> The bank, which has a $10 billion annual tech budget
Am I the only one completely befuddled by this number? What the fuck are they doing with these money and 200k servers? These are facebook numbers. For a bank. What?

- They have a reasonably similar number of users (a fraction, but a large one).
- Mistakes cost a lot, so they have to be a lot more careful. It's a lot easier to make money hacking a bank than hacking facebook.
- They have to comply with all sorts of regulations.
- They probably don't trust their own employees to not be trying to commit fraud.
- They have to parse data on a scale that is likely similar or greater than facebook's. To detect fraud/lost credit cards/.... To decide who to give loans to. To price insurance. To decide how to trade stocks. ...
- They have to run a physical fleet of devices in the field, outside of their control, that have to give people the right amount of money ~100% of the time.
At a glance I see that Facebook has something like 300 petabytes of data [0]. I've worked at a bank, my team had something more like 10, but I don't think much of it was things like video that are just naturally huge. BOA is also approximately an order of magnitude bigger than the bank I was at.
One rumor I heard while there was that there had been a bug in one of our mobile apps that had been costing us a million dollars a day in server time.
As for usability, probably a degree of incompetence, mixed with design-by-committee and legacy. Edit: It's worth pointing out that banks usually don't gain or lose customers based on their UX, so it's not something that the business optimizes much.
I don't think there is anything technically difficult about almost any of the consumer software facebook offers, except scale. The same applies here but exchange "scale" for "scale, reliability, security, and regulatory compliance".
You can get in to my account by verbally relaying my grandfather's first name over the phone. You can open a bank account with a SSN and no photo id. What security? Their "security" is a fraud department, much like our credit card industry.

This is not how transactions work.

All banks offer the same shitty experience. What does differentiate them if not their software? They offer literally nothing my local credit union doesn't offer.

No argument here, but facebook at least manages to hire designers and not impose weird non-sensical patterns of auth, like "Look for this image when you log in".
I've talked with info sec employees working in their Charlotte office, and have not been given an indication that they are slacking.
Gluing together layer upon layer of legacy systems that are so old & opaque they are essentially black boxes nobody dares remove or replace.
oh and that small regional bank that was acquired 4 years ago? Yep...they've got an entirely separate stack of legacy systems. And that other jurisdiction with different data laws? Everything is different there too.
It's insane looking under the hood of these things. How banks manage to not lose half the money daily is a complete mystery to me.
13 exchanges x 3000+ securities x 2 quotes for each security x 23,400 seconds in the trading day (with the very very very generous assumption that quotes only change once per second)
That’s the inbound data alone, now consider all the algorithms they have to run on it, the models, the strategies, etc.
And then to each of their several hundred institutional clients, they have to give a unique and dynamic price.
Again, this is only the sell-side investment bank, not even looking at their absolutely gargantuan consumer bank business
Tech companies also aren't subject to the same level of scrutiny / regulatory requirements as big banks, plus the need to support old processes and software, etc
I could turn this around and ask, why would Facebook ever need infrastructure on par with BofA? I'm not an expert on infrastructure, but given their size, revenue, market position, number of customers etc, there's nothing baffling about these numbers.
When you are collecting that much of an audit trail, that data transitions from being a problem to manage to the problem to manage.
I wonder how many bespoke Kafka work-alikes there are out there that are older than the authors of kafka.
- the instantaneous nature of things in today's world is bleeding into finance, where banks want to advertise/offer near instant access to credit, loans, etc. instead of turn around time of days. in order to do that, it helps a lot to basically unify data across tons of previous disparate orgs, shared infra, etc.
- cybersecurity/auditing/compliance can be very expensive to license or contract for and occasionally has to be run on company hardware due to legal issues
Are you surprised that a an organisation handling billions of real money, millions or billions of financial transactions, and decades worth of legacy systems, can make do with only as little in servers and software development as a social network?
Apparently BOA has 4344 branches so the local infrastructure costs will add up both for branch kit and the networking costs.
