Private cloud control has deepened my DevOps automation and strengthened security practices

For improvement, I feel the documentation available for setting up and creating infrastructure using Rackspace OpenStack could be enhanced, as I personally find the existing documents are not sufficient for new learners or beginners. We can also work on improving the user interface; the Horizon dashboard is functional, but compared to AWS, Azure, or Google Cloud, the UI feels somewhat dated. A more modern, intuitive interface with better navigation would enhance the overall user experience, especially for new users. Improving the documentation, including more real-world deployment examples, troubleshooting guides, and architecture best practices, would make onboarding much easier. Faster upgrades would also help; Rackspace OpenStack upgrades can sometimes be complex, so simplifying the upgrade process and minimizing downtime would assist organizations in maintaining their environments more easily. Additionally, improving monitoring capabilities would be beneficial, with advanced monitoring and analytics dashboards providing administrators deeper visibility into performance, capacity, and potential issues without relying heavily on third-party tools. Adding more managed services, similar to what public cloud providers offer, could reduce operational overhead while still allowing customers to retain the flexibility of a private cloud. Lastly, integrating AI could be valuable, with AI-driven recommendations for capacity planning, security monitoring, and automated troubleshooting improving platform management.

Managing mixed RAID workloads has improved data protection and delivers strong performance

VMware vSAN can be improved in certain areas. In cases involving our large data stores with large VMs, we experience some latency, not during normal operation, but during database backup operations. We observed latency due to buffer issues from the top-of-the-rack switches. These issues are mostly network-related because all storage data traffic travels through the network. I have recently used Nutanix, and I observed that Nutanix provides better performance than VMware vSAN due to its data locality features. VMware vSAN is now providing data locality, but we did not use that option. If VMware vSAN provides additional features in the next release, such as the VM balancing feature called DRS on the cluster that VMware previously had, it would be beneficial. With DRS, VMs can move easily from one node to another within the same cluster. Nutanix does not provide that flexibility. When placing a VM on a cluster in Nutanix, the placement uses a balancing component. After that, the VM remains on the same host. If any contention occurs on the CPU or memory side, the VM stays in place until contention happens. If issues occur, the VM migrates to another host while transferring all objects to the same host. This is how their data locality is maintained. When a VM moves to any host, it moves with all VM objects. VMware vSAN does not currently offer this option. If a VM moves to another host, it accesses the disk object through the network, which increases latency. VMware vSAN now offers an option to select data locality, but it does not function like Nutanix. This is why some latency remains. If VMware vSAN can improve this feature, it would be very helpful and VMware would regain its top position.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Administrators are very comfortable with the functionality and services OpenStack offers."

"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."

"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."

"Rackspace OpenStack impacted my organization positively in that the drive helped me keep files in an organized folder, and obviously we needed email addresses to be able to communicate with each other and for outsiders to be able to email us."

"It was a very flexible and scalable solution. It was very useful because we were not dependent on a single vendor's solution. Increasing the number of machines or changing the hardware configuration was very easy."

"The open-source nature of OpenStack provides significant value."

"There are many services that can be directly used which are not available in VMware."

"Rackspace OpenStack has positively impacted my organization by bringing us much closer to our customers based on the supportability this platform provides, and it has unique features which are very useful for our customers."

More Rackspace OpenStack pros

"As a function of our core business, it's a sought after tool that helps us provide analytical support across a wide spectrum of client needs."

"It's easy to use."

"The technical support has been great from VMware vSAN."

"We have definitely seen value, especially in performance."

"The most valuable features are scalability and speed."

"vSAN has just one datastore. so customers do not need to think where to put their VMs, how to design the physical disk RAID, the LUN size, the LUN mapping, etc. when they use NetApp/EMC/HDS or other storage systems."

"Being able to deploy multiple applications with virtual servers is the most valuable for us. The capacity of the system is quite constant so it's got some of the good features."

"I think you should try it – it's really stable and valuable and helps to drill your costs down."

More VMware vSAN pros

Cons

"Rackspace OpenStack can be improved because it wasn't clear that you have to cancel 30 days before; otherwise they charge you for the month."

"VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."

"In terms of what needs to be improved, I would say the support. Rackspace might have some good support but the open source OpenStack doesn't have support because there are too many versions coming and too many people are customizing it."

"The deployment process could be easy."

"I cannot comment comprehensively on how Rackspace OpenStack can be improved, as I do not find that much difference; however, some areas can be improved, such as support for OEMs deploying highly specialized real-time telecom and media workloads."

"It could use more examples in different languages (API use cases)."

"The line migration is a problem."

"The pricing of Rackspace is quite high in the Vietnam market."

More Rackspace OpenStack cons

"Integration could be better."

"I would like to see replication as part of it. I would also like to see direct file access, being able to run SIF shares and NFS and the like. I think that would be critical to continuing the use of it going forward."

"In cases involving our large data stores with large VMs, we experience some latency, not during normal operation, but during database backup operations."

"The ROI is negative, the capex is OK, but the opex is outrageous."

"We have encountered some scalability issues and got a couple of performance tickets."

"We do see weird things crop up every now and again. It will say that a drive gets kicked off even though it's fine, and we have to re-add it."

"VMware vSAN could improve by having faster reload time and a single point of failure. Resynchronization of many hardware could be better. If you have an outage of a disc or a full system, the replication time is too slow. This has room for improvement."

"I'm not happy with the VMware support. There are so many delays attributed to different reasons, like when you transfer the case from one engineer to the other, the second engineer is not aware of what the first engineer has done, so we need to update the second engineer from the beginning."

More VMware vSAN cons

Pricing and Cost Advice

"I use it as an open-source tool."

"The pricing is low."

"I have been told that if I used VxRail it would be cheaper than the system we are using now with buying the products separately. The solution is expensive overall."

"Due to recent changes in VMware's licensing approach by Broadcom, the cost has increased significantly, making it less attractive from a cost perspective."

"I would rate the licensing model a three out of ten, where one is expensive, and ten is cheap."

"The vSAN is somewhat expensive to license."

"Basically, vSAN is a license in addition to that of the classic VMware Vsphere, which is also mandatory."

"It is an expensive solution. There should be more flexible with licensing to allow small businesses the essentials of the solution's features."

"Clients have to pay for VMware vSAN licensing based on the number of CPUs. The purchases would be lifetime or perpetual, but you need to have support, e.g. the support is negotiated from one, two, three, or four years."

"There is a license required for this solution, it is a one-time payment. However, if they want support for the solution, it can be paid annually or for three years."
