Moving to mainframe can be cheaper than sticking with VMware: Gartner
Gartner analyst Alessandro Galimberti suggests that for some organizations, migrating from VMware to an IBM mainframe could be more cost-effective than adopting Broadcom's licensing model. Mainframes offer built-in capabilities like high availability and data synchronization, reducing complexity for developers. While not suitable for all workloads, mainframes are well-suited for stable, mission-critical applications and large-scale Linux VM environments.
- ▪VMware users may find IBM mainframes cheaper than adopting Broadcom’s full Cloud Foundation stack.
- ▪Mainframes provide built-in high availability and data synchronization, reducing application development complexity.
- ▪The IBM z/VM hypervisor enhances Linux performance and enterprise readiness on mainframe systems.
- ▪Mainframes are ideal for long-term, mission-critical workloads requiring backward compatibility.
- ▪AI workloads may also benefit from IBM’s updated Spyre accelerators on mainframes.
