Migrates to AWS for Scalable, Secure, and Compliant Digital Food Ordering

Komidaz Inc., the creator of KhaoDao—a digital dining platform—migrated to AWS with Graaho Technologies. The serverless, secure, and scalable solution enabled rapid deployments, improved performance, enhanced security, and reduced infrastructure costs. Partner: Graaho Technologies 
Customer: Komidaz Inc. USA (KhaoDao platform) 
AWS Competency Areas: Migration, Security 
Partner Role: End-to-end AWS migration, serverless architecture implementation, centralized security governance, CI/CD automation 
Key AWS Services: AWS Lambda, RDS, ElastiCache, Cognito, GuardDuty, Inspector, Security Hub, CloudTrail, CodePipeline 
Business Outcomes: Faster deployments, improved customer experience, enhanced security posture, cost optimization, operational efficiency KhaoDao, the flagship platform of Komidaz Inc., experienced rapid user growth that strained its legacy on-premise infrastructure. The team faced multiple operational hurdles: 

• Degrading performance during traffic surges 

• Manual server management and limited scalability 

• Fragmented and reactive security controls 

• Inadequate monitoring and delayed incident response 

• Difficulty expanding into new markets or regions 

Komidaz required a modern, cloud-native infrastructure to ensure seamless scalability, centralized security, cost efficiency, and operational agility. 

• Graaho Technologies, an AWS Select Tier Services Partner, designed and executed an end-to-end AWS migration and modernization strategy for Komidaz. The approach focused on: 

  Cloud Architecture Highlights: 

  • Serverless-first model using AWS Lambda for scalable backend logic 
  • Amazon RDS (PostgreSQL) for managed relational data 
  • Amazon ElastiCache for caching frequently accessed content 
  • Amazon API Gateway + Amazon Cognito for secured API management and user authentication 
  • Amazon SNS & Amazon SES for real-time notifications and email services 
  • Application Load Balancer & Auto Scaling to handle variable workloads 

  Security & Governance Enhancements: 

  • Amazon GuardDuty & Amazon Inspector for real-time threat detection and vulnerability scanning 
  • AWS Security Hub & AWS Config for centralized compliance management 
  • AWS CloudTrail for activity logging and auditability 
  • IAM + VPC Security Groups to enforce least-privilege and network segmentation 

  DevOps & Observability Stack: 

  • Fully automated CI/CD pipeline using AWS CodePipeline, CodeBuild, and CodeDeploy 
  • Centralized monitoring and alerting via Amazon CloudWatch 

Outcomes of Project & Success Metrics 

Key Area	Before Migration	After AWS Migration
Application Performance	Lagged during peak hours	Responsive and scalable with AWS Lambda
Deployment Time	1–2 hours with manual risks	~10 minutes with automated CI/CD pipeline
Server Management	Manual, error-prone	Fully automated with serverless architecture
Security & Compliance	Reactive and siloed	Centralized, continuous, GDPR and SOC 2 aligned
Monitoring	Minimal visibility	Real-time insights with CloudWatch
Infrastructure Costs	Fixed and growing	Optimized, pay-as-you-go model
Database Load	Bottlenecks during spikes	Offloaded with ElastiCache-based caching

 

• Graaho conducted a TCO comparison between the legacy environment and AWS cloud infrastructure. Key results: 
  • 40%+ reduction in total monthly infrastructure spending 
  • Zero CapEx due to elimination of physical server maintenance 
  • Increased developer efficiency with CI/CD automation reducing deployment overhead 
  • Right-sized architecture avoided overprovisioning while scaling on-demand 
  The cost savings combined with productivity gains yielded a strong ROI within the first few months post-migration.

• Serverless adoption greatly reduces infrastructure complexity but requires careful event-driven architecture planning 

• Security automation and centralized monitoring significantly improve risk management 

• Early investment in CI/CD pipelines ensures smoother deployments and supports continuous innovation 

• Caching strategy is crucial to improve responsiveness and reduce database load in high-traffic applications 

• Strong collaboration between internal teams and the AWS partner accelerates migration and ensures alignment with business goals
