Amazon Web Services For Managers

I am often asked about the ins and outs of Amazon Web Services by C-levels, executives and managers. They’re not looking for the nitty gritty nuances of scripting and the Elastic Compute Cloud API, they just want to get an overview of how ‘the cloud’ works.

When explaining AWS for the first time to management (or anyone, for that matter) it’s best to speak conceptually rather than concretely. I have also found it beneficial to try to communicate in familiar terms. Using a term like “Elastic IP” seems curious, but calling it a publicly available IP address helps people understand the basics better before using the AWS term for things.

Hierarchical Organization

At the highest level, you can think of EC2 as a global computing environment. Within EC2 there are areas that can be thought of as data centers. Within these locations are computer groups that in AWS terms are called Availability Zones:

– EC2 (think: cloud)

—— Components (think: data center)

————– Access Points (think: computer group)

Standard Machines

Within the Availability Zone, we have the option to create virtual machines from Amazon Machine Images, or AMIs. AMI can be thought of as a virtual machine that you can pick up and run within the cloud on an On-Premise. Every time you download an AMI and run it, it is called an Instance of AMI. You can take an AMI and launch it multiple times, each time creating a new Instance.

Models are real machines running, and I mean real. If you’re not careful, this beautiful machine can weaken and cause a lot of confusion. So you don’t want to think of an Instance as something rigid and persistent. It’s just part of the inventory.

Virtual Hard Drives

To help keep your data immutable even if an Instance dies, you can use a number of different AWS services but one of the most popular is Elastic Block Store, or EBS. Think of EBS as a hard drive. You can create an EBS from 1GB to 1TB and ‘install’ it on any of your machines. So, if you have an Instance running your website and want to ensure that the database remains healthy even after the Instance is terminated, you can use an EBS ‘hard drive’. In AWS parlance, you created an EBS volume and mounted it on an Instance.

Other True Savings

There are other services that you could have used besides EBS to store your virtual database. For example, SimpleDB, or SDB, is a perfect replacement and may be preferred in some situations. However, SDB is a specialized database service, while EBS is a general storage system. There is also Relational Database Service, or RDS which provides more powerful databases than SDB. The choice of service is often based on the needs of the solution.

Virtual Backup

If we want to protect the data we have on our EBS volume, we are not out of the woods because even hard drives can fail. We would like to keep this as a permanent feature. For this we can use Simple Storage Method, or S3 for short. You can think of S3 as an easily accessible backup. It allows you to have 100 records on your tape. Each of these controls is called a container in the S3 world. Because it’s such a good permanent storage solution, you’ll want to back up your EBS volume to S3 from time to time. And, if you’ve customized your Instance, you’ll want to store the new image in S3. This way, if your Instance or EBS volume is damaged for any reason, you can get it out of your storage in S3 quickly and get up and running again.

Strong Defense

Well, all of this would be useless if we didn’t have good security to ensure that our solution was stolen. Two concepts are used in AWS for security purposes. The first is a key that allows you and your developers to gain access to your system. These are the public/private keys and digital certificate required to log into the Instance. The second, called the security group, can be thought of as a firewall configuration. You create a security group that defines how external entities – such as browsers, or remote desktops, or ftp, or email, etc. – can or cannot access your Instance.

Virtual Router

In order to serve our website to the public, we will need to have a static IP address that we can assign to our Instance. For this purpose we use Elastic IP, or EIP. It’s ‘hard’ because even though it’s a static IP, it can be assigned to any of our resources within AWS. This is a great addition because if the Instance dies and brings up a new Instance, we can move the EIP to the new Instance and reduce the page load.

Cloud Scalability

Our site is running on our own Instance, our data is securely stored on an EBS volume, we have backups on S3, access to our engineers, and our site is publicly available. All is well until we get traffic from anywhere else in the world. Obviously, our site is popular in areas that are far from the area where we set up our system. For example, we may have set up our website in the US, but we are getting 50% of our profits from Europe. The performance of our website for our European visitors is not as good as we would like. Fortunately, we can push our site closer to these users by using a Content Delivery Network, or CDN.

In AWS, CDN services are provided by CloudFront. This service takes your content and compares it to where you have the most users, resulting in faster rendering of your site.

The end

I hope this helps anyone who is interested in AWS and just needs a manager’s guide on how it works from a conceptual perspective. Please note that AWS is a constantly evolving system and new services and capabilities are added regularly.
