How do you secure one tenant's information from another tenant's users? How do you keep operational costs low? How do you monitor and manage this stuff? In other words - how do you keep the neighbors happy?? In this session you will gain practical architecture tips and tricks for architecting multitenant SaaS applications, learnt from migrating real applications to the cloud so that you won't have to learn them the hard way, along with implementation tips and tricks on Microsoft Azure.
