Digital transformation requires

• 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

HYBRID CLOUD API Management DEVOPS & AGILITY

The Digital Transformation Challenge

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

Modernize business critical assets for the digital era with minimal

time, risk and cost

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 existingapplication 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

Application Discovery (AD) High Level Architecture

• AD:Analyze takes advantage of

Eclipse functionality for cross-

application analysis; analyzes

online applications plus batch

schedules/jobs/applications

• AD:Dashboard is web-based,

providing management

snapshots anytime, anywhere

• 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

AD is based upon an open, federated architecture, with all application information delivered and stored in a single, open repository

AD: Connect

The “engine room” - AD: Server

• 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 Real-

time, automatic synchronization with

current source code so developers

understand how functions are being

performed

Provides full lifecycle automation and ability to understand dependencies for all IT components in DevOps environments

Graphical Analysis & Reporting - AD: Analyze

• 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

Analyzes and correlates the relationships between application components to automate application understanding, mapping and interdependencies

Management Control – AD: Dashboard

• 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

Provides comprehensive, real-time view of the health and value of entire application portfolio throughout the enterprise

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

APIs: Scenarios for when I need to refactor my code first

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.

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
