Article from: Listen to the Cloud blogAs our business continues to grow, our number of applications has exploded. With the growth of application explosion, the difficulty of management is increased. How to quickly complete the expansion while the business explosion is growing is a big challenge. The advent of Docker happened to solve our problem. With Docker, we can quickly complete the expansion and contraction, and the configuration is uniform and error-prone.In the Docker cluster management s

Because Docker does not provide the ability of cluster management, the landing operation of a docker cluster is not very realistic, so it is necessary to introduce the management tools of container cluster, mainstream mesosphere marathon, Google

delivering the right data at the right time. "We hope that the operating system will always be ready for scale scaling to help us get more data and extract more valuable information from it," Rahman said. "In addition, we also hope to continue to deliver data to our customers ." Start-ups also need to be brave enough to try Mesos or data center operating systems Looking at the future, Rahman said he wanted to see Mattermark migrate its operating syst

Based on Mesos + marathon as the core, combined with Docker and Nginx, the DCOs management platform is developed on this basis.

At the same time is also the earliest to reach the production available, the use of large companies marathon is the most famous is the Twitter, stability is guaranteed. Another important reason is that mesos and big data applications such as spark integration are very friendly, mesosphere recently launched a marathon-based DCOs

algorithm, run on Hadoop, can be expressed in Scala, run on Spark, and have a multiple increase in speed. In contrast, switching between MPI and Hadoop algorithms is much more difficult. (2) Functional programmingSpark is written by Scala, and the supported language is Scala. One reason is that Scala supports functional programming. This has created the Spark code concise, and secondly makes the process based on spark development, but also particularly concise. A complete mapreduce,hadoop need
