We at Source & Binary have led operations engineering and cloud infrastructure at companies such as Slack, Square, Confluent, and Segment. We've managed massive AWS installations, sat on AWS' Customer Advisory Board, and seen what works and what doesn't firsthand. Drawing on years of expertise building large-scale, mission-critical systems, we developed Substrate as an easy-to-use platform to automate the creation and management of multi-account AWS infrastructure, so that teams can get to work.

Casey Crites
Founding Engineer - Metronome
"All AWS access is immediately solved for us. It’s like having a team of SREs that have set a standard that makes it easy for non-SREs to follow."

Nate Brown
CTO - Defined Networking
"Having Substrate allowed us to bootstrap our AWS infrastructure in a way that large enterprises desire but struggle to accomplish."

Alaeddin Almubayed
CTO - Resourcely
"With security and privacy in mind, Substrate eliminates the need for managing long-lived keys, enforcing a policy of least privilege."
Creating an IAM role
Create new roles quickly. Ensure engineering can work efficiently and with least privileges.
Assuming a role with Substrate
It's easy to assume a role and work in another AWS account. Refer to your accounts using meaningful names instead of numbers.
Enumerate your AWS accounts
Easily see all your AWS accounts with human-friendly names. Generate a shell program to update accounts and apply Terraform modules.
Creating a new AWS account
New accounts can be created with a single command. Substrate generates Terraform for each account to bootstrap infrastructure as code.
How Substrate solves AWS access so you don't have to.
Isolation
Substrate allows you to separate your applications and environments by account, ensuring the highest level of isolation within AWS. Automated VPC creation and peering connects your applications inside an environment, while keeping environments such as development and staging isolated.
Roles
You can manage account access by creating roles for humans and applications with a single command. Day to day, engineers can use Substrate to assume roles to work with the AWS CLI, API, or access the AWS console.
Turnkey architecture
Substrate provides a proven account and network architecture without the engineering time. The isolation accomplished through multiple accounts enhances your application security and reliability. Compliance certifications like SOC2 become easier, and your engineering team can move faster without fear.
