Module 1 Part 1

IT Architecture

IT Architecture

Provides a structured approach to designing applications on the cloud and on-premise that are scalable, resilient, and highly available.

Business Model

A company's strategy for creating value for customers and generating revenue.

Process Architecture

The architecture of all business processes, including customer engagement, product manufacturing, and new product design.

Organizational Architecture

Focuses on how the enterprise is structured in terms of locations, business units, and management.

Product Architecture

Allows a company to have commonality between product families to reduce production costs.

Business Capabilities

Key operations and functions designed to support the business model.

Reference Architecture

Guidelines on how to build software and integrate IT applications within an organization.

Integration Landscape

Ensures that multiple applications work together seamlessly within the organization.

Infrastructure Services

Provide hardware services like computational capabilities and storage services to support IT applications.

Cloud Native Applications

Applications designed to run directly on the underlying cloud runtime and managed by automated tools.

Software Layers

Refers to the hierarchical structure of software components, including applications, operating systems, hardware, and networks.

Application Architecture

Involves designing software applications with layered logical structures to separate user interaction, business logic, and data storage.

Presentation Layer

The top layer of the application architecture responsible for user interaction, including user interface components and presentation logic components.

Business Layer

Implements the business logic and workflows of an application, serving as an intermediary between the presentation layer and data layer.

Data Layer

Manages data storage, retrieval, and connections to external services, ensuring data integrity and availability for the application's functions.

Business Components

Refers to different functional units within an organization, such as human resources, sales, and planning, each responsible for specific tasks.

Business Entities

Represent the legal entities of an organization in various countries where they operate, including plants, headquarters, and distribution facilities.

Data Layer

Provides access to data within the system or from external sources, essential for supporting business functions and processes.

Data Access Components

Routines or capabilities within the data layer that retrieve, write, and apply logic to data, ensuring data security and integrity.

Service-Based Solution

Comprises multiple services communicating with each other to collectively perform functions within an application, following a standardized interface.

Service Interface

Acts as a facade exposing the business logic of an application to potential consumers, whether internal or external systems.

Message Type

Defines the format and structure of data exchanged between services, supporting different types of operations and logic implementation.

Cross-Cutting Functions

Include security, operational management, and communication protocols that span across different layers of the IT architecture to ensure system integrity and performance.
