The DB2 landscape is changing quickly, and sometimes things can quietly sneak in before you even realize it. Maybe you have heard IBMers talking about JSON support in DB2, but have you heard about the mobile DB2 access and DB2 RESTful API that is now available for DB2 for z/OS?
DB2 has several new Cloud offerings. With DB2, you can get support for OLTP or Analytics. The database can be hosted or fully managed. This presentation by Kelly Schlamb at the 2015 IDUG Tech Conference in Australia details the three products, their differences and the use cases for each.
The video below is a presentation recorded at the IDUG DB2 North America Tech Conference in May 2015. Netezza is a Data Warehouse Appliance which provides high performance on large volumes of data. Abhik Roy presents the Netezza architecture from a DBA perspective by comparing its features to DB2.
