Performance is often one of the key focus points when building enterprise software. Many of the systems that we build rely heavily on communications with other systems. When these external communications become slow, then our software becomes slow. Unfortunately, we often have no control over the response time of the services that we depend on. However, we can optimize the way that we communicate with those services in order to ensure maximum performance.
Companies need to be thinking long-term before even starting a software development project. These needs are solved at the level of architecture: business owners want to assure agility, scalability, and performance.
If you’re a microservices developer considering communication protocols, choosing an event-driven architecture might just help you rest a little easier at night. With the right design, event-driven architecture can help you to create apps that are decoupled and asynchronous, giving you the major benefits of your app being both performant and easily scalable.

The development life cycles of applications in an enterprise environment often follow a common theme. An application begins life with a clear purpose in mind and over time has requirements brought in that cause incremental additions to the scope of the original concept. These additions could either be completely in sync with the original concept or perhaps the requirement just had no better home to belong in. As the application matures to an end-of-life state it has now grown far past its original intended purpose and is in dire need of a refactor — breaking down the monolithic beast into smaller and more succinct components.
I have seen cloud tech change a lot in my 10 years of experience. AWS and GCP were not the default choice a few years ago, and I have worked in companies that bought and installed physical servers. What a nightmare! And this is why trying out serverless was the natural next step for me. I think everyone should give it a shot, and I wanted to share my experience!

Typically, domain models and UI views are completely separated. A few years ago, we had a good reason to do so because the views were mostly made of imperative code. But now that we have functional UI libraries (e.g., React with hooks), wouldn't it be possible to gather everything together, and implement the views as methods of the models they represent?

Micro-frontends are the future of frontend web development. Inspired by microservices, which allow you to break up your backend into smaller pieces, micro-frontends allow you to build, test, and deploy pieces of your frontend app independently of each other. Depending on the micro-frontend framework you choose, you can even have multiple micro-frontend apps — written in React, Angular, Vue, or anything else — coexisting peacefully together in the same larger app!
