What is Apache CloudStack? Apache 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. CloudStack is used by a number of service providers to offer public cloud services, and by many companies to provide an on-premises (private) cloud offering, or as part of a hybrid cloud solution. CloudStack is a turnkey solution that includes the entire "stack" of features most organizations want with an IaaS cloud: compute orchestration, Network-as-a-Service, user and account management, a full and open native API, resource accounting, and a first-class User Interface (UI). CloudStack currently supports the most popular hypervisors: VMware, KVM, XenServer and Xen Cloud Platform (XCP) and Hyper-V. Users can manage their cloud with an easy to use Web interface, command line tools, and/or a full-featured RESTful API. In addition, CloudStack provides an API that's compatible with AWS EC2 and S3 for organizations that wish to deploy hybrid clouds. Join the CloudStack Silicon Valley User Group Anyone is welcome! We will have talks from members of the foundation, committers, and users of CloudStack discussing various aspects of its development, history, architecture, operation and in general the direction of the project in this and upcoming meetups. And most importantly - how to get started on contributing yourself! Anyone is welcome to the group and we'll have beginner sessions available as well.
