How can enterprises leverage cloud to deliver the most value to their customers? In this webinar, the travel and lifestyle reward company, InterMiles, discusses its continuous modernization approach using AWS services. By leveraging its AWS expertise, Infostretch helped InterMiles cut costs, improve performance and optimize operations. With a robust application in place, users were able to leverage their core and trending loyalty features such as hyper-personalization, gamification and micro-redemption. InterMiles, AWS and Infostretch covered the strategic, technical and practical aspects of managing a successful app modernization in AWS cloud, including: • Modernization in Cloud: Kickstarting your modernization journey, the importance of continuous modernization and how to adopt a microservices model with reusable components between the native mobile and web platform.  • Cost Optimization and Operational Efficiency: The cost and operational benefits of optimizing your operations and infrastructure by consolidating web and mobile platforms on AWS. • AWS Well-Architected Review (WAR): Building a resilient cloud architecture and infrastructure using AWS Well-Architected Review (WAR) and identifying and addressing critical challenges with custom solutions.

24. AWS WAFR: FINDINGS & MITIGATION
Opportunity for better plan for
Disaster Recovery, impact of not
having DR strategy will be loss of data,
loss of reliability, trust and reputation of
brand, and loss of revenue during the
downtime
Mitigation Time: 4 weeks
• Implementation of backup and
restore strategy as per RTO and
RPO agreed with business
• CloudFormation templates for
infrastructure components
• Regular DR drills using backup and
restore strategy

AWS WELL-ARCHITECTED FRAMEWORK REVIEW
RELIABILITY
Opportunity for optimize instance
pricing selection model, incurs
higher cost of production and testing
workloads and increases overall
application and development cost
Mitigation Time: 3 weeks
• Reserved instances for production
workloads
• Multiple Savings Plans as per
business requirements
• Rightsizing of resources as per
AWS Cost Explorer
• Stop Test environment during
non-business hours
COST OPTIMIZATION
Potential for infrastructure
configuration solution reduces
the traceability to infrastructure
changes and no control on the
infrastructure deployments
Mitigation Time: 4 weeks
• IaC using CloudFormation
templates
• Bit Bucket for version control of
infrastructure changes
• GitOps for approval and
deployment of infrastructure
changes
• AWS Config for tracking
Infrastructure changes
