2 Digital transformation requires HYBRID CLOUD API Management DEVOPS & AGILITY Maximize enterprise value by balancing the use of internal assets and external services at scale Expose business critical services through APIs as your platform agnostic language within the context of a hybrid cloud Modernize business critical applications to gain business agility Componentize them leveraging java, system APIs and Micro services Evolve applications and services at the speed of business Leverage a cross-platform DevOps solutions to gain necessary speed and agility

3 The Digital Transformation Challenge Modernize business critical assets for the digital era with minimal time, risk and cost 1. Many clients are risk averse and avoid modifying their aging business-critical applications 2. Changes are often manual and therefore error prone, relying on few employees with domain expertise 3. Applications are often poorly documented, resulting in increased risk and effort 4. Sizing change effort is difficult if the understanding of business-critical applications is limited 5. Ramping up new hires to work effectively with business- critical applications is often tedious

4 What does Application Discovery (AD) do? AD retrieves, correlates and analyzes all application components to provide in depth understanding AD automates aspects of the understanding, planning, execution and verification of all change activities Engineered to maximise the value and flexibility of existing application assets in a wide spectrum of use cases : Assessment and planning Cross applications dependencies Support & Maintenance Application quality improvements Upgrade planning and enhancement enablement Batch understanding Impact analysis Web services API enablement Automated technical Documentation Facilitates both internal, blended and outsourcing model

5 Application Discovery (AD) Unlock the value in your business critical applications Unlock Empower Appraise Rapidly analyze and visualize your applications to make changes quickly, safely and efficiently Improve productivity of new and existing resources through knowledge transfer and automated documentation Continuously assess and improve quality against consistent metrics and enforcement of coding standards

6 Unlock: Rapidly analyze and visualize the secrets of complex applications Analyze and visualize relationships between application components, data and jobs Understand the structure of your business-critical applications across languages and environments Reduce risk and time and increase quality of changes through visual impact analysis integrated with your IDE Synchronize EZSource with latest changes in your source code management systems for a single source of truth Reduce development change effort by up to 30%* Reduce project management by up to 50%* * Based on AD client surveys , guidance from industry analysts and industry reference frameworks

7 Empower: Improve productivity of your development resources Automate documentation, enable on-demand understanding, and aid sizing of change efforts Accelerate knowledge transfer through accurate, automated and on-demand documentation Rapidly size change effort through insightful root cause analysis Aid new team members through comprehensive, accurate and consumable application analysis within the IDE Reduce time to size change effort by up to 80%* Reduce time to document your system by up to 90%* * Based on AD client surveys , guidance from industry analysts and industry reference frameworks

8 Appraise: Improve quality through enforcement of standards and metrics Enforce coding standards and assess health of application portfolio through reports and dashboard Deliver higher quality code by enforcing coding standards through reports and easy-to-use web interface Assess progress towards componentization through trend analysis of program complexity and maintainability Gain insight into the health and evolution of the entire portfolio through customizable role-based views Reduce test-fix cycles by up to 50%* Improve application performance * Based on AD client surveys , guidance from industry analysts and industry reference frameworks

9 Application Discovery (AD) High Level Architecture AD is based upon an open, federated architecture, with all application information delivered and stored in a single, open repository AD:Analyze takes advantage of Eclipse functionality for crossapplication analysis; analyzes online applications plus batch schedules/jobs/applications AD: RDz IDE Integration Graphical Analysis AD: Analyze Reports Where Used Analysis AD: Dashboard Management control AD:Dashboard is web-based, providing management snapshots anytime, anywhere z/os 3 rd Party AD:Build and Connect provide certified integration to 3rd party tools for complete application data using an open repository platform as a single version of the truth for custom analysis, reporting and correlation DB2 CICS IMS SMF TWS Control-M CA Endevor CA Librarian ChangeMan PDS Natural Mainframe Agents AD: Build AD: Connect AD Application Repository PDF Excel JPEG XML Visio JSON CSV EMF

10 The engine room - AD: Server Provides full lifecycle automation and ability to understand dependencies for all IT components in DevOps environments AD: Server is the common platform for the product suite (including Analyze and Dashboard). It administers the environment and includes: AD: Build is used by administrators and super users to define and manage analysis projects, including defining and configuring the various parsers AD: Connect is a collection of connectors used for importing or exporting information in/out of the EZSource repository and ensures Realtime, automatic synchronization with current source code so developers understand how functions are being performed

11 Graphical Analysis & Reporting - AD: Analyze Analyzes and correlates the relationships between application components to automate application understanding, mapping and interdependencies All AD tools use this "single version of the truth" for analysis, reporting and correlation Operates across multiple languages and environments to produce consistent understanding and measurement Rich static code analysis functionality allows users to configure, define and manage own analyses through proprietary visualization layouts Cross platform analysis to visualize how mainframe and distributed applications are connected

12 Management Control AD: Dashboard Provides comprehensive, real-time view of the health and value of entire application portfolio throughout the enterprise Easy-to-use web based, graphic interface providing accurate, unified view of entire IT landscape Combines and correlates data metrics from EZSource repository with external data such as cost, service desk, performance and tracks over time Views and metrics are configurable by user role: Executive/Management, Development / Testing, Service/Support Configurable categories of application understanding: Overview, Inventory, Complexity, Quality, Performance, Correlations

15 Configuring and implementing AD Installation process typically 1 week Configuring, training and initial load 1 to 4 weeks Project organisation Typically 1 per application Dev / Test / Prod versions and historical as needed Self sufficient for administration and usage after implementation Potential for product enhancements by agreement Required from client: Platform / application knowledge during implementation Cross application communication methods

16 APIs: Scenarios for when I need to refactor my code first Application Interface Mixes UI and Business Logic Discover the flow of the application with AD, so UI and business logic can be teased apart. Once separated, new interfaces such as mobile, Web, or B2B can be added as new, loosely coupled components. Application Interface is Too Coarse Big monolithic applications drive up response times and MIPS for frequent bite-size requests (e.g. mobile chequing balance). Understand how to best break your monolithic application into smaller, loosely coupled components using AD. These loosely coupled components also becomes significantly easier, faster, and safer to incrementally change. Application Interface is Stateful Standard 3270 connection work well with complex, stateful connections requiring intense conversations between UI and business logic. For mobile, stateful connections are a nightmare. Understand how to re-design to stateless interfaces using AD Interfaces are appropriate Recently modernized applications, e.g. as a part of an SOA initiative. Appropriate size with clear delineation between UI and Business Logic.
