AWS Cloud Engineer (L2) - Infosys - Chennai

Cloud Infrastructure & AWS Application Operations for Verizon's enterprise cloud environment.

• Provisioned and managed AWS EC2 instances on Windows and Linux platforms — AMI selection, instance sizing, security group configuration, key pair management, and full lifecycle operations for Verizon's enterprise cloud environment.
• Engineered Auto Scaling Groups with custom Launch Templates, dynamic and scheduled scaling policies, and ELB integration — enabling applications to automatically adjust capacity based on real-time demand and sustain high availability during traffic peaks.
• Deployed and configured end-to-end websites on AWS — set up EC2 web servers (IIS/Apache), hosted static sites on S3, mapped custom domains via Route 53, and enforced HTTPS through SSL certificates — delivering fully functional, live websites on cloud infrastructure.
• Architected CloudFront CDN distributions — configured origins, cache behaviours, TTL rules, HTTPS at the edge, and geo-based routing to serve content with low latency across multiple global regions for Verizon's distributed user base.
• Designed and managed AWS VPC architecture — subnets (public/private), route tables, internet gateways, NAT gateways, security groups, and NACLs — ensuring secure and well-segmented cloud networking.
• Administered S3 buckets for data storage, backup, log archival, and static website hosting; configured lifecycle rules, versioning, and bucket policies for data durability.
• Managed EBS volumes and EFS file systems — provisioning, attaching, resizing, and snapshotting storage to meet application performance and availability SLAs.
• Configured Route 53 hosted zones with A, CNAME, Alias, latency-based, and failover routing policies for reliable DNS resolution across Verizon's cloud-hosted domains.
• Built AWS CloudWatch dashboards, custom metrics, log groups, and alarms for proactive infrastructure monitoring; integrated CloudWatch with Grafana for unified, real-time observability.
• Managed SSL/TLS certificate lifecycle — CSR generation, CA submission, installation, and renewal — eliminating certificate expiry incidents across all hosted applications.
• Managed Change Approvals (CA) for cloud deployments and contributed to data centre-to-AWS migration projects with minimal downtime.
• Applied IAM best practices — roles, policies, and instance profiles with least-privilege access — to strengthen the security posture of cloud environments.
