Nelson Marcos - PeerSpot reviewer
It's easier to provision VMs than other solutions and you can customize it to integrate with load balancers
My teammates have complained about the upgrade. The source code had massive files that had to be merged with our own development to upgrade to the latest version of CloudStack. It was quite painful for them. CloudStack could add some cost management tools to give me some control over the costs associated with the number of users of my services.

Senior Technical Specialist appreciates intelligent workload management, strong support, and scalability
The best features of IBM Spectrum Computing are common across many of their storage products. The software is solid, meaning that the code is stable. They take business seriously, which is what IBM stands for - International Business Machines. They always maintain a business-oriented approach in their software development. It's not simply clicking through interfaces; in IBM software, they consider their actions, process flows, and workflows around business processes. It requires understanding IBM and their methodology, as the software operates accordingly. I have utilized IBM Spectrum Computing's intelligent workload management feature. We use Insights, which is connected to the cloud. This provides AI capabilities for analyzing the configuration, offering smart recommendations on new code, warning about bugs in current code, and suggesting configuration improvements through its advisor tool. The predictive analytics feature in IBM Spectrum Computing enables optimal software performance through Insights. However, being a storage administrator requires foundational knowledge and understanding beyond these tools. For troubleshooting, it's efficient in spotting bottlenecks, but understanding the terms and metrics is essential as it provides answers that need interpretation.

Quotes from Members

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

Pros

"I have been impressed by CloudStack's most recent updates around Kubernetes. In particular, they have worked with Kubernetes to support the Cluster API, and you can now easily integrate Kubernetes into CloudStack and get access to a lot of good features."
"The platform is very simple to scale-out.​"
"You can manage infrastructure with a few people, since product is monolithic. We had three engineers (storage, virtual, Linux admins) only. Also, CS supports different flavours of hypervisors."
"The initial implementation process was quite good."
"​You can build your own cloud and make it customizable with APIs​."
"When compared to OpenStack, CloudStack is also an open-source platform that is continuously improving its features and capabilities with each new version release. Having worked with CloudStack 4.7, 4.14, and most recently, 4.17, I have noticed significant enhancements in the platform's features and customer experience, such as the introduction of a new user interface in the latest release. Notably, the latest versions have made major improvements to VM live migrations, making them more efficient and effective."
"The structuring of the components and isolated environments helped us when using parts of the framework at different levels of product development."
"CloudStack helped us showcase our features through process visualization and functional solutions."
"The best features of IBM Spectrum Computing are common across many of their storage products."
"IBM's ability to cluster compute resources is impressive, with built-in support for scenarios like VR and active-active configurations,"
"I have utilized IBM Spectrum Computing's intelligent workload management feature through Insights, which is connected to the cloud."
"The comparison was challenging, but the IBM Spectrum Scale offered a balanced solution. Our engineers rated itsanalytics capabilities equally high as Pure Storage. For workload management, Spectrum Computing provided effective solutions that met our needs. Workload management is part of a complete solution that uses different tools. There were the cloud and HPC parts; within HPC, there were parts like liquid cooling, simple computing, storage, and orchestration. The orchestration team handled the workload management."
"This solution is working for both VTL and tape."
"The most valuable feature is the backup capability."
"The most valuable aspect of the product is the policy driving resource management, to optimize the computing across data centers."
"Easy to operate and use."
 

Cons

"The numerous, multi-layered drill-down menus make it difficult to find one simple knob to turn."
"The product does not have an easily implementable payment gateway."
"I think that container technology in CloudStack is an area that needs to be improved."
"The Windows hosts do not get their hostnames from cloud-init."
"The number of contributors to this solution is relatively small compared to other solutions. However, if more frequent users of CloudStack contribute to the open-source community, it will significantly enhance the overall community experience and make it more useful for everyone involved."
"For time consuming operations like storage migrations, volume Snapshot restore and the like, we faced issues like MySQL operations timing out and status update failures. Those areas needs improvement."
"The main reason why we started looking for another solution: backups, replication, HA, and dependency on secondary storage. CS is quite sensitive for infrastructure, and any kind of network disruption between CS and secondary storage leads to VM hanging."
"There are some minor things that can be improved even more such as, perhaps, a bit more polishing on the GUI side to catch up with the API possibilities (which are really extensive) but otherwise nothing critical."
"This solution is no longer managing tapes correctly."
"Lack of sufficient documentation, particularly in Spanish."
"We'd like to see some AI model training for machine learning."
"In Pakistan, IBM's disadvantage is the lack of OEM support and presence."
"The deduplication software isn't quite up to speed with the market."
"Spectrum Computing is lagging behind other products, most likely because it hasn't been shifted to the cloud."
"SMB storage and HPC is not compatible and it should be supported by IBM Spectrum Computing."
"IBM's sales and support structure can be challenging."
 

Pricing and Cost Advice

"The solution is open-source and free."
"It is a 100% open-source solution needing just an Apache license. Also, there are no hidden fees to be paid."
"There is no license, so the product is free unless you are buying professional technical support services."
"As far as I know, CS is still free of charge. If you want to pay some money, Citrix Cloud Platform is based on CS, I think. As for hypervisors – everything as usual, you need to pay for VMware and vCenter. As for XenServer, recently they changed the free feature list, so you may need to pay some money to get useful features like XenMotion."
"CloudStack is an open-source product."
"The Apache CloudStack is open source, so you do not have licenses to purchase."
"​Give an effort to planning. If possible, contract a specialized consultant company for the initial setup and knowledge transfer.​​"
"CloudStack is an open source solution, so you don't need to pay anything for it. When our company develops something specially for CloudStack, it is donated to the Apache Software Foundation and provided to anyone that wants to use it."
"This solution is expensive."
"Spectrum Computing is one of the most expensive products on the market."
