More and more organizations are being run dependent on information systems. This makes information systems a pivotal component of our lives. Because of globalization and harsh competition, strategic cost management has become essential to keep or gain competitive advantage. These two trends make the investigation of Total Cost of Ownership (TCO) for information systems crucial. To this end, a systematic mapping study (SMS) is presented to identify the use of TCO in information systems context. A summary of the findings after analyzing and synthesizing 75 relevant publications are as follows: (1) an increased interest in TCO for information systems is observed over the years; (2) 76% of the selected publications lack validation and evaluation; (3) the main motivation behind the 72% of the publications is reduction of TCO; (4) essential means of reducing TCO are cloud computing, SaaS model, and multi-tenancy; (5) TCO calculations are also generally made to compare cloud-based infrastructures with in-house infrastructures and SaaS model with on-premise software; (6) TCO is an important criterion in making investment decisions for information systems such as ERP, CRM.

“…is situation is evident for high-performance computing (HPC) infrastructures, where the sum of the energy bills over a supercomputer's lifetime is comparable to the acquisition cost and represents one of the most relevant elements of the total cost of ownership [3]. is is because energy is used not only for computation but also for cooling, communication, storage, and display [4].…”

Energy consumption is one of the major issues in today’s computer science, and an increasing number of scientific communities are interested in evaluating the tradeoff between time-to-solution and energy-to-solution. Despite, in the last two decades, computing which revolved around centralized computing infrastructures, such as supercomputing and data centers, the wide adoption of the Internet of Things (IoT) paradigm is currently inverting this trend due to the huge amount of data it generates, pushing computing power back to places where the data are generated—the so-called fog/edge computing. This shift towards a decentralized model requires an equivalent change in the software engineering paradigms, development environments, hardware tools, languages, and computation models for scientific programming because the local computational capabilities are typically limited and require a careful evaluation of power consumption. This paper aims to present how these concepts can be actually implemented in scientific software by presenting the state of the art of powerful, less power-hungry processors from one side and energy-aware tools and techniques from the other one.
