People is: the “Network effects”

<Insert Picture Here> “ In other words, the Web model provides a single, open, and unified information architecture that is consistent, easily consumed, extremely scalable, securable, very reusable, resilient, and highly federated.” Dion Hinchcliffe Founder, Hinchcliffe & Co.

Data Grid

Oracle Coherence Data Grid Provides a reliable data tier with a single, consistent view of data Enables dynamic data capacity including fault tolerance and load balancing Ensures that data capacity scales with processing capacity Data Services Mainframes Databases Enterprise Applications Real Time Clients Distributed in Memory Data Management Oracle Coherence Data Grid Tags: http portlet publishing webloigc portal igoogle widget Web services Web services

Provides a reliable data tier with a single, consistent view of data

Enables dynamic data capacity including fault tolerance and load balancing

Ensures that data capacity scales with processing capacity

Data Grid Uses Caching Applications request data from the Data Grid rather than backend data sources Analytics Applications ask the Data Grid questions from simple queries to advanced scenario modeling Transactions Data Grid acts as a transactional System of Record, hosting data and business logic Events Automated processing based on event Tags: datagrid caching analytics transactions events

Coherence: A Unique Approach Members share responsibilities (health, services, data…) Completely Peer-to-Peer No Single Points of Bottleneck (SPOBs) No Single Points of Failure (SPOFs) Linearly scalable to hundreds of servers by design No Masters / Slaves etc. Data Grid members work together as a team Tags: datagrid coherence members nomasters noslaves spf spb peer-to-peer

Members share responsibilities (health, services, data…)

Completely Peer-to-Peer

No Single Points of Bottleneck (SPOBs)

No Single Points of Failure (SPOFs)

Linearly scalable to hundreds of servers by design

No Masters / Slaves etc.

Data Grid members work together as a team

Partitioned Topology : Data Access Data spread and backed up across Members Transparent to developer Members have access to all Data All Data locations are known – no lookup & no registry! Tags: datagrid coherence members data access

Data spread and backed up across Members

Transparent to developer

Members have access to all Data

All Data locations are known – no lookup & no registry!

Partitioned Topology : Data Update Synchronous Update Avoids potential Data Loss & Corruption Predictable Performance Backup Partitions are partitioned away from Primaries for resilience No engineering requirement to setup Primaries or Backups Automatically and Dynamically Managed Write-behind Tags: datagrid coherence membersdata update

Synchronous Update

Avoids potential Data Loss & Corruption

Predictable Performance

Backup Partitions are partitioned away from Primaries for resilience

No engineering requirement to setup Primaries or Backups

Automatically and Dynamically Managed

Write-behind

Partitioned Topology : Recovery Membership changes (new members added or members leaving) Other members, using consensus , recover and repartition automatically No in-flight operations lost, no availability gap! Some latencies (due to higher priority of asynchronous recovery) Information Reliability & Continuous Availability are the priorities Tags: datagrid coherence recovery data

Membership changes (new members added or members leaving)

Other members, using consensus , recover and repartition automatically

No in-flight operations lost, no availability gap!

Some latencies (due to higher priority of asynchronous recovery)

Information Reliability & Continuous Availability are the priorities

Implements Map interface

Drop in replacement. Full concurrency control. Multi-threaded. Scalable and resilient!

get, put, putAll, size, clear, lock, unlock…

Implements JCache interface

Extensive support for a multitude of expiration policies, including none !

More than “just a Cache”. More than “just a Map”

Real-time filterable (bean) events for entry insert, update, delete

Filters applied in parallel (in the Grid)

Filters completely extensible

A large range of filters out-of-the-box:

All, Always, And, Any, Array, Between, Class, Comparison, ContainsAll, ContainsAny, Contains, Equals, GreaterEquals, Greater, In, InKeySet, IsNotNull, IsNull, LessEquals, Less, Like, Limit, Never, NotEquals, Not, Or, Present, Xor…

Events may be synchronous*

trades.addMapListener( new StockEventFilter(“ORCL”), new MyMapListener(…));

Features : InvocableMap Interface Execute processors against an Entry, a Collection or a Filter Executions occur in parallel (aka: Grid-style) No “workers” to manage! Processors may return any value trades.invoke( new EqualsFilter(“getSecurity”,“ORCL”), new StockSplit(2.0)); Aggregate Entries based on a Filter positions.aggregate( new EqualsFilter(“getSecurity”,“ORCL”), new SumFilter(“amount”)); Tags: datagrid coherence processors collection filter

Execute processors against an Entry, a Collection or a Filter

Executions occur in parallel (aka: Grid-style)

No “workers” to manage!

Processors may return any value

trades.invoke( new EqualsFilter(“getSecurity”,“ORCL”), new StockSplit(2.0));

Aggregate Entries based on a Filter

positions.aggregate( new EqualsFilter(“getSecurity”,“ORCL”), new SumFilter(“amount”));
