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, individuals and organizations can access technology services on an as-needed basis from a cloud provider.

Key Characteristics of Cloud Computing

• On-demand self-service: Users can provision computing capabilities as needed without requiring human interaction with service providers.
• Broad network access: Services are available over the network and accessed through standard mechanisms that promote use by heterogeneous client platforms.
• Resource pooling: The provider’s computing resources are pooled to serve multiple consumers using a multi-tenant model.
• Rapid elasticity: Capabilities can be elastically provisioned and released to scale rapidly outward and inward with demand.
• Measured service: Cloud systems automatically control and optimize resource use by leveraging a metering capability.

Types of Cloud Computing Services

Cloud computing services are typically categorized into three main types:

1. Infrastructure as a Service (IaaS)

IaaS provides the fundamental building blocks for cloud IT. It typically offers access to networking features, computers (virtual or dedicated hardware), and data storage space. IaaS gives businesses the highest level of flexibility and management control over their IT resources.

Examples of IaaS:

• Amazon Web Services (AWS) EC2
• Microsoft Azure Virtual Machines
• Google Compute Engine

2. Platform as a Service (PaaS)

PaaS removes the need for organizations to manage the underlying infrastructure (usually hardware and operating systems) and allows you to focus on the deployment and management of your applications. This helps you be more efficient as you don’t need to worry about resource procurement, capacity planning, software maintenance, patching, or any of the other undifferentiated heavy lifting involved in running your application.

Examples of PaaS:

• Heroku
• Google App Engine
• Red Hat OpenShift

3. Software as a Service (SaaS)

SaaS provides you with a completed product that is run and managed by the service provider. In most cases, people referring to SaaS are referring to end-user applications. With a SaaS offering, you don’t have to think about how the service is maintained or how the underlying infrastructure is managed; you only need to think about how you’ll use that particular software.

Examples of SaaS:

• Salesforce
• Google Workspace (formerly G Suite)
• Microsoft Office 365

Deployment Models in Cloud Computing

Cloud computing deployments can be categorized into four main models:

1. Public Cloud

With a public cloud, all hardware, software, and other supporting infrastructure is owned and managed by the cloud provider. Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP) are examples of public clouds.

2. Private Cloud

A private cloud refers to cloud computing resources used exclusively by a single business or organization. A private cloud can be physically located on the company’s on-site datacenter, or it can be hosted by a third-party service provider. The services and infrastructure are always maintained on a private network, and the hardware and software are dedicated solely to your organization.

3. Hybrid Cloud

Hybrid clouds combine public and private clouds, bound together by technology that allows data and applications to be shared between them. This gives businesses greater flexibility and more deployment options by allowing workloads to move between private and public clouds as computing needs and costs change.

4. Multi-Cloud

A multi-cloud strategy involves using multiple cloud computing services in a single heterogeneous architecture. This can refer to the use of multiple public cloud providers, or a combination of public, private, and edge clouds to achieve specific business or technology objectives.
