Business/IT Drivers for Shared Services Model for Data Management
Identifies the existing architecture services and discovers the overlaps and redundant architectures
within the organization and determines which among those can be standardized
Fills the void of the existing architecture services
Adopts best practices from within as well as outside the organization
Establishes enterprise/LOB standards, procedures and governance
Standardizes infrastructure, development methods and operational procedures
Creates repeatable processes, common business rules and components tailored to business needs
Lays down rules and policies on how information is conceived and distributed
Evaluates available tools and methodologies standardizing implementation
Helps to increase business agility
Enables reuse and faster time to market and increases ROI
Business Benefits from Shared Services Model for Enterprise Data Management

Culture, Politics, Leadership, and Operating Model: Many unique cultural, political and leadership factors like leadership styles, openness of
communication, degree of partnership between business and IT groups within the organization/LOB, degree of autonomy of business groups
within the organization/LOB, etc, define an organization/LOB and influence the effectiveness of a shared services EDM program
Business Linkage : Refers to the extent to which any EDM effort is linked to business strategy.
Senior Management Involvement : If a motivated senior management team exists, ways can be found to make the architecture process more
scalable; to overcome or adjust to tight budgets; or to market the shared services Program more effectively.
Business Participation: The successful data architect must master the process of navigating cultural, organizational, and political barriers and
achieving broad consensus across IT and business organizations alike.
Governance Structure and Compliance Process: The creation of a governance structure with appropriate senior-management, business,
and IT department representation as well as a compliance process is essential to a successful ongoing shared services EDM effort.
EDM Resources: EDM Effectiveness is strongly dependent on the competency and availability of the resources performing the activities of the
DAM process. This includes not only those directly involved in the process, such as the Architects, DBAs, Modelers; but also those involved in
governing the DAM and applying the DAM to their own efforts, such as project mangers, infrastructure engineers, and application developers.
Technology Investment and Procurement : The objective is to deepen the penetration of architecture content into daily, operational activities.
At a minimum, technology investment decisions, even nominal upgrades, must be guided by the shared services EDM process and content.

Why Centralized Metadata Management?
• A centrally managed metadata implementation also ensures that one
definition of data, locations, content and business rules is used by all
technologies and solutions
• Key Benefits
1. Lowers cost of ownership
2. Makes integration activities easier
3. Ensures data integrity
• Difficulties
1. Manual Intervention in E2E object linkages at various levels of
abstraction
2. Increased complexity in configuration management.
• The centralized metadata architecture ensures
• Standardized metadata across different systems.
• No replication of metadata across systems and hence no need for
synchronization of metadata across the components used.
• No need for maintaining bi-directional connections to be between
various tools for metadata exchange.
• Minimal effort in system integration.
• Optimal hardware resource requirements.

•Technique # 2: Active-Active setup (WD Fusion):
•Using WANDISCO third party tool.
•This is relatively new concept has not being used at TCS customer places, we can contact WANDISCO to provide list of customers who
have deployed in case needed.
•WD Fusion is a software application that allows Hadoop deployments to replicate HDFS data between Hadoop clusters that are running
different, even incompatible versions of Hadoop. It is even possible to replicate between different vendor distributions and versions of
Hadoop using WD Fusion.
•Some of the benefits of using WD Fusion are:
• RPO/ RTO is reduced to minutes than hours.
• Virtual File System for Hadoop, compatible with all Hadoop applications.
• Single, virtual Namespace that integrates storage from different types of Hadoop, including CDH, HDP, EMC Isilon, Amazon S3/EMRFS
and MapR.
• Storage can be globally distributed.
