Pricing model for Amazon EMR is similar to pay-per-use but is also very simple and predictable as AWS states. Pricing is based on per-second of usage and varies from $0.011/hr. to $0.27/hr. This rate of EMR also depends on the type of instance used.
This format of pricing helps AWS users to better allocate their resources and makes way for efficient planning that focuses on maximizing productivity at limited capital.
Learn big data courses in AWS and become an expert. On this note, I would recommend you to take up the AWS Big Data certification course from Intellipaat which is an online instructor-based training of 32hrs that also accompanies 40hrs for projects and exercises.
