Amazon RDS, DynamoDB, and Redshift
- Learn how to create Elasticache and Neptune clusters
- Understand AWS database costs
Now that we have looked at primary storage and I/O costs for your database, let’s now take a look at what costs you will incur for backups that you take of your database. Firstly, I want to identify which actions and considerations need to be taken into account and that will affect how your backup storage fluctuates:
- The first point I want to make, and it might surprise you, is that Amazon RDS does not charge any backup storage costs that equates to the total sum of provisioned storage used with your databases within a specific region. So for example, Assume you had a MySQL DB with provisioned storage of 150GiB-Month DB, plus a MariaDB DB with 450GiB in a single region. Amazon RDS would not charge you for any storage utilised up to 600GiB-Month.
- Any backup storage used over this ‘free’ tier is charged at $0.10 per GiB-Month, regardless of the region for:
- SQL Server
- Any backup storage used over this ‘free’ tier for Aurora is charged differently based upon the region. Currently at the time of writing this course, it is $0.022 per GiB-Month in the London region
- Any automated backups taken use backup storage
- Any manual snapshots that are taken of your database will also use backup storage
- By extending your backup retention periods (how long you’d like to keep your backups for) will increase the amount of storage required for backups
- Backup storage is calculated based upon the total amount of backup storage consumed within a specific region across all your RDS databases
- If you copy your backups to another region, this will also increase the amount of backup storage used within that new region
So all in all, backup storage for your RDS databases is relatively simple to calculate and inexpensive bearing in mind it is free to backup 100% of your provisioned database storage.
Let me now move onto Backtrack storage costs with Amazon Aurora.
