• Worked with AWS Cloud Formation Templates, terraform along with Ansible to render templates and Murano with Heat Orchestration templates in OpenStack Environment. • Analyzed various distributed file systems suitable for a cloud storage using a storage benchmark. Tested a private storage cloud using OpenStack SWIFT software and worked as well with OpenStack Multi-node installation, Configuration and Administration. • Working on CI/CD pipeline to deploy code to ROC agent using Bit bucket. • Written Chef Cookbooks, recipes using Ruby to automate the installation of Middleware Infrastructure like Apache Tomcat, JDK, and configuration tasks for new environments. • Created, expanded, and configured automation in Maven to automatically build, package, and deploy Java applications to multiple development and testing environments • Built and Deployed Java/J2EE to a web application server in an Agile continuous integration environment and automated the whole process • Followed Spring MVC pattern and used View Resolver to map web pages. • Setup, Configuration, Monitoring and Support of PostgreSQL Powa and pact tools. • Wrote Ansible Playbooks with Python SSH as the Wrapper to Manage Configurations of AWS Nodes and Test Playbooks on AWS instances using Python. Run Ansible Scripts to provision Development servers.

Worked with AWS CodePipeline and creating CloudFormation JSON templates to create custom VPC. Migrated a production infrastructure into AWS utilizing CodeDeploy, CodeCommit, OpsWorks. Knowledge of Amazon ECS Clusters and able to manage containers in it.  Configure and Manage EC2, Elastic Beanstalk, RDS, S3 Buckets, VPC, Security Groups, ELB, Auto scaling, ElasticCache, Glacier, SNS, SQS, SES, CloudWatch, ECS, CloudTrial, CloudFormation.  Utilized AWS CLI to automate backups of ephemeral data-stores to S3 buckets, EBS and create nightly AMIs for mission-critical production servers as backups. Deployed Elasticsearch with 10 nodes cluster in AWS environment for client applications.  Created Python scripts to automate AWS Services which includes ELB, Cloud front, Lambda, database security and application configuration also Developed them to take backup of EBS volumes using AWS Lambda, CloudWatch.  Utilized Ansible and AWS lambda, elastic cache and Cloudwatch logs to automate the creation of log aggregation pipeline with ElasticSearch, Logstash, Kibana stack (ELK stack) to send all our team's logs coming into cloudwatch, to process them and send them off to ElasticSearch.  Written Templates for AWS infrastructure as a code using Terraform to build staging and production environments. Defined Terraform modules such as Compute, Network, Operations, and Users to reuse in different environments.  Experience with Terraform to build infrastructure as a code.  Lightweight virtualization with Linux Containers and Docker.Used Terraform as “Infrastructure as a code” and modifying terraform scripts as and when configuration changes required.  Worked with AWS Cloud Formation Templates, terraform along with Ansible to render templates and Murano with Heat Orchestration templates in OpenStack Environment.

Setup Azure Virtual Appliances (VMs) to meet security requirements as software-based appliance functions. Implemented high availability with Azure Classic and Azure Resource Manager (ARM) deployment models, Worked on Continuous Integration (CI), Continuous Delivery (CD) pipeline for Azure Cloud Services using CHEF. Managing Azure infrastructure and automation with CLI and API and worked on Inbound and Outbound services with automation CHEF and deployed multiple resources simultaneously, using CloudFormation templates in Azure. Create and maintain fully automated CI/CD pipelines for code deployment using Octopus Deploy and PowerShell. Key Involvement in planning, developing and assisting the migration of client's on-premise infrastructure to Microsoft Cloud (Azure). Design and implement hybrid on premise and cloud migration and management strategy for the new hybrid cloud solution in single and multiple site data centers. Deployed Azure IaaS (VM’s) and PaaS role instances (Cloud services) into secure VNets with Azure Internal Load Balancers, subnets and created several SQL scripts as part of bug fixes. Manage deployment pipeline using TeamCity, VSTS and Octopus Deploy tools Worked on Operations Management Suite (OMS) to validate Windows updates, Azure Solutions, Service Health, Application Insights and availability sets, fault and update domains.

 Created AWS cloud formation templates to create custom-sized VPC, subnets, EC2 instances, ELB, security groups. Worked on tagging standard for proper identification and ownership of EC2 instances and other AWS Services like Cloud Front, cloud watch, RDS, S3, Route53, SNS, SQS, Cloud Trail.  Worked on Architecting and securing the Infrastructure on AWS using IAM, KMS, EMR, Cognito, API Gateway, Cloud Trail, Cloud Watch, Amazon Simple Queue Service (Amazon SQS), Config, AWS Kinesis, Lambda, NACL, Elastic Beanstalk, Redshift and CloudFormation.  Worked on tagging standard for proper identification and ownership of EC2 instances and other AWS Services like Cloud Front, cloud watch, RDS, S3, VPC, EC2, ELB, Route53, SNS, SQS, Cloud Trail.  Designed and architected cloud application deployment in OpenStack with Nova, Neutron, Keystone command line clients. Worked with OpenStack services such as Nova, Glance, Swift, Keystone, Heat, and Ceilometer.  Responsible to Architect, build and maintain Highly Available secure multi-zone AWS cloud infrastructure utilizing Chef with AWS CloudFormation and Jenkins for continuous integration.  Successfully migrated the technology stack from a data center with failing hardware and frequent service interruptions to a secure and highly available hybrid cloud infrastructure on AWS Web Services.  Wrote Lambda functions in python for AWS Lambda and invoked python scripts for data transformations and analytics on large data sets in EMR clusters and AWS Kinesis data streams.  Configured Kubernetes Replication controllers to allow multiple pods such as Jenkins master server in multiple minions. Managed Kubernetes charts using Helm, managed Kubernetes manifest files and created reproducible builds of the Kubernetes application.  Created Monsoon instance status page to search the instance and platform information. Migrated Monsoon metadata web app to Docker container.
