Chapter 1. Introducing Amazon Web Services
Being in the IT industry, we all have gone through the long and tedious process of procuring new infrastructure for our data centers at one time or another. Let's be honest, it is not a task for the faint-hearted At a minimum, a brand new server can take weeks if not months to get delivered from its date of ordering, and this is too heavily dependent on a lot of external factors which, most of the time, are not in our control. Even if the new server comes in on time, there is the additional burden of prepping the rack, clearing space for the new resources, cabling, cooling, mounting, installation of software, configuration, and the list just keeps on going on for another mile. Putting the server and storage on one side, the same can also apply for networking, applications, software, and a whole lot of other things. But what if all this was to change? What if tomorrow, you could simply jump start your business or scale your application to thousands of servers, all with the simple click of a button? Seems farfetched, doesn't it, but in reality, this is possible today with a little help from something called as cloud computing.
Cloud computing has definitely evolved a lot over the years, and today it has become almost a mainstream part of our lives. Everything from storing large amounts of data, to having burst compute capacity at your fingertips and having enterprise software applications available on demand any time anywhere are just some of the key benefits that clouds provide today. At the helm of this new way of computing is Amazon Web Services (AWS).
In this chapter, we are going to look at some of the key features and benefits provided by cloud computing in general along with few interesting enterprise use cases. Later on, you will learn a bit more about Amazon Web Services and its core components, and finally have a look at how to sign up and get started with AWS.
What is cloud computing?
Cloud computing has become one of the most discussed topics over the last few years, but what does it actually mean? Why is it important for you and your business? Let's take a quick look at what cloud computing actually is and how you as an end user can benefit from it.
NIST defines cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (for example, networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. Was that a bit confusing? Let's break it down to understand it a little bit better:
Cloud computing features and benefits
Okay, so now we know what cloud computing really means, but why should you as an end user use it? How are you and your organization going to benefit from it? Let's look at some of the key benefits and features cloud computing has to offer:
This also reduces the overall maintenance costs as well. Since the organization now has less hardware to manage, it doesn't necessarily have to bother about its server, network, and storage capacity or have a full time staff to manage them.
Self-service: Cloud computing provides a simple, centralized, self-service-based model that end users can use to interact with the cloud platform. The interaction can be in terms of performing simple tasks, such as spinning up new compute resources, adding more storage resources at runtime, or more complex ones, such as scheduling resources and so on. This ensures that the end user can leverage and consume any of the cloud's resources on an on-demand basis.Faster time to markets: Unlike traditional IT, compute resources can be brought up in a cloud in a matter of minutes as compared to the weeks it used to take. This provides the end users with the ability to deploy new applications much faster, thus decreasing overall time to markets and reducing management overheads and costs.Scale as required: The best part of using the cloud is that your backend resources can grow as your application grows. This means that you are never lagging behind with your application's needs and demands, you are always scaling with your application's needs.Cloud computing use cases
With such features and benefits it is easy to see why there has been such a boom in the overall adoption and utilization of the cloud. Let's take a quick look at some interesting real-world use cases where your organization can leverage clouds:
Introducing Amazon Web Services
Now, that you clearly understand what cloud computing is all about and what it can do for you, let's get to know the main topic of this book—Amazon Web Services—a little better.
Amazon Web Services or AWS is a comprehensive public cloud computing platform that offers a variety of web-based products and services on an on-demand and pay-per-use basis. AWS was earlier a part of the e-commerce giant Amazon.com, and it wasn't until 2006 that AWS became a separate entity of its own. Today, AWS operates globally with data centers located in USA, Europe, Brazil, Singapore, Japan, China, and Australia. AWS provides a variety of mechanisms, using which the end users can connect to and leverage its services, the most common form of interaction being the web-based dashboard also called as AWS Management Console.
So how does the whole thing work? Well, it is very easy to understand when you compare the way AWS works with a power and utilities company. AWS offers its customers certain services just as a power company would to its consumers. You as an end user simply consume the electricity without having to worry about the underlying necessities such as generator costs, cabling, and so on. At the end of the month, all you get is a bill based on your electricity consumption and that's it! In a similar way, AWS provides its products such as compute, storage, and networking all as a service, and you only have to pay for the amount of service that you use. No upfront costs or heavy investments whatsoever!
The other important thing worth mentioning here is that AWS allows organizations to use their own operating systems, databases, and programming/architecting models as well, without requiring any major re-engineering. This provides a lot of flexibility and cost optimization to organizations as they get to operate and work with platforms that they are familiar with. This, accompanied with AWS's massively scalable and highly available infrastructure, ensures that your applications and data remain secure and available for use no matter what.
AWS architecture and components
Before we begin with the actual signup process, it is important to take a look at some of the key architecture and core components of services offered by AWS.
Regions and availability zones
We do know that AWS is spread out globally and has its presence across USA, Europe, Asia, Australia, and so on. Each of these areas is termed as a region. AWS currently has about 10 regions, each containing multiple data centers within themselves. So what's with all these regions and why do they matter? In simple terms, the resources that are geographically close to your organization are served much faster! For example, an organization running predominantly from USA can leverage the USA's regions to host their resources and gain access to them must faster.
For most of the AWS services that you use, you will be prompted to select a region in which you want to deploy the service. Each region is completely isolated from the other and runs independently as well.
Note
AWS does not replicate resources across regions automatically. It is up to the end user to set up the replication process.
A list of regions and their corresponding codes is provided here for your reference. The code is basically how AWS refers to its multiple regions:
Region
Name
Code
North America
US East (N. Virginia)
us-east-1
US West (N. California)
us-west-1
US West (Oregon)
us-west-2
South America
Sao Paulo
sa-east-1
Europe
EU (Frankfurt)
eu-central-1
EU (Ireland)
eu-west-1
Asia
Asia Pacific (Tokyo)
ap-northeast-1
Asia Pacific (Singapore)
ap-southeast-1
Asia Pacific (Sydney)
ap-southeast-2
Asia Pacific (Beijing)
cn-north-1
Each region is split up into one or more Availability Zones (AZs) and pronounced as A-Zees. An A Z is an isolated location inside a region. AZs within a particular region connect to other AZs via low-latency links. What do these AZs contain? Well, ideally they are made up of one or more physical data centers that host AWS services on them. Just as with regions, even AZs have corresponding codes to identify them, generally they are regional names followed by a numerical value. For example, if you select and use us-east-1, which is the North Virginia region, then it would have AZs listed as us-east-1b, us-east-1c, us-east-1d, and so on:
AZs are very important from a design and deployment point of view. Being data centers, they are more than capable of failure and downtime, so it is always good practice to distribute your resources across multiple AZs and design your applications such that they can remain available even if one AZ goes completely offline.
An important point to note here is that AWS will always provide the services and products to you as a customer; however, it is your duty to design and distribute your applications so that they do not suffer any potential outages or failures.
RULE OF THUMB: Design for failure and nothing will fail! This is what we will be sticking with for the remainder of this book as we go along the different AWS services and products; so keep this in mind, always!
Note
AWS provides a health dashboard of all its services running across each of the regions. You can view the current status and availability of each AWS service by visiting the following link: http://status.aws.amazon.com/.
AWS platform overview
The AWS platform consists of a variety of services that you can use either in isolation or in combination based on your organization's needs. This section will introduce you to some of the most commonly used services as well as some newly launched ones. To begin with, let's divide the services into three major classes:
Let's take a quick look at some of the key services provided by AWS. However, do note that this is not an exhaustive list:
We will discuss each of the foundation services.
Compute
This includes the following services:
Storage
This includes the following services:
Databases
This includes the following services:
Networking
This includes the following services:
These are just few of the most commonly used AWS foundational services that we listed out here. There are a lot more services and products that you can leverage to add functionality or use to manage your applications. A few of these important services are briefly described in the next section.
Distributed computing and analytics
This includes the following services:
Content distribution and delivery
Amazon CloudFront is basically a content delivery web service that can be used to distribute various types of content, such as media, files, and so on, with high data transfer speeds to end users globally. You can use CloudFront in conjunction with other AWS services such as EC2 and ELB as well.
Workflow and messaging
This includes the following services:
Monitoring
Amazon CloudWatch is a monitoring tool provided by AWS that you can use to monitor any and all aspects of your AWS environment, from EC2 instances to your RDS services to the load on your ELBs, and so on. You can even create your own metrics, set thresholds, create alarms, and a whole lot of other activities as well.
Identity and access management
AWS provides a rich set of tools and services to secure and control your infrastructure on the cloud. The most important and commonly used service for this is identity and access management (IAM). Using IAM, you can, as an organizational administrator, create and manage users, assign them specific roles and permissions, and manage active directory federations as well. We will be using a lot of IAM in the next chapter, which covers this topic in greater depth.
Getting started with AWS
So far, you have learned a lot about AWS, its architecture, and core components. Now, let's get started with the fun part—the signup process.
For all first time users, signing up for AWS is a very simple and straightforward process. We will go through this shortly, but first let's take a quick look at something called as a Free Tier! Yes, you heard it right… FREE!
So, AWS basically offers usage of certain of its products at no charge for a period of 12 months from the date of the actual signup. A brief list of a few products along with their description is listed here for your reference. Note that some of the description text may not make much sense now, but that's ok as this is just for your reference, and we will be bringing this up from time to time as we progress through the book.

Note
For a complete insight into the free tier usage, check http://aws.amazon.com/free/.
Awesome! So when we have free stuff for us right from the word go, why wait? Let's sign up for AWS. To begin with, launch your favorite web browser and type in the following URL in the address bar: http://aws.amazon.com/.
You should see the AWS landing page similar to one shown here. Here, select either the Create an AWS Account option or the Create a Free Account option to get started:
The next screen will help you with the initial signup process. Provide a suitable e-mail address or your contact number in the E-mail or mobile number field. Select the I am a new user option and select the Sign in using our secure server button to proceed:
Note
You can alternatively sign in using your Amazon.com credentials as well; however, its best to use separate credentials for working with AWS.
The next couple of screens will be used to provide your basic details along with the billing information. In the Login Credentials page, enter your Name, your E-mail address along with a suitable Password. This password will be used by you to login to the AWS Management Console, so ideally provide a strong password here. Click on Create account when done.
The next screen is the Contact Information page. Provide your FullName, CompanyName, Country, Address, City, PostalCode, and PhoneNumber as requested. Check the Amazon Internet Service Pvt. Ltd. Customer Agreement checkbox and select the Create Account and continue options.
Enter a suitable Cardholder's Name and your Credit/Debit Card Number in the PaymentInformation page as shown:
The last part of the signup process is the IdentityVerification process where you will receive an automated call from AWS as a part of the verification process. You will have to enter the displayed four digit PINcode on your telephone's keypad during the call. Once the verification is completed, you can click on the Continue to select your Support Plan tab:
The final step in the signup process involves the selection of the Support Plan. AWS provides four support options to customers, each having their own SLAs and costs associated with it. Here is a quick look at the support plans provided by AWS:
Note
The Basic Support plan is free of charge and all customers are entitled to it.
In our case, we opted to go with BasicSupport for the time being. You can change the support levels later on as well according to your needs. Click on Continue to complete the signup process. You should receive a couple of e-mails on your supplied e-mail address as well. These are introductory e-mails that will provide you with important links such as how to get started with AWS, billing page, account information, and so on.
With these steps completed, you are now ready to sign in to the AWS Management Console!
Introducing the AWS Management Console
So here we are, all ready to get started with the AWS Management Console! This is the most commonly used method to access, manage, and work with AWS services. We shall be looking more closely at the different AWS access mechanisms in the next chapter; however for now, let's quickly look at what the AWS Management Console is all about.
First off, sign in to the Management Console by launching your favorite browser and typing in http://aws.amazon.com. Click on the Sign in to the Console option and provide your EmailAddress and password as set during our signup process. Once you sign in, you will be welcomed to the AWS Management Console main landing page as shown here. Wow! That's a lot of products and services, right? The products are classified into their main classes such as compute, storage and content delivery, administration and security, and so on so forth. Take a moment and just browse through the dashboard. Get a good feel for it.
Navigating through the dashboard is also pretty straightforward. Let's look at the top navigation bar first. To the right-hand side you should be able to see three drop-down menus. The first should display your name as an end user. This option consists of three submenus that will help you with configuring your account details, security credentials, and billing management. The next tab lists the Region from where you will currently be operating. In our case, we have been placed in the US West (Oregon) region. Remember you can change these regions as and when you require, so feel free to change as per your current global presence:
Note
The US East (North Virginia) region is the cheapest region in AWS as it was one of the first regions to get set up and started.
The final tab in the list is the Support tab, and you can use it to login to the SupportCenter, AWSForums, and view the latest set of AWSDocumentation as well. Moving to the left-hand side of the tool bar, you will see four main icons listed there. Among these is a HomeScreen icon, which when clicked on will bring you back to the AWS dashboard screen irrespective of where you currently are.
The next drop-down option in the list is named as AWS, but what it really contains is called as ResourceGroups. These are a collection of AWS resources that can be organized and viewed as per your requirements. Think of these resource groups as a customized console where you as an end user can view all your required information about various AWS services in a single pane. How do resource groups work? Don't worry. We will be looking into this in more detail in the upcoming chapter.
Adjoining the Resource Groups is the Services tab, which lists the AWS services according to their class. It also has a history option that can be used to list and view your recently used AWS services.
The final tab is the Edit tab. This tab is used to customize your toolbar by filling it with those AWS services that you use frequently, kind of like a quick access bar. To add a particular AWS service to the toolbar, simply select the AWS service, drag and place it on the toolbar:
You can add multiple services as you see fit, and arrange them according to your needs as well. To save the changes to the toolbar, simply select the Edit option once again. You should see your AWS services listed out on the toolbar now. Feel free to dig around and check out the various options under each menu.
Getting started with AWS CLI
Now that you have a hang of the AWS Management Console, this would be a good time to take a quick look at the AWS CLI as well. Yes, you heard it right, apart from the standard web user interface, AWS provides a host of other mechanisms as well to help you gain access and use the various AWS resources. But why use a CLI in the first place? Isn't the AWS Management Console more than enough? Well, no. CLIs are more than just simple access and management tools. Using CLIs, you can automate the deployment and management of your AWS services using simple code and script, much like how you would use bash and shell scripting. This provides you with a lot of flexibility and customizability that a standard GUI simply won't provide!
The AWS CLI can be either installed on a Windows or a Linux machine. In case of Windows, AWS provides an easy-to-use installer, which can be downloaded directly from the AWS site. Once downloaded, all you need to do is run the installer, and voila, your Windows server should have the CLI installed and ready for use. But I'm not a Windows guy, so we will be walking you through the installation procedure on a standard Linux system.
Note
The 64-bit AWS CLI installer for Windows can be downloaded from https://s3.amazonaws.com/aws-cli/AWSCLI64.msi. The 32-bit installer can be downloaded from https://s3.amazonaws.com/aws-cli/AWSCLI32.msi.
In this case, we will be installing the AWS CLI on a CentOS 6.5 64-bit OS. The Linux distribution can be anything, from a Debian such as Ubuntu to a RedHat system; so long as it has Python installed and running off the latest version.
Note
Python versions supported are Python 2 version 2.6.5 and above or Python 3 version 3.3 and above.
You will also need sudo or root privileges to install and execute the commands, so make sure you have an appropriate user already created on your Linux system.
The installation of the CLI involves two major steps; the first involves the installation of Python setuptools, which is a prerequisite of installing Python's pip.
Run the following commands from your Linux terminal:
The following is the screenshot of preceding commands of the install process:
This completes the first part of the install process. The next process is very simple as well. We now install the Python pip package. Python pip is generally recommended when installing Python packages.
Run the following commands from your Linux terminal to install the Python pip package:
Refer to the following screenshot showing the output of the installation process:
Simple, wasn't it! You can test your AWS CLI by executing few simple commands, for example, check the AWS CLI version using the following command:That's just for starters! There is a whole lot more that you can achieve with the AWS CLI, and we will make sure to utilize it in each of our chapters, just to get a good feel for it.
