AWS re:Invent 2024 - Dr. Werner Vogels Keynote (Category Architecture)
A few weeks ago, Dr. Werner Vogels, CTO Amazon, spoke On AWS re:Invent with a story about the concept of simplexity, which he came up with 20 years at Amazon. The word itself is a combination of two words: complexity and simplicity. In fact, the whole thing is to make the products look just for customers, and all the complexity was behind the scenes. Werner talks about six principles and shows how they are applied in practice. Here are the six principles:
1) Make flexibility a requirement The only constant thing in our world is change, so designing systems to be ready for the evolution of technology, workloads, and user requirements. In fact, this is very close to the concepts of Continuous Architecture or Evolutionary Architecture. Both of these books were published in the Code of Architecture Club: 1 and 2 respectively 2) Break complexity into pieces This is the standard divide-and-conquer approach. Werner proposes to divide large and complex systems into smaller parts that are easier to understand, maintain, scale and, in principle, easier to manage. But it is important to combine them in a loosely coupled style. And the components themselves should be with high cohesion inside. I recommend reading John Osterhuth's book A Philosophy of Software Design, which we also have. stripper 3) Align organization to architecture Here Werner Vogel describes the application of Conway's reverse maneuver. In fact, we need to adjust the organizational structure to the desired architecture, which allows teams to take responsibility and ownership of domains, as well as allow them to work independently. I mentioned this earlier in my report.How to form a team structure for business needs" 4) Use a cell-based architecture design This concept is about using so-called cells to build separate insulated units that can autonomously take part of the load. It is important that they are small enough to have a radius of damage. (blast radius) It was not too high, but not too small at the same time to serve the maximum size of the request and get economies of scale. 5) Design predictable systems Werner proposes the design of predictable systems, which reduces the impact of uncertainty and allows for consistency in the payment of systems. 6) Automate everything that doesn’t require high degrees of judgment The goal is to default on automation of processes and the exclusion of human in the loop, and people are involved only when decisions are needed.
For the most part, Werner demonstrated these principles with the example of AWS S3. (Simple Storage Service)This is the case with Amazon Aurora DSQL.
