Network Redundancy Planning
In many instances, redundancy is avoided in the IT world. However, redundancy can be part of the recommended planning process for networks and network security. In addition, many different techniques are used to harden a system. Keep these topics in mind as you research them to complete this week’s discussion.

Network Redundancy Planning
- Examine network planning and share what you find. Where is redundancy recommended?
- Explain what redundancies are recommended and why you agree or disagree with the recommendations.
- Examine the various techniques to determine where to apply redundancy, and select two techniques that you would recommend be used in your organization, as well as two that you would not recommend. Provide the rationale for your selections.
After reading a few of your classmate’s postings, reply to those from which you learned something new or to which you have something constructive to add. For example:
- Discuss what you learned.
- Ask probing questions or seek clarification.
- Explain why you agree or disagree with your classmate’s main points, assertions, assumptions, or conclusions.
- Suggest research strategies or specific resources on the topic.
Network Redundancy in IT Planning
Network redundancy plays a vital role in ensuring continuous system operation during outages or component failures. It involves duplicating critical components like routers, switches, and data paths. Redundancy is recommended in data centers, internet connections, and power supplies to avoid single points of failure. I agree with these recommendations because they increase network reliability and reduce downtime. Without redundancy, systems may crash, causing data loss and operational delays. Redundant internet connections ensure continuous access even if one provider fails. Redundant power supplies keep servers running during power outages. However, redundancy must be planned carefully to avoid unnecessary costs.
Redundancy Techniques: Recommended and Avoided
Two effective techniques I recommend are using dual internet service providers and server load balancing. These provide both speed and backup during service failures. Load balancing distributes traffic and prevents overload. On the other hand, I do not recommend redundant end-user devices or duplicating minor switches. These offer minimal benefit compared to their cost and maintenance needs. Each organization should evaluate its needs and budget before implementing redundancy. In summary, planned redundancy enhances security and performance. However, overuse leads to wasted resources. Therefore, organizations should prioritize critical systems and adopt redundancy where it delivers high impact and reliability.
