The animal must be at least eight weeks old and must stay in the kennel under the seat in front of you. Kennels may not exceed 19x13x9 inches, and pets should be able to stand up and move around comfortably.
Airbnb was able to complete its entire database migration to Amazon RDS with only 15 minutes of downtime. This quick transition was very important to the fast-growing Airbnb because it did not want its community of users to be shut out of its marketplace for an extended period of time.
