Principles of Cloud Design

Here is my second review/lesson about computer applications. This one is entitled 'Principles of Cloud Design' by David Clinton. David has written in the introduction it is all about efficiency and effectiveness from your cloud infrastructure. This sample book will show to some extent how to plan a cloud deployment of any kind. It also mentions about the practice behind availability, scalability, and elasticity to get the full benefit of the software driving the cloud engines. This sample book is comprised of several other authors contributing their chapters. The three chapters that I read and reviewed are all by these separate authors and their combined knowledge.

Chapter 13 in this sample is about the one premise that could be which cloud practice would be the best one to choose for a particular type of business. It also defines cloud computing services, then moving into the elasticity and scalability defining both even if they happen to be interchangeable. David has set up blocks defining all the necessary terms at various intervals in reading the text. The flowcharts that he presents are easily understood for he uses shades of blue for the components of the flowcharts.

Chapter 12 in this sample is all about, at least to me, keeping your computer programs running smoothly with all you have to do. The component of this chapter is about mainly is what is called a 'load-balancer'. This chapter also covers the hookup of 'Nodejs' in all the primary steps. Flowsheets of this procedure in the book was easy to follow and understand even with the knowledge of a beginner such as I am currently. David has also mentioned about various 'health checkups' as well to be sure applications are being done properly by your computer. After reading all the computer printouts of this it seems hard to think all of this happens within seconds when all setup.

Chapter 2 has many scenarios of what is good and when something is going wrong with the program. At times it goes step-by-step with instructions on how to handle these issues with program deployments. 'Deployments' are when new applications are being sent out and installed on computers. The flowchart on page 41 shows a system that pays attention to the agility and stability of deployments that will also allow for efficiency, predictability and stability. In the end it will be about agility and enablement of 'continuous delivery' where as new as possible version of the software is deployable at any time. The chapter also shows and compares past ways of deployments with changes that will be done on the software development. I liked how the authors made comparisons of how development is completed. The chapter also does ask and answer questions in an understandable manner for even a beginner to learn from them.

The authors also have put blue highlights of various URL's to exhibit what happens with development. In the end it is really about the efficient, safe and repeatable production of operations. David throughout this sample and the whole book have placed in boxes 'TIPS' that are given to help the reader and instructor along. In chapter 2 the author mentions an idea of 'safe experimentation' and the impact on goals, deployment, and stability on production. Also, it is really on how we accept change in the deployments and applications presented to us to use and learn. David Clinton along with other contributors have compiled a book that teaches the many facets of Cloud Design and what it takes to create the various facets for multiple uses.

To be continued with the next review on 'Exploring BitCoin'.
