boto 2.3.0 18-Mar-2012


Boto is a Python package that provides interfaces to Amazon Web Services. At the moment, boto supports:

  • Simple Storage Service (S3)
  • SimpleQueue Service (SQS)
  • Elastic Compute Cloud (EC2)
  • Mechanical Turk
  • SimpleDB
  • CloudFront
  • CloudWatch
  • AutoScale
  • Elastic Load Balancer (ELB)
  • Virtual Private Cloud (VPC)
  • Elastic Map Reduce (EMR)
  • Relational Data Service (RDS)
  • Simple Notification Server (SNS)
  • Google Storage
  • Identity and Access Management (IAM)
  • Route53 DNS Service (route53)
  • Simple Email Service (SES)
  • Flexible Payment Service (FPS)
  • CloudFormation
  • Amazon DynamoDB
  • Amazon SimpleWorkflow

The goal of boto is to support the full breadth and depth of Amazon Web Services. In addition, boto provides support for other public services such as Google Storage in addition to private cloud systems like Eucalyptus, OpenStack and Open Nebula.

Boto is developed mainly using Python 2.6.6 and Python 2.7.1 on Mac OSX and Ubuntu Maverick. It is known to work on other Linux distributions and on Windows. Boto requires no additional libraries or packages other than those that are distributed with Python. Efforts are made to keep boto compatible with Python 2.5.x but no guarantees are made.
