+Type = "talk"
+Speakers = ["agabekov-roman"]
++++
+
+Tuning MySQL is hard. With over a hundred variables and ever-changing workloads, even experienced developers struggle to squeeze out performance gains. AI is changing that. This talk explores how some AI-powered tools are transforming database performance tuning from a manual, trial-and-error process into a dynamic, automated system. Learn how these tools analyze metrics, map workloads, and apply optimal configurations - saving time, reducing costs, and improving latency, throughput, and resource usage. We’ll also examine the limitations of traditional rule-based scripts and share real-world performance improvements from open source applications like WordPress, Drupal, and Laravel e-commerce platforms.

+
+Many developers focus on optimizing code but overlook a powerful lever for performance: database configuration tuning. In this talk, we explore the real-world impact of MySQL tuning using open source applications like Drupal Commerce and Laravel-based e-commerce platforms. Through a series of tests using JMeter and AWS, we measured latency, CPU usage, and queries per second before and after tuning. The results? Up to 63% reduced latency and improved system efficiency - even without changing a single line of application code. Learn how thoughtful MySQL tuning can deliver big performance wins and why it deserves a place in your development workflow.

+
+Since the announcement of ingress-nginx being deprecated, GatewayAPI adoption has reached an all time high. However with this migration, comes a new approach to thinking about cluster Ingress at all levels. This talk will explain the new paradigm, and present an approach to dealing with secure Ingress in the context of multiple tenants

+Leveraging GatewayAPI, cert-manager, external-dns, and Kong Ingress controller to provide HTTP(S)/GRPC(S) ingress access to services within a Kubernetes cluster in an automated fashion using Kubernetes resource manifests.
+Once configured, we will utilize RBAC and Hierarchical Namespace controller to enforce required namespace labels, which will then be used to secure/configure Ingress hosts and routes in the context of a multi-tenanted cluster.

+Title = "Why segmenting your infrastructure into tiers makes your infrastructure design better"
+Type = "talk"
+Speakers = ["bodhanya-thameez"]
++++
+
+Infrastructure as Code has the great side-effect of allowing us to bucket our various types of infrastructure into tiers. These tiers may divide the infrastructure in many different ways (perhaps in terms of ownership, security level, or even frequency of change). Each tier may then be treated as a distinct unit, with each tier building upon the previous, to create a cohesive and coherent architecture design. This Talk will present a tried and tested tiering approach, which allowed us to improve our security posture, reduce IaC deployment times, reduce infrastructure sprawl, and enforce ownership; whilst giving greater freedom to our development teams to create required infrastructure quicker and safer.

+
+As organizations grow, Terraform codebases often grow with them—across teams, environments, accounts, and regions. What begins as a clean and modular setup can quickly become difficult to manage, duplicate, and evolve. This talk explores how to design an evolutionary Infrastructure as Code (IaC) architecture that scales without sacrificing clarity or autonomy. Using Terramate as an orchestration and structuring layer, we will examine practical patterns for organizing Terraform stacks, managing dependencies, and enabling multi-environment consistency.

+This talk explores a fundamental shift: treating the internal platform not as an infrastructure tool, but as a product with users, outcomes, and measurable success criteria. By reframing the platform around developer experience, feedback loops, and value-driven metrics, organizations can move beyond simple self-service and toward sustainable adoption. We will discuss how to identify signals of success and failure, align technical capabilities with strategic objectives, and evolve a platform into a continuously improving ecosystem. The result is a platform that developers trust, leadership supports, and the business can measure.

++++
+
+I have an M.Sc. in civil engineering. And then I switched paths, and have been a Be developer and manager for 20 years, before becoming a devops engineer group lead. While giving an enrichment session on concrete at work, I suddenly noticed that there are takeaways that can be taken from concrete's behaviour, to challenge managerial concepts. You need to water the concrete during the drying process - which means going against basic logic or intuition to get something better at the end. Concrete's tensile strength is only a 10th of it's compression strength, showing that when we insist on challenging someone who is extremely proficient in a specific area, "outside of their comfort zone", we might get very disappointing results. In addition there are more examples - we use steel to stengthen concrete as they have the same thermic coefficient of expansion, so they both contract and expand the same way in relation to the weather, we need teams to have priorities aligned or the group won't hold the pressure... We use steel to strengththen concrete as both oncrete and steel contract and expand the same way when temperatures change - the same way you want your team to have priorities aligned so that things work. In addition, 2 more concepts, of cutting out concrete "below the fold" (I and T beams) to reduce material which not only doesn't help support the beam but also increases the load to carry (=team members who don't do there part and we think "at least they cause no harm"), and pre stressed concrete.

+AI is writing more and more of our code - but when vulnerabilities ship, the responsibility still sits with us. Secure code review isn’t disappearing in the age of AI. It’s becoming a core accountability layer. Faster code generation means more assumptions, more hidden risk, and a greater need for engineers who can actually reason about security. In this interactive talk, we’ll explore why secure code review matters more than ever and sharpen those skills together through a hands-on, real-world review puzzle.
