AWS Cloud Engineers design, implement, and manage cloud infrastructure on Amazon Web Services (AWS), ensuring scalability, security, and reliability.

Proficiency varies, but service selection depends on factors like workload requirements, cost, and integration capabilities, tailored to specific use cases.

Secure data and resources with IAM, VPC, security groups, NACLs, encryption, AWS WAF, and monitoring using services like AWS CloudWatch.

HA ensures minimal downtime. Design architectures with multiple Availability Zones, load balancing, and failover mechanisms for resilient and available applications.

The framework provides guidance on building secure, high-performing, resilient, and efficient infrastructures through best practices, including the five pillars of the framework.

Use tools like AWS CloudFormation or Terraform to define and automate the provisioning and management of AWS resources in a structured, version-controlled manner.

Monitor resource utilization, implement cost allocation tags, use AWS Cost Explorer, and leverage reserved instances to optimize costs while maintaining performance and scalability.

ECS simplifies container orchestration by allowing you to deploy, manage, and scale containerized applications on AWS infrastructure with ease.

Utilize services like Amazon S3 for data archiving, AWS Backup for backups, and AWS services to establish disaster recovery plans and replicate data across regions.

Implement Identity and Access Management (IAM), role-based access control, multi-factor authentication (MFA), and least privilege principles to manage secure access.

AWS certifications validate knowledge and skills. Mention the relevant certifications you hold, such as AWS Certified Solutions Architect, AWS Certified DevOps Engineer, etc.

Configure AWS CloudWatch Logs, CloudTrail, and security tools to monitor and log activities. Establish alerting and response procedures to address security incidents.

Consider migration strategies such as rehosting, replatforming, refactoring, or rearchitecting. Plan for data transfer, security, and application compatibility during migration.

 Utilize Auto Scaling, Application Load Balancers, and Elastic Load Balancers to automatically adjust resource capacity to meet varying workloads.

AWS Lambda allows running code without provisioning servers. Use it for serverless computing by defining functions and triggering them based on events.

Design VPCs with subnets, security groups, and network ACLs to isolate resources securely. Employ VPNs, Direct Connect, and peering to connect VPCs.

AWS and customers share responsibility for security. AWS secures the infrastructure, while customers are responsible for securing data, applications, and configurations.

Implement AWS services like AWS Config and AWS CloudTrail to monitor and audit compliance, and configure security controls based on specific regulations and standards.

Optimize application performance with auto-scaling, cache mechanisms, load balancing, and database performance tuning, while monitoring with AWS CloudWatch.

Choose AWS services like Amazon S3 for object storage, Amazon EBS for block storage, and Amazon RDS for managed databases, based on specific storage requirements.

Use AWS DataSync, S3 Cross-Region Replication, and AWS Global Accelerator to transfer resources between regions efficiently with minimal disruption.

Monitor cost allocation tags, use AWS Cost Explorer, implement cost-saving measures like spot instances, and optimize resource utilization to manage costs effectively.

 Implement rolling updates, canary deployments, and auto-scaling to minimize downtime during maintenance, ensuring continuous availability.

AWS CloudFormation is an IaC tool that enables the definition and automation of AWS resource provisioning, simplifying resource management and deployment.
