One more reminder that Slack is a terrible choice for communities, and extort even nonprofits. Even when it’s one teaching teens to code, for free.
Hack Club is moving to Mattermost. They really have no choice.
Just a poor taste how Slack demands $50K in a week, no real notice
My new AZ-700 course is out now. And everything is 25% off to celebrate. Use the code: OCTOISBACK.
☁️ Subnetting, routing, filtering
☁️ Load-balancing (regionally/globally)
☁️ Hybrid routing and connectivity
☁️ Firewalls, NVAs, VWANs

☎ No one wants angry customers calling up for an offline app. So load balancers are a great technology to understand.
If you’re interested in getting hands-on, I have courses at learn.cloudlee.io.
Azure has another product called Load Balancer also.
It distributes traffic to healthy instances and is a central access point for your users like App Gateway.
Unlike App Gateway, Load Balancer is not layer-7 aware.
More fundamentals you need? Load balancing. Because you want your solution to be highly available.
Why load balancers?
When hosting apps in the cloud, reduce risk of outages by hosting across duplicate infrastructure.
But then you need a central entry point.
Networking knowledge helps with cloud.
Here are some tips for Azure:
Generally there are services:
🔗 Built for public access
🔗 Built for private access
☁ Public services like App Service have public endpoints to host public solutions.
You can change this.
🔜 Want to dive deeper into Azure networking? I'll be starting work on the AZ-700 Azure Network Engineer course with my syllabus coming out soon (amongst more projects!).
👀 You can learn more about networking features like this in many of my Azure courses (it's critical to several roles). Check out learn.cloudlee.io or learn.cantrill.io if you're interested.
🔐 What if you only want to allow private access from a VNet?
For that, you can use Service Endpoints or Private Link to ensure that all network access is private via Microsoft’s backbone.
There’s a lot of tools/features for different scenarios.
E.g. you have a web app, and you only want it available to users in your head office.
Most Azure public services have built-in firewalls that allow you to configure network restrictions like this.
FYI Microsoft are changing exam pricing.
You can grab more information here: techcommunity.microsoft.com/t5/microsoft-l….
Pricing changes November 1 2024.
There are some decreases and increases.
E.g. for the Azure Architect cert, you must pass:
☁️ AZ-104 exam, and
☁️ AZ-305 exam
For the Azure DevOps cert, you must pass:
☁️ AZ-104 or AZ-204, and
☁️ AZ-400
If you’re looking for more guidance, I have courses at learn.cloudlee.io
One thing these resources don’t make clear is the difference between MS exams and certs.
For MS an exam and cert are two separate things. Sometimes passing one exam gives you a cert. Other times you need two exams to achieve one cert (like the expert certs).
Microsoft do exams and certs a bit different. Here’s some tips if you’re getting started.
Not sure what role to aim for? MS have a neat roadmap: aka.ms/traincertposter.
And if you are planning to get certified, they provide free practice tests: learn.microsoft.com/en-us/certific….
@ssikder21 Thanks that’s great to hear! I do have these courses in my course roadmap for consideration. You can vote here too: github.com/users/jamesdpl…. AZ-700 will be before SC-100 (which is still TBC).
