What is IT Architecture

IT architecture is a term that's often misunderstood. To put it simply, it's the process of designing and constructing IT solutions based on principles and guidelines. However, it's important to understand what a well-defined architecture deliverable should include.

A comprehensive IT architecture should cover and facilitate a high-level diagram of the IT components in an application, software and hardware design, integration with existing systems, software development methodology, technology standards, global technology interoperability, and consistent design and delivery of solution's IT capabilities.

It's also important to note that there are different types of IT architectures, similar to different levels of designing a building. The three main types of IT architectures are Enterprise Architecture (EA), Solution Architecture (SA), and Technology Architecture.

What is Enterprise Architecture?

Enterprise architecture (EA) is a strategic approach to designing and managing the IT systems and applications that support an organization's goals and objectives. It provides a blueprint for how the company's IT systems should be structured and how they should work together to support the business.

The EA framework includes all the applications and IT systems that are used within the organization, including core and satellite applications, integration platforms, web, portal, and mobile apps, data analytical tooling, data warehouse and data lake, and operational and development tooling, among others. The EA blueprint shows all IT systems in a logical map, providing a comprehensive overview of the organization's IT infrastructure.

The primary objective of EA is to ensure that the organization's IT systems are aligned with its business goals and objectives. It focuses on the business strategy and identifies IT solutions that can help achieve those goals, including innovation and digital enablement. To achieve this, an enterprise architect needs to understand both IT and business at a high level and be able to align the two.

EA is essential to clarify how business and IT align and how they support, enable, and facilitate each other. It improves consistency, coherence, and efficiency across the entire organization while meeting its current and future business and IT objectives.

In summary, enterprise architecture provides a strategic approach to designing and managing the IT systems and applications that support an organization's goals and objectives. It provides a comprehensive overview of the organization's IT infrastructure and ensures that IT is aligned with the business strategy to achieve business goals and objectives.
