Diagrams can help to illustrate complex concepts, connections and dependencies, but Confluence Cloud offers no diagramming functionality out-of-the-box. There are a number of add-ons in the Atlassian Marketplace that allow you to create and edit diagrams.
There are three well used diagramming add-ons available , of the three highest rated cloud add-on in the entire Atlassian ecosystem.is the
Data Privacy and Security
The Confluence Cloud architecture for add-ons means that add-ons no longer run on the same machine as Confluence, as is the case for Confluence Server. Gliffy and Lucidchart use traditional server-based architectures that involve passing your user authentication to their server, allowing transit of your data through their servers for save/load operations and actually storing your data on their servers.
One of the key issues with moving to the cloud is trust. Atlassian are investing heavily in security, privacy and compliance for their cloud operations. Establishing that trust level needs a lot of information, transparency and education. Repeating that process for each add-on vendor, in addition to Atlassian, is a time consuming task.
With draw.io, a stateless/serverless architecture is used. This means that your user authentication is only stored in your browser. It also means that when you save/load your diagrams that diagram data goes directly between your browser and Atlassian's servers. It is neither stored, nor transits through third-party servers for persistence operations.
draw.io is open source, you can inspect the code you are running at any time.
draw.io is also the only add-on vendor of the three to comply with Atlassian's Cloud Security Policy. That means we have fully tested processes for backups (easy when you don't store any data) and disaster recovery.
draw.io has status monitoring performed publicly by an independent third-party, Pingdom. Pingdom tests the draw.io site every single minute, 24/7, from multiple locations. Uptime in 2015 and 2016 was 100%, not a single minute of outage. draw.io is the only product of the three to publish these numbers.
draw.io is free to license with Confluence Cloud without support. Lucidchart is the most expensive per user, but their licensing is central, so for the cost you can use any of their integrations.
draw.io offers the option paying for the plugin within Confluence Cloud, in order to be eligible for support. If you are an occasional user, the free package offers great value for money. If you are a power user and need an SLA to cover functionality and data issues then our support package is the ideal addition to your free draw.io license.
You can create professional diagrams in Confluence with Gliffy, Lucidchart and draw.io, all of the editors are mature and well featured.
The key issues in a cloud environment are uptime, availability, portability and privacy. With draw.io, these principles are built into the product from the base, not as an afterthought.
