Introduction to Cloud Computing

[PaRoDiEr1993]

What is said in 76 minutes can be said with just 4 words. Cloud is internet storage. There you've saved a load of time by reading this. Don't know why people say it's so easy to use, when these ITs are using terminology that only ITs understand, like environment? What the hell's an environment? Yeah, these ITs are just making things difficult, and its easier to say straight up what the cloud is, which again is internet storage.

this guy is great.thanks in advance :D

[Burnmoh]

Thank you very much , im studying Bsc Enterprise Network and Security Management , it was very easy to understand and useful to me , cheerz frm india :D

[kunalmawlikar]

Hi, Thanks for the tutorial. Please let me know if there is any tutorial for AD and exchange server.

[moonchaser2]

thank you very much!

ha ha ha ha "into the cloud"!!!

[sv00011]

Vaguely recalling, the mainframe terminals didn't have a mouse. (Sometimes a wired rod we would hit the screen with to probably read the twinkling green letters from the lead-gray screen.)

[chiragmukkati]

But what are the physical devices that can be shared on cloud.....still its a mystery for me...

[kamal872001]

the sound is work on the left speaker only

you have mic problem

any way tanks for you videos u have my THUMBS UP

[chiragmukkati]

@Eli...cloud concept that you have explained is great but only doubt wandering in ma head is that....how do you share HARDWARE on the cloud??

[elithecomputerguy]

@chiragmukkati Entire systems are controlled by Management Software that seamlessly moves "Instances" of operating systems from one physical box to another. This software can physically turn physical computers on and off, and move Instances based on the load and resources required by the Instance.

Great job Eli. Thanks a lot!!!

[ezekielthemack]

Thanks very much for your help Eli. Much appreciated.

[asm546rani]

very very good presentation, keep the postings Eli. very much appreciated.

[bigvnd]

You're very clear. Thank you so much

[dipesh2359]

amazing!!!!!!

[barathsharmaja]

i know what cloud computing is .... thanks to you !!

fabulous presentation

[djmaxx007]

great video. just wish you'd make the audio stereo. if it is, it sounds weird. not complaining just sounds weird lol

[djmaxx007]

Also, I cannot find a clear answer for this, even from VMware. When it comes to vMotion redundancy, I assume that a copy of the virtual machine is already on another (or all) ESXi server and it's synced. Because if not, and the ESXi hardware that houses the virtual machine you're using dies suddenly, then there won't be any time to transfer to another ESXi server. The reason I'm asking is because I'm wondering if every time I upload a new vm, will it take up space on all my ESXi servers?

[Dheedh]

The most EXQUISITE CLASS of all AWARD goes to  u : )

[sunilmaks8]

super introduction... would watch again & again & again untill I learn & get boared

[CanecaProductions]

OMG! I really needed this ESXi video THANK YOU!!

[pradeepaki]

i like the way you describe and its easy to understand..KUDOS



[LivParDzsterPrep]

Good stuff Eli.

I made a user profile just so I could like this one. Keep making the videos, and I will keep watching and Liking them.

[juplm4000]

My left ear enjoyed this.

[2keenan]

Thank you very much for this class. what a great teacher

[NUTZJ98]

WHOA!!! Left Speaker Only Fail!!!

[muzaffar700]

Thanks and Keep it up..

[surubasu]

Thanks



[davesvx]

GREAT JOB ELI !!!!

[Mephistos12]

Very informative vid but if the central network totally failed or was attacked then everybody could lose out not just individuals but everyone. I am also concerned about security and the data being used by Big Brother. He is easily watching you.

[Jjunior130]

dat left audio channel

[bleeveldt]

excellent class on cloud computing, i have a much better understanding. thanks much!.

[al97093]

why are you repeating simple matters over and over again?? esp. the terminal services server and thin clients. this circulation is slightly irritating...

[al97093]

though it's great in all other aspects..thanks!

[ranjancse26]

Thanks for the wonderful explanation.. it was really awesome.

[codydwyerify]

Eli, great information in these videos. I have a quick question about edge servers. If someone accesses your website (or whatever) and it get's transferred to the edge server, how many times to you have to pay for that? once a month, once each time the video is viewed?

[vaispatu2006]

Dear Eli, I like your presentation very much on cloud computing. My question is about clustering. Is it possible to form a cluster with servers that are in different location...like one server is in the US while the other is in Japan and the other in New Zealand? Or is there a limitation distance wise? I'm working on a project that connects Servers in different countries by mirroring databases... but it has a limitation of the amount of servers that can be connected. You did a great job.

[elithecomputerguy]

@vaispatu2006 It depends on the software you're running. You should be able to as long as you set it up properly and create and appropriate replication strategy.

[pagola]

@vaispatu2006 im not eli but what your talking about doesnt seem like clustered computing because it is not centralized. It seems liek you are talking about grid computing which is losely coupled

[vaispatu2006]

@pagola thank you for your help.

[heroics03]

Thank you! These videos are great.

[immuneDay]

cool videos bro, tanx

got a question tho, you said streaming videos is expensive for you on everymanit. Why dont you use youtube then, instead of standard flash player? Cons are mainly price and also mobile avaiability (iOS).

btw "virgins" at 52.43? xD

[elithecomputerguy]

@immuneDay When this class was created YouTube still capped video length at 15 minutes. I migrated to YouTube for content delivery a few months later....

[gocasy]

This is so awesome. Thankyou so much!!!

[learnanddeliver]

Thank you very much for this great detailed video.

[ms77462377]

.. I like your videos.. keep going...! now, I got my reason to spend time watching videos from u than wasting it to facebook... hell yeah! u earned a subscriber.. d-(^_^)-b

[howtoguro]

I kinda of see cloud computer as a redundancy. since technology is on a exponential curve buying 3 servers is wasting money because if the power block fails for whatever reason, then the cost is most likely less especially on the fact that cloud computing opens many security risks. Not by volume of viruses but by the content of a brilliant hacker much more accessibility is achieved. Just my thoughts

eli its amazing.

[WumiO]

Eli, this is great stuff. i look forward to more classes here. I'd like to investigate some commercially viable service(s)- something one can begin on a small scale. Any thoughts? Thank you.

[elithecomputerguy]

@WumiO The best "small" scale thing you could look at would be online backup. You can use RSync and Deltacopy which are free pieces of software to upload client data to your own server. Being that Comcast internet is about $60 a month and a 3 TB hard drive is around $200. You could setup a linux box with a massive hard drive for around $400, and just pay for internet that you probably already have. You can probably charge up to $20 per month per system that is being backed up.

[carelessninjakiller]

thanks for this informative video... i'm a little confused about the hypervisor though... if i install EXSi and connect to it via V-Sphere to configure / manage it... how are my users actually going to connect to the OS I install on the EXSi? Will they be thin clients? Thx...

[elithecomputerguy]

@carelessninjakiller EXSi is generally used for servers. So you would throw up a Windows Server 2008 Active Directory Server, or a Linux Apache Webserver on it and then client computers can access them normally for authentication or such. If you were going to virtualize desktops you could connect using Remote Desktop or VNC.

[carelessninjakiller]

@elithecomputerguy thx for replying... so then can one EXSi "farm" host multiple servers... Windows Server 2008 ADS AND Apache on the same EXSi? Also, say when a single Windows server is running on an EXSi 4-computer cluster is the load being distributed amongst the computers - so if one fails, the server runs on three but the load increases? or is load balancing something else and this just runs on one computer at a time? thx in advance.

[elithecomputerguy]

@carelessninjakiller Yes you put multiple "instances" (Operating Systems) on the same ESXi Host.

Clustering is a function of the management software. You don't get it for free. I think you get it at the $3000 price point. With their failover if a physical ESXi machine fails the Instances are automatically migrated to other physical ESXi servers in the cluster.

[carelessninjakiller]

@elithecomputerguy thanks eli.

[billarajinikar]

When i saw ads about cloud computing, what is this? and why we go for cloud ?? but now i got full idea from your class. thanks for your video...

But What about security?? We can simply trust them or any other ??

[elithecomputerguy]

@billarajinikar Security is always the big question... the problem most companies and people have currently though is that the security they have is crap... Most people do not sit in data fortresses, most have clunky old computers that haven't been backed up in years, have expired antivirus, and could be hacked by a bored 9 year old.... For them Cloud Computing is more "secure"...

If you have a digital fortress, then cloud security may be something to worry about.

[ravipalle]

awesome
