Using packstack: OpenStack deployment consists of a public network and a private network on one machine, hosting one CirrOS-image instance, with an attached storage volume. Installed OpenStack services include:
(运行knife工具对Chef进行配置) 可以有多个Client(运行chef-server的被配置机器) OpenStack的升级 Grenade /nebula/grenade Basic Process Install base OpenStack using current stable/base-release DevStack Perform basic testing (exercise.sh) Create some artifacts in a new project (javelin) for comparison ...
The OpenStack compute module also known as Nova is used to provision and manage the virtual machines. Nova is deployed into a private cloud using a number of hypervisors, KVM is one of the recommended choices for hypervisor technology. KVM was also VIAVI first choice of hypervisor for ...
OpenStack Compute serves as the core of the OpenStack cloud by providing virtual machines on demand. Compute schedules virtual machines to run on a set of nodes by defining drivers that interact with underlying virtualization mechanisms, and by exposing the functionality to the other OpenStack compo...
the comparison to SQL/NoSQL a Document in Elastic is a row in table in the case of SQL or a document in a collection in the case of NoSQL. As in NoSQL a Documentis a JSON object which holds data on a unit in your app. What is this unitdepends on the your app. If your...
A comprehensive performance analysis of various VM placement algorithms is conducted by Z. Mann and M. Szabo (2017) [23]. For overload and underload detection, the authors reuse algorithms from OpenStack Neat framework. The VM placement algorithms considered for comparison include PABFD and PAWFD...

One of the objectives of dynamic VM consolidation is the minimization of energy consumption by the physical nodes, which can be a metric for performance evaluation and comparison. However, energy consumption is highly dependent on the particular model and configuration of the underlying hardware, ...
described above, there are many outside of our defined "OpenStack umbrella", notablyCrowbar, the first OpenStack specific deployment tool. The only challenge now is to select a tool of your liking from a bunch of apparently good ones. An excellent in depth comparison of the tools is ...
By comparison, a PKI token is large in size. It exceeds even the HTTP header size. In an implementation for Symantec private cloud, for instance, PKI token size was 18KB. For what PKI tokens lack in brevity, they make up for in efficiency. Keystone middleware can decode a PKI token and...
