• Select Zone of your choice. it can be any from asia, europe or us.
• Then proceed to select Machine Type. Select f1-micro.
• Then select Boot disk image. In this case , select Ubuntu 14.04 LTS.
• Then proceed to Firewall and tick Allow HTTP traffic to allow VMs to interact in between them.
• Finally, click Create VM.

Create another VM e.g front-end following steps above.

Once you're done, proceed to ssh into back-end VM you have created earlier.

Proceed to install and run the back-end database. Enter these commands to install and run MongoDB.

• sudo apt-get update
• sudo apt-get install mongodb
• sudo service mongodb stop # The mongodb service started when you installed it. you would need to stop it.
• sudo mkdir $HOME/db ; sudo mongod --dbpath $HOME/db --port 80 --fork --logpath /var/tmp/mongodb #Create a directory for MongoDB and then run the MongoDB service in the background on port 80.

Now install and run the web app on your front-end VM.

Proceed by SSH into the VM.

Follow steps below to install and run the app.

• sudo apt-get update
• sudo apt-get install git nodejs npm
• git clone https://github.com/GoogleCloudPlatform/todomvc-mongodb.git #Clone the sample application and install application dependencies.
• cd todomvc-mongodb; npm install
