I hope this won’t be counted as some form of self-promotion, even though I am sharing a post from my own blog.
As a tech worker who works in a Cloud shop, I wanted to elaborate the many reasons why I find working with Clouds terrible, from multiple points of view.
I tried to organize my thoughts in a (relatively long) post, in which both technical aspects and political aspects (which are very related) are covered.
I am sure many people will have different perspectives, and this could be potentially also a nice prompt for a discussion.
Why not outsourcing just the hardware then? Dedicated servers and Kubernetes slapped on them. Hardware failure mitigated for the most part, and the full effort goes into making the cluster as resilient as possible, for 1/5 of the cost of AWS. If machines burn, it’s not your problem (you can have them spread over multiple sites, DCs, rooms, racks) anymore.
We did that (with Rackspace) for years before migrating to AWS. AWS is still far better from a service & flexibility perspective.
My employers website has certain times of the year where we see a huge increase in web traffic. When we had a hosted solution it took weeks of preparation to provision additional web servers to handle that load. We had to submit formal requests for additional servers, document how to wire them into our network & required firewall rules, etc. Then we had to wait an arbitrary number of days for them to do the work. And then we had to repeat that whole process when we no longer needed the additional capacity.
With AWS we just define an auto scaling group and additional web servers are spun up automatically when demand is high, and frees them up again when no longer needed. Even if we didn’t use auto scaling we could easily automate this sort of thing via terraform or other tools and spin up additional instances in minutes instead of days.
