Online Virtual Machines and How to Properly Manage Them

Innovations such as virtual machines saw the more efficient use of computer hardware. But exactly what is a virtual machine (VM)? It is a virtual computer hosted on a server that uses the server’s resources, e.g., memory, storage, and processor. In turn, a virtual machine can act as a host for other applications and have a different operating system from its host.When a virtual machine is based on the cloud, it is referred to as an online virtual machine.

This article discusses online virtual machines in more detail, including their benefits and use cases. It also aims to help you understand the role of a VM host server and the diverse types of virtualizations so that you can determine the right type of VM to use in your organization.

Selection of the Right Virtual Machine Type

When it comes to virtual machines, you should remember that a single host computer can host many virtual machines, a virtual machine operates in isolation from the other machines on the server as well as from the server itself, and virtual machines can be moved and copied between servers. When choosing the type of virtual machine for use within your organization, you should keep in mind that virtual machines can be configured in many ways, depending on your requirements.

If your priority is cost savings and your workloads include web servers, microservices, and containerized applications, the ideal virtual machine configuration is one that can scale out through the addition of more virtual processors and memory. If your priority is general-purpose workloads such as databases and web applications, you can opt for a mixture of price and performance by getting virtual machines capable of accommodating even more virtual processors and memory.

You can also have virtual machines that are optimized for heavier workloads such as database applications using large in-memory databases and performing data analytics. For even more demanding workloads such as machine learning, you can have virtual machines that are optimized for use with GPUs.

Benefits of Online Virtual Machines

There are numerous benefits of virtual machines, including:

In the case of online virtual machines, your cloud provider oversees their maintenance. This means that your IT teams can focus more on their core competencies, instead of spending precious time maintaining your virtual infrastructure. You also do not have to spend more money on hardware since online virtual servers are more efficient price-wise.

Use Cases for Online Virtual Machines

The more popular use cases for online virtual machines include:

Definition of a VM Host Server

A virtual machine host server is any computer that serves as a host for virtual machines. In turn, the virtual machines are called guest servers since they are “guests” of the host server. While a VM host server is often confused with a hypervisor, these two are entirely different from each other.

What is a hypervisor? It is the software that allocates the host server’s resources to the virtual machines that reside on the host.

In the case of online virtual machines, your cloud provider gives you access to the hypervisor that enables your IT team to allocate resources to your virtual machines. The hypervisor ensures the security of the communications between the VM host and your virtual machines.

Different Types of Virtualization

There are several virtualization types we have covered in our discussion, including:

Typical Features of Virtual Machines Online

Managing Your Online Virtual Machines with Parallels RAS

Parallels RAS is an all-in-one virtualization solution that enables efficient application and desktop delivery to all kinds of devices regardless of location. It supports the most popular hypervisors and hyperconverged solutions, including Microsoft Hyper-V, VMware ESXi, Scale Computing HC3, and Nutanix Acropolis, among others. Parallels RAS even supports the use of multiple hypervisors, while allocating resources from a single console.

Parallels RAS simplifies virtual desktop and application provisioning and deployment using its built-in VM templates. With its automated optimization capabilities, you can conveniently configure multiple virtual machines at the same time. You can also allow application access to guest machines at any time using VM pools.

Parallels RAS eliminates the need to add more hardware components to your IT infrastructure and allows you to secure your network with access-limit policies based on configurable parameters, including location, user type, group, and device type. It is also easy to learn as it comes with a user-friendly interface.
