1 Introduction 1.1 About Mirantis Mirantis, a great OpenStack service integrator, is the only one of the top 5 community contributors to eat on software and services (others are red Hat, HP, IBM, Rackspace). Compared to several other community distributions, the fuel version is fast-paced and provides a relatively stable community version every two months. What's 1.2Fuel? Fuel is a tool designed for OpenStack End-to-end "one-click Deployment" that

Commercial cloud storage services, such as Amazon S3 and Google Cloud Storage, offer highly available, scalable, and unlimited volume object storage services at affordable prices. To speed up the widespread adoption of these cloud products, these providers have developed a good developer ecosystem for their products through explicit APIs and SDKs. The cloud-based file system is a typical product in these active developer communities and has several open source implementations. S3QL is one of th

OpenStack supports almost all types of cloud environments, and the project aims to provide a simple, scalable, ri

, performance, and security may change as new quality requirements are raised. These quality attributes are often not solved by old technology. Rackspace's case for log processing falls into this scenario [2]. Rackspace of the architecture of the log support, has undergone three major versions of the evolution, from the file server to the central database, and then to MapReduce, each technology stack migration is a quality attribute of the drive, have

Therefore, the server provider's Web site to ensure that people can easily identify the nature of the site and faster access to host information. After all, people on the host site will not often stay in time. This article collects the foreign host website itself to be very beautiful, at the same time in th

"We also need to build our own system," Aric Zeniek Arik Czerniak, co-founder and CEO of Metacafe, the third-largest Internet ranking company, said recently. "ComScore networks data show that last September Metacafe had 16.6 million independent user visits and 492 million pages of readings worldwide. "To this scale, it's a huge technical challenge to make sure the site runs smoothly," Zeniek. ” Iya

-DDoS attack solution used in this test was Cisco's acquisition and integration of products called Riverhead, which made a very important innovation in dealing with DDoS, and presented the concept of "guidance" and the two key defenses against DDoS attacks: anti-deception defense lines and statistical analysis lines. The system is composed of intelligent DDoS protection system detector detector and protective device guard. In foreign telecom operators, portals, online gaming companies and onlin

Background and overview Swift 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 subprojects, providing virtual machine mirroring storage services for its Nova subprojects. Swift builds on a relatively inexpensive standard hardware storage infrastructure, eliminates the need for RAID (redundant array of disks) to achieve

2009, Last.fm's Johan Oskarsson launched a discussion on the distributed open source database, and Eric Evans from Rackspace again proposed the concept of NoSQL, when NoSQL mainly refers to non-relational, distributed, does not provide an acid database design pattern.The No:sql (East) symposium, held in Atlanta in 2009, was a milestone with the slogan "Select Fun, Profit from Real_world where Relational=false;". Thus, the most common explanation for

Indexes they offer strong support but perform poorly on rotating disks (which is still the most cost-effective since many) require reading or writing what work. An interesting variant is the addition of COUCHDB, only B-tree, which avoids the purpose of managing expenses in limiting Couchdb to write one-time costs. Conclusion The NoSQL campaign has exploded over the past 2009 years as more and more companies are grappling wit

By 2027, the global real private cloud (true private CLOUD,TPC) market will reach $262.4 billion, with an annual CAGR of 29.2%, while the TPC market will grow faster than the public cloud IaaS market, while the locally deployed TPC market will be 32.5% Growth of $176 billion. This is the latest forecast by Wikibon, a U.S. market research firm, released in August 2018. In 2017, the global TPC market grew by 55% to $20.3 billion, while the TPC market was 40% of public cloud IaaS and grew at a rate
