Nine of you we were here, I really appreciate it. So my name is jay edwards, I'm the CTO of a company called palomino DB we're a boutique. Consulting firm I was the lead database engineer for obama for america, and I was one of the first ten employees at twitter. So I have a lot of experience with scale and data in a lot of different ways. What I'm going to talk about today are some of the things you might not know about Amazon Web Services. Does anybody here use AWS good, don't ever use real hardware again.

All right that doesn't work, okay, so five things you need to know. If you use a VPC, your elastic load balancer can serve as an internally facing load balancer, which means you can use it as a mid-tier application or database load. Balancer s3 can now do apex redirects, which means you can host a root domain on it. If you use something like Jekyll to convert your fancy website into a bunch of static pages, you can basically absorb an unlimited amount of traffic.

One of the things we did at ofa was for a lot of our micro sites that we would put up in response to an ad or some particular issue, we'd host on s3, and if we got lucky and it became popular and all of a sudden, 10 million people clicked on the link it would work. Great cloud watch has an alert for a billing estimate and you can put some actions. You can automate things based on this alert.

So if you're worried about runaway costs, which is actually a legitimate, legitimate concern on something like Amazon, you can say hey if all of a sudden I start using twelve thousand dollars a month, start shutting stuff off and call me provisioned. I ops is incredibly better than the old EBS volumes that everybody used to use. The failure rate is it's at least an order of magnitude better. So, regardless of leading the the I ops or the actual bandwidth, it's much newer hardware and the failure rates are way low.

So if you have anything in production, even if you don't need some sort of dedicated throughput, you should use pifs anyway spot instance. Pricing is pretty often about ten percent of an on demand price, which is very significant savings and the reason this becomes important for you. You can use spot instances with auto scale groups now so in in response to some sort of demand spike, you can provision 20 machines at ten percent. The cost of your you know your regular fleet and absorb those kinds of costs.

Vpc is like virtual private networks for Amazon. It's really difficult to migrate from a regular installation to a VPC. You should use them from the get-go cluster. Compute instances really do have ten times the bandwidth they are worth it, especially for Cassandra. You might not need the 32 cores. You might not need all the RAM, but that interconnect is really high quality. Its Tim gig bi-directional.

Something that you learn. The hard way is that the various SDKs boto the Java tools and the console they have a wildly varying degree of coverage right. They don't all cover one hundred percent of the functionality, that's available, so you're going to find that sometimes you have to do something in the console. Sometimes you have to do things via the command line, reserved instances I find that a lot of people don't exactly understand how they work.

They think that they're, like a specific instance that you buy at this really heavily discounted rate, that's not the case they're actually like discount tickets and as long as you're in the right availability zone and it's the right instant size. These will be applied indiscriminately until you have no more reserved instance tickets to apply so for the most part, you don't have to worry about trying to manage your reserved instances, there's also a marketplace.

You can sell them back if somebody wants to buy them and, finally, heavy utilization reserved instances always charge the hourly rate for light utilization and medium utilization ones. If you turn them off, they don't cost you any money. Heavy utilization ones do which means that, if you're not using them, even if you sell them away to somebody for a cent you're going to save money and that's it so. Thank you very much. I've enjoyed talking to you and if you have any questions, please come and see me afterwards.
