Different Types of Cloud Computing
Different Types of Cloud Computing: The delivery of computing services on demand from storage to power of processing to applications. Cloud service providers provide companies with access to applications, storage, and computing infrastructure instead of owning their infrastructure and data centers. The main benefit of using cloud computing is it helps companies in saving the costs and complexity that may occur if they own their infrastructures. But Computing can be rented and used so it helps save a good amount. Functions of large clouds distributed over many locations.
It includes storage, databases, services, and intelligence, etc. A cloud can either be public or private. The services of the cloud can be sold by anyone on the internet. The goal is to provide reliable computing services as well as reliable IT services. For proper implementation of cloud computing. it is important to have convenient hardware and software. It can also be known as on- demand computing or utility computing.
Cloud computing is such that it lets users access data over the internet via various servers, computers, systems, or databases. Connected via the internet are the front- end (the device accessing the server, browser, its network, and its software applications) the back- end (databases, servers, and computers). Backend functionality serves as a central repository for data that the front end accesses. A central server manages the communication between the front- end, and back- end. It is dependent upon the protocol that provides the facility for exchanging data.
Examples Of Cloud Computing:
- Social Sites – Whatsapp & Skype: As clouds provide remote access to users, personal data can be accessed by users on any device whenever or wherever they want to.
- Zoom: is a cloud- based platform. where people can connect using audio or video facilities, that can be saved to the cloud as they can also be recorded that can later be accessed or shared.
- Emails & Calendar: Contains data that can be accessed remotely on any device when needed.
- AWS Lambda: Is a platform for developers. where they can code without managing servers or any sort of provisioning.
- Google Docs: Documents can be accessed on any device using the internet. Work can be stored in the cloud which can later be accessed whenever needed.
- Cost Saving: As the organizations do not need to buy and maintain the infrastructures. Because it becomes easier for them to save large amounts as they do not need to invest in any sort of facilities, utilities, or hardware components. Cloud infrastructures help organizations in reducing costs related to downtime. As downtime occurs nearly zero to not, no time consumption is taken in fixing it.
- Disaster Recovery: As data loss is a common problem. If a server goes down or the system fails. Data can be lost and companies may suffer from a huge loss. By using clouds, data can be accessed via other devices or systems.
- Mobility: When data is stored in the cloud, it can be accessed from any device. At any location, and at any time. Thus, there is no need to carry laptops, USBs, or drives wherever you go.
Cloud Computing Vendors:
The most commonly used cloud service providers are:
- Microsoft Azure
- Google Cloud Platform
- Amazon Web Services
- Oracle Cloud
Types of Cloud Computing:
- Private Clouds: Services that are offered over the internet or internally to choose specific users rather. Than the general public. It is also known as “corporate cloud”. It provides scalability, elasticity and self- servicing. It’s a high level of security so that the data cannot be accessed by any third party. The drawback of the private cloud is that it is managed by the IT staff of the organization.
- Public Clouds: Offered by third- party over the public internet to people who want to use them or buy them. They can either be free or bought at various prices depending upon the size.
- Hybrid Cloud: Includes at least one private and one public cloud or even 2 or more private clouds and public clouds. Hybrid clouds can be used in many forms. A public cloud can be used for a private cloud as a backup.
- Multiclouds: Means multiple public clouds. It can be accessed by users over the internet. Each cloud is managed by a separate cloud provider. Mostly by the providers who offer cloud services. A multicloud can be a hybrid cloud. Similarly, a hybrid cloud can also be a multicloud. The question arises, how? Multiclouds can contain multiple public clouds. Whereas the hybrid cloud also contains at least one public cloud.
