In this modern world, nearly 95% of businesses have turned to cloud computing.
All their operations are carried out in the cloud or, as they say, a virtual environment.
The reasons why enterprises prefer virtualization are many. They include enhanced security and risk management, energy and cost savings, and centralized data management.
To achieve this, they use virtual workstations and infrastructure solutions like VMware.
So what exactly is VMware, and what does it do?
VMware is a software workstation that offers cloud computing software and services.
It allows users to own multiple virtual environments on a server or computer.
A single server or computer is used for many different virtual computer systems.
It can virtualize network adapters, hard drives, and video cards, among others.
If you are an organization seeking to set up multiple server systems without buying separate hardware, VMware will be helpful to you.
With VMware, you’ll manage multiple operating system and application workloads on a single server.
This way, you’ll manage your resources better. VMware creates a virtual machine similar to a computer where everything runs in its own window.
Why Look For VMware Alternatives?
Well, if there are other server virtualization software alternatives in the market, why not try them?
The economy is a critical factor that may influence your shift to a VMware alternative.
Since you’re looking for ways to cut costs, you’ll find a less costly alternative to use in place of VMware.
There are many up-front costs when it comes to virtualization. You have to buy the software, storage hardware, and pay for software implementation. These and many other costs can take longer to project your ROI.
VMware is expensive, prompting you to seek an alternative.
Hypervisor technology for VMware and other software may differ, especially when it comes to performance and benefits. For example, VMware is a bit challenging to navigate for first-time users.
Also, it doesn’t allow remote desktop protocol in its iOS version.
Why It’s a Good Idea to Look for Open Source Alternatives
Ideally, open source offers some fundamental benefits that proprietary solutions don’t. These include:
Speed: Open source enables speed due to its ability to work with community versions and improve them to ensure value delivery.
Agility and flexibility: Open source provides multiple ways of problem-solving.
Allows you to start small: Open source lets you start small using community versions before migrating to commercial-grade solutions as your business grows.
Open source is the future: Open source is definitely the future considering that mobile, web, and cloud solutions are all built on open source infrastructure.
Cost-effectiveness: Open-source virtual programs are very cost-effective compared to proprietary solutions and they empower you to start small and scale with time.
Now that you know the importance of evaluating your server virtualization software, let’s dig deeper into the various open-source VMware alternatives you should consider.
