Microservices Gone Wild – Tech Dive Part 2
In this post, I’ll outline the program I’ll be using to demonstrate how microservices work. It’s written in go but it’s pretty straightforward. At the end of the series of posts I will upload all of these examples to github as well, in case anybody wants to poke at them.
The Program – Squariply
For demonstration purposes, I’ll be discussing a very simple program that is currently implemented in a monolithic fashion. I’ve called it squariply
for reasons that will momentarily become obvious.
Purpose
Squariply accepts two integers on the command line, calculates the product (i.e. multiplies the two numbers), then squares the resulting number before printing the final result out. Mathematically speaking, if the integers provided on the command line are a and b, the output will be equivalent to (a * b) ^ 2.
Monolithic Code
My extremely amateur go code looks like this:
package main
import (
"fmt"
"os"
"strconv"
)
func main() {
str_a := os.Args[1]
str_b := os.Args[2]
int_a, _ := strconv.Atoi(str_a)
int_b, _ := strconv.Atoi(str_b)
multiplyResult := int_a * int_b
squareResult := multiplyResult * multiplyResult
fmt.Printf("Result is %d\n", squareResult)
}For the purposes of clarity, Continue reading
TCP Congestion Avoidance on Satellite Links
While some people spread misinformation others work hard to figure out how to make TCP work on exotic links with low bandwidth and one second RTT.
Ulrich Speidel published a highly interesting article on APNIC blog describing the challenges of satellite Internet access and the approach (network coded TCP) they took to avoid them.
