When working in big companies like Grab, lots of times I’m just solving some simple CRUD.
Meanwhile, lots of my time needed to be spent upon different other things:
- make and review pull request
- fixing failures for functional test and unit test
- load testing
- integrated with the logging library
Turns out, there’re also other teams, solving the same problem again and again. This pattern has several issues:
- reinventing the wheel: multiple teams solving the same issue, is a waste of engineering resource
- no standard practices: each team has their own opinion, and this opinion highly depends on the one who implemented it. Different implementation may ends up with different problems
- incomplete solution: teams are busy implementing business requirements, and the adoption of those best practices would give time to the actual business need
Ideally, a business-logic developer only needs to care about the business logic. The best practices should be taken care by a team of engineering excellence people – define the patterns, the processes, the monitoring dashboards, and the basic engineering tools.
Heroku is one of such example: they handle the CI/CD, monitoring, auto-scaling, infra-upgrade for you, and you only
need to care about the pure business logic (while… still with some basic configuration to tell the tool on what you
need). By doing so, a basic level of separation of concern is achieved.
People often has different opinions, and opinions are usually subjective.
Therefore, what’s accepted by one might not be accepted by another. To make best practices acceptable, those patterns needs to be so obviously-good, so that it can becomes not only the best practices, but also the common practices; in the end, it would become the only practices.
