In the world of information technology it seems that every few years there is a new concept, and this is the next big technological leap. One of the modern concepts that fit this description in the world of computing is cloud computing. However, before a company decides to move to cloud computing, it needs to make sure it understands the implications of this new offering. As with most technologies, there are many benefits to you, but in addition to understanding the benefits, you also need to assess business risks. In conducting such an assessment, it is important to keep in mind not only short-term needs, but also the long-term goals and objectives of the organization. In recent years, the Obama administration has called on all federal agencies to investigate cloud computing to see if each of them benefits. “The IOC Federal Council, led by the Office of Management and Budget (OMB) and the Federal Director of Information Technology (CIO), Vivek Kundra, has created a cloud computing initiative to help achieve the president’s goals through cloud computing.” Under pressure from the current administration, cloud computing is expected to grow in the coming years. Some studies predict that “cloud services will reach $44.2 billion in 2013, up from $17.4 billion today, according to research firm IDC.” 4 This document outlines the considerations that the organization must take into account before making a decision. use or stop using cloud computing.
Cloud Computing Review:
“Cloud computing is a model of convenient network access on demand to a shared pool of configurable computing resources (such as networks, servers, storage, applications, and services) that can be quickly delivered and released with minimal effort. interaction between departments.” This definition is one of many introduced in the IT industry, but what does it really mean? The concept of the cloud can be considered as “the concept of lease or ownership – operating costs or cost of capital.” 4
To better understand the concept of cloud computing, we’ll compare it to a more general concept: pay for electricity. Each month, a household or business uses a certain amount of electricity that is controlled by the business and the consumer is billed according to its consumption. If every household had its own source of energy, it would not be cloud computing; there is no central source of energy that households can use. If households receive electricity from a consolidated energy source (such as a power plant), it will be similar to using a cloud; many users share a resource to meet their independent needs. Using this simple example, the cloud will be like a power plant that provides customers with a pay-as-you-go infrastructure or software.
Some experts may disagree, but cloud computing is very similar to how computers were used when they first appeared on the market. With the advent of computers, computers (and related equipment) have become extremely expensive and belonged to only a few select organizations, such as universities or the Government. Few had the experience to support the installation of a separate home computer. As a result, companies will rent for a while IT resources provided by a small number of vendors and buy only what they need for what they are working on. In a similar model, cloud computing introduces the concept of buying resources as needed, and, as in the past, resources are available from a remote location. The main differences are the quality of service and the variety of services offered by cloud computing providers.
The National Institute of Standards and Technology (NIST) provides guidance to help government agencies implement the cloud. The NIST cloud model “increases the time of fail-safe work and consists of five core functions, three service models and four deployment models.” Each of these elements will be discussed in this document.
Public cloud
“Made available to the general public or a large industry group and is owned by an organization that sells cloud services.”
The public cloud is owned by a third-party vendor that sells or provides the cloud for free for use by the general public. A public cloud is the fastest way to customize an organization, but it also has a limited degree of transparency and limits personalization.
Community Cloud
“Together with different organizations and supports a specific community that shares concerns”
A community cloud is an architecture that occurs when a group of organizations come together to share resources. The community cloud is a mini-public cloud, but only a small group of organizations will be allowed to use the cloud. Unlike a public cloud, this will usually be more expensive because it will only be used in a small group of organizations, and the entire infrastructure should be in place. The community cloud is a great choice for a group of organizations, such as groups of federal agencies, that want to share resources but have more control over the security and visibility of the cloud itself.
Private cloud
“Operated exclusively for the organization” 2
A private cloud is configured to support one small organization. There is much debate about whether a private cloud should be treated as a cloud, as infrastructure and cloud management remain within the organization.
Hybrid cloud
“A composition of two or more clouds (private, public, or public) that remain unique objects but are linked by standardized or private technology that allows the use of technology that allows data and applications to be carried.” 2
The hybrid cloud allows you to manage some resources from a public cloud environment, while others are managed within a private cloud. This is usually used by an organization that wants to afford the scalability features provided by the public cloud but wants to store important or private data within the organization.
