BlackRock is one of the largest investment management companies in the world. With a 30-year history and an impressive performance, the company does not shy away from the latest trends in cloud native infrastructure. In just 100 days, the BlackRock engineering team managed to roll out a stable and reliable production ready Kubernetes platform on Aladdin Data Science, for internal BlackRock data science and machine learning use cases.   

In this episode, Mike Bowen is the Director of Open Source and the Head of Aladdin Studio DevOps discusses BlackRock’s Kubernetes journey and highlights some of their roadblocks as well as successes.  

Background and history  

Aladdin, which stands for (Asset Liability and Debt and Derivatives Investment Network) combines sophisticated risk analytics with comprehensive portfolio management tools, trading, operations, compliance and accounting tools on a single platform. The platform is used internally as a service for BlackRock's investment business and is also sold as service to other asset managers and financial institutions. 

Transitioning to cloud native  

The objectives of the Aladdin Data Science application are to provide an easy to use user interface that can be accessed by both BlackRock internal investors and external Aladdin clients to take advantage of analytical data for portfolio risk analysis. The web interface replaced the complex installation required for individual user desktops and was the impetus for BlackRock to make the shift to a cloud native architecture. A team of 20 people working together managed to successfully roll out a new version of Aladdin Data Science on the Kubernetes platform in 100 days.  

The main reasons for choosing Kubernetes are that it is open source and that given the contributors to the project, the long-term prospects were good. Companies choose technologies that will be relevant in one form or another in another 5-10 years, and to the BlackRock team, Kubernetes at that time looked convincing to them. In particular, they saw that the number of non-Google individuals and companies contributing to the Kubernetes codebase had exceeded the number of Google committers.

The BlackRock Journey to Kubernetes  

Instead of a complete rewrite of their architecture, BlackRock integrated Kubernetes into their existing framework. The BlackRock team worked around corporate firewalls, implemented service discovery and also wrote a customized messaging protocol across several different environments. In the end, they gained the rewards of more rapid development and more frequent deployments with their decision to go forward with Kubernetes.  

Having run Kubernetes for a few years now, the BlackRock team contributes to several prominent open source projects. In particular, the team created Argo-events, a popular open source container native event framework for Kubernetes.
