Cloud Computing for Kids

In the past, businesses and institutions could purchase and maintain their computer services and resources. The IT department would be responsible for buying, maintaining, and managing the company’s computers, storage, and networks, which required a lot of space. The systems would also get outdated progressively while better ones emerged at lower prices. As on-premises infrastructure continued to become unsustainable, cloud computing was born.

Read on to learn more about cloud computing and how it works.

What is Cloud Computing?

Cloud computing refers to accessing computing resources like servers, databases, storage, intelligence, networking, and analytics over the internet. Cloud computing comes in three key forms: public, private, and hybrid. Public cloud computing refers to web-based computing services that companies like Google and Amazon provide, while private cloud services are accessed using a secure internet connection. Hybrid cloud computing combines public and private cloud computing to give you the best of both worlds and offers more tailored IT solutions.

A distinctive characteristic of cloud computing is that it is provided and managed by someone else. Therefore, you are not responsible for computer resources such as licenses and software upgrades. You can only access cloud computing services on a subscription basis where you pay for the services whenever you need them, just like you would other utilities. The pay-as-you-go method eliminates the need for acquiring your own computer resources, especially when you have unpredictable needs.

Types of Cloud Computing

Cloud computing services come in three main types, Infrastructure as a Service, Platform as a Service, and Software as a Service. While they all have their unique differences based on what they offer, the three service models can also interact and form one comprehensive cloud computing model.

  1. Infrastructure as a Service (IaaS)

IaaS is the most common cloud computing model. It offers the fundamental cloud computing infrastructure, including storage drives, servers, processing, networks, and operating systems. Businesses can, therefore, scale their services as they deem fit, depending on their needs. It also makes it unnecessary to have hardware in the office. IaaS is available in private, public, or hybrid infrastructure and is ideal for small businesses that need to find cost-effective solutions.

  1. Platform as a Service (PaaS)

Unlike IaaS, PaaS offers both fundamental hardware as well as a software framework. However, it supports the fast and seamless development of applications so that companies can run them on their own. It is ideal for companies where developers work on multiple projects at once and is also scalable. For example, you can develop an eCommerce platform that runs entirely on the provider’s servers.

  1. Software as a Service (SaaS)

Here, the consumer uses web applications that already run on the provider’s cloud.  You can access the applications through a browser or program interface. However, the consumer does not control the underlying infrastructure or applications except for specific application settings. SaaS is ideal for applications that require a lot of mobile or web access and is great for CRM. A great example of SaaS is Google Documents. – Read more

Cloud Computing: Opportunities and Concerns

Not just transforming personal lives, but it also holds potential for big businesses

Cloud computing is a buzzword these days. As Microsoft puts it, “Cloud computing is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale.

You typically pay only for cloud services you use, helping lower your operating costs, run your infrastructure more efficiently and scale as your business needs change.” The reason for calling it cloud computing is that the cloud symbol has been in use since the 1990s to represent the Internet in computer network diagrams. So, cloud computing is nothing but computing activities carried out over the internet.

If you have been using Web-based email service, you have been using cloud computing of sorts. The email operations of accepting, forwarding, delivering, and storing email messages and attachments is carried out not by your computer (called the client) but by the email servers (computers, programs and data storage systems located elsewhere) contacted over the internet. As a matter of fact, this client-server model was developed in the 1970s, and is the basis for cloud computing. Cloud computing has the potential to transform not only our personal lives, but also the operational efficiency of small and big businesses.

Types of Cloud Computing

Public clouds: These are owned and operated by a third-party cloud service provider, which deliver their computing resources like servers and storage over the Internet, e.g., Microsoft Azure. Here, all hardware, software and other supporting infrastructure is owned and managed by the cloud provider. You access these services and manage your account using a web browser.

Private clouds: This refers to cloud computing resources used exclusively by a single business or organization, one in which the services and infrastructure are maintained on a private network. It can be physically located on the company’s on-site datacenter. Some companies also pay third-party service providers to host their private cloud.

Hybrid clouds: These combine public and private clouds, with technology that allows data and applications to be shared between them. This allows for greater flexibility, more deployment options and helps optimise your existing infrastructure, security and compliance.

Types of Cloud Computing Services

These days, access to internet allows us to access our applications and data from any device, anywhere at any time. Sitting in a café, you can view and edit your documents with your mobile, using Microsoft’s Office Web Apps, Google Docs and Zoho Office. This is the cloud computing service model ‘Software as a Service’ (SaaS).

Creative SaaS applications are music composition and audio-editing tools from Aviary, online video editors from JayCut and Pixorial, and online photo editors from Aviary and Pixlr. Most domestic users are going to need only SaaS applications. But SaaS is restrictive for businesses and companies, who need to develop and run their own software applications. For them, ‘Platform as a Service’ (PaaS) and ‘Infrastructure as a Service’ (IaaS) are on offer. – Read more
