Close an AWS Account Belonging to an Organization

Opening an AWS account is very easy to do. AWS makes it possible to create an account with an email address and a credit card. Even better, if you’re setting up a multi-account structure, you can use the API through organizations and you really only need an email address as an input. But closing an account is slightly more difficult. While closing accounts doesn’t happen quite as often as opening new ones, it does happen. Especially if you’re trying to fail fast and have made some organizational mistakes. When you want to clean those accounts up, you’ll need to jump through a couple of small hoops to do so. This post hopes to outline how to remove an account from an AWS Organization and then close it. ...

Create AWS Accounts with CloudFormation

In a previous post, we covered how to use an AWS Custom Resource in a CloudFormation template to deploy a very basic Lambda function. To expand upon this ability, lets use this knowledge to deploy something more useful than a basic Lambda function. How about we use it to create an AWS account? To my knowledge, the only way to create a new AWS account is to use the CLI or manually through the console. How about we use a custom resource to deploy a new account for us in our AWS Organization? Once this ability is available in a CloudFormation template, we could even publish it in the AWS Service Catalog and give our users an account vending machine capability. ...

AWS Custom Resources

We love to use AWS CloudFormation to deploy our environments. Its like configuration management for our AWS infrastructure in the sense that we write a desired state as code and apply it to our environment. But sometimes, there are tasks that we want to complete that aren’t part of CloudFormation. For instance, what if we wanted to use CloudFormation to deploy a new account which needs to be done through the CLI, or if we need to return some information to our CloudFormation template before deploying it? Luckily for us we can use a Custom Resource to achieve our goals. This post shows how you can use CloudFormation with a Custom Resource to execute a very basic Lambda function as part of a deployment. ...

Add AWS Web Application Firewall to Protect your Apps

Some things change when you move to the cloud, but other things are very much the same. Like protecting your resources from outside threats. There are always no-gooders out there trying to steal data, or cause mayhem like in those Allstate commercials. Our first defense should be well written applications, requiring authentication, etc and with AWS we make sure we’re setting up security groups to limit our access to those resources. How about an extra level of protection from a Web Application Firewall. AWS WAF allows us to leverage some extra protections at the edge to protect us from those bad guys/girls. ...

Using AWS CodeDeploy to Push New Versions of your Application

Getting new code onto our servers can be done in a myriad of ways these days. Configuration management tools can pull down new code, pipelines can run scripts across our fleets, or we could run around with a USB stick for the rest of our lives. With container based apps, serverless functions, and immutable infrastructure, we’ve changed this conversation quite a bit as well. But what about a plain old server that needs a new version of code deployed on it? AWS CodeDeploy can help us to manage our software versions and rollbacks so that we have a consistent method to update our apps across multiple instances. This post will demonstrate how to get started with AWS CodeDeploy so that you can manage the deployment of new versions of your apps. ...

How to Setup Amazon EKS with Mac Client

We love Kubernetes. It’s becoming a critical platform for us to manage our containers, but deploying Kubernetes clusters is pretty tedious. Luckily for us, cloud providers such as AWS are helping to take care of these tedious tasks so we can focus on what is more important to us, like building apps. This post shows how you can go from a basic AWS account to a Kubernetes cluster for you to deploy your applications. ...

Easy Snapshot Automation with Amazon Data Lifecycle Manager

Amazon has announced a new service that will help customers manage their EBS volume snapshots in a very simple manner. The Data Lifecycle Manager service lets you setup a schedule to snapshot any of your EBS volumes during a specified time window. In the past, AWS customers might need to come up with their own solution for snapshots or backups. Some apps moving to the cloud might not even need backups based on their deployment method and architectures. For everything else, we assume we’ll need to at least snapshot the EBS volumes that the EC2 instances are running on. Prior to the Data Lifecycle Manager, this could be accomplished through some fairly simple Lambda functions to snapshot volumes on a schedule. Now with the new service, there is a solution right in the EC2 console. ...

Should I use a Transit VPC in AWS?

A common question that comes up during AWS designs is, “Should I use a transit VPC?” The answer, like all good IT riddles is, “it depends.” There are a series of questions that you must ask yourself before deciding whether to use a Transit VPC or not. In this post, I’ll try to help formulate those questions so you can answer this question yourself. The Basics Before we can ask those tough questions, we first should answer the question, “What is a Transit VPC?” Well, a transit VPC acts as an intermediary for routing between two places. Just like a transit network bridges traffic between two networks, a transit VPC ferries traffic between two VPCs or perhaps your data center. ...

Who is Heptio?

There are a dozen new technologies being introduced every day that never amount to anything, while others move on to create completely new methodologies for how we interact with IT. Just like virtualization changed the way data centers operate, containers are changing how we interact with our applications and Kubernetes (K8s in short hand) seems to be a front runner in this space. However, with any new technology hitting the market, there is a bit of a lag before it takes off. People have to understand why it’s needed, who’s got the best solution, and how you can make it work with your own environment. Heptio is a startup company focusing on helping enterprises embrace Kubernetes through their open source tools and professional services. I’ve been hearing great things about Heptio, but when my good friend, Tim Carr, decided to go work for there, I decided that I better look into who they are, and figure out what he sees in their little startup. ...
