Database Clusters

This method allows the architect to complete the build locally to provide the expected workload and overflow to the on demand cloud HPC to cope with the peak load. Part 1th focuses on how system builders and HPC application developers can extend your systems and applications most efficiently. Processor cores with custom extensions and shared memory the external HPC architecture of the internet is rapidly being replaced by on-demand clustering, which leverages off-the-shelf general-purpose vector collaboration processors, converged Ethernet (each link Gbit or higher), and multicore headless ...

There are two common Cluster (clusters) architectures, one is Web/internet Cluster system, which is to place data on different hosts, that is, multiple hosts are simultaneously responsible for one service, and the other is the so-called parallel operation! Parallel operation is actually the work of the same operation, to the entire Cluster inside the CPU to perform a synchronous operation of a function. Due to the use of multiple CPUs ...

"Editor's note" Recently, Anshu and Rajkumar, from Aerospike, posted an article on the high Scalability website claiming that it could obtain the million TPS at a cost of USD 1.68 per hour, which was affected by Redis Labs's Itamar Haber Using a non-benchmark program, it seems to the author that the benchmark is a trap, so what about the Redis test results? The following is the original: one day ago, I saw from Aerospike ...

As a software developer or DBA, one of the essential tasks is to deal with databases, such as MS SQL Server, MySQL, Oracle, PostgreSQL, MongoDB, and so on. As we all know, MySQL is currently the most widely used and the best free open source database, in addition, there are some you do not know or useless but excellent open source database, such as PostgreSQL, MongoDB, HBase, Cassandra, Couchba ...

Hadoop is an open source distributed computing platform owned by the Apache Software Foundation, which supports intensive distributed applications and is published as a Apache2.0 license agreement. Hadoop: Hadoop Distributed File System HDFs (Hadoop distributed filesystem) and MapReduce (Googlemapreduce Open Source implementation) The core Hadoop provides the user with a transparent distributed infrastructure of the system's underlying details 1.Hadoop ...

MongoDB company formerly known as 10gen, founded in 2007, in 2013 received a sum of 231 million U.S. dollars in financing, the company's market value has been increased to 1 billion U.S. dollar level, this height is well-known open source company Red Hat (founded in 1993) 20 's struggle results. High-performance, easy to expand has been the foothold of the MongoDB, while the specification of documents and interfaces to make it more popular with users, this point from the analysis of the results of Db-engines's score is not difficult to see-just 1 years, MongoDB finished the 7th ...

After more than eight years of practice, from Taobao's collection business to today to support all of Alipay's core business, and in the annual "Double Eleven Singles Day" continue to create a world record for the transaction database peak processing capacity.

The scalability of the system is the main reason for promoting the development of NoSQL movement, including distributed system coordination, failover, resource management and many other features. That makes NoSQL sound like a big basket that can be stuffed with anything. Although the NoSQL movement does not bring fundamental technological changes to distributed data processing, it still leads to extensive research and practice on protocols and algorithms. It is through these attempts to gradually summarize some effective database construction methods. In this article, I will focus on the NoSQL database distributed special ...

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; A server cluster is the pooling of many servers together for the same service, which, in the client's view, is just like a server cluster can use multiple computers for parallel computing to achieve high computing speed, or multiple computers to do the backup, So that any one machine breaks the whole system or can run normally once ...

As two of the most popular technologies in the field of information management, the hardware architecture of database integration machine and large data technology is basically the same, but the software system has the essential difference, which leads to the different characteristic performance. With the rapid growth of enterprise data and the continuous improvement of users ' requirements for service level, the traditional relational database technology has shown obvious lack of ability in production practice for a long time. How to obtain high availability of massive data at reasonable cost has become a major challenge in modern it field. In order to meet this challenge, in recent years, it market ...
