Comprinno conducted the Well-Architected Review (WAR) in 4-5 sessions and helped the BigYellowFish team in answering a few foundational questions which helped them learn how well their architecture is aligned with cloud best practices. Guidance and recommendations were provided for making improvements in the architecture.

As part of the remediations, Comprinno implemented AWS Organization structure consisting of separate AWS accounts for the various environment like development, staging, pre-production, production, logging, security & a management account. AWS Organization root was managed and all other AWS accounts were configured as child accounts. Multi Factor Authentication (MFA) was enabled for the root user on all AWS accounts as it is a simple best practice that adds an extra layer of protection on top of your user name and password. IAM password policy with least privilege was configured as per AWS CIS benchmark compliance. AWS SSO with users having restrictive access to AWS accounts, was created on the management account.

Logging and monitoring was enhanced by enabling VPC flow logs for production account and installing AWS CloudWatch log agent to log application logs in CloudWatch. AWS Cloudwatch agent was installed on EC2 instances to monitor memory & disk for EC2 instances or monitor the compute resources using the monitoring tool like data dog.

Amazon GuardDuty and AWS Config were enabled as per security best practices.

AWS WAF is configured for the application load balancer as an additional level of security against common web exploits and bots, that may affect availability, compromise security or consume excessive resources. Encryption was enabled for EBS volumes, Amazon S3, Amazon RDS and other AWS services which support encryption at rest.

Incident management was implemented using AWS System Manager Incident Manager which is designed to help users mitigate and recover from incidents affecting their AWS-hosted applications. Incident Manager increases incident resolution by notifying responders of impact, highlighting relevant troubleshooting data, and providing collaboration tools to get services back up and running. Alarms for critical servers were created with SNS integration for email alerts. AWS Backup service was used to backup critical resources hosted in EC2 instances, EBS volumes, RDS & S3.

AWS X-Ray was integrated with APM tool in the application to help developers analyze and debug production, distributed applications. Autoscaling for compute hosting applications was implemented which assured scalability during peak demand volumes guaranteeing a better customer experience.

AWS Cost and Usage Report was configured to track your AWS usage and provide estimated charges associated with AWS account. AWS budget was configured and a notification was set for breach of billing threshold.
