CLOUD COMPUTING-Cloud computing is the on-demand availability of computing resources

Cloud computing is the on-demand availability of computing resources (such as storage and infrastructure), as services over the internet. It eliminates the need for individuals and businesses to self-manage physical resources themselves, and only pay for what they use.

Types of Cloud Computing:

1.      Public cloud: Public clouds are run by third-party cloud service providers. They offer compute, storage, and network resources over the internet, enabling companies to access shared on-demand resources based on their unique requirements and business goals.

2.      Private cloud: private clouds are built, managed, and owned by a single organization and privately hosted in their own data centers, commonly known as “on-premises” or “on-prem.” They provide greater control, security, and management of data while still enabling internal users to benefit from a shared pool of compute, storage, and network resources.

3.      Hybrid cloud: Hybrid clouds combine public and private cloud models, allowing companies to leverage public cloud services and maintain the security and compliance capabilities commonly found in private cloud architectures.

Cloud Computing Services:

v  Infrastructure as a service (IAAS): Infra structure as a service (IAAS) offers on-demand access to IT infrastructure services, including compute, storage, networking, and virtualization. It provides the highest level of control over your IT resources and most closely resembles traditional on-premises IT resources.

v  Platform as a service (PAAS): Platform as a service (PAAS) offers all the hardware and software resources needed for cloud application development. With PAAS, companies can focus fully on application development without the burden of managing and maintaining the underlying infrastructure.

v  Software as a service (SAAS): Software as a service (SAAS) delivers a full application stack as a service, from underlying infrastructure to maintenance and updates to the app software itself. SAAS solution is often an end-user application, where both the service and the infrastructure is managed and maintained by the cloud service provider.

How cloud computing can help your organization

The pace of innovation—and the need for advanced computing to accelerate this growth—makes cloud computing a viable option to advance research and speed up new product development. Cloud computing can give enterprises access to scalable resources and the latest technologies without needing to worry about capital expenditures or limited fixed infrastructure. What is the future of cloud computing? It’s expected to become the dominant enterprise IT environment.

If your organization experiences any of the following, you’re probably a good candidate for cloud computing:

·         High business growth that outpaces infrastructure capabilities

·         Low utilization of existing infrastructure resources

·         Large volumes of data that are overwhelming your on-premises data storage resources

·         Slow response times with on-premises infrastructure

·         Delayed product development cycles due to infrastructure constraints

·         Cash flow challenges due to high computing infrastructure expenses

·         Highly mobile or distributed user population.

Advantages of Cloud Computing:

It’s flexible: Due to the architecture of cloud computing, enterprises and their users can access cloud services from anywhere with an internet connection, scaling services up or down as needed.

It’s efficient: Enterprises can develop new applications and rapidly get them into production—without worrying about the underlying infrastructure.

It offers strategic value: Because cloud providers stay on top of the latest innovations and offer them as services to customers, enterprises can get more competitive advantages—and a higher return on investment—than if they’d invested in soon-to-be obsolete technologies.

It’s cost-effective: Whatever cloud computing service model is used, enterprises only pay for the computing resources they use. They don’t need to overbuild data center capacity to handle unexpected spikes in demand or business growth, and they can deploy IT staff to work on more strategic initiatives.
