OpenStack is described as 'Global collaboration of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for public and private clouds. The project aims to deliver solutions for all types of clouds by being simple to implement' and is a popular Cloud Computing service in the business & commerce category. There are more than 50 alternatives to OpenStack for a variety of platforms, including Web-based, Linux, Self-Hosted, Windows and SaaS apps. The best OpenStack alternative is QEMU, which is both free and Open Source. Other great apps like OpenStack are Proxmox Virtual Environment, Microsoft Azure, Linode and Amazon Elastic Compute Cloud.
QEMU, an open-source hypervisor, performs hardware virtualization, emulates CPUs using dynamic binary translation, and supports various architectures. It runs diverse unmodified guest OS, provides device models, and offers mixed translation modes for efficient execution.
Proxmox Virtual Environment is a complete and easy to use Open Source virtualization platform for running Virtual Appliances and Virtual Machines. Proxmox VE tightly integrates KVM hypervisor and LXC containers, software-defined storage and networking functionality on a single...
The Azure cloud platform is more than 200 products and cloud services designed to help you bring new solutions to life—to solve today’s challenges and create the future. Build, run, and manage applications across multiple clouds, on-premises, and at the edge, with the tools and...
Linode’s cloud computing platform was launched in 2003, to accelerate innovation by making Linux virtual machines simple, affordable, and accessible to all. Since then, 100,000’s of developers and businesses around the world have deployed and scaled their modern applications...
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.
This service provides over 200 scalable cloud offerings including networking, computing, storage, and IoT, accessible via global server farms. It features a pay-as-you-go model with autoscaling, extensive global infrastructure, and robust security tools, suitable for enterprises.
Apache's CloudStack is a Project backed by Citrix and designed to be a direct competitor to OpenStack. It is designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform.
Google App Engine is a free* platform for developing and hosting web applications in Google-managed data centers. App Engine offers fast development and deployment; simple administration, with no need to worry about hardware, patches or backups; and effortless scalability.
VMware vSphere Hypervisor ( based on ESXi ) is a free bare-metal hypervisor that virtualizes servers so you can consolidate your applications on less hardware.
SmartOS is a hypervisor lean enough to run entirely in memory, powerful enough to run as much as you want to throw at it. Provisioning is blindingly fast, thanks to zones and ZFS file system creation.
Xen.org, home of the Xen hypervisor, the powerful open source industry standard for virtualization. It is a native (bare-metal) hypervisor providing services that allow multiple computer operating systems to execute on the same computer hardware concurrently.
Google Cloud platform enables you to build and host web apps on the same systems that power Google applications. App Engine offers fast development and deployment; simple administration, with no need to worry about the underlying infrastructure and systems, patches or backups...
