System Design
High Level System Design
The overview shows that our OX AppSuite system will consist of several components:
- HTTP Balancer
- Accepts user requests and decides which part of the OX Middleware should handle them
- OX Middleware
- The central logic layer that handles the incoming requests
- Control Panel
- Used for creation and administration of users (not delivered by OX)
- Mail Server
- Used by the middleware to receive and send e-mails (not delivered by OX)
- SQL Server
- Used by the middleware to e.g. store pim objects
- File Server
- used by the middleware to store documents and files
Middleware Details
The middleware itself consists of many modules whose functionality is either exposed via the HTTP_API or used internally. We have identified three blocks that should be grouped together and considered as logical components when planning the hardware layout and sizing of your infrastructure.
- Groupware
- definiton
- Documentconversion
- definition
- Synchronization
- definition
Component mappings in HTTP Balancer
The logical components mentioned above can be found again in our default Apache configuration which is distributed as part of the open-xchange-core package and located at /usr/share/doc/open-xchange-core/exapmples/proxy_http.conf.gz
You can find the wikified version at AppSuite:Grizzly#Apache_configuration
For each of the components we set up a balancing Proxy container so you can scale each of those components according to the number and demands of your users.
- Proxy balancer://oxcluster
- The members of this balancer container are responsible for handling general groupware requests
- Proxy balancer://oxcluster_docs
- The members of this balancer container are responsible for handling document conversion and thumbnailing requests
- Proxy balancer://oxcluster_sync
- The members of this balancer container are responsible for handling only USM, EAS and DAV synchronization requests
