Summary
🤩
Rockstar🎓
Top SchoolJosh Salomon is a seasoned software architect and distributed storage expert with over three decades of engineering experience and seven years focused on open-source cloud storage at Red Hat. He co-designed Ceph’s read balancer and has driven architecture and cost-reduction efforts for large-scale cloud deployments, drawing on prior leadership of ScaleIO and deep BSS/domain modeling at Amdocs where he co-chaired the TMF SID team. Based in Israel, he blends rigorous information and data modeling with hands-on systems work—refactoring core Ceph components, adding pool-level read-ratio controls, and implementing unit-tested improvements to balancer logic. Comfortable at the intersection of telecom BSS, enterprise integration (billing, ordering, CRM) and storage systems, he’s equally adept at standards, training, and product security. An uncommon combination of protocol-level storage tuning and formal information modeling enables him to translate complex telecom and cloud requirements into resilient, performant architectures.
