OVHcloud Associate flashcards

32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Bare Metal Cloud

OVHcloud's dedicated server product line, provisioned automatically through the API or control panel with full hardware access and no hypervisor layer between the customer and the CPU.

Rescue mode

A temporary network-booted Linux environment used to repair a server's disks, reset the root password, or recover files without reinstalling the operating system.

Reverse DNS (PTR)

The record mapping an IP address back to a hostname; OVHcloud lets you set it per IPv4/IPv6, and an incorrect value often causes outbound email to be rejected.

VPS vCore guarantee

A VPS guarantees a fixed number of virtual CPU cores and RAM, but the physical host is shared with other customers, so sustained performance can vary.

SLA credit claim

Compensation requested when measured availability drops below the contractual threshold; it is filed through the support ticket system within the stated claim window.

Object Storage S3 compatibility

OVHcloud Object Storage exposes an S3-compatible API with buckets, access keys, and bucket policies, so standard S3 SDKs and tools work with minor endpoint changes.

Snapshot vs backup

A snapshot is an incremental point-in-time capture tied to the source volume; a backup is an independent full copy that survives deletion of the original.

NAS-HA

A high-availability NFS and CIFS file share service with paired nodes and tiered performance levels, used for shared storage across multiple servers or instances.

Object lifecycle rule

An automated policy that transitions objects to cheaper storage tiers or deletes them after a defined age, reducing cost without manual intervention.

Object lock

An immutability feature that prevents objects from being overwritten or deleted for a defined retention period, supporting compliance and ransomware-resistance requirements.

vRack

A private layer-2 network that connects OVHcloud services across data centres; each service must be attached to the vRack in the matching region.

Floating IP

A public IP address that can be detached from one instance and reassigned to another in the same region, enabling failover without changing DNS records.

Security Group

A stateful virtual firewall applied to instances or ports in Public Cloud; rules define allowed ingress and egress, and the default policy must be verified.

Anti-DDoS (VAC)

OVHcloud's always-on DDoS mitigation that scrubs malicious traffic before it reaches the customer's public IP, with alerts and per-IP configuration in the panel.

Load Balancer health check

A periodic probe of backend instances; unhealthy instances are removed from rotation, and the check type and interval determine failover speed.

Firewall Network

An edge firewall for Bare Metal servers that filters traffic before it reaches the host, separate from host-based rules such as iptables or firewalld.

Public Cloud project

The billing and resource boundary in Public Cloud; quotas, budgets, IAM policies, and most resources are scoped to a single project.

Instance flavour

A named combination of vCPU, RAM, and disk size within a family such as general purpose, compute-optimised, memory-optimised, or GPU; resizing requires a stop and start.

Managed Kubernetes

A Public Cloud service where OVHcloud runs the Kubernetes control plane and the customer manages worker nodes and workloads, billed per node and per cluster.

cloud-init user-data

A bootstrap mechanism that passes configuration to a new instance at first boot, allowing automated user creation, package installation, and service configuration.

Public Cloud quota

A per-project limit on resources such as vCPU, RAM, volumes, and floating IPs; increases must be requested through support before scaling beyond it.

Hosted Private Cloud

A single-tenant VMware environment where OVHcloud manages the physical hosts and the customer manages vCenter, NSX, and virtual machines.

vSAN storage policy

A rule set defining failure tolerance and RAID level for virtual machine storage on a vSAN cluster, controlling resilience and usable capacity.

NSX edge gateway

The virtual appliance in a VMware private cloud that provides routing, NAT, firewall, and VPN services between logical networks and the outside world.

Veeam Managed Backup

An OVHcloud backup option for Hosted Private Cloud that uses Veeam to capture virtual machines on a schedule with configurable retention.

HPC host pack

The minimum purchasable unit of VMware hosts in Hosted Private Cloud, typically two hosts, with additional hosts added as options on monthly billing.

IAM policy

A rule in OVHcloud Identity and Access Management that grants specific actions on specific resources to a user, group, or service account.

Application key (AK/SK)

A credential pair used to call the OVHcloud API; permissions and IP restrictions are set per key, and keys should be rotated regularly.

Multi-factor authentication

A second authentication factor such as a TOTP code or hardware security key; OVHcloud can enforce it per account or per user group.

Support level

The subscribed support tier, such as Standard, Business, or Enterprise, which determines response times, available channels, and escalation paths.

Audit log

A record of account and resource events used for security review and troubleshooting; retention and export options depend on the specific OVHcloud service.

API console

An interactive web tool for exploring and calling OVHcloud API endpoints, useful for testing requests before scripting them with the CLI.
