NIST Five+ Essential Characteristics, Advantages of Cloud Computing

What are the essential characteristics of cloud computing?


The general overview in this article is, If you have interested in cloud computing characteristics then you will get the best page. Cloud Computing refers to the delivery of computing services which like as you need anywhere and at any time from any remote location over the same network cloud. The National Institute of Standard and Technology (NIST) is a U.S. government agency, They have given a definition of cloud computing that is generally considered the gold standard. Rather than I will be trying to create my own definition of CIS, I always defer to the National Institute of Standard and Technology's proper definition.

What are Cloud Computing Characteristics?

Cloud Computing is associate degree on-demand network delivery access to shared the pool of configurable computing resources model for sanctioning Omnipresent, and appropriate, and also rather than buying, In additionally by the cloud computing is maintaining physical servers of the whole data information and physical knowledge about resources, possess, pieces of information and storages once as you required while from a cloud provider that may be fastly provided and delivered with nominal management effort or service supplier interaction.

Attributes of cloud computing services

  1. On-demand self-service
  2. Rapid physical property
  3. Broad network access
  4. Resource pooling
  5. Measured service

ALSO READ,


1. On-demand self-service

A shopper and buyer will be unilaterally provision computing capabilities, which like the server's time and network's storage, and automatically PRN whereas not requiring human interaction and conversation with each service provider.

2. Rapid physical property

Accomplishments are often resiliently accoutred and released, in some cases automatically, to scale rapidly outward and inward commensurate is decrease and increase with the demand. To the buyer side, the potential availability for providing often appears to be unlimited and may be appropriated in any quantity at any place and any time.

3. Broad network access

Capabilities of unit measurement are accessible over the network and accessed via the traditional or normal kinds of mechanisms that promote uses by the heterogeneous skinny or thick shopper platforms such as electronic devices and offices or other huge organizations like mobile phones, tablets, laptops, and workstations.

4. Resource pooling

The provider's cloud computing deep pocket as the area of the unit measurement was pooled (that means collaborative) to serve the different various types of customers employing a conglomerate tenant model, with wholly completely different physical and virtual resources dynamically reassigned and assigned in the step of shoppers demand. There is the way of the alleged location of independence fellow, in there, the client generally typical has no management or information over the precise are able to specify the location of the provided resources but is able to additionally specify location at the subsequent level of cloud abstraction (by country, state, or knowledge center, as an example). also the samples of resources area unit of the measurement storage, processing, memory, and network system management of matrics.

5. Measured service

Cloud systems mechanically manage and optimize resource use by investing a metering capability at the grade of abstraction that is acceptable to the multiple types of services like storage, processing, bandwidth, or active user accounts, for example. Cloud computing resources are used in devices like as monitored, then controlled, and rumored, providing transparency for each and every supplier and shopper of the utilized services.

Advantages of Cloud Computing

1. Cost

⮚Cloud computing decreases the annual costs of buying software and hardware for any device.

2. Speed

⮚We can access all the resources in just one or a few clicks and use the resources within a very short time period or minute.

3. Security

⮚Many cloud vendors provide a very huge range of securities, policies, and technologies to control strengthen, and secure our data.

4. Productivity

⮚While we are using cloud computing, we don't need to apply more patching, and also we don't need to maintain the software and hardware.

5. Reliability

⮚Data recovery and data backup are less expensive and very high for business continuity.

6. Scalability

⮚We can increase and decrease the resources according to the business requirements.



NIST Characteristics Of Cloud Computing

Cloud computing is often to use of characterized as providing three varieties of cloud computing is practicality, mentioned IaaS, PaaS, and SaaS, wherever aaS is an abbreviation or shorthand for "as a service" and repaired to the implies that the practicality is not native to the user still rather than originates elsewhere and that means a location in remote location accessed via a network. Also, you can use the storage everywhere, any time, and any place. The letters I, P, S within the acronyms talk over or hash out with differing kinds of practicality because the following subsequent list makes clear as:

  • Infrastructure as a Service
  • Platform as a Service
  • Software as a Service

1. Infrastructure as a Service (IaaS)
Offers users could make the essential building blocks of computing like a process, network property, and storage information. (Of course, you furthermore may like alternative capabilities so on completely to the support with IaaS practicality - like user accounts, usage trailing, and security.) you'd use an Associate in Nursing IaaS cloud supplier if you wish to make an like to an Associate in Nursing application from scratch and wish access or scratch to fairly low-level practicality inside the software.

2. Platform as a Service (PaaS)
Instead of giving to the low-level functions inside the cloud computing software, offers a higher-level programming framework that a developer interacts with to get the computing services of his offices or whatever which you would get your information. for example, you would instead of opening a file and writing a group of bits into that file, in an exceedingly PaaS setting the developer is merely called a perform then providers can perform with the gathering of bits of the user's information, server data, and storage of internet connectivity. The PaaS framework then handles the grunt of multiple kinds of work, like the kinds of the gap of a file, writing the bits there to the file, and ensuring that the bits are successfully received by the file system. The PaaS framework supplier takes care of this whole system backing up the information and managing the gathering of backups, for example, relieving the user of getting to finish more taxing body tasks.


3. Software as a Service (SaaS)
Software as a Service has clambered to a good higher rung on the organic process ladder than a PaaS. With the help of SaaS, your all application practicality is delivered over a network in an exceedingly pretty package. The user must do nothing overuse the application; the SaaS supplier dealt with the trouble-related task and work to make and operate the application, segregating user knowledge, providing security for every user similarly because of the overall SaaS setting, and handling a myriad of alternative details.

  • The full form of IaaS is an Infrastructure as a Service.
  • The full form of PaaS is a Platform as a Service.
  • The full form of SaaS is a Software as a Service.

As with each model, this division into I, P, and S provides bound informative leverage and seeks to create neat and clean a part that in the world is rather difficult. within the case of IPS, the model is given although as if you want to like the categories square measure cleanly outlined though they, not square of area measurement. several cloud suppliers supply services of over one sort. Amazon, above all, has begun to supply several platform-like services because it has designed out its giving, and has even ventured into a couple of full-blown application services that you just did escort SaaS. you may say that Amazon suppliers have all the 3 varieties of cloud computing.

Comparison of Cloud providers

Cloud Providers Comparision

Amazon Web Service Rackspace Azure
Introduction Amazon web services (AWS) is a collection of remote computing services that together make up a cloud computing platform, offered over the internet by Amazon.com Rackspace is managed cloud computing provider offering high percentage availability of applications based on RAID10. Azure is a cloud computing platform and infrastructure, created by Microsoft, for building, deploying, and managing applications and services through a global network of Microsoft-managed datacenters.
Virtualization Xen hypervisor Opensource (Xen, Kvm) and VMware Microsoft Hyper-V

Preventive measures Moderate Basic Basic
Reactive measures Moderate Basic Basic
Support Good and chargeable Excellent Good
Scalability Good Good Good
Reliability Good Good Average
Database RDS MySQL, MsSQL, Oracle MySQL Microsoft SQL Database
Tools/framework Amazon machine image (AMI), Java, PHP, Python, Ruby - PHP, ASP.NET, Node.js, Python



Private-versus-Public could computing

If you want to discover the combination of I, P, and S within the preceding section of confusing, therefore you would wait until you hear about the entire private-versus-public cloud computing distinction. So, note the sequence of events in cloud computing:

1. Amazon, because the first cloud computing provider is amazon, it was offered to the public for cloud computing- anyone can use it which means all the users can use cloud computing software.

2. Many Information and Technology that means IT organizations or companies, when contemplating this new Amazon Web Services creature, were asked why they might not create and offer a service like the AWS to their own users, hosted in their own data centers. This on-premise version became referred to as private cloud computing services.

3. Continuing the trend, several hosting providers thought the cloud to supply their IT customers as a segregated a part of their own data centers and let then the customers build clouds into there. this idea also can be considered private cloud computing because it is dedicated to at least one user per office or organization. On the opposite hand, because the information to and from this private cloud is running over a shared network, is the cloud truly private? yes or no.

4. Then Finally, after one bright bulb noted that companies won't choose only public or private software of the Amazon Web Services, Afer than the term hybrid was coined to ask companies using both private and public cloud environments.

As you go furthermore on your journey within cloud computing, then you will be made probably witness vociferous discussions dedicated to which of these particular cloud environments is the higher option for tutors, employees, and officers. my very own position is that regardless of where you stand on the private/public/hybrid issue, public cloud computing will undoubtedly become a big part of each and every  IT company's environment.
