Exordos Core Overview#

Exordos Core is an open-source NoOps platform for automating the deployment, management, and operation of IT infrastructure and enterprise software. The platform can be used in local, private, public, and hybrid environments.

Exordos Core moves infrastructure management beyond the classic DevOps approach. Instead of disconnected tools that require constant manual coordination, it unifies infrastructure, access policies, and service lifecycle in one control plane. This reduces operational overhead, prevents configuration drift, and lets teams work at the level of intent rather than individual low-level operations.

Core principles#

Declarative management#

A manifest describes resources, their parameters, dependencies, configuration, and lifecycle rules. The platform determines the operations required to reach the declared state.

Reconciliation loop#

Exordos Core continuously compares the actual state of managed resources with the state declared in the manifest. When it detects a difference, the platform performs the actions necessary to restore the desired state.

Image-based provisioning#

Compute nodes are created and updated from images. During an update, the Node root disk is replaced with the target image while attached volumes and network identities are preserved. This approach makes environments reproducible and reduces configuration drift between nodes.

Elements#

Software is delivered as elements. An element contains a manifest describing dependencies, infrastructure resources, configuration, secrets, and installation, update, and removal rules.

Main components#

Compute — creates and manages virtual machines and physical servers.
Storage — creates and attaches disk volumes.
Network — manages network resources.
DNS — manages DNS resources.
Load Balancer — manages load balancers.
IAM — manages users, roles, and access permissions.
Secrets — stores passwords, SSH and RSA keys, certificates, and other confidential data.
Configs — stores and delivers configuration data to software components.
Services — manages system services on compute nodes.
Values Store — manages values, variables, and profiles used to parameterize manifests.
Element Manager — installs, updates, and manages the lifecycle of elements.
Marketplace — provides public and private element catalogs.

Core platform resources#

The platform provides additional resource types; the following are its core resources.

Resource	Purpose
Node	A virtual machine or physical server. A Node is not a container.
Set	A group of homogeneous Nodes with a specified replica count and update strategy.
Volume	An attachable disk volume for persistent data.
Network	A network resource connecting compute nodes and services.
Config	Configuration data delivered to components.
Secret	Confidential data such as passwords, keys, and certificates.
Service	A system service that runs on a Node.
Element	A package of application or infrastructure software.
