Valuable Features

CloudStack offers valuable features such as easy installation, multi-hypervisor support, advanced networking, and strong API integration. It is favored for its scalability, user-friendly interface, centralized design, and efficient management. Users appreciate its stability, customizability, and effective VM migration. It supports complex virtual environments, advanced network functions, and multiple VPN setups. Integration with storage solutions and flexibility in configuration enhance its appeal, allowing seamless adaptation to diverse requirements.
  • "It was easy to deploy, both for PoC and production (with HA)."
  • "CloudStack is highly stable."
  • "I can recommend CloudStack because there are a lot of large companies using it in production for critical mission systems, and everything else."

Room for Improvement

CloudStack requires improvements in its UI, making it more intuitive for all users. Automation in management server upgrades and better error feedback is needed. It lacks consistent integration with third-party tools such as Veeam and Zerto. Enhancing stability, expanding GPU functionality, and adding billing options would enhance its capabilities. More active participation in its open-source community and better promotion could also address current limitations.
  • "The user can't upload SSH keys from the UI. We have to use the API for this, and it is not always convenient."
  • "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."
  • "However, I believe that CloudStack needs to grow their marketing in the commercial side. They don't have a great piece of market share right now."

Pricing

CloudStack, being an open-source product under the Apache license, is free with no licensing costs. Enterprise buyers should consider expenses for dedicated support, training, or initial setup, often handled by specialized consultants. Additional costs include infrastructure, hosting, and hypervisor fees, particularly for features like XenMotion. Support and service options, while extra, are noted for being fair and cost-effective.
  • "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 primarily used for deploying and managing IaaS across diverse environments including private, public, and hybrid clouds. Companies utilize it for virtual machine orchestration, resource management, and to offer tailored cloud services. The platform supports integration with different hypervisors and hardware, facilitating user-friendly portals for VM creation and management. Organizations also leverage CloudStack for infrastructure support, centralization of services, test environments, and cloud orchestration, catering to customers' varied requirements.

Service and Support

CloudStack's support heavily relies on its active community, providing helpful forums and quick responses. Some organizations receive assistance from companies like ShapeBlue, while others manage internally with technical expertise. Commercial support has been criticized post-Citrix divestiture, but community forums typically offer the needed aid. Although no dedicated team exists, certain companies offer professional help with paid services. Community members often rate support highly, citing ease of problem-solving through collaborative efforts.

Deployment

Users found CloudStack's initial setup generally simple and straightforward, especially with its monolithic architecture. Installation guidance facilitated ease of use, although some encountered complexities related to networking and hypervisors. Challenges varied depending on expertise and environmental readiness. Experienced users emphasized documentation's importance. While considered simpler than competitors like OpenStack due to fewer components, maintaining the system requires skilled personnel. Some managed successful deployments quickly, while others faced challenges with scalability and environment-specific configurations.

Scalability

CloudStack demonstrates strong scalability, managing thousands of hosts without issues. It offers powerful scaling options like availability zones and clusters, accommodating small to large businesses. Users can easily add servers, though some research and testing are recommended before making changes. While documentation could improve, CloudStack efficiently scales infrastructure with minimal complexity. Its capacity for growth is widely acknowledged, supporting various environments seamlessly, even with integration needs. Some limitations arise from user infrastructure, not CloudStack itself.

Stability

CloudStack is generally stable, though some encountered occasional challenges with stability, such as issues related to secondary storage and management service interruptions. Newer versions often improve stability, and community support helps address bugs. Some experienced stalls in virtual machine updates and network-related issues. Regular updates are needed, and while support is limited due to a smaller community, professional services can assist. Users rate stability highly, citing its capability to operate steadily and improve over time.

CloudStack Reviews Summary
Author infoRatingReview Summary
Senior Infrastructure Consultant at Infosys4.5I've used CloudStack for over two years to manage large cloud infrastructures, finding it reliable, scalable, and easy to use, though I'd like to see better built-in alerting features to enhance our operational efficiency.
Executive Director (IT and ERP) at Ha-Meem Group4.5CloudStack is essential for our development environment, providing an easy-to-use platform with built-in APIs, scalable deployment, and compatibility with AWS and Azure features. However, it lacks a billing solution and could benefit from improved documentation and additional user interface enhancements.
System specialist at Savecore3.5We've used CloudStack for two years to deliver flexible virtual cloud services; it's powerful and scalable with strong API support, though its setup is complex and the user interface could be simpler for end users.
Cloud Architect at a tech services company with 11-50 employees4.5I've found CloudStack to be a stable, scalable, and feature-rich cloud platform that's easy to deploy, supports multiple hypervisors, and integrates well with automation tools, though there's room to improve container support and complex VM migrations.
CTO at a computer software company with 11-50 employees4.5We use CloudStack for both private and public cloud setups, finding it effective for compute, disk, virtual networking, and Kubernetes services. While OpenStack is a competitor, CloudStack is easier to manage. Improvements could include embracing GPU virtualization.
CTO at Encha3.0I found the initial implementation of CloudStack satisfactory, but faced limitations like the lack of an easily implementable payment gateway, prompting me to create my own stack. Previously, I switched from Rackspace/OpenStack due to dependency issues, and evaluated but rejected Microsoft's proprietary control.
Engineer Manager at Globo.com4.0I've used CloudStack for seven years. It's stable, scalable, and highly customizable, allowing our own integrations. However, upgrades are painful due to code merging, and cost management is missing. Initial setup was complex.
Community Ambassador at 42on5.0As a shared hosting provider, we rely on CloudStack for its stability and open-source benefits. While it excels in virtualization, improvements in container and networking features are needed. Its Apache backing and our successful tests reaffirmed our choice.
