Get licences for new tools, Implement DevSecOps, Rollout into production . Enhance CI/CD as per new requirements. e.g., Jenkins, GitLab, Maven, Junit, Jfrog, Sonarqube, Selenium, Ansible, Shell Scripts, Python Scripts.3. Service Lifecycle Management (SLM) in Hybrid Cloud Environment : Did POC with one developer . Provision the service ; upgrade the service, de-provision the service; using Jenkins (different pipelines for different IaaS for SLM), Terraform (create VMs with golden images), Packer (create golden image with required software packages), Ansible (configure the services), Spring Boot Java app(triggers the Jenkins Pipelines for SLM), PostgreSQL database in GCP and AWS . As part of this POC , implemented DevOps service life cycle management.4 Environment (full application stack deployed on different VMs) booking system: Guided a team of 3 members and implemented POC, environment booking system for effective utilisation of pre-deployed and ad-hoc environments in Angular 8, Spring Boot Java Web App, PostgreSQL database, Android mobile app in Agile way. With this app, project teams can block the environment for Dev, testing purposes, check the availability of environments in calendar view, verify the utilisation of environments.
