The scenario describes a "noisy neighbor" problem, where one application consumes a disproportionate amount of shared cluster resources, negatively impacting others. In Kubernetes, the standard mechanism to enforce fair resource usage and prevent this issue is by using ResourceQuotas and LimitRanges. ResourceQuotas constrain aggregate resource consumption per namespace, capping the total CPU and memory a team can use. LimitRanges enforce resource requests and limits on individual pods within that namespace, ensuring no single workload can monopolize resources. This directly mitigates the problem described.

B. Setting up Network Policies: Network Policies control network traffic flow between pods. They do not manage or limit the consumption of computational resources like CPU or memory.

C. Configuring RBAC: Role-Based Access Control (RBAC) manages user permissions—what actions a user can perform on cluster objects. It does not control the quantity of resources those objects can consume.

D. Implementing Continuous Deployment (CD): CD is a software development practice for automating deployments. It is a process methodology and has no built-in capability to manage or limit cluster resource allocation.

1. Kubernetes Documentation

"Resource Quotas": "A resource quota

defined by a ResourceQuota object

provides constraints that limit aggregate resource consumption per namespace. It can limit the quantity of objects that can be created in a namespace by type

as well as the total amount of compute resources that may be consumed by resources in that namespace."

URL: https://kubernetes.io/docs/concepts/policy/resource-quotas/

2. Kubernetes Documentation

"Limit Ranges": "A LimitRange is a policy to constrain resource allocations (to Pods or Containers) in a namespace." This works in conjunction with quotas to manage resources at a granular level.

3. Nutanix Karbon Documentation

"Creating a Kubernetes Cluster (Karbon UI)": While Karbon simplifies deployment

it operates on standard Kubernetes principles. Resource management is a fundamental Kubernetes concept applied to any Karbon-deployed cluster. The solution lies within Kubernetes constructs

not a Karbon-specific feature distinct from them.

URL: https://portal.nutanix.com/page/documents/details?targetId=Karbon-v28:kar-karbon-cluster-create-ui-t.html (This reference establishes that Karbon deploys standard Kubernetes

to which the above Kubernetes documentation directly applies).
