One of the biggest fears developers have when moving to the cloud is a surprise bill. But did you know that Amazon DynamoDB has a "Forever Free" tier? Unlike many AWS services that expire after 12 months, DynamoDB gives you a generous amount of resources every single month at zero cost. Here’s how you can take advantage of it.
1. What's Included in the Free Tier?
AWS provides 25 GB of storage for free every month. That is enough to store millions of small data records! Additionally, you get 25 provisioned Write Capacity Units (WCU) and 25 provisioned Read Capacity Units (RCU). For a small to medium application, this is more than enough to handle your traffic without ever seeing a charge.
2. Choose the Right Capacity Mode
To stay within the free tier, you should generally use Provisioned Capacity and set your RCU and WCU to 25 or less. While "On-Demand" mode is convenient, its free tier limits are calculated differently and might lead to small charges if you have high bursts of traffic. Stick to provisioned limits to ensure a $0 bill.
3. Optimize Your Data Usage
To make that 25 GB last as long as possible, be smart about what you store. Don't store large images or files directly in DynamoDB—use Amazon S3 for that and just store the link in your database. Keep your attribute names short and avoid duplicating data unnecessarily.
4. Set Up Billing Alerts
Even though the free tier is great, it’s always a professional best practice to set up AWS Budgets. You can create an alert that sends you an email if your usage ever exceeds $0.01. This gives you peace of mind while you focus on building your amazing application!
💡 Key Takeaway: The DynamoDB free tier is the perfect sandbox for developers. You can learn, build, and even launch a small startup without paying a single rupee for your database!
