= Defining cluster size requirements for an {ServerlessProductName} installation
|
|
|
|
To install and use {ServerlessProductName}, the {product-title} cluster must be sized correctly.
|
|
The minimum requirement for {ServerlessProductName} is a cluster with 10 CPUs and 40GB memory.
|
|
The total size requirements to run {ServerlessProductName} are dependent on the applications deployed. By default, each pod requests approximately 400m of CPU, so the minimum requirements are based on this value.
|
|
In the size requirement provided, an application can scale up to 10 replicas. Lowering the actual CPU request of applications can increase the number of possible replicas.
|
|
|
|
[NOTE]
|
|
====
|
|
The requirements provided relate only to the pool of worker machines of the {product-title} cluster. Master nodes are not used for general scheduling and are omitted from the requirements.

[NOTE]

|
====
|
|
The following limitations apply to all {ServerlessProductName} deployments:
|
|
|
|
* Maximum number of Knative services: 1000
|
|
* Maximum number of Knative revisions: 1000
