FAQ Maintenance Cloud / Hybrid / On-Premise Infrastructure
What's the difference between cloud, hybrid and on-premise maintenance, and how can you unify management?
Cloud maintenance relies on hosted services from providers such as Azure, AWS or GCP, on-premise uses your in-house datacenters, and hybrid combines the two. Unification means centralized supervision, common operating procedures, homogeneous service levels and shared change management. This guarantees single visibility and identical responsiveness, whatever the environment.
How do you guarantee the availability of critical services on a day-to-day basis?
Availability is achieved through a combination of high-availability architectures, 24/7 monitoring, on-call operations and clear escalation procedures. Regular failover tests and continuity plans maintain service objectives, while post-incident reviews eliminate root causes and improve recovery times.
Does MCO include cybersecurity and regulatory compliance?
MCO includes patch management, configuration hardening, access monitoring and centralized logging. Activities are aligned with ISO 27001, RGPD and NIS2, with compliance tables, audit evidence and possible integration with a SOC/EDR/SIEM. Restoration and failover tests are part of the resilience and compliance approach.
What are the concrete financial benefits of proactive operation?
Proactive supervision reduces service interruptions and the costs associated with major incidents. Capacity optimization avoids over-provisioning, while automation frees up time and reduces manual intervention. Periodic reporting improves budget predictability and helps prioritize higher-value investments.
Is it possible to completely outsource operations, and how do you keep control?
Complete outsourcing is possible via facilities management covering supervision, maintenance, security and optimization. Control is maintained through steering committees, shared indicators, traceable access rights and up-to-date operating documentation. Upgrade decisions are arbitrated with the IT Department in line with business objectives.
How do you manage patches without impacting production?
Updates follow a planned cycle with qualification in a test environment, maintenance windows adapted to business constraints and post-patch checks. Sensitive applications benefit from documented rollback plans and reinforced post-intervention monitoring to secure recovery.
