Question

Critically evaluate various technology infrastructures and the challenges of managing them.

Answer 1

Technology Infrastructures

• Network functions virtualization - Software-defined networking provides increased data flow intelligence, and, automation. WAN, end-to-end implementation are rare. The focus is on moving from SDN to NFVs.
• Internet of things Looming security concerns delay projects, and, slow the overall effect of the internet of things.
• Hyper Convergence - Investment is required in both CapEx, and, OpEx infrastructure technologies. Legacy data centres will have to be re-worked to take advantage of a software-centric approach.
• Cloud - Cloud computing model for critical applications. Critical infrastructure services, legacy, and, proprietary applications have been migrated to the cloud.

Challenges of managing technology infrastructures

• Expenses may outpace funds even for healthy IT budgets. Consumption of IT resources should not result in over-purchasing
• Standards-based common framework for data analysis
• Meeting availability needs of the application - public, and, private cloud
• Knowledge for control of networks, and, systems
• The balance between availability, and, spending
• Data acquisition - One needs systems that can rapidly reconfigure, take into account changes in algorithms, to exploit idle cycles
• Increasing throughput using general purpose graphical processors, and, exploiting multi-core platforms
