I’ve been working as lead SRE and architect on an IL5 compliant UCaaS platform for almost 3 years, and I have never meet anyone else that was doing the same. My call center platform deploys 35 applications spread across 120 servers for each new customer. When you include a staging environment and tools, I’m going to bat for certification with 300 RHEL and 120 Windows servers in IL5 hosted Data Centers……it’s a pig, and we are leveraging deployment automation that reduced our 6 month manual build and hardening time frame down to 6 days.
