The specification of workloads is required in order to evaluate performance characteristics of
application systems using load testing and model-based performance prediction. Defining …

Software architects plan the realization of software systems by assessing design decisions
on the basis of architectural models. Using these models as input, architectural analyses …

In recent years, cloud computing has emerged as a major change in the world of technology,
whereby computing workloads are transferred first from local data centers located within …

A key functionality of cloud systems are automated resource management mechanisms at
the infrastructure level. As part of this, elastic scaling of allocated resources is realized by so …

Large information systems nowadays are required to perform on a Web-scale with millions
of users. Especially in the business-to-business context, the required performance is even …

This thesis presents an approach for the design time analysis of energy efficiency for static
and self-adaptive software systems. The quality characteristics of a software system, such as …

ABSTRACT In Infrastructure as a Service (IaaS) Cloud scenarios, data center operators
require specifications of Virtual Machine (VM) behavior for data center middle-and long-term …

Context. Modern distributed systems are flexible in moving from one configuration to another
during operation in an automated or semi-automated manner, eg, concerning dynamic CPU …

In cloud computing, software engineers design systems for virtually unlimited resources that
cloud providers account on a pay-per-use basis. Elasticity management systems provision …

In cloud computing, typical requirements of Software-as-a-Service (SaaS) applications target
scalability, elasticity, and efficiency. To analyze such properties, software engineers need …
