This book brings together realistic, start-to-finish guidance for implementing cloud solution architectures in virtualized data centers. It introduces cloud "newcomers" to essential cloud concepts, and offers experienced operations professionals detailed information for setting up and provisioning Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS). Drawing on extensive experience working with leading cloud software vendors and integrators, the authors present comprehensive practical resources - including detailed operations flows, templates, and configurations. They offer best practices for managing cloud-based network, compute, and storage infrastructure, including a fully-tested management reference architecture. Coverage includes: * Public, private, and hybrid clouds and their components * Virtualization and cloud benefits and ROI analysis * Delivering cloud infrastructure services: from self-service customer requests to dynamic provisioning * Load balancing, firewalling, disaster recovery, and content delivery * Tracking, maintaining, and automating cloud network and compute resources * Managing server virtualization * Storage and I/O convergence in the data center * User portals, service catalogs, and customer self care * Service monitoring, billing, chargeback, and much more
