Health monitoring of the Service Fabric app upgrade

De­ploy­ing an up­date of any ap­pli­ca­tion can be risky, be­cause new code may con­tain new bugs. Unit test­ing is an ad­vis­able method of re­duc­ing the risk. How­ever, some mech­a­nisms de­pend on work­load. Some work­loads can be sim­u­lated eas­ier than others. Ser­vice Fab­ric pro­vides health mon­i­tor­ing af­ter the new ap­pli­ca­tion ver­sion is de­ployed to the clus­ter. If the new ver­sion is not healthy the old ver­sion is rolled back au­to­mat­i­cally. Set­t­ing up the pro­tec­tion against fail­ures caused by up­grades is rel­a­tively easy. Read more ›

How to secure Service Fabric cluster with an X.509 certificate

You prob­a­bly no­ticed that Ser­vice Fab­ric Ex­plorer is publicly ac­ces­si­ble and does not re­quire any user­name or pass­word. Ser­vice Fab­ric Ex­plorer al­lows mon­i­tor­ing and man­age­ment ac­tions like dis­abling nodes or ap­pli­ca­tion dele­tion. The clus­ter and its man­age­ment can be eas­ily se­cured with an X.509 self-signed cer­tifi­cate. Af­ter that the cer­tifi­cate is re­quired prior to ac­cess Ser­vice Fab­ric Ex­plorer or pub­lish­ing ap­pli­ca­tions to the clus­ter. Read more ›

Azure Service Fabric & Scheduled Tasks

Sched­uled tasks have many names. In Win­dows, it is tra­di­tion­ally called Task Sched­uler. In Unix-like en­vi­ron­ments job sched­uler is called Cron dae­mon. Mi­crosoft Azure con­tains Azure Sched­uler and Azure Web Apps have We­b­Jobs. Ser­vice Fab­ric has its own mech­a­nism called Ac­tor Remin­der. This ar­ti­cle ex­plains how to im­ple­ment them. Mul­ti­ple jobs could be encap­su­lated in a sin­gle as­sem­bly. Read more ›

Service Fabric cluster endpoints & Azure load balancer

Reach­ing ex­ter­nal re­sources from a Ser­vice Fab­ric clus­ter is triv­ial whereas reach­ing the clus­ter from the in­ter­net re­quires some con­fig­u­ra­tion. The vir­tual ma­chine scale set, ser­vice end­point and load bal­ancer comes into play. On the first sight, it could be seen as a com­pli­cated as do­ing a puz­zle, but un­der­s­tand­ing of mech­a­nisms un­der the hood helps to re­al­ize that whole pro­cesses is easy. Read more ›

Service Fabric Hello World

Start­ing with a con­sole app is sim­ple. Write a line of text to the con­sole is easy and the re­sult is vis­i­ble im­me­di­ately.

The most dif­fi­cult part is set­t­ing up your di­ag­nos­tics, be­cause cloud ser­vices does not have any user in­ter­face. Read more ›
