Search at Etsy poses significant challenges. Our marketplace is filled with millions of unique, short-lived items and people trying to find them over 13 million times a day. In this session we'll discuss many of the solutions we've engineered to meet these challenges including, the evolution of indexing at Etsy, how HBase and Hadoop have taken indexing from hours to minutes, how and why we use bittorrent for Solr replication, how we track search performance, our approach to shave crucial milliseconds off every search, and an overview of our continuous deployment strategy, web / search config integration and A/B testing and analytics.

Automating it management with Puppet + ServiceNowPuppet
As the leading IT Service Management and IT Operations Management platform in the marketplace, ServiceNow is used by many organizations to address everything from self service IT requests to Change, Incident and Problem Management. The strength of the platform is in the workflows and processes that are built around the shared data model, represented in the CMDB. This provides the ‘single source of truth’ for the organization.
Puppet Enterprise is a leading automation platform focused on the IT Configuration Management and Compliance space. Puppet Enterprise has a unique perspective on the state of systems being managed, constantly being updated and kept accurate as part of the regular Puppet operation. Puppet Enterprise is the automation engine ensuring that the environment stays consistent and in compliance.
In this webinar, we will explore how to maximize the value of both solutions, with Puppet Enterprise automating the actions required to drive a change, and ServiceNow governing the process around that change, from definition to approval. We will introduce and demonstrate several published integration points between the two solutions, in the areas of Self-Service Infrastructure, Enriched Change Management and Automated Incident Registration.
Simplified Patch Management with Puppet - Oct. 2020Puppet
Does your company struggle with patching systems? If so, you’re not alone — most organizations have attempted to solve this issue by cobbling together multiple tools, processes, and different teams, which can make an already complicated issue worse.
Puppet helps keep hosts healthy, secure and compliant by replacing time-consuming and error prone patching processes with Puppet’s automated patching solution.
Join this webinar to learn how to do the following with Puppet:
Eliminate manual patching processes with pre-built patching automation for Windows and Linux systems.
Gain visibility into patching status across your estate regardless of OS with new patching solution from the PE console.
Ensure your systems are compliant and patched in a healthy state
How Puppet Enterprise makes patch management easy across your Windows and Linux operating systems.

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.
The Art of the Pitch: WordPress Relationships and SalesLaura Byrne

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
