    Study Notes

    Virtualized Data Center

    • A virtualized data center is a data center with some or all of its hardware virtualized, including servers, storage, network devices, power distribution systems, and cooling systems.

    Benefits of a Virtual Data Center

    • Provides flexibility and scalability
    • Reduces overhead by allowing additional capacity to be leased as needed, decreasing maintenance costs
    • Simplifies management by transferring infrastructure responsibility to a cloud provider
    • Improves resiliency by guaranteeing high availability and accessibility
    • Enables business focus by allowing companies to focus on core objectives without managing physical infrastructure

    Virtual Data Center Components

    • Virtual machines (VMs): software-based emulations of physical computers that run on a hypervisor, with their own operating system, applications, and virtual hardware resources
    • Virtual networking: enables communication between VMs within the VDC and with external networks, including virtual switches, routers, and load balancers
    • Virtual storage: a centralized, software-defined storage pool for VMs, allowing for flexible allocation of resources and features like snapshotting, replication, and data deduplication
    • Hypervisor: the foundation of a VDC, allowing multiple VMs to run on a single physical server, enabling efficient utilization of hardware resources
    • Management and orchestration tools: control and automate the provisioning, configuration, and monitoring of VDC components
    • Security components: virtual firewalls, intrusion detection and prevention systems, and access control mechanisms to protect the VDC and its workloads from unauthorized access and cyber threats

    Data Center Network Topology

    • Multiple links are used to eliminate single points of failure in the network topology
    • Introducing additional links creates loops in the network topology, which can be dealt with using spanning tree protocol, IP layer routing, or hybrid L3/L2 switching networks
