The best software engineering conferences of 2021

When it came to developer (and other) conferences, 2020 wasn’t a very good year. Many were canceled, while others moved online. And much of what’s going to happen in 2021 is still unknown. One thing is for sure: As in 2020, some conferences will again be virtual.

However, whether virtual or physical, these developer conferences will present amazing opportunities for you to get some practical, technical content on topics from honing your DevOps skills to the latest on containers and microservices. You’ll also have the chance to learn the latest technologies and best practices, as well as discover new ways to solve complex development problems.

Here is TechBeacon‘s shortlist of the most popular software engineering conferences in 2021.
