+# Interview Ali met Erik
+Maand opzegtermijn, geen haast.
+
+Noemt control plane services
+- keystone users projects
+werkt voor leaseplan, reason layoff
+
+migratie workflow:
+- legacy cluster
+
+Live migration, ceph shared, kan geen manier vinden om storage zonder intermediate host te migreren.
+
+Knows how live migration work.
+
+Explanation OpenStack, trace server create call:
+- keystone, service catalog, token
+- nova api, nova scheduler, nova conductor
+ - doesnt know individual, whole schedules server
+ - nova libvirt talks libvirt, creates vm
+ - host aggregates mentioned + flavor extra specs
+ - vm calls metadata @ 169.169... mentioned
+ - cloud-init
+- nova wants port -> rabbit -> neutron
+- neutron api, ovn controller
+ - ovn northd, nb, sb
+ - neutron ml2 plugin translates neutron to ovn nb
+ - northd translates nb to sb
+ - ovn controller reads sb and translate to ovs on compute

+ - *Realised manual labor and automated it*
+
+How do you feel about going more into a development role?
+- that's what im looking for, prefer to be making.
+
+Linux or windows experience?
+- check fs
+- processes
+- administrative
+- k8s many scripts
+
+How would you solve a problem where a VM is not starting?
+- Check nova compute for error
+- If ceilometer/logging check that
+- Try with nova-compute to restart if down
+- Reload instance (?)
+
+Have you ever had to go into openstack DBs?
+- Not really,
+- Do have SQL knowledge
+
+Do you know how to work with git?
+- yes, branch system current job
+
+**Why are you leaving your current position?**
+reason: different tech than banks
+same company HCL as in spain, change contract
+
+
+*Deployment, maintenance, and administration of cloud technologies
+VMware, Azure, Openstack.*
+**Does this mean workloads running on said clouds? Or does this also apply to managing infrastructure such as openstack?**
+
+*Bash scripting for Linux server automation.* **What sort of automation?**
+
+*Plan and execute migrations and patching from on-premises infrastructure
+to ING Private cloud (IPC)* **Can you talk more about what kind of migrations**
+
+#### Isabel questions to us
+
+What does the usage of openstack look like from customer perspective?
+- different kinds (brands, direct access)
+Own DC? yes
+Are you expecting me to create new components, or maintain?
