The Open Cloud Manifesto

Extracts from the Open Cloud Manifesto

The buzz around cloud computing has reached a fever pitch. Some believe it is a disruptive trend representing the next stage in the evolution of the Internet. Others believe it is hype, as it uses long established computing technologies. As with any new trend in the IT world, organisations must figure out the benefits and risks of cloud computing and the best way to use this technology.

What is Cloud Computing and Why is it Important?

In order to understand the core principles of an open cloud, we need to first agree on some basic definitions and concepts of cloud computing itself. First, what is the cloud? The architecture and terminology of cloud computing is as clearly and precisely defined as, well, a cloud. Since cloud computing is really a culmination of many technologies such as grid computing, utility computing, SOA, Web 2.0, and other technologies, a precise definition is often debated.

The key characteristics of the cloud are:

  • Scalability on Demand
  • Streamlining the data Centre
  • Improving Business Processes
  • Minimising Startup Costs

Challenges and Barriers to Adoption

Although the cloud presents tremendous opportunity and value for organisations, the usual IT requirements (security, integration, and so forth) still apply. In addition, some new issues come about because of the multi-tenant nature (information from multiple companies may reside on the same physical hardware) of cloud computing, the merger of applications and data, and the fact that a company’s workloads might reside outside of their physical on-premise datacenter.

  • Data and Application Interoperability
  • data and Application Portability
  • Governance and Management
  • Metering and Monitering

The Goals of an Open Cloud

Customers expect that the cloud services they use will be as open as the rest of their IT choices. As an open cloud becomes a reality, business leaders will benefit in several ways.

  • Choice
  • Flexibility
  • Speed and Agility
  • Skills

Principles of the Open Cloud

Many clouds will continue to be different in a number of important ways, providing unique value for organisations. As cloud computing matures, there are several key principles that must be followed to ensure the cloud is open and delivers the choice, flexibility and agility organisations demand:

  1. Cloud providers must work together to ensure that the challenges to cloud adoption (security, integration, portability, interoperability, governance/management, metering/monitoring) are addressed.
  2. Cloud providers must not use their market position to lock customers into their particular platforms and limit their choice of providers.
  3. Cloud providers must use and adopt existing standards wherever appropriate.
  4. When new standards (or adjustments to existing standards) are needed, we must be judicious and pragmatic to avoid creating too many standards.
  5. Any community effort around the open cloud should be driven by customer needs, not merely the technical needs of cloud providers, and should be tested or verified against real customer requirements.
  6. Cloud computing standards organisations, advocacy groups, and communities should work together and stay coordinated, making sure that efforts do not conflict or overlap.

Conclusion

Although this is a time of great innovation for the cloud computing community, that innovation should be guided by the principles of openness. Industry participants must work together to ensure that the cloud remains as open as all other IT technologies.

Future Directions for Rich Internet Applications

Thursday, 19th July 2007 in Strategy, Technology by Simon | 2 comments

Rich Internet Applications (RIAs) are just the beginning. A key trend taking place throughout the Web industry is the urgency to integrate disparate systems and software tools to reduce costs, increase developer productivity, reduce the need for manual processing and intervention in transactions, and decrease time to market. To achieve these objectives, organisations have endorsed the adoption of standards-based systems (e.g. XML, Design Patterns, CSS, ECMAScript) combined with the migration to Web Services and Service Orientated Architecture (SOA). This has led to a requirement to create a consistent and intuitive interface to applications, data and services. The immediate goal of these efforts is to provide simpler, quicker and more efficient access and processing of information. Increasingly, Web applications are also offering customers application interfaces that are more personalised and customised to each individual’s specific requests and requirements.

It is clear that RIAs offer the potential to fundamentally change the user experience and in doing so, yield significant business benefits. However, in order for RIAs to be widely employed, and for more companies to receive these kinds of returns, technologies to build RIAs will need to appeal to a wider range of developers. The ability to cost effectively create rich, engaging user experiences that support corporate objectives and reach a broader developer audience without sacrificing development productivity require a new generation of RIA tools. These tools are being developed by a large number of organisations with Adobe, Microsoft, Google, Apple and Sun leading the way with the AIR/Flash/Flex combination, Silverlight, Gears, Quicktime and JavaFX respectively.

The new generation of RIA tools being developed by the likes of Adobe and Microsoft must do the following to allow developers to truely harness the power of RIAs in the commercial environment:

  1. Allow developers to write applications using familiar development models to utilise and extend their current skills without requiring them to adopt entirely new or different skills
  2. Use standard and standards-based technologies
  3. Use industry specific programming models and patterns
  4. Use and/or leverage the existing IT infrastructure through wrap and reuse rather than rip and replace
  5. Provide pervasive, familiar programming models and an expressive user interface across platforms and devices; and
  6. Allow developers to create a solution that delivers scalable, secure, high performance solutions that are bandwidth efficient

These new RIA tools will need to provide the features that enhance IT developer’s abilities to be more creative and to accomplish RIA development with the same or less effort than the tools they use to create other types of applications. What is required are the tools that can help developers achieve these objectives without relying on only HTML or other scripting languages, or having to learn a completely new development approach.

Two vendors which have the technology and capaibility to fully deliver Rich Internet Applications are Adobe and Microsoft. With Microsoft’s Silverlight and XAML, developing rich internet applications to run on Windows platforms will progress at a fast rate. In turn, Adobe has had a head start with the aquisition of Macromedia and the subsequent addition of Flash and Flex to its product offering. Flash and its relative ubiquity across platforms and devices ensures that RIA development and production will be accessible to a large user base and as such puts Adobe at a distinct advantage over Microsoft.
