Introduction to VMware, VSphere 6.0

First, the basic concept of virtualization

1. What is Virtualization

Virtualization refers to virtualizing a computer into multiple logical computers through virtualization technology. running multiple logical computers at the same time on a single computer, each logical computer can run a different operating system, and applications can run independently of each other, providing significant productivity for the computer.

2. Why to Virtualize

1) need to be in a specific hardware and software environment to virtual another different hardware and software environment, and can break the level of dependence on the first grasp of the status quo.

2) Improve the utilization of computer equipment

3) Resolve hardware compatibility issues

4) Cost savings

3. The History of Virtualization

Propose concept :

The first presentation of the concept of virtualization was presented in June 1959 by a computer scientist, Christopher Strachey, in a paper published at the International Conference on Information processing (time sharing in large-scale computers), and discussed virtualization technologies.

Development technology:

Until the 1960s, IBM's operating system virtualization technology enabled mainframe resources to take full advantage of, and to launch, virtualization-enabled minicomputer. such as ibm360/40,ibm360/67,vm/370, etc.

Flourish:

Since the 1990s, VMware has pioneered the virtualization of the x86 server architecture and launched the first virtualization business software VMware Workstation on the x86 platform in 1999. Accelerating the pace of virtualization

Crowded

With the development of virtualization on the x86 platform, and its low cost, many vendors have joined the development of virtualization technology, such as virtual pc,parallels Workstation and VirtualBox under Windows System. But these end up being acquired by big vendors, but the subsequent advent of desktop virtualization, network virtualization, storage virtualization, Application virtualization, etc., has driven the wide application of virtualization technology.

4, the classification of virtualization

Since the virtualization of the proposed, there are many virtualization technology classification, there are many methods, but from the point of view of the use of virtualization, virtualization technology is divided into the following major categories:

Platform Virtualization

Desktop Virtualization

Server virtualization

Virtualization of resources

Network Virtualization

Storage Virtualization

Application Virtualization

Presentation Layer Virtualization

5, two ways of virtualization

Bare Metal Architecture Hyper-i

Hypervisor does not depend on the operating system to run directly on the hardware,

Alien Architecture Hyper-ii

Hypervisor as an application running on an already installed operating system

Good hardware compatibility,

6. What is cloud computing

Cloud Computing is a computational model that abstracts resources such as computing power, storage, networking, and software into services , so that users can enjoy it remotely over the Internet, paying in the same way as traditional public service facilities. requirements, ease of access, dynamic change, and unlimited virtualization scalability are some of the key features of cloud computing.

Different "clouds" correspond to different infrastructures. Here are three broad "clouds":

Platform as a service (PaaS)

Software as a service (SaaS)

7. The relationship between virtualization and cloud computing

virtualization is a specific technology implementation, such as: Server virtualization, Desktop virtualization, network virtualization, storage virtualization, etc.
cloud computing can be understood as a business model with private cloud, public cloud, hybrid cloud, etc.
virtualization Technology is one way to achieve cloud computing, but cloud computing is not just an implementation of virtualization

Ii. Introduction to VMware vsphere

VMware was founded for 1998 years, and 2003 storage maker EMC acquired VMware for $635 million, and in October 2015 Dell announced a $67 billion acquisition of EMC.

Correct reading method: "Micro-si-er-fei"

1. Introduction to VMware VSphere 6

VMware VSphere 6.0 is an industry-leading virtualization platform that enables users to confidently virtualize scale-out and scale-out applications, redefine high availability, and simplify virtual datacenters.

A highly available, resilient, on-demand architecture that is ultimately the ideal foundation for cloud computing environments

6.0 vs. 5.5 versions:

2. VMware VSphere 6 Components

VMware ESXi

The previous version of VSphere has ESX,

ESX: Virtual machine Platform hypervisor, ESX contains a VMware Kernel (virtualization Management Core) and a command-line service Console (VSphere 4.1 will be the last platform to contain the ESX version, Subsequent versions will only include ESXi)

ESXi (also known as vsphere Hypervisor): Basic capabilities with ESX, but ESXi only retains the management kernel (VMKernel) and no longer contains the service console (with VCLI or powercli to replace most of its features), so the volume is very small, Can be installed on embedded devices such as USB sticks (the free version of ESXi supports VMFS and VSMP only, and does not support some additional features.) ）

VMware VCenter Server

Virtualization Platform Management Center control system , with Windows and Linux editions,

VSphere Update Manager

vsphere Environment upgrades, patching tools,

VMware vsphere Client and vsphere Web client

vsphere Client,

VRealize Orchestrator(formerly vcenter Orchestrator)

Automation engine, tools for building workflows

VMware Data Protection

Data Protection

VSphere with Operations Management(purchase or purchase a kit separately)

Monitoring and management tools,
