- Deployment framework for the application deploys, I have used different Python modules including argparse, signal, traceback, yaml, logging, paramiko etc ., The framework involves the deployment of IAG applications from dev to Prod. The continous deployment tool used here is Atlassian bamboo. The framework is smart enough to read the deployment configuration(configurations are in yaml file) depending on the application and the environment that the different teams they what to deploy.The framework is integrated with different audit checks including bitbucket commit id/tag check for the application source repo, central framework repo, configuration repo, Artefact version check in Nexus Pro 3, Fetch the secrets from HashiCorp Vault, Upload the deploy and audit logs to Nexus3 and Splunk, Change request check from service-now for higher environments like PreProd, Prod, Check if the user deploying the application to prod have an access to fetch the secrets from Vault. The framework is used across 52 teams for their application deployment involving webSphere application deploys, file transfers…
- Deployment framework for database deploy, the audit checks are similar to the application deployment framework. I have used pandas and SQLAlchemy python libraries along with other libraries mentioned above for the deployment of databases from Dev to Prod environment. Pandas and SQLAlchemy are used for data manipulation. Databases including DB2, Oracle, PostgreSQL, MySQL.
