Understanding Cloud Computing Fundamentals

What is Cloud Computing?

Cloud computing refers to 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. Instead of owning and maintaining physical data centers and servers, you can access technology services on an as-needed basis from a cloud provider.

Key Characteristics of Cloud Computing

The fundamental characteristics that define cloud computing include:

On-demand self-service: Users can provision computing capabilities as needed without requiring human interaction with service providers
Broad network access: Capabilities are available over the network and accessed through standard mechanisms
Resource pooling: Provider's computing resources are pooled to serve multiple consumers using a multi-tenant model
Rapid elasticity: Capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in
Measured service: Cloud systems automatically control and optimize resource use by leveraging a metering capability

Types of Cloud Computing Services

Infrastructure as a Service (IaaS)

IaaS provides virtualized computing resources over the internet. It's the most basic category of cloud computing services and allows you to rent IT infrastructure—servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis. In 2026, IaaS continues to be the foundation for many cloud deployments, offering maximum flexibility and control over your IT resources.

Platform as a Service (PaaS)

PaaS provides an environment for developers to build, test, and deploy software applications without worrying about the underlying infrastructure. It includes infrastructure (servers, storage, and networking) plus middleware, development tools, business intelligence (BI) services, database management systems, and more. PaaS is particularly valuable for developers who want to focus on application development rather than infrastructure management.

Software as a Service (SaaS)

SaaS delivers software applications over the internet on a subscription basis. Cloud providers host and manage the software application and underlying infrastructure, handling maintenance like software updates and security patching. Users connect to the application over the internet, usually with a web browser on their phone, tablet, or PC. Popular examples include email services, office suites, and customer relationship management (CRM) systems.

Function as a Service (FaaS) / Serverless Computing

FaaS, also known as serverless computing, allows developers to execute code in response to events without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app. In 2026, serverless computing has matured significantly, offering even greater scalability and cost-efficiency for event-driven applications.

Cloud Deployment Models

Public Cloud

Public clouds are owned and operated by third-party cloud service providers, which deliver their computing resources like servers and storage over the internet. Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP) are examples of public clouds. In a public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. You access these services and manage your account using a web browser.

Private Cloud

A private cloud consists of computing resources used exclusively by one business or organization. The private cloud can be physically located at your organization's on-site data center, or it can be hosted by a third-party service provider. A private cloud offers greater control and security, making it ideal for organizations with strict regulatory requirements or sensitive data.

Hybrid Cloud

Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them. The hybrid model gives businesses greater flexibility, more deployment options, and helps optimize existing infrastructure, security, and compliance. In 2026, hybrid cloud strategies have become increasingly sophisticated, allowing seamless workload movement between environments.

Multi-Cloud

Multi-cloud involves using multiple cloud computing services from different providers. This approach can help avoid vendor lock-in, optimize costs by leveraging different providers' pricing models, and provide redundancy. Organizations are increasingly adopting multi-cloud strategies to take advantage of best-of-breed services from different providers.

Benefits of Cloud Computing

Cost Savings

Cloud computing eliminates the capital expense of buying hardware and software and setting up and running on-site data centers. It also reduces ongoing costs like electricity for power and cooling, IT experts for managing the infrastructure, and physical space. In 2026, cloud computing continues to offer significant cost advantages through pay-as-you-go pricing models.

Scalability and Flexibility

Cloud computing allows you to scale resources up or down based on demand. This elasticity means you can handle traffic spikes without over-provisioning resources, and scale down during quiet periods to save costs. The flexibility to quickly adapt to changing business needs is one of the most valuable aspects of cloud computing.

Global Reach

Cloud providers have data centers worldwide, allowing you to deploy your applications closer to your users for better performance. This global infrastructure also provides disaster recovery and business continuity capabilities, ensuring your services remain available even if one data center experiences issues.
