We have a number of projects based on ADLA+ADLS Gen1 and we recently noticed that prices for Gen1 are not available here any more. Also ADLA isn't listed in the Gen1->Gen2 migration guide.
Googling brought no relief, so seeking for advise and insights re:
Will ADLA support ADLS Gen2?
Will ADLS Gen1 will be discontinued?
Will ADLA be discontinued?
1.As of now, ADLA does not support ADLS Gen2, there is already a user voice here. You can upvote for it.
2.For ADLS Gen1 will be discounted or not, there is a link about this as following:
As of now there are no plans to retire ADLS gen 1. However it's recommended to migrate to Gen2 as most of the latest features and improvements will be rolled out to Gen2.
3.Based on 1, if Microsoft supports 1 as per the user voice, then ADLA will be not retired. But not very sure.
Hope it helps.
Azure Data Lake Storage Gen1 will be retired on Feb 29, 2024. MS are not investing in ADLA.
Customers were recommended migrate Azure Data Lake Storage Gen1 to Azure Data Lake Storage Gen2 and ADLA to an alternate framework such as Azure HDInsight, Azure Synapse Analytics or Azure Databricks.

I have a requirement to process some big data and planning to deploy Databricks cluster & a storage technology. Currently evaluating Data Lake Gen2 which supports both object and file storage. The storage account (blob, file, table, queue) also has similar capabilities which can handle both file based and object based storage requirements. I am bit puzzled to go for an option because of these similarities. Can someone clarify the following questions please?
Except HDFS support, what else is a significant feature that I should use Data Lake Gen2 against Storage Account?
Storage Account v2 with Hierarchical namespace enabled == Data Lake Gen2. If so, can I use File System to create file shares and mount them in my VM as like Storage acc's File system?
For accessing data from Databricks, which one of these two will be better for big data workloads. I can see Storage account can also be mounted as DBFS which can still leverage the distributed processing.

Answer: There're also other benefits. In short, the benefits are Performance / Management / Security as well it's cost. For more details, you can refer to this official article.

Gen2. If so, can I use File System to create file shares and mount
them in my VM as like Storage acc's File system?
Answer: Of course, the ADLS Gen2 supports file shares mount as the blob storage does.

Answer: ADLS Gen2 can also be mounted as DBFS. And as per Answer 1, the better one should be ADLS Gen2.
Nowadays im using Azure Data Catalog Gen1
I saw that Azure Data Catalog Gen2 is in preview...
If i create a gen2, the cost is free?
Thanks
Azure Previews are at no cost. PREVIEWS ARE PROVIDED "AS-IS," "WITH ALL FAULTS," AND "AS AVAILABLE," AND ARE EXCLUDED FROM THE SERVICE LEVEL AGREEMENTS AND LIMITED WARRANTY.

What are the sources/datasets are supported in Azure Data Share?
Does it support?
Blob storage
Azure Files
Queues Storage
Table storage
Disk storage
Looking at step 7 here and from the REST API documentation, I believe currently following sources are supported:
Azure Blob Storage
Azure Data Lake Gen 1
Azure Data Lake Gen 2
I would not be surprised if more data sources are supported down the road considering the service is in preview currently.
I'm trying to locate Azure DataLake Store Gen2 using the Azure portal and for some reason cannot find it:
I've been searching the docs and the portal and cannot seem to find it, has anyone else run into this problem? It has been in global GA since Feb, so I don't think that's the issue. I've reviewed the docs for how to create a Storage Account, is that all that's needed to create the gen2 instance?
ADLS gen 2 is a feature of Azure Storage. When you are creating a Storage account, go to the Advanced tab:
Then enable Hierarchical namespace (this provides you ADLS Gen 2):
I have a question about the use cases of the different Azure storage services:
Azure Data Lake Storage.
Azure Blob Storage.
Azure File Storage.
what is the difference between these services? and when to use them since they all provide the same functionality (storage) on Azure's cloud platform.
You can take a look at this article: https://learn.microsoft.com/en-us/azure/data-lake-store/data-lake-store-comparison-with-blob-storage
I'd say main differences between Data Lake and Azure Storage Blob is scale and permissions model.
It really makes no sense to paste the whole article here. But you might want to look at Data Lake v2, which (as MS claims) is a mesh or Data Lake v1 and Azure Storage Blob: https://learn.microsoft.com/azure/storage/blobs/data-lake-storage-introduction
As for the Azure File storage its just an SMB share over HTTPS (and it not really fast due to being 1 "stream" only).
