Screaming in the Cloud
Episode 2: Shoving a SAN into us-east-1
When companies migrate to the Cloud, they are literally changing how they do everything in their IT department. If lots of customers exclusively rely on a service, like us-east-1, then they are directly impacted by outages. There is safety in a herd and in numbers because everybody sits there, down and out. But, you don’t engineer your application to be a little more less than a single point of failure. It’s a bad idea to use a sole backing service for something, and it’s unacceptable from a business perspective.
Today, we’re talking to Chris Short from the Cloud and DevOps space. Recently, he was recognized for his DevOps’ish newsletter and won the Opensource.com People’s Choice Award for his DevOps writing. He’s been blogging for years and writing about things that he does every day, such as tutorials, codes, and methods. Now, Chris, along with Jason Hibbets, run the DevOps team for Opensource.com
Some of the highlights of the show include:
- Chris’ writing makes difficult topics understandable. He is frank and provides broad information. However, he admits when he is not sure about something.
- SJ Technologies aims to help companies embrace a DevOps philosophy, while adapting their operations to a Cloud-native world. Companies want to take advantage of philosophies and tooling around being Cloud native.
- Many companies consider a Cloud migration because they’ve got data centers across the globe. It’s active-passive backup with two data centers that are treated differently and cannot switch to easily.
- Some companies do a Cloud migration to refactor and save money. A Cloud migration can result in you having to shove your SAN into the USC1. It can become a hybrid workflow.
- Lift and shift is often considered the first legitimate step toward moving to the Cloud. However, know as much as you can about your applications and RAM and CPU allowances. Look at density when you’re lifting and shifting.
- Know how your applications work and work together. Simplify a migration by knowing what size and instances to use and what monitoring to have in place.
- Some do not support being on the Cloud due to a lack of understanding of business practices and how they are applied. But, most are no longer skeptical about moving to the Cloud. Now, instead of ‘why cloud,’ it becomes ‘why not.’
- Don’t jump without looking. Planning phases are important, but there will be unknowns that you will have to face.
- Downtime does cost money. Customers will go to other sites. They can find what they want and need somewhere else. There’s no longer a sole source of anything.
- The DevOps journey is never finished, and you’re never done migrating. Embrace changes yourself to help organizations change.

Quotes by Chris:
“Let’s not say that they’re going whole hog Cloud Native or whole hog cloud for that matter but they wanna utilize some things.”
“They can never switch from one to the other very easily, but they want to be able to do that in the Cloud and you end up biting off a lot more than you can chew…”
“Create them in AWS. Go. They gladly slurp in all your VM where instances you can create a mapping of this sized thing to that sized thing and off you go. But it’s a good strategy to just get there.”
“We have to get better as technologists in making changes and helping people embrace change.”
