The Cost of Cloud, a Trillion Dollar Paradox by Sarah Wang and Martin Casado makes two main arguments:
Cloud is the “perfect platform to optimize for innovation, agility, and growth, but it comes at a cost; there’s a ‘flexibility tax’ for the nimbleness the cloud provides.” Therefore, it’s critical to make cloud spend a first-class KPI metric, and empower engineering to optimize from day one.
As a company grows, the pressure that cloud puts on its margins “can start to outweigh the benefits.” Therefore, Wang and Casado present the idea of “repatriating” cloud workloads — bringing all or most out of the cloud.
The short version is: You’re crazy if you don’t start in the cloud, but you’re crazy if you stay on it.

But I think it paints a picture biased with a series de logical jumps and do so ignoring other and probably bigger trends in motion. I would like to bring the case of a Brazilian banking that is repatriating. But, nothing coming back, but seeking Cloud citizenship.
Itaú Unibanco is the largest bank in Latin America with 407.37 US$ Billions in Assets. Milton Maluhy Filho, CEO of Itaú, highlighted growth as the main driver and technology as a way to do so, in an event in June, 2 called Itaú Day (this links is an official English dubbed version of it). At some point he says that they have 24M MAU in their app (again, a banking app).
Contract with AWS ([sic]AmazonWeb Services)
Ricardo Guerra, the banks's CTO made public a milestone: they want to move half of its capabilities to the public Cloud until the end of 2022, with a ten-year deal with AWS. Last year it was made public the contract only hinting that "a great cut" of its infra would go to the Cloud. Now the number has revealed to be 50%.
50% of the bank in the Cloud until 2022
It was mentioned analytics, machine learning, serverless, containers, managed databases, computing, storage and security – the whole deal. And they also publicly announced they are moving from monoliths to microsservices. The infrastructure for Pix, a new and more cheap payment released by Brazil's Central Bank is already in a microservices architecture, and the Credit Card operation as well.
Microservices
Last year, profits of Itaú because of COVID-19 and Brazilian market, felt strongly 35%. They made only 18.91 BRL Billions in profit. "In times of crises, some people cry — other people sell handkerchiefs", there's a saying. I would add, "...and then there are the banks".
For this they already hired 4 thousand new professionals. Until 5 years ago, the plan was invest in its own infra: the bank own that in 2015 received 3.3 BRL Billions, which if you take the inflation, would around 1 US$ Billion.
We are talking about call-centers, bank web and mobile apps and banking platforms.
Nubank, a Brazilian Unicorn, is also the largest independent digital bank in the world. It started with a credit card offering and now is turning itself in a complete bank, without one single physical agency. And runs on AWS.
I bring attention to these two prominent examples that are close to home to me and from one of the hardest markets in the world: banking. The focus on SaaS also leaves a lot of workloads of a far great Universe of companies using the public Cloud.
To frame the discussion: We estimate the recaptured savings in the extreme case of full repatriation, and use public data to pencil out the impact on share price. We show (using relatively conservative assumptions!) that across 50 of the top public software companies currently utilizing cloud infrastructure, an estimated $100B of market value is being lost among them due to cloud impact on margins — relative to running the infrastructure themselves. And while we focus on software companies in our analysis, the impact of the cloud is by no means limited to software. Extending this analysis to the broader universe of scale public companies that stands to benefit from related savings, we estimate that the total impact is potentially greater than $500B.
You can say I'm just a person random on the Internet, but these numbers are completely made-up. Right after state that the "point of this post isn’t to argue for repatriation", and then drops a bomb that leads to the trillion dollar paradox of the title. The only paradox in this case, I would say is that it was never existed first place.
I also recommend Zack Kanter Stedi's Founder and CEO analysis of the piece:
Zack Kanter@zackkanter
Excellent *financial* analysis of using *commoditized* cloud infrastructure (vanilla servers). It misses: i) the (long-term devastating) cultural cost of recruiting world-class engineers to do undifferentiated heavy lifting; ii) it's unfeasible to recreate noncommodity infra. 1/n twitter.com/martin_casado/…14:43 PM - 30 May 2021martin_casado @martin_casado[NewPost] Sure, Cloud is great. But we show it hurts share price of public companies on the order of hundreds of billions ... and they can economically justify almost any level of work (including repatriation) in order to lower costs (w/ @sarahdingwang) https://t.co/k6ytG6bVHs
So, again, I think nothing better than analyses actual use cases to get a better picture of what's going on or even the myths and narratives some people created based on their own limited dataset. The biggest bank in Latin America is moving on-premises to be 50% Cloud at AWS until 2022 and they invested a huge money and they had plan to expand but their strategy changed to embrace Cloud, and one of Brazil's Unicorn, also from Banking industry is Cloud Native since day one. If I was a VC, I would bet my money on Cloud citizenship and not otherwise.
