Introduction to Cloud Computing

[@ashiks8470]

I am watching this video not because I don't know these topics, but I really like the way this guy talks. Really sound and clear.

[@aprylraye1976]

You're right, he is very clear when he's explaining it to us.

[@HungryGuyStories]

Yeah! He obviously spent serious buckazoids on his camera and audio recording gear. I'm just wondering what happened to the right audio channel, bleh...

[@Johnny206]

+Hungry Guy lol.. had my right ear plug in and was like wth!! plugged in my left then voila!

[@alphadiallo3362]

+Ashique Chowdhury Yeah better. Indian English is cak.

[@kamalm.mounir1212]

[@dgloria]

excellent for comptia exam

[@xonxt]

Probably because he keeps saying "excetera" instead of "et cetera". Also, the audio is only in the left channel.

[@guykaufman797]

Watching this in 2021 - this is pure gold! thank you!

[@love_exegence]

This guy is so god at explanation. He doesn't even need slides.

[@michaelross778]

He is so God. I know this was a simple typo, but it's my new favorite praise phrase.

[@thesickbeat]

Back in the day none of the teachers needed slides =(

[@tobiasfuchs7016]

Noone needs slides! We use them just because they are available today. You are telling a story. When you know the story you tell, you would be surprised how well your talk turns out when you give it without any notes and slides.

I was thinking the same thing, 1 year later lol

[@GoHealthy78]

I must thank this Eli the Computer Guy who actually went extra miles and was very clear. The best part was that he actually made an extra effort to summarize everything in the end that actually helped me refreshing everything. Great Job Eli. God Bless.

[@BoxingHacker]

Man I love your tutorials. I wish you made tutorials in programming and database admin. Its soo clear and precise. I was getting tired of all these tutorial made by people who's accent you cant understand or some guy in the basement who sounded like he was talking to himself. Or even worst one made with a guy using a vouce synthesizer app. Presentation is everything and yours is great !Great Job. Thanks

[@josephwright8689]

A very fine teacher here; qualified, comprehensive and impeccably articlated instruction. Well done! Impressive and rare. Respect.

[@kennykistler6735]

I'm 45 minutes into this video, and it is amazingly good. I was going to quit at the beginning because the audio is not coming through on both headphones, but I'm so glad I didn't! It is really impressive for Eli to be so clear and easy to understand based on just standing in front of a white board talking and occasionally drawing a quick sketch. I will definitely watch more of his videos if they're all this great.

[@anvarghafurov4914]

Eli has always been our favorite!

[@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.

hello sir, i love the way, you explain the things. fan of yours

[@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.

[@skytechbits]

Every marketing information for cloud computing points out the possible hardware failure that might happen. It is rare for hardware to fail. Also if the hardware does fail more than likely the data on the hard drive is just fine. The most important thing to consider when one considers cloud computing or onsite servers, would be control over your server that has all of your data on it. You either trust a cloud service to have control or trust control of the hardware/software by you at your location where you can actually see it there. Those decisions have to come from an evaluation of the business needs first. I believe a hybrid situation would be best most of the time, however, that is just my opinion based on my past technical experience. I come from the generation who actually built the server and then could see it running in front of me, so I believe in controlling your own data to only be saved at your location and in a backup. Of course you do need to always do daily backups no matter which one you choose. It is important to talk to a cloud professional about your own business operations, goals, and budget before making a decision. Also not being able to own the software you pay for does not seem right, especially after you pay more than what it would have cost to own it. Subscriptions provides lots of income to large corporations and is confusing people as to what the dollar is worth anymore.

[@fasteddylove876]

I agree. Subscription is really deceptive. Most people only think in terms of the next monthly payment. Let's say it's $20 a month. OK, no problem huh. ------------------------------------------------- Well that $20 a month is $240 a year. Over 3 years that same $20 a month is $720. Quite a bit of change for a single user. And quite a bit of money for the software publishers...who hopefully are maintaining that software, providing updates, getting rid of bugs.

[@DonGrinful]

I cannot believe I've just watched the entire 1 hour without getting bored! Congratulations Sir Eli! Well done...One of the few best tutorial vids!

[@rashmipanda8584]

Very good explanation , skill of presentation is Superb!!

[@adihardy316]

Probably one of the best tutorials ever created by mankind

[@preethamsalehundam8023]

guys i have a doubt! During time:43:20 or so in the video it ws told the management software like vsphere has the ability to switch between various ESXi servers.in case of power failure to ESXi server1 how can the management software access the harddisk to move the server to other backup server?

[@theguycalledbrandon]

salehundam preetham Hey I am actually a Presales Architect that supports VMware technologies. The ability to migrate a virtual machine from one host to another in the case of a planned migration is called vMotion it first copies the data that makes up the virtual machine and sends it to the other hosts server (storage vMotion), once thats complete it then replicates the memory state to the second host, ones its all syned up it shuts off the instance on the 1st host. In the event of an unexpected outage (power failure, flood etc) vMotion wont help you there is a technology called High Availability that can restart the virtual machine on another host in the cluster. This is a restart of the virtual machine and it requires server/host #1 and Server/host #2 to have access to the same shared storage (SAN, NAS). If each host/server is running off its own independant disks those disks will stop spinning if the server fails and you would be able to access the VM's files which make up the virtual machine to be able to restart it on another host. another solution to the above problem if the server all have internal disk is to replicate the storage from server/hsot #1 to server/host #2 on an ongoing basis, that way when host #1 fails the files for the virtual machines exist on host #2 and can be restarted and run on host #2.

[@sunitabnsl]

+salehundam preetham I have same doubt

3 yrs down the line and your tutorial is still relevant and helpful. thanks and big up for the good job.

[@David_Lloyd-Jones]

Eli, My clicking on the up thumb above right doesn't change the number -- so consider this a verbal thumbs up. Hell, lemme give you a straight out proposition: I wanna be on your side, and I want you on my side: you're not just competent, which is common enough, but you're sane as well, which makes for a fairly rare combination. Good an' good on yer! -dlj.

[@recycletreerpcondo]

This is perhaps one of the most clearly explained introductions for cloud computing and virtualization.

[@sudeepchatterjee5194]

sir , I would say you are just amazing in explanation !!!

[@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.

[@Nyyankee718]

would be great if all these videos had chapter markers

[@walid7885]

Great course, Eli is so knowledgable, makes you wonder how can someone have so much knowledge that is so diversified in the IT field.

[@shanpalaniram]

Very good explanation. @ 42.06 in the video, when power is down in one server, how can the management console(vsphere, vware) can transfer data from that server to another working server??

[@unclecrusty1991]

I was wondering the same thing. I dont understand how there is any time to transfer the data(assuming the vsphere has to copy or read the data from the dying server to copy it) to the new server.

[@yusufali4872]

I think the answer to that is that it is the management software that installed the OS and the configurations on the first machine in the first place..so it can again install it on another machine

[@kamranmustafa6261]

i think all server syn data if any server goes down other server 'll provide services...

[@sponge108]

clearly you did not follow his explanation of Fault Tolerance, which is a replica of the original VM being stream-lined at the same time. If he didnt actually say this, just look up VMware Fault Tolerance. This is the tech that allows a VM on a specific ESX host go down, and a live version of said VM be live on another ESX host.

[@zebcode]

Question @ 41:23: How does the management software pull a virtual computer from a power dead physical hardware? Is there a replication going on to all pysical servers, so that when one physical server fails it just connects to the other functional physical servers?

[@carlodurian3730]

Wow! Clear as a day without fail you always manage to make these topics!! Thank you for these videos!

[@elithecomputerguy]

It happens "automagically"... basically shadow copies of the VMs are continuously updated on other servers that have the ESXi installed, and so if one server fails there is some algorithm that gets run and another server simply makes it's version of the VM active. Take a look on VMWares sites. they used to have very good explanation videos on how all of it works.

[@abdulfaiz9469]

[@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.
