Active Directory Federation Services (AD FS) is a server role in Windows Server 2008 that provides highly scalable and secure authenticated access solutions that can operate on different platforms. Even when user accounts and applications are located in different networks or enterprises, AD FS provides browsing-based customers, protected, Internet-facing paths within and outside the network. In the usual scenario: the application is on a network, and the user account is on another network. When

Let's take a closer look at these projects.Apache Hivein 2016, Hive had a contributor of more than 100 people . The team released Hive 2.0 in February and released Hive 2.1 in June. Improvements to Hive 2.0 include several improvements to Hive-on-spark, as well as performance, availa

This mode should be selected when a database such as Apache Kylin exists mode selection.

For example, Amazon public cloud (AWS) provides various services for DBaaS, including Relational Database Service (RDS), NoSQL Database Service DynamoDB, data warehouse service Redshift, and cloud-oriented memory cache service ElastiCache. In the private cloud, Trove, a part of the OpenStack DBaaS Project, provides a set of unified infrastructure to

Be too busy to save timeThe efficiency of data center management can be measured by wasted time and money. In a recent survey, 200 data center managers from the US and UK said that using tools such as data center infrastructure Management (DCIM) solutions could make their jobs "easier, faster, and cost-efficient".If applying a DCIM solution can really save time and reduce operational costs, why did the survey find that 43% of data center managers still rely on artificial methods to replace DCIM?

), such as Riak, Couchbase, or MongoDB, or even some relational databases.Tools designed to handle massive datasets are happy to use the LSM approach, which allows for fast data acquisition and performance based on hard drive fabric reads. HBase, Cassandra, Rocksdb, LevelDB and even MONGO now support this approach.The column (Column-per-file) engine for each file is commonly used for database massively parallel processing (MPP), such as redshift or ve

Twitter,coursera are in use.Tachyon: is a highly fault-tolerant Distributed file system that allows files to be reliably shared in the cluster framework at the speed of memory, just like Spark and MapReduce.

At present, real-time or quasi-real-time Big data models are more and more, technology is not advanced is not the first reason for popularity, the prosperity of community circles is the most important.

The Lens provides a unified data analysis interface. Data Analysis task segmentation is achieved by providing a single view across multiple data stores while optimizing the environment for execution. Seamless integration of Hadoop implements functionality similar to traditional data warehouses.Key features of the project: The simple metadata layer provides an abstract view layer for data storage A single shared-mode server, based on Hive meta-storage.

[2]As we saw in this article, the vast majority of Postgres's problems come from the Append only mode, which is too redundant for the heap structure.A future versi
