Chicken or Egg: Abstraction and Automation

But will abstraction necessarily lead to automation?

For many SDN and DevOps enthusiasts, the natural outcome of this wave of technological change is a highly-automated network that is well-orchestrated with surrounding systems and applications. One of the prevailing thoughts is that this level of automation is a well-formed abstraction layer. With the abstractions in place, the army of network engineers will be unencumbered by device configuration, and automation will ensure.

Or will it?

First off, let me say that abstraction is absolutely necessary. There is no doubt that networking will only advance if we can both remove unnecessary elements and simplify those that remain. We have to accomplish this in a way that is vendor (and ideally technology) agnostic. Abstraction is clearly the path forward.

But will abstraction necessarily lead to automation?
For the vast majority of network engineers who are designing and actively managing networks today, automation means writing shell or Perl scripts. The scripts themselves qualify as automation insofar as they remove keystrokes, but they basically execute the same serial logic that has dominated networking devices for decades.

When you want to make a switch or a router do something, you specify some configuration. Then you specify some other configuration. And again and again until you get through the litany of parameters that collectively make the device work. This workflow is so ingrained in our collective psyche that we inherently serialize the tasks required to make the network work.

There have actually been companies that have done a decent job of breaking the habit of serialized configuration. Juniper’s flagship operating system Junos moved to a more code-like representation of configuration, making no assumptions about the ordering of specific tasks. But our training runs deep, and even the Juniper guys will tell you that the biggest barrier to entry is familiarity with the UI.

We are addicted to our serialized behavior.
One of the side effects of highly-serialized configuration is that we tend to think extremely linearly and transactionally. There are a lot of network engineers for whom any kind of object-oriented approach is almost too foreign to really embrace. So when they try to automate tasks, they fall back into a sequencing of steps, repeated as many times as necessary. Automation without reuse is painfully difficult to propagate beyond only the most repetitive tasks.

And so we end up in a scenario where automation is basically synonymous with scripting, and where the value is largely applied only to the most frequently-executed tasks.

Where could automation take us?
If we think through where automation could take us, we ideally aim a little higher. Automation could mean the automated exchange of data between collaborative systems in support of some task. For instance, you might want your servers to communicate to your network so that when a new application is spun up (or a VM moves), you get corresponding policy changes, firewall or load balancer changes, and potentially network capacity allocation.

For most network engineers, the idea that infrastructure communicates and dynamically provides a service is science fiction. Our serialized mode of operation simply doesn’t support this kind of multilateral communication. Even if the abstractions remove some of the configuration complexity, the mental block is around sequencing.

If the current networking model has taught us anything, it should be that our network engineers are quite capable of managing tons of inputs and outputs. Now, whether that ought to be a requirement for the job is another question entirely. But as a group, network engineers are certainly capable of handling a lot of variables. That abstraction reduces these variables to the most meaningful is very interesting, but it wouldn’t seem that input management is the biggest bottleneck to automation.

The barrier to automation

Rather, the biggest barrier to automation is that workflow is so structured. First, it was the devices themselves that forced the structure. Then it was the processes (ITIL anyone?) that forced it. The end result is that we have built a discipline so dependent on structure that it actually impedes our own progress.

If we want to get to automation, we need to find a way to work around—or perhaps work within—this structure.

What we are really talking about is changing how we think about provisioning and managing a network. Why do you think there is so much angst when people talk about network engineers needing to learn to code? It’s because moving from a serialized set of steps to an object-oriented way of thinking about the problem is extremely difficult.

People aren’t pushing back because learning a new language is hard. Or at least they shouldn’t be. Look at any networking device configuration and tell me that you aren’t already a master coder. The biggest difference is that you you are using an interpreted language called Cisco CLI (or Junos CLI or whatever CLI).

What next?
What we need to do is bite off small (dare I say tiny) workflow elements, automate those, and then string them together into larger workflows. This implies a couple of things. First, we need to think less about discrete capabilities and more about how they exist within some broader workflow context. Second, we need to understand how these building blocks fit together. It’s the connecting of individual workflows that forms the basis for automation, and those connections highlight the pieces of information that flow across workflow boundaries.

More bluntly, the data that stitches together workflows ends up being the stuff that needs to be in an abstraction. It very well could be that getting the automation parts right will help us get to better abstractions.

Obviously we have to work the process from both ends – abstraction down, and workflow up. I don’t think it’s as simple as one or the other, which is why abstraction and automation might be a networking incarnation of the age-old chicken-and-egg question.

Any startup has to have a clear go –to-market strategy from the beginning. Similarly, any data science project has to have a go to production strategy from its first days, so it could go beyond proof-of-concept. Machine learning and artificial intelligence in production would result in hundreds of training pipelines and machine learning models that are continuously revised by teams of data scientists and seamlessly connected with web applications for tenants and users.
