Amazon Web Services
Building a static site with Hugo, Terraform, and AWS
If you’re a frequent visitor to my blog, you may notice that it has a very new look as of today. This facelift isn’t just cosmetic or just related to any personal disclosures (although I’ll admit those played a role) - I’ve actually changed the framework that the blog runs on from Wordpress to Hugo as part of my exploration of serverless computing and web hosting.
Migrating services with zero downtime using EFS and lsyncd
Today, I want to talk about a situation that I found myself in recently. I have a production mail server that I had to migrate recently, as the OS version was getting quite out of date. Unfortunately, when I stood the server up, I didn’t plan on ever migrating - so I set everything up using local storage.
Lower your build costs with Jenkins and EC2 Spot Instances
Sometimes, a company may choose to avoid continuous integration due to the cost constraints of having a dedicated build server if working on-premises, or the high hourly cost of a powerful build server in the cloud. In a personal project I was working on recently, I ran right up against these cost constraints on a smaller scale - I didn’t want to wait forever for my builds to finish, but I also didn’t want to spend at a higher hourly rate to keep a build server up!
Amazon now allows IAM roles to be attached to existing EC2 instances
Just wanted to dash off a quick note. Amazon Web Services announced last week that you can now add IAM roles to your existing EC2 instances. This means you won’t have to recreate an instance in order to attach a role - now, you can use my tutorial on sending backups of your EC2-hosted data to S3 on instances you’ve already created, and not just new instances.
Creating S3 backups of EC2 data in the AWS cloud
As part of my switch over to the AWS cloud and specifically EC2 after my physical server started having issues, I wanted to make sure that I had reliable, consistent backups. Amazon provides a great solution for this in the form of Amazon S3, a service that provides eleven 9’s of durability for stored data.
A definitive Postfix/Dovecot mail server guide
My physical server finally bit the dust last month, so I finally took the opportunity to move up to the Amazon Web Services cloud. In the process of building my new cloud server, I realized I needed to get a mail server working - but I hadn’t ever built out a Linux mail server before past the very basics of configuring Postfix.
