Question

Is there a way to start / stop an Amazon EC2 instance from Google App Engine?
I read this question In python, how do you launch an Amazon EC2 instance from within a Google App Engine app? and it seems to me that the answer there is not correct.

Basically I can’t install “boto” on the app engine.

Have you looked into KOALA? It’s (more or less) a rewrite of boto for EC2, S3, EBS, and ELB that works in App Engine. From their page:

KOALA (Karlsruhe Open Application (for) cLoud Administration) is a
software service, designed to help you working with your Amazon Web
Services (AWS) compatible cloud services and infrastructures (IaaS).
The Amazon AWS public cloud and private cloud services based on
Eucalyptus, Nimbus or OpenNebula are supported. The storage services
Google Storage and Host Europe Cloud Storage can be used with KOALA
too

KOALA helps interacting with cloud services that implement the APIs of

Elastic Compute Cloud (EC2)

Simple Storage Service (S3)

Elastic Block Store (EBS)

Elastic Load Balancing (ELB)

With KOALA the users can
start, stop and monitor their instances, volumes and elastic IP
addresses. They can also create and erase buckets inside the
S3-compatible storage services S3, Google Storage and Walrus. It’s
easy to upload, check and modify data that is stored inside these
storage services, the same way it can be done with S3Fox and the
Google Storage Manager.

KOALA itself is a service that is able to run inside the public cloud
platform (PaaS) Google App Engine and inside Private Cloud platforms
with AppScale or typhoonAE.
