Case type
Description
Solution
Application migration
A company plans to migrate its legacy application to AWS. The application is data-intensive and requires low-latency access for users across the globe. What AWS services and architecture would you recommend to ensure high availability and low latency?
EC2 for compute
S3 for storage
CloudFront for content delivery
Route 53 for DNS routing
Disaster recovery
Your organization wants to implement a disaster recovery plan for its critical AWS workloads with an RPO (Recovery Point Objective) of 5 minutes and an RTO (Recovery Time Objective) of 1 hour. Describe the AWS services you would use to meet these objectives.
Backup for regular backups of critical data and systems with a 5-minute recovery points objective (RPO)
CloudFormation to define and provision the disaster recovery infrastructure across multiple regions
Enable Cross Region Replication in S3 to replicate backups across regions
Setup CloudWatch alarms to monitor systems and automatically trigger failover if there are issues
DDos attacks protection
Consider a scenario where you need to design a scalable and secure web application infrastructure on AWS. The application should handle sudden spikes in traffic and protect against DDoS attacks. What AWS services and features would you use in your design?
CloudFront and Route 53 for content delivery
Auto Scaling group of EC2 across multiple availability zones for scalability
Shield for DDoS protection
CloudWatch for monitoring
Web Application Firewall (WAF) for filtering malicious requests
Real-time data analytics
An IoT startup wants to process and analyze real-time data from thousands of sensors across the globe. The solution needs to be highly scalable and cost-effective. Which AWS services would you use to build this platform, and how would you ensure it scales with demand?
Kinesis for real-time data ingestion
EC2 and EMR for distributed processing
Redshift for analytical queries
Auto Scaling to help scale up and scale down resources based on demand
Large-volume data analysis
A financial services company requires a data analytics solution on AWS to process and analyze large volumes of transaction data in real time. The solution must also comply with stringent security and compliance standards. How would you architect this solution using AWS, and what measures would you put in place to ensure security and compliance?
Kinesis and Kafka for real-time data ingestion
EMR for distributed data processing
Redshift for analytical queries
CloudTrail and Config to provide compliance monitoring and configuration management
Leverage multiple availability zones and IAM policies for access control.
