Enter microservices
Learning about microservice-based architectures in 2014 made me realize that other projects had also been struggling with similar challenges (partly for other reasons than the ones I described earlier, for example, the large cloud service providers meeting web-scale requirements). Many microservice pioneers had published details of lessons they’d learned. It was very interesting to learn from these lessons.Many of the pioneers initially developed monolithic applications that made them very successful from a business perspective. But over time, these monolithic applications became more and more difficult to maintain and evolve. They also became challenging to scale beyond the capabilities of the largest machines available (also known as vertical scaling). Eventually, the pioneers started to find ways to split monolithic applications into smaller components that could be released and scaled independently of each other. Scaling small components can be done using...
