MTU (Maximum Transmission Unit) is a critical networking parameter that defines the maximum size of a network packet that can be transmitted over a network interface. In general, larger MTUs can result in higher network performance by reducing the number of packets required to transmit a given amount of data. However, when network packets exceed the MTU of the underlying network infrastructure, they must be fragmented into smaller packets before transmission.

It is usual in the software teams, without regular code review sessions, that someone leaves the group and, over time that other services are ready to test, something doesn’t work after deployment.

I discovered an interesting open-source project today that has an entirely different approach from mine. Honestly, I couldn’t get along with it yet, but it might be in the near future I use it.

Do you have any ideas about creating your own AWS infrastructure, such as EC2s, ECS or etc. via PostgreSQL queries? This is the main idea of this open-source project: IaSQL.

There are many cases that might you need to have direct IP public address on your ECS task. When your tasks are on EC2, situation is a little easier, but if you are on Fargate, you need to do some tricks to get a reachable IP public.

gai.conf is a configuration file in Linux systems that controls the behavior of the getaddrinfo library function. This function is used to translate hostnames or IP addresses into socket addresses that are usable by various network protocols. By configuring gai.conf, you can specify the priority and order in which different address families (such as IPv4 and IPv6) are returned by the getaddrinfo function.
