What is PaaS? How we should build a microservice architecture from the point of the platform? What components do we need in order not to impede product development?

Alexander will talk about what solutions in Avito are used to achieve the necessary values of lead time (under the hood). Provisioning tools, orchestration, network solutions, service mesh, storage and delivery of secrets, convenient development tools and tracing. All that came in 4 years.
