Linux Virtualization in Cloud Computing

Virtualization is one of the critical factors for the technology world. It consists of multiple benefits from running various VMs, delivering services, and also developing security. So Cloud Computing is also built by adopting Virtualization Technology. Let us learn about Linux virtualization.

What does Linux Virtualization mean in Cloud Computing?

Linux Virtualization is one of the processes the user can add, execute and maintain multiple virtual machines on top of the Linux Operating System. It permits the hardware consolidation and software resources that are utilized in Linux OS. This also permits them to share and get divided across multiple virtual machines along with their associated process.

In Cloud Computing, Virtualization can help deliver the virtualized environment at a reasonable cost and higher efficiency.

One of the main advantages is that users can operate Windows, Mac, OSC, and several other virtual machines to implement Operating Systems apart from Linux.

Top Linux Virtualization Software

Linux Virtualization Software is divided into three sections.

1. Open Source Linux

  • Proprietary Linux Virtualization Software
  • Parallels Virtuozzo Containers
  • Tasks performed by Parallels Virtuozzo Containers
a. OpenVZ

OpenVZ is one of the Operating systems whose functions are dependent upon the Linux Kernel.

b. Xen

Xen is one of the famous monitors which can work with 32/63 Bit Intel/AMD and PowerPC 970 architectures. It permits the implementation of several guest Operating Systems simultaneously on the same Hardware Environment.

Xen is furnished with the most famous Linux Distributions like

  • Debian
  • CentOS
  • Fedora
  • Ubuntu etc

2. Kernel-Based Virtual Machine (KVM)

It consists of the Linux Virtualization infrastructure, which has the role of supporting native Virtualization. It utilized Intel VT or AMD-V. KVM can work and handle multiple guest Operating Systems including Linux, BSD, Solaris, and Windows.

3. Proprietary Linux Virtualization Software

a. VMware ESX and VMWare Server

This is ranked as the initial stage of Linux Virtualization Server software. It is an advantage for the organization as it offers a data center Virtualization feature. It can authorize an organization to run guest Operating Systems like Solaris, Windows, Linux, and many other Operating Systems.

b. XEN

XEN offers commercial applications along with some remarkable developments.

i. Citrix XenServer

Citrix XenServer makes use of an open douce Xen Hypervisor, which has the role of dividing the server into two logical sections. It is one of the popular technologies that offer Low overhead along with crucial performance.

ii. Oracle VM

It is also built using the open-source Xen Hypervisor technology, which can handle both Windows and Linux-based guests. It consists of a combined Web browser-based management console.

iii. SunxVM

SunxVM runs by using a bare-metal hypervisor which the Solaris Environment on x86-64 systems inspires. xVM is developed based on Solaris and Sun’s Logical Domain.

c. Parallel Virtuozzo Containers

Parallel Virtuozzo Containers offers Virtualization on the Operating system, specially designed for massive servers that work in the homogenous environment and data centers. They can quickly get compatible with IA-64, x86, and x86-64 platforms.

Tasks performed by Parallels Virtuozzo Containers

1. Management

Accurate tools and templates are utilized for automation tasks, multi-container, and multi-server administrator.

2. Proper Partitioning

Offering a server partitioning into several can be performed by Parallels Virtualized Containers with complete functional abilities.

3. Security

When the server gets divided, all sections will be secured and completely functional. Additionally, users can run several Linux Distributions in the Parallels Virtualized Containers.

Advantages of Linux Virtualization

1. Cost-effective

Organizations always think of reducing their expenses and maximize their profits along with maintaining customer satisfaction.

Linux Virtualization is one of the famous, cost-effective techniques that will help to aim at higher-earning and customer satisfaction.

The license fee gets minimized in Linux Virtualization as the Hardware resources installation is minimized.

2. Increased Availability

By adopting Linux Virtualization, organizations can achieve maximum uptime and availability to their clients. It offers easy storage, migration, and backups.

One of the key advantages is that if any virtual server fails, other servers will be ready to serve.

3. Optimal Utilization of Resources

In Virtualization, it takes a minimum amount of time to set up and maintain the servers. Setting up and managing the physical servers require technical experts; organizations must also invest in infrastructure.

4. Virtual Servers can reside in small spaces.

Physical Servers continuously require a high volume of electricity and the cooling device, which results in hazardous for the environment as it causes harmful emissions. These will be erased in Virtual Machines.

5. Easy Migration

Linux Virtualization requires a virtualized environment that must be easily transferable from one location to another. Thus, in a Virtualized environment, the relocating task is easy.

6. Reduced Management

As the physical Hardware servers’ quantity is low, the time and money invested in management tasks will be minimized.

7. Flexible

Linux Virtualization offers flexibility to users by building a new environment on the existing physical box by using various applications modified with Xen Virtualization. It is more beneficial to fulfill the client requirement, and thus, it makes the clients more responsive depending on the business requirements.
