E-MapReduce has some practical strength over the self-built clusters. For example, it provides some convenient and controllable means to manage its clusters.
In addition, it also has the following strengths:
Easy to use
The user can select the required ECS types and disks and select the required software for automatic deployment.
The user can apply for cluster resources at the corresponding position according to the geographical location where the user or the data source is located. Alibaba Cloud ECS currently supports the following regions: China (Hangzhou), China (Shanghai), China (Qingdao), China (Beijing), China (Zhangjiakou), China (Hohhot), China (Shenzhen), Singapore, Hong Kong, Australia (Sydney), Malaysia (Kuala Lumpur), Indonesia (Jakarta), Japan (Tokyo), Germany (Frankfurt), US (Silicon Valley), US (Virginia), India, and UAE (Dubai). E-MapReduce supports all of the regions supported by Alibaba Cloud ECS.
The user can create a cluster as needed, that is, it can release the cluster after an offline task running is completed and add a node dynamically when needed.
E-MapReduce is deeply integrated with other Alibaba Cloud products (such as OSS, MNS, RDS, and MaxCompute) and can be used as the input source or output destination of the Hadoop/Spark computing engine.
E-MapReduce integrates Alibaba Cloud RAM resource permission management system, so that it can isolate the service permissions through the primary account or sub-accounts.
