"5 minutes a day with OpenStack" is an OpenStack tutorial, this is the 1th article.This tutorial has the following two features: The system explains OpenStackFrom the architecture to the individual components, from the whole to the detailed discussion re-practice and take into account theoryMainly from the actual operation of the point of view with everyone learning

balance between. More discussion of system performance and architecture is also being carried out around consistency and availability.2) engineering practices for OpenStack, Swift and CapIn contrast to cap theory, OpenStack's distributed object storage System, swift, satisfies availability and partition tolerance, without guaranteeing consistency (optional), but achieving eventual consistency. Swift if the get operation does not include the ' x-newes

Network Services OverviewOpenStack Networking (neutron), which allows you to create and plug in interface devices that are managed by other OpenStack services. Plug-in implementations can accommodate different network devices and software, providing flexibility for OpenStack architecture and deployment.It contains the following components: Neutron-server:The receive and route API requests to

access. The above is a few steps to create the core of the virtual machine, of course, also omitted a lot of details, we will discuss in detail in later chapters. These steps show us the way the collaboration between the nova-* sub-services is, and the distributed design of the entire OpenStack system, which is very helpful for us to gain an in-depth understanding of OpenStack.In the next section we will

Because the lab needs to add a compute node to the OpenStack cluster, the process of adding compute nodes is recorded here. The cluster is still using the FLATDHCP network approach. The new node of the machine is still dual network card, here special attention, can not use an Ethernet card and a wireless card as a dual network card, because the wireless network card can not bridge to the bridge br100, or you will receive the following error: error:fai

When we deployed, we saw that it had 30 VLANs by default, which is VLAN ID 1000-1030. We know that OpenStack can have a lot of tenants, each tenant can have their own network, the n

Introduction to 1.openstackOpenStack was developed by NASA and Rackspace in collaboration with Apache Licensing and is a free software and open source project.OpenStack is a project managed by a cloud platform and it is not a software. The project consists of several major components that are combined to accomplish some specific work. OpenStack is an open source project designed to provide software for the building and management of public and private

At the OpenStack summit in Atlanta, RedHat confirmed several OpenStack-related projects. One of them is that RedHat is working with eNovance, the leader in the open-source cloud computing market. Both parties will promote network function virtualization and integrate telecom functions into OpenStack. Red Hat announced that it would invest in eNovance in cash and

After six months of Public Beta, unitedstack (Beijing) Technology Co., Ltd. (hereinafter referred to as unitedstack) has developed the openstack cloud service platform UOS 2.0 for commercial use recently. In the words of cheng hui, founder of unitedstack, UOS 2.0 is China's first cloud computing platform to officially provide operation services to external users based entirely on the openstack open standard
