What Is Cloud Computing?


Cloud computing means storing and accessing data and programs over the internet instead of your computer's hard drive. It is the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet. Cloud computing offers faster, flexible ,and economies of scale to the clients.


Cloud computing is a popular option for people and businesses for a number of reasons including cost savings, increased productivity, speed and efficiency, performance, and security. and more...


There are many Benefits of cloud computing..


Cost savings

Cloud Computing reduces capital expenses (buying hardware and software, electricity for power and cooling) and only pay for IT as you consume it..


Deploy globally in minutes

Cloud Computing provides the right amount of IT resources in minutes (computing power, storage, bandwidth, multiple physical locations)


Performance

It is upgraded to the latest generation in a regular basis, it gives you better latency and Performance.


Security

Cloud providers offer helping protect your data, apps and infrastructure from outside threats, better than your local hard drives


Speed

Contemporary cloud computing solutions alleviate latency issues and increase speed across the board, even as time goes on and even if data processing requirements increase.


Types of Cloud Services


Cloud computing services provide users with a series of functions including:

  • Email

  • Storage, backup, and data retrieval

  • Creating and testing apps

  • Analyzing data

  • Audio and video streaming

  • Delivering software on demand

Types of cloud computing


Cloud computing is usually classified on the basis of location, or on the service that the cloud is offering.

Based on a cloud location, we can classify cloud as:

  • Public Cloud

  • Private Cloud

  • Hybrid Cloud

  • Community Cloud


Public clouds

Public clouds are owned and operated by a third-party cloud service providers, which deliver their computing resources like servers and storage over the Internet.


Private Cloud

Hosting all your computing infrastructure yourself and is not shared. The security and control level is highest while using a private network.


Hybrid clouds

Hybrid clouds using both private and public clouds,and bound together by technology that allows data and applications to be shared between them.


Community Cloud

A community cloud is shared between organizations with a common ideas or that fit into a specific community


Types of cloud services


There are mainly three broad service categories in cloud computing, include Infrastructure as a Service (IaaS), Platform as a Service (PaaS). and Software as a Service (SaaS). Each type of cloud computing provides different levels of control, flexibility, and management so that you can select the right set of services for your needs.


Infrastructure As A Service (IAAS)

The most basic category of cloud computing services. With IaaS, you can rent IT infrastructure servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider. IaaS gives you the highest level of flexibility and management control over your IT resources. so Clients can avoid the need to purchase software or servers, and instead procure these resources in an outsourced, on-demand service. IBM Cloud and Microsoft Azure are the popular examples of the IaaS system.


Platform as a service (PaaS)

Cloud provider offers hardware and software tools, usually those needed for application (create web or mobile apps,) development and managing software applications to its users as a service. In a result, client wouldn't install in-house hardware and software to develop or run a new application.

Salesforce.com and Heroku are the popular examples of the PaaS system


Software as a service (SaaS)

This types of cloud service is a method for delivering software applications over a network,usually with a web browser on their phone, tablet or PC. typically the Internet. SaaS offers that,customers don’t have to warry about underlying infrastructure and handle any maintenance Example Microsoft Office, Abobe cloud


Storage As A Service (SAAS)

Storage as a Service is a business model in which a large company rents space in their storage infrastructure to a smaller company or individual.


Cloud infrastructure


When supplying users with a cloud infrastructure, cloud services providers detach computing capabilities from hardware components, such as separating:


  • Processing power from central processing units (CPUs)

  • Active memory from random access memory (RAM) chips

  • Graphics processing from the graphics processing units (GPUs)

  • Data storage availability from disk drives or flash drives


Advantages of Cloud Computing


Cloud-based software offers companies from all sectors a number of benefits, including the ability to use software from any device either via a native app or a browser. As a result, users can carry their files and settings over to other devices in a completely seamless manner. Its also offers that users can check their email or message on any computer and even store files using services such as Dropbox and Google Drive,

and also we can back up their music, files, and photos without our local hard drive storage


Disadvantages of the Cloud Computing


Security has always been a big concern with the cloud..On other hand cloud computing companies are the main victims of natural disasters, internal bugs, and power outages, too..
