Cloud Computing Architecture and its future..

/ prabasiva / Leave a comment

Cloud computing concept continue to receive acceptance and its adaption increases exponentially.

I heard today from one of vendor representative that he grew up in the farm and growing up in the farm means he had to learn whatever required in no time to do farming. He confirmed my thoughts on how farm boys grow up in the farm. Cloud computing basically took the farm boy approach. Do whatever is required to do the job!

Fifteen years ago, the PC support team use to install the operating system (windows 3.11,MS-DOS ) in each and every PCs and PC support cost use to be a significant cost in the IT shop. As repetitive mundane tasks mandates  innovation, solution like Norton Ghost solution were emerged and hence deployment made easy and drove the PC support cost down.

Cloud computing took the Norton Ghost solution to the server environment.  Like me, I can imagine most of the IT members spent significant time in  building the development, testing, staging and production environment for each application and spent  time to ensure that all the environment were build alike and still had environment behaved differently for unknown reasons. Cloud computing solves all theses problems.

Key components of cloud computing:

Utilizing the external storage in the server environment has been in use for quite a while. In some cases, like manufacturing production databases, selecting the apt external storage platform including hardware, storage operating system, connectivity and raid types plays a vital role in the system architecture.  Likewise, in the cloud computing, the storage and processing unit are physically separated and logically connected as and when required. It includes the boot volume too.  To manage both processing units and storage units, an external operating system called cloud computing operating system is used. There are vendors like vmware sells cloud computing operating system like vmware vSphere and there are open source cloud computing operating system like eyeOS

  • Processing Units
  • Storage units
  • Cloud computing OS
  • Network units

Architecture of cloud computing:

For external users

Have a OC3 or OC12 or OC48 internet link based on your requirement to connect to the internet for your data center. Have a cisco 7200 series and cisco ACE series for your first and second layers of your network. Have netcahce or ssl accelerator or intrusion prevention devices based on your requirements. Connect the internal vlan with blade server (HP) and storage units like EMC. Slice the EMC luns to have a preload images like Redhat, Windows with preloaded system software like application server, web server, domain name server, database server, director server and etc. Install the cloud computing operating system in the external boxes and link both processing and storage units. The cloud computing operating system manages both processing and storage units.

If there are requirements to connect stand alone servers, it can be connected in the internal vlan.

The architecture is straight forward and purposefully I’m not drawing it.

For internal users:

The same architecture expect OC3 internet link.

Cloud Computing Future:

The concept is very cost effective and efficient. Instead of building images for production servers with application server, web server, database server and etc.. the image will be elevated to more business unit image. Loan processing image, collection and customer service image, delinquency image, skip tracing image,  bankruptcy, treasury, securitization, point of sale and etc.  The technology cloud is in the phase of reaching maturity and business cloud is emerging. There is a huge potential for the players who get quickly into the business cloud.

Think about for a minute, if you are bank, why do you want to spend time on building IT infrastructure to process loan. Banks JUST want to focus on getting good papers, good customers and not worry about how the assets are stored, retrieved and processed. Whoever get into business cloud will lead that market segment for a while!!


IT Waste Management..

hmm.. Do you know what is being wasted in your IT organization?

Nirvana (the highest level of maturity) is not reality in IT organization. It is a stretch goal. There are always room for improvement in any IT organization.

Some time back, a set of projects were perceived as a high business value projects and in last few months the business climate or economical climate might have changed and the project could be in the brink of extinction.

Some time back, a set of skills was perceived as a core competency for the future organization and due to the recent merger or acquisition or economical situation, the business strategy changed and hence the IT strategy. The core competency developed few years ago is not core any more in the current environment.

Some time back, a set of tools bought to enable efficiency with in the organization is not really working out due to various reasons..

What ever the situations may be, the past investment made in technology, people, process may not be currently required with in the organization.

IT Waste Management must be part of IT finance management group and IT finance manager/director is responsible for IT waste management function.

IT Waste Management Process:

Trigger:
Change in business strategy, IT strategy,executive leadership (end up by changing the IT strategy) or  merger, acquisition

  1. Clearly understand the current direction of company
  2. Clearly understand the change in direction due to the trigger
  3. Identify the gaps
  4. Assess the impact of directional change in terms of
    • Vendor Contract  – Hardware/software/Purchase service/Professional service
    • Intellectual  capital loss (work with HR and IT senior management )
    • System landscape  (work with Architecture team)
  5. Identify the retirement plan or reusable plan for all IT assets. Multiple teams like architecture, HR, procurement all need to work together to develop the above plans.
  6. Execute the plan. Realize and monitor the benefits
  7. Report the sun downed systems to IT controlling as IT impairment assessment. The IT intangible assets which are in the books can be adjusted and would bring tax benefits to the company.

The systems which are sun downed or retired in the process must be reported to IT controlling as a IT asset impairment assessment to reflect the new IT intangible asset value in the books. It would bring tax saving to the company.

The above steps are part of IT waste management process and must be performed every 3-6 months in every IT organization.  It will bring operational and cost efficiency to any IT organization.

IT Finance Management Framework – Part 2

/ prabasiva / 2 Comments

Understanding how the IT budget process fit into the overall corporate finance is essential to grasp the big picture.  The following figure illustrates how the IT G&A operating budget fits into the over all corporate finance.

IT organization must decide the technique suitable for the budget cycle. To select the best suited techniques the organization must make them self familiar with the available options. Let me list the various widely used technique available to create the IT G&A operating budget.

  • Static Budget – Presents one forecast for a given time frame and does not change for budget cycle
  • Flexible Budget – Budgeted Revenue and cost are adjusted during the budget cycle
  • Incremental budget – Previous year actual are taken as the base line and added or deleted additional cost for current year
  • Zero Based budget – Begins from ground up
  • Top Down budget – Each directors are given a budget task to align to CIO budget target
  • Participatory Budget – Developed as a collaboration with all directors (generally very difficult to make it practical)

There are other budgeting technique like activity based budgeting, Kaizen budgeting and etc. Kaizen  is a type of incremental budget with cost effectiveness target are given to each directors. To make the framework complete, I understand the widely used budgeting technique must be captured and it will eventually.

For this version 0.1, I want to start with zero based budget since I like the concept. It is very practical and gives an opportunity to each director or even senior manager or manager level to challenge every activities and look for some level of business case. Zero based technique can be used if it is top down budget and budget task are given by CIO to each director. Let me start with ZBB.

Zero based budgeting must be done in the manager or team leader level and rolled up to director and CIO level.  It requires the manager or team lead to understand the business and forecast the work required to keep the systems lights on, enhancements and G&A project.

The cost for lights on, enhancement and projects are will be incurred by employee, contractor, purchase servie, software cost & hardware cost. Each manager or team lead under each director will forcast for lights on, enhancement and project in terms of employee, contractor, purchase service, software cost and hardware cost.

The training required to perform the forecast will be the starting session of next part of this initial IT Financial Framework.
