Compared with the self-built Hadoop cluster, Baidu MapReduce holds the following advantages:

• Ease of use: Interface-click operation, free combination of multiple big-data, open-source components, and minute-level cluster creation.
• Elasticity: Create and dynamically adjust any size of cluster, i.e., increase the size of the cluster during the peak period to improve the computing ability and decrease the size of the cluster during the off-peak period to reduce the costs.
• Efficient management: Unique Hadoop cluster management system (HMS), which provides rich cluster monitoring and management functions.
• Openness: Full compatibility with the open-source Hadoop/Spark community, and zero-cost business migration.
• Tangible benefits: On-demand payment and prepaid service, and transparent and straightforward pricing.
• Security: Private VPC (Virtual Private Cloud) and system environment for exclusive use to ensure data security.
