Agenda
The need for building platforms on top of Kubernetes
A platform in action
that will make your life easier when building platforms
Context:
Demo:
Tools:

The need for building platforms
• Kubernetes built-in constructs are just building blocks
• One single Kubernetes Cluster is not enough
• Learning Kubernetes is Hard
• Training large teams
• The CNCF landscape keeps growing

How a platform can help?
A platform can help with:
• Reducing the cognitive load from development teams
• Provide a self-service approach to consume complex tools
• Improve our software delivery practices, by paving the paths to production
‟A platform is a collection of services and tools
focused on enabling teams with a self-service
approach to get the tools that they need when
they need them.”
- @salaboy, 2022

How does a platform look like?
Platform
Platform APIs

Kubernetes Clusters
Cloud Resources
On-Prem Services
Virtual Machines

Let’s add a new feature
Platform API
Can I have a Dev
Environment?
Development

Sure you can, let me
create one for you …
App Dev Teams
Here, take the keys to
connect

Let’s request a new Development Environment

Let’s create a Function
and deploy it to my
new Development
Environment
I can be written in any
programming
language!
I can run functions because
the platform already
installed all the tools that I
need

Disclaimer:
I haven’t created custom Kubernetes
Controllers for the demos!

Crossplane
Platform Cluster
GKE Cluster
EKS Cluster
AKS Cluster
GCP Provider

AWS Provider
S3 Bucket
Cloud SQL
Azure Function

Create Cloud Resources using the Kubernetes APIs

Crossplane
Compose resources into higher-level constructs
<<My Environment>>
Platform Cluster
GKE Cluster
GCP Provider
Cloud SQL
my-environment.yaml
Blob Storage Cloud Function
Platform APIs

VCluster
• Isolated fully compliant API Server
• Automatic Sync of Resources
• To create a VCluster you just install a Helm Chart
Kubernetes
VCluster A
API Server

VCluster B

VCluster for isolation
Isolation without $$$

Crossplane + Helm + VCluster
Provision Virtual Clusters with Crossplane and Helm

Knative Functions
Developer Experience and Functions Runtime
• Knative Serving (in your Kubernetes Clusters)
• Scaling up and down based on traffic (down to zero)
• Advanced Traffic Management (for release strategies)
• Simplified user experience (less YAML)
• Knative Functions
• Focused on developer experience
• Supports templates and different programming languages
• Reduce the cognitive load on developers and let them focus on coding

Knative And VCluster
Using our resources wisely - VCluster Knative Plugin

ArgoCD
GitOps everywhere
• Sync configuration in Git to Kubernetes Clusters
• Avoid changing configurations manually to clusters
• Revert back changing by just reverting commits in Git
• Keep track of configurations changes

Recap
This is just an example
• But it is amazing how many people are using these tools to build
similar platforms
• A well-define Platform API can help you to pivot and change the
tools that you are using to implement your platform’s functionality
• Focus on developers experience and developers productivity
