- Visibility in Scale - The Enabler of Constant Change
Yes! let's open our morning with a tech talk about visibility. This time Nikita Ostrovsky comes and visit us from Outbrain NY office. His talk will be about how in an ever-changing environment, visibility is the key to solving scalability issues, capacity problems, troubleshooting, as well as a host of others. In this talk, we will discuss Outbrain's metrics environment, the overall scale of it, and how it evolved to be able to support a massive migration to Kubernetes. About Nikita: Nikita is a DevOps Manager that leads the Visibility team at Outbrain. He's been in the SRE/DevOps space for over 10 years and primarily focuses on bringing sane metrics, logging, event streaming and alerting solutions to the organization at large. Agenda: 9:30-10:00: Coffee & pastry 10:00-10:40: Nikita 10:40: Q&A
- Real Life Cassandra 2.x to Cassandra 3.x Upgrade".
Join us to learn how we upgraded Cassandra with zero downtime on our production environment. We will share all the tricks and tweaks and hold nothing back! For a slight preview, you can check Outbrain tech blog post here outbra.in/2Cvd50E. We are to provide an outlook on how we migrated our clusters from Datastax 4.8.x to Apache Cassandra 3.1. This can be considered as real-life HOWTO because even though the high-level upgrade procedure is well known there are many caveats along the way. In addition, we will cover some details on the Cassandra 3.x storage engine internals changes and how this can help to get higher throughput and lower latency from existing clusters. We will dive into Cassandra repairs - which are known to be quite problematic in Cassandra 3.x and come up with our approach for this. About Sergey: "For the last two years at Outbrain I was DevOps focusing on Cassandra and Elasticsearch. In addition to simply managing Cassandra clusters, I worked closely with several development teams designing Cassandra schemas and optimizing cluster performance - from schema and application access patterns to hardware tweaks. Prior to going into the DevOps world, I worked as database developer focusing on Microsoft SQL Server".
- A Strategy For Building Application Suites
As part of ILTechTalks week 2018, we invite you to the following talk: A Strategy For Building Application Suites Abstract: Your company grows and its business portfolio becomes richer. You enter a phase in which there is no longer one single customer-facing application. Multiple applications are usually then split to different independent teams and each serves a different business functionality. Enterprise-grade software development will require that all of these applications will have a common product backbone: Unified look-and-feel, single-sign on, shared entity management, access control, common services and so on. Development organizations struggle to determine the right amount of decoupling, reuse, and interoperability. In this talk, I will cover different approaches for building application suites and attempt to state pros and cons for each proposed strategy. About Nir: Nir Hemed, VP Core Products at Trax Retail. Passionate about the relation between architecture and people. Leading a technology group which is accountable for Trax's data acquisition and digitization layers. Responsible for product design, specification, development, and execution.
- Introduction to Zero-Knowledge Proof
How can you prove who you are and what you know without revealing anything else, even to the person or computer you are proving it to? For example, you want to prove you know a password, but not anything about the password, and the service you are accessing might be compromised! Zero-knowledge proofs, first conceived in 1985, won the first Gödel Prize in '93. They are a fascinating solution to a problem that seems impossible at first (and second) glance. About Omer: Omer is the CEO and co-founder of NeoWize.He has served in 8200 for 12 years, has a BA in Mathematics and CS, and won the World Universities Debating Championship.
- Taking The Pain Out of Data Science- RecSys ML framework over Spark
As part of ILTechTalks week 2018, we invite you to the following talk: Taking The Pain Out of Data Science- RecSys ML framework over Spark Outbrain is the world’s largest discovery platform, bringing personalized and relevant content to audiences while helping publishers understand their audiences through data. Its recommender system is serving billions of content recommendations daily, based on millions of hourly user interactions. Our predictive models span over a variety of supervised learning techniques, ranging from content-based recommenders, through behavioral models and all the way to collaborative techniques such as factorization machines. Agility and stability are crucial aspects of the system. This talk will cover our journey towards solutions that would not compromise neither on scale nor on model complexity, and design a dynamic framework that shortens the cycle between research and production. We will cover the different stages of the framework, including important take away lessons for data scientists as well as software engineers. About Shaked: Shaked is an Algorithm Engineer and Tech Lead at the Personalization team @ Outbrain's Recommendations group, developing large-scale machine learning algorithms for Outbrain's content recommendations platform, from data science to production.
- Microservices Component Tests with Docker Compose
As part of ILTechTalks week 2018, we invite you to the following talk: Microservices Component Tests with Docker Compose Doing rigorous automated testing is key to successful CI/CD pipelines. Unit tests covers your logic, but does not cover full flows, and bypasses or mocks your dependencies. Canary testing requires deploying your new service version, and fits a late stage in the CD pipeline. In between lies Component Testing. We’ll describe how to use Docker Compose to dynamically bootstrap a lightweight synthetic test environment in which a microservice can run isolated from the world, but think it is in a real production environment. This environment is complete with mocks or stubs of all service dependencies: databases, other microservices, web services, cache servers, etc. The tested service communicates with these dependencies in the exact same fashion it would on production. Tests run identically on developer machines and the CI pipeline, and allows fast automated testing of the service in a configuration as close to production as possible. About Ran: Ran Peled is Chief Architect at MyHeritage, with over 30 years of software development experience, and expertise in large-scale Internet applications. Prior to MyHeritage, he held several management and architecture roles at Internet infrastructure company BackWeb Technologies (NASDAQ: BWEB), the IDF, and several other companies.
