The overall cost of E-MapReduce consists of the following:
Cost of ECS products
Alibaba Cloud Elastic Compute Service (ECS) comes included when you purchase an E-MapReduce cluster, meaning that you do not need to prepare ECS in advance. If you are entitled to a discount for ECS, this also applies to your purchase of E-MapReduce.
Cost of E-MapReduce products
E-MapReduce provides multi-dimensional management services for clusters, including page display and control, API and SDK support, monitoring and alarms, O&M tools, and automatic back-end O&M..
Cost of the external network traffic of master nodes
In created clusters, 8 Mbps of public network bandwidth is available for master nodes (for an HA cluster, each of the two master nodes has 8 Mbps of bandwidth). Traffic is Pay-As-You-Go and is not included in the cost of the clusters. You are charged on an hourly basis for outbound traffic, but inbound traffic is free. For example, if in an hour you use 10 GB of outbound traffic on a public network, the charge is 10 x price per GB (in USD). Traffic fees may vary between regions.
