Summary
One of the most talked about topics today is Cloud Computing – the new phenomenon set to change the way we use computers forever. Cloud computing refers to the delivery of software and other technology services over the Internet by a service provider and has been widely acknowledged as a viable way to reduce capital expenditures and operational costs. Although many companies have embraced this technology, some are unwilling to switch from internally owned and managed IT systems to cloud computing technologies due to fears of security threats and loss of control over company systems and data.

With its growing popularity, a large number of firms have started providing this service. We tried to compare some of these offerings on various parameters like infrastructure, data storage system, supported applications/frameworks, scalability, security etc.

The worldwide market for cloud services is expected to grow from $46.4 billion in 2008 to reach $150.1 billion in 2013 with a CAGR of 26.5%. Among the various cloud services, business process services alone have contributed 84% of the total revenue generated in 2008.

In this report, we mention some of the industry segments which have successfully utilized cloud computing. We also take a brief look into how some of the photo-sharing websites like SmugMug are using cloud computing.

Overview

• Cloud computing is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet.
• Users need not have knowledge of, expertise in, or control over the technology infrastructure in the "cloud" that supports them.
• Cloud computing services often provide common business applications online that are accessed from a web browser, while the software and data are stored on the servers.

The concept generally incorporates combinations of the following:

Three major participants in cloud:

1. Cloud Providers; building out clouds, for instance Google, Amazon, etc. effectively technology providers.
2. Cloud Adopters / Developers; those developing services over the Cloud and some becoming the first generation of Cloud ISVs.
3. Cloud "End" Users; those using Cloud provisioned services, often without knowing that they are cloud provisioned, e.g. Facebook users have no idea that their favorite FB app is running on AWS.

Various architectural layers:

1. Operations: it supports functional business processes rather than supporting the technology itself.
2. Service layer: it is made up of application code, bespoke code, high-level ISV offerings.
3. Platform layer: it is made up of standard platform software i.e. app. servers, DB servers, web servers, etc., and an example implementation would be a LAMP stack.
4. Infrastructure layer: it is made up of

(i) infrastructure software (i.e.virtualisation and OS software)

(ii) the hardware platform and server infrastructure

(iii) the storage platform

1. Network layer: it is made up of routers, firewalls, gateways, and other network technology.

Delta of Effort / Delta of Opportunity

The gap between the cloud providers and the end cloud users is known as the delta of effort and also the delta of opportunity.

It is the delta of effort in terms of skills, abilities, experience and technology that the cloud adopter needs to deliver a functional service to their own “End Users”. This will be potentially a major area of cost to the cloud adopters. But it's also the delta of opportunity in terms of 'room' to innovate.

Cloud computing applications in different industry segments

Pharmaceutical

• Historically, most large pharmaceutical firms have run fully integrated vertical business models, doing all they can in-house and choosing to selectively outsource where appropriate

• Firms now seek to reduce the time and cost through sharing an integrated platform which is cheaper, less time consuming, and more supportive of a networked business model

• Pharma companies exploring cloud computing have reported positive experiences through

• Easier implementation
• More computational transparency
• A clear-cut IP policy
• Scalable invoicing

Pfizer

• Protein engineers and informaticians at Pfizer’s Biotherapeutics and Bioinnovation Center faced the challenging task of antibody docking that presented enormous computational roadblocks.
• Each antibody model requires the respectable models of the protein’s three-dimensional structure to be generated on Rosetta++ platform which carries out refinement of antibody docking.
• Refinement involves small local perturbations around the binding site followed by evaluation with Rosetta’s energy function – an iterative process using 200-nodes cluster that requires a massive amount of computing.
• An array of Rosetta workers are spun up on Amazon’s EC2. The S3 stores inputs and outputs, SimpleDB tracks job meta-data, and the Simple Queue Service glues it all together with message passing and the entire process is completed overnight which previously took months.
• Consequently, the research staff is focusing more on results without pushing their projects on back-shelf.

Eli Lilly

• Eli Lilly is using cloud computing services to support scientists with on-demand processing power and storage.
• The firm uses Amazon Web Services and other cloud services to provide high-performance computing, as needed, to hundreds of its scientists.
• Eli Lilly foresees the possibility of using cloud services from a half dozen different vendors and need for an “orchestration layer” that sits between Eli Lilly and the various cloud services.
• It would comprise algorithms that determine the best cloud service for a particular job based on lowest cost, highest performance, or other requirement. Such an approach would make it possible for Eli Lilly and other users to write to a single API rather than many, while optimizing service usage.
• The firm is also exploring the potential to use cloud computing for external collaboration between Eli Lilly and outside researchers.

Johnson and Johnson

• Johnson and Johnson is seeking to complement its high performance grid architecture with cloud computing, mainly in the area of drug discovery modeling applications, according to Rick Franckowiak, director for systems engineering at the Pharmaceutical Research & Development IT organization at Johnson & Johnson.
• Require enhanced computing and storage capabilities and address spike-type processing demand.
