The Ordinary Experts Zulip Pattern is a custom AMI + open-source AWS CloudFormation template that provisions a production-ready, AWS infrastructure solution for deploying Zulip 9.4.
Overview
The Ordinary Experts Zulip Pattern is an open-source AWS CloudFormation template that offers an easy-to-install AWS infrastructure solution for quickly deploying Zulip, using both AWS and Zulip best practices. Automatically configured to support auto-scaling through AWS Autoscaling Groups, this solution leverages an S3 bucket for user generated content between application servers. It also provisions an ElastiCache Redis cluster for cache. It configures SES with Easy DKIM for emails, and configures Route53 with convenient DNS entries. The template ensure multi-level security by incorporating AWS IAM for federated access to resources with least privilege and AWS managed keys and Secret Manager to manage secrets for encryption of data at rest and in transit. We support multiple availability zones using an RDS Aurora Postgresql cluster and EC2 Auto Scaling Groups.

CloudFormation Template (CFT)
AWS CloudFormation templates are JSON or YAML-formatted text files that simplify provisioning and management on AWS. The templates describe the service or application architecture you want to deploy, and AWS CloudFormation uses those templates to provision and configure the required services (such as Amazon EC2 instances or Amazon RDS DB instances). The deployed application and associated resources are called a "stack."
