What is cloud computing? How is it useful?

Cloud computing makes it straightforward to access applications and knowledge from any place within the world and from any device with a web connection. Cloud computing offers companies scalable computing resources and thus saves their acquisition and maintenance costs.

Benefits of cloud computing

Cloud computing brings many benefits to your business as it allows you to set up a virtual office that gives you the flexibility to connect to your business anywhere, anytime. With Smartphones, tablets, accessing your data is even easier. Moving your business to the cloud has many advantages:

  • Reduced IT costs
  • Scalability
  • Business continuity
  • Collaboration efficiency
  • Flexibility of work
  • Access to automatic updates 

Cloud Computing Architecture

Cloud computing architecture refers to the components and subcomponents that are required for cloud computing. These components usually consist of a front-end platform (thick client, thin client, mobile), back-end platforms (server, storage), a cloud-based provision, and a network (internet, intranet, intercloud).

Serverless computing

Serverless computing is a structure in which code execution is controlled through a cloud provider, rather than the conventional approach of growing programs and deploying them on servers. In a manner, builders do not need to fear approximately managing, provisioning, and preserving servers whilst deploying code.

Cloud Service Providers

Cloud service providers are providers who provide information technology (IT) as a service over the Internet. It is a term used to store and access data over the internet. It does not save any data on your PC's hard drive. Cloud Companies helps you access your data from a remote server.

List of Best Cloud Computing Companies

1) Amazon Web Services.

2) ScalaHosting.

3) Kamatera.

4) Linode.

5) LiquidWeb.

6) Cloudways.

7) OVHcloud.

8) Server space.

Cloud Computing Services

Software as a Service (SaaS)

The software as a service (SaaS) service model involves the cloud provider installing and maintaining the software in the cloud and users running the software from the cloud via the Internet. User client computers do not require any particular application to be installed.

Software, since cloud applications run in the cloud. SaaS is scalable, and system administrators can upload applications to multiple servers. In the past, each customer bought their copy of the application and uploaded it to each of their servers, but SaaS allows the customer to access the application without installing the software locally. SaaS usually includes a monthly or annual fee 

Development as a Service (DaaS)

Development as a Service is based on the web, a set of tools shared by the community. This corresponds to locally installed development tools in the traditional (non-cloud computing) provision of development tools.

Platform as a Service (PaaS)

Platform as a Service is a cloud computing service that makes application platforms and databases available to users as a service. This corresponds to middleware in the traditional provision (without cloud computing) of application platforms and databases

Data as a Service (DaaS)

Data as a Service is a web-based design construct in which data in the cloud is accessed via a defined API layer. DaaS services are often viewed as a specialized subset of a data offering. 

Infrastructure as a Service (IaaS)

Infrastructure as a Service requires physical hardware and becomes completely virtual (i.e. all servers, networks, storage, and system management that exist in the cloud). This corresponds to the traditional infrastructure and hardware method (non-cloud computing) that is carried out in the cloud.

Some Cloud Computing Examples Dropbox, Google Drive, Facebook

The number of online cloud storage providers seems to be growing every day. Everyone competes for the amount of storage space they can provide to their customers.

Right now, Dropbox is the undisputed leader in optimized cloud storage that allows users to access files through their app or website with up to 1 terabyte of free space on any device. Google's email service provider Gmail, on the other hand, offers unlimited cloud storage.

Google Drive of PC is the core of the backup and sync tool. So if you've never used the Drive app, a quick explanation might be needed. You can use this new tool to sync your Google Drive cloud storage with your PC. either the entire drive or just specific files and folders.

Facebook is a mixture of both, as you can store an infinite amount of information, pictures, and videos in your profile and then easily access them on multiple devices.
