It is expected that by 2020, STEM will generate 1.4 million jobs in the four major industries, and there may be a shortage of talent in 1 million jobs, accounting for 70%. Young people of the millennium will take the initiative to seek the experience, and they value effectiveness, which will enable them to become leaders among their peers ...

There is a concept of an abstract file system in Hadoop that has several different subclass implementations, one of which is the HDFS represented by the Distributedfilesystem class. In the 1.x version of Hadoop, HDFS has a namenode single point of failure, and it is designed for streaming data access to large files and is not suitable for random reads and writes to a large number of small files. This article explores the use of other storage systems, such as OpenStack Swift object storage, as ...

In the era of cloud computing, more and more machines are needed for distributed communications, although they can be easily communicated by using the HTTP protocol.

Platform as a service (PaaS) is advertised as the next phase of cloud computing evolution, thanks to the middleware and database tiers that businesses want to seek to help expand, accelerate their own developer productivity, and abstract (and, if possible, commercialize). 　　Gartner is excited about all this and believes that 2015 will be the year of PAAs Take-off, and Gartner expects global PAAs sales to reach $1.8 billion trillion next year, a sharp increase to $2.9 billion by 2016.

Cloud Management is a hot topic, and it is popular that every start-up and established vendors provide some tools to manage the cloud environment. There are monitoring tools, configuration tools, and tools in between. There are naturally foggy pieces on the market (vaporware), and it is not easy to get a clear idea. If you deploy a cloud that is fairly static or not a mission-critical environment, you may not need to configure the system dynamically. In this case, the product's built-in standard tools for adding/changing/removing resources may be more than sufficient. Several vendors have products designed specifically for cloud computing management (...).
