Cloud computing is the on-demand delivery of computing services—including servers, storage, databases, networking, software, analytics, intelligence, and more—over the Internet ("the cloud") to offer faster innovation, flexible resources, and economies of scale.
- On-demand self-service: Users can provision computing resources as needed without requiring human interaction with each service provider.
- Broad network access: Cloud services are accessible over the network and through standard devices.
- Resource pooling: The provider's computing resources are pooled to serve multiple customers with different physical and virtual resources dynamically assigned and reassigned according to customer demand.
- Rapid elasticity: Cloud services can be rapidly and elastically provisioned, in some cases automatically, to scale quickly up or down based on demand.
- Measured service: Cloud services are metered by the amount of resources consumed, such as compute time, storage, and network bandwidth.
Infrastructure as a service (IaaS) is the most basic cloud service model. It provides access to computing resources, such as servers, storage, and networking. Users are responsible for managing and maintaining the resources, including installing and configuring operating systems and applications.
Platform as a service (PaaS) provides a platform for developing, running, and managing applications. It includes IaaS capabilities, plus additional services such as databases, middleware, and development tools. Users do not need to manage the underlying infrastructure, but they are still responsible for managing and maintaining their applications.
Software as a service (SaaS) is the most complete cloud service model. It provides access to software applications that are hosted and managed by the cloud provider. Users do not need to manage any infrastructure or applications; they simply access the applications through a web browser or mobile device.
| Feature | IaaS | PaaS | SaaS |
|---|---|---|---|
| Computing resources | Yes | Yes | No |
| Operating system | Yes | Yes | No |
| Applications | Yes | Yes | No |
| Management responsibility | Infrastructure, OS, applications | Platform, applications | Applications only |
The major cloud service providers are:
- Amazon Web Services (AWS)
- Microsoft Azure
- Google Cloud Platform (GCP)
These providers offer a wide range of cloud services, including IaaS, PaaS, and SaaS. Some of their core services include:
- AWS: Compute (EC2), storage (S3), databases (RDS), networking (VPC), analytics (RedShift), machine learning (SageMaker), and more.
- Azure: Compute (Virtual Machines), storage (Blob Storage), databases (SQL Database), networking (Virtual Network), analytics (Synapse Analytics), machine learning (Azure ML), and more.
- GCP: Compute (Compute Engine), storage (Cloud Storage), databases (Cloud SQL), networking (Cloud Networking), analytics (BigQuery), machine learning (Vertex AI), and more.
In addition to the major cloud providers, there are also a number of smaller and more specialized cloud providers. For example, some providers focus on specific industries, such as healthcare or financial services. Others focus on specific types of cloud services, such as machine learning or data analytics.
A cloud architecture is a design that describes how cloud computing components will be deployed and managed. It includes the following components:

AWS is a cloud computing platform that offers a broad set of global compute, storage, database, analytics, application, and deployment services that help organizations move faster, lower IT costs, and scale applications. AWS's services are built to be scalable and reliable, and they can be accessed on demand from anywhere over the internet.
AWS operates a global network of data centers, called regions. Each region consists of one or more Availability Zones (AZs), which are isolated from each other to protect against service disruptions. AWS customers can choose to run their applications in a single region or in multiple regions for higher availability and redundancy.
To use AWS, customers create an AWS account and then sign up for the services they need. AWS offers a pay-as-you-go pricing model, so customers only pay for the resources they use.
EC2 (Elastic Compute Cloud) is a compute service that allows customers to launch virtual machines (VMs) in the cloud. EC2 instances can be used to run any type of application, including web servers, databases, and application servers.
Lambda is a serverless compute service that allows customers to run code without provisioning or managing servers. Lambda functions are triggered by events, such as HTTP requests, database changes, or S3 object uploads.
| Feature | EC2 | Lambda |
|---|---|---|
| Provisioning | Customers must provision and manage EC2 instances. | Customers do not need to provision or manage servers. |
| Pricing | Customers are billed for EC2 instances based on the instance type, region, and usage. | Customers are billed for Lambda functions based on the number of executions and the amount of memory used. |
| Use cases | EC2 is a good choice for applications that require persistent storage, high performance, or fine-grained control over the server environment. | Lambda is a good choice for event-driven applications, such as serverless web applications, mobile backends, and data processing pipelines. |

Microsoft Azure is a cloud computing platform that provides a wide range of services, like storage, computing, and databases, hosted in Microsoft data centers. It lets businesses build, deploy, and manage applications globally, using tools and frameworks of their choice.
Azure provides core services like Compute, which includes virtual machines and containers; Storage for data solutions like Blob and Disk Storage; Networking to manage connectivity with services like Virtual Network; and Databases including SQL Database and Cosmos DB. These core services help build, deploy, and manage applications in the cloud efficiently
Azure Resource Manager (ARM) is a RESTful API and a deployment and management service for Azure. It provides a way to organize resources, apply access control, and manage them through templates. ARM ensures resources are deployed consistently and makes it easy to monitor and control access across all resources in a solution. Developers can use ARM to automate resource management tasks and enable a consistent and repeatable deployment process.
Azure IaaS, PaaS, and SaaS Differences:
IaaS (Infrastructure as a Service):
Provides virtualized infrastructure (e.g., VMs, storage, networks). User manages: OS, applications, runtime, and data. Example: Deploying a virtual machine on Azure where you handle OS updates and configurations.
PaaS (Platform as a Service):
Offers a managed platform to develop, run, and manage applications. User focuses on applications and data; Azure manages the OS and runtime. Example: Azure App Service, where you focus on code, and Azure handles the rest.
SaaS (Software as a Service):
Delivers fully managed software applications over the internet. User only uses the software without managing infrastructure or platform details. Example: Microsoft 365, where you access tools like Word or Excel without handling updates or maintenance.
Azure Virtual Network (VNet) is a private, isolated network within Azure, connecting resources securely. It supports subnets (to segment networks), NSGs (for traffic control), VNet Peering (to link networks), and VPN Gateways (for secure on-premises connections). This setup allows safe communication between Azure resources, the internet, and on-premises networks.
Azure Active Directory (Azure AD) is Microsoft's cloud-based identity and access management service. Here’s what it does:
- User Authentication: Verifies users’ identities for access to apps and resources.
- Single Sign-On (SSO): Allows users to log in once and access multiple apps without signing in again.
- Access Management: Sets permissions for who can access what, simplifying user management.
- Device Management: Controls access for trusted devices.
- Integration: Works seamlessly with Microsoft products and thousands of third-party apps. In short, Azure AD helps manage secure access to resources efficiently.
