AboutSource codeOnly the XMPP server is used to implement openfire and swift. Think about the stagnation of swift learning during this period, and feel that "if you want to learn the principle of something, you must first use it ", this will increase the understanding of the function processing process to a certain extent and resonate with the source code reading. For Swift API learning, because you have not found any reference system, there is no link on the official document homepage, theref

Original article:Http://www.yeeyan.com/articles/view/pestwave/26832 Rackspace recently released a survey on cloud hosting. The company visited 1500 British and U.S. small and medium-sized companies and asked if they knew what cloud hosting was and whether they planned to use cloud hosting in the future. The results are surprising. The most important finding is that there is a big gap between small and medium-sized enterprises in their acceptance of c

Background and overviewSwift was originally a highly available distributed object Storage service developed by Rackspace, and in 2010 contributed to the OpenStack open source community as one of its initial core sub-projects, providing virtual machine image storage services for its Nova subproject. Swift is built on a less expensive standard hardware storage infrastructure, eliminating the need for RAID (redundant array of disks), enabling high availa

: Ubuntu Server.Like Rhel and SLEs, Ubuntu also offers technical support and product certifications, but its resource reserves are not as rich as Red Hat and SuSE. On the other hand, however, Ubuntu is easier to manage when performing simple server tasks. Linux server systems best suited to expert users Arch Gentoo Debian Fedora If you have a deep interest in cloud computing, don't forget that Ubuntu (as well as Rhel) can connect with OpenStack in depth.

, tracking, reporting, and so on. Patching systems are similar to fire extinguishing, where users should isolate worms or viruses on the network segment before initiating the patching process. Rackspace's CTO, Mr. Engates, believes that patching routers and firewalls are very similar to the version of the upgrade software. The company is staffed by a network engineer to track vulnerabilities in firewalls and routers. After a patch is identified, the engineer notifies the IT director that if the

Openstack compute (NOVA) Function Analysis Openstack compute provides a cloud tool for an organization. Its functions include running Virtual Machine instances,Manage networks and control cloud access through users and projects. The most basic open-source project of openstack is named Nova. It provides software that can control the infrastructure as a service (IAAS) cloud computing platform, and AmazonEC2 and rackspace ECs are similar

computing and Big Data System Research Group of the institute of software, Chinese Emy of sciences, gave a speech entitled "Open Source Distributed Object Storage Service (openstack SWIFT )". Openstack Object Storage (SWIFT) is one of the sub-projects of openstack's open-source cloud computing project. Swift uses common servers to build reliable and Scalable Distributed Object Storage clusters with a storage capacity of hundreds of petabytes or even exabytes. Swift, formerly known as the

Two main modules: Nova and Swift. The former is the virtual server deployment and business computing module developed by NASA, and the latter is the distributed cloud storage module developed by Rackspack, which can be used together, it can also be used separately. OpenStack is an open-source project. In addition to the strong support of Rackspace and NASA, there are also contributions and support from heavyweight companies such as Dell, Citrix, Cisco

computing power.2. What does IaaS mean?Iaas:infrastructure-as-a-service (infrastructure as a service)The first layer is called IaaS, sometimes called Hardware-as-a-service.A few years ago if you want to run some business applications in your office or on your company's website, you need to buy servers or other high-level hardware to control your local applications and get your business up and running.But now with IaaS, you can outsource your hardware to other places. IaaS will provide off-site

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
