In Blade Runner by P. K. Dick, trained hunters had to retire problematic Androids. We, Developers, are similar to those hunters. Our job is to solve problems. State brings complexity and troubles. Getting rid of it is not always possible. How to make our stateful distributed system highly available?

In these past few years, agile methods became a vital part in the software development process, but are they really applicable for all types of projects and team sizes?
A while ago, their company changed the way they approach project development because the team noticed that standard SCRUM-ish methods aren’t fully compatible for them, so they developed their own, modified version of agile.

Kubernetes (k8s) is the most popular container orchestration system without a doubt. Every day tons of new k8s clusters are created and new k8s practitioners are born. Unfortunately, the excitement of getting straight to the practice usually comes together with a lack of a clear understanding of the k8s architecture, which is very helpful at the begining of any kubernetes implementation project.

In this talk, we’ll discuss services how Kubernetes fits into an infrastructure cost reduction strategy. As part of TKWW’s Engineering Productivity team, Chien has built and operated TKWW’s Kubernetes clusters currently hosting about 75% of TheKnot.com. They reduced compute costs by 40% using Kubernetes. He’ll discuss the various built-in Kubernetes add-ons for logging, metrics, TLS certificate generation, reverse proxy, spot instance management and reporting.

The aim of this session is to glimpse at what DevSecOps is, how you can do it, what you should do and what all the hype is about. Kalle Sirkesalo will walk you through how to set this up in a CI/CD and what are the benefits. After this session, you will be able to have discussions with your team and management about implementing the basics of DevSecOps to your tooling.

“0/100”, or zero defects and 100% first-time-through (FTT), is the holy grail of the Lean manufacturing movement. Zero defects mean that your product or service will have no defects when it is provided to the customer and 100% FTT means that as your in-progress work moves through your workstations or value stream, it is successful on the first try so there is no re-work or in-process repair.

In the old days we write our program, build and just run that program. Now we write it, build it and then we have various ways of running it; maybe just as a binary on a machine of some kind (virtual likely, but doesn’t matter), or package it into a container or maybe take that container and make it part of a bigger deployment (K8s) or maybe deploy it into a serverless or service mesh.

While helping organizations move to microservices and public clouds, Jakub has noticed a lot of common problems. Architecture is described at infrastructure level (k8s, cloud services, etc.) without any focus on domain architecture. Enterprise architects are put in charge of software architecture. Architecture guilds are created without introducing the required practices and culture. QA still thinks that end to end tests are possible.

Most perceive security fixes and improvements as a necessary evil, because security is much “less tangible” than primary product functionality in terms of potential revenue. On top of not bringing any “meaningful” value to the overall system, security comes at a cost of potential performance degradation, as it steals precious CPU cycles and memory from the overall resource pool.

Because being agile is not enough and DevOps is missing something.
This session describes a pragmatic and successful implementation of DevSecOps practices. The presentation gives concrete examples of how to implement several principles that you might need while scaling your practice without introducing unnecessary frictions.
