Self-evaluation• Does your current project have an abstract level applied?• Is the hierarchy well defined?• Does the project team understand these layers well?• If complexity becomes too large in one layer, will the team separate it from the view?• Is the team consistent across layers?• Will your project benefit from the abstraction layer? Great architects instinctively follow these principles. The rest of us must consciously apply abstract layers an

As long as there are things to repeat more than 3 times, consider whether automation is required.If you don't do devops, as your business grows and your system grows, you will eventually need to transform it from beginning to end. It is better to start the construction of the pre-design considerations, in fact, these things if you understand, the beginning of the good, do not waste too much time, but can save a lot of time, why not.

above two books are the classic masterpiece of rod Johnson, a must-read book for Java architects. Among the books I have recommended, I have read the most carefully and seriously. At that time, I almost read this book in an out-of-the-box manner, when I was a child, I picked up the lights and went to night to read Jin Yong's martial arts novels. The content in the book, as well as my own experience and knowledge, were thoroughly summed up. After read
