Multi environment logging with Serilog for AspNet Core Few months ago we saw how to get started with Serilog. We discovered what was Serilog and the different concepts of settings, enrichers and sinks. Today we will see how we can take Serilog further and configure a logging mechanism for an application running in multi environment. Setup Serilog Multi environment AWS CloudWatch 1. Setup Serilog If you have never seen Serilog before you can start with my previous post on How to get started with Serilog .

RollingFile sink also exists but it has been superseded with File sink. Next we can configure the logger to write to Console and write to a file: public static IWebHost BuildWebHost(string[] args) { return WebHost.CreateDefaultBuilder(args) ...

Estimating cloud infrastructure cost Few weeks ago I was tasked to estimate a cloud architecture with limited requirements. Today we will see the rules which can be followed in order to come up with a price tag. This post is composed by three parts: Defining the requirements Solution needs Price 1. Defining Requirements Before starting any estimation, it is important to get at least one requirement. In this example we will invent a scenario, really close to what I had irl, whereby we would be setting up a Christmas tree website with the following requirements. The trees are put to sale accross the whole year in advance We have about 50k purchases where 80% happens from November to December The most important aspect to remember is that estimates are estimates . It will never be exact, even if it happens to be exact, we probably got lucky. The goal of the estimates are to evaluate the magnitude of the price of an infrastructure whether the infrastructure would cost $100, $...
