Redundancies: What Are They and Why You Need Them in Your Business Footprint
Picture it: a massive outage lasting over 24 hours, disrupting 911 operations, ATM withdrawals, and hospital records. Now picture this happening to your network or infrastructure. This very real and very costly scenario happened when CenturyLink went down in December 2018. To think that it couldn’t happen to you and your business would be a serious mistake. The internet can go down. It is paramount to have a redundant network service in place, as well as have document business continuity and disaster recovery plans in place.
What Are Redundancies and Why You Need Them
Now regarding the above scenario, what and how could redundancies help if the outage had affected you? A redundancy works by having multiple channels of communication or power within your network as well as your infrastructure. In a way, redundancies are like insurance against failures. By ensuring multiple paths of connection, should a single path be lost, it would not make a significant impact because ultimately your connection would switch to another source.
When reviewing the financial, technical, and public relation aspects of a possible severe event to your business, it’s a no-brainer to make sure you have redundancies included within your enterprise’s footprint. If not familiar with redundancies and the type that could be implemented to safeguard you against future failures, continue reading below.
- Network: Redundant links and network equipment(routers and switches). Should main communication go down, the servers will
use backuplinks to keep the business online.
- Physical: Back up your utilities, such as power and water.
- Facility: Set up
backupsite for failover. If one location goes down, the other location can handle the entire business’s infrastructure.
It is important to note that redundancies should be put into place to deal with MIT (Maintenance Injected Trouble), which is one of the key causes of ISP outages. Consider outside cable plants with circuits on the same bundle, but then have redundant power to the rack circuit overload. This will aid in backhoe failures, technician trips, or accidental unplugging for both redundancies.
Implementation of redundancies within a network or infrastructure is necessary for maintaining availability. However, when used in excess, they can become a drain on bandwidth and overall performance. It is very easy for a network to be overly architected. When planning and implementing redundancies, the key is to have experienced professionals help your business. They will create backup paths built for efficiency, availability, and speed. Additionally, they will design and consider current failing paths, as well as build redundancies to fit exact pain points. Services like SDWAN and 4G LTE backup ensure resilient connectivity for businesses of all sizes. With today’s technology possibilities, there is no reason for a business to ever lose connectivity. Redundancy options are cost-effective and easy to implement, as you can see below.
Not only does
- Cost-effective compared to conventional WAN(Wide Area Networks).
- Relies less on proprietary devices to transmit data.
- More versatile and faster when delivering SaaS functionalities.
- Robust and scalable because of its rules-based automation.
4G LTE Connectivity
There are three main ways to set up failover through 4G LTE connectivity for redundancy. Each has its own unique benefits in certain circumstances:
Overlay: Using a router that converts a 4G LTE signal to Ethernet, which provides the location’s traditional wired-line router a second “wired” WAN connection instead of one.
Router and LTE: VRRP(Virtual Router Redundancy Protocol) enables a third failover option. Internet and router failover simultaneously. VRRP is a layer 3 protocol, which means it provides automatic default gateway selections to an IP network.
