<div dir="ltr">+1 for making Murano Engine <-> Murano Agent communication plugable so that one can switch to Zaqar or anything else. However watching RabbitMQ development for years I know hard can it be to build efficient and reliable system and I'm just not sure Zaqar can compete with such battle-proven thing like RabbitMQ yet. The only advantage I see is multi-tenancy. But I do believe it can be relatively easy be implemented with RabbitMQ. At lease in Murano. Don't want to go off topic here. The main idea is to use <a href="https://github.com/rabbitmq/rabbitmq-auth-backend-amqp">https://github.com/rabbitmq/rabbitmq-auth-backend-amqp</a> and dynamically grant agent permissions only to his dedicated input queue so that it cannot access anything else. Not just other tenants queues but also queues of other VMs in the same tenant. In case of Murano we will not need to maintain additional secrets or databases. Neither it will be needed to create RabbitMQ users/vhosts as all of this becomes virtual. And agent will not be holding any RabbitMQ passwords at all<div><br></div><div> </div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><span style="border-collapse:separate;color:rgb(0,0,0);font-family:'Times New Roman';font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;line-height:normal;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;font-size:medium"><span style="font-family:arial;font-size:small">Sincerely yours,<br>Stan Lagun<br>Principal Software Engineer @ Mirantis</span></span><br><span style="border-collapse:separate;color:rgb(0,0,0);font-family:'Times New Roman';font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;line-height:normal;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;font-size:medium"><span style="font-family:arial;font-size:small"><br><a href="mailto:slagun@mirantis.com" target="_blank"></a></span></span></div></div></div>
