amazon web services - What's AMI ImageType? -

-

The description-picture filter has an image-type, and an image type in the response, although there is no information about it , And no information can be found by googling.

There are three types: machine, kernel, RAMdisk, what do they mean?

If you use the AMI images provided by someone else only If you are, you can ignore them - you will only need to use the AMI identifier, for example.

A slightly more detailed answer: RAMDisk image (ARI) and kernel image (AKI) are used as part of the boot sequence of the Linux instance.

More Correct:

  • Hardware virtualized (HVM) examples include ARI or AKI Is not used at all. All boot sequence AMI is part of itself. It includes both the EBS and the Instance Store backed instance image.
  • Paraverchualized (running on XN like PV) EBS supported versions require an AKI, and the paravirtized instance-backed instance requires both AKI and ARI.

AMI is always unique, while AKI / ARIs can be reused. For example, 5413 AMI and ramdisk ari-a51cf9cc << 0> Aki-88aa75e1 used by the kernel image (by us-pre-1 in public images) 683 AMI these two images are provided by Amazon and thus they are trusted by others when they are constructing AMI. If you have an instance store / If you bundle a paravirtualized machine The ARI and ACI will receive the original AMI I plan to publish AMI so many people will reuse them.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
