PROFESSIONAL EXPERIENCE

Cloud Engineer

Confidential

Responsibilities:

• Designed and Implemented AWS Organizations for Confidential cloud teams to centrally manage billing, control access, compliance, and security; and share resources across Confidential AWS accounts. Services used- Cloudtrail, S3, AWS Config, Service control policies, SNS, Lamda, Cloudwatch, apply password policies, RBAC, AWS SSO, IAM policies enforcement.
• Migrated AWS Cloud applications from Elastic Beanstalks (EBS) to Managed kubernetes service (AWS EKS)
• Jenkins Migration: Challenging for each engineering team to perform version upgrades, security patching, disaster recovery of their own Jenkins instances. Build a Jenkins service on managed kubernetes platform which is highly available and scalable. Created a migration plan by analyzing the old Jenkins instance, resource planning, sizing of the development efforts.
• Deploy Jenkins on Managed kubernetes and performed scaling configuration to meet the increased performance needs and did capacity planning for Infrastructure
• Created kubernetes clusters using helm, cluster-autoscaler, cert-manager, logging-operator, metric-server, signal-fx agent, spot-termination handler, kube2iam, external-dns, nginx-ingress, openEBS
• Migrated the legacy monitoring checks from Nagios to modern advanced SaaS based platform SignalFX, and routed them to PagerDuty to alert Operations for any critical alerts.
• Deployed Qualys security sensors on all Docker container images stored in ECR to improve the container security and prevent against the security vulnerabilities
• Implemented the log analytics solution by capturing the log for Kubernetes clusters and sent to Sumologic for real time monitoring.
• Enable New Relic APM for Customers using Confidential Cloud products.
• Evaluate the new product Buy v/s Build with a clear recommendation & plan to implement
• VPC peering for Kubernetes clusters for different AWS accounts
• Scrum master to handle the two different scrums in Nexus model, performed sprint planning, define approach, sizing and estimations, resource planning, identify dependencies and unblock team. Create sprint reports/velocity charts.
• Performed EKS cluster upgrade, Configure the cluster metrics for container, Pods, instances and configured the SignalFX monitoring dashboard to alert on any failures. Monitoring dashboards using Grafana.

• Improved AWS Cloud monitoring: Improved Reporting on Sites In/Out of Monitoring. Confidential only monitors a single Prod environment on each cluster. Sometimes customers are not added to monitoring, or monitored apps are de-provisioned. We created a report and sent to BI tool DOMO by using AWS S3 connector API by writing a Jenkins Job
• Maintain the server configuration using Terraform, Ansible. Setup RBAC in ISTIO
• Change management, Release management and send the release notes to stakeholders
• Supported Workflow Notificationsto receive feedback about workflow status changes and get alerted on failures. Workflows send notifications to SNS topics, each stage its own, to which the Worfklow Notifications service SQS queue is subscribed during the deploy process.service interacts with the queue and publishes human readable messages to the Slack, SignalFX, Pagerduty
• Confidential Hosting operations using workflows (eg. volume resize) send a notification via AWS Simple Notification Service. This microservice subscribes to SNS topics via an SQS queue (ie. converts push to pull notifications to retain state) and sends a message to Slack channel 'workflow-events' on workflow status changes. On workflow failures, it sends an alert to PagerDuty.
