Definition: Cloud computing refers to the delivery of computing services through the internet (i.e., the cloud). These resources include servers, storage, databases, networking, software, analytics, and intelligence. It enables individuals and businesses to use computing resources without having to invest in expensive hardware, software, and infrastructure.
Cloud Computing explained
With cloud-based storage, files can be saved to a remote database as opposed to being kept on a proprietary hard drive or local storage device. A computer or other electronic device may access data and the software needed to run it as long as it can access the internet. This enables the user to access information remotely since they have no requirement to be in a specific location to gain access to it.
In cloud computing, multiple services are provided by a third party and made available via the internet. Users can access these services on-demand, paying only for what they use and scaling up or down as required.
Types of Cloud Service
- Storage, backup, and data retrieval
- Analyzing data
- Development and test of applications
- Audio and video streaming
- Delivering software on demand
Cloud Deployment Models
Public cloud, private cloud, and hybrid cloud are the three primary cloud deployment models.
Public Cloud: The cloud infrastructure is owned and operated by a third-party service provider in this model, and the resources are shared among multiple customers over the internet. Examples of public cloud providers include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform.
Private Cloud: A private cloud is a cloud infrastructure that is solely owned and operated by a single organization. The resources are not shared with other organizations, and the infrastructure can be located on-premises or in a third-party data center. Private clouds are typically used by organizations that require higher levels of security, control, and customization.
Hybrid Cloud: A hybrid cloud is a combination of public and private cloud infrastructures. This model allows organizations to take advantage of the scalability and cost-effectiveness of the public cloud while maintaining sensitive data and critical applications on a private cloud. Organizations can mitigate the risk of data breaches and meet compliance standards with the use of a hybrid cloud.
Prior to the cloud becoming an effective alternative, organizations had to invest in, build, and maintain expensive information management infrastructure and technology. Therefore, numerous advantages come with cloud computing, such as cost savings, scalability, agility, reliability, security, and accessibility. It has revolutionized the way businesses operate, allowing them to focus on their core competencies while leaving the technical details to cloud providers.
Data security and platform security are significant concerns because software and data are stored remotely in cloud computing. Measures made to safeguard digital assets and data stored on cloud-based services are referred to as cloud security .
Any cloud-based solution must prioritize cloud security, and organizations must put in place strong security controls to protect their data and infrastructure from cyber threats.
