Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications, and services). This technology allows enterprises to get their apps up and running with minimal effort quickly. It also makes it possible for businesses to scale their IT operations on-demand, so they can easily handle sudden spikes in traffic or user demand.
The cloud computing model has transformed the way many organizations operate. It’s helped them become more agile and responsive to change while reducing costs and increasing efficiency. The cloud is also having a major impact on the IT industry as a whole. Migrating more workloads to the cloud is an essential cloud endeavor in Europe, according to EU organizations (70 percent). Following that is increasing current cloud usage to save money (59 percent) and adopting a cloud-first approach (50 percent).
Cloud environments
There are three main cloud environments: public, private, and hybrid.
Public cloud: A third-party service provider owns and operates the public cloud. It’s the most popular type of cloud environment, as it’s typically the most cost-effective option.
Private cloud: A single organization owns and operates the private cloud. It gives that organization more control over its data and applications, but it can be more expensive than the public cloud.
Hybrid cloud: The hybrid cloud combines public and private clouds. With this type of environment, organizations can choose which workloads to run in which environment, depending on their specific needs.

Let’s move on to the impact cloud computing has on the IT industry.
How does cloud computing affect the IT sector?
Cloud computing is currently driving a significant change in the IT sector. New technologies have been created, and now there are several methods to virtualize IT systems and access required applications over the Internet using web-based solutions.
So how does cloud computing affect the IT industry today?
- The nature of today’s IT jobs is changing as more and more new skills are required for positions every time. The IT staff will first have to comprehend the benefits of cloud computing and how it might be integrated into their existing business model before moving to the cloud. Security and maintenance concerns must be addressed at length with the cloud providers, as well as a strong IT department must maintain contact with them after the migration has been completed.
- There’s a need to develop customizable software. The majority of the software that businesses use is not “cloud-ready.” This is where software developers step in to create code specifically for the cloud. Additionally, cloud providers must make every effort to make this transition as seamless as possible. However, once apps are SaaS, IT staff involvement is no longer required.
- The need for IT support personnel degrades, lowering the cost of IT desktop support. A new need emerges, however, in teaching workers how to use and comprehend the new systems and apps.
- Storing data in the cloud is more secure than on-premise. Cloud-based managed cloud services providers employ security specialists to manage the apps and provide security options. To ensure that the data is secure, keep it in more than one place.
- Data maintenance is no longer needed. However, moving the data to the cloud equates to losing its physical control, as it is stored in the vendor’s data center.
Cloud computing examples
Cloud computing has grown and diversified into a wide range of services and capabilities that can meet almost any business requirement. The following are examples of cloud computing diversity and capabilities:
- Zoom and Microsoft Teams. These video and audio conferencing platforms that have gained popularity during the pandemic are actually cloud-based. They use the cloud to store recorded meetings and let users access them whenever needed.
- Microsoft 365 and Google Suite. These workspaces allow users to work simultaneously on documents, presentations, and spreadsheets kept in the cloud.
- AWS Lambda. Lambda lets developers deploy code for apps or back-end services without having to manage servers. The pay-as-you-go model expands when needed to meet real-time changes in data use and storage. Serverless computing functionality is also supported by Google Cloud Functions and Azure Functions, among other cloud providers.
- Email, Skype, Calendar, and WhatsApp. These services all use the cloud’s capacity to give users access to their personal information from anywhere in the world through a web browser or mobile app.
So, how is the cloud put to use in practice? The many services and capabilities available in current public clouds have been utilized in tons of use cases, including:
PaaS
PaaS providers offer everything you need to get up and running quickly, including servers, storage, networking, and software, saving your money on maintenance. Using these services, you’ll boost the app development speed and get yourself to higher-level programming.
IaaS
The ability to use IaaS to host IT infrastructures and access compute, storage, and network capabilities in a scalable manner. Pay-as-you-go subscription plans might assist firms in cutting costs on upfront IT expenditures.
Development & testing
Ready-made cloud environments and infrastructure let your development and testing teams simulate user traffic scenarios to evaluate software performance, security, and functionality.
Big Data analytics
Cloud storage solutions are adaptable and scalable, allowing you to get real-time data insights. For example, Google Cloud Dataproc and Amazon EMR are cloud services specializing in big data projects.
Data storage and recovery
Remote data storage and retrieval may be carried out quickly. Clients only pay for the space they actually need. As for data recovery, with the cloud, you can do it faster than on-premise, plus at a lower price.
Production workload hosting
Organizations are deploying live production applications to the public cloud. This necessitates careful design and architecture of cloud resources and services required to establish a suitable operational setting for the workload as well as its desired degree of resilience.
The bottom line
Changing the IT industry as we know it, the cloud offers many benefits for businesses of all sizes, including scalability, flexibility, reduced costs, increased efficiency, and more. While there are some concerns about security and privacy when using the cloud, these can be mitigated by using trusted providers with proper security measures in place.
As you see, cloud computing is here to stay and will only become more popular in the years ahead. In 2025, there will be nearly 200 zettabytes of data in the cloud, says Cybercrime Magazine. A zettabyte is a billion terabytes (or a trillion gigabytes). Are you ready to make the switch?
