History
1994-2006
1994: Jeff Bezos founded Amazon
2002: AWS was developed for Amazon’s internal infrastructure
2003: AWS started building an "infrastructure service for the world.”
2006: Amazon launched “Amazon Simple Storage Service” (Amazon S3) and a virtual computing
environment called “Amazon Elastic Compute Cloud” (Amazon EC2)

How big is Amazon Web Services?
Today
About 1.4 million servers working around the globe
158k − 450k servers
1/3 of all internet users will access an AWS cloud site at least once a day (2012)
1% of all internet trafﬁc (2012)

Introduction
Marketing lines
Scale to your needs - Amazon EC2 provides re-sizable compute capacity which allows to quickly
scale capacity, both up and down, as your computing requirements change.
Pay per hour - Amazon EC2 allows you to pay only for capacity that you actually use.
Buttom line
EC2 instance is a remote
{server / machine / virtual machine / instance / computer / host }
with ﬂexible and changeable speciﬁcations.

Oh. Wait... Key pair? SSH?

Kay Pair and Asymmetric Cryptography
Public-key encryption
Public-key encryption and authentication
The “message“ is encrypted on the remote machine using the client’s public key
The “message” can be decrypted only with the matching private key
RSA is one example of a public-key algorithm. RSA is based on the practical difﬁculty of factoring the
product of two large prime numbers.

Secure Shell (SSH)
What is an SSH protocol?
Basics
A shell is a user interface for access to an operating system’s services
A Secure Shell (SSH) is an encrypted network protocol for initiating text-based shell sessions on
remote machines in a secure way
Client side requires SSH client (such as Putty or MobaXterm)
Remote side require SSH server (build-in Ubuntu server)
The Secure File Transfer Protocol (SFTP) is an SSH extension that provides file access, file transfer,
and file management functionalities
Usually, SSH uses port 22
SSH uses Asymmetric cryptography

Asymmetric cryptography
In practice
How? What? Where?
On the remote server there should be a list of authorized public keys. The corresponding private keys
are authorized for connection.
The authorized_keys file is located in
/home/<user_name>/.ssh/authorized_keys
To connect to the remote server, make sure that your public key appears in the authorized_keys file
(on the server)
Choose your private key file on the SSH client configurations
That’s it

Linux basics
Command line
The Linux command structure: command OPTIONS ARGUMENTS
Command: This is the base of the command.
To show top lines of a file, use the head command
To to create new directory use the mkdir command
OPTIONS: Alter the behavior of the command.
To show 5 or 10 top lines of a file, use the head command with option -n 5 or -n 10
ARGUMENTS: Typically file names or other data that is needed by the command.
head -n 5 file_name

Linux basics
Super User DO
First Thing to know:
sudo = Super User DO.
Example:
To delete the ﬁle ’a.txt’ type: rm a.txt
However, if it doesn’t work, try: sudo rm a.txt
Example:

Linux basics
List of files and directories:
ls, ls -l, ls -l dir_path.
Navigate between directories:
cd, cd .., cd ~, cd /, cd dir_name
Edit/create file (using nano or vim)
nano file_name.R, vim file_name.R
open file in view mode (read only)
nano -v file_name.R
Display Linux processes:
top, htop (sudo apt-get install htop)

Linux basics
Add user
ubuntu is the default AMI (Amazon Machine Image) user.
RStudio require password authenticated user.
Add user:
sudo adduser <username>
you will be asked for a new password (twice) and then for an optional additional information.
Make yourself a sudoer (optional):
sudo adduser <username> sudo

In Linux, like in R, we can download packages (≈software) from repositories.
For example, to install R run:
sudo apt-get install r-base-core
Download package lists from the repositories:
sudo apt-get update
Upgrade packages according to the updated information:
sudo apt-get upgrade
The default repositories install old R version (3.0.2), In order to download the latest version we need
to manually add repository.

Add repository and install latest R version
Edit the sources.list ﬁle and add the R repository location
sudo nano /etc/apt/sources.list
Add this line to the end of the ﬁle:
deb http://cran.rstudio.com/bin/linux/ubuntu trusty/ .
To get permissions to the new repository run:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 51716619E084DAB9
Download new package lists:
sudo apt-get update
Install the latest R version (3.2.0):
sudo apt-get install r-base-core

Only a few seconds away...
Rstudio installation
gdebi lets you install local deb packages:
sudo apt-get install gdebi-core
Download rstudio’s deb package:
wget http://download2.rstudio.org/rstudio-server-0.99.446-amd64.deb
Use gdebi to install the deb package:
sudo gdebi rstudio-server-0.99.446-amd64.deb

Only a few seconds away...
Rstudio installation
gdebi lets you install local deb packages:
sudo apt-get install gdebi-core
Download rstudio’s deb package:
wget http://download2.rstudio.org/rstudio-server-0.99.446-amd64.deb
Use gdebi to install the deb package:
sudo gdebi rstudio-server-0.99.446-amd64.deb
Open web browser and enter url: <server_ip>:8787
Use your username and password.
Do crazy things with Rstudio.
