Technology Architecture Using TOGAF

06-Technology Architecture : 

Technology Architecture in Enterprise Architecture (EA) focuses on defining and organizing the technology infrastructure, software, and hardware components required to support an organization’s business goals and applications. It acts as the blueprint for the IT environment and includes technology standards, protocols, and technical services necessary for systems and applications to operate effectively.

Key Aspects of Technology Architecture in EA

1. Infrastructure Components

• Servers

  • • Cloud: Which cloud will you select, and upon which criteria

    • On-Prime: Requires hardware configuration that meets application architecture, considering the growth and scalability.

• Storage

• Networks

• Security Model

2. Technology Standards and Protocols

Outlines technology standards (e.g., operating systems, network protocols) and design principles to ensure consistency, interoperability, and scalability across systems.

3. Application Hosting and Integration
   
   

Determines how applications will be hosted (on-premises, cloud, or hybrid) and how different applications will communicate (APIs, message brokers, etc.). Integration standards help maintain data consistency and streamline information flow.

4. Security and Compliance

• Encryption

• Access control

• Communication protocols:

  • • TLS

    • HTTP/HTTPS

• Data security: Encryption/Virtual private database

• SAST: Static application security testing, Using SonarCloud for example

• DAST: Dynamic application security testing, using Pen testing tools, like OWASP ZAP, Burp Suite 

• WAF: Web application framework

• Rate limiting: How to limit connectivity and monetize it.

5. Technical Services and Platforms
   
   

Includes shared services such as authentication, data management, and logging, as well as technology platforms like CRM or ERP systems. These provide reusable functions that are critical for applications across the enterprise.

6. Scalability and Performance
   
   

Ensures that the technology environment can scale with demand and meet performance expectations, which is essential for maintaining a high-quality user experience.

7. Stability and resiliency of the environment

Here, the focus is on building a disaster recovery model for applications that enable smooth operation

8. Disaster recovery 

With multi-region, backup and restore, DR environment
