Apache CloudStack vs OpenStack: What are the differences?


Apache CloudStack and OpenStack are both popular open-source cloud computing platforms that offer Infrastructure as a Service (IaaS) capabilities. However, there are key differences between the two platforms that set them apart. Let's explore these differences in more detail:

  1. Architecture: One of the primary differences between Apache CloudStack and OpenStack lies in their underlying architecture. Apache CloudStack follows a more centralized approach where it utilizes a single management server to control and manage all resources within the cloud infrastructure. On the other hand, OpenStack follows a more distributed architecture where different services run on separate nodes, contributing to a more scalable and fault-tolerant system.

  2. Hypervisor Support: Another significant difference between Apache CloudStack and OpenStack is the hypervisor support. Apache CloudStack offers support for a wide range of hypervisors, including VMware, XenServer, KVM, and Hyper-V, allowing users to choose the most suitable option for their needs. OpenStack, on the other hand, primarily focuses on supporting the KVM hypervisor, although it can also integrate with other hypervisors through specific drivers.

  3. Maturity and Popularity: When it comes to maturity and popularity, OpenStack generally has a more extensive and vibrant user community compared to Apache CloudStack. OpenStack enjoys the backing of several leading technology companies, resulting in a broader adoption and ecosystem. Apache CloudStack, while still widely used in many organizations, may have a smaller community in comparison.

  4. Ease of Deployment: Apache CloudStack is generally considered to be more straightforward to deploy compared to OpenStack. With its centralized architecture and simplified installation process, Apache CloudStack can offer faster deployment times for organizations looking for a quick setup. OpenStack, on the other hand, may require more planning and configuration due to its distributed nature, making it suitable for organizations with more extensive and complex infrastructure requirements.

  5. Documentation and Support: Apache CloudStack provides comprehensive documentation, including installation guides, user guides, and API references, making it relatively easy for users to find the resources they need. OpenStack also offers extensive documentation, but due to its more complex nature, finding relevant information or getting support may require more effort, particularly for less experienced users.

  6. Integration and Ecosystem: OpenStack has a vast ecosystem of third-party plugins and extensions, allowing users to integrate with a wide range of complementary tools and services. This extensive integration capability makes OpenStack a highly flexible and customizable platform. While Apache CloudStack also supports integration with additional modules, its ecosystem may be more limited in comparison, potentially offering fewer options for customizations and specialized use cases.

In summary, Apache CloudStack and OpenStack differ in their architecture, hypervisor support, maturity, ease of deployment, documentation and support, as well as integration capabilities. Organizations should consider their specific infrastructure needs and requirements when choosing between these two cloud computing platforms.

What is Apache CloudStack?

CloudStack is open source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform.

What is OpenStack?

OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources throughout a datacenter, all managed through a dashboard that gives administrators control while empowering their users to provision resources through a web interface.

What are some alternatives to Apache CloudStack and OpenStack?
Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.
It provides a simple but feature-rich and flexible solution for the comprehensive management of virtualized data centers to enable on-premise enterprise clouds in existing infrastructures. It can be primarily used as a virtualization tool to manage your virtual infrastructure in the data-center or cluster, which is usually referred as Private Cloud. It supports Hybrid Cloud to combine local infrastructure with public cloud-based infrastructure, enabling highly scalable hosting environments.
JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
GitHub is the best place to share code with friends, co-workers, classmates, and complete strangers. Over three million people use GitHub to build amazing things together.
