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
