What is iRODS

Distributed - runs on a laptop, a cluster, on premises or geographically distributed

Open Source - BSD-3 Licensed, install it today and try before you buy

Metadata Driven & Data Centric - Insulate both your users and your data from your infrastructure

iRODS as the Integration Layer

iRODS Core Competencies

The underlying technology categorized into four areas

Data Virtualization

Combine various distributed storage technologies into a Unified Namespace

  • Existing file systems
  • Cloud storage
  • On premises object storage
  • Archival storage systems

iRODS provides a logical view into the complex physical representation of your data, distributed geographically, and at scale.

Projection of the Physical into the Logical

Logical Path

Physical Path(s)

Data Discovery

Attach metadata to any first class entity within the iRODS Zone

  • Data Objects
  • Collections
  • Users
  • Storage Resources
  • The Namespace

iRODS provides automated and user-provided metadata which makes your data and infrastructure more discoverable, operational and valuable.

Metadata Everywhere

Workflow Automation

Integrated scripting language which is triggered by any operation within the framework

  • Authentication
  • Storage Access
  • Database Interaction
  • Network Activity
  • Extensible RPC API 

The iRODS rule engine provides the ability to capture real world policy as computer actionable rules which may allow, deny, or add context to operations within the system.

Dynamic Policy Enforcement

  • restrict access
  • log for audit and reporting
  • provide additional context
  • send a notification

The iRODS rule may:

Dynamic Policy Enforcement

A single API call expands to many plugin operations all of which may invoke policy enforcement

  • Authentication
  • Database
  • Storage
  • Network
  • Rule Engine
  • Microservice
  • RPC API

Plugin Interfaces:

Secure Collaboration

iRODS allows for collaboration across administrative boundaries after deployment

  • No need for common infrastructure
  • No need for shared funding
  • Affords temporary collaborations

iRODS provides the ability to federate namespaces across organizations without pre-coordinated funding or effort.

iRODS as a Service Interface

Federation - Shared Data and Services

Ingest to Institutional repository

As data matures and reaches a broader community, data management policy must also evolve to meet these additional requirements.

What is a Policy

A Definition of Policy

 

 

A set of ideas or a plan of what to do in particular situations that has been agreed to officially by a group of people...

 

 

So how does iRODS do this?

iRODS Policies

The reflection of real world data management decisions in computer actionable code.

 

(a plan of what to do in particular situations)

Possible Policies - The What

  • Data Movement
  • Data Verification
  • Data Retention
  • Data Replication
  • Data Placement
  • Checksum Validation
  • Metadata Extraction
  • Metadata Application
  • Metadata Conformance
  • Replica Verification
  • Vault to Catalog Verification
  • Catalog to Vault Verification
  • ...

Policy Composition

Consider policy as building blocks towards capabilities

Follow proven software engineering principles:

    Favor composition over monolithic implementations

Rules and Dynamic Policy Enforcement Points can be overloaded and fall through

Implement or configure several rule bases or rule engine plugins to achieve complex use cases

When - The Event Handler

Policy Composition

Consider Storage Tiering:

  • Violating Object Identification
  • Data Movement
    • Data Replication
    • Data Verification
  • Data Retention
  • Packaged and supported solutions
  • Require configuration not code
  • Derived from the majority of use cases observed in the user community

Use Cases

iRODS

The Wellcome Sanger Institute

Sanger - Replication

  • Data preferentially placed on resource servers in the green data center (fallback to red)
  • Data replicated to the other room.
  • Checksums applied
  • Green and red centers both used for read access.
