Uses Of Cloud Computing in Real Time

Cloud Computing

Every day our activities without notice we are using Cloud computing like social media, online shopping ordering products, online payments, receiving acknowledgement, billing, verifying bank account statement details.

Benefits are without wasting time and money and completing within deadline. We are not worried about the payments about theft because OTP helps us for, it’s like an interactive responsive that’s most reliable for our transactions are become more secured. The cloud computing fulfilling all the benefits without tension.

Future of Cloud Computing

Soon computers and software will become “invisible” in that they are hidden from view. We may simply have to make gestures and a camera will interpret those and provide us what we need, or we simply have to say it. Consider J.A.R.V.I.S. from the Ironman movies, you simply ask something and that information is streamed from the cloud to a projection or a monitor. Most times it could even predict what you need based on past actions and personal behavioural trends.

What is Cloud Computing

Ubuntu Operating System

I installed Ubuntu Operating system on my PC. I observed its quickly installed and load also fast. Today I would like to share about Ubuntu Operating System.

Ubuntu is Linux based operating system, developed by Debian (open source community with two key focuses – stability and security). Ubuntu is published by Canonical Ltd. who offer commercial support.

Its free sofware and named after the Southern African philosophy of ubuntu (literally, 'human-ness'), which Canonical Ltd. suggests can be loosely translated as "humanity to others" or "I am what I am because of who we all are". It uses Unity as its default user interface for the desktop.

Its free software. It supports for long term. Every new version released with updates for every six months.Ubuntu is user friendly operating system for pc’s, smartphones, tablets, Ubuntu touch edition, network servers  usually with Ubuntu server edition, which used by many users.

Ubuntu is most used operating system which is running hosted environment called “clouds”.It supports cloud management platforms.Ubuntu runs with basic hardware so old computers can also come into running condition and can give second life to them.Some software’s installed in-built:

1.    Libre office(word), calc(excel), impress(power point)
2.    Mozilla Firefox browser
3.    Thunder Bird Email-server
4.    Python software
5.    Lisp software
6.    No drivers to install
7.    Free games

Installable with the built in Ubuntu Software center is available.

No virus affects so no anti-virus software’s required.No problems of Fixing-bugs. System will run fast because it uses some resources. No need to install any drivers to install.Lots of software’s are available for free of cost.But when we buy new laptop or pc they are giving with Microsoft windows 8 they are doing business so u can ask you can choose operating system.One of the new features of Unity in Ubuntu12.0  was the shopping lens—Amazon search results displayed in the Unity dash. It was alternately described as the "Amazon controversyDell sells computers (initially Inspiron 14R and 15R laptops) pre-loaded with Ubuntu in India and China.On 12 March 2009, Ubuntu announced developer support for 3rd-party cloud management platforms, such as those used at  Amazon EC2.

Ubuntu offers Ubuntu Cloud Images which are pre-installed disk images that have been customized by Ubuntu engineering to run on cloud-platforms such as  Amazon EC2, Opentack, Microsoft Windows. Ubuntu 11.10  added focus on OpenStack as the Ubuntu's preferred IaaS offering though Eucalyptus is also supported.

When online business are growingexistence the need of cloud computing also increased. What is cloud computing? Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. Cloud computing adopts concepts from Service-oriented Architecture (SOA) that can help the user break these problems into services that can be integrated to provide a solution. Cloud computing provides all of its resources as services, and makes use of the well-established standards and best practices gained in the domain of SOA to allow global and easy access to cloud services in a standardized way. Cloud computing allow hardware and software that are managed by third-parties which are located remote location i.e entire world. Cloud computing model allows to access information and computer resources from anywhere in the world where ever internet connection availability. Deployment Models of cloud computing are four:      Private cloud: This allows more secured due to private which is limited to single organization only. 2.  Public cloud: This allows to easily accessible to general public which is less secured due to openness Ex.Email. 3.  Hybrid cloud : This is combine feature of private and public according to the requirement for critical department they use private and for general public use public cloud accessible . 4. Community cloud : This allows accessible to group of organizations. Characteristics of Cloud Computing: ON DEMAND SELF-SERVICE : Cloud Computing allows the users to use web services and resources on demand. One can logon to a website at any time and use them. BROAD NETWORK ACCESS : Since Cloud Computing is completely web based, it accessed from anywhere and at any time. RESOURCE POOLING : Cloud Computing allows multiple tenants to share a pool of resources. One can share single physical instance of hardware, database and basic infrastructure. RAPID ELASTICITY : It is very easy to scale up or down the resources at any time. Resources used by the customers or currently assigned to customers are automatically monitored and resources. It make it possible. MEASURED SERVICE : Service Models & Deployment Models are concerned with measured service. Applications: Ø        Social Networking sites like Facebook, twitter, LinkedIn,  instagram, and whatsApp utilize cloud components and  storage methodologies. Ø  E-mail sites that utilize cloud computing facilities  includes Gmail,Yahoo,Rediff,Hotmail etc. Ø  Search Engines like Google, Bing, Yahoo etc apply  cloud computing tools in their deployment. Ø  There are many more services over the internet that  either directly utilizes or receives adequate support from  cloud computing systems. Ø  Online sale marketing i.e Ecommerce websites  utilizing  Cloud Computing. Advantages: Ø Lower Computing Cost Ø Improved Performance Ø Reduced Software Cost Ø Instant Software Updates Ø Unlimited Storage Capacity Ø Increased Data Reliability Ø Device Independence and the “always on!, anywhere and any place” Ø Free From Maintenance and the “no-need-to-know” Disadvantages: Ø Requires a constant Internet connection. Ø Does not work well with low-speed connections. Ø Features might be limited. Ø Can be slow. Ø Stored data might not be secure. Ø Stored data can be lost.
