What are the disadvantages of containerization technology?

Main disadvantages of containerization technology:

• Incomplete isolation: containers share the host kernel, so the level of isolation is lower than that of virtual machines, which can lead to security issues.
• State management: containers are inherently stateless, which complicates handling state and requires additional infrastructure for data storage.
• Network configuration complexity: setting up networks and interactions between containers can be complex, especially in scalable systems.
• Resource intensity with a large number of containers: despite being lightweight, a large number of containers can put load on the system.
• Dependence on orchestrators: managing containers in production often requires the use of complex orchestration systems (e.g., Kubernetes), which increases support complexity.
