Crushing Cloud Egress and Database Lock-In: The Economic Case for Solanica on VMware VKS

The tech industry is hitting a financial wall.
A decade ago, the promise of the public cloud was simple: trade capital expenses for operational agility. For stateless applications, that promise largely held up. But for stateful workloads - specifically production databases and AI data layers—the reality has turned into a compounding financial burden.
Between soaring managed database premiums, unpredictable IOPS pricing, and predatory data egress fees, enterprises are paying a steep "cloud database tax" just to give their developers a modern, automated experience.
It doesn't have to be this way. Organizations are realizing they don't need to migrate data to the public cloud just to get cloud-like automation. By pairing the Solanica Platform with VMware vSphere Kubernetes Service (VKS), infrastructure teams can now deploy a fully automated DBaaS on VMware infrastructure - combining public cloud agility with private cloud economics.
This joint framework is detailed in our deep-dive architecture guide, DBaaS on VKS, which was built and validated directly with Broadcom to ensure native compatibility with VKS, which is built into the VMware Cloud Foundation (VCF) platform as a CNCF-certified Kubernetes distribution.
The Public Cloud Database Trap: Egress and Lock-In
When evaluating a cloud database alternative, IT leadership typically focuses on compute and storage. The real budget killers, however, hide in the operational margins:
- Growth of Cloud Egress Costs: The moment your database needs to talk to an on-premises analytics tool, a legacy core system, or a secondary data center, the public cloud bills skyrocket. Managed database services charge a premium for data movement, making it cost-prohibitive to scale data-heavy applications.
- Database Vendor Lock-In: Proprietary cloud database APIs are designed to keep you trapped. Once your operational runbooks, backup strategies, and application code are deeply tied to a specific cloud vendor’s ecosystem, migrating away becomes a multi-million-dollar architectural nightmare.
To avoid cloud database lock-in and reduce cloud egress fees, teams are shifting toward a Kubernetes database platform using VKS in their private cloud. This allows them to run open-source databases with the exact same automated workflows found in the public cloud, but entirely within their own perimeter. It also ensures they keep their data private and secure.
Why Run Solanica Platform on VMware VKS?
The architecture is built on a simple premise: Keep your hardware, get the cloud user experience. Instead of treating your private infrastructure as legacy hardware, running Solanica on VMware VKS turns your existing VMware infrastructure into a cloud-native database platform
1. Maximize Existing Hardware ROI
You’ve already invested heavily in your vSphere footprint. Moving to a public cloud managed database means paying a massive markup on infrastructure you already own. Solanica installs directly on your VMWare VKS clusters, allowing you to maximize the utilization of your existing hardware investments with zero infrastructure migration required.
2. Operational Efficiency at Scale
The traditional alternative to the public cloud was manual on-premises management - an approach that requires an army of specialized DBAs to handle replication, patching, and backups. Solanica bridges this gap. It acts as an automated orchestration layer, allowing a single infrastructure administrator to safely manage hundreds of data services - including PostgreSQL, MySQL, and MongoDB instances, and many more, all on VMWare VKS - via a unified UI or API.
3. A True Open Alternative to AWS RDS
When comparing Solanica Platform on VMware VKS vs RDS vs Azure Database, the core differentiator is freedom. Solanica uses the open-source power of OpenEverest as its engine. Because it runs on native Kubernetes, your configurations, automated backup policies, and operational workflows are fully portable. If you choose to run Solanica Platform on VMware VKS today and move a workload to bare metal or a sovereign cloud tomorrow, your database platform moves with you. You finally escape cloud vendor lock-in.
Turning Infrastructure into a Competitive Advantage
Consider a typical financial services institution or highly regulated manufacturer. They need to spin up isolated, multi-tenant databases for a new fleet of digital applications and modern AI initiatives.
If they choose the public cloud, they face strict compliance hurdles, high latency to their core on-prem data warehouses, and compounding monthly bills.
By deploying an open source DBaaS on VMware VKS using Solanica, the outcome changes entirely:
- The Developers get immediate self-service provisioning, automated point-in-time recovery (PITR), and built-in monitoring.
- The Compliance Team ensures that sensitive data never leaves the physical security of the private cloud.
- The CFO sees an immediate 60%+ reduction in database TCO by wiping out public cloud premiums and data egress fees completely.
Behind the Scenes: How It Works
Solanica integrates cleanly with your existing VMware stack, utilizing vSAN CSI for high-performance enterprise storage, NSX for secure networking, and vCenter for compute management. Beyond traditional relational engines, the combined architecture supports your entire modern application ecosystem—extending from multi-model caches to analytical engines and private AI vector stores.

Deploy in 3 Commands
To prove how straightforward the platform is, you can deploy the underlying engine directly to an existing VKS cluster in under ten minutes:
# 1. Authenticate into your VKS cluster
$ kubectl vsphere login --server=vcenter.corp.local --vks-cluster-name=prod-db
# 2. Add the secure Helm repository
$ helm repo add openeverest https://openeverest.github.io/helm-charts/
$ helm repo update
# 3. Install the orchestration layer
$ helm install everest openeverest/openeverest \
--namespace everest-system \
--create-namespace
# ✓ Operational on VMware vSphere Kubernetes Service
# ✓ Automated storage via vSAN, networking via NSX
# ✓ Ready to provision enterprise databases instantlyTake Control of Your Database Economics
Agility should not come at the expense of your financial bottom line or architectural freedom. Running the Solanica Enterprise Platform on VMware VKS gives your engineering teams the modern VMware VKS managed database experience they demand, while preserving the cost efficiency, security, and control of your private cloud infrastructure.
