This is the repository for data released from Huawei Cloud's public and private serverless cloud platforms. The data is analyzed in two papers:
-
EuroSys 2025: Serverless Cold Starts and Where to Find Them
-
ACM SoCC 2023: How Does It Function? Characterizing Long-term Trends in Production Serverless Workloads
- Links to our paper PDF: ACM Library, arXiv, GitHub
- Conference video presentation: YouTube, BiliBili
The datasets used in our papers can be downloaded at the links below.
- Huawei Public cold start traces 2025 contains time series of 19 metrics per function over 31 days for 5 regions, as well as per-event tables of requests and cold starts.
- Huawei Public and Public traces 2023 contains time series of 8 metrics per function over 235 days at per-minute and per-second granularity for two serverless platforms.
In some cases, you may not need all files in a zip folder. You can use 7zip to drag and drop the desired files or directories without extracting the entire archive.
To get started using the datasets, look at our notebooks for tips on how to load files and visualize the data.
