19:30 〜 19:55 How we built an easy-to-maintain web application platform with Amazon ECS Kazunori Kajihiro

Maintaining infrastructure is hard. Even with the use of AWS there are tons of things that you have to care about.
In this talk I will discuss how docker and Amazon ECS (EC2 Container Service) have made our infrastructure
and application deployment maintainable introducing our private PaaS called Barcelona, which is built on top of ECS.

20:00 〜 20:25 Writing Better Errors Laura Eck

At their core, all errors trigger the same question, no matter who encounters them: What’s wrong, and how do I make it work? At the same time, every error has specific target audiences that are interested in answering exactly that question - but possibly in very different ways.

Let’s explore how we can design errors so they give each stakeholder the information they need to fix the issue at hand, and how we can use them to make our software even better. Errors might never be something you look forward to seeing - but when they crash your party, they’ll at least know how to chat with the guests.
