What is IT resiliency?

Whether on-premises or in the cloud, your IT resiliency is your ability to adapt to planned or unplanned events while keeping services and operations running continuously. When you have the highest IT resiliency:

  • Data loss is not tolerated
  • Workloads run, even during an outage
  • Hardware, middleware and apps are continuously available
  • Disruptions are minimized and service levels are restored quickly.

What’s the risk?

of IDC respondents experienced a disruption in the past two years.

50 percent

of organizations could not survive a disaster event, IDC estimates. (1)

34 percent

of ITIC respondents say an hour of downtime could cost USD 1M to USD 5M+. (2)

Is your IT infrastructure resilient?

When mother nature strikes, the local electric grid fails, or human error/malice disrupts operations, your business is at risk for revenue loss, fines and reputational risk. Consider:

  • What is the probability of an outage?
  • What is the business impact per hour?
  • What is the opportunity cost?
  • How can you design your systems better?

Why IBM Z for resiliency?

IBM’s Z is in a class of its own: 83% of respondents said their firms achieved five and six nines – 99.999% and 99.9999% – or greater uptime.

Continuous availability

On private, public or hybrid cloud, IBM Z® offers superb qualities of service on- and off-prem. Customers report only 8.8 seconds of annual downtime; that’s 99.9999% uptime.(3) IBM Z® is designed to remain continuously available and speed reaction times with new technologies like AI, machine learning and containers.

Comprehensive disaster recovery

Disaster recovery on IBM Z® and GDPS® allows organizations to run services without disruption and rapidly resume mission-critical functions in the event of a disaster. The recovery time objective (RTO) is measured in hours and the recovery point objective (RPO) can be achieved in minutes after the disaster is declared.

Resiliency in hybrid cloud

As companies build hybrid cloud environments, their foundational services must run without disruption. Core systems must stay up, even during an unplanned outage. IBM Z® is designed to deliver the highest resiliency, availability and recovery capabilities in hybrid cloud environments, so you can meet the most stringent SLAs.

The highest cyber resiliency

You need integrated, intuitive security solutions to prevent cyber-attacks and provide levels of security from infrastructure to front-end. IBM Z® is designed to seamlessly encrypt 100% of application, cloud service and database data. According to analysts, IBM Z® encryption is 93% less expensive and 81% faster than competitors, while helping clients address compliance. (4)

Intelligent operations to keep your systems running

Are your IT operations running at their optimum? Not only should network, server, application and data layers be available, but they also generate data to help you identify complex problems.
