One day you will do containers.
If you want to know how k8n (Kubernetes) can help you with Docker containers, then read [WayBack] The Illustrated Guide to Kubernetes – The Isoblog. and watch the video below.
Very well explained!

Via [WayBack] Limits on Everything – The Isoblog.:
A posting at Brave New Geek about limits on everything, for example limits on message sizes and numbers of in-flight messages in message queues. Interesting read.
Very interesting read indeed: [WayBack] Take It to the Limit: Considerations for Building Reliable Systems – Brave New Geek
You have to set limits, which begs for a few questions:
Food for thought…
The first can be done with benchmarking, see for instance these from the same blogs above:
Enforcing limits depends in your infrastructure and your communication stacks.

Abstract from this morning’s Twitter feed:
1.1.1.1 [Wayback] DNS is broken in many areas (because of for instance AT&T, Vodafone, Cisco screwing up and 1.1.1.1 historically being marked for research purposes)9.9.9.9 [Wayback] DNS has government affiliation (owned by Quad9, but the partner list below does not look nice)So what’s left?
1.0.0.1 alternative to 1.1.1.1
8.8.8.8 with secondary at 8.8.4.4
There are a more interesting IPv4 addresses untaken for DNS, but I’m not sure they are likable enough:

From [WayBack] Docker – Docker Cloud Migration Notification and FAQs:
The services on Docker Cloud that provide application, node, and swarm cluster management will be shutting down on May 21.
…
If you do not migrate by May 21, your applications running on the Docker node cluster management service will cease to operate.
Swarms will continue to function; however, if you do not retrieve your SSH keys for the Swarms being managed by our swarm cluster management service, you will be unable to access your swarms using your Docker ID. For instructions on how to retrieve and access your Swarms with SSH keys, please refer to the Docker docs.
So soon, no more [WayBack] Docker Cloud – Build, Ship and Run any App, Anywhere.
Remember: still the cloud is other peoples computers, so be sure you can move when needed.

Over time, there are lots of complaints about Embarcadero related internet services (like forums, QC, Appanalytics, docwiki, blogs, web site, maintenance, …) so to track uptime, I’ve created a set of EmbarcaderoMonitoring pages:
This is preliminary work based on my own lists of Embarcadero endpoints combined with some research like [WayBack] dnsdumpster embarcadero.com.png and [WayBack] IdentIPSpy
Underneath, they run on the uptimerobot.com infrastructure which has a limit of 50 free monitors.
It means I have to:
Any ideas on improving this are welcome: please post a comment here on on the resulting G+ thread.
Note it likely won’t show cases like when the website was hacked or TLS certificate issues like in SSLLabs security reports for some embarcadero subdomains. I need to think about a means for those, as it will certainly help monitoring my own infrastructure in a similar way.

An important question for many people, so if you want to know more or get started: [WayBack] Scott Hanselman on Twitter: “Why should I care about Kubernetes, Docker, and Container Orchestration?” followed by:
Yes, AKS is Azure Container Services (go figure!).

[WayBack] What happens when a huge number of people share a single grocery store loyalty card? – The Old New Thing
An interesting discussion in the comments besides this interesting article observation:
What messes up their data analysis is when two people with different lifestyles swap cards. The system sees that somebody who used to buy yogurt and bulk brewer’s yeast is now buying potato chips and frozen pizzas, and it can’t figure out what is going on.

This is what DevOps is all about: [WayBack] jessie frazelle on Twitter: “Hire the people who will automate themselves out of a job, then just keep giving them jobs.”
I had seen the tweet before, but forgot to save it. Jonas Bandi reminded me of it at [WayBack] Weekend Reader: End of Year Edition – reality-loop.
Jessie is doing great work. For instance, she developed and published contained.af, and nobody captured the flag yet: [WayBack] jessie frazelle on Twitter: «A year ago I made contained.af and it’s launched over 128,000 containers & no one has retrieved the flag».
The game runs in a container, gives you console access and has a bunch of questions. Still need to dig deeper in it, as it is a fascinating set-up. If you like to try it:
Wishing you a year where nobody captures your flags (:
