Cloud Computing

 What is cloud based computing?

Cloud computing is the provision of a variety of services over the Internet, including data storage, servers, databases, networks, and software. Cloud storage allows you to save files to a remote database and retrieve them on demand. Servers, storage and other digital assets are provided over the Internet.    

Users can access SaaS applications and services from anywhere using computers or mobile devices with Internet access rights.Since SaaS does not require the purchase of expensive licensed programs, users can access numerous cloud applications as needed. 

An example of SaaS is Microsoft Office 365, where all MS Office applications can be used in the browser without having to install them on the local computer.

IaaS provides users with basic IT infrastructure capabilities such as data storage, servers and hardware, all in the cloud. IaaS provides the building blocks for cloud IT by offering infrastructures such as firewalls and VLANs.    

By providing a wide range of applications and service types, SaaS replaces or extends traditional business systems, including ERP, accounting, human resources, content management systems, supply chain and inventory management, and customer relationship management (CRM).

 According to Goldstein, PaaS provides a platform on which users can develop and create their own programs and applications. 

IaaS allows users to access managed computing resources, such as networks, computing power, and data storage,” said Adam Goldstein, associate lecturer of the SNHU STEM course. 

A basic feature of the NIST cloud computing model is the sharing of computing resource pools (network, server, storage, application Programs and services) convenient, on-demand network access, can be quickly deployed and deployed, only minimal management or interactive work and service providers.

    

Although service-oriented architecture advocates “everything as a service” (abbreviated as EaaS or XaaS, or aas for short), cloud providers provide their “services” according to various models, including their three standard NIST models 

. … Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). In the PaaS model, the cloud service provider provides an IT platform, which usually includes an operating system, programming language runtime, database, and Web server.

Cloud service providers use the latest hardware and software to keep their systems running in ways that small businesses cannot.

    

As long as you have an Internet connection, the data stored in the cloud allows you to work anywhere. 

If your building loses power and the Internet fails, you can still access the cloud by moving to a location where you can access the Internet. 

If you have a work computer and an Internet connection, you will be able to access data stored in the cloud. 

Cloud is just a phrase used to describe a computer network that runs programs or applications running on connected servers, rather than local computers or smartphones.

    

Cloud computing is a form of computing in which networks, data storage, applications, security and development tools are available over the Internet, as opposed to a local computer or server in your organization.

 Cloud based computing is on-demand access over the Internet to IT resources (applications, servers (physical servers and virtual servers), data warehouses, development tools, networking functions, etc.)

 hosted in a remote data center operated by a cloud provider services (or CSP). 

These resources include tools and applications such as data warehouse, servers, databases, networks, and software.

When archiving data or running programs from the hard drive, this is called local storage and processing. Everything you need is by your side, which means that other users on this computer or local network can quickly and easily access your data. The Internet has become the cloud, and voila: your data, your work, and your applications can be accessed from any device you can connect to the Internet, no matter where you are in the world. 

Companies can replace expensive server centers and IT departments with fast Internet connections, allowing employees to interact with online clouds to complete their tasks.

    

Rather than owning their own IT infrastructure or data center, companies can lease access to everything from applications to storage from a cloud provider. 

The specific benefits depend on the type of cloud service being used, but essentially, using cloud services means that companies do not need to buy or maintain their own IT infrastructure. 

Moving to the cloud is cost effective as it does not require the purchase of new hardware or software. For basic applications like email, it might make sense to move to a cloud provider rather than relying on your own expertise.

    

The problem is that these solutions tend to limit customers to general services such as storage and computing, while ignoring the set of services that make each cloud unique. 

Another notable feature of the cloud is that the processing, storage, network, and integration functions of each SaaS, IaaS, and PaaS product are actually owned by the provider and provided as a subscription-based service according to customer requirements.

Some users store all applications and data in the cloud, while others use a hybrid model, storing some applications and data on a private server, while other applications and data are stored in the cloud. 

Private cloud combines many advantages of cloud computing, including flexibility, scalability, and ease of service delivery, as well as access control, security, and local infrastructure resource provision.

A private cloud is a private network or data center that provides hosting services for a limited number of people with specific access rights and permission settings.

Common private cloud technologies and vendors include VMware and OpenStack. Public cloud providers own, operate, and assume full responsibility for the data centers, hardware, and infrastructure that run their customers’ workloads, and usually provide high-bandwidth network connections to achieve high-performance and fast access to applications and data. …

A private cloud requires an organization to build and maintain its underlying cloud infrastructure; only internal users of the private cloud perceive it as a cloud computing service. 

Every cloud application has a host, and the hosting company is responsible for maintaining huge data centers that provide the security, storage capacity, and processing power needed to store all the information users send to the cloud. The most common is to run workloads remotely over the Internet in a commercial vendor’s datacenter, also known as the “public cloud” model.

 

Different types of cloud computing :

  • public
  • personal
  • hybrid. 

Each kind calls for a extraordinary degree of patron control and affords a extraordinary degree of safety. 

Public cloud

Public cloud is a type of cloud computing in which cloud providers provide available computing resources, from SaaS applications to individual virtual machines (VM), non-operating system computing hardware, enterprise-level infrastructure and platforms. Users on the public Internet. 

Private cloud 

 The personal cloud is used totally with the aid of using the company and may be hosted on the company’s vicinity or with inside the records middle of the cloud provider company. 

Private clouds offer the very best tiers of safety and manipulate.

Hybrid cloud

As the call suggests, hybrid cloud is a mixture of public and personal clouds. 

Hybrid cloud clients regularly host their mission-important commercial enterprise packages on their servers to enhance manipulate and safety. and host your secondary packages on the vicinity of the cloud company

 

Cloud Services-

Software as a Service (SaaS) :

Instead of customers putting in packages on their devices, SaaS packages are hosted on a cloud server and made to be had to customers over the Internet. use it as in case you have been the owner. 

Examples of SaaS apps encompass Salesforce, MailChimp, and Slack.

Infrastructure as a Service (IaaS): 

In this model, the organisation rentals servers and required garage from a cloud company. to create your packages. ‘

IaaS is sort of a organisation that rentals a bit of land so one can construct anything they want, however they want to offer their very own device and constructing materials. 

IaaS vendors encompass Digital Ocean, Google Compute Engine, and OpenStack.

Function as a Service (FaaS):

 FaaS, additionally referred to as Serverless Computing, breaks cloud packages into smaller additives that most effective run whilst needed a residence bit with the aid of using bit: 

for example, tenants most effective pay for the eating room at some stage in lunch, the bed room after they sleep, the dwelling room after they watch TV and whilst they’re now no longer the use of them. They do not ought to pay rent.

Platform as a Service (PaaS): 

In this model, agencies do now no longer pay for hosted packages. instead, they pay for what they want to construct their very own packages. PaaS vendors offer the whole thing over the Internet to create an application, consisting of improvement equipment, infrastructure, and working structures.

 PaaS is like renting all of the equipment and device you want. construct a residence as opposed to renting it out. PaaS examples encompass Heroku and Microsoft Azure.
