"Index-Free Log Aggregation With Kafka" by Kresten Krab, CTO/Co-founder @ Humio

We are seeing a rise in a new generation of logging solutions. Traditional approaches have been based on database indexes, but the next wave of log management platforms is a combination of techniques including streaming queries, in-memory processing, brute-force search, and filtering. We call this *Index-Free Logging*.

In this talk, we will provide an overview of the advantages of Index-Free Logging, and how we’re implementing it in Humio, a new log analytics system with a novel storage and query engine for events logs and traces. Humio was built from the ground up as a multi-tenant on-prem system so you can install it behind your own firewalls or in your own cloud infrastructure.

In a Humio setup, we then use Kafka for two things: buffering ingest and as a sequencer of events among the nodes of a Humio cluster. We love Kafka — it has made implementing a distributed system significantly easier than if we had to do the distributed queue from scratch. Using Kafka as a building block has allowed us to focus our attention on building a fast and easy search experience.


“Observability - what you don’t learn at school” by Pavlo Baron, CTO/Co-founder @ Instana

Everybody tells you that you need to build and keep your systems observable. Besides there is a lot of confusion and marketing speak around the term “observability” itself, what theoretic observability means isn’t necessary what’s needed in a modern system. The term and the topic are loaded, no question, and this talk is intended to get all the things modern observability in order without any methodological or evangelistic bias.

Pavlo Baron has over 25 years of broad experience in IT industry. He worked as enterprise architect and engineering lead in companies of different sizes and markets, such as Sixt and UniCredit. Pavlo has also helped multiple startups deliver successful technical products from the beginning, and ran an own small business specialising in solution delivery in the fast-growing internet business back in the days.

As consultant, Pavlo helped enterprises of different sizes, such as Deutsche Bank, BMW, ING-DiBa, Fiducia, define and establish strategic moves towards modern technologies and Big Data. Pavlo’s passion are high-performance, distributed systems and large data sets – the infrastructure behind Big Data - and data science, the areas he’s pioneered very early for the companies he worked for.

Pavlo is frequent speaker at international conferences such as QCon, TechMesh, GOTO. He also has written four IT books: “Big Data for IT decision makers”, “Erlang/OTP”, “Pragmatic IT Architecture” and “Fragile Agile”.
