Modern telecom networks are increasingly deployed in the cloud. Running VoLTE load testing in AWS requires understanding both telecom protocols and cloud networking architecture. Here is a simplified breakdown of how a typical cloud-based telecom lab works. 🔹 Two Core Telecom Planes Control Plane (Signaling)• Protocols: SIP, Diameter• Handles registration, authentication, call setup• Typical…

DNS is the backbone of internet connectivity. When a user types a domain like www.example.com, DNS translates it into the IP address where the application is hosted. In cloud architectures, managed DNS services handle this resolution while also enabling advanced traffic management. Here’s a quick comparison of the three major cloud DNS services: 1️⃣ Amazon Route 53 — Best for advanced…

🚀 DPDK Nodes vs App Nodes in Telco Cloud (5G Kubernetes Deployments) In modern cloud-native telecom networks, workloads are split across DPDK nodes and application nodes to ensure performance, scalability, and predictable latency. 🔹 DPDK NodesBuilt for ultra-fast packet processing using Data Plane Development Kit.Typical workloads include the User Plane Function (UPF), packet gateways, and…

In standard Kubernetes, a pod gets only one hashtag#network hashtag#interface (hashtag#eth0).But telecom workloads like 5G hashtag#Core Network hashtag#Functions (hashtag#NFs) require multiple dedicated hashtag#interfaces for strict hashtag#traffic hashtag#separation.This is where Multus CNI becomes essential.🔹 hashtag#Without MultusOne interface handles management + signaling + user dataTraffic…

Karpenter is a Kubernetes cluster autoscaler. A NodePool is its primary configuration object that tells Karpenter what kind of nodes to provision and under what constraints.Key Sections Explained template.spec.nodeClassRef — Points to a cloud-provider-specific config (e.g. EC2NodeClass on AWS). That object holds AMI selection, subnets, security groups, instance profiles, etc. The NodePool stays…

You never update your SIM card manually. No app store. No USB cable. No reboot prompt. Yet your carrier pushes new configs, security patches, and features to it silently — while you’re on a call. That’s OTA (Over-The-Air) protocol doing work most engineers never think about. Let’s go from antenna to architecture. 🧠 PART 1: WHAT IS OTA AND WHY IT EXISTS OTA = delivering data, commands, or…
