Ansible, Nornir, and other automation frameworks are excellent for generating and deploying configurations in an automated fashion. In Ansible, you can run a playbook, loop through hosts in your inventory file, and deploy configurations with host-specific information by leveraging host_vars and group_vars. Unfortunately, as your automation environment starts to grow and become more critical, you’ll […]

When you’re looking at moving to a new technology, whether it be SD-WAN or cloud, you’re going to be told all about the capabilities it has and all the shiny new stuff it can do for you. I would almost guarantee that you’re going to hear the words “agile” and “flexible” at some point during the conversation. Now, obviously those two things are different based on the fact there are two different words to describe what they do. But I’ve also heard people use them interchangeably. What does it mean to be agile? And is it better to be flexible too?
Agility is the ability to move quickly and easily. It’s a quality displayed by athletes and fighters the world over. It’s a combination of reflexes and skill. Agility gives you the ability to react quickly to situations.
What does that mean in a technology sense? Mostly, agile solutions or methodologies are able to react to changing conditions or requirements quickly and adapt to meet those needs. Imagine a platform that can react to the changing needs of users. Or add new functions on the fly on demand. That’s the kind of agility that comes from software functionality Continue reading

After introducing the fallacies of distributed computing in the How Networks Really Work webinar, I focused on the first one: the network is (not) reliable.
While that might be understood by most networking professionals (and ignored by many developers), here’s an interesting shocker: even TCP is not always reliable (see also: Joel Spolsky’s take on Leaky Abstractions).
Cloudburst: stateful functions-as-a-service, Sreekanti et al., arXiv 2020
Today’s paper choice is a fresh-from-the-arXivs take on serverless computing from the RISELab at Berkeley, addressing some of the limitations outlined in last year’s ‘Berkeley view on serverless computing.’ Stateless is fine until you need state, at which point the coarse-grained solutions offered by current platforms limit the kinds of application designs that work well. Last week we looked at a function shipping solution to the problem; Cloudburst uses the more common data shipping to bring data to caches next to function runtimes (though you could also make a case that the scheduling algorithm placing function execution in locations where the data is cached a flavour of function-shipping too).
Given the simplicity and economic appeal of FaaS, it is interesting to explore designs that preserve the autoscaling and operational benefits of current offerings, while adding performant, cost-efficient and consistent shared state and communication.
The key ingredients of Cloudburst are a highly-scalable key-value store for persistent state (Anna), local caches co-located with function execution environments, and cache-consistency protocols to preserve developer sanity while data is moved in and out of those caches. Oh, and there’s a scheduler Continue reading
Prior to my current job, I enjoyed the time I invested in the community. I spent quite a bit of time on The Cisco Learning Network helping those that were early in career. I also blogged here regularly (typically weekly) and spent time in the Twitterverse and on Slack. From this perspective, taking a job with a vendor was more different than I expected. It was like someone flipped a switch and I was completely spent at the end of each and every day.
On a few occasions, I have tried to get back what I would have previously considered some level of normalcy with regards to the community. I have decided that this year is my year to make some major changes. I must do a better job prioritizing things I care about and realize that some [read many] things just aren’t going to get done. That is one thing I’ve learned over the past few years. Even though I have always felt that my workload was significant, there is nothing like having a job in which you can only get a small portion of the overall work completed. It just doesn’t feel good.
The community and the relationships Continue reading
