Spark Tutorial Answer Sheet
Running a notebook follow up questions
1. Record used and remaining capacity hours
Total account capacity unit hours used is 0 and remaining account capacity unit hours after
loading the data is 50.
Total account capacity unit hours used 7.7 and remaining account capacity unit hours after
Graded exercise 6 is 42.3.
2. Why did the values change or not change? Ans: The value changed because of the instance
consumes capacity unit hours.
3. What is the difference between “Computing Service” and “Environment”? Ans: Computing
service are the resources required to perform computational work in cloud. While
Environment refers to a hardware platform and the operating system that is used in an
environment.
4. What is the difference between Apache Spark Service and the IBM Analytic Engine?
5. What is the difference between Watson Studio and IBM Cloud? Ans: The Watson Studio, a
tool, are used by the data scientists, developers, and analysts to build, run, and manage AI
models, and optimize decisions anywhere on IBM Cloud. While the IBM Cloud platform
combines platform as a service (PaaS) with infrastructure as a service (IaaS) to provide an
integrated experience.
