Infrastructure, Cloud & Platforms

01

Configuration, patching and protection

Maintain approved baselines, investigate drift and patch
exceptions, and verify that protection remains
operational. Plan updates around service dependencies
and maintenance windows, then check the result.

02

Compute, storage and service health

Track host contention, storage latency, cluster state and
application health together. Investigate the underlying
constraint behind the alert, then address capacity
pressure before it affects service.

03

Failover and recovery readiness

Check whether surviving hosts have capacity to absorb
a failure, replication is healthy, and recovery
dependencies are understood. A successful backup job
alone does not prove the service can be recovered.

Virtualisation & compute

Host health, clustering, resource allocation and hypervisor lifecycle.

Storage & data platforms

Latency, capacity, replication, multipathing and resilience.

Hyperconverged infrastructure

Node health, cluster capacity and coordinated platform updates.

Cloud & hybrid infrastructure

Workloads, configuration, connectivity, identity dependencies and consumption.

Microsoft 365

Tenant configuration, service health, email flow and identity dependencies.

Infrastructure monitoring

Host, cluster, storage and service health are monitored together. Capacity trends, resource contention and application dependencies give engineers the context to investigate alerts. DC9 engineers assess the issue, act on the cause and verify that service health has recovered.

Patch & vulnerability management

Vulnerabilities are assessed against the infrastructure in use, with exposure and business impact setting the priorities. Updates are planned around dependencies, maintenance windows and rollback requirements. DC9 verifies installation and service health after deployment, tracking failed updates and deferred remediation through to resolution.

Server hardening & configuration management

Servers and platforms are maintained against approved configuration baselines. Unnecessary services, excessive permissions and insecure settings are addressed without disrupting legitimate workloads. Controlled changes, drift investigations and documented exceptions keep the intended configuration clear.

Endpoint & server protection

Agent health, policy application, updates and reporting are monitored across the server estate. DC9 investigates missing or degraded protection and reviews exclusions so application requirements do not create gaps in coverage.

Application & data control

Application and script policies define what is trusted to run, with controlled exceptions for legitimate operational needs. Data safeguards reflect the workload and the information it handles. These controls protect services and data while allowing integrations and maintenance tasks to work.

Log monitoring

System, security and service logs support investigation of failures, unusual activity and recurring faults. Infrastructure health and recent changes provide context, helping DC9 engineers trace causes across dependent systems.

Run keeps it operating.

We manage platform health, capacity, patching and configuration
so services remain dependable.

Secure keeps protection effective.

We assess exposure, validate security controls and investigate threats across the same
environment.

01

Assess

Review health, exposure, capacity and support lifecycles.

02

Plan

Agree dependencies, maintenance windows and rollback.

03

Change

Implement approved changes with the right checks and communication.

04

Verify

Check service health and confirm the intended result.

05

Improve

Resolve recurring faults and update the operating baseline.
