Senior Infrastructure Consultant at Infosys

Achieving seamless infrastructure management with optimized network and user access controls

I believe enhancements could be made in CloudStack, particularly in the management servers. I had the opportunity to collaborate with one of the Apache CloudStack developers, leading to the installation of additional agents for better information retrieval from hypervisors. We implemented configurations, ensuring consistency across hosts and VMs. We also utilized Ansible or YAML files to automate password upgrades during patching activities and database management, showcasing our customization efforts for improvement. For future releases, it would be beneficial if Apache enhanced CloudStack by integrating alerting systems directly. We've had instances where hypervisors experienced overloads without prior alerts, so proactive alerts within the tool would better prepare us for addressing issues swiftly, preventing disruption in business operations. A portal summarizing system metrics alongside alert capabilities would greatly enhance our operational efficiency.

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

"You can build your own cloud and make it customizable with APIs."

"My company could implement a lot of customizations and integration with load balancers and DNS. When we started using CloudStack, we didn't have that integration, so we developed that. We could fix anything missing in the solution."

"Everything in CloudStack works effectively."

"The most valuable feature from my point of view is access to environment via console through separate browser window."

"Over the years, we have valued CloudStack for its stability."

"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."

"CloudStack helped us showcase our features through process visualization and functional solutions."

"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."

More CloudStack pros

"The most valuable feature is the backup capability."

"This solution is working for both VTL and tape."

"Easy to operate and use."

"The best features of IBM Spectrum Computing are common across many of their storage products."

"Spectrum Computing's best features are its speed, robustness, and data processing and analysis."

"The most valuable aspect of the product is the policy driving resource management, to optimize the computing across data centers."

"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."

"We are satisfied with the technical support, we have no issues."

More IBM Spectrum Computing pros

Cons

"The product could improve by embracing newer technologies like GPU virtualization."

"A technology upgrade is one item which could be improved upon a lot."

"VPN P2S is cutting all connections except the CloudStack environment for the user when he is connected. I would like to have VPN like Cisco's AnyConnect."

"Lack of support for third-party software vendors such as Veeam and Zerto creates limitations on comprehensive offerings which would include backup and disaster recovery."

"The area of improvement could be the regionalization aspect. For example, managing multiple regions or HubStack deployments together was not thought out thoroughly in the versions I used. We faced issues around managing the global infrastructure and had to develop around it."

"It is not widely used so Google does not help very much when you are troubleshooting, and the CloudStack forum is not very active."

"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."

"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."

More CloudStack cons

"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."

"Lack of sufficient documentation, particularly in Spanish."

"IBM's sales and support structure can be challenging."

"The deduplication software isn't quite up to speed with the market. While IBM has excellent compression technology, specifically on their FlashCore modules, they lag behind competitors such as NetApp in deduplication capabilities."

"We'd like to see some AI model training for machine learning."

"This solution is no longer managing tapes correctly."

"The deduplication software isn't quite up to speed with the market."

More IBM Spectrum Computing cons

Pricing and Cost Advice

"CloudStack is an open-source product."

"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."

"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."

"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."

"The solution is open-source and free."

"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."

"This solution is expensive."

"Spectrum Computing is one of the most expensive products on the market."
