At DNX we are committed to democratizing cloud technologies. Part of our plan is to develop and release to the public a large part of what we use with our clients.
After a little more than 1 year, this strategy translated into:
And here’s our update of that happened in the last few months.
DNX One — Updates
One is how we call our platform deployed on top of AWS. It’s a set of terraform stacks and modules to set up our client’s AWS accounts following well-architected concepts and with efficiency and cost in mind.
For this update, we focused on the themes below.
Added new alarms to the stack:
[terraform-aws-ecs-app]The alarm on the number for healthy tasks less than 2
[terraform-aws-ecs]The alarm on EFS credits running low
[terraform-aws-ecs-app-front]Renaming alarm for 500 errors to be more descriptive of the actual metric
With these above features, we are improving the AWS Operational experience across customers, by adding crucial monitoring alarms to avoid services disruption.
We improved our ECS modules to support blue-green with a manual cutover. This means the application can be deployed to production and be accessible on a different URL for validation, without affecting the live application. And then, the decision between cutting over or discarding can be made. That improves the continuous delivery model that we apply across DNX clients, allowing zero downtime and a better way to test new features without affecting real users.
[terraform-aws-ecs-app]Removing the blue domain as access to blue will be done using the test listener in the ALB; Changes to allow blue-green with manual cutover
[terraform-aws-ecs]Blue-green using test listener; Allow real blue-green with manual cutover
We implemented in our stack, for non-production environments, an option to power off instances at night. This technique is also covered in a blog post.
[terraform-aws-ecs]Scheduler to scale ASG to zero outside business hours
There’s also a new module called
terraform-aws-billing that helps customers track their AWS bill with alarms and budgets, sending alerts directly to their Slack using AWS Chatbot.
To help with compliance, we released a new terraform module that adds alarms on CloudTrail events:
The new security baseline module enables HIPAA customers to follow CIS Amazon Web Services Foundations.
Other important updates
[terraform-aws-ecs]Adding optional internal ALB for private APIs
As an effort to simplify deployments of infrastructure-as-code and applications, we started developing a CLI called
The goal is to provide a layer of PaaS on top of AWS and reduce the complexity of scripts inside the client’s code repositories.
