It's more than that - it's all the latency that you can remove from the equation with your bare-metal server. No network latency between nodes, less memory ban

It's more than that - it's all the latency that you can remove from the equation with your bare-metal server.
No network latency between nodes, less memory bandwidth latency/contention as there is in VMs, no caching architecture latency needed when you can just tell e.g. Postgres to use gigs of RAM and then let Linux's disk caching take care of the rest (and not need a separate caching architecture).
- matt-p 1y agoThe difference between a fairly expensive ($300) RDS instance + EC2 in the same region vs a $90 dedicated server with a NVME drive and postgres in a container is absolutely insane.
- bspammer 1y agoA fair comparison would include the cost of the DBA who will be responsible for backups, updates, monitoring, security and access control. That’s what RDS is actually competing with.
- matt-p 1y agoTotally. My frustration isn't even price though RDS is literally just dog slow.
- shrubble 1y agoPaying someone $2000 to set that up once should result in the costs being recovered in what, 18 months? If you’re running Postgres locally you can turn off the TCP/IP part; nothing more to audit there. SSH based copying of backups to a remote server is simple. If not accessible via network, you can stay on whatever version of Postgres you want. I’ve heard these arguments since AWS launched, and all that time I’ve been running Postgres (since 2004 actually) and have never encountered all these phantom issues that are claimed as being expensive or extremely difficult.
- applied_heat 1y ago$2k? That’s a $100k project for a medium size Corp
- sysguest 1y agohmm where did you get the numbers? (what's "medium-size corp" and how did you come up with $100k ?)
- Aeolun 1y agoI’m assuming he’s talking about the corporate team of DBA’s that will spend weeks discussing the best way to copy a bunch of SQL files to S3
- christophilus 1y ago$200 does seem too low. $100k seems waaay too high. That sounds like an AWS talking point.
- sahilagarwal 1y agoI guess my non-management / non-business side is show here, but how can it be that much?? I still remember I designed a fairly simple cron job that took database backups when I was a junior developer. It gets even easier now that you have cheap s3 - just upload the dump to s3 every day and set the s3 deletion policy to whatever is feasible for you.
- fragmede 1y agoHow much were you paid as a jr developer, and how long did it take you to set up? Then round up to mid-level developer, and add in hardware and software costs.
- dijit 1y agoThat's a deflection. The question isn't about a developer's salary; it's about the fundamental difference between a one-time investment and a permanent cost. Either way: 1 day of a mid-level developer in the majority of the world (basically: anywhere except Zurich, NYC or SF) is between €208 and €291. (Yearly salary of €50-€70k) A junior developer's time for setup and the cost of hardware is practically a one-off expense. It's a few days of work at most. The alternative you're advocating for (a recurring SaaS fee) is a permanent rent trap. That money is gone forever, with no asset or investment to show for it. Over a few years, you'll have spent tens of thousands of dollars for nothing. The real cost is not what you pay a developer; it's what you lose by never owning your tools.
- yjftsjthsd-h 1y agoAs long as you also include the Cloud Certified DevOps Engineer™[0] to set up that RDS instance. [0] A normal sysadmin remains vaguely bemused at their job title and the way it changes every couple years.
- mrweasel 1y agoIt's also interesting that the cloud engineer can apparently be both a DBA, network-, storage- and backup engineer, but if you move the same services on-prem, you apparently need specialists for each task. Sometimes even the certified cloud engineers can't tell you why an RDS behaves the way it does, nor can they really fix it. Sometimes you really do need a DBA, but that applies equally to on-prem and cloud. I'm a sysadmin, but have been labelled and sold as: Consultant (sounds expensive), DevOps engineer, Cloud Engineer, Operations Expert and right now a Site Reliability Engineer.... I'm a systems administrator.
- Aeolun 1y agoIf you’ve started working in the industry more than about 15 years ago all the titles sound quaint.
- data_marsupial 1y agoNeed to get Platform Engineer for a full house
- icedchai 1y agoI haven't seen a company that hired DBAs in over 15 years. I think the "DevOps" movement sent them packing, along with SysAdmins.
- vidarh 1y agoI do consulting in this space, and we consistently make more money from people who insist on using cloud services, because their setups tend to need far more work.
- sgarland 1y agoYou don’t need a DBA for any of those, you need someone who can read some docs. It’s not witchcraft.
- Aeolun 1y agoI’d argue that AWS is witchcraft a lot of the time. They’ll have all these they claim will work for everything, but you’ll always find one of the things you’d expect to be unavailable.
- lelanthran 1y agoThe RDS solution doesn't need a technical person to set it up? It doesn't need someone who knows how to use the labrythine AWS services and console?
- whstl 1y agoAgree. These comments sound super absurd to me, because RDS is difficult as hell to setup, unless you do it very frequently or already have it in IoC format, since one needs setting up a VPC, subnets, security groups, internet gateway, etc. It's not like creating a DynamoDB, Lambda or S3 where a non-technical person can learn it in a few hours. Sure, one might find some random Terraform file online to do this or vibe-code some CloudFormation, but that's not really a fair comparison.
- Cthulhu_ 1y agoWhile that's fair, most organizations I've worked at in the past decade have had a dedicated team for managing their cloud setup, which is also responsible for backups, updates, monitoring, security and access control. I don't think they're competing.
- benterix 1y agoYou are aware that RDS needs backups, setting up monitoring properly, defining access, providing secrets management etc., and updates between major versions are not automatic? RDS has a value. But for many teams the price paid for this value is ridiculously high when compared to other options.
- pdhborges 1y agoAWS can make major version upgrades automatically now with less downtime. I think they do the logical replication dance internally.
- steveBK123 1y agoMy firm paid DBAs for RDS as well so..
- zenmac 1y agoYeah but AWS SRE are what making the big bucks! Soooo what can you do? It is nice to see many people here on HN are supporting open network and platform and making very drastic comments as to encouraging google engineers to quite their jobs. I totally also understand why some people with family to support mortgage to pay they can't just walk way from a job at FAANG or MAMAA type place. Looking at your comparison, this point it just seems like a scam.
- jpgvm 1y agoRight now the big bucks are in managing massive bare metal GPU clusters.
- reactordev 1y agoThis. Clustering and managing Nvidia at scale is the new hotness demanding half-million dollar salaries.

- benterix 1y agoYeah, let's use the opportunity while it lasts.
