• Worked with AWS EC2, S3, RDS, VPC, Route 53, IAM services, Cloud Watch, Load Balancer, Auto Scaling, CloudFormation, AWS Migration Hub, Snowball, AWS Single Sign - On, CloudFront, ECS, EKS.
• Used AWS ECS to schedule the placement of containers across the cluster based on resource needs, isolation policies, and availability requirements.
• Used AWS EKS to run the Kubernetes management infrastructure across multiple zones to eliminate a single point of failure and created alarms and trigger points in CloudWatch based on thresholds and monitored the server's performance, CPU Utilization, disk usage.
• Used Terraform to manage multiple servers and handled cross-cloud dependencies which simplify management and orchestration.
• Codified production environment using Terraform and then shared with staging, QA and Dev and used these configurations to rapidly spin up new environments to test in and then be easily disposed of.
• Worked on Ansible to provision AWS services and infrastructure automation in a SaaS environment and for dynamic scaling-up and scaling-down of machines.
• Created and used Ansible templates to create customized configuration files for hosts and used Ansible Vault in playbooks to protect sensitive data.
• Experience in implementing continuous delivery (CD) pipeline with Docker, Maven, Jenkins, GitHub, Nexus and AWS AMI's in Linux environment.
• Worked on setting up Upstream and Downstream Jobs with Jenkins and used scripts to Jenk ins Pipeline jobs and set up the End User Security.
• Built additional Docker Slave nodes for Jenkins using custom built Docker images and instances.
• Experience in managing software artifacts required for development using repository managers like Nexus Artifactory.
• Experience in Administration/Maintenance of source control management systems, such as SVN, GIT (Distributed Version Control)
• Set up CRON jobs for automated processes and extremely familiar with usage of SSH and ftp / sftp /scp / telnet for remote connections.
• Monitored the servers & applications using Nagios, Cloud Watch.
