It's about damned time. They've been trying to pretend EC2 is for utility computing...like running large distributed apps for a short period of time. But nobody is using it for that...people want Amazon's network and a cheap way to scale from zero to huge for websites. Now that they've finally embraced that, if they'll just resolve the reliability issues, EC2 will be a fantastic hosting option.

Lots of people actually do use EC2 for utility computing, often powered by Hadoop. Most of these folks aren't especially vocal about what they do, but there's data mining on a large scale, drug discovery, and similar stuff happening inside.

davidw3• 18 years ago

I still think they need to resolve the disappearing disk issue, or continue to work on database type things like SimpleDB for persistent storage. Something using an actual relational DB like Postgres would be even better.

It wouldn't surprise me if someone inside Amazon was working on a full relational database appliance as well.

We've been running 24/7 on EC2/S3 for months now with no downtime - 0 bad experiences so far.

ptm• 18 years ago

I too have instances run for 5-6 months without downtime.

The reliabilty concerns are overstated. As long as one accounts for the lack of persistent storage, there should not be a problem.

For me, the biggest step in resolving the reliability issues would be for Amazon to provide load balancing in the API. With a static IP, I could run my own LVS-based load balancer, but I might screw it up. If Amazon provided load balancing, their other customers would help shake out the major bugs, and I'd expect it to work much more reliably.

This is amazing. I am in the process of deploying my webapp, and was considering slicehost due to the static ip's issue.

Then I took another look on the aws pages, and, hooray: elastic ip's were introduced yesterday!

sabat2• 18 years ago

Amazon's pricing compares favorably with slicehost's?

jmtulloss• 18 years ago

Depends on your bandwidth requirements. For somebody without traffic, absolutely not. Slicehost blows them away. That's why I use Slicehost:).

nickb• 18 years ago

Not really. EC2's much more expensive.

trigger• 18 years ago

Great to see this development but won't they need a huge block of IP addresses to support this?

wmf• 18 years ago

So? They'll just pass the cost on to customers.

Great news

Does this mean emails sent from EC2 will not be automatically marked as spam? (right now I think Hotmail marks all EC2 emails as spam). I read that reverse DNS and PTR records are needed to accomplish this. So, this solves just half the problem?

I am asking these as exploratory questions... I don't really have a good grasp on what I am talking about. Please point me to resources.

BTW, do you know of any sample Python code that is used to act on incoming emails in the server?

SwellJoe3• 18 years ago

Amazon probably provides PTR records for all of their IPs. You can check with the host command on Linux:

host 10.1.1.1

You'll also want an SPF record for your zone:

http://www.openspf.org/

DomainKeys are being checked by some webmail providers, but it's only a non-spammy characteristic at this point, not mandatory for delivery. As long as nothing else about your message is stupid (e.g. RFC compliant SMTP server, reasonable DNS records, and you aren't sending 100 per minute to addresses in the same domain), it'll go through.

I'd suggest using whatever Python library will allow you to send using a real SMTP server (or just pipe your email into the mail or sendmail command, which use the local smtpd to send, by default), like Postfix or Sendmail. There may be a standalone library that is actually RFC compliant and handles error conditions properly, but it seems unlikely from a historical standpoint (most such libraries, particularly in the PHP world, are renowned for epic failure). As long as Postfix or Sendmail are configured properly, your mail will be RFC-compliant and will look far less spammy than those coming from a half-assed implementation of the spec.

kirubakaran4• 18 years ago

Great! Thanks.

Can you please point me to some how-to about acting on incoming email using Python? I look far and wide but couldn't find much.

jeremiah2• 18 years ago

Well if you want Python there is pyzor. But the grand-daddy of them all is SpamAssassin, and that is perl. :) FTW!

Perhaps this is just a coincidence, but interesting nevertheless.

This story was submitted to reddit at least two times: the original submission was downmodded to zero (or less), a resubmit eventually to 1. Here, it's at 51 points.

I suppose what I want to say is

127.0.0.1 reddit.com programming.reddit.com

cstejerean• 18 years ago

interesting. OTOH we all know how much reddit sucks and any further comments on the topic are just adding to the noise here.

vegai2• 18 years ago

Old habits die hard. My apologies.

PStamatiou• 18 years ago

so is it much easier to use EC2 as a server now that IPs don't change? IE, you don't need dyndns and/or a load balancer? I wouldn't mind hosting a site of mine on there..

liquidcool• 18 years ago

I was speaking with an Amazon WS evangelist last year and he was recommending a 5 server system: load balancer, two web/app servers and two DB servers.

The issue I brought up was that you couldn't guarantee colocation, so you might be making DB calls cross-country. If you're using a poorly optimized ORM (untweaked ActiveRecord, Hibernate, etc.), that is issuing tons of queries, the net lag between the app server and the DB could slow you to a crawl.

The availability zones seem like the could be an answer to that, but they're being marketed as an answer to disaster recovery and failover. It would definitely be nice to request your app server and DB server are close to each other.

Yeah, I was going to use it for my online gambling (legal) site, and found the dynamic IP problem to be the real decision maker for me. I use smartfox server as a socket server, and renewing a license with a new ip address takes 24 to 48 hours, which means death to an online gaming site using social networking.

The static IPs make it possible to use AWS now. I can finally add voice chat functionality because of the power behind the large and extra large instances.
