The full text includes three parts: The first part Part II Part III In the first part of this series, I covered six requirements for enterprise-level OpenStack. Now, I'll focus on the next two main requirements: open architecture and hybrid cloud compatibility. Let's get started right away.Demand 3-open architecture and reduce vendor lock-inWe've talked about building robust cloud control planes and cloud management systems. One

Install openstack on devstack Devstack is a set of scripts for developers to quickly deploy the Openstack development environment. In fact, there is nothing to say about the entire installation process, because the script is well written, there are no major problems with brainless installation. However, due to the poor network environment in the company, I still encountered many problems during the installa

Keystone Project provides user management, rights Management, user authentication and other functions, but also provides Servicecatalog, which is the endpoint of all services in OpenStack. Endpoint is the base URL for the rest API. Keystone is the portal for OpenStack, and calling the OpenStack Rest API starts with Keystone. Rest API Flow1) Call Keystone Tokens

Even Microsoft Exchange began recommending the evolution from RAID to JBOD, which instead relied on the application layer for fault tolerance.Let's take a closer look at the three requirements of enterprise-class OpenStack.Scalability and Performance (Scalability performance)Scalability is a feature of the system's ability to meet growing system size and load requirements.

RedHat plans to launch enterprise-level open source OpenStack software to host IaaS (Infrastructure as a service) deployment. The company has released an unsupported preview version, and the complete commercial version is expected to be released in early 2013.

CEO of RedHat on VMware, OpenStack, and CentOS RedHat has completed an acquisition to build an open-source stack that leads the hybrid data center, and its main competitor is VMware. The duel between RedHat and VMware remains to be observed, but Jim whitehust, CEO of RedHat, believes that open source will ultimately define the future of enterprise IT architecture. I met whitehirst and talked to him about the overall planning of cloud, open source, and

Preface: The entire openstack consists of control nodes, computing nodes, network nodes, and storage nodes. The basic management services of control nodes include five services: Keystone, glance, Nova, neutron, and horizon.
