Cloud Computing

What is cloud computing?

Cloud computing is the supply of computing services via the Internet (the "cloud"), including servers, storage, databases, networking, software, analytics, and intelligence. This enables speedier innovation, adaptable resources, and scale economies.

How does cloud computing work?

Companies can access anything from programs to storage from a cloud service provider, renting access to them rather than owning their own computing equipment or data centres.

Utilizing cloud computing services allows businesses to by-pass the upfront costs and complexity of purchasing and maintaining their own IT infrastructure in favor of paying only for the services they actually use.

By offering the same services to a wide range of consumers, cloud computing service companies can gain enormous economies of scale.

Types of cloud computing

Public, private, and hybrid clouds are the three different kinds of clouds. Each type offers a different level of protection and calls for a different level of administration from the client.

Public cloud

In a public cloud, the complete computing infrastructure is housed on the cloud provider's property, and services are provided to the client online. Customers can easily add more users or processing power as needed and do not need to operate their own IT. In this approach, many tenants share the IT infrastructure of the cloud provider

Private cloud

One company uses a private cloud solely. It could be housed in the company's office or in the data center of the cloud service provider. For the ultimate level of protection and control, use a private cloud

Hybrid cloud

A hybrid cloud combines both public and private clouds, as the name suggests. For more protection and control, hybrid cloud customers typically host their mission-critical apps on their own servers while storing their non-mission-critical applications at the cloud provider's facility

Multicloud

The usage of multiple cloud computing and storage devices in a single architecture distinguishes multi cloud from hybrid cloud.

Cloud computing services

SaaS (software as a service), PaaS (platform as a service), and IaaS (infrastructure as a service) are the three primary categories of cloud services . There is no one-size-fits-all strategy to cloud computing; instead, it's more important to identify the best solution to meet your business's needs.

SaaS (Software as a Service)

In the SaaS model of software distribution, the cloud provider hosts the customer's applications on its servers. These applications are accessed online by the customer. SaaS users benefit from subscription to the service on a pay-per-use basis rather than purchasing and maintaining their own computing equipment.

SaaS is the best option for many firms because it enables them to quickly use the most cutting-edge technology available. The demand on internal resources is lessened by automatic updating. By adding new services or features as they expand, customers may scale services to support varying demands. For every requirement of a business, including customer experience, customer relationship management, customer service, enterprise resource planning, procurement, financial management, human capital management, talent management, payroll, supply chain management, enterprise planning, and more, a modern cloud suite offers comprehensive software.

PaaS (platform as a service)

Customers who use PaaS benefit from having access to the developer tools they require to create and maintain mobile and web applications without having to purchase or maintain the underlying infrastructure. The consumer uses a web browser to access the services, while the supplier hosts the infrastructure and middleware components.

PaaS solutions need to provide ready-to-use programming components that let developers add new functionality to their apps, including cutting-edge technologies like artificial intelligence (AI), chatbots, blockchain, and the Internet of Things (IoT). Solutions for analysts, end users, and professional IT administrators should also be included in the ideal PaaS offering. These solutions should include big data analytics, content management, database administration, systems management, and security.

IaaS (Infrastructure as a Service)

Customers can use the internet to access infrastructure services on-demand thanks to IaaS. The main benefit is that the cloud provider hosts the infrastructure parts that offer subscribers computation, storage, and network capacity, enabling them to run their workloads in the cloud. Installing, setting, securing, and maintaining any software on cloud native solutions, including database, middleware, and application software, is often the responsibility of the cloud subscriber.
