Multi-Tenancy Data issues

The Multi-Tenant model for SaaS look like an efficient and simple model. However, it is so simple on the abstraction layer. Complexities are hidden in more technical layers. Separating users data and data growth are two of the main issues. I recommend reading an interesting blog post written by Nati Shalom, describing clearly those issues and current approaches for handling the problems.

The mainframe: still alive and kicking

Recently, I was interviewed by Pcon (unfortunately the link points to an Hebrew only site) as part of debriefing on Legacy Systems. Pcon is an Israeli company investigating IT topics by quoting professional articles and interviewing experts. They publish the results of the investigations including practical recommendations. This post is mainly about topics raised by me during the interview, but not included in the debriefing, which will be published. What are Legacy Systems? The term Legacy Systems refers to old application systems and/or veteran technologies still in use. Usually, the term Legacy Systems is associated with: 1. Mainframe Hardware e.g. IBM System z and its Operating Systems or Proprietary Servers and Operating Systems such as HP Alpha and OpenVMS Operating System, IBM AS/400 and OS/400 Operating System. 2.

Will Business and IT Aligned?

For decades we are talking about closing the gap between business and IT , but the gap is still as wide as it was. In the beginning of the ERP era, we focused on aligning Business Processes and Core Systems, but in most enterprises we failed.

I do not know, but Nick Heath's article titled: Stop doing what the vendors tell you, CIOs told , published in Tech Republic , suggests that the root of the problem is not Technological . Stop Doing What the vendors Tell You Nick Heath's article is based ...

Vendors Survival: Will Software AG Survive until 2019?

This post is another post in the Vendors Survival series following posts on Microsoft , Google , HP , Sun and EMC . On July 14 th Software AG and IDS Scheer announced that Software AG is going to take over IDS Scheer . The intended acquisition is an opportunity to add another post in my Vendors Survival posts series. A brief history of Software AG Mainframe products Software AG is larger than any German software company except SAP . It was established in the Mainframe age (in 1969). I worked with many customers, who used and some of them are still using, its two flagship products Adabas and Natural . Although these products support many platforms, their main platform is IBM Mainframe. Adabas is a database and Natural is a development environment. Like other pairs of Database and Development Environment in the mainframe environment (e.g. Ideal and Datacom , Mantis and Supra) build by the same vendor, they are tied together. As a result, although it is possible t...
