Virtualization technologies and server consolidation are the main drivers of high resource utilization and energy efficiency in modern Data Centers. However, some combinations of virtual machines into the same server may lead to severe performance degradation. This performance degradation is known as virtual machine interference. In a typical Data Center,(More)
Unikernels are a promising alternative for application deployment in cloud platforms. They comprise a very small footprint, providing better deployment agility and portability among virtualization platforms. Similar to Linux containers, they are a lightweight alternative for deploying distributed applications based on microservices. However, the comparison(More)
Service Function Chaining (SFC) is a prominent research field in networking with several proposals from industry and academia. The lack of tools to check SFC path correctness forces network operators to spend a significant effort in guaranteeing that an SFC configuration meets their intent behavior. This work presents the SFC Path Tracer, a tool for(More)
