Cloud Computing Definition:
Cloud Computing refers to the delivery of computing services, including storage, processing power, databases, networking, software, and more, over the internet (the cloud). Instead of owning and managing physical hardware or software infrastructure, organisations and individuals can access on-demand resources from a cloud service provider on a pay-as-you-go basis.
What is Cloud Computing?
Cloud Computing allows users to access scalable and flexible computing resources without needing to invest in, maintain, or manage physical infrastructure. Cloud environments can be categorised into different models such as Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides virtualised hardware resources like storage and servers. PaaS offers platforms that enable developers to build and deploy applications. SaaS delivers fully managed software solutions, such as email and collaboration tools, directly to end users. Cloud Computing models can also be classified into public, private, and hybrid clouds, depending on how resources are deployed and shared.
Why is Cloud Computing important?
The purpose of Cloud Computing is to enhance the efficiency, scalability, and accessibility of IT resources by delivering them over the internet. It allows businesses and users to access resources on demand, scale quickly to meet varying demands, and reduce operational costs by eliminating the need for physical infrastructure maintenance. Cloud Computing enables innovation, collaboration, and rapid deployment of new technologies, making it a key driver of digital transformation for organisations worldwide.
How does Cloud Computing work?
Cloud Computing works by delivering services over the internet from data centres managed by cloud service providers. Users access resources through web-based interfaces, APIs, or other networking tools, depending on their service model. Computing resources are virtualised, meaning they are divided and shared among multiple customers, allowing for efficient use of hardware and software. Security and access control measures are implemented to protect data and ensure compliance with regulations. Cloud service providers often offer various pricing models, such as subscription-based, pay-as-you-go, or reserved resources, giving customers flexibility in how they use and pay for services.
Cloud Computing Examples:
Examples of Cloud Computing include using online storage solutions like Google Drive or Microsoft OneDrive, accessing business applications like Salesforce and Microsoft 365, and building and deploying applications using Amazon Web Services (AWS), Microsoft Azure, or Google Cloud Platform. Cloud services enable tasks such as data analysis, machine learning model deployment, and remote collaboration, all without the need for local infrastructure.
Cloud Computing Issues:
Challenges with Cloud Computing include ensuring data security and Privacy, maintaining regulatory compliance, managing costs, and avoiding vendor lock-in. Organisations must carefully select providers that meet their security needs, offer service level agreements (SLAs) that guarantee performance, and support data portability. The dynamic nature of cloud services also requires continuous monitoring and optimisation to ensure optimal performance and cost management.
