rPath's take on Cloud Computing: Pragmatic Cloud Adoption

A Pragmatic, Incremental Approach to Cloud Computing

Cloud computing holds real promise for enterprises and SMBs, as well as the ISVs and individual developers serving them. Among other benefits, cloud computing can help organizations:

* reduce capital and operating expenses by increasing infrastructure utilization and reducing server sprawl.
* reduce the cost of software consumption by allowing business lines to consume application functionality on demand and to align cost with value received.
* dramatically improve business agility and responsiveness by compressing deployment cycles and time-to-value for application functionality.

To help organizations realize the promise and avoid the perils of cloud computing, the Cloud Computing Adoption Model provides a pragmatic, actionable, step-by-step framework for achieving measurable benefits now, while laying the foundation for the strategic benefits of a cloud infrastructure over time. The five levels of cloud computing adoption include:

* Level 1: Virtualization. The first level of cloud adoption employs hypervisor-based infrastructure and application virtualization technologies for seamless portability of applications and shared server infrastructure.
* Level 2: Cloud Experimentation. Virtualization is taken to a cloud model, either internally or externally, based on controlled and bounded deployments utilizing Amazon Elastic Compute Cloud (EC2) for compute capacity and as the reference architecture.
* Level 3: Cloud Foundations. Governance, controls, procedures, policies, and best practices begin to form around the development and deployment of cloud applications. Initially, level 3 efforts will focus on internal, non-mission critical applications.
* Level 4: Cloud Advancement. Governance foundations allow organizations to scale up the volume of cloud applications through broad-based deployments in the cloud.
* Level 5: Cloud Actualization. Dynamic workload balancing across multiple utility clouds. Applications are distributed based on cloud capacity, cost, proximity to user, and other criteria.

For each level, The Cloud Computing Adoption Model outlines strategic goals, investment requirements, expected returns, risk factors, and readiness criteria for advancement.

Avastu Blog is migrating to IdeationCloud.com; 1st Jan 2009 live

YOU DON'T HAVE TO DO ANYTHING. WITHIN 2 SECONDS YOU WILL BE REDIRECTED TO THE NEW HOME OF AVASTU BLOG. PLEASE DO UPDATE AVASTU BLOG'S URL to : http://www.ideationcloud.com on your website.

I will send out emails personally to those who are using my link(s) on their sites.

Thanks much for your co-operation and hope you enjoy the new site and its cool new features :-)




Not like the site is unlive or something..on the contrary, its beginning to get a lot of attention already. Well most of the work is done, you don't have to worry about anything though:

What won't change

Links/Referrals: I will be redirecting the links (all links which you may have cross-posted) to IdeationCloud.com - so you don't have to do anything in all your posts and links. Although, I would urge however that you do change the permalinks, especially on your blogs etc yourselfThis blog is not going away anywhere but within a few months, I will consider discontinuing its usage. I won't obviously do …

Cloud Security: Eliminate humans from the "Information Supply Chain on the Web"

My upcoming article, part - 3 data center predictions for 2009, has a slideshot talking about the transition from the current age to the cloud computing age to eventually the ideation age- the age where you will have clouds that will emote but they will have no internal employees.

Biggest management disasters occur because internal folks are making a mess of the playground.

Om's blog is carrying an article about Cloud security and it is rather direct but also makes a lot of sense:

I don’t believe that clouds themselves will cause the security breaches and data theft they anticipate; in many ways, clouds will result in better security. Here’s why: Fewer humans –Most computer breaches are the result of human error; only 20-40 percent stem from technical malfunctions. Cloud operators that want to be profitable take humans out of the loop whenever possible.Better tools – Clouds can afford high-end data protection and security monitoring tools, as well as the experts to run them. I trust…
