Topic 7 -- EA & Tech Stacks
Topic Seven: Enterprise Architecture & Tech Stacks
Enterprise Architecture (EA): Analyzing, designing, planning, and implementing enterprise analysis to execute business strategies effectively. EA ensures that IT aligns with business goals.
Incorporates business processes and organizational design with IT programs, ensuring all components work together harmoniously.
Aligns business processes and technology, ensuring that technology supports and enhances business operations.
Important because enterprises undergo significant changes, and underlying technologies are complex. EA helps manage this complexity.
Connects complex technologies with desirable business outcomes, ensuring technology investments deliver tangible benefits.
Digital transformation plans include Cloud, AI, ML, Big Data, IoT, and RPA, all of which are integrated through EA.
EA starts with the current state and ends with the future state, providing a roadmap for transformation.
EA Pyramid: Illustrates the layers of EA.
Business: Business strategy defines the overall direction and goals.
Data: Data structure organizes and manages data assets.
Application: How applications process data, detailing the functionality of software systems.
Technology: Required software and hardware infrastructure supporting the applications.
EA Proposition: Delivers value by providing frameworks for understanding, planning, and informed decision-making, ensuring strategic alignment and effective resource utilization.
Ensures relevance of solutions by aligning technology with business needs.
Creates context through shared language and accountability, fostering collaboration and clear communication.
EA Use Cases: Examples include:
Enable growth by supporting scalability and innovation.
Ensure compliance with regulatory requirements.
Reduce complexity by streamlining IT systems and processes.
Platforms: Foundational technology used as a base for other applications, processes, or technologies, enabling extensibility and integration.
Critical for business transformation, providing a stable and scalable foundation.
Supports scaling and faster innovation, allowing businesses to adapt quickly.
Creates network effects, increasing value as more users and applications join the platform.
Technology Stacks: A set of technologies used to build and run an application, including front-end, back-end, and databases. Streamlines development and simplifies application building.
Front-End: Creates the look of the website, application, or program, focusing on user interface and experience.
Back-End: Creates the logic for apps or websites to work, handling data processing and server-side functionality.
Full Stack: Includes both front-end and back-end, providing complete application development capabilities.
Tech Stack Considerations: Factors when choosing a tech stack.
Consider application's purpose and plan for the future scalability.
Consider tech stack upkeep, including maintenance and updates.
LAMP Tech Stack: A common open-source web development stack.
Linux (OS): The operating system.
Apache (Middleware): The web server.
MySQL (Database): The database management system.
PHP (App Language): The programming language for web development.
