The Definitive Guide to Cloud Computing: What is it, and How Does it Work?

Posted on

What is Cloud Computing?

Cloud computing, or the use of the Internet to transform storage, applications, and data management on physical servers and on-premises data centers into network-connected, compute-intensive services, has become an essential part of both the development of new applications and of day-to-day business.

Cloud computing allows for near-instantaneous access to a very broad range of services, delivered directly from servers that are located geographically close to users, without latency, high electricity bills, or long delivery delays. These services are delivered in standard configuration, without configuration work or customization from the user.

Why does Cloud Computing Matter?

Cloud computing has the potential to revolutionize the information technology landscape and dramatically improve the way that organizations deliver, secure, manage, and analyze IT data. What is cloud computing? Cloud computing, also referred to as Software as a Service (SaaS), offers enterprises the ability to turn computer hardware (hardware that is installed onsite) and on-premises data into software-based services (e.g., hosted applications, e-commerce sites, and online business services).

Cloud Advantages

Cloud has changed the way you build a website, how you develop and distribute content, and how you run your customer-facing applications. All you have to do is pull up a website and surf to your heart’s content. And unlike virtual machine-based solutions, you don’t have to devote your computing power to your database applications. Cloud Services Cloud computing can include a wide range of services.

The following is a list of a few of the most common:

App Services — This category includes Microsoft Exchange and SharePoint, SAP Concur, Salesforce, Google Apps, Active Directory, and the others listed above.

Hybrid Solutions — Cloud-based service offerings that involve a mixture of on-premises and cloud-based data storage and processing.

Private Clouds

Storage and Network Services: A Practical Guide The Definitive Guide to Cloud Computing: A Practical Guide provides insight into a standard data center including integration with the commercial IT infrastructure. The book focuses on business users and how the system they use in their daily work can benefit from using cloud computing services.

It is also designed to be used as a reference for building and operating a private cloud as well as a guide for migration to the cloud and a guide for selecting an appropriate cloud computing service.

The Definitive Guide to Cloud Computing: A Practical Guide provides a practical guide to the private cloud. The authors provide information on building a secure private cloud as well as using it to provide services for users.

Why Aren’t There More Private Clouds?

The current paradigm of IT is linear, where computing resources are centralized. This paradigm prevents vendors and users from scaling computing resources as demand increases.

Why Aren’t There More Hybrid Cloud Solutions? The current paradigm of IT is fragmented, where compute, storage, and networking resources are deployed to a variety of diverse hardware and software resources.

The Future of Private Clouds

Today, private clouds are beginning to shed the image of “weird hybrid cloud thingies” and are being embraced by many cloud adopters as a practical way to deploy cloud services and applications. By leveraging private cloud architectures, organizations can gain efficiency in computing, storage, and network hardware, and run mission-critical business applications without spending exorbitant amounts of capital.

The Definitive Guide to Cloud Computing provides IT managers, system architects, and IT service consumers with the information they need to understand the advantages of private cloud architecture, the options for deploying cloud infrastructure, and the means to transition to cloud-based service delivery.

Building a Practical Cloud Solution When setting out to implement a cloud computing solution, ask yourself how the solution will be used. You should also consider any key considerations for your chosen technology and integration services, which will affect the level of support you will need. Think of multiple scenarios and analyze the business processes that are required to run these scenarios.
