IT as a Service, what does this mean?

IT as a Service means exactly, technology offered and served as a service. Pay for the technology we use, when we need it and to use only the technologies that we need.

It is something that entails a great revolution in the current IT service delivery and the IT world.

What is behind all of this? Since the marketing of so-called mainframe systems to the development of the personal computer arrived at the beginning of the twenty-first century, everything would become centred on a new concept: the internet, the network of networks and on developing web technologies, where information is no longer stored on a physical server of a local network but rather it has gone to a “sky” which is always connected and which lets us access it from any point on the network with only a browser and access to this network.

Now a new series of developed concepts are appearing from virtualization to cloud computing. These technologies want to change the technological world established by the era of the internet and transport us to a new revolution called “as a Service”. The information here floats on a cloud independently from where it is located and it can be used however needed and like a service.

Cloud computing is nothing more than a use and delivery of resources and services from the web model. A model where everything directs the “delivery” like “as a Service”, where it does not matter where the resources are located nor who provides them, but rather that they are always available, they are cheap, flexible, scalable, safe… and above all, they give me access to the information I need at any given time and from any device without needing extensive knowledge about computers.

It would basically changes the four models:

  • Purchase model: purchasing assets and creating architectures, versus purchasing services with pre-established architectures.
  • Business model: pay for fixed assets and administrative resources, against paying for the use we make of the technology
  • Access model: go from access thr  ough the corporate network and our desktop, against access via the internet and any device.
  • Technical model: Platforms which are rigid in terms of ownership, with maintenance and management costs, dependant on manufacturers and not used to 100% of their capacity, against multi-technological elastic platforms, self-managed and always made to fit the precise need in each moment.

It would be like being able to convert all the fixed costs from before to variable costs and pay per use.

This will allow us to improve our cash flow, reduce costs, help us to grow, reduce the time to market, make a sustainability Strategy and externalise technological management. This will allow us to focus solely on the necessary use of technology which applies to our business.

It would seem that we are on an irreversible road towards this world of distributed and customised computing…

    One needs to take into account the risks and tradeoffs for their particular application. The cloud may not be appropriate for certain environments, particularly those that require high data integrity and confidentiality. Some questions to ask? Where is the data stored? How is it stored and backed up (encrypted vs unencrypted). Who may have access to it? What happens and who is responsible should data get out in an unauthorized way? What are the penalties to the firm should data be compromised? Anytime you outsource your services you could be at risk of losing more control of your processes or product.

    Hi Ken,

    Thank you for your comment.

    100% Agree about the concerns as “consumerized cloud services” don’t seem to address properly data protection and integrity, latency is also an issue, here is where Hybrid Platforms come into place as not every Application is ready to sit in the cloud.

    Services with real-time transactions or driving plant operations need to be hosted close to the Field Devices inside Plant DMZ, other systems don’t, though the Public Cloud may not be yet feasible for them due to security policies…. there are “premium” so called cloud-services offering unparalleled availability and reliability, so clients pay storage and computing resources, or software-usage, on pay per use basis and knowing exactly where the data is hosted and who has access to it..

    Pushing services to the cloud is in every CIO strategy, knowing what service is suitable to be outsourced and building strong hybrid platforms are key factors to succeed.

    By the way, did you know Schneider Electric “IT Consulting & Integration Services runs” a Fort-Knox-like state of the art Infrastructure as a Service Platform that can integrate under one single support model: legacy, Virtual and Public Cloud Services? This service is called “The Global Cloud” and hosts both mission critical B2B and BC2 platforms and sensitive data under strict data protection act.
