Why Is Resilience Important In Information Technology?

IT resilience is an organization’s capacity to sustain acceptable service levels when business activities, vital procedures, or your IT environment are disrupted. High availability is important to your firm’s success in this digital age.

Customers will not tolerate a downed website. You cannot afford to have an ERP, CRM, or other business-critical technology down. This is when a high level of availability comes into play.

To achieve IT resiliency, your firm must “check the boxes” on many different technologies and solutions, not the least of which are backup, disaster recovery, cyber resilience, and high availability solutions.

System resilience (also known as system resiliency) has been widely addressed as a crucial topic during the last decade, particularly in data centers and cloud computing.

It is also critical in cyber-physical systems, albeit the word is less typically used in that context. Everyone expects their system to be robust, but what does that entail?

As part of my work on developing resilience criteria for cyber-physical systems, I recently did a literature review of existing resilience standards and other papers.

According to my research, “resilience” is commonly employed casually, as though its meaning is evident. It has been given comparable, but sometimes uneven, definitions in those contexts when it has been defined.

If you want help with your IT resilience, this article provides you with all the required information.

Generally, a system is resilient if it continues to carry out its goal despite hardship. Being resilient is vital because, no matter how well a system is constructed, reality will conspire to disrupt the design sooner or later.

Residual software or hardware faults will ultimately cause the systems to fail to execute a necessary function correctly or achieve one or more of its quality standards. An accident might occur due to the absence or failure of protection.

An undiscovered or unresolved security flaw allows an attacker to control the system. An external environmental situation (such as a power outage or high temperature) will cause service to be disrupted.

Because of these unavoidable disturbances, availability and dependability are inadequate, and a system must also be robust.

It must withstand adversity and continue to offer service, perhaps in a degraded mode of operation, despite disruptions caused by unfavorable events and situations. It must also recover quickly from any damage caused by the disturbances. A robust system, like in the classic Timex commercial, “can take a battering and keep on ticking.”

The capacity of a system to safeguard its vital capabilities against interruption caused by bad events and conditions is referred to as resilience. No system is completely robust to all adversity; resilience is always an issue of degree.

Avoiding or averting adversity does not increase a system’s resilience. On the other hand, avoidance reduces the requirement for resilience since systems would not need to be robust if misfortune did not occur.

Importance Of IT Resilience

Resilience is the emotional fortitude that allows people to deal with tragedy, adversity, and hardship. Resilient people use their resources, abilities, and skills to overcome obstacles and setbacks.

People who lack resilience are more prone to feel overwhelmed or powerless and more inclined to resort to negative coping mechanisms.

According to a study published in the International Journal of Environmental Research and Public Health in May 2022, people with higher resilience, coping abilities, and emotional intelligence are more likely to have increased overall well-being and life satisfaction than those with lower resilience and higher life satisfaction.

Research published in the February 2022 edition of Psychology, Health & Medicine that polled 1,032 college students discovered that emotional resilience was associated with lower stress and higher overall life satisfaction during the early stages of the COVID-19 pandemic.

According to one study, persons who had previously tried suicide had considerably lower resilience scale ratings than those who had never attempted suicide.

Resilient people face stress, disappointments, and tough emotions, but they draw on their strengths and seek assistance from others to overcome obstacles and work through issues.

Sood argues that resilience enables individuals to accept and adjust to a circumstance and move on. “It’s the core power you employ to carry the burden of life.”

It might be challenging to be positive and find equilibrium during stressful situations. Being resilient allows us to shield ourselves from being overburdened by stress, predicts well-being, and can help us avoid developing mental health problems.

Resilience and positive emotions also promote physical health, such as cardiovascular health, improved immunity, and improved sleep quality.

Resilience facilitates healthy behavior and supports health-promoting practices, such as lowering the risk of excessive drinking, smoking, or drug use, which predicts better health in the future.

How To Build IT Resilience

After a disaster, your services must be restored in minutes with little data loss so that you may restart operations successfully. IT resilience begins with a good backup and recovery strategy. Documenting and testing disaster recovery strategies ensures you can recover swiftly if downtime happens. In addition to on-premises security, merging private and public cloud resources into a hybrid cloud may improve your organisation’s IT resilience while simultaneously lowering costs and resources. A hybrid cloud has several advantages.

Set up public cloud resources as a disaster recovery site that can enable failover if the production site is disrupted.

Zerto is industry-leading data protection and recovery solution that combines continuous availability, orchestration, and automation to speed the adoption of multi-cloud and hybrid-cloud environments.

The Zerto system provides simplicity, enterprise scale, and agile data protection, among other advantages:

Security Sensitive workloads remain in the private cloud, where sophisticated security and control are in place. Flexibility, When demand increases, computing and storage capacity expands into the public cloud.

Recovery from a disaster. The public cloud offers replication and recovery services. Efficiency, Intelligent workload placement efficiently distributes tasks across several settings.


As businesses scramble to digitise, IT departments must provide new services quickly while preserving operational stability. The urge to respond soon has a considerable detrimental influence on concerns of service resilience.

When a big retailer’s systems were down for many hours on a busy shopping day, it lost $5 million in sales. A software company’s revenue dropped 8% after a system problem disrupted operations. Businesses must deal with hundreds, if not thousands, of resilience incidents every year.

An unanticipated outage costs almost $9,000 per minute (or $540,00 per hour). Customer pleasure and employee productivity are both affected.
