8WebSphereTechnical White PaperIBM SoftwareRuntime server environmentThe IBM Worklight Server●● The Java-based IBM Worklight Server is a scalable gatewaybetween apps, external services and the enterprise. Theserver helps facilitate encrypted communication, back-endconnectivity, data manipulation, authentication, analytics,private cross-platform application store and operationalmanagement functions that are supported by a variety ofsecurity features. Server-side entities that affect the behaviorof the IBM Worklight server are represented in the studio’sproject tree, including configuration files, authenticationintegration code and more. From the IBM Worklight Studio,developers can save under a unified project all inter-relatedclient and server code and resources in their source controlsystem. Server configuration artifacts are automatically builtby the Worklight Studio in to a web archive (WAR) file. Thisfile can then be deployed on a standalone server for collabo-ration or test purposes.●● The IBM Worklight Server can be deployed to a widerange of hardware and operating system environments.Organizational teams that deploy the server to anIBM PureApplication™ System on Intel or Power canapply patterns of expertise. Use the IBM Mobile Applicationpattern for PureApplication System to configure and managea scalable and cloud-ready mobile server infrastructure.The IBM Worklight Server can:●● Provide adapter technology that connects to a variety ofenterprise information systems over widely used integrationtechnologies, such as Simple Object Access Protocol (SOAP),representational state transfer (REST), Structured QueryLanguage (SQL), Lightweight Directory Access Protocol(LDAP) and more. In addition, IBM Worklight provides aspecial IBM Cast Iron® adapter.●● Enable multisource data mashups to efficiently integrateseveral data streams into one and serve it to the applicationuser. Multisource data mashups are not only an effective wayof optimizing data delivery to the mobile user, but alsoreduce overall traffic in the system.●● Enable developers to add custom server-side logic that isnecessary for delivering back-end data for mobile consump-tion. This helps distribute processes between the client andserver and helps address data-security regulations within theorganization.●● Provide flexible security architecture with server-managedsecurity challenges, delivering more-robust protection.●● Integrate with the corporate authentication infrastructureto help secure application and data access, in addition totransaction invocation. The IBM Worklight authenticationinfrastructure is flexible enough to support different types ofauthentication—from multifactor or multistep login processesto non-interactive single sign-on (SSO) integration. You canalso expect offline authentication of users to increase appavailability. Furthermore, the IBM Worklight Server simpli-fies the integration with HTTP-based services that requireauthentication. Integration with Kerberos, Windows NTLAN Manager (NTLM), Basic and Digest authenticationcan be more-easily achieved by simple configuration of theHTTP adapter, without the need to write server-side code.The server also supports device-based application SSO,enabling apps to be automatically authenticated if an existingauthenticated session is already available through the samemobile device.●● Integrate with IBM WebSphere® security functions byproviding authenticators and login modules to leverageWebSphere security configuration and settings.●● You can employ standard and proprietary securitymechanisms to help prevent attacks.●● More-easily scale to support hundreds of thousands of usersand multiple applications through physical clustering.●● Provide app-deployment and version-control features that aremanaged and accessed by the IBM Worklight Console.●● Be integrated with IT monitoring and performance manage-ment systems that verify the vitality of the IBM WorklightServer and the services that it provides to applications.●● Automatically collect user-adoption and usage data forauditing and reporting purposes and gain access to customconfiguration of reporting metrics. Raw data can be more-easily exported for further analysis by the different businessintelligence tools used by the organization.
9WebSphereTechnical White PaperIBM SoftwareThe IBM Worklight Application CenterThe IBM Worklight Application Center enables companyteams to set up an enterprise app store to help govern the dis-tribution and management of pre-release and production-readymobile applications. Administrators can make the most ofexisting authentication frameworks, including ACL and LDAP,to manage app distribution by department, job function, geog-raphy and other schema. Employees who access the ApplicationCenter from their mobile devices will only see the mobile appsthat they are allowed to download. Employees can rate appsand provide feedback that can be considered for futureenhancements.For development teams, the Worklight Application Centerprovides a convenient way to distribute pre-release software todevelopers and testers. Feedback can be organized by deviceand by version to quickly isolate and resolve defects, whetherthose defects are device-specific or version-specific. TheApplication Center can also integrate with software-buildprocesses to automate the distribution of the latest releases toproject teams, accelerating the develop-test-debug cycle.The Worklight Application Center provides:●● Administrators with improved governance over the distribu-tion of mobile apps throughout the enterprise;●● Employees with easier access to the latest apps that areneeded by their department or job function and that areoptimized for their device;●● Developers with an easier way to distribute mobile buildsand to elicit feedback from members of development andtest teams.The IBM Worklight ConsoleThe IBM Worklight Console is a web-based user interfacethat is dedicated for the ongoing administration of theIBM Worklight Server and its deployed apps, adapters andpush-notification services.

Improperaccess can result in information being altered, destroyed or mis-appropriated, or can result in misuse of systems to attack others.Without a comprehensive approach to security, no IT system orproduct should be considered completely secure and no singleproduct or security measure can be completely effective in pre-venting improper access. IBM Worklight systems and productsare designed to be part of a comprehensive security approach,which will necessarily involve additional operational proceduresand may require other systems, products or services to be mosteffective. IBM Worklight does not warrant that systems andproducts are immune from the malicious or illegal conduct ofany party.System requirementsProduction environmentThe IBM Worklight server can be installed on the followingoperating systems:●● AIX●● HP-UX●● Red Hat Enterprise Linux (RHEL)●● SUSE Linux (SLES)●● Oracle Solaris●● Microsoft Windows ServerThe server requires the following databases to store metadataand cached back-end data:●● Derby●● Oracle●● MySQL●● IBM DB2®The IBM Worklight server can run on the followingapplication servers:●● Apache Tomcat●● IBM WebSphere Application Server (and NetworkDeployment) version 7.0 and higher (including the providedWebSphere Application Server v8.5 Liberty Profile)The IBM Worklight Server can be clustered to achieve highavailability and scalability. In such cases, a load balancer isrequired. This can be any commercial load balancer, softwareor hardware, which supports “sticky” sessions. The load bal-ancer can optionally act as a reverse proxy and as an SSLaccelerator.
