Orange Matter: Automation Paralysis
I’ve been blogging for Solarwinds recently, posting on Orange Matter, with a cross-post to the Thwack Geek Speak forum. This post examines how it’s easy to get so focused on automating the small stuff we have difficulty turning that into the more cohesive automation solution that we’d like to have.
This post appeared on Orange Matter as “Automation Paralysis: Why We Get Stuck Automating The Small Stuff“, but I’m also linking to the version posted on Thwack, mainly because that format allowed me to use more images and be slightly more irreverent. Irreverent? Moi? Of course.
I’d love it if you were to take a moment to visit and read, and maybe even comment!

Get IoT Smart: Homework for Many Indonesians
Today’s guest post is from Bhredipta Socarana, an Intellectual Property lawyer based in Indonesia and a Youth@IGF Fellow.
As one of the most populated countries, Indonesia has grown as one of the biggest markets for technology development. From the import of various over-the-top platforms to the implementation of Artificial Intelligence, technology has changed the Indonesian livelihood, including my own. This is also the case for Internet of Things (IoT).
As an emerging country, Indonesia admittedly has not been an advance player in responding to technology improvement. Despite the heavy invasion of technology-related products, many Indonesians have homework to do, especially for IoT. The business player needs to be aware of the responsibility of manufacturing and distributing IoT, while the public must also be aware of the various risks that they may be exposed to using IoT products.
Through the rapid development of technology and the intention of the Indonesian government to push the public to enter the “Industrial Revolution 4.0,” it will be mostly impossible to prevent penetration of IoT to our life. This leaves the public with the need to get smart with IoT.
Privacy and cybersecurity are among the issues revolving around IoT, and the need to have a Continue reading
CLOS Topology
Edson Erwin invented this highly scalable and optimized way of connecting network nodes in the 1930s and Charles Clos made the telephone nodes interconnection design using that solution. It was even before we had IP networks. He invented it in order to optimize the architecture of telephony network systems back then. It was not used in IP based network for last few decades but it experienced a big comeback with new datacenter design in the last few years. It was first invented only for scalability requirements that it solved beautifully. In new datacenter design, CLOS topology of interconnecting network devices scalability

Firewall Ruleset Automation with CI Pipeline
One of my readers sent me a description of their automation system that manages firewall rulesets on Fortigate firewalls using NAPALM to manage device configurations.
In his own words:
We are now managing thousands of address objects, services and firewall policies using David Barroso’s FortiOS Napalm module. This works very well and with a few caveats (such as finding a way to enforce the ordering of firewall policies) we are able to manage all the configuration of our firewalls from a single Ansible playbook.
The did the right thing and implemented an abstracted data model using GitOps to manage it:

The time has come for IT to once again dive into the world of homegrown automation for running their networks.
Network teams have a love/hate relationship with
Time after time, though, something goes wrong with the cobbled together systems. Soon, rolling back and correcting mistakes or nursing along the automation as platforms and environments evolve takes more time and effort
Now, the confluence of several trends in IT has made it clear that it is automation time again. First and foremost, the focus on digital Continue reading
Blending into software infrastructure
Electronic networks existed long before electronic compute and storage. Early on, the network was simple wires and switch boards, and the endpoints were humans. Telegraphs transcoded taps into on/off voltage on the wire and back to audible clicks. Telephones transcoded voice into amplitude modulated voltage and back to voice.
Since then, the network has existed as a unique entity apart from the things it connected. Until now.
Less than two decades ago most applications were built in vertical silos. Each application got its own servers, storage, database and so on. The only thing applications shared was the network. The network was the closest thing to a shared resource pool — the original “cloud”. With increasing digital transformation, other services were also pooled, such as storage and database. However each application interfaced with these pooled resources and with other applications directly. Applications had little in common other than Continue reading

Upgrading Cloud Infrastructure Made Easier and Safer Using Cloudflare Workers and Workers KV
This is a guest post by Ben Chartrand, who is a Development Manager at Timely. You can check out some of Ben's other Workers projects on his GitHub and his blog.
At Timely we started a project to migrate our web applications from legacy Azure services to a modern PaaS offering. In theory it meant no code changes.
We decided to start with our webhooks. All our endpoints can be grouped into four categories:
- Integration with internal tools i.e. HelpScout, monitoring endpoint for PagerDuty
- Payment confirmations
- Calendar integrations i.e. Google Calendar
- SMS confirmations
Despite their limited number, these are vitally important. We did a lot of testing but it was clear we’d only really know if everything was working once we had production traffic. How could we migrate traffic?
Option 1
Change the CNAME to point to the new hosting infrastructure. This is high risk. DNS takes time to propagate so, if we needed to roll back, it would take time. We would also be shifting over everything at once.
Option 2
Use a traffic manager to shift a percentage of traffic using Cloudflare Load Balancing. We could start at, say, 5% traffic to the new infrastructure Continue reading
