At the end of 2020, Confluence DC users in China held a webinar and shared their experience. Here is the topics I shared.
I started using Atlassian products such as Jira and Confluence in 2012. I used to promote the system as a system administrator in 3 companies, including companies with 500 people, 2,000 people, and 40,000 people. The company currently employed has 8 years of experience in Confluence. In 2019, we upgraded from Confluence Server 5.10 to Confluence DC 6.15.
