The AWS Database Services, Mapped

“Cloud database hosting on AWS” is really a menu, and knowing what’s on it is half the decision. Amazon RDS runs managed relational databases (MySQL, PostgreSQL, MariaDB, SQL Server, Oracle); Aurora is AWS’s own high-performance MySQL/PostgreSQL-compatible engine. DynamoDB is serverless key-value/document storage at any scale. ElastiCache provides in-memory Redis/Memcached speed. Redshift is the analytics warehouse, and specialty engines like DocumentDB and Neptune cover document and graph workloads.

How to Choose: Start From the Workload

Match the service to the job, not the marketing. Transactional app data — orders, users, inventory — belongs in RDS or Aurora; if that’s your case, our guide to Amazon RDS for database hosting goes deeper. Massive-scale lookups and flexible records suit DynamoDB. Speed-critical caching goes to ElastiCache. Reporting across millions of rows is Redshift territory.

Most real applications combine two: a relational core plus a cache is the classic, boring, correct stack.

Managed Service or Self-Managed on EC2?

You can also install any database on a plain EC2 server. That buys full control — exact versions, custom extensions, OS-level tuning — and costs you all the operational work: patching, backups, replication, failover. The managed route wins for most teams, for the same reasons any database-as-a-service platform does: the undifferentiated maintenance disappears. Choose EC2 self-managed only when you need something RDS genuinely can’t do.

What AWS Database Hosting Costs

Four meters run at once: compute (instance hours, or serverless capacity units), storage (GB-month plus provisioned IOPS if you need them), backups beyond the free retention window, and data transfer out. Instance-based pricing is predictable; serverless options (Aurora Serverless, DynamoDB on-demand) track usage — better for spiky loads, pricier for steady heavy ones. Reserved instances or Savings Plans cut steady-state costs substantially.

Production Basics: Availability and Migration

For anything customer-facing, turn on Multi-AZ so a standby in a second zone takes over on failure — the trade-offs are covered in our guide to high-availability database solutions. And if you’re moving an existing database in, AWS DMS with continuous replication keeps cutover downtime to minutes; the full playbook is in our database migration guide.

Common AWS Database Mistakes

The recurring ones: leaving a database publicly accessible instead of in a private subnet, running production on a single AZ to save a few dollars, oversizing the instance “to be safe” and paying for idle capacity, ignoring the backup retention window until the day a restore is needed, and self-managing on EC2 without anyone owning the DBA work.

Aurora vs Standard RDS: When the Upgrade Is Worth It

Both run managed MySQL and PostgreSQL, so the choice confuses everyone at first. Standard RDS runs the stock engine on an instance you size — simple, predictable, and the right default for steady small-to-medium workloads. Aurora is AWS’s re-engineered, compatible version: storage grows automatically, replicas stay closer to current, and failover is faster — at a higher per-instance price.

Aurora earns its premium in three situations: the application is availability-sensitive enough that faster failover matters, read traffic needs several low-lag replicas, or the load is genuinely spiky — where Aurora Serverless v2 scales database capacity up and down automatically instead of forcing you to size for the peak. If none of those describe you, standard RDS does the job for less.

Read Replicas vs Multi-AZ: Different Jobs, Often Confused

These two features both “add another copy” and solve completely different problems. Multi-AZ is for availability: a synchronized standby in a second data center takes over automatically if the primary fails. You don’t query it — it exists for the bad day. Read replicas are for scale: asynchronous copies that serve read traffic — dashboards, reports, product pages — taking load off the primary, at the cost of replicas trailing slightly behind.

The practical pattern for a revenue-bearing application is both: Multi-AZ on the primary for failover, plus a replica when read-heavy features start dragging. Neither is a backup — a bad UPDATE replicates everywhere within seconds.

Backups and Point-in-Time Recovery on RDS

RDS automated backups combine daily snapshots with continuous transaction-log archiving, which buys you point-in-time recovery: restore to any moment within the retention window, such as one minute before the accidental table wipe. Retention is configurable up to 35 days; manual snapshots persist beyond that for long-term keeps, and copying snapshots to a second region is cheap disaster insurance.

One detail bites people: restores create a new database instance rather than rewinding the existing one, so your recovery drill should include repointing the application. Run that drill once before you need it — the restore that has never been rehearsed always takes longest at the worst time.

Tuning: The First Three Things to Check

When an AWS-hosted database feels slow, three checks resolve most cases before any resizing. First, open Performance Insights and look at the top queries by load — one unindexed query usually dominates, and an EXPLAIN confirms the missing index. Second, check connections: serverless and heavily-scaled applications can exhaust the connection limit, which looks like random failures; RDS Proxy pools connections and fixes the pattern. Third, review the parameter group — engine settings like memory buffers ship with generic defaults that modest tuning can improve. Only after those three does “buy a bigger instance” deserve consideration.

Locking Down an AWS Database

The security checklist for AWS databases is short and non-negotiable: the instance lives in a private subnet with security groups admitting only the application servers; encryption at rest (KMS) is enabled at creation — it can’t be bolted on later without a migration; TLS protects every connection; credentials live in Secrets Manager with automatic rotation rather than in config files; and for supported engines, IAM database authentication lets applications connect with short-lived tokens instead of long-lived passwords. Each item is a checkbox at setup time and a project to retrofit — do them on day one.

A Worked Sizing Path

Databases are best sized by evidence, not anxiety. Start on the smallest burstable instance class with modest storage — for a new application it’s almost always enough, and it may ride the free tier for its first year. Turn on Multi-AZ the day the application starts earning money. Add a read replica when Performance Insights shows read queries crowding the primary. Move up an instance size when you see sustained CPU pressure or memory-driven disk churn — real symptoms, not projections. Every step is reversible and driven by a measurement, which is precisely the advantage managed cloud databases have over the buy-a-big-server-up-front era.

A Pre-Launch Database Checklist

Before an AWS-hosted database carries production traffic, walk this list once — each item is minutes now and hours of grief later.

Network: the instance sits in a private subnet, and its security group admits only the application servers — verify by trying to connect from outside and failing.

Encryption: at-rest encryption was enabled at creation (it can’t be added in place later) and the application connects over TLS.

Availability: a deliberate Multi-AZ decision is on record — on for revenue-bearing systems, consciously deferred for the rest, never simply forgotten.

Backups: retention is set to a period that survives a slowly-discovered mistake, a manual snapshot exists from before launch, and someone has actually performed a test restore and repointed a client at it.

Credentials: the app reads its database secret from Secrets Manager, rotation is scheduled, and no password appears in code or config files.

Visibility: alarms exist for CPU, storage headroom, and connection count, and Performance Insights is on so the first slow week can be diagnosed instead of guessed at.

Teams that can tick all six boxes rarely have database emergencies — they have maintenance windows.

Frequently Asked Questions

Should I choose Aurora or standard RDS?

Standard RDS is the right default for steady small-to-medium workloads — simpler and cheaper. Aurora earns its premium when failover speed matters, you need several low-lag read replicas, or spiky load fits Aurora Serverless v2’s auto-scaling capacity.

What is the difference between Multi-AZ and a read replica?

Multi-AZ is availability: a synchronized standby that takes over on failure but serves no traffic. Read replicas are scale: async copies that serve read queries but trail slightly behind. Production apps often want both — and neither is a backup.

How long does RDS keep backups?

Automated backups with point-in-time recovery are configurable up to 35 days. Manual snapshots persist until you delete them, and copying snapshots to another region is inexpensive disaster insurance. Remember restores create a new instance — rehearse repointing your application.
