network design

Hey network adventurers! Bit here, squeaking from the treetops with my acorn of observability. Today we’re going deep on two powerful visibility tools in AWS: Flow Logs and Traffic Mirroring. If you’re preparing for the AWS Advanced Networking exam, you’ll want to know when to use each, what they show, and how they differ—especially when you’re managing hybrid or complex networks.

Hey there, cloud climber! 🧗‍♂️ Bit here, and today we’re looking at something every AWS networking pro must understand for the exam: how load balancers scale — and what can make them not scale when traffic spikes.

Load balancers seldom operate entirely on their own — they integrate with a host of other AWS services. Let's dive into the details on some of the most important integrations for the Advanced Networking Specialty exam!

Every AWS load balancer has knobs and dials that tune its behavior: how it routes traffic, maintains connections, and interacts with clients. These configuration options often show up in exam scenarios that test your ability to spot subtle performance or architecture trade-offs.

Hey there, network navigators! Bit the Chipmunk here — ready to scamper through one of AWS’s trickier (but super important!) topics: how target groups and listeners work across different types of load balancers. ⚙️🌐

If you’re studying for the AWS Advanced Networking – Specialty Exam, this one’s a must. The exam loves to throw scenarios that hinge on whether you understand how each load balancer listens for requests and where it sends them.

Hey there, cloud critters! Bit the Chipmunk here, ready to scurry into the intersection of Kubernetes and AWS networking — one of the exam’s sneakiest acorns: the AWS Load Balancer Controller (LBC)! 🐾⚙️

If your exam question mentions EKS, Ingress, or Service of type LoadBalancer, this is your signal to think:

“Aha — that’s the AWS Load Balancer Controller at work!”

Let’s dig into how it works and how to spot the right pattern under exam pressure. 🌰

Hey cloud explorers — Bit the Chipmunk here! 🐿️ Today we’re nibbling into one of the juiciest nuts in the exam forest: encryption and authentication patterns for AWS load balancers.

You’ll see words like TLS termination, mTLS, ACM, and inspection scattered all over exam questions. They’re testing whether you know where encryption happens, who owns the certs, and what visibility each pattern gives you. So, let’s break it down clearly — no crumbs left behind!

Hey cloud explorers — Bit the Chipmunk here! When an exam question asks “Which load balancer should we use?”, your job is to map requirements → constraints → the right LB. This article gives you the decision patterns, quick rules, and exam clues to choose ALB, NLB, or GWLB (and when to combine them).

Hiya, it’s Bit the Chipmunk again! Today we’re diving into one of my favorite topics — load balancing — the art of keeping traffic happy, healthy, and evenly spread out across multiple servers.

Load balancing is all about distributing traffic to improve availability, scalability, and sometimes even security. But not all load balancers are created equal — each layer of the OSI model adds its own flavor of smarts.

When your app grows busier than a chipmunk in acorn season, you need a way to spread the traffic around — evenly, securely, and without hiccups. That’s where AWS load balancers come in. They’re not one-size-fits-all — each is tuned for specific layers, traffic patterns, and resilience needs.
