By data plane, I meant the application data flow itself: code, runtime, OS, app data storage, app data connectivity (i.e., networking).  Models and policy are important aspects that can blur lines between data/control plane, but typically I see them more associated with the control plane because they usually direct how deployments occur in the data plane and how the data plane behaves (e.g., your segmentation scenario).  There may be situations where model/policy is more closely aligned to the data plane – I’m not seeking a rigid definition.

 

With respect to how networks are/not segmented between management and data, this is something I would expect the control plane policy model to allow for customer preference and not force either way. 

 

I agree with setting up a problem statement to define the ref arch context.  However, to the extent that a problem statement becomes a dictionary definition of what we’re trying to solve, it can become a protracted charter-defining type of process.  We might do both in parallel to not gate progress on the ref arch.  Disconnects can be resolve as the discussion unfolds.

Using the airport analogy, airplanes and airports are an orthogonal to air traffic control, baggage routing, etc.  Back to our world, it's the difference between data and control planes. 

 

I'd like to suggest that our reference model make clear the management/control plane in addition to the data plane as depicted in the landscape doc.  Craig's original diagram blended the two together, which is useful because there is much work to be done in both areas.  Column 'C' has some thoughts in this area, though unfinished.

 

CNCF can at least define the boundaries and functions users should be aware of in how the application/infrastructure stack is deployed, configured, and managed.  Further, we can facilitate interoperability in the control plane.

 

If there are no violent disagreements, I'll put up a strawman.

The approach I've been taking on this has been from a slightly different perspective. Most definitions have started with the infrastructure and I'm starting from the application and working backwards.

Using a combination of the power company utility model and the airport "separation of concerns" model of Air traffic control and ground control, I've been defining the roles of a) An independent application or specialty platform, b) a cloud native application fabric and c) an infrastructure substrate.

The premise is that applications decompose into segments, each of which distill into a finite set of application workload patterns. These patterns align to composition, distribution and execution models which provide the characteristics and behaviors each specific pattern requires. Simply put, the jobs decompose as follows:

1)  The application developer composes and describes the application
2) The app fabric recognizes the pattern, determines the best deployment pattern, transforms the workload and shops it for resources across a syndicate of infrastructure substrate providers (and technologies).
3) The infrastructure substrate executes the workload reliably at a local provider level

The fundamental shift notes that a cloud native app fabric scales business and technical functions implemented via software. As such, it can recognize demand using higher order indicators specific to functionality as opposed to traditional CPU, memory etc. As such, we align resource needs and utilization to meaningful business transactions and "right-size" supply with demand at the functional level.

If we take the technology, vendor and project names out of the picture and focus on capabilities we can describe this ecosystem in terms of enablers. Once we define these enablers and their roles in each of the three layers above we see pretty clearly that concepts like policy, orchestration etc. actually occur in several places and can draw the following parallels...

1) A baggage handler in New York has no need to know what a baggage handler in Atlanta is doing. Each does need to coordinate with their respective (and local) air traffic controller.
2) Air traffic control in Atlanta does need to be aware of what the ATC in New York is doing.
3) The blender Alexis uses to make us coctails does not care if the power it uses came from Georgia Power, Alabama Power or Florida power, nor does it care if it was generated using Coal, Hydro, Nuclear etc. power...
4) Georgia power does not sit in design meetings with the Xbox engineering team.
5) The system to generate power, handle luggage, load meals on planes etc. is free to innovate and be adopted independently from the ability to fly people around reliably.

My hopes for the CNCF reference model is that we show this reference model inclusive of the OCF and DAB and independent of the technologies, projects and products which can be used to enable the behaviors. I also hope that ongoing we maintain the list of these players and where they play when they implement according to the reference architecture.

Thoughts? Have I completely lost my mind?

I think this goes back to what is the charter of the CNCF.


Taking a few short cuts in this narrative and avoiding some of the politics.
Containers became mainstream when docker "standardized" their use. The
industry saw this rapid adoption and suggested a forum should "govern" these
standards which resulted in the OCP->OCI. From the OCI charter,
"...industry participants may easily contribute to building a
vendor-neutral, portable and open specification and runtime...". So we have
both a spec and working code.


What was missing, was the equivalent for container management (orchestrator,
control plane, monitoring) solutions. I believe this was the genesis of the
CNCF, originated by Craig and why k8s was the initial project. The original
reference architecture provided a simple view of these functional
components. BTW, most would see the similarities between this and OpenStack
for VMs. I personally have no interest in seeing the CNCF focused on one
implementation.


Assuming I'm not completely off the path, the target audience for the ref
arch is anyone assembling a container management solution (orchestrator,
control plane etc.) and anyone attempting to build a functional component
that would fit within that architecture. Pretty much every company I've
spoken with is currently rolling their own from a select set of open source
projects and developing their own glue to fill gaps and stitch the pieces

Hi all,

Yesterday we had our 2nd discussion about the 'marketecture' stack that Ken
and I put out. One piece of feedback, from Doug Davis by email, and then eg
from Alan Conley on the call, was that much more detail could help.

I believe this is a "target audience" issue. We may need different material

example - I argued that for developer end users, less detail is good.

It would be very helpful to hear from the people advocating for more detail,
