Cloud computing is a modern software architecture where most computing tasks are performed on remote hardware and software, enabling centralized data storage and online access to various services and resources. Clouds can be classified as public, private, hybrid and personal. Cloud computing often referred as Cloud.
Types of Clouds
Public Cloud:
Managed by organizations or institutions, public clouds host hardware, software, and data centers, offering services based on utility and consumption. These services are delivered as a commodity, ensuring scalability and flexibility for users.
Private Cloud:
Owned and operated by an organization for its exclusive use, private clouds leverage cloud efficiencies while providing enhanced control over resources and avoiding multi-tenancy. Implementing a private cloud requires significant engagement to virtualize the business environment and reassess existing resources.
Hybrid Cloud:
A hybrid cloud combines two or more distinct cloud types (private, community, or public), bound together to offer the benefits of multiple deployment models. This approach allows for the integration of collocation, managed, and dedicated services with cloud resources. Most companies with private clouds evolve to manage workloads across data centers, private clouds, and public clouds, creating a hybrid environment.
Personal Cloud:
A personal cloud is a collection of digital content and services accessible from any device. It enables users to store, synchronize, stream, and share content seamlessly across platforms, screens, and locations. Built on connected services and applications, it meets consumers’ expectations for next-generation computing services.
Cloud service models can be divided into following categories:
Software as a Service (SaaS):
SaaS providers install and operate application software in the cloud, enabling users to access it via cloud clients. This model eliminates the need for local installations, simplifying maintenance and support. Cloud applications are inherently scalable, as tasks can be cloned onto multiple virtual machines in real-time to meet varying demands.
Infrastructure as a Service (IaaS):
IaaS is rapidly becoming a cornerstone of cloud adoption. Organizations utilize IaaS for a growing portion of their workloads. In this model, users deploy operating system images and application software on cloud infrastructure, maintaining and patching them as needed. IaaS services are typically billed on a utility computing basis, reflecting the resources allocated and consumed.
Platform as a Service (PaaS):
PaaS provides a robust environment for developing, testing, and deploying applications. Users can install operating system images and application software on the cloud infrastructure, with the cloud provider managing the underlying hardware and software. This model supports rapid scaling and efficient resource utilization, billed based on usage.
