This document summarizes a presentation titled "Software Architecting at Scale" given by Sergio Fernández, a Senior Software Development Engineer at Amazon. The presentation discusses trends in software architectures like monolithic, SOA, and microservices approaches. It covers challenges of scaling software and architectural patterns to handle increasing complexity. It also provides examples of Amazon's architecture practices like AWS services, the Architecture Center, and Chaos Engineering. The presentation promotes architecting with structure and Amazon's leadership principles.

- 5. Outline for today • Software Architecture overview • Trends in software architectures • Architecting software at scale • Professional opportunities • Q&A 5
- 6. Engineer vs Architect Can anybody tell me what’s the difference?
- 7. Traditionally architecture is defined as “the highest level concept of a system in its environment. The architecture of a software system (at a given point in time) is its organization or structure of significant components interacting through interfaces, those components being composed of successively smaller components and interfaces.” 7

- 9. Martin Fowler defines it “as a word we use when we want to talk about design but want to puff it up to make it sound important.” https://martinfowler.com/architecture/
- 10. Are Right, a Lot.
- 11. Desired features of any software architecture ● Feasibility ● Performance ● Reliability ● Testability ● Maintainability ● Extensibility ● Agility
- 14. Scaling problem Given a service with the following metrics on c5.2xlarge: • concurrency=1, latency: p90=20ms, p99=100ms • concurrency=10, latency: p90=120ms, p99=500ms • concurrency=20, latency: p90=200ms, p99=700ms • concurrency=50, latency: p90=800ms, p99=2s • concurrency=100, latency: p90=1s, p99=3s How would you scale it to 4,000 TPS (avg.) and 10,000 TPS (max.)? 14
- 15. 15 Monolithic SOA Microservices Single Unit Coarse-grained Fine-grained
- 17. Architectura l Patterns ● Client Server ● Layered ● Pipe and Filter ● Event Driven ● Microservices ● Peer-to-Peer ● ...
- 19. Distributed overhead ● Continuous Delivery and dependencies ● Integration testing ● New computation environments: containers, serverless, etc. ● Data partitioning and consistency ● Messaging: queues, pubsub, etc. ● Logging and monitoring ● Networking: load balancing, service discovery, etc.

- 22. an architecture requires structure

- 25. Amazon’s Leadership Principles ● Customer Obsession ● Ownership ● Invent and Simplify ● Are Right, A Lot ● Learn and Be Curious ● Hire and Develop the Best ● Insist on the Highest Standards ● Think Big ● Bias for Action ● Frugality ● Earn Trust ● Dive Deep ● Have Backbone; Disagree and Commit ● Deliver Results https://www.amazon.jobs/en/principles

Editor's Notes
- #8: There is no highest level concept of a system. Customers have a different concept than developers. Customers do not care at all about the structure of significant components. So, perhaps an architecture is the highest level concept that developers have of a system in its environment. Let’s forget the developers who just understand their little piece. Architecture is the highest level concept of the expert developers. What makes a component significant? It is significant because the expert developers say so.
- #11: architectures in software require to be agile, because architectures need to continuously evolve and adapt
- #13: Open-Close Principle
- #14: The trend goes to small components to maximize the features described before: smaller is easier to test and scale. Labra will describe in detail the different architectures.
- #22: “The traditional model is that you take your software to the wall that separates development and operations, and throw it over and then forget about it. Not at Amazon. You build it, you run it. This brings developers into contact with the day-to-day operation of their software. It also brings them into day-to-day contact with the customer. This customer feedback loop is essential for improving the quality of the service.” -- Werner Vogels in “A conversation with Werner Vogels” in ACM Queue, May 2006
