Managed services spanning mainframe operations and multi-cloud modernization
Ensono runs managed infrastructure across two worlds at once: a mainframe core (z/OS, CICS, DB2, RACF, COBOL) and multi-cloud estates on AWS, Azure and GCP built with Terraform, Bicep and CloudFormation. It is adopting ServiceNow ITOM, Grafana and OpenTelemetry while replacing Netcool, SolarWinds and Broadcom, which points to a consolidation of legacy monitoring onto open observability. Accelerating, senior-heavy engineering hiring backs that shift.
