Performance Evaluation of Microservices Architectures using Containers

TL;DR: In this article, the authors compare the performance of CPU and network running benchmarks in the two aforementioned models of microservices architecture and provide a benchmark analysis guidance for system designers, which can be used to develop applications based on monolithic architectures where the whole system runs inside a single container or inside a microservices architectures where one or few processes run inside the containers.

SustNMS: Towards service oriented policy-based network management for energy-efficiency

TL;DR: An energy-efficient policy-based network management architecture that enables the enforcement of energy-efficiency according to high-level business decisions on how to coordinate the trade-off between energy savings and the potential impact on the network operation is presented.

Selecting resource allocation policies and resolving resource conflicts

TL;DR: In this article, a method for allocating computing resources in a datacenter cluster is provided, which includes the steps of: creating multiple, parallel schedulers; and automatically selecting a resource allocation method for each of the scheduler based on one or more of a workload profile, user requirements, and a state of the data center cluster.
