Preventing long outages, meta-stable events, thundering herds, Denial of Service Attacks, resource or concurrency starvation, or noisy neighbor issues all depend on fairness and admission control. We’ll do a deep, interactive dive into practical techniques that prevent or mitigate real-world issues.

Join AWS experts Colm and Addy for an in-depth look at the AWS European Sovereign Cloud. Explore this new, independent infrastructure's dedicated architecture, EU-based operations, operational controls coupled with governance and legal framework that powers this cloud.

Distributed systems are made up of protocols, requests, retries, and feedback loops that can lead to emergent behaviors and metastable failures—even at surprisingly small scales.

Amazon has practiced DevOps, where builders build but also test and operate almost every aspect of their services, since before it had a name. In this session, hear how Amazon practices have changed and improved over time and what we’ve learned as builders and as operators.

AWS works with organizations and regulators to host some of the most sensitive workloads in industry and government. In this session, learn how AWS secures data, even from trusted AWS operators and services.

Every AWS service is designed to be highly available, but a small number of what we call Tier 0 services get extra-special attention. In this session, discover how AWS has built and architected Amazon Route 53 and the AWS authentication system, which is designed to survive cataclysmic failures, enormous load increases, and more.

Every day AWS works with organizations and regulators to host some of the most sensitive workloads in industry and government. In this session, hear how AWS secures data even from trusted AWS operators and services.

The AWS Nitro System is the underlying platform for the next generation of Amazon EC2 instances that enables AWS to innovate faster, further reduce cost for AWS customers, and deliver added benefits like increased security and new instance types. This session dives deep on the security aspects of the Nitro System, including AWS Nitro Enclaves.

When you’re starting out, or building small, it doesn’t always make sense to build things the way big tech companies build. While this is often true, the details make this decision more complex than expected.

At AWS we say that security comes first—and we really mean it. In this session, hear about how AWS teams both minimize security risks in our products and respond to security issues proactively.

It’s not enough to fix a bug or issue, we also have to dig in and find a deeper kind of fix that eliminates most bugs of that entire class. Failsafe design and defense in depth are nothing new, but in security, the tendency to add layers can backfire.

Every AWS service is designed to be highly available, but a small number of what we call Tier 0 services get extra-special attention. Come hear lessons from how AWS has built and architected Amazon Route 53 and the AWS authentication system, designed to survive cataclysmic failures, enormous load increases, and more.

The Amazon Builders’ Library is a collection of living articles that are written by Amazon senior technical leaders and engineers and that describe how Amazon develops, architects, releases, and operates technology. In this session, five principal engineers share hard-learned lessons from their experiences building reliable services at Amazon.

At AWS, security is our number one priority, and that applies to our open-source work too. Come hear about the techniques, tools, and protocols we’ve developed for auditing open-source software for security risks, how to mitigate these risks, and how we manage the tricky balance between openness and collaboration and handling embargoed security issues and critical fixes.
