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.

Pros

"Cloud computing has improved the way our organization functions."

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

"It is very easy to install and manage. It has the all modules in one node, unlike other software (OpenStack). The product allows a customized look and feel, and the ability to add custom workflows."

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

"The APIs for automation in CloudStack are excellent; everything is API-driven, and while the API is very rich and hard to learn, you can do everything you would want to do, including everything in the user interface and more."

"We chose CloudStack because we saw it with a better TCO ratio, balancing innovation, and starting the DevOps culture with a low operational overhead."

"Valuable features include that it is a user-friendly portal, VPN P2S and S2S possibilities, and it's easy to manage accounts and limits."

"CloudStack is highly stable."

More CloudStack pros

"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 worked as expected and it is reliable."

"The most valuable feature is the backup capability."

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

More IBM Spectrum Computing pros

Cons

"Factors that need improvement are: Visualization in terms of the resources usage. The user interface. Providing best error feedback to the users."

"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."

"The upgrade process can be improved further."

"The area of Apache CloudStack that could stand the most improvement is the functionality/features around the virtual routers. They can be somewhat cumbersome to deal with at times and are the least stable piece of the product."

"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."

"The absence of the feature, deploy an instance from a snapshot, is the weak point of the platform. It is a feature that everyone needs nowadays."

"More integration with third-party products (we know that OpenStack has a better level of integration)."

"Companies need to be knowledgeable about cloud technology. It's not for novice users."

More CloudStack cons

"In Pakistan, IBM's disadvantage is the lack of OEM support and presence."

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

"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."

"This solution is no longer managing tapes correctly."

"Lack of sufficient documentation, particularly in Spanish."

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

"Software sometimes is a little slower. It takes two or three days sometimes."

More IBM Spectrum Computing cons

Pricing and Cost Advice

"It is a 100% open-source solution needing just an Apache license. Also, there are no hidden fees to be paid."

"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."

"There is no license, so the product is free unless you are buying professional technical support services."

"The solution is open-source and free."

"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."

"Give an effort to planning. If possible, contract a specialized consultant company for the initial setup and knowledge transfer."

"This solution is expensive."

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