A Vision – The Key To a Cloud Computing Strategy

Look out!

The marketing and hype around Cloud Computing could cloud your mind 😉

Just building a Cloud doesn’t imply successful business. First of all you need a clear vision on how Cloud Computing can enable or improve your business. This vision will enable you to found a solid Cloud Computing strategy. And with this strategy you’ll “go cloud” successfully. Sounds straightforward, but it isn’t. You need to consider several key issues:

  • Good understanding of IT service – offering Cloud services involves building a service portfolio and defining service-level-agreements (SLA) for example.
  • Market analysis – is there a real need of your Cloud services?
  • Competitor analysis – are you competing against similar Cloud services?
  • Business case analysis – how is the ratio of the profit (or loss) relative to the cost basis resp. the return on invest (ROI)?
  • Steady benchmarking tests – or: continuous competitor analysis

Especially in case of Cloud Computing it is mandatory to tightly align business and IT because IT executes the business strategy, or more specifically, when delivering Cloud services to users/customers IT is acting as a business for itself with something to sell – that is the Cloud services.

To conlude, building a Cloud implies previous realignment of the business structure. With this concluding words I go into the weekend.

Bye for now!


Cloud Computing – Evolutionary Step to Support Changing Business Needs

Hello, I’m back again 🙂

with this post I start a blog series about Cloud computing with the objective of promoting the next evolutionary step in the history of Information Technology.

While the Cloud hype might be annoying at first sight, it indicates on the other hand the dimension and importance of the underlying fundamental challenge: IT is evolving in order to support the changing business needs. Cloud computing is agile computing. And agility of IT enables organizations to be leaders in global economy. From the very high level perspective, Cloud computing is nothing more than about sharing IT infrastructure and managing application workloads in a highly efficient manner.

Among the variety of Cloud computing definitions the National Institute of Standards definition is gaining more and more popularity:

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.

This model is composed of five essential characteristics, three service models, and 4 deployment models.

Cloud computing characteristics:

  • On-demand self-service
  • Resource pooling
  • Rapid elasticity
  • Measured service
  • Broad network access

Cloud computing service models (XaaS):

  • Saas – Software-as-a-Service
  • PaaS – Platform-as-a-Service
  • IaaS – Infrastructure-as-a-Service

Cloud computing deployment models:

  • Public Cloud
  • Private Cloud
  • Community Cloud
  • Hybrid Cloud

I think, no, I hope that the Cloud hype will reach its zenith during this year. Before Cloud computing finally enters the stage of pure productivity we will, sad to say, experience prestages like the burst of the wishful-thinking-bubble, followed by the “Trail of Tears”, and then the “Age of Enlightenment”. At the end of day, when Cloud computing has passed all these stages, it will be no longer cool meaning that it will be a mature computing model that just simply works – just like virtualization nowadays. By the way, do you remember the virtualization hype a few years ago…?

So, there’s absolutely no rush to switch to Cloud computing as soon as possible. Many companies are building cloud services today and some are more successful than others. Do you know what I mean? While some companies just try to “go cloud” and fail, others evolve a Cloud computing vision for their business first – a vision that uses Cloud computing as an enabler.

That’s it for now. Next time, I will enter into this epilogue.
