In the scenario shown in Figure 1-16, you would use automated operations facilities within a single LPAR to restart-in-place, restart on another LPAR within the sysplex, or restart in an alternate site leveraging GDPS (or another automated DR framework) for both planned and unplanned outages.

## 1.4.3 Security 

Data breaches are being reported at an increasing frequency for organizations large and small. Such breaches lead to a loss of trust for the organization and its customers. Organizations are challenged to secure their data, and also to show auditors and government regulators that customer data is secure (especially sensitive customer data that might be used for fraud or identify theft). As result, security is a major requirement for applications today. 

Organizations are adopting container technologies to containerize their workloads and make them easier to deploy and test. Also, these technologies enable the migration of application workloads from one specific platform to another without needing code updates. Additionally, organizations are required to provide a higher level of security for mission-critical and highly sensitive data. 

By building your container environment into zCX instances, you take advantage of the benefits from a hardware platform that includes specialized processors, cryptographic cards, availability, flexibility, and scalability. These systems are prepared to handle blockchain applications and also cloud, mobile, big-data, and analytics applications. 

It’s well known that IBM Z servers deliver in dustry-leading security and reliability, with millisecond response times, hybrid cloud deployment, and performance at scale. The world’s top organizations rely on this platform to protect their data with impeccable security to run applications workloads. 

Although you can deploy your container workloads in any other server, you gain even more security when you deploy your applications in zCX. zCX is a special appliance that prevents access to the zCX operating system by system administrators who have lower privileges and tightly focused roles. The inherent security features IBM Z servers that protect data results in
