A simple interface and helpful support for a solution that grows with us

It's a flexible enough tool to submit the changes that you want. It gives you the ability to cancel any loop. You can connect new orchestrations together. It offers enough support so that you don't need to have the need to get another device. The user interface is simple and easy to use.

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.

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

Pros

"It offers enough support so that you don't need to have the need to get another device."

"I strongly recommend the solution to people."

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

"Everything in CloudStack works effectively."

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

"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."

"CloudStack has greatly helped integrate our existing infrastructure because we manage a massive cloud platform with thousands of VMs and around 1,200 to 1,500 hypervisors."

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

"It allowed us to build and manage a virtual environment much larger than we originally thought would be possible for our organization."

"CloudStack is our private IaaS cloud which helps us manage resource usage in our company and it is also a great PoC environment."

More CloudStack pros

Cons

"The solution is just too expensive, so maybe the pricing could be better."

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

"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."

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

"This product needs a lot improvement on the development side. Every new version introduces new bugs. It lacks many features needed for NFV like DPDK, SR-IOV support, etc."

"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."

"From time to time there is a bug in calculating limits of resources for customer domain/account. Maybe it’s a problem with 4.9.2."

"We did encounter issues with stability, and the main issue was secondary storage. When it is not available, XenServers and hypervisors are affected. And CS doesn’t do anything to reboot, or fix. Come to think of it, maybe it shouldn’t, considering their approach – CS just orchestrates everything else on the hypervisor and storage level."

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

Pricing and Cost Advice

Information not available

"The solution is open-source and free."

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

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

"The Apache CloudStack is open source, so you do not have licenses to purchase."

"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."

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

"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."
