vnet subnet sizing

One of the most overlook skills in cloud is designing or allocating subnet. Let's say your  vnet is created with address space of 10.0.0.0/16 - about 65,526 - we like to keep our VNET optimium with less fragmentations as possible. 

Here is a list that we can use to ensure we are able to size our subnet for different setup /29, /28, /27 and /26. This make our life easier. 

This would really depends on how your workload grows in a given subnet. For application that you would like to place them in a specific subnet and plan for certain expansion. If it grows beyond that, then you might need to provision a larger subnet.

There are 2 options to do this in Google  colab.  Option 1 (Easiest)  With this option, we can just install the relevant package and then run the model.  First we need to install the required packages using the following command:-  ! pip install -U llama-cpp-python Next,  we will try to get the model using the following command # !pip install llama-cpp-python from llama_cpp import Llama llm = Llama.from_pretrained(   repo_id= "unsloth/Qwen3-0.6B-GGUF" ,   filename= "Qwen3-0.6B-IQ4_NL.gguf" , ) We can see the model being downloaded:- And then we will run the following command to test this model llm.create_chat_completion(   messages = [     {       "role" : "user" ,       "content" : "What is the capital of France?"     }   ] ) And the output will look something like this:-  Option 2 llama.cpp is a powerful inference engine and if you wanted to get it running in google colab, you co...
