The chief technical officer of Schindler Yuncheng (Speedycloud) Dong at the meeting with a speech entitled "Automation extension of NoSQL cluster on the Yunping platform". Demonstrates how to create and initialize a NoSQL cluster on a cloud host, and how to detect a host failure through a monitoring system, and automatically invoke the cloud API for faulty device replacement, and finally show how to destroy a host from the command line. But because the time is hasty, did not give the small partner to leave too many time to carry on the question solution and the difficulty detailed introduction, therefore dong in ...

Auth0 is a "status as a service" start-up company, but also a heavy cloud service users. For them, service outages mean that a lot of user-managed applications cannot log in, so availability is critical to them. Recently, Auth0 Engineering director Jose Romaniello shared a cloudy architecture that they could exempt across providers from a wide range of Microsoft Azure downtime. Auth0 is a "status as a service" start-up company that allows users to ignore the underlying infrastructure for mobile ...

In Serengeti, there are two most important and most critical functions: one is virtual machine management and the other is cluster software installation and configuration management. The virtual machine management is to create and manage the required virtual machines for a Hadoop cluster in vCenter. Cluster software installation and configuration management is to install Hadoop related components (including Zookeeper, Hadoop, Hive, Pig, etc.) on the installed virtual machine of the operating system, and update the configuration files like Namenode / Jobtracker / Zookeeper node ...

Preface Having been in contact with Hadoop for two years, I encountered a lot of problems during that time, including both classic NameNode and JobTracker memory overflow problems, as well as HDFS small file storage issues, both task scheduling and MapReduce performance issues. Some problems are Hadoop's own shortcomings (short board), while others are not used properly. In the process of solving the problem, sometimes need to turn the source code, and sometimes to colleagues, friends, encounter ...

Editor's note: The development and operation as a whole to look at the DevOps engineering thought gradually in the hearts of the community, this article explores the origins and development of DevOps, from the physical machine/stand-alone virtual machine deployment, to the deployment based on IaaS, and then last year, just the emergence of container based deployment.

Some of these problems are the pitfalls of Hadoop itself (short boards), and others are improperly used.

When an enterprise is transformed into a data-driven machine, its potential is enormous: the data owned by the enterprise may be the key to gaining a competitive advantage. As a result, the security of the enterprise's data and infrastructure has become more important than ever. In many cases, companies or organizations may get what Forrester says is "toxic data". For example, a wireless company is collecting data about who is logged on to which antenna tower, how long they stay online, how much data they use, whether they are moving or stationary, and that data is available to understand the user's behavior. There is no ...
