Global Cloud Market 2024
Cloud technology refers to the delivery of computing resources, including servers, storage, databases, networking, software, and analytics, over the internet ("the cloud"). Instead of owning and maintaining physical hardware or infrastructure, users can access these resources on-demand from cloud service providers, typically on a pay-as-you-go basis.

Key characteristics of cloud technology include:
On-Demand Self-Service: Users can provision computing resources, such as virtual machines or storage, as needed without requiring human intervention from the service provider.
Broad Network Access: Cloud services are accessible over the internet from a variety of devices, including laptops, smartphones, and tablets, using standard protocols and interfaces.
Resource Pooling: Cloud providers pool and dynamically allocate computing resources to multiple users based on demand. Resources are shared to achieve economies of scale and maximize utilization efficiency.
Rapid Elasticity: Cloud services can quickly scale up or down to accommodate changes in workload or demand. Users can easily add or remove resources without significant delays or disruptions.
Measured Service: Cloud usage is typically metered and billed based on consumption, allowing users to pay only for the resources they use. This pay-as-you-go model offers cost-efficiency and flexibility.
Cloud technology encompasses various service models:
Infrastructure as a Service (IaaS): Provides virtualized computing resources, such as virtual machines, storage, and networking, over the internet. Users can deploy and manage their applications and operating systems on the cloud infrastructure.
Platform as a Service (PaaS): Offers a platform for developing, deploying, and managing applications without the complexity of building and maintaining underlying infrastructure. PaaS providers typically offer development tools, databases, middleware, and runtime environments.
Software as a Service (SaaS): Delivers software applications over the internet on a subscription basis. Users can access and use the software through a web browser without needing to install or manage it locally. Common examples of SaaS applications include email, productivity suites, customer relationship management (CRM), and enterprise resource planning (ERP) software.
Cloud technology enables various deployment models:
Public Cloud: Infrastructure and services are owned and operated by third-party cloud service providers, who deliver resources over the internet to multiple users. Public cloud offerings are highly scalable, cost-effective, and accessible to anyone with an internet connection.
Private Cloud: Infrastructure and services are dedicated to a single organization and may be hosted on-premises or by a third-party provider. Private clouds offer enhanced control, security, and customization options compared to public clouds.
Hybrid Cloud: Combines elements of public and private clouds, allowing data and applications to be shared between them. Hybrid cloud deployments offer flexibility, scalability, and the ability to leverage both on-premises and cloud resources as needed.
