Job Role Description / Target Audience
The Big Data Architect works closely with the customer and the solutions architect to translate the customer’s business requirements into a Big Data solution. The Big Data Architect has deep knowledge of the relevant technologies, understands the relationship between those technologies, and how they can be integrated and combined to effectively solve any given big data business problem. This individual has the ability to design large-scale data processing systems for the enterprise and provide input on the architectural decisions including hardware and software. The Big Data Architect also understands the complexity of data and can design systems and models to handle different data variety including (structured, semi-structured, unstructured), volume, velocity (including stream processing), and veracity. The Big Data Architect is also able to effectively address information governance and security challenges associated with the system.

Recommended Prerequisite Skills
Understand the data layer and particular areas of potential challenge/risk in the data layer
Ability to translate functional requirements into technical specifications.
Ability to take overall solution/logical architecture and provide physical architecture.
Understand Cluster Management
Understand Network Requirements
Understand Important interfaces
Understand Data Modeling
Ability to identify/support non-functional requirements for the solution
Understand Latency
Understand Scalability
Understand High Availability
Understand Data Replication and Synchronization
Understand Disaster Recovery
Understand Overall performance (Query Performance, Workload Management, Database Tuning)
Propose recommended and/or best practices regarding the movement, manipulation, and storage of data in a big data solution (including, but not limited to:
Understand Data ingestion technical options
Understand Data storage options and ramifications (for example , understand the additional requirements and challenges introduced by data in the cloud)
Understand Data querying techniques & availability to support analytics
Understand Data lineage and data governance
Understand Data variety (social, machine data) and data volume
Understand/Implement and provide guidance around data security to support implementation, including but not limited to:
Understand LDAP Security
Understand User Roles/Security
Understand Data Monitoring
