Towards a Cloud Native iRODS

Towards a Cloud Native iRODS

General Idea

  • iRODS is increasingly deployed in a cloud context
  • Automated deployment is currently complicated
  • Currently not a great fit for containerized environments
  • Client API implementations are entirely too complicated
  • State remains the enemy

Step 1: Create a new HTTP Proxy role for the iRODS server

  • Client RPC Invocation

    • connects to an iRODS Agent

    • agent re-packs C into xml protocol

    • possibly base64 encode

    • curl request to a configured http endpoint

  • This will allow for on premises clients to work with cloud deployments such as

    • icommands

    • nfsrods

    • davrods

  • The proxy agents will be responsible for managing persistent information such as L1 descriptors, etc. assuming http requests are atomic in nature

  • We will need to re-package operations like READS and WRITES into new cloud friendly API invocations

Step 2: Statically Link Everything

  • Build and statically link iRODS and all its dependencies for use by the new API

Markus!

Step 3: The fun part

  • The catalog will be hosted as a separate service, e.g. RDS
  • The new executable assumes it is the Catalog Service Provider
  • All resources assumed to operate in 'detached_mode': S3 and UFS

Assumptions

Step 4: Towards the glorious future

  • The experimental iRODS API is all driven by JSON, which lends itself well to lambda-like deployment

  • The iRODS CLI and newer clients can migrate gradually to the new API

  • The addition of  read-some/write-some style API  interface without the need for persistence will allow new clients to work directly with an http style API
