Where is the sole number used for authentication? We got the same number in Sweden but the number is not secret, you need it combination with something else like an ID, signature, digital signature etc.

Thanks for pointing that out! We would, of course, love to have female speakers on the summit. We had an open call for talks, which was promoted on the web, Twitter, newsletters etc., but there were only male speakers applying, unfortunatel

> This initial approach, at least, does not cache the intermediate CNAMEs nor does it care about the CNAME TTL values. That's a total violation of the standard and will break A LOT of things. Example: my.domain.com -> CNAME ec2-1

Setting up Dovecot (with master-master replication) and Postfix (+ spamassassin, dmarc, SPF) isn't too bad. There's a lot of dated guides out there though. Stick to the man pages as far as possible.

10k/s is no problem for RabbitMQ, even on aws t2 machines. Where did you get that from? 50k msgs/s is no problem on an aws c3.xlarge instance (single queue, auto-ack and transient messages).

Finally, it's crazy that they've haven't implemented this earlier, and why isn't it enabled by default, like on GCE? We've had for a long time an app that just polls the ec2 api and looks for impaired instances and

True, just trying to balance the overly positive comments, without spending a lot of time laying out arguments.

No, if I choose Sequel ( http://sequel.jeremyevans.net ) I want to use all the power it gives me, not some lowest common denominator.. Also not all projects needs models, you know, there's other data access patterns..

Ok, yes, in the case where you have to have all information on one page. Another way is of course to get that information in a ajax call, or open a SSE/Websocket connection to listen for events from the event bus. But there are of cour

If you use a message queue system like RabbitMQ, and simply publish messages as JSON you have interfaces, authentication etc. done already. We have 17 different services internally, in four different languages, all communicating over AMQP w

It depends how you do SOA. We try to publish "events" rather than to "call" another service and expect responses. We try to decide as much as possible in the service that publishes an event, so that information doesn&#x2

We use SOA a lot, we have a RabbitMQ server/cluster in the middle who all services communicate via. We have applications written in Ruby, Go, Clojure and Node.js, all publishing and subscribing JSON messages. Benefits over monolithic:
