What is the correct sequence of the evolution of enterprise IT architecture?

The evolution of enterprise IT architecture generally follows a logical progression that reflects the increasing sophistication and integration of technology systems within an organization. The correct answer outlines this sequence accurately.

Starting with "Application Silo," this phase represents a time when different applications operate independently without much integration or sharing of data. Organizations often faced challenges related to data accessibility, duplication, and inefficiencies during this stage.

The next stage, "Standardized Technology," typically emerges to address the issues of the siloed applications. By adopting standardized technologies, organizations can enhance interoperability among their systems, which fosters improved communication and data exchange.

Following this, the "Rationalized Data/Optimized Core" phase emphasizes the importance of data management. Here, organizations strive to consolidate and optimize their data architecture, ensuring that data is not only accessible but also reliable and relevant. This step is crucial for effective decision-making and operational efficiency.

Finally, the transition to "Modular Architecture" reflects a mature IT environment where systems are designed to be flexible and scalable. This architecture allows organizations to adapt to changes in technology and business needs more rapidly while leveraging previously established technology standards and optimized data structures.

Thus, the correct sequence captures the logical development from isolated applications, through standardization and data optimization, to a
