Cloud-based virtualization vs. on-site virtualization
Since the advent of virtualization technology, organizations have found it easier to manage their IT infrastructure by running multiple operating systems on a single server. Virtualization has also made it possible to migrate applications and servers across different hardware without any issue. However, the need to choose between cloud-based virtualization and on-site virtualization has become a daunting task for most organizations that are looking to implement this technology. In this article, we'll compare cloud-based virtualization and on-site virtualization to help you make an informed decision.
Cost
When it comes to cost, cloud-based virtualization seems to be the winner. Setting up an on-site virtualization infrastructure requires a significant upfront investment in hardware, software, and infrastructure support. In contrast, cloud-based virtualization can be accessed on a pay-per-use basis, which means that you will only pay for what you use. According to a recent report by Gartner, the cost of running an onsite virtualization infrastructure is about $6,000-$8,000 per year, while the cost of using a cloud-based virtualization platform is about $4,000-$6,000 per year.
Security
On-site virtualization offers better security than cloud-based virtualization. Because the servers are located in-house, it's easier to secure them against cyber-attacks. With cloud-based virtualization, the servers are located outside your premises and require an internet connection to access, which makes them more vulnerable to possible security breaches. However, cloud-based virtualization providers offer some security features that can help to mitigate this risk, such as firewall configurations, data encryption, and access control.
Scalability
Scalability is one of the main advantages of cloud-based virtualization. With on-site virtualization, you have to invest in additional hardware and infrastructure to accommodate increased demand. In contrast, cloud-based virtualization platforms can easily scale up or down based on your business needs. For example, if you need more resources during peak seasons, you can scale up your virtual machines using your cloud provider's dashboard. Conversely, you can scale down when demand is low.
Management
Cloud-based virtualization is easier to manage than on-site virtualization. With on-site virtualization, you have to manage the entire infrastructure, including hardware, software, and network components. In contrast, cloud-based virtualization providers take care of the hardware and infrastructure, allowing you to focus on managing the virtual machines. Additionally, cloud-based virtualization providers offer features such as automated backups, disaster recovery, and patch management.
Conclusion
Both cloud-based virtualization and on-site virtualization have their pros and cons. While cloud-based virtualization is more cost-effective and scalable, on-site virtualization offers better security. Before making a decision, it's important to consider your organization's resources and requirements. If you have a small IT budget, cloud-based virtualization may be the best option. If your organization requires higher data security, on-site virtualization may be the better choice.
