[OpenStack 하반기 스터디] DPDK & OpenStack why?

DPDK aims to improve network performance in OpenStack by reducing latency. The hypervisor was not designed for network functions and introduces bottlenecks through interrupts and copying. DPDK runs in userspace and uses poll mode drivers to bypass the kernel for packet processing, improving throughput. A proof of concept showed DPDK-accelerated Open vSwitch handled over 30Gbps of traffic with low CPU usage, compared to normal OVS which topped out at 10Gbps. While the test had limitations, DPDK offers potential to accelerate features like SR-IOV, VMQ, and offloads.

Korejanai Story

Kentaro Takeda

Kentaro Takeda and Kensuke Ishizu of NTT DATA presented on common misunderstandings enterprises have about OpenStack and how it differs from traditional infrastructure models. They explained that OpenStack is software for building infrastructure as a service (IaaS) and outlined key differences between IaaS and traditional server consolidation approaches. Specifically, IaaS follows a "cattle not pets" approach where infrastructure resources are treated as interchangeable and provisioned on-demand, unlike dedicated server silos. The presentation provided examples of how enterprises sometimes try to use OpenStack in ways that don't align with its IaaS model, resulting in projects deemed "Korejanai" or "not it".

How to integrate OpenStack Swift to your "legacy" system

Masaaki Nakagawa

The document discusses two case studies of integrating OpenStack Swift object storage into legacy systems. Case 1 involves using Swift as backup storage for a legacy backup server. Issues arose due to the backup software not supporting Swift's REST API. Mounting Swift via Cloudfuse helped pass backups with workarounds. Case 2 uses Swift with a Cloud Storage Gateway (Fobas CSC) to provide a file server across locations, addressing Swift's lack of file protocols and small file performance. The combination met requirements and provided good performance. The document concludes cloud gateways can help integration but limit Swift benefits, and improving gateways and native cloud applications unlock more value.

Internet of manufacturing and Open Source

Ian Skerrett

The document discusses collaborating on open source software projects for Internet of Things (IoT) platforms. It describes the Eclipse Foundation's role in supporting open source IoT projects with over 250 members. It advocates that open source lowers barriers for collaborative development, developers, interoperability, and adoption. It presents Bosch's strategy to support an open source IoT platform to avoid vendor lock-in and allow customers and partners choice. The Eclipse IoT projects aim to support Industry 4.0 standards through implementations of tools, services, and a testbed for integrating devices and systems.

Gluster in Japan 2012-2013

Keisuke Takahashi

The document summarizes the use of GlusterFS in Japan over the past year.
