A curated list of AWS resources to prepare for the AWS Certifications

A curated list of awesome AWS resources you need to prepare for the all 5 AWS Certifications. This gist will include: open source repos, blogs & blogposts, ebooks, PDF, whitepapers, video courses, free lecture, slides, sample test and many other resources.

The information below was written in Oct 2017. In August 2019 AWS launched official support for multiple target groups per AWS ECS service. Please use that feature instead!

Unfortunately as of writing this (Oct 18, 2017) there is no built in integration for multiple target groups per AWS ECS service. Here are a few things you can try:

If your application just serves port 80 (HTTP) & port 443 (HTTPS) then you should consider using the application load balancer and terminating SSL at the load balancer. This will allow your application to function using just port 80.

So, whats wrong with the following start to a constructor of a Graph class?

public Graph(String fileName) {
    File file = null;
    try {
        file = new File(fileName);
    } catch (Exception e) {
        // TODO: handle exception
 }

Cloud Object Storage Abstraction Layer

Q: Shouldn't we name it like Cloud Agnostic Object Storage Interface

The Object Storage is one of the fundamental services provided by the cloud provides. The objects are generally stored in the tree directory structure similary like on the file system. The objects are consumed either by API or in most cases by their unique HTTP URL or by cloud specific internal URI (See Appendix 1).

Motivation

The initiative addresses a growing need to support the hybrid cloud applications by allowing the developers to transparently access and manipulate the objects from within applications running in various cloud environments.

	#!/usr/bin/python
	import subprocess
	import os
	import sys

	#res = subprocess.Popen(['ls','-al','/ahome'],stdout=subprocess.PIPE,stderr=subprocess.PIPE);
	#output,error = res.communicate()

	#if res.returncode:
	# #raise Exception(error)

	import java.io.IOException;
	import java.net.URLClassLoader;
	import java.nio.file.Files;
	import java.nio.file.Paths;
	import java.nio.file.Path;
