"51CTO" "There is no panacea for disaster recovery problems," said Jack Bailey, engineering manager at Cloud computing provider Iland. "Whenever an outage horror story occupies the headlines of major media, managers often respond subconsciously, hoping to deploy the fastest disaster recovery product immediately," he said. "However, there are differences in the specifics of each business and its location, so rushing to choose a solution before a thorough assessment of a given condition often leads to two major sequelae-either too much."

Search giant Google, with its cloud computing technology, is at the forefront of a large data center architecture configuration. The Sun's chief technology officer, Greg Papadopoulos, used cloud computing as a spectral phenomenon called redshift (red Shift), and Sun is the only vendor in the market that offers a system architecture solution based on cloud computing ideas. Astronomers often use the Doppler effect (Doppler multiplying) or redshift to define the expansion of the universe. ...

Virtualization has injected unprecedented energy into Hadoop, from the perspective of it production management, as follows: · Deploying shared data centers with Hadoop and other applications that consume different types of resources increases overall resource utilization; • Flexible virtual machine operations enable users to dynamically create, expand their own Hadoop clusters based on datacenter resources, or reduce current clusters and release resources to support other applications if needed; With the HA, FT integration provided with the virtualization architecture, avoid ...
