OPEN TALK: Speaking in Different Tongues: Stabilizing and Synchronizing Our Java and .NET Codebase
Join on Hopin
Michael Demey
Michael Demey
iText Software Group N.V., Research Manager

We had a dream. To have continuously releasable code, and to provide functionality in more than one language without too much effort.
But in the past (like many before us), we didn’t always succeed. Our Open Source codebase is available on two platforms, Java & .NET and it wasn’t an easy task to keep them always in sync and buildable. In the old days we did this manually, risking broken develop branches in both codebases and this meant getting a .NET release out could take a month (or more). There had to be a better way…
In this talk we’ll share how we overcame these hurdles; and how we transitioned from a manually tested and ported codebase to an automated system, where develop is always green!
Our automated system is not final yet. It’s continuously being improved, and we still have many ideas… We’ll share some of these such as the introduction of build agents in the cloud. This would enable us to run tests on different platforms and configurations almost effortlessly.
Guided by a timeline, we’ll go through step by step how we achieved this by introducing different tooling, some in-house and some external. The main part of our talk will be about our Merge Pipeline (trademark pending) based on Jenkins, which forms the backbone of our fully-fledged automated system.
We’ll share its internal details and explain how it handles the different steps that are needed to get a Java branch merged, and automatically ported into the Java and .NET develop branches.
It’s designed in such a way that as little as possible time is wasted by running steps in parallel, keeping track of what was, or was not run already. Code that does not pass Sonar will not make it into develop. Functional tests are in a separate repository but go together with the code they are testing.
We firmly believe that others would benefit from learning the steps we took along the way, and how simple tooling can be used to introduce a merge pipeline to help the development process at any company.

OPEN TALK: Observability at Scale: Using AWS Services to Monitor the Performance of Your Microservices
Join on Hopin
Andy Hopper
Andy Hopper
Amazon Web Services, Principal Specialist Solutions Architect

Detecting and diagnosing performance issues in microservices can be difficult due to the distributed and decoupled nature of microservice-based architecture. While it is important to have metrics on the individual components, it may be necessary to follow the progress of a request as it travels across multiple service boundaries in order to identify problems. In this session, we will explore how AWS provides native monitoring, logging, alarming, and dashboards with Amazon CloudWatch and tracing through AWS X-Ray and OpenTelemetry to provide the 3 pillars (Metric, Logs & Traces) of an overall observability solution.

Join on Hopin
Taylor Smith
Taylor Smith
Palo Alto Networks, Bridgecrew Senior PMM

Cloud security in most dev environments is broken. With ever-changing environments, engineers focused on features, and DevOps enabling incredible agility, traditional cloud security can't keep up. Even with a security resource at hand, the chance of catching each bad Terraform default or hidden * in a wide-open IAM policy is near impossible across endless cloud services. In this session, we'll show how (with very little effort) you can adopt DevSecOps with the right training, tools, processes and strategy. You’ll get practical advice and tactical tips to start implementing IaC security scanning and fixing security issues right away.

OPEN TALK: Developer-First DAST: The Missing Tool in Your AppSec Toolkit
Join on Hopin
Oliver Moradov
Oliver Moradov
NeuraLegion, VP

To truly scale application security testing, developers need to maintain their role in the security process beyond SCA and SAST, continuing the automation you are already achieving and rely less on manual testing.

Traditional DAST scanners are a blocker to this automation. They are hard to use, impossible to integrate, not developer friendly and produce too many false positives. This results in crippling human bottlenecks that stifle CI/CD, whether it's the need for security to constantly tweak scanners or the drain of manually validating vulnerabilities.

Either way, technical and security debt is compounded, resulting in insecure product hitting production. Change is needed, and fast.

In this session with Bar Hofesh, CTO and Co-Founder at NeuraLegion, you will discover:

1. Key features that your dev-first DAST needs to enable developers to take ownership of security

2. How you can detect, prioritise and remediate security issues early, automated in the pipeline

3. Insights into reducing the noise of false alerts to remove your manual bottlenecks to shift left

4. Steps you can take to achieve security testing automation as part of your CI/CD, to test your applications and APIs.

OPEN TALK: Let’s Play Tag: DevSecOps Edition! Automated IaC Resource Tagging Strategy for Security Policy Enrichment
Join on Hopin
Steve Giguere
Steve Giguere
Bridgecrew, Developer Advocate

Through GitOps practices, automated security checks, and Infrastructure as Code (IaC) strategic tagging automation, we can begin to build pre-flight and runtime policy-as-code to ensure that misconfigured and insecure resource definitions are caught prior to deployment. When resource misconfiguration or drift is discovered at runtime, a consistent tagging strategy allows resources to be traced back to the appropriate commit. This reveals a best fix location and author to vastly reduce MTTR. To show how this all works, we'll use a combination of open source solutions: Checkov (IaC Policy and Scanning) + Yor (IaC Tag and Trace)

OPEN TALK: Kafka or Pulsar: Which One Did I Choose to Build My Streaming Service?
Join on Hopin
Chris Bartholomew
Chris Bartholomew
DataStax, Streaming Engineering

In early 2019, Chris decided to start a messaging and streaming SaaS business. He knew he wanted to build on open source technologies. Apache Kafka is the most popular open source technology in this space and would have been the easy answer. Instead, he decided to build using the lesser known alternative, Apache Pulsar.

In this talk, Chris will go over the key reasons why he felt (and still feels) that Apache Pulsar was the ideal choice for a message streaming SaaS platform. He will discuss the key architectural advantages of Pulsar over Kafka, including how Pulsar uses the open-source Apache BookKeeper project to its advantage. I will contrast and compare the open-source feature sets of Pulsar and Kafka. He will also discuss why running Apache Pulsar in Kubernetes simplifies operations and enables me to build a multi-tenant, elastic SaaS service.
