Swift, Glance, Cinder - The three storage-related components under OpenStack are just as familiar as the components themselves appear: Swift - conceptually similar to an Amazon S3 service, Object Storage (Object Storage), but swift has strong scalability, redundancy and durability, but also compatible with S3 API Glance - including a lot with Amazon AMI catalo ...

Domestic free virtualization OVM Compared with OpenStack, OpenStack as a global open source software, its design was first positioned for large and medium-sized enterprises, because these enterprises can send a rich and powerful technical team for in-depth development and maintenance, and For lack of software development and operation and maintenance capabilities of traditional enterprises and SMEs, Yi Siwei OVM is 100% better choice. OVM is a one-stop solution out of the box OpenStack open source software installation and deployment for many operation and maintenance personnel are no stranger to, most enterprises only provide installation package ...

As companies begin to leverage cloud computing and large data technologies, they should now consider how to use these tools in conjunction. In this case, the enterprise will achieve the best analytical processing capabilities, while leveraging the private cloud's fast elasticity (rapid elasticity) and single lease features. 　　How to collaborate utility and implement deployment is the problem that this article hopes to solve. Some basic knowledge first is OpenStack. As the most popular open source cloud version, it includes controllers, computing (Nova), Storage (Swift), message team ...

Two years ago OpenStack based on the NASA Nova project and the Rackspace Swift Project merger, OpenStack has become a new star in the Cloud computing field, following the release of the Essex version in April 2012, At the end of September this year OpenStack 6th edition Folsom officially released, this article briefly analyzes the OpenStack Folsom architecture. Folsom Logical structure diagram Object Store Swift structure is distributed so that you can ...

OpenStack actually has three storage-related components, and these three components are well known to coincide with the timing of the component itself, arranged as follows: swift--provides object storage, which is conceptually similar to Amazon S3 Services, However, Swift is highly scalable, redundant, and persistent, and also compatible with the S3 API glance--provides virtual machine mirroring (image) storage and management, including many with Amazon AMI catalog ...
