1 You are not obbligate to use object storage: it can be used to store operating system images, volumes backup . The default openstack installation does not put anything in object storage: by default glance stores images on controller node.
2 I do not understand your question 3 For object storage (swft) look above (1). As far as cinder is concerned, if you do not install it, disk volumes are sored on computing nodes but you lose them when you terminate an instance ( this is called ephemeral storage) 4.Usually in images "cloudinit" is used: when you create an instance from the ubuntu image, a user called "ubuntu" is created with a ssh key you stored in your user on dashboard or you can set a user with a password using user-data in dashboard 5 look at documentation: in network nodes configuration files you must specify the controller node address 6 In openstack object store (swift) can contains volumes backup and instance images.Generally speaking in object store you can put photos, music (see file cloud services like amazon s3). Cinder is bock storage and stores operating system disks (like your labtop hard disk). If you start an instance from dashboard and you specify to use an image and create a volume, the image you specified is downloaded into a cinder volume.In this case if you terminate the instance, you do not lose data because the volume is not removed and you can start another instance from it 7 Sorry for my bad english :-) Ignazio Il giorno 11/ott/2015 15:27, "Ayushi Kumar" <ayushi.03ma...@gmail.com> ha scritto: > Hi , > > Thanks Nithish for the reply .However it is still unclear to me. > *Some of the questions whose answers are unclear and I am looking > forward to the answers.* > > 1. where we can not use object storage(if possible give specific examples) > > 2 .In my* laptop* ,what do I use ,*object storage or block storage* to > store my photos if opentstack is not installed. > > 3. if my openstack architecture does not have cinder and swift installed > then where does the image gets stored and how > > 4.
