Introducing load-balanced-https apps

Boxfuse originally launched with two types of apps: single-instance for applications using Elastic IP addresses and load-balanced for applications using Classic Elastic Load Balancers. Over time we have added support for additional types of applications such as workers apps and one-off apps to support more diverse types of workloads.

Today Boxfuse is expanding further with support for load-balanced-https apps using AWS Application Load Balancers, together with Auto Scaling Groups and optionally custom domains and TLS (SSL) certificates.

load-balanced-https

How does it work?

When you create a new load-balanced-https app using either the Boxfuse Console

create

or the Boxfuse Client

> boxfuse create my-app -app.type=load-balanced-https

Boxfuse will be set up to automatically provision and configure all necessary resources when the app is deployed.

Just for the ALB this includes:

  • a new ALB (Application Load Balancer)
  • a security group with the correct permissions for the ALB
  • one or more listeners for the correct ports on the ALB
  • a target group associated with the ALB
  • rules connecting the listeners to the target group

Why Application Load Balancers?

AWS Application Load Balancers come with a number of important improvements for applications serving traffic over HTTP(S) including HTTP/2 and WebSockets, while building on the important features you already love like Auto Scaling and automatic TLS certificate management.

Seeing it in action

So let’s see how this works if we deploy our sample Spring Boot application on AWS:

> boxfuse run -app.type=load-balanced-https -env=test -tls.type=acm -domain=hello.boxfuse-example.com

Creating hello ...
Successfully created app hello (type: load-balanced-https, tls: acm, db: none, logs: cloudwatch-logs)

Waiting for ALB Target Group to put instances in service ...
ALB: i-063c0eab44eb5d87c [healthy]
Successfully running myuser/hello:1.0 in test at https://hello.boxfuse-example.com/

And our app is fully up and running, load balanced in an auto scaling group with a custom domain and an automatic TLS certificate.

All deploys from here on are performed with zero downtime by simply launching a new auto scaling group and switch out the old one within the target group.

BYOTG (Bring Your Own Target Group)

Advanced users also have the option to configure their own ALB and Target Group. From there all that is needed is simply pointing Boxfuse at the name of the desired Target Group and Boxfuse will use that one instead of the ALB and Target Group auto provisioning described above.
