Welcome to our Featured F5er Series. For July we are spotlighting momahdy, an exceptional contributor to our DevCentral community. DevCentral: To start, please introduce yourself and tell our community a little about yourself. What you do and why is it important? Mohamed: Hello everyone! My name is Mohamed Mahdy and I've been with F5 for the last 8 years, 4 of them in Consulting and the past 4 years in Technical Marketing team. Through the 8 years I covered different sectors whether Government, Defense, Services Providers, Financial or Education sectors. Why I got into security in general; I always loved learning everything, and one major part of our work involved understanding every deployment and project, not just the technical elements but the impact it leaves on every person involved. Few seconds delay, a breach or even a complex solution can be the difference between critical systems and efforts being protected or wasted. In addition to the actual work, I really enjoy educating the community because that's how I learn the best; The moment I meet a friend who says that he used any of the articles or any of our conversations and those were helpful, I feel the message is well delivered. Away from Work, I'm leading ISC2 chapter in West Midlands and participating in multiple community activities for security education. DevCentral: As a Principal Technical Marking Engineer at F5, what is your typical workday like? Mohamed: Big part of it connecting with my colleagues in Product team and field team to explore how can we get more end-to-end use cases to the community to help customers get familiar with the use cases and try them out. In some cases we are engaged with our colleagues in the field to help accelerate troubleshooting activities or solutions enhancement. One of the interesting areas of Technical Marketing Engineering team, is that we set at the cross roads between Technical and Business, that allows us to speak both languages and understand both; So, we help getting the end-to-end solutions use cases those actually help our customers and contribute to the field. DevCentral: What do you do to maintain a work life balance? Mohamed: Having great colleagues sometimes make work time feels like home, in addition to this I would say running and family time is what keeps the spark DevCentral: Can you give us a glimpse into your technical expertise? Mohamed: My approach is why not give it a try ? It's not working, let's roll up our sleeves. I started in Service Providers where packet captures solve your most critical issues, moving into F5 I got exposed to everything from L1 up to L7, whether it's a deployment, design or troubleshooting. F5 products are unique, you don't need to know F5 configurations only but also understanding the underlying protocols. DevCentral: What’s the most exciting thing you’re working on right now? Mohamed: Currently I'm focusing on BIG-IP Service Providers technologies and Kubernetes offerings (BNK / CNF / CIS ). Also leading the hybrid integrations with BIG-IP security products in general. I'm working on more articles to introduce those topics in an easy way to our community and make sure we are not lost in the new terms, and we are actually focusing on what works. DevCentral: What has been your most memorable achievement at F5? Mohamed: I would say every time a field colleague mention that any of the labs or articles helped I consider that a memorable moment. The most memorable one would be participating in AppWorld Vegas preparations. Seeing all those technical content in booths and customers talking and asking our SMEs after months of preparation, that was awesome. DevCentral: As an F5er who participates in the DevCentral community how has it helped or influenced your work? Mohamed: DevCentral community was special not just when I joined F5 but even before being part of F5; the ease of discussing solutions, raising queries and talking to peers in different industries in such community spirit really helped. DevCentral: Are there any challenges that community has helped you overcome? If so, what was it and how did community help? (Does not have to be DevCentral related) Mohamed: I would start with iRules, the other one would be learning to find different ways to deliver the information to suite different audiences. DevCentral: What does community mean to you? Mohamed: A group of diverse background persons crowdsourcing their knowledge to get the best outcome, the community acts as incubator for ideas DevCentral: What is your favorite or best piece of advice someone has given you? Mohamed: Security shouldn't be forced; Through my career I found this is the best advice, talking to the business and application teams to first understand their needs and then walk them through how security can be an enabler not a gate keeper proved to be the best approach. DevCentral: If you weren't in your current profession what would be your dream job? Mohamed: I would go for farming, I've been doing random trials here and there to plant mint and other plants, and I would say it's fun and very comforting DevCentral: What are your favorite or go to comfort foods? Mohamed: Yam yam yam! I would go for the Egyptian Koshari DevCentral: Now that we have entered summer, what are your favorite summer activities? Mohamed: I would say if I'm in Egypt, going to the sea at Marsa Matrouh. DevCentral: Lastly, what motivates you? Mohamed: New challenges, problems we need to find solutions for. Connect with Mohamed on LinkedIn Thank you Mohamed for all of your contributions to DevCentral and for being July's Featured F5er!
Announcing the first F5 NGINX Commercial Long-Term Support release
Today, we’re introducing a major change in how NGINX delivers software to enterprise customers: the first F5 NGINX Commercial Long-Term Support (LTS) release. Due to 2026's intensifying threat landscape, platform teams are under increasing pressure to keep critical infrastructure secure while minimizing operational disruption. Frequent upgrades, short support timelines, and constantly evolving features make that challenge harder than it needs to be. NGINX recognizes this burden. For the first time, NGINX customers can now choose: an annual, feature-frozen release with three years of guaranteed support, or the frequent updates they’ve always relied on to stay at the “cutting edge”. Why we introduced LTS Modern application environments, especially Kubernetes and API-driven platforms, demand both reliability and velocity. Until now, achieving that balance has often required trade-offs; frequent upgrades, shorter support windows, or unclear lifecycle expectations. The new NGINX LTS track eliminates those tradeoffs for production environments that value long-term stability. What is in the first LTS Release The inaugural NGINX LTS release launches with F5 NGINX Plus. F5 NGINX Ingress Controller. This is just the beginning-the LTS program is designed to grow, with more NGINX products joining in 2027. A clear support lifecycle model Each NGINX LTS release is supported for 36 months from General Availability and includes critical and high-security fixes, stability bug fixes, maintained third‑party dependencies, and full technical support. LTS releases are feature-frozen to protect production stability. Two Release Paths Long‑Term Support (LTS) Annual, feature‑frozen releases designed for production environments that demand stability. Each LTS release is supported for three years with security patches, stability fixes, and full technical support. Frequent Updates The release path customers have always known- delivering new features and improvements on a regular cadence throughout the year. Only the latest release is supported, and fixes are delivered by upgrading forward. Versioning Model The versioning format follows this structure: <product>.<major>.<minor>.<patch>.<package> Examples: LTS Patch Release: PLS.37.0.0.1 -> PLS.37.0.1.2 37.0 Stays the same since this is still the same LTS Patch increments 0 -> 1, a fix has been added Package increments 1 -> 2, a new build or image is produced Security Release: PLS.37.0.1.2 -> PLS.37.0.2.3 A critical CVE was identified Fixed delivered as another patch release Same LTS Release is used in this case Frequent Update Release: PLS.37.1.0.1 Continuous-release version Bump in minor versions showing new features added The next frequent release version would be 37.2.0.1 LTS (Major) Release PLS.37.0.0.1 -> PLS.38.0.0.1 Major increment 37 -> 38 New LTS Release Feature frozen at GA New 3 year support window Security without forced upgrades All supported LTS releases receive timely fixes for critical and high‑severity CVEs, without requiring customers to adopt new features or breaking changes. Easier planning Customers can standardize on LTS for production, adopt frequent updates for innovation, and align upgrades with annual planning cycles. Getting started You can begin using the first NGINX LTS release today by deploying LTS images and following updated installation and upgrade guidance in NGINX documentation. NGINX Long-Term Support (LTS) Our commitment NGINX LTS delivers enterprise‑grade predictability without slowing innovation. Customers can confidently standardize on LTS for production while continuing to adopt new capabilities on their own terms through continuous releases.AppWorld LATAM 2026 - "Write Your First iRule" Contest

The F5 AI Summit (June 23–25) is focused on one thing: what it takes to run AI in production without things falling apart. If you’re building or operating AI apps, expect practical sessions around the parts that usually cause problems—data flow, security, and scaling. Registration is free and if you follow DevCentral, you’ll be sure to see some familiar faces presenting! TL;DR Here are a few things you'll learn at the AI summit: How to design AI architectures that connect data, models, and traffic in a way that actually works at scale Where performance bottlenecks really live (hint: the data path, not just the model) How to secure AI systems with guardrails, policies, and continuous testing What it takes to scale inference—including GPU utilization and traffic control How to run AI on Kubernetes with routing, observability, and policy built in Agenda Highlights Here are details for some of the sessions you won't want to miss... especially the ones from rockstar DevCentral contributors! The Right Ecosystem for Secure AI Buu Lam will moderate a discussion with Ugur Tigli (CTO of MinIO) and Leon Derczynski (Principal Research Scientist at NVIDIA) to break down how cross-vendor architectures are shaping real-world AI deployments. Find out how integrating storage (MinIO), compute (NVIDIA), and application delivery/security layers enables faster data pipelines and more controlled inference flows. Get insights into AI data movement, system interoperability, and runtime security, especially how partnerships can help close gaps between infrastructure components. Reliability Between Compute and Storage Hunter Smit and Mark Menger walk through why data delivery is now the critical layer in AI infrastructure, especially as workloads shift from training to production inference. Learn how keeping pipelines efficient under load—covering how to optimize data paths so GPUs stay utilized and avoid idle time. See the role of application delivery controllers (ADCs) as a control point for storage traffic (including S3), acting as a front door for AI data movement. Delivering AI on Kubernetes: Model-Aware Routing and Traffic Control with NGINX Michael Kingston focuses on how to run AI workloads on Kubernetes with routing and traffic control designed specifically for inference workloads, highlitings capabilities like model-aware routing and policy enforcement, along with updates to NGINX Gateway Fabric and alignment with Gateway API standards. Get a practical look at how to add observability and control at the ingress layer, giving teams better visibility into AI traffic and more consistent behavior in production environments. See how to turn Kubernetes into a reliable control plane for AI inference. Conclusion Expect a more complete picture of the AI stack—from infrastructure and networking to security and runtime behavior. Registration is free! If you’re responsible for making AI systems reliable, fast, and secure in production, this will give you information you can actually apply.AppWorld Berlin 2026 – iRules Contest Winning Results
The second iRules Contest of the year wrapped up at AppWorld Berlin this week. This contest was looking towards the future, challenging participants to write an iRule that goes beyond BIG-IP’s built-in capabilities. The theme, using WebSockets or the Message Routing Framework, inspired iRules preventing abuse and intrusion. At the heart of it, we’ve loved the creative innovation of the iRules written for this years’ contests. The AppWorld Berlin iRules Contest submissions were inspiring. Across the board, judges’ feedback on the top contenders shared a common theme: these solutions are interesting. The winning iRules were well-documented, easy to understand, with clear potential value for production use. Without further ado, we’re proud to announce the winners of the AppWorld Berlin iRules Contest: Grand Prize Winner - Goerle_dev Rule: WS-Exfil-Shield: Catching What WAFs Miss After the 101 Handshake Summary This iRule addresses gaps in traditional WAFs by extending session-level, behavior-based threat detection to WebSocket traffic using real-time inspection within F5 BIG-IP. Detection operates in two stages; an initial timing-based heuristic is followed by payload validation using AI. Malicious actors are either blocked or routed to a honeypot for isolation and further observation. This iRule closes the gap that openly documented by major WAF vendors, post-handshake Websocket blind spot, with a practical, SIEM-ready enforcement. 2nd Place - Injeyan_Kostas Rule: WS-Shield: WebSocket Abuse Detection & Adaptive Enforcement Gateway Summary This iRule addresses securing WebSocket traffic by enabling real-time, behavior-based enforcement in F5 BIG-IP to proportionally mitigate abusive patterns without application changes. It introduces a behavioral enforcement engine designed to secure WebSocket traffic with adaptive, real-time mitigation without requiring application changes. Rather than relying on static thresholds, the system dynamically responds to behavior. Clean traffic naturally recovers, while abusive patterns escalate through enforcement tiers until they are cut off. This allows it to detect subtle, persistent attacks that traditional rate limiting often misses. In testing, the iRule identified and disconnected a bot sending repetitive payloads every half second, without triggering a rate threshold. The iRule adds an extensible, behavior-driven security layer that enables adaptable defenses with minimal investment, despite optional external dependencies. 3rd Place - Robb-Fr Rule: Generic iRule Based on Datagroup Parsing Summary This iRule addresses the complexity of migrating large numbers of Apache virtual hosts by centralizing flexible traffic routing and redirection logic within F5 BIG-IP using simple, extensible datagroups. It turns input into a simple form into a datagroup entry that CREATES iRULES for things like redirects, pools, error pages, rewrites, and more. This iRule is accessible to a wide range of F5 practitioners, as F5 expertise is not required. There are no direct iRule edits, and no way for them to break the device. This iRule lowers operational friction by enabling non-NetOps teams to manage complex traffic flows, improving agility during large-scale migrations.
