PostgreSQL cloning and branching. Database Lab Engine (DLE) provides blazing-fast database cloning and branching to build powerful development, test, QA, and staging environments. Instantly create full-size clones of your production database and use them to test your database migrations, optimize SQL, or deploy full-size staging apps.
The AWS Marketplace version of DLE comes with simplified installation and configuration, an embedded monitoring system (Netdata), and a subscription to support (Standard Edition).Typical pilot setup costs less than a cup of coffee!Timeline:

Create and configure DLE instance - ~10 minutes
Wait for the initial data provisioning (full refresh) - ~30 minutes (for a 100 GiB database; DLE is running on a very small EC2 instance, r5.xlarge)
Try out cloning - ~20 minutes
Show the DLE off to your colleagues - one more hour

Outcome:

Total time spent: 2 hours
Total money spent (r5.xlarge, 200 GiB disk space for EBS volume + DLE Standard subscription): less than $2
The maximum number of clones running in parallel with default configuration (shared_buffers = 1GB for each clone): ~30 clones
Monthly budget to keep this DLE instance: $360 per month - same as for a single traditional RDS clone
