The document describes Riley, a new data center network design that uses extremely simple switches without a switch operating system (OS). Riley aims to simplify switches by removing unnecessary components found in traditional designs. It shows that Riley switches can provide comparable throughput, job completion times, and end-host resource usage to traditional IP-based designs, but with significantly less switch resource usage in terms of TCAM, SRAM, CPU, and memory requirements. The goal of Riley is to design the simplest possible data center switch.

LinkedIn's Approach to Programmable Data CenterShawn Zandi
Highly available and tunable control planes are difficult to build and manage. Is there an alternate way to build a control plane for cloud scale fabrics that will reduce operational expense (coming as close to zero touch provisioning as possible), while allowing the network to be tuned in near real time based on telemetry and application requirements? LinkedIn is currently working on such a control plane, starting from the concept of layering different control plane functionality. This talk will provide an overview of the functional division, consider some tools which can be used to meet each, and the consider the resulting operational profile.

This talk aims to describe the journey a systems engineer had as part of an automation assignment with the network management team. building from lessons learned and challenges faced with system automation for the last three years. Where and how to start the journey? what to avoid? what to prioritize? how to overcome the lack of network skills for the automation engineer and lack of automation and Linux/Unix skills for network engineers. what challenges were faced and ho w to overcome them? what fights to win, and which to give up? where do I see network automation and configuration management as a systems engineer? what are the status quo and future expectations?
This study guide is intended to provide those pursuing the CCNA certification with a framework of what concepts need to be studied. This is not a comprehensive document containing all the secrets of the CCNA, nor is it a “braindump” of questions and answers.
I sincerely hope that this document provides some assistance and clarity in your studies.
KPN ETL Factory (KETL) - Automated Code generation using Metadata to build Da...DataWorks Summit
Being one of biggest and oldest telecom providers in Netherlands with multiple acquisitions over last few decades left KPN with 1500+ data sources and more than 25 teams working with different tools like Teradata, Informatica, Oracle, OBIEE, Hadoop etc. This resulted into a lot of technical debt and also duplicated data on various systems with complex data relationship. Thus resulting into data quality issues and long processing times to get meaningful insights into business.
This created need for an unified way of Ingesting, Storing and Transforming data to be consumed and processed at multiple stages where KETL Framework was born.
Our journey so far:
Instead of developing mappings and workflows or handcrafted SQL Code, Business teams started writing metadata about their sources and dependency between them using macro based excel files or Django based YAML file generator. These files are used by the KETL framework to generate appropriate Hive/Spark/Informatica/Oracle/Teradata Code along with Airflow Scheduler DAG with schedule and dependency as Code.
Additionally all the environments, configuration and access rights are also managed via YAML files with Ansible thus enabling us to view each change as code. This made teams self sufficient where they can build their own Dev/Test environment to validate their metadata and target model structure before deploying to production.
Benefits:
- On-boarding new sources and integrating with existing data store takes less than a week
- Everything is maintained in Git, giving full visibility of changes along with their timelines
- Minimising technical depth and allowing business teams to focus on data instead of tooling
- Easier adoption of newer tools and path of least resistence for decommissioning of legacy stack
- KISS Architecture, easier to maintain and scale
- Reducing bureaucratic processes and design for transparency
What keeps us busy:
- Adding a Test Framework to enable users with BDD tests using the same metadata
- Adding functionality to generate complex code structures
- Using advanced CI/CD processes like Jenkins pipeline for faster deployments
- Integration with new tools and technologies both enterprise and opensource.
Tools/Technologies used:
- Hortonworks HDP - HDFS, Yarn, Hive, Spark, LLAP, Tez
- User and Access Management - Ranger, Knox, Kerberos, LDAP, SSSD, Linux ACL's
- ETL & DWH Tools - Informatica, Informatica BDM, Teradata, Querygrid, Aster etc.
- Reporting - OBIEE, Tableau, Zeppelin Notebooks
- Monitoring - Grafana, Zabbix & ELK
- Scheduler - Airflow
- Orchestration - Ansible
- Code - Python, YAML, Jinja2
- CI/CD - Git, Artifactory, Jenkins

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.

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.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
