In this Session, I will explain and showcase - Diagnostic Settings Architecture for IaC.

Diagnostic Settings Architecture for IaC:-
Greetings to my fellow Technology Advocates and Specialists.
In this Session, I will explain and showcase - Diagnostic Settings Architecture for IaC.

| From the below code repository, please download the excel sheet named "Azure-Diagonostic-Settings-Architecture-v1.0.xlsx" which details the Diagnostic settings of each Azure Services, I have worked upon and the destination where it should be shipped to. |

Each Azure Services may or may not have Diagnostic settings. Diagnostic settings indicates that which logs will be shipped to which destination.
| WHY DIAGNOSTIC SETTINGS ARCHITECTURE IS IMPORTANT:- |

POINTERS |
| 1. |
Logs can be related to Infrastructure, Application, Database and Security. So Proper segregation is required for daily operations. |

Each Azure Services may or may not have Diagnostic settings. Diagnostic settings indicates that which logs will be shipped to which destination.
| WHY DIAGNOSTIC SETTINGS ARCHITECTURE IS IMPORTANT:- |
| # |
POINTERS |
| 1. |
Logs can be related to Infrastructure, Application, Database and Security. So Proper segregation is required for daily operations. |
| 2. |
If all logs are pushed to same Log Analytics workspace, we cannot bifurcate the cost per domain/application. |
| 3. |
A clear definition will help establish, as which logs, we want to push to log Analytics and which one, we would like to archive in Storage Account as Log Analytics can be very expensive very fast if not defined properly. |
| 4. |
This clear definition can then be replicated for all projects to keep it consistent organisation wide (We all know it is always not possible but to the extent we can :-)) which can eventually become one of the best practices. |
| 5. |
This definition can then serve as a blueprint for IaC (Infra-As-Code). |
| WHERE LOGS CAN BE SHIPPED:- |
| 1. Send to Log Analytics workspace. |
| 2. Archive to a storage account. |
| 3. Stream to an event hub. |
Below table indicates the list of Azure Services for which this Diagnostic Settings Architecture is applicable.

You will be surprised to know that there are a lot of Azure Services which DOES NOT have Diagnostic Settings option.
