Vendor lock-in is an old and well discussed issue. Some people don’t care about it all, jump right in. Others avoid it like a plague. And then there are those who allow it, with some very careful considerations.
I have always been on the side of avoiding vendor lock-in by all costs. But lately, with all the SaaS offerings and cloud providers, I feel like the line becomes a lot more blurred.
Initially, when I started using Amazon AWS, I approached it exclusively as an IaaS, setting up my own servers in such a way that I would be able to move to another vendor in a heartbeat. These days, I’ve grown to trust Amazon a lot more. But I still feel uneasy about some of the lock-in.
To illustrate this point, we have to look no farther than the nine-hundred-pound gorilla of the IAM jungle, which continues to be Microsoft’s ActiveDirectory. I’m not sure I even know what ActiveDirectory is anymore, to be honest. Is it a cloud service? A “hybrid identity” provider? A flippin’ Linux domain controller? The answer to all of those questions appears to be “yes, if that is what you want”, which is why AD implementations will surely keep an army of Microsoft “IT Pros” busy for a couple more decades. Here’s what ActiveDirectory is not: easy to migrate off of.
When put altogether, these bits allow one to have a fast (static content combined with HTTP 2 and top-level networking) and cheap (Jekyll, GitHub, Travis and Let’s Encrypt are free, with the rest of the services costing a few cents here and there) static website, with SSL and HTTP 2.
This is a classic example of how accessible and available is modern technology, if (and only if) you know what you are doing.
