and deploy Kubernetes can be difficult because it requires new disciplines and a lot of training to build the skills needed within enterprise IT teams .
Defining the right storage needs for Kubernetes can also create something of a headache . Kubernetes ’ initially favoured applications such as stateless network services and processes that only consume CPU , network and memory , and do not need any storage . Unfortunately , today ’ s requirements are rather more ‘ stateful ’ and most applications deliver value by manipulating data that must be stored somewhere .
Differences in architecture between VMs and containers also means the supporting ecosystem around the application and the containers needs to change . Monitoring , logging , security tools and especially data protection need to be reconsidered in order to support the container ecosystem effectively .
Most important of all , however , is the need to remain focused on applying the same levels of security and resilience previously delivered to
VM-based applications . For example , top-tier , customer-facing applications are generally protected with multiple data protection and disaster recovery solutions , while lower-tier applications would be protected with high RPO backups only , or not protected at all . Although Kubernetes offers some limited capabilities , enterprises may find limitations in its ability to deliver true endto-end protection and resilience .
