Public cloud segment leaders projected to secure another 10% of market share by 2023

TBR estimates total public cloud market size was $165 billion in 2018. Microsoft (Nasdaq: MSFT) led the overall public cloud market, while Amazon Web Services (AWS) (Nasdaq: AMZN) maintained a strong lead on the IaaS segment and Salesforce (NYSE: CRM) delivered enough growth to sustain a top-three position in both SaaS and PaaS market share. Microsoft and AWS are expected to jointly compose nearly 40% of the public cloud market over the next five years, while Adobe (Nasdaq: ADBE) and IBM (NYSE: IBM) — fourth and fifth, respectively, in total public cloud revenue in 2018 — will fall out of the top five by 2023 due to adoption headwinds and an inability to convert established enterprise relationships into revenue growth while Alibaba (NYSE: BABA) and Google (Nasdaq: GOOG) take share.

Trend to watch

An increase in multicloud environments will position some vendors to take segment leaders’ market share.

“In the SaaS market, Microsoft Adobe and SAP have joined forces under the Open Data Initiative to challenge Salesforce’s single vendor suite,” TBR Senior Analyst Meaghan McGrath said. “Meanwhile, Alibaba and Google will embrace their role, providing additional PaaS and IaaS services to enterprises that made early investments in AWS or Microsoft.”
