Infrastructure Engineer (On-Prem / Hybrid)
Infrastructure Engineers who work with on-premises and hybrid environments provision physical servers and hypervisors, design SAN and NAS storage architectures, and manage data center operations that cloud-only DevOps engineers rarely touch. Their daily English covers writing change request documentation formal enough to satisfy an ITIL change advisory board, explaining a storage capacity shortfall to a vendor during a maintenance window, and documenting a migration wave plan that a bank auditor can follow line by line. This path builds the vocabulary for virtualization, bare metal, and data center infrastructure work.
Topics covered
- Virtualization vocabulary (VMware, Hyper-V)
- Bare metal & server hardware
- SAN/NAS storage architecture
- Data center operations language
- Physical network infrastructure
- On-prem to cloud migration
Vocabulary spotlight
4 terms every Infrastructure Engineer (On-Prem / Hybrid) should know in English:
A pre-approved, scheduled period during which infrastructure changes are permitted, typically requiring advance notice and a documented rollback plan
"The SAN firmware upgrade requires a two-hour change window during the Sunday 2 AM maintenance slot, with a documented rollback to the previous firmware."
VMware's live migration technology that moves a running virtual machine between physical hosts with no downtime, used for maintenance and load balancing
"We vMotioned all fourteen VMs off the host before patching, so the maintenance window caused zero service interruption."
A SAN access-control technique that restricts which hosts can see and access a specific Logical Unit Number, preventing accidental data corruption from unauthorised access
"A missing LUN masking rule let the new host see a volume it should never have touched, and it nearly reformatted production data."
A migration strategy that moves an application to a new environment (often on-prem to cloud) with minimal or no changes to its architecture, prioritising speed over optimisation
"We did a lift-and-shift of the legacy billing system to buy time, then scheduled a proper re-architecture for the following year."
