Overview of this book

This book introduces you to the hybrid cloud platform, and focuses on the AWS public cloud and OpenStack private cloud platforms. It provides a deep dive into the AWS and OpenStack cloud platform services that are essential for developing hybrid cloud applications. You will learn to develop applications on AWS and OpenStack platforms with ease by leveraging various cloud services and taking advantage of PaaS. The book provides you with the ability to leverage the ?exibility of choosing a cloud platform for migrating your existing resources to the cloud, as well as developing hybrid cloud applications that can migrate virtual machine instances from AWS to OpenStack and vice versa. You will also be able to build and test cloud applications without worrying about the system that your development environment supports. The book also provides an in-depth understanding of the best practices that are followed across the industry for developing cloud applications, as well as for adapting the hybrid cloud platform. Lastly, it also sheds light on various troubleshooting techniques for OpenStack and AWS cloud platform services that are consumed by hybrid cloud applications. By the end of this book, you will have a deep understanding of the hybrid cloud platform and will be able to develop robust, efficient, modular, scalable, and ?exible cloud applications.

Developing Amazon RDS applications – Unix


The boto3 Python library provides a rich set of classes and function to manipulate RDS database instances. 

Creating an RDS instance

The RDS database instance can be created using the create_db_instance() function. It requires the parameters that define the instance such as instance identifier, master user name, master user password, instance class, type of database engine such as Oracle, MySQL, and so on, and the storage to be allocated to the instance.

The following Python code demonstrates the creation of a MySQL database instance with the name packtpub with 5 GB in size:

#!/usr/bin/env python

import boto3
rds = boto3.client('rds')
try:
        response = rds.create_db_instance(
        DBInstanceIdentifier='packtpub',
        MasterUsername='dbadmin',
        MasterUserPassword='password',
        DBInstanceClass='db.t2.micro',
        Engine='mysql',
        AllocatedStorage=5)
        print response
except Exception as error:
        print error...
