we had strange issue couple of times our azure service. have cloud service installed has web application running on it. the service created sometime around beginning of december , first deployment done time well. after did multiple deployments cloud service, (it happens couple of times now) sometime azure decides roll deployment initial 1 - 1 made 2 months ago. happened midnight once again , see files creation date on "restored" or "rolled back" instance 12/5/2013, seems date when did initial deployment. a question: 1) why happen? 2) how can determine caused rollback? 3) how can prevent rollback? or 4) how can make "snapshot" of cloud service when rollback happens, rolls latest stable image? thanks, denis how doing "after did multiple deployments cloud service"? doing via webdeploy or via rdp azure vm? paas cloud service vms stateless. code running website rebuilt original .cspkg uploaded. see http://blogs.msdn.com/b/kwill...

i confused following code. why compare both == , equals method? (validfolderrow.getbondtafoldertype() == null || validfolderrow.getbondtafoldertype().equals("null")) what's difference between equals() , ==? can tell me difference between validfolderrow.getbondtafoldertype() == null and validfolderrow.getbondtafoldertype().equals("null") ? validfolderrow.getbondtafoldertype() == null compares null (i.e. checks if validfolderrow.getbondtafoldertype() null). validfolderrow.getbondtafoldertype().equals("null") compares validfolderrow.getbondtafoldertype() string value "null" . note first comparison must done first, since if validfolderrow.getbondtafoldertype() null, can't call equals on (since throw nullpointerexception ). since || short circuit operator, evaluating first operand true prevent second operand being evaluated.
