Work Experience
Infrastructure Technical Support Specialist
Accenture
- Created, tested, and verified a Tanium package for a VMware Tools version update. I tested the package on test and UAT environments and fixed vulnerability issues by implementing it in the development and production environments.
- Tracked the failed targeted servers using Tanium reporting tools, identified the error code, and fixed it during the following agreed schedule.
- Used PowerShell scripts to determine, using vCenter information, whether the server versions were updated or not.
- Completed the VMware Tools version updates for 15,000 Windows and RHEL servers within six months.
Infrastructure Management Services Operation Lead
AIG
- Introduced 24/5 support shifts for the patch and antivirus management team requiring global team assistance both during the day and night. This support team's availability helped reduce escalations.
- Joined high-severity and priority calls when required and performed change implementations during non-business hours.
- Reduced higher management escalation by providing support engineers at all hours.
- Obtained new projects due to the success of assigned tasks completed on time and with improved individual performance.
Project History
VMware Tools Version Updates
The step-by-step process included:
• Compiling the servers list installed with VMware Tools, creating a deployment list, and updating in SharePoint for access by the project team.
• Segregating the servers by UAT, development, non-production, and production environments.
• Identifying the server patching group that required a VMware Tools version update during the patching maintenance window, saving multiple maintenance windows and unnecessary downtime.
• Identifying the tools to update the version: namely, the Tanium package, Windows PowerShell scripting, and manual remediation.
• Creating a Tanium package and executing it on UAT and test servers to test whether the package and script were updating correctly or not.
• Sending an email notification to shareholders and other interested parties.
