Web Hosting Talk : Web Hosting Main Forums : Cloud Hosting : Divorce!

I know - you clicked here thinking you needed to report this as belonging in the social issues forum

Well - its actually about cloud / virtualiztion. I saw a great article today that descrbed cloud / virtualizatoin as divorcing your applications from the hardware infrastructure.

What a great description!

It allows your applications to hook up with whatever hardware they want very easily depending on which one gives the best service and makes moving around from hardware to hardware very easily

It also makes keeping it up (your application) easier since it usually runs on better hard drives and can share multiple pieces of hardware at the same time!

After thinking about this I was like - wow this sounds like a guys dream - lol...

any way - I thought I would share an interesting thought I ran across on another list since there seems to be much confusion.

Have you given your applications a divorce yet?

Here is my problem with the cloud. For years we have worked hard to understand the limitations and opportunities with our hardware and tuned it just as we have tuned our applications to give the best bang for your buck.

Things like transaction logs being on separate disks on separate controllers for speed and redundancy. Paging onto separate disks. Things like teaming nics or putting real time backups or log shipping out a secondary nic. Essentially making sure everything works in harmony according to the application and business needs So now, after all these years we are good at it but along comes a "cloud" where I can get resources but have it seems little control over making sure that we combine where we should and separate where we should.

As I told my wife today, I don't want a divorce.

By the way where is that article.

lol, well said.

why do you think you would not have control of your hardware? You must be referring to the great shared clouds vs private clouds??

[Coolraul]

I guess that I am referring to shared clouds. I will admit that I don't know the difference between the two. Don't get me wrong. For utility webhosting clouds make sense to me but for a high performance app.. I just don't get it yet.

nice post, thanks for sharing

10 years ago administrators layout files on the outer or inner track of a harddrive depending on speed requirements. And yes there is a very big performance difference but nobody is doing it now! Just aggregate enough disks.
Same with the clould.

well on a private cloud you are not sharing your cpu hardware with anyone. It gives you the ability to move your apps around by drag and drop and manage your resources better. As well you can run on enterprise disk vs simple internal disk.

One of the big advanatages I see is high availability and or fault tolerance - in that if you lose a box the application will pick the least utilized machine in the group you have configured and move to it - vs now its a massive emergency.

A lot of advantages if you ask me.

Throwing more spindles is not the answer. Nor is just moving it to faster / enterprise class disks. I think I am talking about different applications than you guys are.

Jeff where is that article. Is there a link to it?

I will try to find it - it was on a linked in discussion. I think on a cloud group.

"Short stroking" does have performance benefits, but with SSDs becoming more readily available, anyone serious about IOPs will be using those.

We have ruled out cloud because we want our backups to be immediately available. I can imagine scenarios where temporarily the only network access is SSH and the backup copies on our server are the only ones available for a restore.
