EC2 Update – T2.Nano Instances Now Available
- sagargv 11y agoHow does Amazon implement instances like t2.nano? If there are 40 t2.nano instances on a quad core physical machine, what happens when all the users want 100% CPU, even if it's only for 10 minutes? Are instances automatically migrated to a different physical machine if this happens?
- supersan 11y agoI've tweeted to you twice and asked your customer support about this too but I have never gotten a reply to it. So I'm asking you here.. When are you gonna allow reserved instances for Indian customers? Right now I cannot purchase reserved instances and so my bills are much much more than what others are paying. P.S. Here is the screenshot when I try to purchase. There has been no update for 1 year now. http://i.imgur.com/oZAHMt5.jpg http://i.imgur.com/oZAHMt5.jpg
- Zombieball 11y agoIn all honesty I don't think it's in Jeff Barr's authority to release roadmap plans or definitive answers to questions like this. My experience in the past has been he has always been helpful in connecting you to individuals who may be able to answer these sorts of questions. So I suppose it doesn't hurt to ask. Just don't get your hopes up :)
- supersan 11y agoWhom should I contact then? Their customer support just replies with a canned reply :(
- msravi 11y agoHuh? How is it that I'm able to buy reserved instances? I'm in India and I've bought reserved instances. It's been a pretty bad decision to buy (https://news.ycombinator.com/item?id=10741966 https://news.ycombinator.com/item?id=10741966), but I can. I can't sell them though, so I'm stuck.
- supersan 11y agoI'm not sure. See, the screenshot above. The confusion about this is the most difficult part of it and Amazon support just replies with a canned reply. That is why I was hoping someone like jeffbarr could shed some light on this.. Looks nice it was just another vain attempt to get an answer from them :(
- siscia 11y agoSince we are talking about cloud provider, any experience with https://www.scaleway.com/ https://www.scaleway.com/ ? Their price is so much cheaper and give to you bare metal ARM, but I can count on them ?
- amock 11y agoI've been running a server for a few months without any issues. The CPU is really slow, but the network seems ok.
- siscia 11y agoNice, what you mean by "slow" ? Just to have an idea, what is your workload ? Serving and rendering html ?
- amock 11y agoI used one server as a Tor relay and another to server static files. The Tor node used almost 100% of one core to server about 25mbps of traffic and there wasn't enough load on the static file server to notice the CPU load, but decompressing an xz file took many times as long as an x86 VPS I had.
- sagargv 11y agoThey seem to have run out of ips/servers and aren't accepting new users. So, I wouldn't host anything serious with them just yet.
- Aissen 11y agoBeen using them for a while, it's great. I'm running a non-mining bitcoin client (basically just sync-ing the blockchain), it runs well. Honestly a better proposal than Amazon's IMHO.
- nodesocket 11y agoVery nice. A direct competitor to the entry level DigitalOcean 512MB servers which cost $5 a month. The great thing is that as your grow, you won't outgrow AWS, which is not necessary true with DO.
- brianwawok 11y agoIs it? You can peg the DO cpu. You can only use 5% of the cpu here. I think this is cool don't get me wrong. Lots of uses for a cheap low use server. But this is pretty niche.
- yid 11y agoFrom TFA: > The t2.nano offers the full performance of a high frequency Intel CPU core if your workload utilizes less than 5% of the core on average over 24 hours. This means you get the full CPU if you have a bursty workload, and really is no different from what DO's policy is: > We do not set a cap on CPU usage by default but we do monitor for droplets doing a consistent 100% CPU and may CPU limit droplets displaying this behavior. In the EC2 case, the CPU throttling policy is just explicit.

- kbuck 11y agoHaving been hit by AWS's CPU cap before (on the t2.micro instance type) and having used many other providers, I can tell you firsthand that AWS's CPU limits are MUCH lower than their competitors'. In our case, a sustained usage of about 15% CPU caused our VM to eventually be starved of CPU time, which in turn crashed the software running on it. I've never dealt with stricter CPU limits than AWS's. Most providers will not be happy if you peg an entire core to 100% (after all, the physical cores are oversold), but they usually don't mind if the percentage is even as big as 50%.
- jsmthrowaway 11y agoYou've outgrown the micro. The strict CPU accounting doesn't exist beyond the micro and the nano. I regularly pegged every core offered on 4xls and what not and never heard a peep from Amazon over several years. My point is this is an instance type thing, not a provider thing as you've extrapolated. They're experimenting with vast overselling on those instance types and it's not across the board.

- matt4077 11y agoThis would be excellent if you could accrue more than the 72 minutes worth' of CPU credits. At least my use case is 'low traffic, with the occasional link from a high-traffic site'. These happen every few months, not every three days. But they also last 36 hours or so, not 72 minutes. Total CPU usage is similar, but it's distributed differently.
- cperciva 11y agoThere's a trade-off between how much they allow you to spike and how long they allow you to spike for. They could have 20 t2.nano instances packed onto one CPU; the longer you can spike for, the more likely it is that another instance is going to end up spiking at the same time as you. I'm sure Amazon has looked at the CPU-usage behaviour of millions of EC2 instances -- quite likely across hundreds of billions of data points -- and picked this as a reasonable tradeoff. For your use case, I think autoscaling is probably the answer. Keep one t2.nano running continuously but tell EC2 to spin up a new t2.large if you get a burst of traffic.
- matt4077 11y agoYeah, they obviously put more thought into this than I ever will. Although they offer instances with 40 (v)CPUs so I'd assume they could technically run 800 nanos on one of those and efficiently deal with such spikes? Either way, I suspect their reasoning is more economical than technical, in that they know full well that I can afford more than 5$/mo. (which I'm taking to linode for now, but oy vey, AWS, we'll always have Paris)
- cperciva 11y agoRight, these are presumably running on boxes with many CPUs each. Whether instances migrate, I don't know; due to NUMA concerns they might be pinning instances to cores. The other issue to consider is correlated spikes: When you aggregate 800 instances, you're probably going to see a pretty clear diurnal cycle. (And quite possibly middle-of-the-night spikes as synchronized cron jobs all kick off, too.)

- yeukhon 11y agoFor my use case, t2.nano would be great but I need better network throughput.
- imperialdrive 11y agowow, I must be doing something wrong... I have a single c4.4xlarge running a single wordpress site at max 200 active users and still running into cpu bottleneck... 1K+/mo sheesh.... I use t2.medium for DC's for 5 users and 5 servers lol... please let me know what a nano is good for? not to mention, I need multiple 10+TB volumes, and magnetic only go to 1TB, so I need to span, and spanning breaks after 4+ drives, so now I'm at SSD, and that's costing me 1K/mo for each copy and I need many, sigh i miss buying my own supermicro systems at ~10k/ea, hosting a full rack at at a colo for 1k/mo and then just setup correctly and check-in once a month now, amazon is getting 15k/mo from me, but i must say, my back thanks them for 0lbs of equipment to lift, so probably worth it for a hernia surgery.
- nullspace 11y agoWoah, c4.4xlarge does sound heavy for 200 users!
- keehun 11y agoDo you cache at all?
- imperialdrive 11y agoi think my main issue is thread-safe vs non-thread-safe php and the issues it has with IIS
- tszming 11y agoAlways add $49/month (the basic support plan) if you want to compare AWS with DO/Linode, don't just look at the $5/month instance charge.
- ranman 11y ago? meaning DO/Linode support for a $5/month customer is good? I've not had positive experiences with either... but then again my experiences with AWS (non-business) support haven't been so positive either.
- tszming 11y agoGood or bad is very subjective, but in AWS without a support plan, there is no way to contact them except you create a thread in a public forum asking for help. If you are lucky your post is not being ignored then someone will reply you maybe within one day (then back and forth might cost you one or two days to get issue resolved luckily). In DO/Linode you can create a support ticket to them and usually they respond within a few minutes, this is a huge difference.
- nickjj 11y agoI've had pretty good support on DO's $10/month plan and I imagine their $5/month plan would be the same. 1-5 hour turn around times on initial responses and I've gotten them to enable things like the recovery partition due to an instance running out of disk space. Sometimes it takes a few responses to get a resolution but at that price point I can't really complain because they've even helped resolve issues that were my fault.

- 7ewis 11y agoLooks like the t2.nano isn't included as part of the Free Tier, seems a bit strange?
