Cloud computing, an essential aspect of modern IT architecture, provides a flexible, scalable, and efficient platform for distributing IT resources via the internet. The notion is not new; it dates back to the 1960s, when network-based computers was first developed.
However, it acquired substantial popularity in the early 2000s, when big technology companies began offering commercial cloud services. Cloud infrastructure services now generate $178 billion in revenue per year, with 200 ZTB of data set to be stored by 2025.
Today, it is a vital element of company strategies across industries, offering a wide range of services from data storage to intricate processing capabilities without the need for on-premise hardware.
Key Features of Cloud Computing
Cloud computing has several distinguishing features as compared to traditional on-premise solutions.
On-demand Self-service
One of the most empowering aspects of cloud computing is on-demand self-service. Users can use resources such as server time or network storage as needed, without having to engage with each service provider. This feature improves flexibility and responsiveness, eliminating the delays that come with standard IT resource allocation.
Broad Network Access
Cloud services are available over the network and can be accessed using standard processes by both traditional and thin-client systems. This extensive availability allows for ease of usage across geographical boundaries and device varieties, empowering a mobile workforce.
Resource Pooling
Cloud computing combines physical and virtual resources, which are dynamically allotted based on user demands. There is a sense of location independence because the customer has no control or knowledge of the specific location of the offered resources but can designate location at a higher abstraction level (e.g., country, state, or datacenter). This pooling improves scalability and cost efficiency.
Rapid Elasticity
Services can be elastically provided and released, allowing for quick outward and inward scaling in response to demand. To the user, the capabilities offered for provisioning appear to be limitless and can be accessed in any quantity at any moment.
Measured Service
Cloud systems automatically control and optimize resource usage by utilizing a metering capability at a level of abstraction appropriate to the type of service (for example, storage, processing, bandwidth, and active user accounts). Resource utilization can be monitored, regulated, and reported, offering transparency to both the service provider and the end user.

Types of Cloud Computing Services
There are three primary types of cloud computing services.
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) is a type of cloud computing that delivers virtualized physical computing resources via the Internet. IaaS is one of the most adaptable cloud computing models, offering infrastructure components such as virtual server space, network connections, and bandwidth, allowing businesses to increase and reduce their resources as needed.
- IaaS providers manage physical servers, networking hardware, and data storage outside of the user’s premises. Users avoid the upfront cost and complexity of purchasing and managing physical servers and other data center hardware.
- Each resource is provided as a separate service component, and you just need to rent a specific resource for the time you require it. For example, during peak business periods, a company can scale resources up to meet rising demand and down as demand decreases, thereby optimizing costs.
- IaaS allows businesses to dramatically minimize the overhead and operating costs involved with owning, administering, and maintaining physical servers. Costs are often calculated per use, which might be less expensive than keeping machinery that is not completely utilized.
Amazon Web Services (AWS), Microsoft Azure and Google Cloud are among the most popular IaaS providers.
Platform as a Service (PaaS)
Platform as a Service (PaaS) is a platform that enables users to develop, run, and manage applications without the complexities of creating and maintaining the infrastructure required for app development and deployment.
- PaaS delivers all of the features required to support the whole web application lifecycle, including building, testing, deploying, managing, and updating inside a single integrated environment.
- Multiple concurrent users can use the same development application built on the PaaS framework. This architecture enables several teams to collaborate effortlessly.
- Built-in security features, scalability, load balancing, and failover capabilities automate many typical hardware maintenance activities.
Popular PaaS providers include Heroku, Microsoft Azure and Google App Engine.
Software as a Service (SaaS)
Software as a Service (SaaS) is a subscription-based software delivery model that uses the Internet. SaaS eliminates the requirement for businesses to install and run software on their own PCs or data centers. This removes the costs for hardware procurement, provisioning, and maintenance, as well as software license, installation, and support.
- Users can access SaaS applications from any Internet-connected device or location.
- Instead of acquiring software or additional gear to support it, clients subscribe to a SaaS solution. This subscription model typically runs on a monthly or annual basis.
- Rather than acquiring new software, users can rely on a SaaS provider to handle upgrades and patch management. This significantly minimizes the workload for in-house IT professionals.
Popular SaaS providers include Google Workspace, Microsoft 365 and Salesforce.
