Comprehensive utilization of Nagios, ganglia and splunk cloud computing platform monitoring system, with error alarm, performance tuning, problem tracking and automatic generation of operational dimension report function. With this system, you can easily manage the Hadoop/hbase cloud computing platform. Cloud computing has long been not a conceptual phase, with large companies buying a large number of machines to begin formal deployments and operations. And the performance of hundreds of powerful servers, for operational management has brought great challenges. If there is no convenient monitoring and alarm platform, for administrators as if ...

"Editor's note" in the famous tweet debate: MicroServices vs. Monolithic, we shared the debate on the microservices of Netflix, Thougtworks and Etsy engineers. After watching the whole debate, perhaps a large majority of people will agree with the service-oriented architecture. In fact, however, MicroServices's implementation is not simple. So how do you build an efficient service-oriented architecture? Here we might as well look to mixrad ...

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 ...

With the advent of new technologies such as cloud computing and virtualization, the evolution of data centers may turn itself into a very different environment. However, any data center that operates smoothly and successfully always requires some basic elements. 　　Whether the scale of the data center is like a vertical wardrobe or a plane, or even rumors that Google is building a yacht-type data center, these elements are critical. 1, environmental control standardization, predictable environment is the cornerstone of any High-quality data center. It's not just about getting the equipment to cool down and maintaining the right humidity (according to Wikipedia, recommend ...)

Apache Hadoop is now widely adopted by organizations as the industry standard for MapReduce implementations, and the Savanna project is designed to allow users to run and manage Hadoop over OpenStack. Amazon has been providing Hadoop services over EMR (Elastic MapReduce) for years. Savanna needed information from users to build clusters such as Hadoop's version, cluster topology, node hardware details, and some other information. In mentioning ...

With hundreds of millions of items stored on ebay, and millions of of new products are added every day, the cloud system is needed to store and process PB-level data, and Hadoop is a good choice. Hadoop is a fault-tolerant, scalable, distributed cloud computing framework built on commercial hardware, and ebay uses Hadoop to build a massive cluster system-athena, which is divided into five layers (as shown in Figure 3-1), starting with the bottom up: 1 The Hadoop core layer, Including Hadoo ...
