VMware Tanzu is Broadcom's Kubernetes and modern application platform — and it has undergone significant restructuring since the acquisition. Product lines have been consolidated, pricing has shifted, and several Tanzu components that were previously included in VCF have been repositioned as separate purchases. This guide explains what you're actually buying with Tanzu, what changed, and how to control the cost.
Before the Broadcom acquisition, VMware's Tanzu portfolio was diverse — a collection of complementary Kubernetes and cloud-native platforms acquired from multiple sources. Pivotal Cloud Foundry (PCF), Tanzu Kubernetes Grid (TKG), Tanzu Mission Control (TMC), Tanzu Service Mesh (TSM), Tanzu Observability (TO), Tanzu Labs, and Tanzu SQL represented different entry points to cloud-native development. Some customers licensed all of them; many licensed subsets based on their specific use cases.
Broadcom's acquisition in 2023 initiated a consolidation strategy. The company unified TKG and TMC into a single product called Tanzu Platform, deprecated Tanzu Observability in favour of its own Aria Operations suite, repositioned Tanzu Labs as a separate consulting service line, and continues to maintain Tanzu Application Service (formerly Pivotal Cloud Foundry) as a legacy platform — but with substantially increased pricing and a clear signal that new workloads should migrate to Tanzu Platform.
The strategic intent is clear: Broadcom wants customers to consolidate around a single Tanzu Platform subscription, priced on a per-core basis aligned to VCF, with add-on services (consulting, training, professional support) sold separately. For existing TAS customers, migration to Tanzu Platform or cloud-native alternatives has become a critical decision point.
| Tanzu Product | Old Name / Pedigree | Status Under Broadcom | Pricing Basis | Included in VCF? |
|---|---|---|---|---|
| Tanzu Platform | TKG + TMC merger | Primary offering | Per-core subscription | No (separate subscription) |
| Tanzu Kubernetes Grid | Acquired from Heptio | Merged into Platform | Per-core subscription | Partial (vSphere with Tanzu only) |
| Tanzu Application Service | Pivotal Cloud Foundry (PCF) | Maintained but strategic shift | Per-instance or per-core | No (separate subscription) |
| Tanzu Mission Control | Greenfield acquire | Merged into Platform | Per-cluster subscription | No (part of Platform pricing) |
| Tanzu Service Mesh | Acquired from Tetrate (originally Istio) | Maintained; now part of Platform | Per-core or per-cluster | No (separate add-on) |
| Tanzu Observability | Acquired from Wavefront | Deprecated | N/A (end of support) | No (use Aria Operations) |
| Tanzu Labs | Greenfield consulting | Separated; consulting services | Time and materials | No (separate engagement) |
Broadcom is consolidating Tanzu from a portfolio of specialist products into a unified platform subscription. This simplifies the commercial model for Broadcom but requires customers to adopt a "one size fits all" approach — paying for platform capabilities even if they only need a subset. The deprecation of Tanzu Observability signals that Broadcom intends to cross-sell its enterprise monitoring stack (Aria Operations) to Tanzu customers.
Tanzu Platform is Broadcom's unified offering for enterprise Kubernetes and modern application development. It combines capabilities from TKG (Kubernetes provisioning and management), TMC (multi-cluster governance), and TSM (service mesh), positioned as a single subscription that abstracts away complexity.
In practice, Tanzu Platform licensing works like this: you purchase a per-core subscription, priced similarly to VCF but as a separate line item. The core count aligns to your vSphere infrastructure (or your standalone Kubernetes infrastructure, if you're not running vSphere). You get:
The problem: you pay for all of this regardless of how many capabilities you use. A customer deploying Tanzu Platform purely for Kubernetes cluster management and governance doesn't get a discount for not using the service mesh. The per-core pricing model aligns Broadcom's incentive structure with yours — more cores = more revenue — which makes it particularly important to right-size your Kubernetes node topology and challenge whether the full Tanzu Platform feature set justifies the cost.
Tanzu Platform per-core pricing ranges from $3.50 to $8.00 per core per month depending on commitment term and support tier. For a 100-core Kubernetes infrastructure, annual Tanzu Platform cost could reach $42,000 to $96,000. This pricing exists in addition to VCF licensing if you're running Tanzu on vSphere, creating significant cumulative costs.
Tanzu Kubernetes Grid was originally VMware's distribution of upstream Kubernetes — a hardened, vendor-supported Kubernetes distro that could run on vSphere or public cloud. Pre-acquisition, TKG was attractive because it was essentially "free" for vSphere customers (included in vSphere licensing) and cost-competitive for public cloud deployments.
Under Broadcom, TKG has been absorbed into Tanzu Platform. The standalone TKG product no longer exists as a separate purchase option. Instead:
The transition creates confusion: customers who previously licensed TKG expecting unlimited Kubernetes cluster deployments now face the reality that meaningful Tanzu capabilities require Tanzu Platform licensing. The vSphere with Tanzu supervisor cluster (included in VCF) is a single control plane with limited governance capabilities — it's not a replacement for the former TKG offering.
Tanzu Application Service is the new name for Pivotal Cloud Foundry (PCF) — a platform-as-a-service (PaaS) that abstracts infrastructure complexity and allows developers to push applications to a shared platform without managing containers or Kubernetes. Large financial services, insurance, and government organizations have historically built substantial production workloads on PCF.
Broadcom inherited 5,000+ production TAS deployments globally when it acquired VMware. Rather than deprecating TAS immediately (which would trigger mass migration costs and customer backlash), Broadcom has taken a slower strategic approach: maintain TAS at high cost, actively develop Tanzu Platform as the modern alternative, and provide migration tooling for customers ready to move.
TAS licensing is typically quoted on a per-instance basis (instances = app containers), with an annual subscription. Broadcom increased TAS pricing substantially post-acquisition — increases of 15–25% are common in renewal negotiations. This pricing escalation reflects Broadcom's intent to push existing TAS customers toward either: (1) accepting higher costs for legacy TAS, or (2) migrating to Tanzu Platform or cloud-native PaaS services (AWS Elastic Beanstalk, Azure App Service, Google Cloud Run).
For TAS customers, renewal negotiations now involve two competing forces: TAS renewal cost hikes (pushing toward migration) versus Tanzu Platform licensing cost and migration complexity (pushing toward staying on TAS). This creates negotiation leverage.
| Platform | Pricing Model | Typical Annual Cost (1000 instances) | Learning Curve | Vendor Lock-In Risk |
|---|---|---|---|---|
| Tanzu Application Service (TAS) | Per instance | $300K–$500K | Moderate (PCF skills transferable) | High (TAS-specific APIs) |
| Tanzu Platform on K8s | Per core + instance fees | $250K–$600K | High (Kubernetes learning) | Moderate (standard K8s portability) |
| AWS Elastic Beanstalk | Pay-as-you-go (compute) | $100K–$350K | Moderate | Moderate (AWS lock-in) |
| Open-Source Kubernetes + Rancher | Infrastructure only; per-cluster subscription | $50K–$150K | High | Low (portable) |
This is the critical question that drives pricing confusion. VCF (all editions) includes vSphere with Tanzu capabilities, which provides:
What VCF does NOT include:
Many customers have assumed that vSphere with Tanzu represents full Tanzu Platform capabilities included in VCF. This assumption has led to significant surprise during contract negotiations when Broadcom clarifies that Tanzu Platform capabilities beyond the vSphere with Tanzu supervisor cluster require additional subscription.
Customers who believed Tanzu Kubernetes Grid was "included in vSphere" licensing may discover that full Tanzu capabilities require Tanzu Platform licensing as a separate subscription. vSphere with Tanzu (included in VCF) provides a single supervisor cluster with limited governance — not the full TKG experience from pre-acquisition versions.
Tanzu Platform uses per-core subscription pricing, aligned to your infrastructure core count. This creates several important considerations:
The core value proposition of Tanzu Platform is operational simplicity: it abstracts Kubernetes complexity and provides enterprise governance out of the box. But this comes at a cost. For many organizations, the Tanzu Platform per-core subscription fee represents a significant premium over open-source Kubernetes plus commercial support.
| Capability | Tanzu Platform | Upstream K8s + Rancher | OpenShift (Red Hat) |
|---|---|---|---|
| Base licensing cost (100 cores) | $36K–$96K/year | $5K–$20K/year | $40K–$120K/year |
| Kubernetes cluster provisioning | Yes (automated) | Yes (Rancher) | Yes (automated) |
| Multi-cluster governance & policy | Yes | Partial (Rancher) | Yes |
| Service mesh integration | Yes (Istio) | DIY or third-party | Yes (Istio) |
| Professional support | Included | Optional third-party | Included |
| Vendor lock-in | Moderate (Tanzu-specific features) | Low (standard K8s) | Moderate (RHEL, OIDC) |
| Public cloud support | AWS, Azure, GCP native | All clouds | AWS, Azure native |
Tanzu Platform costs 5–10x more than open-source Kubernetes with Rancher, but provides substantially faster time-to-value for enterprises with complex governance requirements. The decision hinges on: (1) your team's Kubernetes expertise, (2) regulatory/compliance requirements, and (3) acceptable risk on operational incidents.
