The short version

  • Each has a real cost: Azure DevOps first 5 users free applies to Basic plan only; Test Plans users are not included in free tier; Longhorn there is no vendor and no SLA, so a production incident at three in the morning is your own problem unless you buy SUSE Rancher Prime support separately.

What people use each for

Azure DevOps

  • Source code repository management and version controlnot Longhorn
  • Test planning and tracking for QA teamsnot Longhorn
  • Artifact storage for packages and binariesnot Longhorn

Longhorn

  • An on-premises Kubernetes cluster with local disks and no SAN that needs replicated persistent volumesnot Azure DevOps
  • Edge sites where shipping a storage array is impractical and three nodes is the whole clusternot Azure DevOps
  • A K3s deployment where the storage layer must be light enough to run alongside the workloadsnot Azure DevOps
  • A team that wants snapshots and S3 backups of persistent volumes without paying per-node storage licencesnot Azure DevOps

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Azure DevOps

  • First 5 users free applies to Basic plan only; Test Plans users are not included in free tier
  • Storage pricing increases per-GiB cost as volumes grow, with no volume discount threshold below $0.25

Longhorn

  • There is no vendor and no SLA, so a production incident at three in the morning is your own problem unless you buy SUSE Rancher Prime support separately.
  • Synchronous replication across nodes means write latency depends on the slowest replica and the network between nodes, which makes it a poor fit for latency-sensitive databases.
  • Every replica is a full copy, so three-way replication consumes three times the raw capacity, unlike erasure-coded systems that are far more space efficient.
  • It is designed for block storage on modest clusters and does not scale to the node counts or throughput that Ceph or a commercial array handles, so growth eventually forces a migration.
  • Recovery from certain degraded states, such as a volume stuck detaching or replicas failing to rebuild, requires manual intervention and knowledge of Longhorn internals that is not widely held.

Answered from the vendors’ own pages

Azure DevOps: How much does Azure DevOps cost?

Azure DevOps Basic plan is $6 per user per month after the first 5 users are free. Basic + Test Plans tier costs $52 per user per month. Azure Pipelines add-on for extra parallel jobs costs $40 per job for Microsoft-hosted runners and $15 per job for self-hosted runners.

Source
Longhorn: Who do we call when it breaks?

Nobody, unless you buy SUSE Rancher Prime, which includes commercial support for Longhorn. This is the decisive question for production use.

Azure DevOps: Is there a free tier for Azure DevOps?

Yes, Azure DevOps includes 5 free users on the Basic plan. Additional free allocations include 1,800 free minutes per month on Azure Pipelines with a free parallel job, 2 GiB free storage on Azure Artifacts, and free access for Visual Studio subscribers and Stakeholders with limited functionality.

Source
Longhorn: How much capacity does replication cost?

Full copies, so three replicas means three times the raw capacity. Budget accordingly rather than assuming erasure coding efficiency.

Azure DevOps: What does the Basic + Test Plans tier add to Azure DevOps?

The Basic + Test Plans tier adds test planning and execution capabilities, browser-based testing, and centralized reporting features. This tier costs $52 per user per month compared to $6 per user for the Basic plan.

Source
Longhorn: Is it suitable for production databases?

For modest workloads yes, but synchronous replication adds write latency and high-transaction databases usually want something faster.

Azure DevOps: How is Azure Artifacts priced?

Azure Artifacts provides 2 GiB of free storage, then charges $2 per GiB for 2-10 GiB, $1 per GiB for 10-100 GiB, $0.50 per GiB for 100-1,000 GiB, and $0.25 per GiB for over 1,000 GiB.
