It’s a heartache, nothing but a heartache. Hits you when it’s too late, hits you when you’re down. It’s a fools’ game, nothing but a fool’s game. Standing in the cold rain, feeling like a clown.

When singer Bonnie Tyler recorded in her distinctive raspy voice “It’s A Heartache” in 1978, you’d think she was an oracle of sorts, predicting the rocky road that encryption would have to travel.

Just a year earlier in 1977 the Encryption Standard (DES) became the federal standard for block symmetric encryption (FIPS 46). But, oh, what a disappointment encryption DES would become. In less than 20 years since its inception, DES would be declared DOA (dead on arrival), impenetrable NOT.

Tidemark delivers enterprise performance management (EPM) software. What that esoteric acronym means is that Tidemark helps organizations take internal data they already have and use it to plan the future steps they will take, but also to assess the historical performance of their organization. Tidemark was founded only a few short years ago (in 2009, to be precise) but has already raised close to $ 120 million from a host of investors over multiple rounds. Tidemark is a good example of a new breed of cloud vendor, those that were born into a world already comfortable with cloud-based enterprise tools such as Salesforce and NetSuite. Because of this fact, Tidemark hasn’t had to invent a category; rather it has the somewhat easier job of delivering an existing product category but in new and beneficial ways.

Question by identity: Network admins only. Do you think cloud computing is real or just a catch phrase?
give reason why?
is this the future or just something more to the daily aspects of a administrator.

Best answer:

Answer by John S
I think its potential, but right now no cloud computing isnt “real”.

Give it 5 years and serious investment and it could be a serious technology with major use potential.

but right now, im just not convinced sadly.

Question by Cilixblade: Is slow response time on a network singlehandedly server sided?
Hey,

So, as the lucky little prick I am, I got into a beta testing service of cloud computing, into one of the gaming services. The problem is that when I try to get into this, I always get the same error: “Your network response times are unusually high. Please try again later.”

Apparently, that may be because I’m to far from the servers. Since I live in Norway, that may not be so weird. Though, I know something is messed up with my network.

Obviously the question is:”Is slow response time on a network singlehandedly server sided?”
If it is, well, the problem is obvious, if it is not, and my network may be the problem, how can I fix it and how can I check it? I’m pretty sure ping isn’t network response time.

Best answer:

Answer by Grimace
No because if the server was always the problem, nobody would be able to use it.

Try this: Go to Start–>Run and type in: cmd. When the command window opens type in: tracert x.x.x.x (where x.x.x.x is the IP address of the server you’re trying to reach). You will then see where the delay is taking place because you’ll get a list of routers between you and the server and how long each hop takes.

Enjoy.

Question by Nex-Ten: iPad Cloud Computing security app – What software works for cloud network security on the iPad?

Best answer:

Answer by Nathan
HidePad works exceptionally well for wireless network security on both WiFi and 3G. This, in turn, protects your iPad’s cloud computing environment with 256-bit government grade encryption:

http://hidepad.annics.com

It’s a VPN application for the iPad that supports encryption, data privacy as well as network integrity. It also doubles up as a mobile security suite for the iPad’s Safari browser.

Given the inevitable push toward cloud computing and Apple’s own iCloud initiative that allows wireless syncing of multiple devices, ensuring authentication and integrity of your network communications has become the rule rather than the exception.

Question by : Is there a way to share files with students without a network?
I’m stumped. My instructor want’s to have a file share on the network where his students can access files for class, but the I.T. director, my supervisor, says that he can’t use the network or use ad hoc between computers (any platform. The computers we’re using happen to me iMacs, others are Windows XP machines). The first reason is because with large files and multiple students essentially streaming data at the same time would bog the network down (it’s not a very fast network and the school can’t spring for infrastructure upgrades). The second reason, the ad hoc idea, is because there’s a policy against it. No ad hoc on school computers. It would be a workaround since we can’t use the school’s network, but policies are policies.

So now I’m wondering, other than sneakernet (which is what my instructor hates to do because it takes so long at the beginning of the class), what other ideas are there? I’ve found USB flash drive duplicators on Amazon, but those are Expensive (with a capital E, natch’). Maybe something can be done with a couple of 7 port hubs and special software that automatically takes control of those hubs as a poor man’s duplicator? I know there are software solutions for doing this one flash drive at a time, but I’m thinking batch duplications, several at once to cut the time it takes to push out the files to each student. This might not be the best idea, which is why I think I’m probably unaware of better solutions. The files being copied are close to 2GB in size, smallest being about 500MB. Video files. And of course, no use of the network, period. Even for cloud storage. Any ideas?

OK, there are a couple of options.

1.) PirateBox. These motherfuckers are badass. Sit the thing down and the little bugger is like a lil’ server, nomming up and puking out whatever the hell you want it to.

2.) A LAN network. Cat5e is cheap as shit (about 5 cents a foot), so you just daisy chain a bunch of switches and profit.

3.) Patriot Memory Xporter Rage. These have transfer speeds of up to 25 or so MB/s. It may not be as fast as the other options, but if you really must put on the running shoes, these are the way to go.

Question by ITMAN: How to create a private cloud computing network?
Hello,

I work for a non-profit organization with 6 different locations and each location as its own computer system. I want to have all locations to connect to ONE server, but still have there SEPARATE systems. Is there a way to setup a small private Cloud or is VMWare and VPN connection the only reasonable way to get this to work? Should I consider using a Linux server OS for this project?

Specs:
Servers- Windows Server 2K3 SBS
Workstations – Windows Xp and Vista

Thanks

Answer by Anon
You could buy dedicated connections (ones that don’t use the Internet) to accomplish this. VPN connectivity will be cheaper but also less reliable in terms of data throughput. It all depends on how much upfront and recurring costs you want.

Question by Manoj: Difficulty in Understanding Cloud computing network architecture?please help…?
I have been reading a lot about cloud computing network architecture,but i am struggling to understand the whole and over-all network set-up…

As far as i have been understand it consists of 2 end’s front end and back end…

I had easily understood about the front end,in a example i have found using or accessing a e-mail
service is a best example for “front-end” of cloud computing..

But things are not easy for me in the “back-end” technology of cloud computing,

I am struggling to understand the back-end transactions of the cloud computing,

Because in the back-end i have seen some middleware componetns and Also about the central server administers the system etc…

Also the servers and network infrastructure of the cloud are being linked from all over the world to from a “cloud network”,
how is this possible?

In simple i am totally confused at the back-end side of the cloud computing
especially on about middlewares,Central server Administer system and About linking and mainting of the cloud network…

I hope some networking guru or some one with good network knowledge will clear my doubt,

Also if possible point me to some nice articles or e-books for understanding the back-end technology of the “cloud computing”
Have some questions for you
please edit in your answer or looking for some 1 else to answer this…

Where does the middleware present in the back-end ?

In the control node or in some where else?

Also i have seen in the internet that ,Cloud computing technology have been used by companies like google,But also i have readed that it also poses a lot of security risks,

how a secured cloud network can be designed?

Also in the back-end of the cloud how servers and pcs from all over the world have been linked to form a cloud network?

hope some will answer these edited questions…
Thanks for making the things clear,but still 3 of my questions remains un-answered?

As we know the datas are stored all over the place ,it poses one of the biggest threat to the network security,what kind of security mechanisms they use to reduce these kind of security at the back-end of the clod network?

Also where is the middleware located on the back-end model?

Best answer:

Answer by JoelKatz
Every computer that is part of a cloud’s back end is associated with a control node. The computer reports its availability to the control node.

When work needs to be done, the front-end also consults a control node. It reports what works it needs to be done, how it will be paid for (if appropriate) and so on. The control node then assigns back end machines to the job and routes the assignment to them.

The “middleware” generally refers to the protocols and software that implement the interaction between the control nodes and the back end machines that do the actual work. When a new back-end machine is added to the cloud, it’s middleware that begins assigning work to that machine.

You can think of the middleware as being like the cashier and the manager at a fast food restaurant. It takes your order, tells you how much to pay, and bills you. And it hands your order to the various people who make your food. When a new employee shows up, it tells them what to do. It opens the doors in the morning and locks them at night.
