  • Security aspect
    o Custom VPC (Instead of default VPC)
    o Route tables and NACL configurations for provisioning Private vs public subnet, o Use VPC end points to use services like S3
    o IGW, NAT GW for Public network Access
    o Appropriate Security groups for each resource
    o IAM roles for different AWS resources
    o Data security in transit and at rest

    ▪ Data encryption using ACM key manager

    ▪ HTTS endpoints with AWS certification manager o Auditing and Compliance requirements

    ▪ Audit trails – Amazon CloudTrail

    ▪ Access Control: User Access management (IAM Users)

  • Data Availability & Data latency

    o Multi-zone Load balancing using ELB
    o CloudFront distribution for static content (CDN)
    o Database read replication- MongoDB
    o Use of High IO optimized high perform storage volumes (ELB) o Configuring non-critical reads from read replica
    o Frequently called reads through Elastic mem-cache

  • App Data Analytics
    o Cloud watch dashboard metrics (Memory/CPU utilization, Hit rate etc.) will help to

    ▪ Get actionable insights to optimize resource utilizations ▪ Get anomalous behavior in the system
    ▪ Take automated actions based on CloudWatch Alarms

  • Cost and performance tuning: Based on the data analytics insights on usage pattern, we can see that scaling requirement of some features will be much higher than others.

    o ECS are some available options to scale micro service containers based on need

  • Launching new Features: With a hybrid approach, by using AWS serverless architecture for mobile users.

    o AWS API GW and Lamda functions
