Azure High Availability | Cross Region

[@robb1267]

Great stuff, thanks Dean! We've been actively talking to our MS reps about this b/c we have this exact need.

[@AzureAcademy]

Glad it was helpful!

[@nephilimcrt]

'Cross Region Load Balancer' would be a good name for an indie band.

[@AzureAcademy]

I like it

[@sidzhang]

Congrats on your 30,000 subscriptions, Dean!!!!!

[@sidzhang]

I wonder why a global LB still need to be configured in one particular region.

[@AzureAcademy]

Thanks Sid!

[@AzureAcademy]

All resources need to live somewhere 😉

[@christianibiri]

Great information!!

[@AzureAcademy]

Awesome!

[@sathyar7078]

You are nicely explaining all Azure services and how to use in a detailed manner . But if you could cover more into practical by resolving any modern day use case it would be an added value .

[@AzureAcademy]

Can you explain that a little more? In the video I showed multiple web servers spanning multiple regions would have automatic failover…this is a modern day use case, so…let me know what more you are looking for.

[@Southpaw07]

This is great. Thanks Dean . just one question . Lets say at each region my lb uses VMSS spread across availability zones can i add global balancer as well? or is this an overkill to have both zone and region resiliency?

[@AzureAcademy]

Yes you can do that…and you should! 😉

[@mikebike1715]

Can you make a video on Azure control plane

[@AzureAcademy]

Thanks Mike...I will add it to the list

[@iamroot5500]

thanks Dean! good one!!!

Is there any video on how to keep the VMs synced, for example mysql databases? is there something automatic or we have to set up manually the replication? (but in that case, how to promote the slave to master and remove the read-only in case of failover?)

[@AzureAcademy]

Hey Sofia! The load balancer provides network connectivity for the VMs on port 3306. The active listener to that port would be the master server I don’t know MySQL but you would use all the normal tools you would have in any environment for MySQL. If you have a further question please let me know so we can dig deeper

[@amende8372]

Hi Dean, thank you for showing this great features. In wich case should i use a globaly CDN and why should i use a global loadbalancer instead? Thanks for great content. :)

[@AzureAcademy]

Think of a CDN like Netflix. A CDN is a platform solution where I am serving files (content) to the end users and I want to have GEO redundancy and keep the endpoint as close to the users as possible. Generally CDNs only require a storage account to hold your files. A Load Balancer is for Infrastructure...like Servers, web servers, database servers file servers etc. So depending on what application you have determines which solution you should use.

[@gniusx]

Very good video. Is there anything we can do to protect against failure of the region hosting the cross region load balancer?

[@AzureAcademy]

No, the cross region load balancer is a regional resource. The good thing is that all of networking in a region would have to fail before the LB stops working…but I will pass your question to the product team…maybe they are thinking about this too.

[@gniusx]

@@AzureAcademy Thanks for your reply

[@AzureAcademy]

Anytime!

[@varunraj9571]

Hi, I want to associate with azure app service of each region instead of using load balancer of each region, is it possible ?

[@AzureAcademy]

Do you mean you want to use web application gateways instead of azure load balancers? You can…IF your traffic is only on port 80 or 443 But if you are doing that…you should consider Azure Front Door…watch this and let me know what you think 👉 kzbin.info/www/bejne/bIGuaWt6ebpmgZYsi=lHXodEZxSDzB3RuA

[@varunraj9571]

@@AzureAcademy thanku, can I use traffic manager as well?

[@AzureAcademy]

You can…but in general if you are just controlling web traffic like port 80 and 443 you would use front door, Agway, or traffic manager… Anything else you use a load balancer

[@user-im9zp4yp9x]

5:20 How do you load balance between regions with AppGw?

[@AzureAcademy]

Use Azure FrontDoor kzbin.info/www/bejne/bIGuaWt6ebpmgZY

[@suvendupanda6130]

Hey Dean....can we use this for SQL always on cross region failover?

[@AzureAcademy]

Good question, yes you can but I do t think you should. DNN or dynamic network names are better for SQL always on and simpler to manager without the extra layer of a virtual load balancer

[@suvendupanda6130]

@@AzureAcademy Thank you

[@AzureAcademy]

Anytime

[@babustud]

Can we also use this feature with AKS ?

[@AzureAcademy]

Yes…but I would think about WHY you want the load balancer. There are several load balancing type services in Azure…just be sure you are using the right one for your needs

[@kvsc5914]

Please do a video about Service fabric

[@AzureAcademy]

I will add it to the list, thanks!

[@AzureAcademy]

+KV SC service fabric, or services fabric mesh? And what is your goal with that video?

[@kvsc5914]

@@AzureAcademy I want to know about service fabric mesh and use cases in real time

[@AzureAcademy]

real time...for what? Service Fabric Mesh allows you to manage multiple systems like containers...but what exactly are you hoping it monitors in real time and what is the use case?

[@kvsc5914]

You didn't mention anything about reliable crossover

[@AzureAcademy]

hey KV SC Reliable crossover happens automatically with the load balancer because of GEO Tagging. If the closest region went down then the next closest region would pick up the traffic automatically

[@AzureAcademy]

+KV SC it is built right in, nothing you need to do. If one region fails, everything goes over to the next region automatically
