CloudClock is a cloud cost-optimization tool that automates scheduled start/stop of AWS EC2 servers. Just register your AWS keys and instances to stop wasteful charges at night and on weekends, with usage logs recorded automatically.
The story of launching a greenfield platform, built in-house from scratch to solve “always-on costs, manual mistakes, and untraceable operation history.”
A company operating many AWS environments — development, staging, production, and more. Servers tended to run nonstop, and cloud costs during unused hours had become a major burden.
Manual start/stop burdened operators and caused mistakes, so cost management needed to be systematized.
Servers kept running nights and weekends, so charges for idle time kept accruing.
Manual operations were error-prone, so instances were often left running.
Who operated what and when couldn't be traced, making audits difficult.
The more instances grew, the more management broke down, becoming dependent on individuals.
A cloud infrastructure operations company built an automated AWS EC2 scheduling platform in-house from scratch together with Amela. AWS key management, scheduler, automated start/stop, usage logs, and role separation are unified into a single admin console.

Auto-stop during unused hours. Minimize billable run time.
