DevOps includes core practices such as planning and tracking, development, build and test, delivery, and monitoring and operations. These practices, along with DevOps tools and technologies, help automate the application lifecycle. Processes that used to be manual and slow for your teams—like updating code or provisioning a new environment—you can do quickly and continuously when you use DevOps tooling and practices.

So What’s it Do?

Project Scope
• Approval Management
- Ability to “approve” (promote) and “deny” (unpublish) applications
• Cross-site Application Promotion
- Promote apps cross-site to target stream(s) -- replace or duplicate options
• Roles
- Security rule definitions allowing for only certain users to approve/deny and promote apps
• Email alerts
- On new apps to streams
- On app promoted or denied
• Versioning
- Export apps without data and store in versioned S3 bucket
• Auditing
- Qlik® monitoring dashboard included that reads program’s logs

Why is it Different?
11
Common Solutions
• Scheduled or triggered externally
- Do xyz nightly
- Do abc hourly
• Polling
- Is this criteria met?
- Is this criteria met?
- Is this criteria met?
• Qlik External Program Tasks (chained or scheduled)
- Ok, this one isn’t _that_ simple
And quite frankly, simpler
12
The Event-Driven Difference
• Actions fire in direct response to events within Qlik Sense
- App is reloaded
- App is published
- New user added
- Task succeeds/fails
- … pretty much anything
Because we all love real-time

How Does it Work?
