Wrap It Up - Account Basics
In this section we discussed Account Basics. Now let's take a couple of minutes to review what we have learned and summarize the topics before we move on to the next section.
Identity and Access Management (IAM)
Introduction to AWS Identity and Access Management (IAM)
Welcome to AWS Identity and Access Management (IAM). Join us as we describe the lesson topics that will be covered in this section. For more on AWS IAM, see: https://aws.amazon.com/iam/faqs/?nc=sn&loc=5
What is IAM?
What is IAM and why would you use it? We answer these questions in our discussion about AWS Identity and Access Management.
IAM Initial Setup and Configuration
One of the first tasks that needs to be completed after creating a new AWS account is the initial setup and configuration of IAM. In this lesson, we'll complete five tasks that AWS recommends be completed on all new accounts. For more on Multi-Factor Authentication, see: https://aws.amazon.com/iam/details/mfa/
IAM Users and Policies
How do we give someone access to an AWS Service? We create an IAM user and attach a policy granting them access to it. In this lesson, we discuss how to create users and use a policy to grant them access. Note: AWS has introduced tag support with IAM. For more information, see: https://aws.amazon.com/blogs/security/simplify-granting-access-to-your-aws-resources-by-using-tags-on-aws-iam-users-and-roles/
IAM Groups and Policies
When large numbers of users need access to resources, it is much more efficient to give that access on a large scale, rather than granting privileges one at a time to individual users. In this lesson we'll see why using groups is the best way to do it, and walk through the process of assigning access policies to a group.
In addition to granting access to users and groups, there are times when we need to delegate access to users, applications, or services that need access to AWS resources. This lesson explains the difference between granting user/group access versus granting access to a service. For more on AWS IAM Roles, see: https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html https://aws.amazon.com/iam/details/manage-roles/
Wrap It Up - IAM Summary
It's time to wrap up IAM. Let's summarize what we learned in this section.
QUIZ: AWS IAM Essentials
Summary of AWS Network Services
Overview of Network Services
In this section we are going to discuss AWS services. Our discussion is going to include the AWS Global Infrastructure. We will also talk about AWS VPCs and the associated components including internet gateways, network access control lists, route tables, and subnets.
AWS Global Infrastructure
AWS maintains a world wide infrastructure. In this lesson, we will take a look at the AWS Global Infrastructure and describe how AWS services provide a highly available infrastructure through the use of regions and availability zones.
Virtual Private Cloud (VPC)
VPCs play an important role in the AWS architecture. A VPC is your private network within the AWS Infrastructure. Your AWS resources (such as EC2 instances and RDS databases) are deployed within a VPC. A VPC also provides internet connectivity for your AWS resources. In this lesson, we'll describe and discuss VPC basics.
Internet Gateways (IGW)
In this lesson we will discuss the role of internet gateways with VPCs, and describe how internet gateways are attached to a VPC to provide internet connectivity for provisioned AWS resources. For more information on AWS Internet Gateways, see: https://docs.aws.amazon.com/vpc/latest/userguide/VPC_Internet_Gateway.html
Route Tables (RTs)
A GPS tells you how to get from point A to point B. Within a VPC, a route table tells your data how to get from point A to point B. In this lesson we will describe route tables, and we will talk about how to create and modify route table entries. We'll also talk about how route tables are used to direct traffic to the internet via the internet gateway. Note: You can delete a route table if it has no associated subnets. You can't delete the main route table.
Network Access Control List (NACLs)
Security is a topic on everyone's mind. What can we do to proactively protect our computers from threats and vulnerabilities. One of the features used to protect your computer is a firewall. A firewall acts as a barrier for unauthorized communication to your computer. With a VPC, this firewall is called a Network Access Control List (NACL). In this lesson, we discuss NACLs and describe how to create rules to allow and deny traffic through the NACL.
Subnets are the location within a VPC where we store AWS resources, like EC2 instances and RDS databases. In this lesson we will discuss subnets and how they are used within a VPC.
Availability Zones (VPC Specific)
Availability Zones are used with AWS resources to provide redundancy and high availability within an AWS region. There are multiple availability zones within most regions. In this lesson we will look at how availability zones affect VPC high availability.
Wrap It Up - VPC Summary
It's time to Wrap Up VPCs. In this lesson we wrap up our discussion and summarize VPCs and the associated components.
QUIZ: VPC Essentials
Compute Services Overview
Summary of AWS Compute Services
AWS provides a variety of compute services. One of the most commonly used services is Elastic Compute Cloud (EC2). In this section we will discuss EC2, its components and features including Amazon Machine Images (AMIs), Security Groups, Instance Types, Security Groups and more.
Elastic Cloud Compute (EC2)
This lesson provides basic information about EC2. We'll compare an EC2 instance and its components to the basic components of a computer. We will also cover the most common purchasing options for EC2 Instances.
Amazon Machine Images (AMIs)
When setting up an EC2 Instance, we need to install an operating system, applications and configure settings. To simplify this process, we can use Amazon Machine Images (AMIs). AMIs are templates that contain an operating system, and are typically bundled with other applications and settings. We are going to talk about the different AMI categories, and components of an AMI.
An important part of setting up an EC2 instance is selecting the instance type. Instance types should be selected based on the application and workload requirements. In this lesson, we'll take a look at the instance types and associated components.
Elastic Block Storage (EBS)
EC2 instances require storage. One way to provide that storage is by using Elastic Block Storage (EBS). In this lesson we'll discuss EBS basics, including EBS root volumes, attaching and detaching EBS volumes, and snapshots.
Security groups provide virtual firewall protection for EC2 instances. Security groups protect EC2 instances by allowing and denying specific ports/traffic. They protect the instance, while network access control lists protect at the subnet level. In this video we will discuss security groups, and compare and contrast security groups against network access control lists (NACLs). Clarification: By default, a Default Security Group allows inbound traffic for only instances in the same security group.
EC2 instances can have private and public IP addresses. IP addresses are required for communication the internet. In this lesson, we'll discuss how IP addressing is applied to an EC2 instance, and compare the basic functionality of a private IP address vs a public IP address.
Launching and Using an EC2 Instance
It's time to provision an EC2 instance. We will utilize what we have learned so far in this section, and apply it them as we launch an EC2 instance. We will then connect to that instance using SSH and attempt to load an Apache web page. We will have to do a little troubleshooting to get everything to work properly. Note: If following along, just use the "Amazon Linux AMI (not the Amazon Linux 2 AMI). Here is the mini script used in the Advanced section when creating the EC2 instance: #!/bin/bash yum update -y yum install -y httpd service httpd start
Connecting to an EC2 Instance from a Windows PC
Connecting to an EC2 instance is a common AWS task. In working with AWS, we may be working with a variety of operating systems. In most lessons, we utilize Terminal on a Linux or Mac computer. In this lesson, we demonstrate how to connect via SSH from a Windows computer using the Putty application.
Wrap It Up - EC2 Summary
It's time to wrap up EC2. In this video we summarize all of the topics we covered in this EC2 section.
QUIZ: EC2 Essentials
Storage Services Overview
Summary of AWS Storage Services
Cloud data storage? Amazon Simple Storage Service (S3) is a bulk object storage service. In this section we are going to learn about S3 itself, and how to use it.
Amazon S3 is a bulk storage service for objects. In this lesson, we learn the basics of S3. We'll review a definition of S3, and look at some elementary but important configuraiton options that we'll need to configure when we store data on S3.
Buckets and Objects
Where does our data go when we upload it to Amazon S3? It is uploaded, as objects, into buckets folders. Let's talk about how these items will affect the data that you upload to S3.
Amazon S3 storage has a variety of characteristics that are based on Storage Class. For example, cost and object availability can vary by storage class. Let's compare the various storage classes, so we can understand the most cost effective and efficient way to store data. Note: For some new information on AWS Storage Classes, see: https://docs.aws.amazon.com/AmazonS3/latest/dev/storage-class-intro.html
Bulk storing objects on Amazon S3 Standard storage can become costly. We can automatically move data that is not critical or frequently accessed to different storage classes using lifecycles. In this lesson, we will learn how to transition objects between storage classes using lifecycles.
Trying to access an object on Amazon S3? Permissions are used to determine if access should be allowed or denied. Let's learn how to apply permissions to S3 buckets and objects. For updated information on setting S3 permissions, see: https://docs.aws.amazon.com/AmazonS3/latest/user-guide/set-permissions.html https://docs.aws.amazon.com/AmazonS3/latest/user-guide/block-public-access-bucket.html
Have you ever wished for a previous version of a file? With object versioning, you can keep multiple versions of the same file in an S3 bucket. Let's take a look at object versioning, and how it applies to buckets and the objects inside them.
Wrap It Up - S3 Summary
It's time to wrap up this section on Amazon S3. Let's talk about what we learned here.

Overview of Monitoring, Alerts, and Notifications
Summary of AWS Services for Monitoring, Alerts, and Notifications
Monitoring, alerts, and notifications services are all complementary parts of AWS products. It is often necessary to monitor AWS services, and to receive alerts and notifications when an event happens within the environment. Cloudwatch is what does the monitoring and creating of alerts. Amazon SNS is what sends out the notifications regarding those events and alerts. This notification application, Amazon SNS, is the first topic that we will cover.
Simple Notification Service (SNS)
How does Amazon SNS work, and what type of notifications can it send? We're going to cover SNS basics in this lesson, including the components of SNS. See https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html for the latest on SNS limits and restrictions.
How do Amazon SNS notifications work? SNS is a push service, and in this lesson we will learn what that means, and how SNS notifications get pushed to a topic. For more on SNS, see: https://docs.aws.amazon.com/sns/latest/dg/sns-getting-started.html
Wrap It Up - SNS Summary
It's time to wrap up our journey with Amazon SNS.

Elastic Load Balancer (ELB)
Introduction to Load Balancing, Elasticity and Scalability
Understanding how to optimize the compute environment is very important. In this lesson we introduce elasticity, load balancing, and scalability, and we kick it all off with this section about Elastic Load Balancer (ELB).
Too many people using your application or website is a good problem to have. How do we handle all of that traffic? Well, one way to manage it is by balancing the load across multiple servers (EC2 instances). In this lesson, we're going to meet Elastic Load Balancers and some associated concepts. For more on ELBs, see: https://docs.aws.amazon.com/elasticloadbalancing/latest/userguide/what-is-load-balancing.html https://aws.amazon.com/elasticloadbalancing/sla/
Creating an ELB
Let's walk through the process of creating an Elastic Load Balancer.

Note: For information on ELB SLAs, see: https://aws.amazon.com/elasticloadbalancing/sla/ For information on Error Codes and troubleshooting ELBs, see: https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-troubleshooting.html
QUIZ: ELB Essentials
Introduction to Auto Scaling
How do we respond to changing demand? During peak times we have a lot of traffic, but outside of those hours there is very little demand. How do we balance the two so that we don't unnecessarily pay for more resources than we need? The answer is Auto Scaling. Auto Scaling is elastic, meaning it can provision additional resources as necessary, and de-provision resources when they are no longer needed. In this video, we'll meet Auto Scaling, and have a look at what it can do.
Auto Scaling Basics
It stretches! It snaps back! It's elastic! It's auto scaling! Let's talk about the basics of Auto Scaling and see how it works.
Using Auto Scaling
Now that we've learned about Auto Scaling basics and learned about elasticity, let's walk through how to configure Auto Scaling components.
Wrap It Up - Auto Scaling Summary
It's time to wrap up our time with a summary of the whole Auto Scaling topic.
QUIZ: Auto Scaling Essentials
Introduction to Route 53
How does typing a website address into your browser get you to the server hosting the website's content? Domain Name System (DNS) and Route 53 work together to direct users to your website. In this video we introduce Route 53.
Route 53 Basics
In this lesson, we'll learn about Route 53 and the Domain Name Service (DNS).
Using Route 53
Let's put what we've learned into action! In this lesson we will walk through registering a domain, and creating alias records that point at the Elastic Load Balancer. Then we will load our new domain name and validate that our web page loads properly.
When users from all round the world are accessing an application or website, they can experience latency. CloudFront Content Delivery Network (CDN) replicates application and website data to locations around the world to reduce this latency, and give the users the fastest access possible to the data. In this lesson, we'll look at how CloudFront works with Route 53 and S3.
