Kubernetes primer: The technology and its market, 451/S&P, August 2022 - “Our tracking of revenue and market share for more than 80 different vendors indicates a Kubernetes market worth nearly $1.2 billion in 2022, rising to nearly $2.2 billion in 2026, representing an overall compound annual growth rate of over 17%” I think this is, like, kubernetes distros you buy…not public cloud? I’m not sure.
IDC, Dec 2021: “The worldwide container infrastructure software (CIS) market grew to $980.1 million in 2020 from $740.6 million the year before, representing 32.3% year-over-year growth.” They forecast it hitting ~$2.9bn in 2023. Their model includes private and public cloud kubernetes, with about a 80/20 split in 2022, with the 20% being public cloud.
