What is cloud computing? Cloud technology provides on-demand data storage and computing power that does not require direct user management. In the fast-paced world of information technology (IT), cloud computing is quickly becoming the preferred way to store, manage, and process data, both for individuals and organizations of every size. Compared to traditional IT infrastructure, cloud technology has proven to be more flexible, secure, and easily implemented while also being a more cost-effective solution.
International students interested in STEM degree programs will find that expertise in cloud computing is a lucrative, in-demand skill set. Read on to learn more about what is cloud computing, how it works, and why it is so important to organizations around the world - and how you can become qualified to work in cloud computing roles.
How Does Cloud Computing Work?
What is cloud computing and how does it work? Cloud technology refers to storing or accessing computing services, like files, data, and networks, over the internet (instead of the computer or hardware you are using). Because of the flexibility and accessibility of cloud technology, many organizations now use it extensively, particularly for data storage purposes.
It’s likely you use cloud computing software in your everyday life — every time you send an email, watch a YouTube video, or order something online, you are accessing a cloud service.
The word “cloud” refers to physical servers in data centers owned by cloud service providers, located anywhere in the world. Through a method known as virtualization, cloud computing providers are able to cater their cloud services to many different users at the same time without the users or their data interacting with each other at all.
Cloud services offer many benefits, including:
Cost efficiency — Businesses are no longer required to own physical servers on site, which can be costly to install, maintain, and manage. Cloud computing providers handle all that. Companies may also pay only for the services they need, making their IT infrastructure far more affordable. (This is especially true for small businesses.)
Reliability — When a cloud provider stores data, it is backed up in multiple servers at other data centers, which protects what’s stored from most cyber security threats (even in the case of multiple servers being compromised or lost). Cloud service providers are also better equipped to deal with any threats to data, as they tend to devote more resources to security than most other businesses.
Convenience — Through the cloud, users can access their data services anywhere, on any device, regardless of location. This especially benefits businesses operating in multiple locations around the world, as their data is centralized and accessible through the internet.
Once you have a general understanding of what is cloud computing, let’s take a look at the multiple ways to deploy cloud computing services.
A private cloud is for the exclusive use of a single organization. Its servers can be established at both the cloud service provider’s data center or the organization’s own location. Private cloud infrastructure sacrifices the cost benefits of cloud computing for the sake of security. They can be managed by a cloud service provider or by the organization itself (often at a higher cost).
Public clouds are managed by a third-party cloud provider who owns and handles all its IT infrastructure, which greatly reduces costs for users. Servers are located at the provider’s data centers which can be accessed by anyone over the internet. Due to these servers being shared by multiple organizations at once, security risks involved are higher than with other methods of deployment.
Hybrid clouds combine the benefits and services of both public and private clouds while offsetting potential downsides. Businesses employing a hybrid cloud infrastructure will have on-site servers that handle the most critical data and business processes. These on-site servers are linked to a public cloud that handles secondary needs and are even used to back up their servers. While this hybrid model has the most flexibility, it is usually very costly unless the organization already has a private cloud infrastructure in use.
While these are the primary types of cloud computing, other cloud services may be available depending on the business’s area of expertise.
Types of Cloud Services
Cloud services provide flexibility for organizations in many industries to meet operational needs and are centered around providing reliable, customizable, and safe online platforms for businesses to use in their activities. Cloud services offered are different for each organization, but usually one of three major categories:
Software as a Service (SaaS)
SaaS applications are hosted by cloud service providers and accessed by users over the internet through a web browser, instead of installing them on their devices. SaaS apps are intuitive to use and offer extensive configurations and customer support. Of the three categories, SaaS is the most prevalent, expected to account for 85% of software used by organizations by 2025. Businesses consider SaaS the most important technology for success. Examples of SaaS cloud computing software include Google Workplace and Microsoft Office 365.
Platform as a Service (PaaS)
Primarily meant for developers, PaaS provides users with a platform that has the tools required to develop their own software applications. A service provider hosts and maintains everything from hardware to software, plus the infrastructure, which the user accesses through the internet to build, test, and manage new applications quickly. Examples of popular PaaS cloud computing software include Salesforce’s Heroku and Google App Engine.
Infrastructure as a Service (IaaS)
IaaS providers offer users the basic infrastructure to build their own applications, such as a server, network, and storage. To operate with an IaaS, users need to have their own operating systems and middleware in place. Examples of IaaS technology include Google Compute Engine, Microsoft Azure, and Amazon Web Services (AWS).
Depending on the university and program you choose, a STEM degree with a concentration in cloud computing can cover many of these subjects. Students can benefit from learning advanced technical knowledge of software, IT infrastructure, data systems, and more, preparing for growing careers in cloud computing.
