SOA filling the Gaps

     I was a Junior IBM Mainframe COBOL Programmer in the beginning of the 1970's.  IBM 360 computers was the leading platform with SVS Operating System and afterward MVS Operating System. IBM Mainframe platform was a leading platform in the decade before I started my computers career. My roles were changed to a System Programmer, a Manager, a Consultant etc.  I worked on many other platforms and on multiple platforms environments. The IT industry was also changed and the IBM Mainframe was no longer the leading platform. However, unlike other proprietary platforms it survived.  Nine years ago I wrote a post about a new Mainframe released. The post was titled:  IBM z-Enterprise First Take: Data Center in a Box or Cloud Computing . IBM Mainframe was still a viable platform for large Enterprises. It should be noted that Public Cloud implementation replacing Core Mainframe systems by Linux and/or Windows based systems is not yet a vi...

Many large banks are IBM Mainframes users. They use mainframes for decades. They use other platforms as well, but their Core Banking systems are deployed on Mainframes. Recently leading Cloud Computing vendors such as Amazon , Microsoft and Google approached large banks in order to start migration of systems to their Public Clouds.  I looked for evidence supporting the notion that Banks are transforming from Mainframes to Public Clouds. I found no evidence. I am not the one to be blamed for not finding any significant evidence, because there is no evidence supporting the notion cited above.  Banks are using Public Clouds but... Like many other organizations, banks are using Public Clouds applications. However, they do not use it for Core Banking systems deployment. They use Public Clouds for applications which are less integrated with the Core Banking systems. If they will not use Public Clouds for Core Systems, IBM Mainframes will be used for many years. Public...

The Public Cloud is a promise. A promise for a new model without an Information Technology department.  Unlike the Public Cloud, the Private Cloud is nothing to write home about. Utility Computing disguised in modern and attractive name.  Reality is not as simple as described in the paragraphs above.  If you read the article Tectonic shift as Public Cloud giants acknowledge the private deployment options , you will discover that even Amazon and Google admit that Public Cloud is not a magical solution for all problems. There is a necessity for Private Clouds. There are systems for which Public Cloud is not adequate.  Private Cloud It is relatively easy to define Public Cloud. There are various different definitions of Private Cloud.  The main definitions could be categorized as follows: 1. Cloud which is located within the Enterprise boundaries.  Utility Computing may fit to this definition. If the organization provides Information Technol...
