Overview
Bluemix delivers virtual machines running in IBM Cloud data centers backed by a global private fiber network.
Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides secure, resizable compute capacity in the cloud. It is designed to make web-scale cloud computing easier for developers. Amazon EC2 reduces the time required to obtain and boot new server instances to minutes, allowing you to quickly scale capacity, both up and down, as your computing requirements change. Amazon EC2 changes the economics of computing by allowing you to pay only for capacity that you actually use.
Google Compute Engine delivers virtual machines running in Googles data centers and worldwide fiber network. Compute Engines tooling and workflow support enable scaling from single instances to global, load-balanced cloud computing.

  Interfaces  
  •  
UI / API / CL / SDK
Single UI : Various APIs / CLIs native to services. Differences between IAAS & PaaS environment
Webbased UI, API Available, CLI Available for Windows/Mac/Linux, SDK Available for different platforms
Webbased UI, API Available, CLI Available for Windows/Mac/Linux, SDK Available for different platforms, Cloud Shell
  •  
Common API service keys
Multiple API service keys
AWS Users can create their own API Access keys; these keys can be shared
GCP Users can create their own API Access keys; these keys can be shared
  Monitoring  
  •  
General Service monitoring
Available, but inconsistent IAAS & PAAS service monitoring
Every EC2 instance includes the following service quality services with a frequency of 1 minute: StatusCheckFailed, StatusCheckFailed_Instance, StatusCheckFailed_System
Stackdriver can do in-guest and Service monitoring
  •  
VM Service monitoring
Guest OS agent based (Nimsoft)
Every EC2 instance sends basic metrics to CloudWatch every five-minutes. More metrics and one-minute monitoring are available at cost.
Every GCP instance sends basic metrics to Stackdriver. More metrics and one-minute monitoring are available at cost.
  •  
Actions / Event logging
Limited capability (agent based)
Logging for EC2 instances is possible with the service CloudWatch Logs
Logging for GCP instances is possible with the service Stackdriver Logs
  Admin  
  •  
Identity & Access Management
Centralised IAM
AWS Identity and Access Management (IAM)
  •  
Multi factor authentication support
Only for IAAS
Supported
Google 2 step authentication
  •  
Granular Access Control
Configurable access control to IAAS
Using AWS Identity and Access Management (IAM) a very granular access control is possible. The default for every user and role is no access; you have to define every access control.
