What is MOINC?

Mora Open Infrastructure for Network Computing

“It is a working prototype for an architecture

combining the paradigm of Web Services with

Grid Computing and Volunteer Computing”

“Hmm… Flashy name! So, what is MOINC?”

Web Services Today…

Poor scalability

Poor availability.

Degradation of performance

when subjected to heavy loads.

“The current Web Services

paradigm has a number of critical

limitations”

Clustering

Current Trends…(cont)

“The traditional

way of providing high

availability and

performance”

Current Trends…(cont)

Grid Computing

• Coordinates resources

that are not subject

to centralized control.

• Uses standard, open,

general-purpose protocols and

interfaces.

• Delivers non-trivial qualities of

service

“A special type of distributed

computing”

Current Trends…(cont)

Volunteer Computing

“Technically similar to

Grid Computing. But…”

• Can be implemented using

inexpensive commodity

hardware.

• Open to large communities.

• Users should trust

applications and vice versa.

How MOINC Fits In…

“MOINC is a fusion of the

best of Grid Computing and

Volunteer Computing with

Web Services”

“Sounds interesting…

Let’s hear more”

MOINC Quick Facts

“MOINC is a brainchild of Dr. Sanjiva Weerawarana”

Three primary components

MOINC Server

MOINC Server Manager

MOINC Client Agent

Components linked via the Thisara Communication Framework.

Research & development started in April 2008.

Aim – Improving the availability and scalability of Web Services through a

blend of Web Services and Grid/Volunteer Computing.

MOINC Server

The core component of the MOINC platform.

Manager and coordinator.

Grid membership manager.

Service and module management.

Configuration management.

Shared repository.

MOINC Server management console.

Default member.

Grid Membership Manager

Concept of Clustering Domains.

A clustering domain contains a set of services.

Each node is assigned to one or more domains.

When a node is assigned to a domain all the services in the

domain are deployed in the node.

Domain Manager

Low level membership management via Apache Tribes

Multicast based group communication framework.

High level membership management via Thisara

Grid Membership Manager

Idle Request Tracker (powered by Thisara)

MOINC Agent instances residing on remote machines notify the MOINC Server

when they are willing to join the grid by sending an Idle Request message.

Adding nodes dynamically to the grid

(powered by Apache Synapse)

Removing nodes dynamically from the grid (powered by Apache Synapse)

Node state maintenance

(powered by Apache Axis2 / Tribes)

Basic dynamic load balancer

Smart Load Balancer

Validation API and domain manager

Service & Module Management

Addition and removal of service artifacts.

Deploying and undeploying Axis2 modules.

Hot deployment.

Configuration Management

XML based global configuration model.

Easily extensible by defining custom properties and parameters.

Inspired by the Apache Axis2 configuration model.

Separate configuration for Management Console for loose coupling.

Server Management Console

JavascriptWeb

Services

W

S

F

XSLT

Web 2.0 like.

Inspired by the WSO2 WSAS UI framework.

Core functionalities implemented as Java Web Services.

Executes Web Services through WSO2 Web Services Framework

(WSF) for Javascript.

Displays grid status, service, module and

system information.

Default Member - WSAS

Clustering Layer Clustering Layer Clustering Layer

Tribes Tribes TribesManagement

Console

Uses WSO2 WSAS (Web Services Application Server)

Runs in conjunction with the shared repository.

Acts as the container for the Server Management Module.

Becomes a default member for each clustering domain.

Thisara Communication Framework

Protocol Designed from the scratch.

Message format inspired by the Financial Information Exchange (FIX) Protocol.

Simple, light-weight, text-based.

TLS secured.

Implemented on Apache MINA (Multipurpose Infrastructure for Network Applications)

Simple Server-side and Client-side APIs.

Optional multithreading support.

Maven2 support.

MOINC Server – Roadmap

The End Result…

“We have a highly scalable and loosely coupled

architecture for deploying Web Services on grid

environments.”

“Reliability can be achieved through message cloning.”

“Better performance can be achieved through message

splitting and aggregation.”

What We Did…

“MOINC is not just a product. It’s much more than that…

It resembles the inception of a whole new architecture.

An architecture which allows Web Services deployments

to scale beyond limits unimaginable.”
