5. PROJECTS
I. Infrastructure Automation
Project Name Automated Environment Provisioning
Role Software Engineer
Technology Used Ruby, Shell scripting
Tool Used GIT, Jenkins, Vagrant, Puppet/Chef, Oracle VirtualBox
Team Size 3
Duration 3 Months
Client Internal TechM Project
Project Description:
Infrastructure automation is the process of creating multiple environments without any
manual intervention which includes installing an operating system, Installing and configuring
servers fora particular environments, Installing and configuring platform software’s for a particular
environments and patches update for particular software on the instance.
Traditionally Operations team following a manually interpetion of installing OS, platform
software’s, etc… So, Using DevOps we are automated the operations work.
Roles & Responsibility:
 Implemented Workflows Orchestration using Jenkins.
 Implemented Automate the Environment provisioning Using Puppet/Chef & Vagrant.
o Using VM Creation Engine such as Vagrant or Shell script, creating different
Environments (VMs). Configuration of platform software’s using Puppet/Chef.
o Creation of shell scripting & cookbook for system / software configurations
o For automation process, we have created the recipes in run list for the chef nodes to
configure the Application Server, Web Server etc...
o Shell script for configuration of IP, hostname and silent installation of chef client on the
different environments. Vagrant internally runs shell script to automate the
infrastructure.
o Implemented creating Chef Cookbooks and recipes and Puppet manifests (tomcat, web
logic, etc…) to automate the infrastructure platform configuration.
o Implemented Infrastructure as a code [Using GIT].
o Implemented automated patch update for the particular environment platform
software’s.

6. II. Release and Deployment Management
Project Name Release and Deployment Management
Role Software Engineer
Technology Used Shell Scripting, JSON, YAML
Tool Used AWS, Open Stack, Ansible
Team Size 3
Duration 3 Months
Client AERIS
Project Description:
In this project, we have covered the implementation of Infrastructure automation and
application deployment automation on Cloud using AWS, OpenStack and Ansible.
Also we havecovered the Cassandra DBAutomated installation, configurationand clustering
on Cloud using AWS JSON, OpenStack YAML templates respectively.
Traditionally following a manually process for creating the Stacks using AWS Deployment
scripts, so using DEVOPS we are automated the manual process.
Migration of AWS Deployment scripts into OpenStack HOT Templates.
Roles & Responsibility:
 Implemented automated instance creation with Cassandra DB and TOMCAT, which has created
in a single template using AWS JSON, OpenStack YAML.
 Also we have coveredthe Cassandra DB Automated installation, configuration and clustering on
Cloud using AWS JSON, OpenStack YAML templates respectively.
 Load balancing has been implemented on multiple TOMCAT Instances using AWS JSON,
OpenStack YAML templates respectively.
 Implemented automated configuration [between Cassandra DB and TOMCAT webpage], which
enables Cassandra DB changes on TOMCAT webpage dashboard.
 Implemented OpenStack YAML template for creating the instances for our client using
automation process.
 Implemented automation process of OpenStack Cloud computing using ANSIBLE
 Implemented the HOT Templates of AERCloud Deployment scripts for creating stacks on
OpenStack.

7. III.DevOps Practice:
Project Name DevOps Practice
Role Software Engineer
Technology Used Shell Scripting, JSON, YAML, Ruby
Tool Used SVN, Jenkins, CDA, SSH, Puppet, Ansible, Chef, GIT, Vagrant,
Rundeck, Teamforge, IBM UDeploy, Docker
Team Size 16
Project Description:
DevOps is the practiceof operations and development engineers participating together in
the entire service lifecycle,fromdesign through the development process to production support.
DevOps practicein order to improve collaboration and productivity by automating
infrastructure, automating workflowsandcontinuously measuring application performance
DevOps forthe End-to-EndSolution from Continuous planning to Continuous Monitoring
Release management for a company by standardizing development environments. Events
can be more easily tracked as well as resolving documented process controland granular reporting
issues. Companies with release/deployment automation problems usually have existing automation
but want to more flexibly manage and drive this automation - withoutneeding to enter everything
manually at the command-line. Ideally, this automation can be invokedby non-operations
resources in specific non-production environments. Developers are given more environment
control,giving infrastructure more application-centric understanding.
Training
 Trained on CollabNet Team Forge
 Trained on IBM UDeploy
Strength
 Excellent analytical, organizational, and planning skills.
 Efficient in leading and motivating the team towards achieving organizational goals.
 Proficiency in grasping new technical concepts quickly and utilizing the same in a productive
manner.
