14. Why is Brownfield Integration
Important?
• Reuse of existing systems
• Cutdown the time it takes for digital transformation
• Cut down cost
• Not all existing systems are replaceable
14

15. • Systems based on standard protocols
• Systems based on non standard or proprietary
protocols
• File based systems
• Systems that doesn’t provide any integration points
– Databases

16. Key Functionality Requirements
• Transformation
• Routing
• Orchestration
• Protocol Switching
• Parallel Processing

39. Brownfield Integration with Different
Types of Systems
• Integration with systems that talk in standard
protocols
• Integration with systems that talk in
non-standard/ proprietary protocols
• Integration with file-based systems
• Integration with systems that use databases
39

40. Integration with Systems That Talk in
Standard Protocols
Support for wide range of
standard protocols
• HTTP/HTTPS
• JMS
• AMQP
• FTP/SFTP/FTPS/SMB
• SMTP/IMAP
• MQTT
• KAFKA
• And many more
SMTP
HTTP
JMS
FTP
Websocket

42. Integration with Systems That Talk in
Non-standard/ Proprietary Protocols
• Built in support for well-known proprietary
protocols
E.g. SAP
• Easy to extend the functionality to introduce
new protocols

medium to integrate with other systems
• WSO2 Enterprise Integrator supports a wide
range of file transferring protocols such as FTP,
SFTP, FTPS, and SMB
45

46. File Handling Use Cases
Listen to a location, pick files, and invoke a web
API using the content of the files
File HTTP
Web API
Invocation
Existing Legacy
System

47. File Handling Use Cases
Expose a file-based system as an API over HTTP
protocol

48. Integration with Systems That Use
Databases
Expose databases or other data sources as
services
