Potential benefits of Cloud Computing for end users
Lower computer costs.
A high-power computer is not needed to run cloud-based applications. Since applications run in the cloud, a desktop computer does not need the processing power or hard disk space demanded by traditional desktop software, or even a DVD drive.
With fewer programs using the computer’s memory at the same time, it will perform better. Desktop computers that use cloud-based services may boot and run faster because they have fewer programs and processes loaded into memory.
Reduced software costs.
Instead of purchasing software applications, cloud computing applications can often be obtained for free. An example is the Google Docs suite for consumers.
Instant software updates.
Updates to a cloud-based application generally occur automatically and are available on logging into the cloud. When accessing a web-based application, the latest version is usually instantly available, without need for an upgrade.
Improved document format compatibility.
All documents created by web-based applications can be read by any other user accessing that application. There are fewer format incompatibilities when all users are sharing documents and apps in the same cloud.
Unlimited storage capacity.
Cloud computing can offer virtually limitless storage. A computer's current hard drive space is small compared to the storage space available in the cloud. Note however that large scale storage is generally not available for free, even in a cloud environment.
Increased data reliability.
Unlike desktop computing, in which a hard disk crash can destroy personal data, a computer crashing in the cloud should not affect the storage of data, as typically cloud services provide multiple layers of security (see however Section 4.2 below for a discussion of data security in a cloud environment).
Universal document access.
Documents stay in the cloud, and can be accessed from wherever with an Internet-capable device and an Internet connection. Documents are instantly available independent of location, removing the need to carry them when travelling.
Latest version availability.
When editing a document from one location (e.g. at home), that edited version is identical to the document accessed from another location (e.g. at work).
Easier group collaboration.
Multiple users can collaborate easily on documents and projects. Because the documents are hosted in the cloud, not on individual computers, an Internet connection is all that is needed to collaborate.
When changing computers or moving to a portable device, existing applications are still available. There is no need for a special version of a program for a particular device, or to save a document in a device-specific format.

Far and away, the industry that pops up the most in discussions of big data is health care. It’s not surprising, if you think about it. Lots of disparate sources of data, much of it unstructured. An industry dying to become more cost-effective – or, at least, less wasteful. And an onslaught of new devices designed to automate the process of collecting data, on order to keep professionals from having to be on hand to do so.
After years of IT work to support major merger and acquisition (M&A) activity, global chemicals company Solvay is now focusing on innovation to drive more internal efficiency. The Belgium-based firm, which operates in 55 countries, saw its workforce double from 15,000 to 30,000 in 2011 after it acquired chemicals company Rhodia. As a result, Solvay had to make changes and improvements to its IT set-up.
Google launched a couple of updates to its cloud-based big data products at the Hadoop Summit in Brussels on 16 April. These included the launch of the open beta of Cloud Dataflow, Google’s new service for processing huge amounts of data, as well as an update to BigQuery, which will make the company’s bid data database service available in Google’s European data centers and introduces row-level permissions.
Today, it seems the cloud is the answer to every question. Where are my photographs? How does this app work? How will our management strategies change with the cloud? It wasn't always thus. So how did the cloud come to develop us all in its fluffy ubiquity? check IBM's inforgraphic.
Wehkamp needed to improve its online retail services and use big data and analytics to provide their mostly young customers with a personalised and tailored online shopping experience, as well as improve profitability. The results of using cloud services for digital analytics, customer experience management and email campaigning speak a language any shareholder can understand: a 271% higher sales-per-send ration for marketing emails, including a 68% higher click-through rate
Cloud computing is one of the strategic digital technologies considered important enablers for productivity and better services. The most substantial impact of cloud technology could come in the cost savings and increased competitiveness of IT services available to public and private organisations, as well as opportunities leading to new services, but cloud technology could positvely increase other benefits for end users.
- To move with the times, global engineering solution provider Costain needed to streamline existing construction processes and provide post-build maintenance and infrastructure management services.
- It worked with MobiCloud to build context-aware, cross-platform and cloud capabilities so it can take full advantage of mobile devices, increasing efficiency while reducing costs.
