Virtualization Fundamentals With VMware vSphere Example

Explore how traditional data centers deploy servers by installing dedicated physical machines in racks. Demonstrate why the one server per application approach results in numerous physical servers in server rooms.

Explore why traditional networks use a 1 to 1 ratio and assess installing multiple applications on one server, including the potential drawbacks of consolidating workloads.

The video demonstrates drawbacks of hosting Active Directory, DNS, DHCP, web, email, and SQL Server on a single server: failure disables all services and performance degrades.

Adopt a one-to-one ratio by deploying a dedicated physical server for each application, with services installed on separate servers to improve performance and fault isolation.

Explore the drawbacks of a one-to-one server-to-application model in traditional data centers. Discover costs from power, cooling, cabling, space, and staffing, plus underutilized resources.

Explain why the data center uses a one-to-one ratio to run a separate operating system for each application—Active Directory, DNS server, web server, and email server—to boost performance and availability.

Overcome traditional data center drawbacks by running multiple operating systems on a single physical server. On top of these operating systems, you can run different applications at the same time.

Discover how server virtualization lets a single physical server run multiple operating systems as separate virtual machines, each with its own OS and applications, via a hypervisor.

Explore virtualization history from IBM mainframes in the 1960s to VMware's x86 virtualization, highlighting architecture differences, underutilization issues, and why adoption accelerated.

Describe VMware as a software company that develops virtualization software and cloud computing solutions, founded in 1998 and launched in February 1999. Introduce VMware Workstation, first product, in May 1999.

Discover how VMware became the first to invent virtualization for the x86 platform in 1990, addressing underutilization and other issues.

Explore VMware products that enable server, desktop, network, storage, and application virtualization, with vSphere as the key platform for virtualizing servers.

Discover vSphere, a VMware product that virtualizes x86 servers, and explore its components—ESXi, vCenter Server, VM motion, high availability, all tolerances, and vCenter Single Channel.

Explore how hypervisor software sits on a physical server to create multiple virtual machines, each running its own operating system and applications, powered by Esx hypervisor on x86 architectures.

Explore hypervisor types, comparing type one bare-metal hypervisors that run directly on server hardware with type two hosted hypervisors that run on an operating system.

Explain type 2 hypervisor, which runs on an operating system rather than hardware, enabling multiple VMs on a PC for testing, though slower and less secure than type 1.

Explore type two hypervisors from major vendors, including Oracle VirtualBox, Microsoft Virtual PC, and VMware Workstation, and understand their role in virtualization.

Explore type one hypervisor that runs directly on physical hardware, known as a bare metal hypervisor, creates multiple virtual machines, and directly accesses CPU, RAM, and storage resources.

Explore type 1 hypervisors from Oracle VM, Microsoft Hyper-V, and VMware ESXi, with ESXi as the core vSphere component that virtualizes x86 architecture.

Learn what ESXi is as a VMware type one hypervisor installed on a physical server, enabling multiple virtual machines with their own operating systems to run simultaneously.

See how a physical server with an ESXi host shares CPU and RAM resources with multiple virtual machines, forming the core of VMware vSphere.

Dcui is the ESXi direct console for initial host configuration (hostname, IP address, subnet mask, gateway) that requires physical access; advanced tasks require the VMware hosted client.

Use the VMware host client, a web-based tool, to create virtual machines and virtual switches on ESXi hosts and to manage storage and networking remotely.

Explore hardware and software requirements for installing ESXi by using VMware Workstation, a type 2 hypervisor, to create a virtual server.

Learn how to download and install VMware Workstation Pro on Windows, evaluate the software, follow installation prompts, locate the app, and create a virtual server before installing an ESX host.

Use vCenter Server to centrally manage multiple ESXi hosts from a single session. Install vCenter Server, configure its IP, and add hosts for web-based management.

Learn how vCenter Server centralizes management of multiple ESX hosts and enables advanced features such as vMotion, high availability, port tolerance, distributed resource scheduler, and kvm cloning.

Learn how vMotion migrates live virtual machines between ESXi hosts to keep services running during maintenance, enabling seamless transitions without downtime.

Learn how live virtual machine migration preserves service continuity during server-to-server moves, a virtualization technique VMware calls motion, framed as v magic by the presenter.

Migrate live virtual machine files from one storage to another during maintenance or upgrade using storage vMotion.
