Pricing and ROI: IBM PowerVM offers robust pricing reflecting its enterprise capabilities and steady ROI. Spot by Flexera emphasizes immediate cost reductions, justifying its premium through cloud cost savings for dynamic environments.
The return on investment is substantial, though other platforms may offer a better ROI, primarily due to lower costs involved in setup and maintenance.
If calculated over a five-year period, IBM PowerVM is 30 to 40% more cost-effective than physical servers despite initial costs seeming high.
By using Spot by Flexera across a year, we were able to save more than 500,000 euros.
Our technology predicts demand, selects the cheapest instance mix, sizes the workloads appropriately, and scales it automatically based on policy, resulting in significant savings by reducing manual work and enhancing our flexibility, which has helped accelerate our deployments.
I cannot share the exact number, but I can share the figure that my EC2 and EKS compute cost reduced by around 65 to 75% with Spot.
IBM provides strong support.
IBM offers excellent customer support.
IBM's technical support is outstanding, with seamless global coordination and prompt resolutions.
I would rate the customer support a nine out of ten.
We did not have to use it many times, but the few times that we did use it, it was very fast and very useful.
An IBM server can handle up to sixty-four terabytes of RAM.
The product is scalable due to PowerVM's virtualization features, such as shared processor functionality and partition mobility.
I think IBM PowerVM uses a 'pay as you grow' model, allowing customers to scale their resources as needed.
It is also a very easy tool to connect to different data sources and different servers since it is open source.
Spot's scalability is quite good, and it can be expanded to multiple environments.
The stability of IBM PowerVM is exceptional, as industry reports have named IBM Power and Z as the most stable platforms globally for 15 consecutive years.
Our clients in India using Power Servers have been running their servers for the last four to five years without any reboot.
The product operates reliably, and following IBM’s best practices ensures robust stability.
In Spot by Flexera, we could see both computers, the old and the new one, but the system was not recognizing that the old one was no longer being used.
We have a strong relationship with IBM, which aids decision-making in transitioning clients from mainframe to other platforms.
PowerVM should integrate some capabilities of VMware vCenter to improve its management features.
From a product perspective, I would like to see faster certification of open-source products on IBM Power Systems.
Continuously making advancements based on customer feedback.
Spot could be improved by adding features that help identify data to optimize storage costs by detecting datasets within our environment based on criteria such as age and usage.
More guided onboarding would help teams adopt advanced features faster.
Pricing is a concern in Argentina due to the higher cost of mainframe solutions.
PowerVM itself is free with the purchase of an IBM server.
While initially costly, the ROI over five years proves IBM PowerVM is cost-effective, resulting in a 30 to 40% reduction in costs compared to a physical setup.
The pricing is reasonable and convenient, and the value it offers is completely in line with what I am spending.
I was aware of different pricing, setup costs, and licensing across the company.
Features like partition mobility enhance the machine's capabilities, making it an ideal tool for virtual environments with reliability, availability, and serviceability.
IBM PowerVM is performing very well in supporting complex workloads.
PowerVM excels in efficiently managing all systems and environments, including development, UI, and production.
Spot's automated cost optimization works by continuously analyzing the workload and applying policies to minimize cloud spend without sacrificing performance.
The fact that it can mix dozens of instance families dynamically is something which the AWS native autoscalers simply cannot do.
Spot helps us detect such changes within AWS at least one hour prior, allowing us to have a mitigation plan in place and host other servers within the same setup to avoid impacting the application.
