3 “Big ICT” Big Software Complex systems that evolve over time due to changing usage, deliberate modifications, or a changing context Probably the most complex human-made artifacts, ever Big Data Massive event logs and streaming event data Paradigm shift in science and engineering, from hypothesis-driven to data-driven July 28, Engineering (Big) Software (and Data) From “a priori” to “a posteriori”, a paradigm shift Easier to find defects early (30% cost, 50% time)

4 One Example: Mobile-Cloud ICT Hybrid July 28,

5 Big Software on the Run: Challenges and Key Research Question 1.Tightly connected to society. 2.Closely inter-connected. 3.Diversity in platforms. 4.Reliance on late, even dynamic composition. 5.Potentially chaotic. July 28, How to understand, control, and improve Big Software using “in vivo” software analytics?

6 Big Software on the Run: Approach “In vivo” software monitoring, analysis, and improvement “A posteriori” thinking framework Software analytics as primary software engineering tool July 28,

7 Big Software on the Run: Planning July 28, Jan 2013 Dec 2022
