This book provides a broad introduction to search engines by integrating five different perspectives on Web search and search engines that are usually dealt with separately: the technical perspective, the user perspective, the internet-based research perspective, the economic perspective, and the societal perspective. After a general introduction to the topic, two foundational chapters present how search tools can cover the Web's content and how search engines achieve this by crawling and processing the found documents. The next chapter on user behavior covers how people phrase their search queries and interact with search engines. This knowledge builds the foundation for describing how results are ranked and presented. The following three chapters then deal with the economic side of search engines, i.e., Google and the search engine market, search engine optimization (SEO), and the intermingling of organic and sponsored search results. Next, the chapter on search skills presents techniques for improving searches through advanced search interfaces and commands. Following that, the Deep Web and how its content can be accessed is explained. The two subsequent chapters cover ways to improve the quality of search results, while the next chapter describes how to access the Deep Web. Last but not least, the following chapter deals with the societal role of search engines before the final chapter concludes the book with an outlook on the future of Web search. With this book, students and professionals in disciplines like computer science, online marketing, or library and information science will learn how search engines work, what their main shortcomings are at present, and what prospects there are for their further development. The different views presented will help them to understand not only the basic technologies but also the implications the current implementations have concerning economic exploitation and societal impact.

Infrastructure as Code (IaC) is gaining popularity and developers today are deploying their application environments through IaC tools to the cloud. However, it can become extremely difficult and time-consuming to manage the state of the infrastructure that has been deployed. This book will provide a complete walkthrough of deploying a SpringBoot application on AWS with multiple environments like production, staging and development. Everything is orchestrated through GitHub Actions and executed through Terraform Cloud to monitor changes in your infrastructure and manage its state. You'll start by reviewing how your infrastructure can be stored in code by spinning up an EC2 server first through the console, then AWS CLI and then using Terraform. You'll then be presented with a practical scenario of setting up a simple EC2 server in a multi-environment (production, staging and development) using GitHub Actions and Terraform Cloud. In the advanced section that follows, this simple EC2 server is expanded into an application that is deployed on an AWS EKS (Elastic Kubernetes Service) using AWS RDS (Relational Database Service) exposed through an AWS ALB (Application Load Balancer) protected using AWS ACM (AWS Certificate Manager), and accessible by setting the AWS Route53. The book then builds up on this infrastructure and demonstrates how it can be deployed in a multi-environment scenario by implementing accounts through AWS organizations. You'll see how to put in restrictions through Service Control Policies, how to protect secrets using AWS Secrets Manager, and how to work with least privileges using IRSA (IAM Roles for Service Accounts). Finally, you'll make the infrastructure more observable using Graphana, Prometheus, and AWS OpenSearch, run security tools, host Route53 zones dynamically based on environments, and implement CloudWatch Alarms for various use cases.
