PLNOG 13: Michał Dubiel: OpenContrail software architecturePROIDEA
Michał Dubiel – TBD
Topic of Presentation: OpenContrail software architecture
Language: Polish
Abstract:
OpenContrail is a complete solution for Software Defined Networking (SDN). Its relatively new approach to network virtualization in data centers utilizes the overlay networking technology in order to achieve full decoupling of the physical infrastructure from the tenant’s logical configurations.
This presentation describes the software architecture of the system and its functional partitioning. A special emphasis is put on a compute node components: the vRouter kernel module and the vRouter Agent. Also, selected implementation details are presented in greater details along with an analysis of their impact on an overall system’s exceptional scalability and great performance.
Open Source Approach to Design and Deployment of Microservices-based VNFOpen Networking Summit

OpenStack & OVS: From Love-Hate Relationship to Match Made in Heaven - Erez C...Cloud Native Day Tel Aviv
"Many developers building OpenStack clouds have “love-hate” relationship with OVS. They love flexibility and elasticity offered by OVS, but hate the network performance and scalability. As emerging technologies such as NFV keep pushing for higher network performance, it becomes critical to improve OVS performance without compromising flexibility, network programmability, and cost.
In this session, we will present an approach that Mellanox has devised with input from key partners and customers to accelerate Virtual Switch dataplane, using the embedded switch implemented in the server Network Interface Card (NIC)’s hardware. This approach supports both ParaVirt vNIC interfaces and SRIOV based vNICs interfaces"
Agile OpenStack Networking with Cisco SolutionsCisco DevNet
A session in the DevNet Zone at Cisco Live, Berlin. One of the key areas of contributions from Cisco within OpenStack has been in the evolution and the development of the OpenStack Networking Service - Neutron. Using Neutron's Modular Layer 2 (ML2) plug-in and advanced services framework, Cisco has integrated products and solutions with the networking service to simplify the deployment of highly scalable, manageable and performant networks. Through this session we will cover and provide details of reference as well as the various OpenStack Neutron plugins/drivers for hardware and software Cisco products including the Nexus 1k/3k/5k/6k/7k/9k, UCS FI, CSR 1kv, ASR1K, CPNR and Application Policy Infrastructure Controller (APIC). The audience will also learn about Group Based Policy API in OpenStack that is based on the ACI Policy model. We will further discuss different OpenStack networking architecture, deployments and understand Cisco’s community code contribution that enable and support IPv6 and NFV related features in Neutron.
OpenStack and OVS: From Love-Hate to Match Made in HeavenOPNFV
Many OPNFV developers building Openstack clouds at scale have a “love-hate” relationship with OVS. They love the flexibility and elasticity offered by a distributed virtual switch operating within each server, but hate the reality of first-gen OVS implementations well-known to be a bottleneck for cloud network performance and scalability. As performance-sensitive VNFs keep pushing for higher data forwarding performance across the NFV network infrastructure, it becomes critical to improve OVS performance without compromising flexibility, network programmability, and cost.
In this session, Mellanox will present a novel way to offload the entire OVS dataplane onto the embedded switch in the server NIC. This approach can not only boost server I/O performance to near line-rate, be it 10G, 40G, or 100G, but also doing so at a fraction of the CPU load needed by existing OVS implementation.
Failure happens, and we can learn from it. We need to think about backups, but also verification of them. We should definitely make use of replication and think about automatic failover. And security is key, but don't forget that encryption is now available in MySQL, Percona Server and MariaDB Server.

Getting more speed, lower latency, lower costs, and keep redundancy for block and network devices. This is what converged networks promise.
Looking at the many advantages, it is somewhat surprising that implementations still lack behind. The services team at SUSE Linux picked up the task, and implemented a virtualization environment based on KVM that runs critical internal services. We want to shed some light on the expectations and pitfalls we encountered during implementation.

Generating a custom Ruby SDK for your web service or Rails API using Smithyg2nightmarescribd
Have you ever wanted a Ruby client API to communicate with your web service? Smithy is a protocol-agnostic language for defining services and SDKs. Smithy Ruby is an implementation of Smithy that generates a Ruby SDK using a Smithy model. In this talk, we will explore Smithy and Smithy Ruby to learn how to generate custom feature-rich SDKs that can communicate with any web service, such as a Rails JSON API.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
