Cloud computing systems have two ends - a front end consisting of user computers and clients that access applications, and a back end of servers, data storage, and computer programs in the "cloud" section. Users interface with the front end to send traffic and requests through the internet to the back end systems, which are operated from a single or multiple locations and monitored to ensure everything runs smoothly between the two connected ends.

Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive.In computer networking, cloud computing is a phrase used to describe a variety of computing concepts that involve a large number of computers connected through a real-time communication network such as the Internet.
Cloud computing is a type 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),

The term “Cloud Computing” is a recent buzzword in the IT world. Behind this fancy poetic phrase, there lies a true picture for the future of computing for both in technical prospective and social prospective. However, the term “Cloud Computing” is recent but the idea of centralizing computation and storage in distributed data centers maintained by third party companies is not new but it came in the way back in 1990s along with distributed computing approaches like grid computing. Cloud computing aimed at providing IT as a service to the cloud users on-demand basic with greater flexibility, availability, reliability and scalability with utility computing model. This new paradigm of computing has an immense potential in it to be use in the field of e-governance and in rural development perspective in the developing country like India.
A presentation on layered software architecture that goes through logical layering and physical layering, the difference between those two and a practical example.

This presentation I've made on Cloud computing can be used by students for their college projects. I've tried to make this as colourful and attractive as possible without losing the relevance with the topic.

Intro to cloud computing — MegaCOMM 2013, JerusalemReuven Lerner
What is cloud computing? This is an introduction that I gave at MegaCOMM 2013, a conference for technical writers in Jerusalem. The talk describes how the combination of Internet access, virtualization, and open source have made computing a utility that we can turn on and off at will -- similar in some ways to electricity, water, and other utilities with which we're familiar.
Symantec’s Avoiding the Hidden Costs of Cloud 2013 Survey found more than 90 percent of all organizations are at least discussing cloud, up from 75 percent a year ago. Other key survey findings showed enterprises and SMBs are experiencing escalating costs tied to rogue cloud use, complex backup and recovery, and inefficient cloud storage.
The 2013 Future of Cloud Computing 3rd Annual Survey was conducted in partnership with GigaOM Research and 57 industry collaborators. It focuses on Cloud adoption, growth, investment, and key trends emanating from the 2011 and 2012 surveys.

Can we hack open source #cloud platforms to help reduce emissions?Tom Raftery
Cloud computing is changing our lives but this change comes with a cost - pollution.
Can we hack open source cloud platforms to make them report their energy and (more importantly) their emissions, so we can choose the cleanest cloud?
Video of this talk is now online at http://redmonk.com/tv/2012/10/24/can-we-hack-open-source-cloud-platforms-to-help-reduce-emissions/
Public cloud's are going to crash. It's inevitable. The best thing you can do is be prepared with a highly available architecture to ensure you're not affected by the outage. Join a live webinar with Gigaspaces founder and CTO Nati Shalom to discuss best practices in high availability to safe guard your cloud from the inevitable outage.

Building cross-region and cross could high availability into your app, a real life use case by Gigaspaces, Nati Shalom, Funder & CTO, Gigaspaces
Achieving high levels of availability and disaster recovery in a cloud environment requires the implementation of patterns and practices that introduce redundancy through multi-zone, multi-region, and multi-cloud deployments. As we move towards implementing higher availability, we cannot escape the direct increase in the accidental complexity of the deployment architecture resulting from lack of cloud portability and deployment lifecycle automation. We present how high availability and disaster recovery were achieved in reality by using the Cloudify open source framework on top of AWS. This approach applies to not just AWS but also other public clouds and private cloud environments such as Eucalyptus. The resulting reference architecture provides portable PostgreSQL replication and disaster recovery as well as application tier scalability across zones, regions, and public/private clouds through a unified deployment workflow.
LinuxFest NW 2013: Hitchhiker's Guide to Open Source Cloud ComputingMark Hinkle
Presented on April 27th, 2013 at LinuxFest NW
Imagine it’s eight o’clock on a Thursday morning and you awake to see a bulldozer out your window ready to plow over your data center. Normally you may wish to consult the Encyclopedia Galáctica to discern the best course of action but your copy is likely out of date. And while the Hitchhiker’s Guide to the Galaxy (HHGTTG) is a wholly remarkable book it doesn’t cover the nuances of cloud computing. That’s why you need the Hitchhiker’s Guide to Cloud Computing (HHGTCC) or at least to attend this talk understand the state of open source cloud computing. Specifically this talk will cover infrastructure-as-a-service, platform-as-a-service and developments in big data and how to more effectively take advantage of these technologies using open source software. Technologies that will be covered in this talk include Apache CloudStack, Chef, CloudFoundry, NoSQL, OpenStack, Puppet and many more.
Specific topics for discussion will include:
Infrastructure-as-a-Service - The Systems Cloud - Get a comparision of the open source cloud platforms including OpenStack, Apache CloudStack, Eucalyptus, OpenNebula
Platform-as-a-Service - The Developers Cloud - Find out what tools are availble to build portable auto-scaling applications including CloudFoundry, OpenShift, Stackato and more.
Data-as-a-Service - The Analytics Cloud - Want to figure out the who, what , where , when and why of big data ? You get an overview of open source NoSQL databases and technologies like MapReduce to help crunch massive data sets in the cloud.
Finally you'll get a overview of the tools that can help you really take advantage of the cloud? Want to auto-scale virtual machiens to serve millions of web pages or want to automate the configuration of cloud computing environments. You'll learn how to combine these tools to provide continous deployment systems that will help you earn DevOps cred in any data center.
[Finally, for those of you that are Douglas Adams fans please accept the deepest apologies for bad analogies to the HHGTTG.]
The Total Cost of Ownership (TCO) of Web Applications in the AWS Cloud - Jine...Amazon Web Services
Weighing the financial considerations of owning and operating a data center facility versus employing a cloud infrastructure requires detailed and careful analysis. In practice, it is not as simple as just measuring potential hardware expense alongside utility pricing for compute and storage resources. The Total Cost of Ownership (TCO) is often the financial metric used to estimate and compare direct and indirect costs of a product or a service. Given the large differences between the two models, it is challenging to perform accurate apples-to-apples cost comparisons between on-premises data centers and cloud infrastructure that is offered as a service. In this presentation, we explain the economic benefits of deploying a web application in the Amazon Web Services (AWS) cloud over deploying an equivalent web application hosted in an on-premises data center and highlight the 5 things to not forget while calculating TCO.
