Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power,without direct active management by the user. We use the term to describe data centers available to many users over the Internet. Large clouds, predominant today, often have functions distributed over multiple locations from central servers. If the connection to the user is relatively close, they may designate it an edge server. Besides, there are 3 kinds of cloud computing:
3 Kinds of Cloud Computing
Software as a Service (SaaS)
SaaS is the most common type of cloud computing. It provides a complete, ready-to-use internet apps. Usually these need not be downloaded and installed on the desktop of each individual user, saving loads of time for technical employees. The vendor handles the maintenance and troubleshooting entirely.
Software programs perform specific functions and are generally intuitive to use. Examples include Salesforce’s suite of customer relationship management tools, Microsoft Office 365 products, Google Apps, QuickBooks, Dropbox, Zendesk, and Slack. These are fully functional productivity tools that can be customized to the users’ needs without coding or programming. Also, SaaS provides the greatest amount of customer support.
Infrastructure as a Service (IaaS)
IaaS is the most open-ended type of cloud service for organizations that want to do a lot of customization themselves. The greatest benefit of IaaS is an extra capacity, which can be access on demand for long-term or short-term needs. IaaS makes it possible for tech-savvy businesses to rent enterprise-grade IT resources and infrastructure to keep pace with growth without requiring large capital investments.
With IaaS, a third party hosts elements of infrastructure, such as hardware, servers, firewalls, and storage capacity. However, users typically bring their own operating systems and middleware. A business that is developing a new software product might choose to use an IaaS provider to create a testing environment before deploying the program in-house. Clients typically access cloud servers through a dashboard or an API. IaaS is fully self-service.
Platform as a Service (PaaS)
PaaS provides the building blocks for software creation, including development tools, code libraries, servers, programming environments and pre-configured app components. With PaaS, the vendor takes care of back-end concerns such as security, infrastructure, and data integration so users can focus on building, hosting, and testing apps faster and at lower cost.
With a platform like Salesforce, resources are standardized and consolidated so you don’t have to reinvent the wheel each time you build a new app. Multiple developers can work on the same project simultaneously. Most times, people without coding skills can create problem-solving business applications with drag-and-drop page layouts, point-and-click field creation, and customizable reporting dashboards.
