Agenda

XAP 7.0: End-to-End Solution on a Single Platform
GigaSpaces eXtreme Application Platform (XAP) 7.0
An enterprise-grade application server for deploying and scaling Java and .NET applications under the most demanding and changing requirements.
Session high availability
Dynamic scaling
Application container
In Memory Data Grid
Async. Persistency

The Secret Sauce = Space Based Architecture (SBA)

A software architecture pattern for achieving linear scalability of stateful, high-performance applications

Inspired by
JavaSpaces & Yale’s Tuple-Space Model
Lessons learned from Next-Gen Internet services
Partitions the application and packages all middleware functions into one lightweight scalable unit
The data grid is the foundation
Linear Scalability

Typical Architecture – XAP 7.0
Dynamic LB Configuration
Managed Jetty Web Containers, Http Session on top of the Space
Interact with BL and Data via Space API, events, remoting or task executors
Business Logic and Data on top of the Data Grid
Partitioning and collocation for best performance and scalability
Async. Persistency
Proactive Administration

Agenda

R7.0 Themes
Even Better Data Grid Performance and Scalability
Performance improvements and better memory utilization
Dramatically faster read access for local caches and embedded clients
Mulitcore scalability
Improved Monitoring & Administration Capabilities
Major overhaul of the management GUI
All new GigaSpaces agent component
Comprehensive Groovy/Java administration & monitoring API
Deployment zones
Improved logging and troubleshooting capabilities
Simplicity & Usability
Simpler APIs - readById
Simpler and standard packaging
Simpler to configure in your IDE
Map/Reduce Grid Task Execution API – now also in .Net

7.0 Performance & Footprint Improvements
Restructuring of internal data structures (for better multi-core concurrency and lock-free read)
Refactored eviction mechanism
New local cache storage model
Results:
Significantly better concurrency in highly multithreaded environments (more details in next slides)
And, significantly reduced memory footprint for indexed fields:
XAP 6.6: 150-200 bytes per index field
XAP 7.0: 20-30 bytes per index field

7.0 Performance Improvements

Management GUI Overhaul
Accurately reflects the XAP runtime model
Includes:

Comprehensive monitoring of all layers: hosts, JVMs, processing units, web apps, spaces
Detailed information about the processing unit
Operate on all cluster layers:start and stop JVMs, deploy/undeploy PUs,relocate running instances, scale up/down

The GigaSpaces Agent
New runtime component
Think of it as the GigaSpaces daemon / service
Agent can start, stop and restart other runtime components:
GSM, GSC, LUS, Custom
Just start the agent, the rest will be done for you
Define global/local number of GSMs, GSCs and LUSs
e.g. 4 global GSMs, 2 local (per machine) GSCs, 2 global LUSs
Full control from the UI / Admin API

Administration & Monitoring API
Comprehensive monitoring of all layers
Event based programming model
Cluster wide statistics
Groovy bindings
Operate on all cluster layers – start and stop JVMs, deploy/undeploy processing units, relocate running instances, scale up/down

Administration & Monitoring API – Samples
Start GSM and GSCs, deploy, wait for the space to start:

Administration & Monitoring API – Samples
Monitor stats with Groovy closures:

Auto Scaling Your App Using the Admin API

Calculating average request rate (Groovy):
Scaling up (Groovy):

Task Execution API

Grid Processing API
New in 7.0 - .Net Support
Data-aware task processing
Automatic space-side resource injection
Code mobility (Java only)
Synchronous or asynchronous execution
Cluster wide execution (Map/Reduce)
Dynamic Language Support
Java:
.Net:

Case Study – Social Network Search Optimization
Fetch N degrees of relationship

MySql Solution:
Pre-warming social network data in memory
Single instance
~200 milliseconds to fetch 2 level (direct friends and friends of friends)

GigaSpaces Solution:
Store network in space, partitioned by userId
Use Executors to fetch network
> 1st degree uses distributed broadcast task (async)
2nd degree in under 5 milliseconds, 3rd degree in under 10 milliseconds

Deployment Zones

Tag GSCs with Zones
Can represent: DRP sites, racks, etc.
Restrict deployment to specific zones
Enforce different zones for primary and backup of same partition

Improved Logging
Based on customer feedback, extensible
Time based log file rollover policy
Daily, weekly, monthly
Log file naming:
2009-07-26~13.44-gigaspaces-gsc_1-uri01-5492.log
Improved log message format:
2009-07-26 14:02:57,375 processorPU.1 [1] INFO [org...PUServiceBeanImpl] - Stopped
Date & time
Component
Hostname
PID

Message

Simpler Packaging
No more shared-lib
Standard .war structure
Better class loader isolation
Simpler to get started with:
Reduced required jars
All under same dir

Agenda

Future Direction
Security (7.0.1)
Multi-data center support over WAN
Out-of-the-box SLA
Further improve manageability
Enhanced Querying Capabilities
Extend JEE support
EJB 3
JPA
