PM2 - Cluster Mode
https://pm2.keymetrics.io/docs/usage/cluster-mode/
The cluster mode allows networked Node.js applications (http (s)/tcp/udp server) to be scaled across all CPUs available, without any code modifications. This greatly increases the performance and reliability of your applications, depending on the number of CPUs available.

https://www.tp-link.com/us/support/faq/772/
EAPs under Cluster mode will negotiate with each other in the same LAN and one of them will be elected as the master EAP, while the others will become the member/slave EAPs, as shown in Figure 1. In this way the EAPs in the same subnet automatically form a group called cluster. All member EAPs in a cluster can synchronize their configurations ...
Redis Cluster Modes: Enabled and Disabled
https://docs.aws.amazon.com/whitepapers/latest/database-caching-strategies-using-redis/redis-cluster-modes-enabled-and-disabled.html
With Cluster Mode enabled, your Redis cluster can now scale horizontally (in or out) in addition to scaling vertically (up and down). In a Redis cluster with cluster mode disabled, you can have up to five read replicas in your replication group. Adding or removing replicas incurs no downtime to your application.
Cluster | Node.js v19.1.0 Documentation
https://nodejs.org/api/cluster.html
Clusters of Node.js processes can be used to run multiple instances of Node.js that can distribute workloads among their application threads. When process isolation is not needed, use the worker_threads module instead, which allows running multiple application threads within a single Node.js instance.
Replication: Redis (Cluster Mode Disabled) vs. Redis (Cluster Mode ...
https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Replication.Redis-RedisCluster.html
Beginning with Redis version 3.2, you have the ability to create one of two distinct types of Redis clusters (API/CLI: replication groups). A Redis (cluster mode disabled) cluster always has a single shard (API/CLI: node group) with up to 5 read replica nodes. A Redis (cluster mode enabled) cluster has up to 500 shards with 1 to 5 read replica nodes in each.

Cluster Deploy Mode in Spark: In Cluster Deploy mode, the driver program would be launched on any one of the spark cluster nodes (on any of the available nodes in the cluster). Cluster deployment is mostly used for large data sets where the job takes few mins/hrs to complete. spark-submit --deploy-mode cluster --driver-memory xxxx ........
Cluster and Fork mode difference in PM2 - Stack Overflow
https://stackoverflow.com/questions/34682035/cluster-and-fork-mode-difference-in-pm2
Cluster mode The cluster will only work with node as it's exec_interpreter because it will access to the nodejs cluster module (eg: isMaster, fork methods etc.). This is great for zero-configuration process management because the process will automatically be forked in multiple instances.

The default cluster mode is Standard. Important If your workspace is assigned to a Unity Catalog metastore, High Concurrency clusters are not available. Instead, you use access mode to ensure the integrity of access controls and enforce strong isolation guarantees. See also Create a cluster that can access Unity Catalog.
Clusters | MuleSoft Documentation
https://docs.mulesoft.com/runtime-manager/cluster-about
Clusters. A cluster is a set of up to eight servers that act as a single deployment target and high-availability processing unit. Unlike in server groups, application instances in a cluster are aware of each other, share common information, and synchronize statuses. If one server fails, another server takes over processing applications.
Spark Modes of Deployment - Cluster mode and Client Mode
https://techvidvan.com/tutorials/spark-modes-of-deployment/
Cluster Deployment Mode When the driver runs in the applicationmaster on a cluster host, which YARN chooses, that spark mode is a cluster mode. It signifies that process, which runs in a YARN container, is responsible for various steps. Such as driving the application and requesting resources from YARN.

Redis cluster specification | Redis
https://redis.io/docs/reference/cluster-spec/
In Redis Cluster, nodes are responsible for holding the data, and taking the state of the cluster, including mapping keys to the right nodes. Cluster nodes are also able to auto-discover other nodes, detect non-working nodes, and promote replica nodes to master when needed in order to continue to operate when a failure occurs.
From PM2 to Docker: Cluster Mode - Maxim Orlov
https://maximorlov.com/from-pm2-to-docker-cluster-mode/
The cluster module can only distribute traffic on a single machine, whereas a load balancer can distribute traffic to other servers. To get the maximum server performance and use all available CPU cores (vCPUs), you want to have one container per core. Starting multiple containers of the same application is simple.

Definition and Usage. The cluster module provides a way of creating child processes that runs simultaneously and share the same server port. Node.js runs single threaded programming, which is very memory efficient, but to take advantage of computers multi-core systems, the Cluster module allows you to easily create child processes that each runs on their own single thread, to handle the load.

Using PM2 and its cluster mode allows you to scale your applications in real-time. If you need more or less workers than currently available, use PM2's scale command and adjust the cluster size respectively: pm2 scale <app-name> <number-of-workers>. The scale command is only available for processes that already run in cluster mode.
