Jeff - are the disks slower (but bigger) than the i3 versions?

It looks like the IOPS and throughput are lower at the top end (looking at the two release pages).


I am supposedly on a stay-cation this week. I'll ask the team to check this thread.


Enjoy your time off!


You see something greater than 2-million IOPS?


Yes - the announcement for the older i3 instances (https://aws.amazon.com/blogs/aws/now-available-i3-instances-...) claims 3.3M IOPS (presumably on the largest size, with 15.2TB) So it looks to me like these are larger, slower drives?


It used to be 3.3M IOPS on 8 SSDs and now it's 2M on 8 SSDs but significantly cheaper; I wouldn't be surprised if they've replaced MLC with TLC.


8 TLC drives could easily hit 3.3M IOPS before... i3 have 8 1.9TB NVMe SSDs max, right? A 2TB P4600(TLC NAND) has 610,000 random read IOPS max, so that's 4.8M IOPS right there. A 7.68TB P4320 has 427,000 random read IOPS max, so that's 3.42M IOPS right there over 8 drives... Maybe they went from TLC to QLC with these ones?


This seems to be confirmed by the IOPS numbers in the documentation:

Fresh Relevance | Frontend Team Lead | Southampton, UK | ONSITE We're a SaaS based marketing technology provider working with some of the largest brands in the UK, Europe and the USA. We're looking for a frontend development team lead to expand our team and drive the future direction of our user-facing admin site.

The ideal candidate would either have previous experience leading a team, or be a senior developer with mentoring experience looking to take the next step.

Experience with python / django would be useful, but good HTML / CSS / JS skills are a must, along with a strong sense for UI and UX design.

Experience with SaaS / marketing technology would be a bonus.

This role is based on the green and leafy Southampton Science Park, but we also have offices in London and Boston.

We just moved from Braintree to Stripe (they changed their relationship with Adyen and gave us ~ 6 weeks to re-sign with their new merchant provider or move away). We do all our recurring payments on Chargebee, so it was pretty painless when we eventually got the vaulted details securely moved out of Braintree.


I'm looking at using Adyen. Why do you need to use Stripe as well?


Yup, we've been using chargebee for about 4 years, can confirm they're great.

I'm assuming it's not a straight swap for the `websocket` package? https://github.com/theturtle32/WebSocket-Node


Nope, only ws <-> uws :(


Fair enough. It is probably not a huge rewrite to give it a try.

Mongo does have document-level atomic update operators, such as $inc: http://docs.mongodb.org/manual/reference/operator/update/inc...


Yes this was completely ignored by the article. This along with a 'where' clause can guarantee the operation will only succeed iff there is sufficient funds. I don't know if other NoSQL DBs offer these sort of atomic operators.

Which makes this statement seem particularly unfair: "The problem here stemmed from the broken-by-design interface and semantics offered by MongoDB." He seems to call out Mongo by name a couple times but doesn't say that the exchange was actually using Mongo.


Yes, sounds like a good idea (if you have control of the DNS)
