Managing a public cloud involves three main roles: end users, developers, and infrastructure/datacenter managers. It presents challenges including maintaining security and reliability across devices for users, resources for developers, and leveraging remote services like performance and availability for managers. Providers offer enterprises, mid-market businesses, and consumers core capabilities like shared infrastructure, billing, and monitoring. Managing the cloud requires provisioning, processing, storing, and securing data across servers, applications, and compliance frameworks. Developing an integrated service catalog and managing across technical and business domains with multiple partners is key.
