OpenStack project, started two years ago by NASA and Rackspace, aims to create an open source software stack to provide IaaS cloud services. As a modular software stack, OpenStack includes independent programs to support computing, Object Storage, image management, and other services required to run cloud operations. The project was quickly popularized, attracting more than 3300 programmers and 185 plus companies to participate in the development pro

The availability of dashboard has been good, but Tumblelog has not been good enough because the infrastructure is old and difficult to migrate. Owing to the shortage of manpower, womb.

should immediately start testing the patch. If the user lacks funds to establish an experimental environment, the user should at least try to simulate the environment of key business systems. After testing the patch program, you must complete patch distribution, deployment, exception handling, tracking, reporting, and other work. The repair system is similar to fire suppression. If necessary, the user should isolate the worm or virus from the network segment and then start the repair process. M

1. Keep in mind the basics Don't forget every basic step in the migration process. Although the migration process has to stop, but when the original server is still in, to do as much as possible, as frequently as possible load test. Also, remember to modify domain DNS and, in general, set the TTL as low as possible. It is a good practice to do a test that 3~4 times the new DNS run plan before migrating. 2. Know your App Based on past experience, you need to understand the architecture of your

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

. Later, Director Mo discussed in detail the features of Block Storage and Object Storage. Block Storage is applicable to databases, index systems, random access, and other data files. Object Storage is applicable to unstructured data such as images and video archives. Gong Yu, head of the cloud 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

PhpFastCache PhpFastCache is an open-source PHP Cache library that provides only one simple PHP file and can be easily integrated into existing projects. it supports multiple caching methods, including apc, memcache, memcached, and wincache, files, pdo and mpdo. You can use a simple API to define the cache validity period.3. Eden: powerful PHP library Eden is an open-source and free PHP quick development class

Some companies provide commercial storage services based on SWIFT, including kt, rackspace (the birthplace of SWIFT), and internap. Many large companies also use swift to store their internal data.

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.

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
