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

"Rackspace OpenStack positively impacts my organization by making processes easier since I do not need to manage all servers manually because it efficiently manages server operations and maintains proper data, which saves time."

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

"It created a reusable library with OpenStack features."

"The most useful opinion about Rackspace OpenStack is that it is very flexible, first of all, and the most important feature is that it is feature-rich."

"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."

"Rackspace OpenStack is stable and reliable, often compared favorably against other solutions."

"Customer Service: Top. Technical Support: Top"

"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."

More Rackspace OpenStack pros

"Its ease of use is most valuable. It is easy to configure, and there is a unified interface, which makes things slightly easier."

"Good performance, reliable and agile."

"The product’s most valuable features are performance and expandability."

"Without any doubts, I recommend this solution."

"Hands-down, if you need storage for VMs, vSAN is your option."

"The most valuable feature is fhe flexibility, the ability to move the machines around without hesitation."

"It is more stable now than it was before. It's not like it was in the first year. Now it is stable, and we trust it more."

"One of the design requirements was to meet 5,000 IOPS @ 4K 50/50 R/W, 100% Random, which from the performance testing below has been met."

More VMware vSAN pros

Cons

"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."

"The deployment process could be easy."

"It should have a single dashboard for cloud management and on-premises systems"

"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."

"So for the main stability, there have been a couple of issues that I've experienced."

"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."

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

More Rackspace OpenStack cons

"I am looking for more of a software-defined storage platform that uses different protocols, such as iSCSI, NFS, and CIS, and maybe also has an object as part of that. They should 100% make it more of a storage-based product where it is not linked just to VMware, and it also has NFS and iSCSI built-in at a scalable level. They should turn it more into a dedicated storage-as-a-service platform instead of just being built into the VMware kernel. Their level one and level two support is not at all good, and it should be improved."

"vSAN itself is a great storage platform, but one of the issues with it is that you have to be fully locked into the VMware package to use it. We're going to be deploying 72 Kubernetes nodes, and we're not going to buy VMware licenses for 72 of them, just so they can access vSAN. That's what we're using the Pure for. Opening it up so you could have vSAN as a data store, use it as a data lake, hit it with an NFS, S3 from outside the VMware ecosystem, would be great."

"I would like to see a little bit more documentation on the initial setup, and a little bit more explanation on the expandability: How to extend out your vSAN much more simply through the console because, a lot of the time, you have to do it through the command line."

"I lose a node in a cluster vSAN, which is also used as a cluster HA. I lose not only the storage part, which is not necessarily serious (depending on the configuration of the vSAN cluster), but on the other hand, I lose also a node of Compute, which can make things complicated quickly."

"VSAN currently has no data deduplication, and having such a feature would both be an improvement and provide a feature that Nutanix has."

"I would like to see some of the more traditional SAN functions that are out the now. I can list them: being able to Snapshot on the back-end, better de-dupe, and better compression. Those are the major ones."

"I'd like to see better integration with the Update Manager, with respect to firmware updates for hardware."

"The solution could be improved by having more filtered and multiple view volumes instead of a single view."

More VMware vSAN cons

Pricing and Cost Advice

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

"The pricing is low."

"I would like to use more advanced models of the solution but the price needs to be reduced. There are some extra costs for this solution including a license."

"It is slightly expensive. They can be more competitive in terms of pricing."

"ROI from an administrative perspective is clearly much better because I only have to deal with one user interface."

"The product's price is not high. The tool is available at a normal price."

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

"I'd love for this product to be cheaper."

"This is a cost-effective product. It's a bit cheaper than the other solutions."

"VMware vSAN is a little bit expensive and we pay annually. We have an educational institute where we receive discount prices from VMware. We do receive a reasonable discount but it's still expensive."
