DSG Seminar Series • Efficiency in Data Systems

Speaker: Tilmann Rabl, University of Potsdam

Location: DC 1302

Abstract: For the longest time, acquiring new hardware resulted in significant software efficiency gains due to exponential improvements of hardware capabilities. Physical limits in hardware manufacturing have brought former niche designs into standard components, such as multiple cores and specialized circuits. Even with these new designs, hardware improvements are decreasing, while software and applications are still becoming increasingly complex and resource demanding. In this talk, we will discuss efficiency of data systems. We will start with a general discussion of system efficiency and look at the design of efficient architectures. Incorporating estimations on hardware and power production carbon intensity, we will then discuss hardware replacement frequencies and try to establish new rules of thumb on the ideal hardware lifecycles for database deployments and discuss implications on database development.
