Resource management: Cluster manager handle the allocation and management of resources such as CPU, memory, storage, and network across the nodes in the cluster. They track the available resources and efficiently distribute them among various tasks and users.
Workload scheduling: Cluster manager is responsible for scheduling jobs or tasks on the appropriate nodes within the cluster. They use algorithms and policies to consider factors like resource availability, workload balancing, and priority when assigning tasks to nodes.
Monitoring and reporting: Cluster manager continuously monitor the health, performance, and resource utilization of the cluster. They provide tools and interfaces for administrators to track the status of nodes, jobs, and resources in real-time. Additionally, they generate reports for analysis and decision-making purposes.
Fault tolerance and high availability: Cluster manager manage the redundancy and failover mechanisms in the cluster to ensure high availability and reliability. They detect node failures and automatically reschedule the affected tasks on other available nodes. They also handle the replication of data and services to maintain high availability.
Scalability: Cluster manager facilitate the dynamic scaling of the cluster by adding or removing nodes based on resource demands or other factors. They manage the integration of new nodes into the cluster and the redistribution of resources and workloads.
Load balancing: They distribute the workload across the nodes in the cluster to maximize efficiency and performance. Load balancing ensures that no single node is overwhelmed with tasks while others remain idle.
Cluster configuration and deployment: Cluster manager simplify the process of deploying, configuring, and maintaining the cluster. They provide tools for automating the setup, management, and updates of the cluster components.
Security and access control: Cluster manager implement security measures to protect the cluster from unauthorized access, data breaches, and other threats. They provide mechanisms for authentication, authorization, and role-based access control.
Data and storage management: They manage data storage resources within the cluster, ensuring data integrity, availability, and proper distribution. Cluster managers also handle the replication and backup of data to prevent data loss.
Integration with external tools and services: Cluster manager often integrate with various external tools and services, such as monitoring and logging solutions, storage systems, and identity providers, to enhance their functionality and extend the capabilities of the cluster.
