Innovations are occurring in many different areas in the architectural landscape. At QCon we explore the major software architecture concepts focusing mostly on innovation and early adopter stages. Take a look at the following presentations and take away hard-earned architectural lessons on scalability, reliability, throughput, and performance. Expect the staple track "Architectures You've Always Wondered About" to be featured at QCon San Francisco 2020. Keep checking back to see this year's presentations.

Mind Your State for Your State of Mind

Applications have had an interesting evolution as they have moved into the distributed and scalable world. Similarly, storage and its cousin databases have changed side by side with applications. Many times, the semantics, performance, and failure models of storage and applications do a subtle...

Practical Change Data Streaming Use Cases With Apache Kafka & Debezium

Debezium (noun | de·be·zi·um | /dɪ:ˈbɪ:ziːəm/) - Secret Sauce for Change Data CaptureApache Kafka is a highly popular option for asynchronous event propagation between microservices. Things get challenging though when adding a service’s database to the picture: How...

Evolutionary Architecture as Product @ CircleCI

Organizations continually evolve their technical architectures in order to adjust to the changing needs of their business.  For example: systems must scale with increasing customer demand, tools must create efficiency in growing teams, and implementations are generalized to support...

Architectures That Scale Deep - Regaining Control in Deep Systems

We often hear about architectural "scale" as if it's one-dimension and linear. In fact, it is neither, and that's breaking our tools and processes. Where modern, microservice-based architectures are concerned, "large-scale systems" aren't simply larger versions of...

Secrets at Planet-Scale: Engineering the Internal Google KMS

We propose to discuss Google’s internal key management system for cryptographic key material which is a critical part of Google's overall strategy for user data protection. The talk will cover the design choices and strategies that Google chose in order to build a highly reliable,...

Paying Technical Debt at Scale - Migrations at Stripe

Migrations are both essential and frustratingly frequent as your codebase ages and your business grows: most tools and processes only support about one order of magnitude of growth before becoming ineffective, so rapid growth makes them a way of life. Two of Stripe’s most important...

Practical Change Data Streaming Use Cases With Apache Kafka & Debezium

What do you want people to leave the talk with?

Three things, mostly. One touches a bit on the outbox pattern. Friends don't let friends do dual writes. That's one of the points I would like to talk about. The next one, people should get an understanding of what it is in there for them if they would use the change data capture. What are the use cases? How could they benefit...

Evolutionary Architecture as Product @ CircleCI

What are your goals for the talk?

The goal of the talk is to impress upon people the relationship between their industry and the product they're offering, and the way in which they choose to build their software. As we grow as engineers and leaders, there becomes a stronger connection between the work that we do every day from a technical perspective and the...

Neil Williams Leads Infrastructure Team @Reddit

The Evolution of's Architecture

What's the focus of the work that you're doing at Reddit?

We're doing a mishmash of things right now. At the core of it is building an environment that allows the product team at Reddit to act. That is, stuff that the users want to see, and is something they can feel confident about shipping—and to let them do that as quickly as possible, while balancing that with performance.

Serverless and Chatbots: A Match Made in the Cloud

Who is the audience for this talk?

I'm talking to an experienced developer, but probably someone who is just getting started with chatbots (potentially hasn't even done anything with chatbots yet). If you're getting started (or you're wanting to scale up to something you've got) and you're trying to work out what you need to think about if...
