(20)Cloud computing service providers are one category of digital infrastructure covered by Directive (EU) 2022/2555. The Union Oversight Framework (‘Oversight Framework’) established by this Regulation applies to all critical ICT third-party service providers, including cloud computing service providers providing ICT services to financial entities, and should be considered complementary to the supervision carried out pursuant to Directive (EU) 2022/2555. Moreover, the Oversight Framework established by this Regulation should cover cloud computing service providers in the absence of a Union horizontal framework establishing a digital oversight authority.
