Plan for disaster recovery, high availability, and scalability.
Evaluate and recommend hardware and network technologies.
Ensure infrastructure security and compliance.
Importance:
A well-designed infrastructure ensures high availability, performance, and security of core systems.
Example:
Planning and implementing a cloud migration for a financial services firm to improve scalability and disaster recovery.
2.5. Data Architect
Definition:
Data Architects focus on the structure, storage, and flow of data within the organization.
Responsibilities:
Develop data models, schemas, and standards.
Design data warehouses, lakes, and pipelines.
Ensure data security, privacy, and compliance.
Optimize data access for analytics and reporting.
Importance:
They enable effective data management, supporting analytics, reporting, and data-driven decision-making.
Example:
Creating a healthcare data architecture that consolidates patient records from various sources for research and analytics.
2.6. Security Architect
Definition:
Security Architects design the security framework and controls for organizational systems.
Responsibilities:
Develop security policies, standards, and procedures.
Design security architectures to protect data and infrastructure.
Conduct risk assessments.
Collaborate with other architects to embed security best practices.
Importance:
Protects the organization from cyber threats, data breaches, and ensures compliance with regulations.
Example:
Designing a multi-layered security architecture for a bank’s online banking platform.
2.7. Cloud Architect
Definition:
Cloud Architects specialize in designing and managing cloud-based solutions and infrastructure.
Responsibilities:
Design cloud migration and deployment strategies.
Select appropriate cloud services and deployment models.
Ensure cloud security, compliance, and cost-efficiency.
Optimize cloud architectures for performance and scalability.
Importance:
Enables organizations to leverage cloud benefits such as agility, scalability, and cost savings.
Example:
Designing a serverless architecture on AWS to handle variable workloads for a startup.
2.8. Business Architect
Definition:
Business Architects focus on aligning business strategies, processes, and organizational structures with IT systems.
Responsibilities:
Model business processes and capabilities.
Identify gaps and opportunities for digital transformation.
Collaborate with enterprise architects to align technology with business goals.
