network design

Hey there, cloud burrowers! Bit the Chipmunk here, digging into one of the trickier corners of AWS networking: internal load balancers.

Many developers think “load balancer = public entry point.” But in real AWS environments, most load balancers never touch the internet — they live deep inside private networks, keeping traffic organized, secure, and scalable behind the scenes.

Hiya! Bit the Chipmunk here — your friendly AWS study buddy! Today we’re heading out to the edge — exploring how external load balancers connect users to your applications from the internet and beyond.

It’s me, Bit the Chipmunk! Let’s talk about one of the most visible parts of AWS DNS design — Route 53 Public Hosted Zones (PHZs). Public hosted zones are your go-to for making domain names resolvable on the public internet — whether you’re mapping a static website, an API endpoint, or a multi-region failover setup.

When the exam asks about public access, global availability, or internet-facing architectures, your chipmunk senses should start tingling for Route 53 Public Hosted Zones!

Hiya, folks! Bit the Chipmunk here — your bushy-tailed buddy for all things networking! Today we’re diving deep underground (like a good chipmunk) into the Private Hosted Zone, one of the trickier — but absolutely essential — Route 53 topics for the Advanced Networking exam.

Let’s get digging.

Hey there, network nut!

When you mix AWS networks with on-premises DNS systems, you need a way for the two to talk — securely, efficiently, and without breaking name resolution.

That’s where Route 53 Resolver Endpoints come in. They’re the bridge between AWS and external DNS systems, and understanding how to use them is critical for hybrid exam scenarios.

Hey squeak-mates! 🐿️ Bit here, digging into one of my favorite topics — how Route 53 helps manage global user traffic. But beware — not every “global” problem in AWS is solved with Route 53. Let’s learn where it shines… and where you should scurry away to another service!

Hey there, fellow cloud climbers! It’s your pal Bit, and today we’re scampering into the topic of domain registration — how AWS manages it through Route 53, and how it shows up on the Advanced Networking Specialty Exam.

While this might seem like a simple DNS task, the exam often sneaks in details about ownership, renewal, transfer, and validation, especially when domains are part of multi-account or hybrid DNS architectures.

Hey there, it’s Bit the Chipmunk, scurrying back into your study logs! We’ve already sniffed around the basics of DNS, health checks, and routing policies. Now let’s dig into how Amazon Route 53 plays nicely with other AWS networking services — because on the exam, you’ll often see questions that mix DNS and VPC design, hybrid connectivity, or edge routing together.

Hey there, cloud adventurers! 🏔️ It’s me, Bit the Chipmunk, your study buddy for AWS networking. Today we’re diving into how Route 53 handles private DNS — inside AWS, across accounts, across Regions, and even with your on-prem network.

Hiya, Bit here! Let’s take a quick scamper through how domain registration works — both in general and specifically within Amazon Route 53.

This topic may sound basic, but it’s a common foundation question on the exam, especially when evaluating public DNS architectures or troubleshooting domain resolution.
