Hybrid Cloud for Developers

By: Manoj Hirway

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 AWS S3 applications – Unix 


Python provides a package called boto3 that can be used to access the AWS services. We will perform the same operations on the S3 service as we did using the Windows C3 SDK. Let's begin by creating an S3 bucket using Python. 

Creating a bucket

A simple example of creating an S3 bucket using Python is as follows. We first import the boto3 Python library in our application and then create an object of type S3. Then, using this object, we simply invoke the create_bucket() function and pass the name of the bucket to be created. The Bucket parameter of the create_bucket() function is mandatory. There are other parameters that are used to set the properties of the bucket such as permissions, region, and so on. 

The following is the simplest implementation of the boto3 library, which will create a bucket named packt-pub-bucket

import boto3

s3 = boto3.resource('s3')

s3.create_bucket(Bucket='packt-pub')

Notice that we created an S3 bucket by writing only three...
