JavaSpaces Overview

• A shared repository available on the network to
  all applications in a system
• Distributed Shared Memory
• Tuple Space, Linda Project, Yale University
• Java Adoption by Sun as a Jini Service
• Simple JavaSpaces API write, read, take, and
  notify

AutevoSpaces SSI

• Single System Image (SSI) Clustered JavaSpaces
• IntaMission address the issue of resiliency
  through the Autevo High Availability option
• SSI clustered JavaSpaces behave as a single
  logical space in a completely transparent
  fashion

AutevoSpace SSI - Benefits

• Highly beneficial scaling characteristics
• Behind the scenes updates occur across the
  cluster asynchronously, while appearing
  synchronous to the JS client
• Reads occur on one process only
• Consequently read-loading can be balanced by
  adding more processes while update performance
  remains constant
• Does not rely on synch-on-commit at tx boundaries
• Less intrusive to application design
• Transactions are a significant overhead
  avoiding use of tx enables high performance
  algorithms to be used in an HA environment

11
AutevoSpace SSI - Implementation

• Proxy to JavaSpace is conventional
• Uses JavaGroups to broadcast updates
• JavaGroups provides guaranteed multicast or
  multiple unicast
• Updates occur asynchronously
• Operation only completes when all members have
  signaled completion
• New members are added dynamically
• Contact group and request membership
• Synchronization phase runs in background prior to
  joining
• Partitioning is available to improve performance

12
Adaptors in the SOA world

• Web Services UDDI, Jini Lookup Service- SOAP
• Create Composite Application
• Allow services to share information
• Single Sign-on
• Tib RV JMS
• Adds resiliency and reliability to the system
• Keeping the state in the Space
• Guaranteed Delivery and Persistency
• J2EE - JCA
• Distributed Cache
• Behaves as a bus between different versions , and
  vendors
• Provide High Availability and Persistency

13
Patterns Library and Tools

• Publish / Subscribe
• The JavaSpace can imitate the behavior of a
  messaging system
• FIFO
• LIFO
• Distributed Array
• Workflow
• Defined processes and policies for common
  workflow scenarios
• Autevo Profiler Autevo Explorer
• Deploy, Manage, Monitor, and Debugging Services

Business Challenge

• IT investment across industries has doubled in 8
  years
• Investment in applications to automate business
  function
• Further investment to automate interfaces
• Resulting systems are
• Focused on a functional need
• Massively heterogeneous (and will remain so)
• Complex and difficult to change
• 80 of budgets are focused on maintaining
  existing capabilities
• Challenge now is on end-to-end business processes
• Need to leverage existing systems
• Need to reduce complexity
• Need to deliver incrementally
• adding value in smaller increments with less risk
  and quicker payback
• Why is this challenge so elusive?

16
IT Integration Challenge

• Problem
• Proliferation of information across the
  enterprise
• Information is in different forms across the
  organisations
• Managing diversity of information
• accounts for over 70 of integration projects
• Current integration approaches lead to
• Complex rules and logic to manage diversity
• Information coupling
• Ripple effects of changes across the system
• What is the solution?

17
Model-Driven Integration - AutevoMDI

• An on-demand information integration platform
• Integrates disparate information assets with a
  common information model
• Modelling domain
• Reduces complexity, reduces coupling
• Model is virtual and on-demand
• Model is collaboration point for system
  components
• Model-driven approach enables
• New processes to added using standard modelling
  tools
• Processes to be changed and extended
• Back-end systems to be upgraded, migrated,
  consolidated

How it works- Design Business Process
Design Business Process
Design Domain Model
Map ExistingSystems
Deploy
Evolve

• Define a process that needs to be delivered
• No need to map a complete end-to-end process as
  things can be changed without disruption

Map Existing Systems

• By using Agents, each back-end system is mapped
  individually to the model.
• At no time has anyone had to understand all
  information across all the system that may be
  pertinent to the process.

• The process is then deployed with the model and

• Extend a process This usually involves
  extension or changes to the model and often
  includes the integration of new systems.
• Now add a new processes.

• Note that MDI provides a full object model
  information can be enriched, as the model holds
  logic and data.
• This gives tremendous flexibility and very
  significantly reduces the burden of integration.

AutevoMDI - Process Integration

• Why is this approach so powerful?
• Business need drives the integration
• Models are built to support the business need
• Complexity of systems shielded from the business
• Processes, applications, databases are de-coupled
• all collaborate via the model
• Why is AutevoMDI unique?
• Only with Autevo can the model be changed without
  disruption
• This capability uniquely enables the incremental
  approach

25
Data cleansing

• Solution
• Model the information required to support the
  process
• Map to back-end systems
• Develop processes that deal with dirty data in
  real-time
• Automated fixes
• User intervention triggers
• Benefits
• Process can launched immediately
• Data is cleansed on the fly

• Problem domain
• Processes that span disparate systems
• Different information in different forms
• Cleaning data before launching process is
• Difficult
• Data live and always changing requires
  shut-down
• Costly
• Very significant cost before value is perceived
  at the process level

26
