AWS System Administration
After getting over the excitement of the scaling and cost-saving possibilities offered by Amazon Web Services, system administrators quickly come up against complexities and gotchas in the management of systems. How can they make sure auto-scaling kicks in when it is suppose to? How do they make sure DNS sends traffic to the right systems? How do they integrate automated management tools such as Chef and Puppet? This book is a comprehensive guide to the administrative features of AWS and how to make the most of them to minimize your administrative work. You'll learn how to configure and manage powerful AWS tools, such as CloudFormation, OpsWorks, Elastic Load Balancing, and Route 53. AWS administration is no easier than stand-alone server administration - it's just different, and very rewarding once you set up your automation right. This book shows you how. ...

Learning Python Testing
Automated testing is the best way to increase efficiency and decrease the defects of software testing. It takes away much of the effort on your part so that you can find bugs early and easily. The Python unit testing framework makes it easy to write efficient automated test cases in Python. Applications involving many paradigms and styles can be very complicated to test, but with the right tools, testing becomes the simplest part of the development process. This book starts with a short introduction to testing, and then introduces the doctest tool, both in terms of practicalities and how it fits into the testing environment. From there, the discussion proceeds to unittest.mock and mock objects, and to unittest. Next, Nose is introduced and discussed. Later on, focus turns from the tools themselves toward best practices and disciplines of testing. Finally, the integration of testing with existing build processes and toolchains is covered. By the end of this book, you will know how to ...
