Think about a company you know well. What would be an example of IT architecture at that company? An example of the IT infrastructure? What, in your opinion, is the difference between a decentralized architecture and a centralized architecture? What is an example of a business decision that would be affected by the choice of the architecture?

IT architecture refers to the blueprint that defines the structure, behavior, and essential components of an organization's information technology environment. For example, in a large retail company like Walmart, the IT architecture might include systems for inventory management, point-of-sale transactions, customer relationship management (CRM), and supply chain logistics. These components are interconnected through a defined framework that supports integration and efficiency.

In contrast, IT infrastructure encompasses the physical and virtual resources supporting IT operations, such as servers, networking hardware, data centers, and cloud services. For Walmart, the infrastructure includes data centers across the globe, cloud providers, and network equipment connecting stores and warehouses.

The key difference between centralized and decentralized architecture lies in control and distribution. Centralized architecture consolidates control into a single core system or location, facilitating uniform management but risking bottlenecks. Decentralized architecture distributes decision-making and data across multiple nodes, allowing greater flexibility and scalability but potentially creating integration challenges. Business decisions, such as launching new product lines or expanding into new markets, can be influenced by this choice. Centralized systems might limit agility in rapid decision-making, while decentralized architectures support localized control.

Allowing employees to bring their own devices (BYOD or BYOT) into enterprise systems raises significant security considerations balanced against operational benefits. On one hand, BYOD enhances employee flexibility, productivity, and satisfaction by enabling access to corporate resources via personal devices. On the other hand, it introduces vulnerabilities, such as data breaches, malware infections, and loss of control over corporate data.

For example, a bank’s policy might restrict access to sensitive customer information via personal devices to mitigate risks. Alternatively, companies may implement Mobile Device Management (MDM) systems to enforce security protocols on employees' devices, such as encryption and remote wipe capabilities. Additionally, using Virtual Private Networks (VPNs) can secure data transmission when employees connect remotely.

Three key reasons supporting controlled BYOD policies include safeguarding sensitive data from external threats, ensuring regulatory compliance (e.g., GDPR or HIPAA), and maintaining operational continuity. Given these factors, organizations should establish strict security measures, clear usage policies, and regular monitoring. While BYOD can provide benefits, the primary concern remains protecting company assets from cybersecurity threats.

Sony Pictures faced a severe cyberattack that compromised unreleased films and sensitive emails. Ignoring the political angle, a reasonable response to an anonymous internet threat involves assessing the credibility and potential consequences. Before canceling a film, I would require evidence of a substantive threat, a threat assessment from cybersecurity experts, and a comprehensive analysis of the risks involved.

If I were Sony's CEO, I would prioritize incident response planning, including cyber threat containment, data recovery, and communication strategies. For an online threat, collaboration with law enforcement and cybersecurity agencies would be essential. To enhance security, I would recommend implementing robust access controls, multi-factor authentication, encryption of digital assets, and regular vulnerability assessments.

If I also managed a chain of theaters, I would emphasize data protection measures such as secure digital rights management (DRM), secure data transmission protocols, and employee cybersecurity training. Protecting unreleased digital content would involve encrypting files, restricting access, and ensuring secure storage. By doing so, Sony could mitigate risks of leaks and cyber espionage, safeguarding its intellectual property and reputation.

If I were a hacker aiming to breach Sony's system, I might employ social engineering tactics to gain initial access, such as phishing to acquire login credentials. Exploiting known vulnerabilities in outdated or unpatched systems could further facilitate entry. Once inside, I would attempt lateral movement to access high-value targets, such as proprietary content or sensitive communications. Ensuring persistence and evading detection would be critical to maintaining access.

To prevent future attacks against Sony or similar firms, several critical security elements must be in place. First, implementing a comprehensive Security, Education, Training, and Awareness (SETA) program trains employees to recognize and resist social engineering attempts. Second, adopting advanced intrusion detection and prevention systems (IDPS) enhances real-time threat detection. Third, regularly updating and patching software minimizes vulnerabilities. Fourth, employing zero-trust architecture—where access is continuously verified—limits internal threats. Lastly, establishing strict access controls, data encryption, and incident response plans enable quick mitigation. Overall, a multi-layered security approach, combining technological defenses and human factors, is vital for safeguarding media corporations from cyber threats.

Total Cost of Ownership (TCO) accounts for all direct and indirect costs associated with maintaining an infrastructure over its lifespan. Besides initial purchase and operational costs, additional expenses such as maintenance, training, upgrade costs, and downtime must be considered. Disposal costs, often overlooked, include decommissioning hardware, data destruction, and environmental disposal fees.

In making comprehensive TCO calculations, other significant costs include energy consumption (electricity for powering and cooling hardware), support personnel salaries, licensing fees for software, and costs associated with future scaling or upgrades. Additionally, costs related to compliance and auditing, cybersecurity insurance, and potential penalties for data breaches are relevant. Hidden costs such as productivity losses due to system failures or lengthy upgrade processes should also be included to provide an accurate financial picture. Recognizing these factors helps organizations make better-informed decisions about infrastructure investments and long-term planning, ultimately reducing unexpected expenses and optimizing resource allocation.

Applying financial metrics such as Return on Investment (ROI), payback period, Net Present Value (NPV), and Economic Value Added (EVA) to information system investments depends on the context. ROI is most appropriate when evaluating the profitability of a project relative to its costs, especially for projects with clear financial benefits. The payback period is suitable for short-term investments where quick recovery of costs is desired.

NPV provides a comprehensive measure of an investment’s profitability by accounting for the time value of money, making it especially useful for large-scale systems with long-term benefits. EVA measures the value added beyond the required return, emphasizing the creation of shareholder value and is most relevant when assessing ongoing operational improvements and strategic initiatives.

Conditions favoring each metric include: ROI for straightforward, short-term projects; payback period for projects with urgent cash flow concerns; NPV for projects with long-term strategic importance; and EVA for investments aimed at maximizing shareholder value and sustainable growth. Ultimately, the choice depends on the specific financial environment, risk appetite, and strategic priorities of the organization.
