Why every IT architect should understand something about CICS

Sometimes you stumble across a topic or some documentation that's just too good not to post about (Is that a correct English sentence ?). Even if it has already been brought to your attention through several other resources. So, I read about the new 'Architect's Guide to IBM CICS on System z' in the new CICS Portfolio eNewsFlash which you can find over here. And there were also some links to some other sources about it. So, instead of writing my own post about it, I'm going to do a bit of stealing (yes, even my post title) and I'll give you the references.

Bottom line is : every IT architect should know about the value of CICS. That's why Martin Keen starts his post on the IBM Software blog like this :
How many times did you use CICS Transaction Server this year? This week? Today? Unless you're already familiar with IBM's 43 year-old transaction server, you might be scratching your head and thinking “I've never used it!”.

Think again.

Have you had lunch yet? If so, did you pay with a debit or credit card? Then you've used CICS. Did you pay for lunch with cash instead? CICS entered your life then too – when you went to the ATM to withdraw the money.

And you're not alone. CICS Transaction Server handles a dizzying number of transactions every day. More than 30 billion transactions a day in fact(...)
Go on over there and read about the value of CICS and why every IT architect should know about it.

The same introduction to the Redbook is found on Youtube.

Still not convinced ? Then take a look over here to find out what inspired the writers of the Redbook.

But of course, do go and read the 'Architect's Guide to IBM CICS on System z' over here. And don't think : 'Oh, it's definitely beginner's stuff' because Martin Keen concludes :This is an essential book for architects, and a lot of other people besides. Even people who consider themselves CICS experts will learn something from reading it. I highly recommend it".

Still not enough ? Here's another 10-pager on the 'CICS Transaction Server Application Architecture'.

So, as I always say, do check them out !
