Re: [geclipse-dev] FW: Adding EBS
|
Salut Mathias
1. As there is nice sunshine outside, I thought about having a barbacue in
your garden soon! :-)
2. You summary is inline of our strategy. I don't see a very big difference.
Anyhow, I can see some more use cases in the field.
The more interesting thing is if there even is a use-case for browsing the
EBS content from the client-side?! As far as I understand EBS it is meant
to be a block device ready to be attached to a running EC2 instance. It is
like a harddrive connected to a running machine. So here are my thoughts:
1) Normally I do not want to have my harddrive attached to more than one
machine, regardless from if the machine is local or remote, server or
client side.
Why not having one harddisk attached to more than one computers. That is
something
like the "SAN/NAS" is doing. So it is not so uncommon. There will be
problems with
consitency management etc on Cloud provider side, but we will see what
future brings...
2) If I would like to have access to parts of my harddrive (databases,
remote mounts, etc.) from the client side I am providing suitable services
on my server side giving such access (like samba, database connections
etc.), but never ever I would like to give full access to the client side.
Anyhow, the owner of a few EBS block devices, I know at least one potential
user (me)
who will not be able to "track" the content of all EBS devices continuesly.
So meta-data will
be used to help the user to remember what is inside. But experience showed
that ... at some point
you just plugin your USB stick to the computer and open the Explorer and
look what is inside before
you open the application to access data on the stick.
I don't see the big difference in the use case's workflow between USB and
EBS!
But again....
So for a client like g-Eclipse I rather see use-cases like
1. Create/Delete an EBS volume
2. Attach/Detach a volume to a running instance
3. Create snapshots of the volume
4. Share these snapshots
This is what we need first and what is offered by Amazon currently. So we
are in agreement
and you have to organize the barbecue anyhow!
