About Dev Days

The region's top developer conference

This year's Dev Days will look towards the event horizon of 2017 and beyond. As part of the preparation for future challenges, we're going to introduce Spring 5 as a brand-new generation of the framework and selected feature highlights in the context of modern system environments.

By examining impact mapping, the conference will help your software survive and thrive in a world of shifting tech. Communication, organizational learning, proper risk assessment, and the pitfalls of Groupthink will be examined through spacefaring attempts made by NASA, helping us learn from the past when looking into the future of software development.

Schedule - Open Day - Saturday, 13th of May

Join us at Terme Tuhelj on Saturday 13 May for keynotes by Infobip's lead developers and international guest lecturers.

Gojko
Adzic

Software delivery consultant

Abstract: Migrating to serverless

We moved a large collaboration platform from Heroku to AWS Lambda, and reduced hosting costs by 50% even though the number of active users grew by 50%, and replaced our biggest bottleneck with something that scales effortlessly. This is an experience report from that journey.

Serverless architectures bring significant benefits, but have a major impact on architecture, require teams to re-think how to approach sessions, storage, authorization and testing. You'll find out what worked well for us, where we got stuck, and how we made it work well at the end.

The Shuttle case

January 28th 1986 - the space shuttle Challenger explodes just one minute after launch. As the world looked on horrified, few realised that this was an inevitable accident that had been predicted by the designers for years. Indeed, the day before the key engineers believed that there was “essentially a 100% probability of disaster”.

Then in Feb 2003 – the Space Shuttle Colombia burns up on re-entry and the entire crew perish. The chilling fact was that this was a management repeat of the Challenger disaster – NASA had not truly learned the lessons of the past.

Izabel
Jelenic

Infobip co-founder and CTO

Short bio:

Having co-founded Infobip in 2006, Izabel devoted remarkable energy to building what would become one of the world’s top-performing A2P SMS systems. Today, Infobip processes 300 million messages every day - more than regional carriers combined!

Over the years, he’s been heavily focused on building optimal client experience, struggling with all the challenges that every telecoms technical lead knows all too well. It’s been everything from trivial slow disk issues to huge Linux storage, from SCCP layer snooping to handling DDoS attacks, from handling a huge monolithic service to unbundling services and their infrastructure.

Company’s transition from two to 140+ developers - lined up in 29 agile teams and 7 R&D centers - brought out new skills and duties for its CTO. Yet, he remained a passionate developer at heart, trying to steal a moment or two to keep up with the latest technologies and build them into Infobip’s platform.

Mario
Zagar

Senior Software Architect/Division Lead

Abstract: Kafka's role in Infobip data pipeline architecture

Kafka is used for building real-time data pipelines and streaming apps; it is horizontally scalable, fault-tolerant and fast. In this talk I will present our use case for using Kafka to enable real-time processing of tens of thousands of messages per second and will describe our journey in building our data pipeline with Kafka in the middle. With overview of what Kafka is, how it works I will also show you how we ensure our Kafka cluster is up and running 24/7, how we monitor it, which operational challenges we face on daily bases and what lessons we learned along the way. If you are thinking about using Kafka and are wondering how it would look like and what you can expect this talk is for you.
