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.

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.

The market keeps changing, and so does technology. I think that container technology in CloudStack is an area that needs to be improved. Regarding container technology, Kubernetes is something many people want to use and something which, as of now, many are using currently. However, there is still room for improvement in Kubernetes, particularly with networking functionality and network virtualization. When it comes to what needs to be improved in CloudStack, I would say that it should stay the way it is currently. It should continue being a stable product that people can rely on since many may be inclined to follow the latest trends and hype, which is not always good for a solution's stability. It is crucial to prioritize stability, which is a key factor that companies seek. In my view, the platform could benefit from adding more metrics. More metrics would offer more insights and data on the platform's performance, utilization, and usage. Overall, I believe that having more metrics available would be highly desirable.

Valuable Features

CloudStack offers ease of use, extensive hypervisor compatibility, scalability, and robust API support. Users appreciate its advanced networking, including isolated/shared networks, NAT, VPNs, and VPCs. It's efficient for virtualization and cloud orchestration, integrating well with Kubernetes. The centralized design simplifies management and troubleshooting, and customizable features enhance user experience. With multi-zone capabilities, flexible integrations, and effective workload management, CloudStack stands out as a versatile, stable infrastructure platform widely preferred over alternatives.

"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."
"CloudStack provides an environment that is very simple to use, with built-in APIs and a web interface that supports almost all features of AWS and Azure."
"Everything in CloudStack works effectively."

Room for Improvement

CloudStack requires enhancements in upgrade processes, user interface simplicity, and integration with third-party products. Areas like virtual router functionality, stability during network disruptions, and error feedback can be refined. Users seek better support for backup, disaster recovery, and more comprehensive documentation. There's demand for improved container technology, billing solutions, and hypervisor integration. Users note limitations in regional management and network monitoring tools. Feedback emphasizes more active community participation and promotion for commercial adoption.

"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."
"CloudStack lacks a billing solution which would complete it as a full 360-degree product."
"The product could improve by embracing newer technologies like GPU virtualization."

Pricing

CloudStack is an open-source solution with no inherent licensing costs under the Apache license. While the software itself is free, enterprises might incur expenses for professional technical support, training, or consulting services. Infrastructure and hosting fees are separate. Commercial support options are regarded as cost-effective, providing fair pricing for quality services. Additional costs may arise when using commercial hypervisors like VMware, or when specific features require separate licensing fees.

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

Popular Use Cases

CloudStack is used by entities to offer infrastructure as a service, streamlining both public and private cloud deployments across varied environments. Users implement it for centralized management of virtual machines, orchestration, and automation in data centers. Companies benefit from its open-source framework to create user-friendly portals, handle billing, and integrate with LDAP. CloudStack supports diverse use cases such as private cloud setups, virtual environments, and hybrid cloud services across multiple global locations.

Service and Support

CloudStack's assistance involves an active community offering timely interactions, although responses can depend on issue specifics. Several entities like ShapeBlue provide extra assistance, while some rely on internal skills. Commercial options vary in effectiveness, with some preferring community forums and industry expertise for resolving concerns.
