1. Description of Service

The Information Technology Division (ITD) service offering for Integration Services has recently been updated to include the Shared Application Infrastructure (SAI) initiative. The SAI program involves the use of Service Oriented Architecture (SOA) applications and the sharing of services between connected applications across the Commonwealth agencies. It is the objective of ITD to provide the Commonwealth of Massachusetts customers, business partners and Commonwealth constituents with a secure, efficient and cost effective data interchange service.

ITD is building an infrastructure which allows for a broader set of communication mechanisms that offer greater visibility into monitoring the environment. It is the goal of the SAI program to secure data sharing across agencies, enable efficient reuse and to deliver agile, flexible infrastructure and services.

This service includes:

Interchange offers Messaging, File Transfer functionality and a dedicated protocol gateway which enforces the Enterprise security policy. SAI Interchange Service (diagram link) offers the following capabilities:

• File Transfer - Provides a Managed File Transfer (IBM FTE / JSCAPE-FTP) which can be used for any new requests that are lightweight file transfers or for end-points that do not have messaging capability. File Transfer is also advised for specific protocol requirements, for example, S/FTP/S. For existing CommBridge interfaces where there is no requirement to upgrade to Messaging the use of File Transfer is recommended.

• Messaging - The Enterprise Messaging Infrastructure (MQ7 / Oracle) and Web Services (XML Gateway) exchanges data by a message passing both synchronous and asynchronous interactions between distributed computing processes. Messaging ensures the delivery of a message by using queues and providing the directory, security, and administrative services necessary to support the system. This solution is recommended for any new service and for existing CommBridge interfaces already using messaging.

• Security - Provides a dedicated protocol gateway which enforces security policy and ensures the secure transfer of data into and out of the SAI Interchange through the XML Gateway. Also includes the ability for transformation between disparate message formats, including binary, IBM MQ and XML.
  
  
  
• Legacy CommBridge - In light of the new Interchange Service offering, ITD will continue to support hosts that are currently running Legacy CommBridge. CommBridge is a service which supports asynchronous delivery between systems. It communicates with systems in a consistent manner, with integration and support for multiple platforms. It also has an encryption interface. For future new messaging service requests and existing CommBridge interfaces, the SAI Service offering is highly recommended.

Support services include:

• A Service Account Manager to answer any questions or concerns regarding ITD Services.
• Services offered through our Operations Office; including Change Management and customer access to incident management via email, phone (CommonHelp)
• The online COMiT service management portal
