one of the frustrating things about public IaaS like AWS and evergreen SaaS (even on-prem) like @pivotalcf is that you can't constrain the 'version' of the dependency. that is, AWS is going to evolve and it MIGHT break assumptions into your code from yesteryear. 1/N

This is fine when there's a robust CI/CD practice to continuously (daily, at worst?) confirm that things haven't broken and an on-call team able to respond to such changes. It gets complicated when you want to ramp down the team and reprioritize their efforts 2/N

The result is that organizations can't completely wash their hands of software anymore. Obviously, a mature discussion of operational responsibilities in 2018 includes ongoing security maintenance, and so I'm fine with the idea that there's a long tail for maintenance. 3/N

This long-long tail for maintenance - puts into sharp relief an important idea: you need to minimize your support burden. 4/N

one aspect of this is goal is don't run that which you can't charge for. If you're using cloud but ALSO running / maintaining @elastic yourself (when you could pay them) or @confluentinc (when you could pay them to do it), etc., then you're doing it wrong. 5/N

another aspect of this goal is that you should build on the simplest primitives you can today because in the long term all things blur together and become inscrutable and somebody, some day, is going to get a 5am phone call to revive a mysteriously dead service in the future 6/N

So, want to deploy an app and a database? that's 3 very short commands using the @CloudFoundry `cf` CLI in 2018. If you want to do that using AWS, you're going to need to setup a load balancer, web server, database, API gateway, IAM roles/users, backup, and monitoring. How? 7/N

Glad you asked! You could drag-and-drool on the console, you can use the `aws` CLI or you could use Cloud Formation, in both `.json` and `.yaml` formats. And, from 2016, you can also use SAM for Lambda workloads. 8/N

There is no such thing as a statically linked cloud platform dependency. Build and operate accordingly.
