SOA Governance

The Opportunity: Open & Agile Enterprise IT Infrastructure


Enterprise IT has – to a great extent – standardized on Service Oriented Architecture (SOA). In a SOA-based infrastructure, applications are opened up using XML, SOAP interfaces and – increasingly – RESTful APIs. Exposing application functionality and data as reusable Web services makes it quicker and easier for enterprise architects and developers to repurpose existing IT investments. It also enables connectivity across the enterprise and out to external departments, partners, customers, developers, cloud services and mobile devices.


The Challenge: Securing & Managing SOA -Based Infrastructure


Exposing enterprise IT assets as Web services creates a range of security and management challenges. Attempting to control, monitor and adapt SOA by applying IT rules to individual services is inefficient and unsustainable. Therefore, most organizations adopt a centralized, policy-driven governance model. But without the ability to control and audit how policy gets deployed and enforced at runtime, there is no way to ensure consistent security, adherence to business rules or compliance with regulatory requirements.


The Solution: Centralized Governance with a SOA Gateway


In order to effectively apply a policy-based approach to IT governance in a SOA-style infrastructure, it is necessary to create a central point where policies can be efficiently composed, managed and enforced. This can be achieved by deploying a full-functioned, policy-driven XML/SOA/API Gateway able to secure exposed interfaces, translate between protocols and generally manage the flow of data between enterprise Web services and out to the consumers of these services.


The Layer 7 Value:  The Industry-Leading SOA Governance Solution
