Why KEDA Matters: The Missing Piece in Kubernetes Autoscaling for Critical Customer Applications
Devops.dev is a community of DevOps enthusiasts sharing insight, stories, and the latest development in the field. Press enter or click to view image in full size Introduction Over the past few years, Kubernetes has become the de facto platform for running mission-critical applications. This is especially true in banking, fintech, e-commerce, and other industries that serve customers around the clock.
The Hidden Cost of Cheap Kubernetes Nodes - Complete Advanced Analysis with Real Metrics, Case Studies, and Excel Template
I really like Kubernetes, in the world of Kubernetes, the common assumption that cheaper nodes equal lower costs often leads teams to an unexpected paradox: the cheaper the node, the higher the bill. While smaller instances may seem economical at first glance, they can quietly inflate overall cluster expenses through hidden inefficiencies in pod density, networking limits, and control-plane overhead.
Shannon’s Principle in IoT: Lessons from the Field
When we talk about IoT, three elements always come to mind: the platform (web and mobile apps), connectivity, and the device. This already shows how complex IoT can be — security, data transmission, databases, analytics, and more all have to be considered. One of the most common problems in IoT boils down to three critical factors: Battery life (devices must last years, not months), Low cost (solutions must be scalable), and Reliability (devices must work even in difficult environments).
FrontOps: From “It Works on My Machine” to Owning Production
Imagine you’re the lead frontend engineer at a B2B SaaS company. Your React/Next.js dashboard is deployed globally via CDN. Life is good… until one Friday afternoon: customers complain: “Dashboard keeps spinning, nothing loads.” Support tickets explode. Backend graphs show no error spike. Everything “looks fine”. You check your local dev: everything works. You check staging: everything works. Production? In Chrome it works. In older Safari it doesn’t. And only for some regions.
Understanding Canary Rollouts: Strategies, Techniques, and Real-World Applications
Introduction I have experienced on one small project where I had to deploy what everyone called a “minor” feature update. The change looked small on paper: a tweak in the recommendation logic and a new parameter in one API. QA had tested it in staging, the build was green, and the pressure to release fast was high. We pushed it directly to production — no canary, no traffic split, just a full rollout. Within minutes, dashboards started to turn yellow, then red.
Limbah pabrik kelapa sawit dapat disulap jadi pangan bernilai gizi tinggi dan pupuk organik
Bandarlampung (ANTARA) - Limbah sawit ternyata bisa menjadi sumber pangan bernilai tinggi. Di tengah melimpahnya tandan kosong kelapa sawit (TKKS) yang sering dianggap tidak berguna, dan dibuang begitu saja, sebuah inovasi lahir dengan pemanfaatan TKKS sebagai media tanam jamur merang.
A Deep Dive into OTA Update Support with KubeEdge for Edge Kubernetes
I have always been deeply inspired by the orchestration capabilities of Kubernetes. Over the years, many of the digital platforms I have designed and built were intentionally directed toward Kubernetes as the backbone — though always with careful consideration of context, to avoid making it overkill where simpler solutions would suffice. That said, one area where Kubernetes reveals its true potential is in edge computing and IoT.
Search Engine vs Semantic Caching: A Comparative Analysis
Perhaps all of us have felt the frustration of trying to find a product on our favorite e-commerce site. In my experience, I once typed “cellphone holder” and got no results. But when I searched for “mobile stand”, suddenly dozens of relevant products appeared. This disconnect — between how users express what they need and how our systems store or retrieve it — prompted me to dive deep into optimizing our platform’s search experience.
Embracing Uncertainty: Probability Management in Project Execution
The assertion “Certainty is uncertainty itself” might initially appear to be a paradox. However, within the intricate landscape of project management, this statement resonates with profound truth. Project professionals frequently pursue definitive metrics — exact timelines, fixed budgets, and precise deliverables.
Handling PostgreSQL Connection Pooling
PostgreSQL: connection limit exceeded. PostgreSQL’s powerful features and reliability make it a preferred choice for modern applications. However, in serverless and microservice environments, managing PostgreSQL connections and resources is critical.
API Gateway vs ESB 101
In modern system architecture, particularly for enterprises and digital organizations, two key components are often used to manage and integrate services: API Gateway and Integration Platform (also known as ESB — Enterprise Service Bus). Although both are involved in the system communication flow, their focus, purpose, and architecture differ significantly.
In today’s fast-moving software landscape, selecting the right backend messaging and caching architecture is critical. With the rapid rise of new tools and platforms, especially those incubated under Cloud Native Computing Foundation (CNCF), it has become essential for architects and developers to benchmark technologies in-house before deciding on one.
Data Pipeline Filters 101: Choosing Between Static and Dynamic Approaches
M Mahdi Ramadhan, M. Si · Follow 6 min read · -- In data-driven world, managing and optimizing data pipelines is crucial for handling massive data volumes. Filtering, a core aspect of data processing, allows organizations to sift through vast datasets to extract valuable insights. However, choosing the right filtering approach can significantly impact the efficiency and flexibility of a data pipeline.
What Some Project Managers Forget: Beyond Task Completion to Strategic Vision
M Mahdi Ramadhan, M. Si · Follow 5 min read · -- In the world of project management, there’s a common misconception that success is measured solely by the completion of tasks and the timely delivery of projects. While these are undoubtedly essential aspects, focusing exclusively on finishing the project can leave a lot on the table.

Exploring Extreme Learning Machine: Fast and Simple Neural Network Training
Extreme Learning Machine (ELM) is a machine learning algorithm introduced by Guang-Bin Huang, Qin-Yu Zhu, and Chee-Kheong Siew in a seminal paper titled “Extreme Learning Machine: A New Learning Scheme of Feedforward Neural Networks” published in 2006. The ELM algorithm is designed to train single-hidden-layer feedforward neural networks (SLFNs) with extreme speed while maintaining good generalization performance.
