Public vs Private Clouds – Some History, Issues &  Recent Trends

Public Clouds

Cloud Computing was brought to masses by the public cloud companies like Amazon and Google. They helped the imagination of masses run wild with an attractive utility based pricing model and an ability to scale infinitely (albeit, theoretically) to meet any demand.

One of the major benefits of Cloud Computing is the utility base pricing model (pay for what you use) and bringing in an outside vendor into picture for offering the services; and on-demand use of resources. The single most defining element in the definition of Cloud Computing is the enormous cost savings in OpEx and the zero CapEx.

Enterprises started saying “yes, we can” to the idea of cloud computing. They saw the advantage of Cloud based technologies and wanted to adapt these technologies in their infrastructure. Seeing this trend, the reluctant ones like IBM and others jumped in. As we started digging in deeply about applying the idea of Clouds in a wider enterprise context, we understood that there were many needs and issues that were not obvious earlier. Everything from security to regulation to the need for better infrastructure to even the need to have some fine grained control. These issues became important and needed further understanding.

Private Clouds

The surging forward of public clouds and the initial debunking of the idea by enterprises and vendors like IBM, led to the development of Private Clouds. Private Clouds also grew in popularity out of the fear that Public Clouds needed to be made more secure especially in the enterprise realm and that public clouds failed to meet the regulatory requirements in certain countries.  A number of CTOs and CIOs, were afraid about putting their crucial business data in the hands of third parties; and how it was difficult to customize the public cloud infrastructure to meet their requirements and how the public clouds are too restrictive in this regard. There are many such issues that ensures that the idea of private clouds is relevant and, in fact, important and that segment began to grow.

The supporters of private clouds argue that it is not necessary to bring in the financial component and they see it as an evolution of already existing technologies including virtualization. They see it from a technology perspective and, also, as an operational model. A new way to deliver computing resources to either users inside the enterprises or to consumers like a public utility service provider.

Private and Public Clouds – Some Issues

The cloud is poised for considerable growth, but customers worry about how their data is stored. Who might have access to it, and can it be read while it is in transit?

The issues with cloud computing at this point include security, performance, costs, service and vendor viability. Security will be a leading concern for the foreseeable future,

While I believe in the eventual future of having all the computing resources on public clouds, expecting everyone to jump straight into the existing public cloud infrastructure is totally naive. It will take a long time before the complete transition takes place. The technology behind the cloud is still at a nascent stage, but it will evolve. The idea of security in the cloud needs some revamp and new approaches are needed to drastically improve the cloud security. There is not a worldwide consensus on the regulatory requirements on data security, privacy, customization needs and local requirements of customers from many different parts of the world.

These issues are a barrier to large scale adoption of public clouds in the near future. Even if people adapt to public clouds to achieve the economic benefit of the utility base pricing model (pay for what you use), there will definitely be users who embrace private clouds as they may need to have direct control over issues surrounding regulatory requirements, data security, privacy or local customization needs.

But Amazon, and other industry players that have a stake in the public cloud are determined that at least from a security perspective to make the Public Cloud more secure

For users who have adopted the Amazon Elastic Compute Cloud (EC2), the cloud has just gotten a little safer. Amazon has developed two significant features to ease security concerns, targeting the enterprise market. – Related Article : Private Clouds & Amazon.

These new features from Amazon while a good beginning have not yet solved all of the issues surrounding regulatory requirements, data security, privacy or local customization issues, but is an indication that both Amazon, and other players that have a stake in developing the Public Cloud are investing heavily to bridge the issue gap that currently exists between Private and Public Clouds.

Amazon and other leading industry players will continued to develop solutions that further resolve issues that previously prevented organizations to embrace the cloud. These product developments will make the differentiation between the public cloud and private clouds much smaller that will clear the way for all of us to move into public clouds in one form or another leading to the eventual future of having the majority of the computing resources on public clouds over the next decade.
