Lessons learned

• Don’t get too far in front of vendors• Mulesoft – support generally good, but long wait

times for some fixes• Mulesoft – upgrades more difficult than expected• Mulesoft – needed framework for efficient

development• Instructure – API issues… Questionable design

choices, bugs, throughput problems, documentation• Instructure – overburdened test environment
