In Zscaler, my team is currently responsible for the deployment of ZIA services across thousands of bare metal servers. Over the years, we have significantly optimized our processes and taken on a broad range of responsibilities, including:
1.Streamlined Server Provisioning: Three to four years ago, it took us around three weeks to manually provision these servers at customer on-premises sites. Through automation, we've reduced that time to just 7-8 hours.
2.Automated Monitoring and Triage: We’ve developed a continuous monitoring system and designed a Python framework that automates the triage of Zscaler services and identifies faulty servers.
3.Self-Service Capabilities: We’ve introduced self-service options for system triage and server provisioning, integrating robust RBAC processes to ensure security and access control.
4.Scripting for Automation: We create Ansible playbooks, shell scripts, and Python scripts to automate various tasks, ensuring efficiency across individual processes.
5.End-to-End Automation: Our team has fully automated the provisioning process, from server deployment to generating automated reports.
6.Capacity Planning Automation: We’ve automated capacity planning and provide regular reports to customers, keeping them informed of their server and service capacity.
7.AI Integration for SRE Challenges: We're now applying AI to real-world SRE challenges such as monitoring, alerting, and incident management to further enhance system reliability and responsiveness.
