PHX DevOps Days: Service Mesh Landscape

Editor's Notes

• #2: Service-mesh technology promises to deliver a lot of value to a cloud-native application, but it doesn't come without some hype. In this talk, we'll look at what is a "service mesh", how it compares to similar technology (Netflix OSS, API Management, ESBs, etc) and what options for service mesh exist today.
• #4: How many people are embarking on projects to drive innovation in their organizations? How many people think those projects will succeed? How many people can predict the future? How many people believe their organization’s executives can predict the future?

• #11: One large database! We should focus on how we design our data models so that they can be sharded and distributed…. Focus on transactions, etc not 2PC

• #15: This concept of defining language, developing models to describe a domain, implementing those models, enforcing assertions, etc all happen within a certain context, and that context is vitally important in software. In common language, we are smart enough to resolve these types of language conflicts within a sentence because of its context. The computer doesn’t have this context. We have to make it explicit. And any context needs to have explicit boundaries. This model needs to be “useful” ie, it should be able to be implemented. Try to establish a model that’s both useful for discussion with the domain experts and is implementable. There are infinite ways to model/think about something. Balance both masters with the model you choose. Large complex domains may need multiple models. And really the only way to understand a language and model is within a certain context. That context should have boundaries so it doesn’t bleed or force others to bleed definitions and semantics. Bounded context: within this space, this is the context of the language. This is what it means and it’s not ambiguous. Central thing about a model is the language you create to express the prblem and solution very crisply. Need clear language and need boundaries. Anti corruption layers are translations between the different models that may exist in multiple bounded contexts. They keep an internal model consistent and pure without bleeding across the boundaries. Bounded contexts tend to be “self contained systems” themselves with a complete vertical stack of the software including UI, business logic, data models, and database. They tend to not share databases across multiple models.
