Cloud Computing

Intro

Cloud computing is a new form of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., computer networks, servers, storage, applications and services), which can be rapidly provisioned and released with minimal management effort. Basically, Cloud computing allows the users and enterprises with various capabilities to store and process their data in either privately owned cloud , or on a third-party server in order to make data accessing mechanisms much more easy and reliable. Data centers[3] that may be located far from the user–ranging in distance from across a city to across the world.

Importance Of Cloud Computing

If you want to stay updated with the happiness in technology world ,

then you must be familiar with cloud computing. If not, then you must have heard

about it, at least. This term is viral on the web nowadays and by seeing it

rolling over the web, you might have got confused about what does cloud computing

mean?

Well, in the simplest words, the cloud computing is about storing the files and

resources on a server and then accessing it from anywhere in the world via

Internet. You might know that in the flow charts,was represented by ‘cloud’.

Therefore, the existence of term ‘cloud’ clearly .

Access your Data Anywher

If I am asked to select the biggest importance of cloud computing, then this point will be my choice. Come on, saving the data from one place, and then getting the power to access it from any corner of the world, is none less than a dream. Being able to access your data anywhere is especially useful when used as a means of disaster recovery to get back on your feet after an unforeseen disaster. You need not to have physical access to the system from where you saved the data. All is saved in the cloud, and you can access it from anywhere, anytime via Internet.

Disadvantages Of Cloud

1] Possible Downtime:-

Cloud computing makes your small business dependent on the reliability of your Internet connection. When it's offline, you're offline. If your internet service suffers from frequent outages or slow speeds, cloud computing may not be suitable for your business.

2] Security Issues:-

How safe is your data? Cloud computing means internet computing. So you should not be using cloud computing applications that involve using or storing data that you are not comfortable having on the internet. Established cloud computing vendors have gone to great lengths to promote the idea that they have the latest, most sophisticated data security systems possible as they want your business and realize that data security is a big concern; however, their credibility in this regard has suffered greatly in the wake of NSA snooping scandals.

4] Cost (Data Transfer Costs) :-

If your business involves transferring large amounts of data, be aware that while transferring data to the cloud (inbound) is free, outbound data transfers over the basic monthly allowance are charged on a per GB basis. If your business requirements will include regularly downloading large amounts of data from your cloud applications or data storage, the additional costs can add up.

Advantages Of Cloud

1] Reliability :-

With a managed service platform, cloud computing is much more reliable and consistent than in-house IT infrastructure. Most providers offer a Service Level Agreement which guarantees 24/7/365 and 99.99% availability. Your organization can benefit from a massive pool of redundant IT resources, as well as quick failover mechanism - if a server fails, hosted applications and services can easily be transited to any of the available servers.

2] Mobility :-

Cloud computing allows mobile access to corporate data via smartphones and devices, which, considering over 2.6 billion smartphones are being used globally today, is a great way to ensure that no one is ever left out of the loop. Staff with busy schedules, or who live a long way away from the corporate office, can use this feature to keep instantly up-to-date with clients and coworkers.

3] Automatic software updates:-

For those who have a lot to get done, there isn’t anything more irritating than having to wait for system update to be installed. Cloud-based applications automatically refresh and update themselves, instead of forcing an IT department to perform a manual organization-wide update. This saves valuable IT staff time and money spent on outside IT consultation. PCWorld lists that 50 percent of cloud adopters cited requiring fewer internal IT resources as a cloud benefit.

4] Disaster recovery :-

One of the factors that contributes to the success of a business is control. Unfortunately, no matter how in control your organization may be when it comes to its own processes, there will always be things that are completely out of your control, and in today’s market, even a small amount of unproductive downtime can have a resoundingly negative effect. Downtime in your services leads to lost productivity, revenue, and brand reputation.
