In this post we are going to take a look at the differences between Tanzu Community Edition and Platform9 Managed Kubernetes Free Tier. As a complement to Platform9 Managed Kubernetes and Tanzu Community Edition, this is a list of notable features between the two products.
|Feature / Activity||VMware Tanzu CE||PMKFT|
|Scaling restrictions||No||Up to 20 nodes w/o actual validation on the number of nodes being attached|
|Hosted Sandbox||Limited to 15-minute workshop for trying CE, which provides pre-created k8s cluster and tutors about basic kubectl commands.||Read-only sandbox for a quick tour of PMK UI.|
|Suggested minimum to run a local cluster||x86 architecture|
6 GB RAM
15 GB disk
16 GB RAM
30 GB Disk
|CLI||Tanzu CLI has more functionality than what is in the UI wizard.|
Had to install Tanzu CLI dependencies manually.
|PF9 doesn’t have a CLI to control the product but does have a CLI to onboard/manage cluster nodes (pf9ctl). Which has a self-contained install (for dependencies).|
|Onboarding nodes / creating cluster with Docker||Supports Docker-based work for bare-metal machines. Supports Mac, Windows, and Linux.|
No resource pre-requisites checker is implemented, which introduces the possibility of failures after going ahead with the installation.
Installation takes a huge amount of time. The errors were not clear.
|Does not support Docker based deployment. Supports deployment on VMs / BMs.|
In case of error, an appropriate log location is provided.
|UI||Minimal UI, mainly to show installation progress. Mimics CLI output.|
UI is started and accessible only after executing a Tanzu CLI command. Not readily accessible.
|Full-fledged UI with interactive capabilities.|
|Infrastructure providers||Hypervisors: vSphere|
Cloud providers: AWS and Azure
|Hypervisors: anything supporting OVA format|
Desktop: Linux VMs, baremetal
Cloud providers*: AWS, Azure
*also importing clusters from AKS, EKS & GKE.
|Creating a cluster with AWS||No IAM checker for checking policies for AWS account implemented.|
Does not work out of the box. AWS CLI has to be installed.
|IAM checker is part of pf9ctl, and can also be run from Mac & Windows machines. It provides clear requirements of role permissions/policies and compares existing policies with required ones.|
pf9ctl does not support creating clusters using cloud providers. Need to do it via UI.
|Available apps||These packages are available for ready deployment:|
Prometheus, Grafana, Cert-Manager, Ingress Controller (Contour), external DNS, Fluentbit, Gatekeeper, Harbour, Knative, CSI, Multus CNI, Velero (disaster recovery)
|App Catalog currently has these apps:|
NGINX Ingress Controller, Cert-Manager, FluentD, Fluentbit, hostpath.
Also has add-ons (infrastructure apps) like Prometheus, Grafana, MetalLB etc.
|CNI||Default: Antrea||Default: Calico|
|Community Support||Slack channel in Kubernetes workspace. Also supports Google Groups.||Dedicated slack workspace.|
|k8s versions supported|
(as of this publication)
|Binary size||Tanzu CLI: 34 MB||pf9ctl: 41 MB|
|Code open sourced?||Yes for both Tanzu CLI and Tanzu backend||No|
