What is a disadvantage associated with container technology?

One of the key disadvantages associated with container technology is that it can be time-consuming to manage, especially as the number of containers scales up. While containers are designed to be lightweight and easy to deploy compared to traditional virtual machines, managing a large number of containers often requires a robust orchestration tool such as Kubernetes.

With the complexity of microservices architecture that containers enable, tasks such as monitoring, scaling, and maintaining those containers can become quite intricate. This added complexity can lead to increased management overhead, requiring careful planning, monitoring, and sometimes a steeper learning curve for teams that are adapting to this technology. Consequently, organizations may find that as they adopt container technology, the time spent on configuration, resource management, and troubleshooting can increase, which can be a significant disadvantage if not appropriately addressed.

Other options present aspects that do not accurately reflect common challenges associated with containerization, such as costs, expertise requirements, and performance impacts. Containers are generally cheaper to run than traditional VMs, require specific expertise rather than less, and typically do not inherently decrease application performance.
