The Who, What, When, Where, Why and How of

Software as a Service (Saas)

by Noel Jerke  (Author)
Format: Kindle Edition

Software as a Service (SaaS) can be defined as a model of software delivery that is generally based on a subscription. It is externally hosted and available via the cloud network of the developer. If any person wishes to use Software as a Service, they will have to pay for it in the form of routine subscriptions. As it is a returning customer business model, the demand for Software as a Service has increased exponentially over the past few years. Most of the software that people use is somehow related to or is a part of the Software as a Service model. Few of the top developers in this model include Adobe, Shopify, Salesforce, Microsoft, and Google Workspace as well.  

As a software delivery network and business model, SaaS is quite interesting. However, one has to learn the core functions and their related aspects to be a part of it. With different types of tricks and guidelines about the entire subject, anyone can make up a good fortune with it as well. The following eBook about SaaS is a complete guide and assists the readers in learning about SaaS right from the scratch. It begins with the basic knowledge about SaaS and goes up to the technical one with all of it being described in a reader-friendly and non-technical way. 

Main Themes of the Book

The book is well-structured in the form of multiple questions. Each chapter answers a key question about SaaS that the readers might be having. The six important themes discussed in this eBook include What is SaaS, History, Present, and Future of SaaS, Who are the Key Players in the SaaS industry, Where are SaaS applications used, Benefits and Drawbacks of Saas, and How the SaaS market works. 

As the book is written in the form of potential questions regarding SaaS, it becomes easy for the readers to understand and comprehend it with regard to the specific questions. Besides, it also allows for easy navigation throughout the book. The readers can instantly go to a certain part based on what question they have in mind.   

Readability Aspect of the Book

An important aspect to consider when reviewing and reading a book is how well it engages the reader as well as how easy it is for the readers to understand the content. If a book is well-written, even a complicated subject can be explained well to the readers but if a book does not carry the right readability aspect, it will even make an easy thing difficult to understand. 

As far as the readability point of this eBook is concerned, it has been written in a very reader-friendly tone. This means that you don’t have to be an expert in SaaS to understand the information provided. Even some of the technical aspects such as the architecture of SaaS, types of SaaS applications, and advanced modules are explained in a way that the readers don’t find them stuck at some point. The sentences aren’t vague, rather they are explanatory and provide proper explanation to the readers. From the reader’s point of view, this makes the book quite engaging and the reader does not feel the need to put it away on account of difficulty. 

“Multi-tenant SaaS apps refer to apps that are shared between many users who use a single instance and supporting information. Since the app and database are shared, there isn’t much room for customization and significant changes. However, multi-tenant apps have their own advantages including lower costs, efficient use of resources, less maintenance costs, larger computing capacity, and shared data centers.”

Besides, the language and tone are also very basic. No jargon or technical terms are used in this book on SaaS. Even if they are used, such as single-tenant and multi-tenant SaaS, these terms are properly explained. 

With small paragraphs, multiple headings, and subheadings, the entire book comes as a properly structured one. 

Credibility of the Book 

A keyboard with the words “Big Data”

One of the most important concerns any reader could have about a book is whether or not it is a credible one. Readers would want more validated, reliable, and accurate information and this is what marks a book highly credible as well. Upon reviewing this book, it turns out to be quite a credible one. 

Firstly, there is the use of multiple references and sources of information. These are listed at the end of the book. Throughout the text, the author has used references from multiple credible sources and studies conducted concerning SaaS. The information is backed by solid research. 

“According to a study published by BrightLocal, over 90 percent of people (18-34 years old) trust online reviews and think of them as personal recommendations”.

Secondly, the writer has written the book by including numerical data, research evidence, and theoretical ideas along with real-life examples. The use of numerical data actually proves the impact of SaaS in numerous ways. With the use of research, the point and interpretation made by the writer are validated. The most important part is that the writer has incorporated real-life examples. This justifies the point made by the writer as well as gives a better understanding to someone who cannot understand just basic concepts. 

“For example, a retail business that wants to launch an ecommerce store or businesses that need an easy-to-use and affordable collaboration tool. SaaS is also recommended if you don’t need to use apps too often like the tax software or need apps that support mobile access.”

Overview of the Book

Software success

Upon reading the entire book, here are a few comments that can be deduced. 

  • The eBook on SaaS is a well-structured and defined one. Each section provides answers to possible questions about SaaS that the reader might have earlier. The sectional division also makes it easy to navigate. 
  • The eBook on SaaS is quite a detailed one. It takes into account a wide aspect of the topic with the information being explanatory and backed by examples as well as research. The book does not become irrelevant with the detail but rather provides useful insights and detailed analysis of various concepts surrounding the SaaS technology. 
  • This book has been written in a neutral and reader-friendly tone. In terms of neutrality, the book does not appear to be persuasive towards the usage of SaaS. It just leaves the decision to the readers by providing a thorough analysis and a coherent discussion on the topic. The language used by the writer is quite easy to understand. 
  • One of the elements missing in this eBook is the pictorial illustrations and charts. While these may not be necessary for a book based on specific software technology, it still becomes important as many people find it easier to understand various concepts with pictorial illustrations, graphs, and charts.
