Having got my latest rant off my chest in the previous entry I would like to return to the whole area of cloud / dynamic computing.
In an earlier entry, what I threw open to debate was how do you set, measure and report SLAs in a cloud environment? Who owns the service? Who reports to whom? Who knows how to react to a problem? Is it critical to them as a provider or critical to you as their customer? What does an outsourcing contract look like in a "Cloud" world"? etc. etc.
What's going round my brain at the moment is taking this further into the whole world of dynamic computing, where everything is in a constant state of change. One of the key components in a BSM world is the CMDB, which is difficult enough to populate in a static environment. How is discovery going to work in a dynamic environment? How rapidly is it going to discover and react to the change? Is discovery going to be tied into change and compliance management so that changes, which do not fit the (hopefully established) business policies are rejected? etc. etc.
I would be very interested in your thoughts or any experiences anyone would like to share on managing a dynamic environment.
cloud computing services helps me in keeping my e-books safely in my Audible library,my writing lives in Wordpress, video clips are on Vimeo and photos are on Photobucket. Appsummary.com is a leading organization in the field of providing services of web app reviews at very affordable price.It has a great specialization in cloud reviews .It has dedicated and highly skilled reviewers.thanx for sharing your piece of information,,,,,
Yep, I do similar things - flickr for photos, kindle for books etc.
Several comments:
1.As an old mainframe person I would argue that I did cloud computing 30 years ago via a dumb terminal into a mainframe - using things like TSO, CICS, IMS etc. My data was in a "cloud" and I could access it from anywhere. Only with the advent of the supposedly wonderful PC, did we all get in the habit of sticking data on our own workstations (if a train station is where the train stops, what is a workstation?)
2. As I used to travel the world with my PC I frequently asked myself why I was carting a screen, a keyboard etc. round with me - all I needed was access to my data. Now I can do most of my work from an internet connected terminal anywhere in the world - hey presto we are back to the dumb terminal attached to a collection of servers.
3.Where I was going with this entry is the back end, where the apps and data live, and in a corporate environment these apps and data may well reside in multiple locations, with multiple companies providing parts of the business services. How do you manage SLAs across that?
Cheers
