Avoid Cold Starts With Scale-to-Zero Light Sleep

Koyeb has announced the public preview of Light Sleep, an enhancement to their Scale-to-Zero feature, designed to minimize latency for CPU workloads by reducing cold start times to around 200 milliseconds. This improvement builds on the original Scale-to-Zero iteration, which introduced Deep Sleep to enhance compute efficiency but resulted in cold starts that took between one to five seconds. Light Sleep enables serverless applications to wake up nearly instantaneously, making it ideal for large-scale deployments and real-time workloads. Available on Koyeb's Starter, Pro, and Scale plans, Light Sleep allows users to specify idle periods before transitioning to Deep Sleep, offering a more efficient use of resources. During the public preview, Light Sleep is free, but will later cost 15% of the normal per-second instance price. Interested users can activate Light Sleep through the Koyeb console by adjusting settings under the Scaling options.
