application development and deployment methods to become Elastic Computing (Elastic Computing). its functions are similar to those of EC2's cloud Computing framework. This project is based on Linux and supports both Xen and Kernel Virtual Machine (KVM ). Enomalism provides a software stack based on the TurboGears Web application framework and Python. MongoDB MongoDB is a high-performance open-source file-oriented data storage project. It is easy to d

Article Title: Red Hat and Ubuntu advanced into cloud computing. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. This week, Red Hat and Canonical, the two largest Linux vendors, respectively announced new initiatives to provide customers with cloud computing business services. I don't know if Linux will emit a ray of light in the fog of cloud computing? RedHa

Intuit, is a more advanced project (certified by SugarCRM ). Currently, QConnector can only run on MySQL (both Windows and Linux platforms are supported), but the SQL Server version (only Windows platforms are supported) is under development. It enables the Sugar server to access QuickBooks servers over HTTP or HTTPS, so these servers can connect to the QuickBooks server normally without sharing hardware or operating systems. Remember that product vendors or third parties may provide specialize

In the next version, Scheduler will be separated to Gantt, so there is some preparation for the separation in this release.

Reply content: How do I implement bulk operations in RESTful API designs? For example, a request to delete n IDs, similar to Elasticsearch in bulk that design. There are many ways to design, borrowing Backbone.js's argument: there's more Than one means to do It, don't be too tangled. To put it simply, here are a few good things: GET /

reduced the sorting time to 23 minutes when 206 EC2 nodes were used. This means that Spark is three times faster than MapReduce in sorting the same data when one tenth is used to calculate resources! In addition, without the official PB sorting comparison, we first pushed Spark to the sorting of 1 PB of data (100,000 billion records. The result of this test is that when 190 nodes are used, the workload is completed in less than 4 hours, it also far e

Over the past few years, the use of Apache Spark has increased at an alarming rate, often as a successor to MapReduce, which can support a thousands of-node-scale cluster deployment. In-memory data processing, Apache Spark is much more efficient than mapreduce, but when the amount of data is far beyond memory, we also hear about some of the agencies ' problems with spark usage. So, together with the spark community, we've invested a lot of effort to improve spark stability, scalability, performa

Ubuntu) We can also tell HOST1 to connect HOST2, or both tell them that there is no problem, weave will automatically connect, after their service startup, we can also tell weave to connect multiple peers, you can provide multiple IP addresses, separated by a space.
