Virtualization is not a new concept. The web hosting industry leveraged server virtualization to create virtual servers and launched a new type of efficient hosting services – VPS Hosting. This is done by using a virtualization program called a hypervisor. It helps the host divide the physical web server into several virtual servers, each with dedicated resources, account isolation, and complete root access. There are various ways in which the web host can create VPS Servers, including KVM, Virtuozzo, and OpenVZ. Today, we will talk about hypervisors and compare these three hypervisor applications.

What are KVM, Virtuozzo, and OpenVZ?

  • KVM or Kernel-based Virtual Machine is a technique to create virtual servers that run on the kernel of the Linux operating system. This technique converts the kernel into a hypervisor to create virtual servers.
  • Virtuozzo is a container-based virtualization solution allowing hardware sharing using an abstraction layer. It creates containers that simulate a server. It is not a hypervisor but operates in a mix of the kernel and userspace with the proprietary kernel.
  • OpenVZ is also a container-based virtualization application for Linux. It is the basis of Virtuozzo and helps create virtual servers.

Difference between KVM, Virtuozzo, and OpenVZ

Let’s look at the features of KVM, Virtuozzo, and OpenVZ to understand the differences better:

Operating System support

  • KVM – Linux, Windows, and customized operating systems
  • Virtuozzo – Linux and Windows operating systems
  • OpenVZ – Linux operating system only

Kernel Versions

  • KVM – The virtual machines created by KVM can each run a different kernel version than the hypervisor
  • Virtuozzo – It runs a single kernel as the core. This core is sent to multiple distributions, that help create stand-alone entities.
  • OpenVZ – The containers created by OpenVZ have the same architecture and kernel version as the hypervisor. Hence, it has a lower overhead on the hypervisor.

Memory Distribution

  • KVM – This has a hard memory limit. Therefore, it offers a stable distribution of resources.
  • Virtuozzo – If the server does not have adequate RAM, then Virtuozzo can fail since it depends on virtual RAM. If it runs out of RAM, then it kills the processes.
  • OpenVZ – In OpenVZ, the memory that is not used by one container can be used by the other containers.

While as a site owner, you need to focus more on the features offered by the VPS Hosting plan, understanding the architecture and techniques used for creating the virtual servers can help you understand what to expect from the virtual servers. Talk to the hosting company and try to understand these details to make an informed decision.

Summing Up

VPS Hosting offers a range of benefits to websites since it is based on a virtual server that has dedicated resources, account isolation, and complete root access. The way the host creates the virtual servers can impact the performance of the virtual server and the hosting service. Hence, if you have some technical know-how, try to understand the type of hypervisor used by your provider –  KVM, Virtuozzo, or OpenVZ, to buy the right hosting plan for your site. Good Luck!

 At the time of choosing web hosting providers, the people need to consider several kinds of points so that the best web hosting provider is always chosen and all the needs are easily fulfilled.

When it comes to security vulnerability, it can be an error, bug, fault, flaw, or weakness in the software design, architecture, code, or any implication that can be easily exploited by cyber attackers. When a software fault, error, weakness, etc. in any software application, design, etc. is left unattained, it can lead to security vulnerabilities or cyber-attacks. There are 3 major types of security vulnerabilities that are given below, based on their nature of weakness:

  1. Porous defense vulnerabilities- This is one of the most common security vulnerabilities one can come across in the given software. In the list of 25 security vulnerabilities, 11 of them will involve porous defense vulnerability. There are many defensive techniques available such as encryption, authorization, and authentication. These techniques are useful when applied and used correctly but, when these are misused, abused, or used incorrectly they can lead to security vulnerabilities. The lack of these basic defensive techniques of missing encryption, authorization, and authentication can lead to major cyber threats.
  2. Vulnerabilities involving insecure interaction between components- Even though the insecure interaction between components category is not very common among security vulnerability, it’s a quite dangerous one. One can say, it is one of the least wanted software errors or vulnerability by all. It involves major cyber threats like SQL Injection, Cross-Site Scripting, and Open Redirect. 
  3. Risky resource management vulnerabilities- In a basic sense, resource management include creating, using, transferring, and destroying system resources such as memory. Proper and secure management is necessary for effective and safe application defense. The different types of risky resource management security vulnerabilities are related to the ways that the software mismanages the resources. The security vulnerabilities in these categories range from simple Buffer Overflow and Path Traversal to more serious and complicated issues like Inclusion of Functionality from Untrusted Control Sphere and Use of Potentially Dangerous Functions. 

All these types of security vulnerabilities have one thing in common. They are related to how the data is sent and received between separate programs, threads, modules, processes, components, and systems. To avoid and defend these vulnerabilities, there are two important strategies:

  • You must be thorough with what inputs you are using and make sure that it comes from a good source.
  • You must be well aware and make sure to use those inputs properly for their intended purposes.

Hence, it’s necessary to know about these security vulnerabilities and take the necessary steps to protect your system.

At times an eight-hour man-hour may not be enough to complete the work. In that case, it calls for working more than required or basically working overtime.  This is truer in a lot of engineering companies wherein it works based on the hours that the employee puts in.  Extension of deadlines may be exercised.  Even though many employees may not necessarily appreciate working overtime, if there is a requirement, there is no other way out.

This is when overtime pricing may be important to calculate, considering we are going through such Covid times where there is not much money inflow into the organisation.  The employees are expected to put in extra efforts for their work and there may be a scenario wherein the employee may not be in a position to shell out extra money. So this calls for understanding on the part of the employees.

 Especially during holiday times, there are chances that a lot of workload may be pending since this is the time when employees may go on leave.  Many employers also may not want to burden the employees with too much work since they definitely would not want to shell out extra money.  In such cases, they will have to talk it out to the employees about giving them some extra wages for the extra time they put in.  Check out if the log records are correct and the timesheet is complete. For this purpose, there are multiple software that can be used such as the leave or time-off softwares.

Click on the website and get to know more about us. A good monitoring software provides complete details about the overtime that may be required for specific tasks. The time that is going to take, calculation of employees overtime and last but not the least, the time tracking software.  The overtime rates may differ from one country to another. Hence employers would have to take the right decision when it comes to pay, tracking the worktime of employees and also compensating them adequately for their efforts without any compromise on the extra pay.

Many of the IT industries and corporations make sure to implement the time tracking solutions for their business to measure the work time or man hours keyed in by the employees. Empmonitor is the answer to those time tracking solutions.  It automatically logs the employees work activity, timing thereby providing a chart about their productivity. Even basic details like time of login, logoff, time when the employees are not at their workstations and so on.
