Erlang Powered Rabbits - Lukas Larsson Erlang VM Core Comitter at Erlang Solutions ABSTRACT Erlang is a programming language designed to make it easier to handle many parallel interactions. It was originally intended for usage in telecom, but has since spread to messaging, databases, fintech systems, and message brokers such as RabbitMQ. Join me as we explore what makes Erlang uniquely suited for solving the problems in these domains, and what RabbitMQ does to leverage its strengths. • Timecodes 00:00 - 06:11 - A bit of History 06:10 - 11:19 - Process and Distributed Computing 11:20 - 12:54 - Erlang in Rabbits 12:55 - 15:27 - Fairness 12:55 - 21:40 - Isolation 21:41 - 24:14 - Erlang in RabbitMQ 24:15 - 26:27 - Parallelism 26:28 - 27:11 - Process Characteristics 27:12 - 28:39 - Distributed Computing 28:40 - 32:47 - What about Erlang the Language? 32:48 - 43:56- QnA • Follow us on social: Twitter: https://twitter.com/RabbitMQSummit LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

What's New in RabbitMQ Streams? | Arnaud Cogoluègnes - Software Engineer at VMWare ABSTRACT RabbitMQ 3.9 introduced streams, a new log-type data structure. What is the state of RabbitMQ Streams after one year of existence? Feedback from users helped stabilize and optimize it. The ecosystem grew with new client libraries in several programming languages. But streams are far from feature-complete: super streams, to scale out publishing and consuming, and single active consumer, to handle consumer concurrency, are the two major features coming up. Join this session to find out about the present and future of RabbitMQ Streams! • Follow us on social: Twitter: https://twitter.com/RabbitMQSummit LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

Write fast, reliable, and secure clients! | Carl Hörberg - CEO at 84codes ABSTRACT The RabbitMQ website has over 70 clients listed, so there is naturally a vast array of client libraries. Among these, there are several great, unofficial clients developed by the RabbitMQ community, so what could go wrong? As we aim to deliver the best possible clients, we need to be sure to keep everything above-board and high quality. Carl Hörberg (CloudAMQP) has contributed to several client libraries lately, including the amqp-client for Crystal, the TypeScript client both for Node.js and browsers (using WebSocket), and the amqp-client for Ruby, where the new Ruby client is more than 4 times faster than other Ruby clients. In this presentation, Carl talks about how to write fast clients that are also reliable and secure. He also tells you why he decided to write some new libraries. • Follow us on social: Twitter: https://twitter.com/RabbitMQSummit LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

Managing RabbitMQ Usage at Scale for Bloomberg’s Trading Systems | Andrew Cook - Engineering Team Lead at Bloomberg ABSTRACT Learn how Bloomberg's Order Management Systems (OMS) leverage RabbitMQ! We'll talk about how we use RabbitMQ for OMS applications. As you can imagine, these systems require particularly complex topologies in order to satisfy critical service-level requirements related to performance, reliability, scalability, and client isolation. The evolution of our OMS topologies posed some common problems. As these systems grew and evolved, virtual hosts became bloated. Workflows that started as simple publisher/consumer pipelines required more steps inserted. Connection strings needed to be changed to adopt amqpprox – a proxy for the RabbitMQ brokers. • Timecodes: 00:00 - 05:40 - What is an OMS? 05:41 - 08:17 - Our Score 08:18 - 13:21 - The System 13:22 - 21:37 - Why RabbitMQ 21:38 - 28:51 - Externalized Application Config 28:52 - 33:52 - Use Case 33:53 - 35:43 - Looking Forward 35:44 - 44:40 - QnA • Follow us on social: Twitter: https://twitter.com/RabbitMQSummit LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

Pushing RabbitMQ to the limit | Gabor Olah - RabbitMQ Consultant at RabbitMQ ABSTRACT One of the most frequent questions I’m asked about RabbitMQ is whether it can do a specific throughput. My answer is almost always is that it depends. In this talk I will explain what affects RabbitMQ performance through practical examples. I will give a practical introduction to how to use PerfTest, the “official” performance testing tool for RabbitMQ to simulate different workloads over different topologies. • Follow us on social: Twitter: https://twitter.com/RabbitMQSummit LinkedIn: https://www.linkedin.com/company/27159258 • Looking for a unique learning experience?

Zero Trust RabbitMQ with HashiCorp Vault | Rob Barnes - Senior Developer Advocate at Hashicorp ABSTRACT Securing RabbitMQ in a Zero Trust environment has multiple layers that need consideration. The first is implementing the principle of least privileged access to RabbitMQ, and the second is ensuring the confidentiality and integrity of application data. Both of which are difficult challenges to solve and introduce substantial operational overheads. In this demo-driven talk, I will show how you can use HashiCorp Vault to offset the operational overhead of Identity and Access Management. I will also show you how you can use HashiCorp Vault’s API to implement a simple workflow that offsets the complexity of cryptography to Vault. By the end of this talk, you will learn how to configure Vault using Terraform to broker application identity on behalf of RabbitMQ and refactor a simple Go application to implement this authentication workflow. You will also learn how to implement symmetric and asymmetric encryption of your application data before placing it on RabbitMQ message queues. • Follow us on social: Twitter: https://twitter.com/RabbitMQSummit LinkedIn: https://www.linkedin.com/company/code-sync/ • Looking for a unique learning experience?
