Our latest MuleSoft meetup in London covered both hybrid connectivity and SAP integration patterns. Real business scenarios for customer and sales order management - and how to turn these into a seamless API design.

9. THE CHALLENGE!
• Majority of enterprise data is still stored in on-premise applications.
• Moving all the legacy applications to cloud is not a viable option.
• Concerns around security and legal challenges warrants the need for an on-premise
architecture.
but…there is a need to expose enterprise data
securely with external vendors, cloud & SaaS
solutions, as well as API consumers. On-premise
applications need to have the capability to
integrate outside the enterprise.

10. IPSEC VPN
• Secure “always ON” connection
between sites.
• Relatively easy to manage and
one time setup requirements (in
most cases).
• If trusted end points then this
option suitable.
• Additional infrastructure may be
required on-premise to manage
secure connections.

Key Watchpoint: Security vulnerabilities that exist at the IP layer in the network could be passed to the on-
premise network across the IPSec tunnel.

11. PROXY SERVICES
• Reverse proxy exposed over the
internet as the single access
point which will perform
authentication
• Routing rules ensure that only
predefined systems are given
access to
• Ability to revoke access on an
individual application/partner
basis

Key Watchpoint: Higher effort in maintaining the service due to connection configuration requirements.

12. MULE ESB ON-PREMISE
• All connections routed via on-premise

• On-premise Mule application ensures
that only predefined systems are

• Ability to revoke access on an
individual application/partner basis
• Allows full abstraction of the legacy
applications.

INFORMATION.

User
Experience
• Analyse the AS-IS business process and identify
the Enterprise Functions and Data that are to be
exposed via an API
• Define the data model that should be used while
exposing the functions and information from the
backend system(s)
• Define the functions that will be responsible for
interacting with the backend system(s)
• Build a layer of abstraction between the
backend system(s) and the exposed services by
grouping the functions and information that
serve a specific process
• Build an orchestrated process layer that utilises
the defined functions, data and/or services.

15. INTEGRATION OPTIONS WITH
SAP NETWEAVER.
IDOC – Intermediate Documents. An SAP document format for transferring data within SAP and non-
SAP applications. IDoc works with both master data and transactional data. IDoc transfers are
asynchronous in nature and they use XML representation. There is an IDoc available to support most
of the business processes in SAP, and they are generally well supported across versions.
RFC – Remote Function Calls. A standard SAP interface for communication between SAP systems. The
RFC calls a function to be executed in a remote system. A function module in SAP can only be accessed
from an external system if its remote enabled.
BAPI’s – Business Application Programming Interfaces. These are essentially API’s written and
supported by SAP to enable integration between SAP modules and between SAP and third-party
applications. BAPI interfaces provide access to precise business application data and processes while
facilitating external SAP application programming communication. Each BAPI is assigned to an object
in the Business Object Repository and underneath it’s a remote function enabled Function Module.
ABAP Interfaces – With expertise, developers can write their own custom interfaces using ABAP. This
is the most direct option to integrate with SAP when dealing with bespoke requirements. The
disadvantage is that SAP doesn’t support these interfaces and they can present a problem at upgrade
time. Programs can be developed to consume external SOAP/REST services.
SAP NetWeaver – For SAP ECC, NetWeaver is the preferred tool for moving data and triggering actions
between SAP modules and third party software. The ABAP Workbench offers an environment where
one can develop, configure, publish, find, and call Web services. It enables the SAP Web Application
Server to act both as a server and client for Web services.
