Cost-Efficient and Application SLA-Aware Client Side Request Scheduling in an Infrastructure-as-a-Service Cloud

JUSUF is a petaflop supercomputer operated by Jülich Supercomputing Centre at Forschungszentrum Jülich as a European supercomputing and cloud resource. JUSUF was funded via the ICEI project and especially serves the Human Brain Project and PRACE via ICEI and the Fenix Research Infrastructure. The system consists of two parts, an HPC cluster partition and an Infrastructure-as-a-Service cloud partition. The system entered production phase in spring 2020. It is based on the Bull X400 product family with AMD Rome processors, partially accelerated by Nvidia V100 GPUs, and Nvidia Mellanox HDR InfiniBand.

Massively Multiplayer Online Games (MMOG) are a challenging class of applications: they combine high demands on real-time user interactivity and adaptability with the problem of an efficient and economic utilization of resources for the dynamically changing number of users. This chapter studies how MMOG can benefit from Cloud Computing with its Infrastructure-as-a-Service (IaaS) approach to cost-efficient leasing resources on demand. The chapter makes two major contributions: (1) a new lifecycle model for the development of adaptable MMOG expresses major design and execution aspects of Cloud-based MMOG, and (2) a resource management system RTF-RMS implements efficient load balancing for MMOG on Clouds. The authors illustrate how their lifecycle model and RTF-RMS system support the efficient development and execution of adaptable MMOG on Clouds and demonstrate the advantages of their approach in an experimental evaluation.

Distribution Cost

The overlay networks composed of residential gateways (i.e. home-box) leverage their storage and upload capacity to achieve scalable and cost-efficient content distribution. In this chapter, we present the architecture of the home-box overlay for video on demand services, with the network-aware request redirection and content caching strategy that optimizes the resource usage at both network and client side, for reducing the overall distribution cost. The proposed system is compared with existing solutions through comprehensive simulations. The results demonstrate the advantage of network-aware and popularity-based caching strategy, with reduced the overall cost of the VoD services.
