There is a very important product that you have complete control over: you. Your skill set, your personality, your overall career is completely within your control. Those are all features of your product and it’s on those pieces that you need to iterate and improve.
Good products are successful often because they have good product managers. It is up to you to decide how you fit into the world and what people are demanding of you.
When reading Clean Architecture by Robert Martin, I came across a chapter of the same name. In it the author describes this “idealized” architecture structure where business and application logic are at the center of the diagram with outward rings surrounding it describing interactions with various frameworks and IO devices.
This architecture can also be known as Hex Architecture or Ports and Adapters Architecture, all having a similar design where core business logic is independent of the IO interfaces surrounding it allowing for architectures that are independent of frameworks, ui, and databases.
At the beginning we all start building an application. Then some part of it takes off and before you know it you are throwing new pieces on the original application until it becomes unweildy. Thus is born the Monolith. In time your system gets large, cumbersome, and hard to maintain. Then you hear about microservices (or maybe you started that way because it was in fashion when you started development) and start building them.
