Unveiling the 7 Dynamic of Cloud Computing: A Comprehensive Exploration
cloud computing definition encompasses a variety of services offered by different companies, relying on the sharing of resources through internet-enabled devices to enable the functionality of application software. It serves diverse functions over the Internet, including storage through virtual servers, virtual applications, and the authorization of desktop applications. Through resource sharing, cloud computing attains reliability and benefits from economies of scale. The two primary models of cloud computing are service-based and deployment-based, with the former focusing on services and the latter on deployment approaches.
Cloud Deployment Models
Cloud deployment models, categorized by location, play a crucial role in determining the most suitable option for meeting your organization’s needs. There are four primary types of cloud deployment models: public cloud, private cloud, hybrid cloud, and community cloud. Understanding these models is essential for making informed decisions about the ideal deployment approach for your organization.
Public Cloud, is a type of hosting in which cloud services are delivered over a network for public use. Customers do not have any control over the location of the infrastructure. The cost is shared by all users and is either free or in the form of a license policy like pay per user. Public clouds are great for organizations that require managing the host application and the various applications users use.
A private cloud refers to a cloud infrastructure exclusively utilized by a single organization. This setup provides organizations with enhanced control over security and data protection, facilitated by a firewall and internal management. Whether hosted internally or externally, private clouds are advantageous for organizations with stringent security needs, substantial management requirements, and elevated uptime expectations.
A hybrid cloud employs both private and public clouds while allowing them to function as distinct entities. Resources are efficiently managed and can be sourced internally or from external providers. Hybrid clouds are particularly advantageous for their scalability, flexibility, and security features. For instance, an organization might leverage the public cloud to engage with customers while ensuring the security of their data through a private cloud.
A community cloud is an infrastructure collectively utilized by organizations within a specific community. Members of the community typically share similar concerns regarding privacy, performance, and security. For instance, banks, government entities within a country, or trading firms might collaborate within a community cloud. This type of cloud can be managed and hosted either internally or by a third-party provider. A community cloud proves beneficial for organizations engaged in joint ventures, as it provides centralized cloud computing capabilities for managing, constructing, and executing collaborative projects.
Cloud Service Models
Cloud computing service
Cloud computing service or Cloud Software as a Service (SaaS) is a category of cloud computing that provides applications to customers or organizations via a web browser.
- The application’s data operates on a server within the network, rather than relying on an application installed on the user’s computer.
- Software under this model is typically distributed through subscription-based services.
- Examples of SaaS include Salesforce, Google Docs, Office 365, Basecamp, among others.
Cloud Infrastructure as a Service
Cloud Infrastructure as a Service, provides the hardware and usually virtualized OS to their customers.
- Software is charged only for the computing power that is utilized, usually, CPU hours used a month.
- Examples of IaaS are Amazon EC2, Rackspace, Google Compute Engine, etc.
Cloud Platform as a Service
Platform as a Service (PaaS) within the cloud context furnishes networked computers in a hosted environment and extends support for the development process.
- PaaS options typically cater to a particular programming language or development environment.
- By deploying your application in this environment, you can leverage dynamic scalability and automated database backups without requiring specific coding.
- PaaS incurs additional charges on top of Infrastructure as a Service (IaaS) costs.
- Examples of PaaS include Google App Engine, Cloud Foundry, Engine Yard, and similar platforms.
What About Cloud Printing?
Cloud printing enables wireless connectivity between your computer, tablet, smartphone, and shared printers, facilitating document printing over the internet. Organizations benefit by sharing paperless content across remote locations without the need for a wired network. Particularly advantageous for BYOD environments, where employees use diverse devices and operating systems, cloud printing enhances convenience and productivity for industries relying on cloud infrastructure.
