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.

Infrastructure Technical Specialist II at Clicks Group

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

"The API with CloudStack made integration into various external facing web applications simple enough."

"You can manage infrastructure with a few people, since product is monolithic."

"CloudStack is simple to stand up and get off the ground in a hurry. Its centralized design allows for easier troubleshooting when compared to OpenStack. Out of the box, it’s very well suited for white labeling and IaaS."

"We acquired some good clients for our billing and control portal solutions with CloudStack and it improved our business greatly."

"CloudStack is a very feature-rich product; it gives you a lot of control over your VM networks and has extensive integration with storage plugins where you can use many open source tools to bring storage into your CloudStack environment for backups or even to run VMs."

"We increased our IaaS sales by 30% and our deploy time of VM/instances has been reduced from one day to one minute."

"It was easy to deploy, both for PoC and production (with HA)."

"Key features include stability, centralized management design that scales well, and transparent interoperability with different hypervisors and manufacturers.."

More CloudStack pros

"IBM's ability to cluster compute resources is impressive, with built-in support for scenarios like VR and active-active configurations,"

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

More IBM Spectrum Computing pros

Cons

"The installation of CloudStack can be quite challenging because you need a good understanding of the product before starting."

"The web UI can be improved. It is too complex, and not trivial for the average user."

"The numerous, multi-layered drill-down menus make it difficult to find one simple knob to turn."

"The zones need to be more stable. During moving and first deployment there were a lot of issues."

"It would be a good to have more specific error messages within administration processes (e.g. problem with creating new instance)."

"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."

"I encountered some stability issues. When I tried to remove high-capacity virtual machines it took a long time to update, and sometimes the VM status failed to update properly in the cloud database. This occurred multiple times, even though I had sufficient resources."

"CS has very descriptive logging, and every time I faced issues and asked for help, I didn’t get any reply from the community. Reason? Its quite obvious. CS runs on specific environments, unique to each case. So, unless it is a functional issue of CS, nobody can help you. All issues were resolved by myself going through logs. This is another reason why you need smart enough people to manage it. Engineers must have knowledge of hypervisors and understand how CS interacts with them."

More CloudStack cons

"We have not been able to use deduplication."

"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."

"SMB storage and HPC is not compatible and it should be supported by IBM Spectrum Computing."

"Spectrum Computing is lagging behind other products, most likely because it hasn't been shifted to the cloud."

"Lack of sufficient documentation, particularly in Spanish."

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

"We are not fully satisfied with this product at the moment because we are having issues with reliability."

More IBM Spectrum Computing cons

Pricing and Cost Advice

"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."

"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."

"CloudStack is an open-source product."

"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."

"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."

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

"This solution is expensive."
