it-novum

Ceph is the most widely deployed storage technology used with OpenStack, most often because it's an open source, massively scalable, unified software-defined storage solution. Its popularity is also due to its unique and optimized technical integration with the OpenStack services and its pure-software approach to scaling. In this session, we'll review how Ceph is integrated into Nova, Glance, Keystone, Cinder, and Manila and demonstrate why using traditional storage products won’t give you the full benefits of an elastic cloud infrastructure. We’ll also cover the flexible deployment options, available through Red Hat Enterprise Linux OpenStack Platform and Red Hat Ceph Storage, for seamless operations and key scenarios like disaster recovery. We'll discuss architectural options for deploying a multisite OpenStack cluster and cover the varying levels of maturity in the OpenStack services for configuring multisite. This session will also show how other technologies are using OpenStack Ceph to increase performance and reduce power consumption, such as Intel SSDs. This will include reference architectures and best practices for Ceph and SSDs.

Xiaoyi Lu from Ohio State University presented this deck at the OpenFabrics Workshop. "Single Root I/O Virtualization (SR-IOV) technology has been steadily gaining momentum for high performance interconnects such as InfiniBand. SR-IOV can deliver near native performance but lacks locality-aware communication support. This talk presents an efficient approach to building HPC clouds based on MVAPICH2 and RDMA-Hadoop with SR-IOV. We discuss high-performance designs of the virtual machine and container aware MVAPICH2 library over SR-IOV enabled HPC Clouds." This talk will also present a high-performance virtual machine migration framework for MPI applications on SR-IOV enabled InfiniBand clouds. The MVAPICH2 software for building HPC Clouds presented in this talk is publicly available. We will also discuss how to leverage the high-performance networking features (e.g., RDMA, SR-IOV) on cloud environments to accelerate data processing through RDMAHadoop package, which is publicly available. Comprehensive performance evaluations on NSF-supported Chameleon Cloud show that our design can deliver the near bare-metal performance."

Budapest Data/ML - Building Modern Data Streaming Apps with NiFi, Flink and Kafka Apache NiFi, Apache Flink, Apache Kafka Timothy Spann Principal Developer Advocate Cloudera Data in Motion https://budapestdata.hu/2023/en/speakers/timothy-spann/ Timothy Spann Principal Developer Advocate Cloudera (US) LinkedIn · GitHub · datainmotion.dev June 8 · Online · English talk Building Modern Data Streaming Apps with NiFi, Flink and Kafka In my session, I will show you some best practices I have discovered over the last 7 years in building data streaming applications including IoT, CDC, Logs, and more. In my modern approach, we utilize several open-source frameworks to maximize the best features of all. We often start with Apache NiFi as the orchestrator of streams flowing into Apache Kafka. From there we build streaming ETL with Apache Flink SQL. We will stream data into Apache Iceberg. We use the best streaming tools for the current applications with FLaNK. flankstack.dev BIO Tim Spann is a Principal Developer Advocate in Data In Motion for Cloudera. He works with Apache NiFi, Apache Pulsar, Apache Kafka, Apache Flink, Flink SQL, Apache Pinot, Trino, Apache Iceberg, DeltaLake, Apache Spark, Big Data, IoT, Cloud, AI/DL, machine learning, and deep learning. Tim has over ten years of experience with the IoT, big data, distributed computing, messaging, streaming technologies, and Java programming. Previously, he was a Developer Advocate at StreamNative, Principal DataFlow Field Engineer at Cloudera, a Senior Solutions Engineer at Hortonworks, a Senior Solutions Architect at AirisData, a Senior Field Engineer at Pivotal and a Team Leader at HPE. He blogs for DZone, where he is the Big Data Zone leader, and runs a popular meetup in Princeton & NYC on Big Data, Cloud, IoT, deep learning, streaming, NiFi, the blockchain, and Spark. Tim is a frequent speaker at conferences such as ApacheCon, DeveloperWeek, Pulsar Summit and many more. He holds a BS and MS in computer science.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.
