Editor's Notes
- Producers of movies like Avatar, “The mummy returns”
- Instances are what are nodes in Amazon EC2
- Note down the Project ID:
- Hope you’ve been able to install the gcutil tool using the prerequisites sheet that I had sent.In case not, this is how we can do itGo to http://goo.gl/sLi7Q for instructions on how to have this installed.
- How many of you know Oauth?
- Use below only if the apache doesn’t get installed at first go.sudo yum update echo '<!doctype html><html><body><h1>Hello Cloud, Thank you Python!</h1></body></html>' | sudo tee /var/www/index.html
