“The company builds its apps in Docker containers. Apps that need to stay on the company’s premises run on an OpenStack private cloud. Amazon Web Services and Microsoft Azure are used for public cloud. Fidelity uses a combination of cloud-native management tools like CloudFormation for AWS, Heat templates for OpenStack, and Terraforms, which runs across both public and private environments. It uses Cloud Foundry as a PaaS layer that spans both public and private clouds, too.”
According to the Fidelity study, the average investment return of the people who ended up with $1 million in their 401(k)s from the middle of 2000 to the middle of 2012 was 4.8%. That might sound doable. But remember that between 2000 through 2012 there were two market crashes. Over the same period, the average return of the stock market was 1.3%. So, to become a 401(k) millionaire, you had to do three times better than the stock market over the same time period
Good luck storming the castle!
