You are Marvellous Super Genius

[@_rmc]

The best bit about studying Azure isn’t only the curated learn cert paths but also that John somehow manages to bring out a new view about a month or two ahead of my learning curve; the deep dive videos are the best way to get ahead quickly and then read the docs and get hands on at a slower pace. Excellent as always John. Always looking forward to what comes next ;)

[@robadobdob]

I've literally just picked up a task to convert our apps to use Managed Identity so this video has been a godsend for explaining the ins and outs of it.

[@Semtx552]

incredibly valuable info, cheers! Especially the start where you articulate the ent app / reg app / SP interaction. i still struggle with that bit. I will rewatch your video dedicated to that subject.

[@rgulamhussein]

Thank you for such a clear explanation John. Your video is worth a thousand pages of docs!

[@niraj7616]

Excellent, watching this with a cup of tea in cold England 🥶 👍

[@robannmateja5000]

Listened to this again for the second time (refresher). As usual, awesome content and presentation. Thank you!

[@gunknown370]

I'm studying for the az-500 and your content is just the best out there! thanks for this

Great way to spend a saturday evening: Watching John explain stuff you did not know before.

[@amirjsayes]

Simply outstanding! Very clear and very informative and enjoyable to watch 💪🏼 Keep up the great work

[@yasimatech9769]

Many thanks John, really learnt a lot from this session on managed identities in Entra ID (aka Azure). You've really nailed it in my head 💯

Great overview, excellent engaging teaching style. Thank you. Onward and upward!

[@NTFAQGuy]

Glad you enjoyed it!

[@a29miller]

Great Video! Gave me a much better understanding of this managed identity topic!!

[@wesleygyger1210]

Good stuff. I didn't know what I didn't know until I watched this. Thanks for helping me understand this.

[@expat64]

Outstanding session John! I knew a fair bit of this already, but you clarified the picture, as you always do, and filled the remaining gaps for me. This will also be invaluable training for my team! 🙂

[@NTFAQGuy]

Awesome to hear! 🤙

Thank you our brother.

[@atulpatel8708]

Fantastic video on Azure Managed Identities, thank-you so much !

[@NTFAQGuy]

You are welcome

[@rupeshchoudhary9237]

Great teaching skills. .loved the whole explanation Bit . I would love enroll for a course on whole azure series if any.

[@ranajitjana4030]

Too good. Thank you for the video

[@timurkalizhanov5281]

Very clear, structured and detailed explanation! Thank you very, very much for what you are doing!!!!

[@NTFAQGuy]

You're very welcome!

[@toddhu2498]

I struggle a long time how MI magically dealt all the headache in SP. read all type of docs but always the information is here and there. The IMDS AND MIRP is really the key, surprisingly this video can use 40min to explain all my question that I researched like 1 week..

[@JeremyTBradshaw]

That was really great! Thanks very much.

[@BhanuPratap88]

Thanks a lot great explanation of a very complex topic 👏👏

[@Mo-iu3jf]

Awesome video, thanks a lot for sharing

[@michaelmendoza9824]

Absolutely Excellent Azure Managed Identity lesson/explanation! John Savill, you are an Azure evangelist Super Hero!!! I truly appreciate you! MM

[@NTFAQGuy]

Thank you

[@user-sx9tk3yu5m]

John the way you explain is just amazing ; that whiteboard is the best i have ever seen, it has a true Power 😁>>>>>>>> thanks for these series

[@NTFAQGuy]

Welcome!

[@cnchandroo]

Thank you John for yet another wonderful session. It helped me to understand better how MI works internally and used with Azure resources for access management.

[@NTFAQGuy]

Wonderful!

[@fxylk]

Amazing 🤩

[@NTFAQGuy]

Thanks 🤙

[@MrZakiHaider]

Great. thank you :)

[@chaddoyle6911]

Super Cool Stuff! I’ve just started learning these concepts and your teaching style is quite good. I have a question that came out of this video and that is that recently I decided to use a system mi even though there were multiple resources that could benefit from a user mi. I think I did it because there were trade off(s). Is there a simple answer and if not would you consider talking about the differences or sending me a link where you have talked about them?

[@NTFAQGuy]

I talked about why use UA-MI in the video. Don't really have anythign beyond what I explained.

[@antoniemerks1375]

Thanks

[@omartin2009]

Excellent as always!! How do apps, once IMDS (in the example of the VM), gets the refreshed token? I guess as a dev (or a user of the VM), I'd have to manually get a refresh token (or code that to refresh the token every now and depending on the kind of resource) by doing some kind of CURL request (or PS or other method) because the token I downloaded at t=0 will become invalid at t=12h, right?

[@NTFAQGuy]

There is no refresh token. As I said in videos its app only flow with long lived access token. MSAL etc will take care.

[@stepbabe100]

John Why am I only discovering you now? Awesome training and wonderful white boarding that is sorely lacking in other training I have watched. Keep up the awesome work? Any insight into Azure Synapse ?

[@NTFAQGuy]

Glad you enjoy the content.

[@SteveBonds]

John does a FANTASTIC job of using named chapters to enable us to search his content for specific things. I found his data services video which has a chapter on Synapse this way. He also talks about how to search his channel in his recent "learning Azure in 2022" video, which is a great intro to how to use all this amazing content.

[@stepbabe100]

@@SteveBonds thank you much appreciated! I will go find that vid !

[@va55ag0]

Thanks again for another great video. Quick question about my scenario: My app is an API and, and therefore has its own App Registration (an identity!). It accesses Azure Storage accounts plus makes calls other APIs using Oauth 2.0 client credentials flows (I.e. I have to grant my app registration permission to the scopes of the other app registrations). In this scenario, would you still recommend using the managed identity to access the Azure resources? To me, it seems strange for my app to have multiple identities.

[@NTFAQGuy]

like all consulting i think it depends :-) there are resiliency benefits as i talked about but maybe the complexity not worth it for you to have multiple.

[@StarvedForTime]

This video saved my ass. Liked and subbed

[@cdoex1]

Thank you, this was a very good MI deep dive. But is it possible to have an even deeper dive? Regarding the IMDS endpoint in the example there were no authentication to that service present, so I guess that is handled some other way? The AppService MI sidecar uses some sort of internally injected private key for that) (In certain situations using the C# libraries for this, the proactive token refresh seems to not start after 12h, or half the token lifetime, but rather 5m before expiry, resiliency effectively defeated...)

[@NTFAQGuy]

I don't think a deeper dive would be of interest to most. I gave detail on how it works but really all you care about is in your service/language how to request it.

[@cdoex1]

@@NTFAQGuy Thank you, I managed to find the documentation that told the story on how IMDS worked and even posted the link here in a response to my comment above, but now that response seems to be missing.

[@NTFAQGuy]

@@cdoex1 I did include in the video description the link to the MS how it works. Links in comments are disabled so thats likely why not showing.

[@cdoex1]

@@NTFAQGuy Ah, of course, but who reads the description 🤦‍♂🤦‍♂ sorry...

[@NTFAQGuy]

@@cdoex1 lol

[@expat64]

So John, am I right in thinking that, in your VM scenario, anybody who can log into the VM implicitly has permission to use any of the MIs assigned to the VM, meaning you need to be aware that when granting somebody access to the VM, you are also granting them permission to use the MI, and if so, is this something that should be highlighted?

[@NTFAQGuy]

Right anything within that vm can use the MIs associated with it.

[@AleksandarIvanov69]

For the algorithm! 😁

Hey John thanks so much Can I buy you a coffee or can you please enable some method of contributing back to this channel

[@NTFAQGuy]

That’s very kind but I don’t want to earn money from this channel. It’s my way of giving back to the community which is why I have no adverts etc. Just help spread word of the channel and help it grow would be awesome 🤙

create explanation of managed identities, thanks
