Hello and welcome back to Going Serverless with AWS. In Part 2 we learned how to use Python with AWS Lambda to Register a user to our RDS instance. Today we will learn how to build an API Gateway an Register our users using a JQuery.
So lets get started!
Building our API Gateway What is API Gateway Amazon API Gateway is an AWS service that enables developers to create, publish, maintain, monitor, and secure APIs at any scale.

Hello and welcome back to Going Serverless with AWS, In part 1 we learned what Serverless means and what we are going to build. In part 2 We will learn how to create an RDS instance with the AWS cli tools, and build our first lambda function, package it, deploy it, and invoke it using the AWS cli tools.
In the spirit of keeping this as simple as possible you will be able to copy and paste all commands and get a working setup however this will be super insecure as passwords and things will be set using the AWS cli.

What is Serverless? Serverless architectures refer to applications that significantly depend on third-party services (knows as Backend as a Service or “BaaS”) or on custom code that’s run in ephemeral containers (Function as a Service or “FaaS”), the best known vendor host of which currently is AWS Lambda. By using these ideas, and by moving much behaviour to the front end, such architectures remove the need for the traditional ‘always on’ server system sitting behind an application.

Thanks for coming back for part 2 of my Chef Guide with Digital Ocean. In this part I will take you through setting up Chef with the Digital Ocean Gem and Bootstrapping your First VM. As a little bonus I will show you how to create a very simple cookbook to manage SSH Keys on your bootstrapped VM. If you have not already Done so remember to check out Part 1
The Digital Ocean Plugin
Setting Up the Plugin!
So now we have our chef server we should maybe put it to the test and bootstrap a new VM. To do this you will need to get the Digital Ocean plugin for knife.
As some of you may know I was recently DDoSed and Was Terminated by Linode for being flooded with 5.11MB/s of Traffic 3 times over a 5 day period. This left me looking for a new solution. I only had a ZNC Server and a couple of DNS Servers with them so it was no big Loss. (For DNS I now use AWS Route 53 its awesome) Any way in my search I came across DigitalOcean and must say I am very impressed with their Pricing, and no bullshit infrastructure. I thought while I was at it I would get better acquainted with chef as although I have used chef in the past I never setup my own chef server so decided to do so. I also found out how simple it is to bootstrap and run an SSD Cloud Instance on DigitalOcean with Chef.
Why would we do this? As far as I am concerned there is no legitimate use for this technique however it is a useful skill to possess and understand how a Buffer Overflow works. Understanding these concepts will help you develop more secure applications.
What is a “Buffer Overflow”? Well put simply a buffer overflow is an attack vector where you attack an application by overflowing the memory location of a buffer leading to code leaking into the next memory location. This usually causes a Segmentation Fault (SIGSEGV in linux). Using this we can execute arbitrary code or cause the application to execute another piece of code within the application by overwriting the return value.
Will this harm my computer? Using this guide will not harm your computer unless you do something terribly wrong. Feel free to use a virtual machine.
I decided to port this over from one of my Previous posts to give myself some content worth reading. Its a guide I wrote that walks you through the process of setting up MariaDB, NginX and PHP on CentOS 6. This is now the default “lamp” (I suppose its now LNMP) stack of EL7. Pre-Requisites : An EL6 Server (A VPS Will do) 15-20 Minutes of Spare Time
Initial Setup First we need to install the EPEL Package source.
