Docker operations slowing down on AWS
And then people consider me a dinosaur when I say, no cloud, just rent a server or two (not colo! just dedicated servers). Your average web service does not need to scale near infinitely; for the same amount of money you pay to Amazon you can overprovision 3-5-10 times and that'll handle your spikes. No surprises. Same amount of work: EC2 and bare metal both gives you a root prompt, go from there. These days you can get things provisioned with 24 hours -- some providers will do it in minutes. Of course, Amazon provides a lot of services beyond basic EC2 instances but if you use them you have a very ugly vendor lock and heaven forbid you want to do something else in the future...This is like a double trap many try to sell to startups: a) you need to scale across many machines and b) the way to scale is the cloud. My take: a single machine (or two for HA) will be enough, if you really want to go big separate the web server from the database but that's it. And yes, I am in the website performance business, I worked on the video purchase platform of one of the largest British television stations and even that didn't require more than a single database server and a single Redis server for caching layer. Harken to https://stackoverflow.com/questions/5131266/increase-postgre... this question from 2011 discussing speeding up from like a thousand inserts per second at the cost of data loss -- today you will write on an SSD and don't need to risk data loss. Does your web site / app really get a thousand writes every second? I thought not. Does it even get a thousand reads? If not, then why are you building a complex database cluster...?The other day I saw quad E7-4870 (yeah won't win any single thread contest but has 40 cores and 80 threads) 512GB RAM servers for $299 a month, with 1TB RAM for $499. Had a low end 2TB SSD for boot and you could add 8x1TB HDD w/ HW RAID for $40...
