Sorry to be so off topic but does anybody know of a way to log back into an Instagram account..? I somehow lost my account password. I would love any tricks you can offer me.

[@christophervincenzo1831]

@David Brody Instablaster =)

[@davidbrody307]

@Christopher Vincenzo i really appreciate your reply. I got to the site through google and im waiting for the hacking stuff atm. I see it takes a while so I will get back to you later when my account password hopefully is recovered.

[@davidbrody307]

@Christopher Vincenzo It did the trick and I finally got access to my account again. I am so happy! Thanks so much, you saved my ass!

[@christophervincenzo1831]

@David Brody you are welcome xD

[@mohammedsafiahmed1639]

I think you should've mentioned additionally that ephemeral storage is the storage that comes on the physical host that the VM is spun up on. Since there are many VMs on a single host, no one gets to claim the disk space, and that's why its gone once you destroy the VM! Great video btw!

[@eric159tw]

Really appreciate your explanation. I've been watching dozens of tutorials and read many articles, and still don't get the differences between these storage types. You really use the easiest way to explain. Thank you so much!

[@sinasoltani730]

for adding some extra information to this video : difference between block storage and NAS ( file-based storage ) : 1- in file-based storage, you have a directory that is accessible from the network and formatted in a specific file system format like ( NTFS, ext4, ... ) that you can assign permissions to files or folders based on usernames and groups that is locally authenticated or by a directory service like Microsoft Active Directory and define quota or read and write permission. but in Block-based storage, you have raw and unformatted disk space that is accessible over the network and you can format it to any file system that your OS support. 2- if your OS is Unix base you can access (NAS) via NFS protocol and if your os is Windows via SMB protocol. both of them are over the IP network. but Block-storage is accessible over IP network or FC or FCOE network.

[@zachgoll]

Thanks for these additions!

[@psy237]

Yes thanks from me as well !! :)

[@cellpamend]

Holly Virgin Mary! A Caucasian US-American in the IT environment who actually is well-spoken! I know I may sound somewhat sarcastic but I swear to God that I had not listened to someone from the United States capable to pronounce correctly words/vocables like "Going to, Want to, kind of, Internet; have[got] to" whao! You did it for entire 90 seconds without eating your T's/D's before N's & R's. I have got to give you credit for being moderately well speaker afterwards despite the continuous "/un-narestdan/"(understand) -Oh by the way! thanks for sharing your expertise IN A CORRECTLY ADDRESSED WAY! VERY, VERY USEFUL AND TRUSTWORTHY INFORMATION.

[@adeoke3086]

Very, very good explanation. A few wishy-washy explanations on other videos and google searches, but Zach this explains these concepts well. Video length originally seemed long until I realised that I may never get a decent explanation elsewhere, so for me, it was a time saver.

[@horizonbrave1533]

Damn dude, thanks a lot. I actually hope you do more deeper dives into this stuff. I know you're a dev and as you say you "don't care" about the lower deeper knowledge but you explain it so well, and I really appreciate how you give us a very practical and real look at how this stuff looks like in real life, not just a quick explanation!

[@shankarck1707]

Honestly, this is the best explanation I have seen so far!! So much clarity after half hour is just amazing. Especially, the table at the end.. That helped a lot. Thanks!!!!

[@Nandhakumarbkk2003]

Clear and lucid explanation without all the jargons......very useful. Thank you

[@AlexandruTanase11]

I'm commenting just for the algorithm. Your tone and approach is what some big course providers out there should strive to achieve

[@harishbabu740]

Thank you for the clear explanation. The differences between these storage types has been killing me for a well. Keep up the good work.

[@FredMasoni]

This guy is a giant! Simple, clear and to the point.

[@Rahul-im9rj]

definitely the best video I've seen on the topic, and I've seen a lot. well paced and crystal clear. Thank you

[@xeygarz]

Golden video - you explained everything so clearly for someone who has little or no background in the topic, WHILE managing to go in-depth about the inner workings and practical uses. THANK you!! A+++++

[@joeseven4283]

As a non it person, I can understand what those storages are. Thanks for the clear explanation!

[@twesigyeronaldk]

Thank you Zack. Very good explanation. Have used Digital Ocean for a while but didn't know what you have been explaining not until today. Thank you for the info.

[@samahome]

Wonderful explanation of different storage types with excellent diagrams and pictures. Thank you.

[@kaniShruthi]

One of the best video about different kinds storage and its specific usage .. simply loved it!

[@anshikagupta4931]

Thanks, really appreciate the last slide about names each cloud vendor is giving them, kinda lost you in the middle when there was a sudden jump from NAS to SAN while discussing block/file storage differences . But kudos ! great work

[@theoneandonlyzulu3342]

Really clear explanation, just what I needed, cheers.

[@redheadrusskie]

Hands down the best explanation I've found thus far. Thanks a million.

[@susheelv12]

Best part I liked was about comparison across various leading cloud storages. Since each of them use their own marketing terminology and actual implementations are abstracted.

[@vaastavv]

Great explanation brother. All the other google searches just provided basic idea but not the exact architecture of the topics....keep up the good work!

[@matushka78]

The 2nd half of the video is so much better than the 1st half

[@abhinavtyagi7173]

this is the best video on storage that i could find on the internet.

[@jasmeenmalhotra2225]

Super helpful for non-IT folks like me,thank you.

[@charlestommo2778]

Great, Great, Great clarity in the presentation 👍

[@hariharamoorthythennetipan2190]

Very well explained and clear distinction between different storage types

[@eeriksp]

The table in the end is very helpful and clears away a lot of confusion.

[@MarcMcRae]

One of the most thorough explanations I've ever watched. Nice one!

[@MoJtabaYousefiii]

thank you for wraping up everything in one video 🙏

[@ronaldvaughan4117]

Best "aerial view" on this topic, I ever seen, or read about. It covered most storage options, just deep enough to understand without getting confused. Well done! - Concerning block storage, would you happen to know how to determine blocks size, based of average files size, for best read and write performance, using DAS device?

[@iftikharahmed731]

Excellent explanation on Cloud Storage and its types. I highly appreciate and thank you for the effort and time you put to make such an excellent video.

[@junxiao9196]

Excellent explanation for a very confusing subject! Way to go! Thanks

[@ariktoledano5152]

Thank you Zach for the thorough guide and the great efforts - you managed to explain the difference between the storages great work!!!

[@abhijeetchouhan7126]

Dude - This is the best explanation I've ever seen. Bravo

[@rakeshreddy4864]

Awesome explanation. Simple and clear

[@PrashantSharma-ql4yb]

Good video. I was expecting to get more of the technical explanation on the differences between file and block storage.

[@uemiduram52]

amazing video, explained every single thing I wanted to know on this topic, thank you so much

[@adityajain1989]

U explain in amazing and understandable tone..... Kudos

[@MrLASIE102]

Great video and very well explained! Not rushed, and with real-world examples makes it very east to follow!!

[@yark618]

Super useful. Prepping for an interview

[@umeshparkar7056]

Great explanation, as you mentioned googling is just confusing and trying to decipher the meaning especially in context of cloud computing. Thanks a ton! God bless you

[@j50313j50313]

Bro, this is the explanation everyone needs!

[@vivek.80807]

Great explanation, cleared much of the confusion other resources created for me.

[@Liamllr]

Love these IT tutorial videos from the perspective of a developer. Really useful. Thanks!

[@rajendrapatil3958]

Thanks Zach for taking efforts and clarifying our doubts!

[@tejas332]

very well explained. makes the classification of the three and the way each of these is accessed crystal clear! Thanks a lot!

[@Rbmsv]

Thank you! Thats the best explanation video i've seen so far! I hope you are some kind of a teacher because its awesome content! Cheers to you from Germany!

[@zachgoll]

Not a formal teacher, just enthusiastic about learning new things!

[@eeriksp]

Thank you! Finally one simple and sensible explanation.

[@SaraMapua]

I love how well structured is the video. Very good explanation thanks!

[@jinyuanfeng5230]

Great explanation. the comparison of AWS, Azure, Google Cloud is awesome.

[@psy237]

Yes!!! Your claim at the beginning keeps true... Perfect!! Not even IBM is capable! My head is finally clear again after all this irritating confusing content I just watched before this video :'D

[@sankalpsingha]

Thank you so much for such detailed info. This is the best explanation I have seen so far on this topic.

[@duonganphong7643]

well explained , thank you ! as junior infrasture engineer i was confused about

[@gautammahajan7065]

Thanks Zach. Please do share more videos like this.

[@hishamabulibdeh255]

That is a fantastic and wonderfull work. Simple and direct way of explanation with nice examples. Thanks and Big Like :)

[@sridharbandi88]

Very well explained. I was looking for the different types of storage in cloud and this is the best video which clearly explained that 👍 Thanks a lot

[@vipinkbhatt]

Very nicely explained. Great job.

That was a great video. Great explanation. Thanks.

[@sudiptabhar3161]

BEAUTIFUL Explanation , I do admit .. will help me a lot in DATA CENTER study,...Have some conclusion below, kindly go through So ultimately ALL STORAGES are "BLOCK STORAGE" at the Bit level, However depending on ACCESS TYPE these different types of storages comes into play i.e. file & object storages ....I THINK .. is it so ?

[@derickcelias]

Thanks, very clear explanation!

[@sandhyachittapuram1700]

Cleared my doubts about storage! Very well explained! Subscribed:)

[@omarfayyad1]

Thanks for sharing this, Zach. I appreciate the effort. Quite insightful and detailed - just what I wanted. Keep making more!

[@2kpravin]

Awesome... Awesome...Awesome.. Thanks for making and sharing this..

[@thomas-sinkala]

You are the best Zach

[@ting-chiehhuang6937]

High-quality video. Thanks.

[@yutahijikata7822]

That was very clear and easy to follow! Thank you!

[@VeeraVikis]

Precise explanation👌 Thanks a lot. Subscribed 👍♥️

[@rptechplex]

Very nicely explained. 26:51 it should be File storage (typo)

[@jamesbee2042]

Great explanation with just the right level of detail, thanks Zach!

[@ameyapatil1139]

Best video on youtube ! TY !!!

[@omarothman7078]

Great effort and great content editing/clarity. Thanks a lot!

[@nikhiljoy6559]

Great video and thank you for explaining it so well and it was worth spending 30 mins on this . really appreciate the effort.

[@maheshpoddar4065]

Exceptional presentation. Cleared all doubts. Thanks!

[@jnelly3426]

Perfect. The book explanation was so boring. This was a fantastic explanation!

[@satish1012]

Great Video! I think GDrive , Drop Box is based on Object Storage

[@reddy94903]

Very good. I would watch second time as I keep getting confused with these.

[@atiquerahman3766]

Amazing explanation, Thank you

[@daveturnbull7221]

Been trying to learn the differences between Volumes and Spaces on DO and getting nowhere. Now I understand!

[@aceofspades2014]

Excellent video!

[@anoops7974]

Thank you :) Great explanation.

[@swayamgupta3116]

Exactly what I was looking for. So the underlying storage mechanisms are of only types - block and object?? File systems (whether distributed/local file systems) are on top of block storage. File systems are not the actual storage mechanism at the physical level??

[@zachgoll]

Yes, exactly. It is very confusing! I thought the same exact thing before I started looking into it further. The file system is more of an organizational system than anything.

[@bhuvanadhakshinamurthy7646]

Great video!!! Explained the storage concepts very well. Keep doing more such videos..

[@Abddur]

At last I found the explanation. Thanks a lot..

[@aruiwale]

Fantastic video!

[@cyoo688]

very helpful; thank you for putting it together :)

[@otonielguajardo4593]

Great video!

[@aviivi1425]

Isn't it correct saying that the object storage can internally use volume storage to store data?!

[@GauravKumar-in5in]

That's a great video! Exactly what I was looking for! Thanks Zach. Need more such videos may be double click on each of them etc.

[@chromerims]

Thank you 👍 S3 really costs more than EBS? Kindest regards, friends.

[@deankinyua2365]

😄Very Good Video

[@josiah_maddux]

Great video, exactly what I was looking for. Just one thing that needs improved: Object storage is actually cheaper than block storage, not more expensive. At the time of this comment, AWS charges 8 cents per gig of block storage, but 2.3 cents for object. Digital ocean charges 10 cents for block and 2 cents for object.

[@nnvema]

Thanks for making it clear!

[@salehyousefi1099]

Grear Video, Would it be better if you explain how Ceph, swift and etc. are related to this story

[@rahulsharma5030]

thanks for nice video. When you select a 5gb of block storage? Does that mean we once 5gb of space from one disk or we get 5gb of disk from multiple disks?I mean in block storage data is stored in different blocks.So these blocks reside on same disk or different disk?

[@zachgoll]

If I understand your question correctly, it should be one disk

[@rahulsharma5030]

@@zachgoll i read some where that SAN provides block access to data.So it means data must be stored in different blocks that may be reside in different disks?Is it possible?

[@jagadeshsakhinana]

Thank you very much

[@faycalnabaoui9550]

great explanation!
