Online Storage Solutions Review

The fastest way to store a computer system is the ram traditionally used primarily as memory. As the access performance of the hard drive has deteriorated over the years, and the cost of RAM has been decreasing, many researchers have been exploring how to replace the hard disk with memory in recent years. As early as the 1980, David DeWitt and Garcia-molina and so on published a main memory database paper. Steven Robbins's article points out that the Turing Prize winner, Jim Gray, is more explicit about the idea that "memory will be a hard drive and the hard drive will become a tape."

Today, as we focus on cloud computing, the storage sector also launches discussions on cloud storage. Cloud storage is an online storage mode that stores data in a virtualized storage pool provided by a third party. 　　By 2014, according to IDC, the cloud storage market would be more than $7 billion trillion a year, compared with about $1.5 billion in 2009. Cloud storage and cloud computing have the same characteristics in terms of agility, scalability, and multi-tenant, and the advantages of this model are obvious: they simply pay for the capacity they actually use, and the enterprise no longer relies on its own ...

The architectural challenges behind the tumblr:150 of billions of months of browsing are the same as many emerging websites, where the famous light blogging service Tumblr is facing the bottleneck of the system architecture in the rapid development. 500 million times a day, peak 40,000 requests per second, 3TB of new data storage, more than 1000 servers, in this case how to ensure the smooth operation of the old system, smooth transition to the new system, Tumblr is facing enormous challenges. Tumblr was very typical of lamp applications. is currently evolving to a distributed service model based on SCA ...

End-to-end encryption policies must take into account everything from input to output and storage. Encryption technology is divided into five categories: file-level or folder-level encryption, volume or partition encryption, media-level encryption, field-level encryption and communication content encryption. They can be defined further by the encryption key storage mechanism. Let's take a look at the grim forecast: According to the US Privacy information exchange, One-third of the U.S. people will encounter the loss or leakage of personally identifiable information from companies that store data electronically this year. Whether that number is not exactly right, anyway the public knows the data leaks ...

With the dual drive of information technology and application, the construction, management and operation of data center are constantly being adjusted and improved. Energy efficiency and intelligent management will lead the direction of data center technology and application change. 　　The further integration of it with the data center industry will open up new horizons for the development of the data center industry. April 10, sponsored by the China Computer newspaper, "2014 China Data Center Conference" in Beijing New Century Hotel held. The Annual China Data Center Conference is the seventh session of the Year. The theme of this Congress is "energy efficiency for first management." Editor-in-Chief of China Computer News ...

The first cloud computing conference has been held for 4 years now, and the Second China Cloud Computing Conference will be held as scheduled (June 5-7th). Each Congress will give the industry a lot of valuable knowledge, but with the erosion of time, these valuable experience has been out of sight, become a rare "cold data"! In order to reproduce these precious "legacies" from today (May 17), the author will select and share the technical concepts, technical tools and best practices shared by all the Bedo experts in the past, to share the general trend of cloud computing, how to play the best institutions in various fields, the top experts are ...

Cloud computing data Outsourcing is a problem that cannot be neglected. Many companies have either configured cloud computing or are about to configure cloud computing. Cloud computing is the latest technology to improve flexibility and reduce costs. By providing bundled, scalable software, infrastructure, data storage, and communications solutions, cloud computing vendors save money, avoid high-cost it commitments, get the scale of effective systems that are needed, and quickly configure the latest services. First, cloud computing data outsourcing need to consider the problem however, there is no free lunch, cloud computing data outsourcing can not solve legal risks (with the third ...

Many companies have either configured cloud computing or are about to configure cloud computing. Cloud computing is the latest technology to improve flexibility and reduce costs. 　　By providing bundled, scalable software, infrastructure, data storage, and communication solutions, outsourcing cloud computing vendors saves money, avoids high-cost it commitments, gets the scale of an effective system on demand, and can quickly configure the latest services. What to consider before you walk in the clouds however, without a free lunch, outsourcing cloud computing cannot solve legal risks (along with third-party awareness of data storage and transmission locations ...).
