We mapped out 26 key cloud partnerships across Wall Street

  • Financial companies, from big banks to startups, are increasingly embracing the public cloud.
  • Preferred partnerships are cropping up between these companies and the industry’s four main cloud providers.
  • Insider has a compiled a running list of key cloud partnerships announced so far.

Wall Street has finally begun to embrace the public cloud, and it’s a buyer’s market.

The major public cloud providers — AWS, Google Cloud, IBM, and Microsoft Azure — are battling it out to win over financial institutions. This year alone has seen a wave of finance-specific business lines and offerings coming to market.

It’s an attractive opportunity for cloud providers, as banks look to lift and shift existing applications and data to the cloud to develop new features.

The timing appears to be right, too. Bank executives are digging deeper into their tech budgets and setting their sights on the elasticity, resiliency, and faster development times that come with the public cloud.

And while financial institutions typically work with a few providers to avoid concentration risks, an increasing number are stepping forward to publicly side with one provider as a key partner.

Here’s a breakdown of key cloud partnerships across Wall Street.

Amazon Web Services

Bank of Montreal

BMO’s early June announcement selecting AWS as its “preferred, strategic cloud partner” signaled the bank’s desire to increasingly migrate to the cloud. Its US retail business BMO Harris, commercial and investment banking operations, and wealth management are among the areas making the move.


Blackstone is in the midst of a firm-wide push to adopt AWS that will see the private equity giant migrate many of its applications to the cloud, CTO John Stecher told Insider.

Capital One

Capital One has been at the forefront of Wall Street’s adoption of the public cloud, tapping AWS as its predominant cloud provider in 2016. In November 2020 it announced it was the first US bank to become fully-cloud enabled after shuttering the last of its physical data centers.

Citizens Bank

Millennium Management

Millennium Management’s AWS-hosted public cloud tools have been key to the firm’s recruitment and retention strategy. With AWS, portfolio managers at the $52 billion hedge fund have been able to experiment and solve problems faster, and the centralized tech team has been able to deliver more customized tech to the diversified PMs at a lower cost, Millennium’s top cloud executive told Insider.


UK-based neobank Monzo currently hosts more than 1,600 smaller, core banking functions on AWS’ cloud, according to the provider, and has been built on AWS since the founding of the company.
