Is it normal for cloud server
Hi,
I'm never really using any cloud server on the market...
and with recent offer from Google and AWS,signed up and got the promo credit...
for AWS I'm using it only for my Glacier since EC2 is too much to compare with promo credit received(micro instance about $18 a month)...
so,now I'm using Google Compute Engine with the promo $1000....launching micro instance for almost two months now,left idle...weirdly enough for me when seeing the charge/usage...my actual disk usage is less than 1GB,or about 700MB default install Debian 7...but shown in billing is about 5GB and being charged for it...
df -h Filesystem Size Used Avail Use% Mounted on rootfs 10G 734M 8.8G 8% / /dev/root 10G 734M 8.8G 8% / none 296M 0 296M 0% /dev tmpfs 60M 112K 60M 1% /run tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 119M 0 119M 0% /run/shm
Nov 1 - Nov 30
Google Compute Storage Pd Capacity: 5.68 GB-month (Project:xxxxxxxxxxxxx)

I'm sorry if it's just me not knowing much about how cloud being charged...really appreciate if anyone can get me to better understand...

Do you have any swap ? How big ?
Nope....i created the instance,update ssh key(metadata),update os, then leave it idle....
# free -m total used free shared buffers cached Mem: 592 511 80 0 134 285 -/+ buffers/cache: 92 500 Swap: 0 0 0To me it seems your instance has a 10GB disk. So i don't know why you were charged for only 5GB.
I dont know how their cloud works, but maybe it has thin provisioning and only counts the actual used space ?
@rds100 I believe it's calculated for used storage.....
@Shamli they can't know what you have INSIDE the instance and it's hard to know how much you are really using, unless it's OpenVZ. But Mao is right, it could be thin provisioning and you are really using 5.6GB on their storage now.
@Maounique at first,I also think like that..but the actual used space is only about 700MB....not 5GB....
If you had in the past a larger usage, it will show as used space in case of thin provisioning, even if you deleted the extra data, and the swap partition if present is counted too.
I think I know from where the confusion comes, many clouds count the actual disk IOPS and they might say disk usage is counted separately, while in fact that is not space usage, it is number of IOPS in a time unit.
When you write to the disk, use the stupid dd speed test, etc. this actually allocates space on the thin-provisioned volume. When you delete the file after that, the space on the volume is not freed, because it has been written to and cannot be just discarded.
@rds100 is AWS also like this..?or usage really calculated on the ACTUAL usage...
and,nope..I have not done any test on the server....
@Shamli i don't know really, i expect that usage would be calculated by the allocated size. The fact that you are billed for less than 10GB seems strange to me.
maybe I should delete this instance and create a new one,and see how it goes....
That would be a good idea make no swap file and dont do any operation on it.
I am also curious, they charge per "provisioned" space whatever that might be...
This makes perfect sense if you've been billed by Amazon before. They show your "average" usage for the month, and since we're a little more than half way through November, then it shows just over half your storage allocation.
Additionally, Amazon does in fact bill based on allocated storage and not used storage. So by the end of the month, it will bill you for the whole 10GB.
thanks @petris , that should give some hints to me,but now it's about Google Compute Engine....
so,now i've deleted and create a new instance then:
let's see next month...thanks everyone...=)
