What is IT resiliency?

Whether on premises or in your hybrid cloud, your IT resiliency is your ability to adapt to planned or unplanned events while still keeping services and operations running continuously.

When you have the highest IT resiliency, your data remains available, your IT infrastructure stays operational, disruptions are minimized, and service levels are restored quickly.


A platform for cyber resiliency

Used by businesses of all sizes, from Fortune 100 companies to next-gen startups, IBM Z is an investment for a cyber-resilient hybrid cloud.

IBM z15™ solutions deliver up to 99.99999%* availability, reduce the impact of failure, speed recovery, and isolate workloads to help protect against internal and external threats.

Technologies and software for IT resiliency

Minimize the impact of disruption

Speed up the return to your pre-shutdown SLAs by up to 2X after planned or unplanned downtime.

Use a trusted execution environment (TEE)

Isolate workloads at granularity and scale and help protect them from internal and external threats.

Gather data to analyze workloads

Generate summarized activity of operating system, middleware and workload components for performance diagnosis.

Identify root causes across subsystems

Correlate, prioritize and view anomalous activity in data with a single user interface.

Trust in your OS

See what’s possible with a more secure and resilient operating system.

Run continuously

Learn about technologies that help IBM Z keep your workloads running.


What’s the cost of downtime?

In today’s world, where “always on” has become the status quo, downtime is increasingly expensive and unacceptable. Businesses must reinforce their IT resiliency to avoid lost revenue, regulatory penalties and damaged reputations.

Lost revenue

88% of businesses lose USD 300,000 per hour and 40% lose USD 1.5 million or more.¹

Regulatory penalties

Government regulation, monitoring and inspection add pressure to deliver continuous availability.

Damaged reputations

Customers expect 24x7 availability. If a digital service is unavailable, the backlash can be swift.

*99.99999% disclaimer: Internal data based on measurements and projections was used in calculating the expected value. The z15 servers must be configured in a parallel sysplex using z/OS 2.3 or above; GDPS management of data and middleware recovery across Metro distance systems and storage, including GDPS Metro Multi-site Workload and GDPS Continuous Availability; and DS888X with IBM HyperSwap. Necessary resiliency technology must be enabled, such as System Managed CF Structure Duplexing, Sysplex failure management and Capacity Provisioning Manager. Other configurations may provide different availability characteristics.
