Which of the following is a cloud computing platform developed by Amazon?

Each major cloud computing platform is built and owned by a specific technology company; recognising which company owns which platform is the core of this kind of general-awareness question.

Amazon's cloud computing platform is called AWS (Amazon Web Services). It provides Infrastructure-as-a-Service and Platform-as-a-Service offerings — for example virtual servers (EC2) and storage (S3) — that let businesses rent computing resources instead of owning physical hardware.

• Azure is developed and owned by Microsoft, not Amazon.

• Cloudera is a big-data and analytics software company, not a general-purpose cloud computing platform owned by Amazon.

• Since Azure and Cloudera each belong to a different company, the option claiming all of the mentioned platforms belong to Amazon cannot be correct either.

So, among the given options, AWS is the one that is Amazon's cloud computing platform.
