Azure Files

The best part of Azure Files is how little friction there is to modernize classic file shares. Native SMB and NFS support means older apps and mapped drives keep working, and we can enforce access through Active Directory without redesigning permissions. Azure File Sync is a standout. Branch offices get fast local access with cloud as the source of truth, plus tiering keeps edge servers lean. Operationally, it is clean. Shares provision quickly, snapshots give easy point-in-time recovery, and soft delete has saved us from accidental removals more than once. Private Endpoints and storage firewalls make network lockdown straightforward. Integration with Azure Backup is reliable, so we do not need custom scripts, and lifecycle rules help control storage growth. Performance tiers are clear. Premium FileStorage is great for low latency workloads and high IOPS, while standard tiers fit collaboration and departmental shares. Observability in Azure Monitor and Storage metrics helps right-size capacity and watch transaction costs. The combination of protocol compatibility, identity integration, and solid management features makes Azure Files an efficient way to run file services in the cloud.

The seemless file sharing accross cloud and on-premises environments making it very easy to lift and shift apps without code changes. The local caching and centralized cloud storage makes it very high performance and easy scalability

Ongoing management is very straightforward, as the service is fully managed and doesn't require much planning around IT resources and skillsets for file server maintenance, patching, and high availability/disaster recovery support. End users report that it's a very familiar user experience for those used to connecting to traditional file share servers and, as a result, the learning curve has been much lower. The Azure File Sync capability has enabled a hybrid model with our on-premise servers caching local hot files and our less-frequency-accessed cold files residing in the cloud, allowing us to address some of the latency and performance challenges.

Costs can creep up if you underestimate transactions and egress. A workload that is chatty with small reads and writes can look inexpensive on paper but end up pricey in practice without careful monitoring and right sizing. Performance ceilings are another factor. Per share throughput and IOPS limits are fine for most teams, yet certain engineering or VDI profiles can hit the wall unless you move to Premium and tune clients. Identity and permissions need attention. Mixing classic AD DS, Azure AD Kerberos, and legacy NTFS ACLs can lead to surprising access results until you standardize your approach. Migrating inherited permissions from older file servers is not always one to one, so you budget time for cleanup and validation. Private Endpoints are great for security, but the DNS plumbing adds complexity across hybrid networks. Azure File Sync delivers value, but the first sync of large namespaces takes time and cache warm up can be noticeable for remote sites. When users reopen rarely used archives, recall latency is visible. Backup and DR planning is better than rolling your own, although it still feels like a separate track you have to design carefully per tier and protocol. Finally, search and metadata experiences are basic compared to some on-premise NAS platforms, so power users sometimes miss those richer features.

this product can become costly as you go up in tiers. also certain azure file deployed in certain regions have high latency.

Some performance issues were experienced with the standard-tier storage options, requiring us to upgrade to the premium tier, which incurred some additional unexpected costs. The premium, while more performant, did not quite reach the same speeds as our previous on-prem storage solution. We encountered some complexities around identity integration with Azure AD DS as part of the initial implementation but were able to overcome those challenges. With the premium tier storage options, and some upgrades in storage size which were required and corresponding data egress costs for downloading files out of Azure, we experienced higher costs for the solution than initially expected.
