openstack tools

New features and functions of openstack grizzly Nearly 230 new features involved computing, storage, network, and sharing services. Openstack computing virtualization-computing uses "cells" to manage distributed clusters, and uses the "nodb" Host Architecture to reduce dependency on central databases. Virtualization management also provides new features and manages various virtual machines.ProgramAll pr

The core of OpenStack: The core is computing, networking, and storage, and everything revolves around the virtual machine as the main body. OpenStack Modules: Nova: Managing the lifecycle of a VM is the core service of OpenStack. Neutron: Responsible for creating L2, L3 networks, providing virtual network and physical network connectivity to VMS, is the most dif

Security groups in OpenStack implement communication between trusted virtual machines, and the same security policy is used for virtual machines that bind to the same security group. The security group is scoped to the virtual machine and more specifically to the port on the virtual machine than to the network. The security group in OpenStack is based on iptables implementation, and because the current open

The official website www.openstack.org the most popular community, sponsored by Rackspace and NASA's Open source cloud computing community, the major IT giants involved in the program, the domestic Sina's SAE contributed a lot. OpenStack is known as the 21st Century Linux open source community, can foresee its development prospects is how vast. OpenStack's core project was increased from the previous two to the following: Cloud Compute (Nova) project

Catalogue The catalog Keystone certification process allows Keystone to provide validation capabilities for a new project Service finally Keystone Certification Process User uses credentials (Username/password) to Keystone authentication and obtains a temporary token and Generic catalog (global catalog), and temporary tokens are stored in the keystone-client (cache UUID locally) and Keystone-backend. User uses this temporary Token to send to Keystone and obtains a tenants list that the user can

Test classification in OpenStack Test categories in OpenStack can be divided into the following types:1) unit test (small test/unit tests) Unit tests are stored in the code library of each component. For example, unit tests of nova are stored in the nova/tests directory. Unit Tests are mainly aimed at testing the source code and testing the code at the function level. Need data or a simulated environmen

OpenStack is a cloud operating system that controls a large pool of computing, storage, and network resources in the entire data center. All resources are managed through a dashboard, which gives administrators control and allows users to prepare resources through the Web interface. OpenStack is a cloud operating system that controls a large pool of computing, storage, and network resources in the entire da

Mirantis, one of the benchmark companies in the OpenStack field, released the latest MOS 8.0 version in early March 2016. This paper tries to make some inductive analysis based on the public data.1.

Chinese garbled characters in OpenStack Databases The SQL connection of openstack must be configured with UTF-8 to avoid Chinese garbled characters. SQL _connection = mysql: // nova: xxx @ qa-mysql1: 3306/nova? Charset = 'utf-8' However, if UTF-8 is not set before, the database cannot be cleared at will. to update a field in the openstack database, you cannot dir

In May this year, HP announced the Helion cloud plan and plans to invest $1 billion in the next two years. Next, HP began to methodically promote the implementation of the plan. The latest news is that in July 1, Hewlett-Packard announced the establishment of a Global Helion alliance, hoping to attract independent software vendors, developers, system integrators, and value-added dealers to join in and build an openstack-based cloud ecosystem, helps cu

To get a better understanding, let's start with the type of cloud computing. Depending on the type of service provided, cloud computing has the following three landing methods:1. Iaas (infrastructure as a service) from which users can request hardware or virtual hardware, including bare metal or virtual machines, and then install the operating system or other applications on top.2, PaaS (Platform-as-a-service), the user can apply to a installation of the operating system and support the applicat
