Cloud Computing Fundamentals

Understand IaaS, PaaS and SaaS, compute, storage, databases and networking, identity and security, monitoring, backups and cloud costs — with a complete sample architecture. Cloud computing powers almost every app you use, yet the jargon makes it look harder than it is. This book explains the cloud from the ground up in plain language — service and deployment models, compute, storage, databases and networking, regions and high availability, identity and least privilege, hosting with CDN and DNS, monitoring and disaster recovery, cost control and shared responsibility — and ends with a complete sample architecture you can understand line by line.

Who this eBook is for

Students, IT beginners, developers, support engineers, small business owners and managers who want a clear, vendor-neutral understanding of cloud computing on AWS, Microsoft Azure and Google Cloud before they build, buy or start a cloud certification.
