Oracle VM VirtualBox and VMware ESXi compete in the virtualization software category. VMware ESXi appears to have the upper hand due to its enterprise-grade features and robust performance, which are ideal for large data center environments.
Features: Oracle VM VirtualBox is a free and open-source solution valued for its versatility and multi-platform support. It allows seamless integration with different VM images and provides flexibility for budget-conscious users. VMware ESXi offers high performance with advanced resource optimization and extensive integration capabilities, making it desirable for enterprise environments. Its clustering features and disaster recovery options are particularly noteworthy.
Room for Improvement: Oracle VM VirtualBox users seek enhancements in seamless file transfer and user interface, as well as better support for enterprise-grade features. Improved networking options and management stability are also desired. VMware ESXi users point out concerns such as high pricing and complex licensing post-Broadcom acquisition, along with a challenging setup process for advanced features. Suggested improvements include pricing strategy adjustments and quicker support response times.
Ease of Deployment and Customer Service: Oracle VM VirtualBox is known for its simple installation process, commonly supported by an engaged user community with limited direct support. VMware ESXi, although technically complex during deployment, benefits from robust customer support. However, users report mixed experiences, citing the need for better response times and clearer documentation.
Pricing and ROI: Oracle VM VirtualBox offers significant ROI due to its free availability, eliminating costs associated with licensing and server needs, which is particularly advantageous in non-commercial settings. VMware ESXi, though perceived as expensive, justifies its price with its advanced features, appealing to enterprises that prioritize high performance and virtualization robustness.
I did not perform any long-term stress tests, just for a couple of hours or days on every application.
The management burden decreased from a 20-person team to just five or six people providing 24/7 support.
Their forum and documentation is more than enough for technical support.
I rate the technical support from VMware as nine or ten out of ten.
In the last three or four years, we did not require any support from VMware engineers, indicating its high reliability.
Customer service and support are good; they are reachable, and at times remote support suffices.
The solution is scalable, allowing us to scale up or down regardless of infrastructure size.
vCenter Server can manage up to 1,000 ESXi servers within a single UI interface, allowing extensive deployment and management capabilities.
My customers are highly satisfied with its scalability.
The snapshot functionality in Oracle VM VirtualBox is effective for management purposes.
ESXi is stable, and our business operations depend on it year after year.
Stability rates a perfect 10.
Having some kind of API to maintain Oracle VM VirtualBox would be beneficial.
Providing a mobile application for remote access to ESXi servers would be beneficial.
It's not cost-effective for small users and creates a gap for alternatives, while favoring larger clients.
The cost of VMware ESXi is very high, especially after the acquisition by Broadcom, which led to price increases.
In the enterprise scenario, all software solutions, including Oracle VM VirtualBox, are expensive.
The product is very cost-effective, though not fixed, as pricing tends to fluctuate over time.
The solution is moderately priced, not exactly cheap yet not overly expensive either.
The pricing is expensive, with the cost for customers ranging from $10,000 to $20,000 yearly.
Its snapshot functionality helps with backup management.
The guest OS compatibility was tremendous because I used Oracle VM VirtualBox on Linux and ran Windows applications on top of that, working seamlessly.
Its capability to move virtual machines to physical machines is very efficient for our live environment.
As a level one or bare metal hypervisor, its unmatched scalability depends on underlying hardware, capable of managing large numbers of physical servers with one management platform.
vMotion is a daily used technology that allows us to have machines distributed across different sites while maintaining redundancy between the sites.
