HOW TO ACCESS AND USE AWS AMAZON?

ACCOUNT CREATION

We will use the Amazon Web Services (AWS) cloud for some of the labs.

There will not be one account per student, but one account per group of 5 students. 

To access your AWS console, please go to: https://cloudbachelorlecture.signin.aws.amazon.com/console

The user is Bachelor-GroupXX, where XX is your group number.

The password will be provided during class.

CREATING YOUR FIRST AWS INSTANCE

Please follow this tutorial.

SETTING UP A LOCAL DEV. ENVIRONMENT

The AWS python SDK (Boto3) uses the AWS command-line interface credentials to connect AWS. Therefore, you first need to install AWS CLI. 

To install AWS CLI run the following command:

pip3 install awscli --upgrade --user

You can test the installation by running the following command :

aws --version

Finally, log in to AWS with the AWS CLI using the following command :

aws configure

and fill up your AWS Access Key ID & AWS Secret Access Key (You can leave Default region name & Default output format to None)

Finally, you can install boto3. The following link will guide you through this installation:

RESOURCES AND CODE EXAMPLES

CREATION OF INSTANCE

`````e2 = boto3.resource('ec2')

GET THE STATUS OF AN INSTANCE

ec2= boto3.client('ec2')

response = ec2.describe_instance_status()

for instance in response['InstanceStatuses']:

  instance_id = instance['InstanceId']

  system_status = instance['SystemStatus']

  instance_status = instance['InstanceStatus']

DELETION OF AN INSTANCE

ec2.instances.filter(InstanceIds = ids).terminate()

PUSH TO S3 BUCKET

s3 = session.resource('s3')

s3.upload_file(

    'FILE_NAME', 'BUCKET_NAME', 'OBJECT_NAME',

)

READ FROM S3 BUCKET

s3 = boto3.client('s3')

s3.download_file('BUCKET_NAME', 'OBJECT_NAME', 'FILE_NAME')
