Cloud Computing (2nd Edition) – eBook

Description

For many years, the image of a cloud has symbolized the complex web of communication in which software developers and network administrators engage, as data navigates the vast landscape of the Internet across different computer networks. This cloud-based abstraction has rapidly evolved, now incorporating not only physical and virtual processors but also diverse data storage options, software-as-a-service (SaaS) solutions, and mobile applications. The rise of cloud-based applications and innovative functionalities continues to reshape the IT landscape, offering lower entry costs, a pay-per-use model for processing and storage, enhanced scalability, improved performance, and greater redundancy, all while bolstering business continuity. However, with these numerous advantages arise significant security challenges and pressing IT governance issues. This comprehensive ebook, Cloud Computing, 2nd Edition (PDF), delves into these topics in detail, revealing that the dynamic realm of the cloud is just beginning to demonstrate its full potential.

**Chapter Overview**

**Chapter 1: Introducing Cloud Computing** explores the abstract nature of cloud computing and its evolution. This chapter dissects the core components of the cloud: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), illustrating each with relevant real-world examples. It also discusses key benefits, including scalability, redundancy, low entry costs, and the role of virtualization.

**Chapter 2: Software as a Service (SaaS)** highlights browser-based SaaS solutions and their myriad advantages. Features platforms like SalesForce.com for customer relationship management, Taleo for human resources, and ADP for payroll processing, among others.

**Chapter 3: Platform as a Service (PaaS)** introduces cloud-based hardware and software frameworks that empower businesses to easily transition their applications to the cloud cost-effectively, spotlighting major providers like Amazon, Google, and Microsoft.

**Chapter 4: Infrastructure as a Service (IaaS)** outlines how a cloud-based data center minimizes the necessity for large in-house facilities. By leveraging the economies of scale offered by IaaS providers, companies can significantly lower their IT operational expenses.

**Chapter 5: Identification as a Service (IDaaS)** focuses on cloud-based identity management solutions that streamline user provisioning and resource access. IDaaS aids in simplifying the user sign-on process across multiple service providers.

**Chapter 6: Data Storage in the Cloud** examines the integration of cloud-based storage and the evolution of networked storage. This chapter provides insights into cloud storage options available today, including cost-effective solutions for data backup.

**Chapter 7: Collaboration in the Cloud** investigates technologies enabling simultaneous collaboration among multiple users. It traces the evolution of from instant messaging to virtual meetings and shared documents, showcasing their transformative impact on teamwork.

**Chapter 8: Virtualization** defines the use of technologies that create the illusion that entities exist without physical presence. The chapter provides insights into virtual servers, desktops, and networks.

**Chapter 9: Securing the Cloud** addresses real-world concerns regarding data security in the cloud. This chapter discusses specific threats and essential measures businesses can take to mitigate potential risks.

**Chapter 10: Disaster Recovery and Business Continuity and the Cloud** analyzes how cloud resources enhance companies’ recovery capabilities post-disaster, offering strategies to overcome operational threats effectively.

**Chapter 11: Service-Oriented Architecture** explores how web-based services are transforming software development and deployment. It highlights various real-world services available for integration into applications.

**Chapter 12: Managing the Cloud** details the managerial responsibilities post-migration, such as auditing logs, system performance monitoring, and identifying data flow bottlenecks.

**Chapter 13: Migrating to the Cloud** discusses critical factors to assess before transitioning to the cloud, including avoiding vendor lock-in, ensuring secure remote backups, budgeting, and preparing user training.

**Chapter 14: Mobile Cloud Computing** delves into the relationship between cloud computing and mobile technology, examining how they influence each other’s growth and the common applications arising from this synergy.

**Chapter 15: Governing the Cloud** emphasizes the importance of IT governance in the realm of cloud computing, discussing strategies for implementing internal controls effectively.

**Chapter 16: Evaluating the Cloud’s Business Impact and Economics** assesses how the cloud’s cost-effectiveness and scalable model empower businesses to launch cloud solutions rapidly. This chapter evaluates its influence on operational costs and capital expenses.

**Chapter 17: Designing Cloud-Based Solutions** focuses on the need for developers to not just migrate but also design applications that leverage the cloud’s scalability and redundancy, discussing critical design considerations.

**Chapter 18: Coding Cloud-Based Applications** guides readers through the steps developers take to store and manage content in the cloud, offering practical insights.

**Chapter 19: Application Scalability** explores two primary methods for scaling applications: vertically and horizontally. The chapter emphasizes considerations for developers to enable better scalability in their designs.

**Chapter 20: The Future of the Cloud** imagines a world where cloud technology permeates everyday life, affecting our cars, televisions, and even clothing. Readers will gain insight into the limitless possibilities yet to come in cloud computing.
