Whiteboard Confessional: Route 53 DB
Join me as I launch a new series called Whiteboard Confessional that explores how whiteboard architecture diagrams might look pretty but rarely work as designed in production. To kick off the series, we’re taking a look at everyone’s favorite database, AWS Route 53, while touching upon a number of topics, including what data centers used to look like, the emergence of virtualization and the impact it had, configuration management databases and how they differ from configuration management tools like Chef and Puppet, why using DNS as a configuration management database is inherently an awful idea, how there’s almost always a better solution than whatever you built in your own isolated environment, how just because someone built something doesn’t mean they knew what they were doing, and more.

Networking in the Cloud Fundamentals: BGP Revisited with Ivan Pepelnjak
Join me as I conclude my series on cloud fundamentals by reexamining border gateway protocol (BGP) with Ivan Pepelnjak, Chief Technology Advisor at NIL Data Communications. This episode features a discussion about what Ivan believes Corey got wrong about BGP in a previous episode of this podcast; Ivan’s telling of the history of BGP and how it has evolved over time; why Ivan thinks that, when something goes wrong, it’s not fair to blame the tool itself, and that the misuse of the tool is what deserves the blame; why regulators may have to think about driver’s licenses for the internet; the year modern BGP emerged; and more.

Networking in the Cloud Fundamentals: Cloud and the Last Mile
Join me as continue my series on cloud fundamentals by examining the last mile of the cloud, including how exciting it was to move away from Comcast, how a distribution of Linux with a potentially offensive name solved my home connectivity issues, why I chose to use a region I never otherwise use when setting up my home network, the real reason why latency affects applications (hint: it’s not latency from a DNS server or latency that stems from geographical distances), the party that’s really responsible for network performance, and more.

Networking in the Cloud Fundamentals: Connectivity Issues in EC2
Join me as continue my series on cloud fundamentals with a look at connectivity issues in EC2, including how to troubleshoot said issues, why DNS is often the cause of connectivity issues and how to get around that, security groups and why they’re fascinating, how IPv6 might be the cause of connectivity issues in certain instances, VPC considerations to keep in mind when troubleshooting issues, when you should try to replicate your issue by spinning up a new server and when you absolutely shouldn’t, why connectivity issues should be resolved relatively quickly in the cloud era, what I believe the most transformative feature of the cloud is, and more.
