In the era of digital transformation, understanding the inner workings of cloud computing has become crucial. Cloud computing, a cornerstone of modern IT, revolutionises how we access and manage data, applications and services. In this article, we’ll take a look into the fundamental mechanisms behind cloud IT services, exploring its virtualised resources, on-demand scalability and the seamless user experience it offers. Discover how this technology reshapes industries and empowers users through its intricate yet accessible architecture.
What is cloud computing?
Cloud computing is a transformative technology that provides internet-based access to a diverse range of services and resources. Instead of relying solely on local devices or servers, it harnesses remote servers located within data centres. These servers are responsible for storing and overseeing data, applications and computational tasks. Users can conveniently access these resources whenever needed, with costs proportional to usage.
Cloud computing comes with many advantages like scalability, cost efficiency and adaptability. It can revolutionise how individuals and businesses interact with, obtain and manage services and data.
What are the different types of cloud computing?
There are three types of cloud computing deployment models: private cloud, public cloud and hybrid cloud.
Private cloud
The private cloud establishes an exclusive cloud setting designed for a singular business, storing physical components either on-site or within a provider’s data centre. This model ensures restricted accessibility, offering robust control.
The benefits of private cloud computing are that it boasts tailored architecture, heightened security measures and the capability to expand virtualised computing resources as required.
Typically, a business upholds an on-premises private cloud structure, supplying cloud services to internal users via an intranet. Alternatively, the organisation might collaborate with an external cloud vendor to manage dedicated servers at a remote location, maintaining exclusivity and independence.
Public cloud
A public cloud platform is an internet-based service that offers virtualised computing resources, like storage and processing power, to multiple users and organisations. Managed by third-party providers, it operates on a shared infrastructure, offering scalability and cost-efficiency.
In addition, users access resources on a pay-as-you-go basis, avoiding the need for physical hardware investment. While public clouds offer convenience and flexibility, security measures are crucial due to shared resources. Some of the most common include Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform (GCP).
Hybrid cloud
A hybrid cloud platform combines both public and private cloud environments, allowing data and applications to be shared and transferred seamlessly between them. This approach offers flexibility by enabling organisations to utilise the private cloud for sensitive data and applications while still benefiting from the scalability and cost-efficiency of the public cloud.
A hybrid cloud setup is ideal for businesses seeking to optimise performance, security and resource allocation based on specific requirements. In fact, hybrid cloud platforms enable efficient data management and application deployment across diverse environments, enhancing overall IT capabilities.
How does cloud computing work?
Cloud computing operates through remote servers, accessed over the internet. They store, process and manage data and applications. It eliminates the need for local infrastructure, offering virtualised resources on-demand. These resources are housed in data centres maintained by cloud service providers. Users can interact with these resources through web browsers or applications, enabling remote access from various devices.
Virtualisation technology lies at the core of cloud computing, enabling multiple users to share a single physical resource by creating virtual instances. This ensures efficient resource utilisation and scalability.
Cloud services are categorised into three main models: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). These provide flexibility, cost-effectiveness and global accessibility for businesses and individuals alike, allowing users to use the model that best suits their needs.
