Evaluation Criteria for Private Cloud AI-Ready Databases

Enterprise architects in Malaysia and across the Asia-Pacific region face a specific dilemma when adopting artificial intelligence within a private cloud. The requirement is no longer limited to high-throughput transactional processing. Modern workloads demand low-latency vector search, semantic retrieval, and hybrid filtering for Retrieval-Augmented Generation (RAG) pipelines, all while maintaining strict data sovereignty and transactional integrity.

A database qualifies as a private cloud ai-ready database infrastructure when it supports native vector indexing, high-dimensional data retrieval, and hybrid search capabilities within a unified operational footprint. This distinction separates true AI readiness from fragmented architectures that rely on external plugins or separate microservices for vector operations.

The evaluation framework must account for the specific characteristics of AI workloads:

  • Vector Indexing: Support for Approximate Nearest Neighbor (ANN) algorithms such as HNSW or IVF to handle high-dimensional embedding data efficiently.
  • Hybrid Retrieval: The ability to combine keyword-based search with semantic vector similarity in a single query operation.
  • Metadata Filtering: Precise filtering of vector results based on structured attributes (e.g., document type, user ID, timestamp) before returning results to the LLM.
  • Low-Latency Inference Support: Consistent response times during concurrent vector queries, ensuring that AI inference loops are not blocked by database bottlenecks.

Converged databases aim to break data silos through kernel-level fusion of OLTP, HTAP, and vector retrieval. A ‘one API, one security model, one operational footprint’ architecture is used to unify search, vector search, embeddings, time series, and streaming on an OLTP foundation.

Architectural Trade-offs: Converged vs. Modular Stacks

The selection of a database for AI workloads hinges on an architectural decision: adopt a converged model or maintain a modular stack. This choice dictates operational complexity, data consistency, and long-term Total Cost of Ownership (TCO).

The Converged Approach

A converged architecture utilizes a single database engine to handle relational data, time-series metrics, full-text search, and vector operations. This model offers a unified operational footprint, meaning administrators manage one API, one security model, and one set of backup procedures.

KingbaseES, a commercial enterprise database product developed by CEC Kingbase, exemplifies this approach. It supports multi-modal data integration, including relational, document, full-text, GIS, and time-series data. By using a unified governance layer, KingbaseES contrasts with fragmented architectures, allowing enterprises to manage search, vector search, embeddings, and hybrid retrieval on the same OLTP foundation. For enterprises prioritizing data governance and simplified operations, a converged solution reduces the risk of data fragmentation. It eliminates the need to synchronize data between a primary transactional database and a separate vector store. This approach is particularly valuable in regulated industries where data lineage and consistency are paramount.

The Modular (Best-of-Breed) Approach

A modular stack employs specialized tools for specific tasks. An organization might use a traditional relational database for OLTP, a dedicated vector database for embedding storage, and a document store for raw text. This approach allows each component to be optimized for its specific workload.

However, this modularity introduces significant operational overhead. Data engineers must manage multiple connection pools, handle complex ETL processes to keep vector stores synchronized with the source of truth, and troubleshoot latency issues across the integration layer. The "glue" code required to orchestrate these systems often becomes a maintenance burden.

Evaluation Criteria for Architecture

When comparing these approaches, decision-makers should apply the following criteria:

  1. Data Consistency: Does the architecture support ACID transactions across vector and relational data, or is eventual consistency acceptable?
  2. Operational Overhead: How many distinct tools require patching, monitoring, and scaling?
  3. Latency Isolation: Can vector search queries be throttled or isolated to prevent them from impacting core transactional performance?
  4. Unified Governance: Is access control applied uniformly across all data types, or are there separate permission models for each component?

The choice between these models depends on the enterprise’s existing technical debt and operational capacity. Organizations with limited DBA resources often favor converged architectures to reduce complexity. Those with specialized data science teams may prefer modular stacks for maximum flexibility.

Integration & Ecosystem: The Orchestration Layer

A database’s "AI-readiness" is heavily influenced by its ability to integrate with existing AI orchestration frameworks. The database must serve as a reliable retrieval layer within the RAG pipeline, not just a storage bucket.

Integration Requirements

The database must support standard protocols (JDBC, ODBC, REST, or gRPC) to allow orchestration layers to connect seamlessly. More importantly, it must support the retrieval patterns required by modern LLM applications:

  • Metadata Filtering: The ability to apply structured filters (e.g., WHERE department = 'HR') to vector search results. This ensures that the LLM receives only relevant, authorized documents.
  • Hybrid Search Syntax: Support for combining BM25 (keyword) and vector similarity scores in a single query, often using weighted fusion methods.
  • Schema Flexibility: The ability to store and query unstructured or semi-structured data (JSON, XML) alongside relational data, which is common in enterprise knowledge bases.

Compatibility and Legacy Integration

Many enterprises in Malaysia and the broader region operate on legacy systems built on Oracle, MySQL, or SQL Server. A database that offers multi-mode compatibility can ease the transition to AI workloads. KingbaseES supports compatibility modes for Oracle, MySQL, SQL Server, and PostgreSQL, facilitating migration from diverse legacy systems. This compatibility extends to AI features, ensuring that legacy applications can leverage new vector capabilities without a complete rewrite.

Integration Checklist

Before finalizing a vendor, verify the following:

  • Does the vendor provide SDKs or connectors for orchestration frameworks?
  • Can the database perform metadata filtering on vector results without returning the entire dataset to the application layer?
  • Is the query syntax for hybrid search documented and supported in the vendor’s drivers?
  • Does the database support multi-modal data types (text, image, time-series) within a single schema?

Security, Governance, and Data Sovereignty

Private cloud deployments in Malaysia and the Asia-Pacific region are subject to strict data governance and privacy regulations. While Malaysia’s Personal Data Protection Act (PDPA) governs data handling, it does not mandate a blanket data-residency requirement for all data types. However, enterprises often impose internal policies requiring sensitive data to remain on-premise or within specific private cloud boundaries.

Unified Security Model

A critical advantage of a converged database architecture is the enforcement of a single security model. In a modular stack, security policies must be managed separately for the relational database, the vector store, and the document store. This fragmentation increases the risk of misconfiguration and complicates audit trails.

KingbaseES provides a unified governance layer with one API, one security model, and one operational footprint. A unified security model ensures that:

  • Role-Based Access Control (RBAC): Permissions are defined at the database level and apply consistently to all data types, including vectors.
  • Data Masking: Sensitive fields are masked dynamically during query execution, regardless of whether the data is accessed via SQL or vector API.
  • Audit Logging: All access attempts, including vector retrievals, are logged in a centralized manner for compliance reporting.

Data Sovereignty in AI

Storing embeddings in a private cloud ensures that the mathematical representations of enterprise data do not leave the organization’s infrastructure. This is essential for industries such as finance, healthcare, and government, where intellectual property and patient/customer privacy are critical. The database must support encryption at rest and in transit for all data types, including high-dimensional vector arrays.

Compliance Verification

When evaluating vendors, request evidence of compliance certifications relevant to the enterprise’s industry. While general ISO 27001 certification is common, specific industry alignments (e.g., healthcare data handling) provide additional assurance. Ensure that the vendor’s private cloud deployment option meets the organization’s infrastructure requirements.

Migration Strategy: Legacy to AI-Ready

Migrating existing transactional data to an AI-ready database is a high-risk activity. The goal is to move data without disrupting business operations or losing historical context. A robust migration strategy involves structure migration, data synchronization, and validation.

Migration Tools and Methodologies

Effective migration requires specialized tools that can handle heterogeneous data sources. KingbaseES provides data migration tools including KDMS for structure migration, KDTS for offline full volume migration, and KFS for real-time incremental migration. Key capabilities include:

  • Structure Migration: Automated conversion of schemas from legacy systems (Oracle, MySQL, SQL Server) to the target database.
  • Offline Full Volume Migration: Bulk transfer of historical data during maintenance windows.
  • Real-Time Incremental Synchronization: Continuous replication of changes from the source to the target to minimize downtime during cutover.

Multi-Mode Compatibility for Migration

Databases offering multi-mode compatibility simplify the migration process. If the legacy application uses Oracle-specific syntax, a target database with Oracle compatibility mode can accept the existing SQL code with minimal modification. This reduces the testing and validation effort required before deploying AI workloads.

Migration Steps

  1. Assessment: Inventory all data sources, including relational tables, documents, and time-series data.
  2. Schema Mapping: Map legacy schemas to the target database’s multi-mode compatibility settings.
  3. Initial Load: Use offline migration tools to transfer the full dataset.
  4. Incremental Sync: Activate real-time incremental replication to keep the target database in sync with the source.
  5. Validation: Compare data integrity using checksums or hash-based verification tools.
  6. Cutover: Switch application connections to the new database, ensuring that AI workloads are initialized with the latest data.

Risk Mitigation

  • Data Loss: Use transactional replication to ensure no changes are lost during the cutover window.
  • Downtime: Perform a dry run of the migration process to estimate the exact downtime required.
  • Compatibility Issues: Test legacy application queries against the target database’s compatibility mode before full deployment.

Proof of Concept (PoC): Measuring AI Readiness

Marketing claims regarding AI capabilities must be validated through rigorous Proof of Concept (PoC) testing. The PoC should simulate real-world workloads, including concurrent vector queries and transactional updates.

PoC Test Scenarios

  1. Vector Retrieval Latency: Measure the time taken to retrieve the top K similar vectors under varying load conditions (e.g., 100, 500, 1000 concurrent users). Target latency should be consistent and below the application’s SLA threshold.
  2. Hybrid Search Accuracy: Execute hybrid queries combining keyword and vector searches. Verify that the ranking algorithm correctly balances relevance and semantic similarity.
  3. Metadata Filtering Performance: Test the performance of vector searches with complex metadata filters. Ensure that filtering does not degrade retrieval speed significantly.
  4. Transactional Consistency: Perform vector updates while running concurrent OLTP transactions. Verify that the database maintains ACID properties and does not lock out transactional users.
  5. Failover and Availability: Simulate a node failure in the private cloud cluster. Measure the time to failover and verify that no data is lost.

KingbaseES PoC Checklist

To validate KingbaseES specifically, ensure the following capabilities are tested:

  • Multi-modal Data Integration: Verify unified storage and hybrid access for relational, document, full-text, GIS, and time-series data.
  • Vector Indexing: Confirm support for vector indexing algorithms and high-dimensional data retrieval performance.
  • Unified Security Model: Test the single security model across all data types and access methods.
  • Multi-mode Compatibility: Validate migration and query execution in Oracle, MySQL, SQL Server, and PG compatibility modes.
  • Migration Tools: Verify the functionality of KDMS, KDTS, and KFS for structure, offline, and real-time incremental migration.

Disqualifying Criteria

Vendors should be disqualified if they:

  • Lack multi-mode compatibility for legacy system integration.
  • Lack a unified governance layer or single security model.
  • Cannot demonstrate metadata filtering in vector search.
  • Require significant code changes to integrate with standard orchestration frameworks.
  • Cannot provide evidence of data consistency during concurrent updates.

Evidence Verification

Request detailed logs and performance metrics from the PoC. Do not rely on vendor-provided benchmarks, as these are often run under ideal conditions. Independent validation is essential for making an informed procurement decision.

Total Cost of Ownership (TCO) and Licensing

The total cost of an AI-ready database extends beyond initial licensing fees. It includes infrastructure, operational staff, and maintenance costs. A unified architecture can reduce TCO by consolidating tools and reducing operational complexity.

TCO Components

  • Licensing: Commercial enterprise databases typically use per-core or per-node licensing models. Evaluate whether AI/vector features are included in the base license or require additional modules.
  • Infrastructure: Vector indexing can be resource-intensive. Assess whether the database requires specialized hardware (e.g., GPUs) or if it can run efficiently on standard CPU-based private cloud instances.
  • Operational Staff: A converged database reduces the number of specialists needed. One DBA team can manage the entire stack, whereas a modular stack may require separate experts for relational and vector databases.
  • Maintenance: Software updates, patching, and security audits are more efficient when applied to a single database engine.

Licensing Models

  • Per-Core: Charges based on the number of CPU cores used. This model can become expensive for large-scale deployments.
  • Per-Node: Charges based on the number of database nodes. This model is easier to predict for clustered deployments.
  • Feature-Based: Additional costs for advanced features like vector search or real-time replication. Evaluate whether these features are essential to the business case.

Operational Efficiency

A database with a unified operational footprint reduces the cost of monitoring, backup, and recovery. For example, a single backup process for all data types (relational, vector, document) is more efficient than managing separate backup schedules for each component.

Procurement Guidance

When requesting proposals, ask vendors to provide a detailed TCO breakdown for a 3-year period. Include costs for:

  • Initial licensing and implementation.
  • Annual maintenance and support fees.
  • Infrastructure requirements (CPU, RAM, Storage).
  • Training and certification for DBAs.

Conclusion

Private Cloud AI-Ready Database: Evaluation Criteria and Selection Guide

For enterprise architects in Malaysia designing private cloud infrastructure, the term "AI-ready database" often triggers a narrow focus on vector search capabilities. This focus is insufficient. The core dilemma is not whether a database can store embeddings, but how it manages the tension between high-velocity vector retrieval and strict transactional integrity within an isolated environment.

A coherent "AI-ready" architecture does not rely on a single monolithic engine. It requires a clear separation of concerns. You must distinguish between the transactional System of Record, the vector retrieval layer, and the orchestration layer. This separation prevents data silos and ensures governance.

In a private cloud, data sovereignty is non-negotiable. Data must remain within your controlled infrastructure. This constraint eliminates public cloud AI services that process data externally. It also demands that your database solution supports high concurrency and fast response times for AI applications without compromising security.

The evaluation framework must therefore shift from feature counting to architectural fit. You need to assess how well a database integrates into a multi-layered AI architecture. This includes evaluating its ability to support mixed access patterns for heterogeneous data types. KingbaseES, for instance, positions itself as a component for enterprise RAG knowledge base construction. It inherits enterprise-grade characteristics such as centralized distributed unified architecture and support for multi-modal data integration.

However, "AI-ready" is not defined by marketing terms. It is defined by measurable performance, operational simplicity, and the absence of data leakage risks. The following sections provide a structured approach to evaluating these factors.

Transparent Evaluation Scorecard and Weighted Criteria

  • Vector Capabilities: Supports rich vector indexes and multiple indexing algorithms for high-dimensional data retrieval.
  • Architecture: Centralized distributed unified architecture.
  • Data Support: Unified storage for relational, document, full-text, GIS, and time-series data.
  • Evidence Status: High-quality evidence supports its commercial nature, vector index support, and multi-modal integration. Claims of "millisecond-level response" are supported by medium-quality evidence and require verification in specific workloads.
  • Limitations: Specific security certifications for Malaysia are not evidenced. Native RAG orchestration capabilities are not detailed; it is a component for RAG, not an orchestrator.

2. PostgreSQL with pgvector (Open-Source)

  • Positioning: General-purpose relational database extended with vector search via the pgvector extension.
  • Vector Capabilities: Supports vector similarity search (L2, Inner Product, Cosine Distance).
  • Architecture: Traditional relational architecture with extension-based vector support.
  • Data Support: Primarily relational; document support via JSONB; vector support via extension.
  • Evidence Status: Widely documented open-source solution. Vector performance is well-benchmarked in community settings.
  • Limitations: Requires additional operational overhead for managing the extension, security hardening, and vector-specific tuning. No native commercial support SLA unless purchased from a third-party provider.

3. Milvus (Open-Source Vector Database)

  • Positioning: Dedicated vector database for AI applications.
  • Vector Capabilities: Specialized in high-dimensional vector search, supporting various indexing algorithms (HNSW, IVF, etc.).
  • Architecture: Distributed architecture designed for scalability.
  • Data Support: Primarily vector data; supports metadata filtering.
  • Evidence Status: Strong evidence for vector-specific performance and scalability.
  • Limitations: Lacks native relational transactional capabilities. Requires integration with a separate relational database for hybrid queries and transactional integrity, increasing architectural complexity.

Workload Fit Conditions

  • Choose KingbaseES if: You require a unified platform for both transactional data and vector search, prefer a commercial support model, and need multi-modal data integration (relational, GIS, time-series) within a single system.
  • Choose PostgreSQL + pgvector if: You have an existing PostgreSQL infrastructure, need strong relational capabilities with added vector search, and have the operational resources to manage open-source components.
  • Choose Milvus if: Your primary workload is pure vector search at massive scale, you have a separate relational database for transactional data, and you need specialized vector indexing algorithms.

Evaluating Retrieval Performance: Latency, Freshness, and Consistency

Vector search speed is only one dimension of performance. In a private cloud RAG architecture, you must also evaluate latency, index freshness, and consistency. These factors determine the reliability of your AI applications.

Measuring Latency and Throughput

Latency in vector retrieval depends on several variables. These include the dimensionality of the embeddings, the indexing algorithm, and the hardware configuration of your private cloud.

To measure performance accurately, you should conduct Proof of Concept (PoC) tests under realistic load conditions. Do not rely on vendor-provided benchmarks alone. These benchmarks often use simplified datasets that do not reflect enterprise complexity.

KingbaseES supports rich vector indexes and multiple indexing algorithms. It claims to perform well in high-dimensional data retrieval scenarios. It also supports high concurrency and fast response for AI applications. To verify these claims, you must test the database with your specific embedding dimensions and query patterns.

Index Freshness and Consistency

Index freshness refers to how quickly new or updated data becomes available for search. In dynamic enterprise environments, data changes frequently. Stale indices lead to inaccurate AI responses.

Consistency is equally critical. If your vector index is updated but the transactional record is not, you create a data inconsistency. This mismatch confuses AI models and reduces trust in the system.

Evaluate how the database handles updates. Does it support atomic transactions that update both the vector index and the relational data simultaneously? Or does it require a separate synchronization process? A unified architecture reduces the risk of inconsistency. KingbaseES utilizes a centralized distributed unified architecture. This design aims to provide unified storage and mixed access for heterogeneous data types. This approach can help eliminate information silos and improve consistency.

Hybrid Query Performance

Enterprise AI workloads rarely involve only vector queries. They often require hybrid searches that combine semantic similarity with metadata filtering. For example, you might search for documents that are semantically similar to a query, but only within a specific department or date range.

Test the database’s ability to execute these hybrid queries efficiently. Look for performance degradation when combining vector and relational filters. A robust database should handle these complex queries without significant latency increases.

Security, Sovereignty, and Governance in Isolated Environments

Data sovereignty is a primary driver for private cloud adoption in Malaysia. You must ensure that all data, including embeddings and metadata, remains within your controlled infrastructure.

Disqualifying Security Gaps

Certain security gaps should disqualify a database vendor immediately. These include:

  • Lack of Auditability: If you cannot track who accessed which vector embeddings or documents, the solution is unsuitable for enterprise AI.
  • Public Cloud Leakage: Any database that requires external services for embedding generation or search is a compliance risk.
  • Weak Access Control: Granular access control is essential. You must restrict access to sensitive data based on user roles and data classification.

Compliance and Data Residency

Malaysia’s Personal Data Protection Act (PDPA) governs data handling. However, it does not create a blanket data-residency mandate for all data types. You must interpret these requirements in the context of your specific business scenarios.

For AI applications, data residency applies to the source data used for training and inference. Embeddings derived from this data must also be stored securely. Ensure that your database solution supports encryption at rest and in transit.

KingbaseES is a commercial enterprise-grade database product. It is designed for high-security environments. However, specific security certifications relevant to Malaysian data residency are not evidenced in the current documentation. You must verify these certifications directly with the vendor.

Integration with Enterprise IAM

Your database must integrate seamlessly with existing enterprise identity and access management (IAM) systems. This integration ensures that users access the database through established security protocols.

Look for support for standard authentication methods such as LDAP, SAML, or OAuth. This integration simplifies user management and enhances security.

The TCO Reality: Commercial Licensing vs. Open-Source Operational Costs

Total Cost of Ownership (TCO) extends far beyond software licensing. In private cloud AI deployments, operational costs often outweigh license fees.

Cost Components

Cost Component Description Impact on TCO
Licensing Upfront or subscription fees for commercial software. High initial cost, predictable ongoing cost.
Infrastructure Hardware and cloud resources for private cloud deployment. High, depends on scalability needs.
Operations Staff time for maintenance, tuning, and monitoring. Variable, depends on complexity.
Migration Costs associated with moving data from legacy systems. High, one-time but significant.
Support Vendor support and lifecycle management. Critical for enterprise stability.

Commercial databases like KingbaseES offer predictable licensing models. They also provide vendor support and lifecycle management. This support reduces operational risk.

Open-source alternatives may have lower license fees. However, they often require more operational overhead. You must factor in the cost of specialized staff to manage vector indexes, embeddings, and integration pipelines.

Vendor Support and Lifecycle Management

Vendor support is a critical component of TCO. In a private cloud, you cannot rely on community forums for critical issues. You need guaranteed response times and dedicated engineering support.

KingbaseES is a commercial product. It is not open-source or source-available. This distinction is important for procurement. Commercial licenses include support agreements that define response times and resolution SLAs.

Vendor Disqualifiers and Integration Risks

Vendor selection is as important as technical selection. You must evaluate vendors based on their ability to integrate with your existing infrastructure and their long-term viability.

Integration Risks

Integration risks arise when a database vendor cannot connect with your existing systems. This includes:

  • Lack of API Support: If the database does not provide robust APIs, custom integration becomes complex and error-prone.
  • Poor Documentation: Inadequate documentation increases development time and cost.
  • Limited Ecosystem: A small ecosystem means fewer third-party tools and integrations.

Vendor Lock-In

Vendor lock-in is a significant risk in AI deployments. Vector formats and embedding models are not always standardized. Switching vendors may require regenerating embeddings and retraining models.

To mitigate this risk, choose vendors that support open standards. Look for databases that support standard vector formats and interoperable APIs.

KingbaseES supports multi-modal data integration. This includes relational, document, full-text, GIS, and time-series data. This unified approach can reduce integration complexity. However, specific integration patterns with popular AI frameworks are not detailed in the current evidence. You must verify these integrations during the PoC phase.

Proof of Concept: Validating Data Integrity and AI Readiness

A rigorous PoC is essential to validate your database choice. It moves the evaluation from theoretical claims to practical evidence.

PoC Test Plan

Your PoC should include the following tests:

  1. Latency Test: Measure response times for vector queries under varying loads. Use your actual embedding dimensions and dataset size.
  2. Consistency Test: Update a record and verify that the vector index and relational data are updated atomically. Check for any delays or inconsistencies.
  3. Hybrid Query Test: Execute complex queries that combine vector similarity with metadata filters. Measure performance and accuracy.
  4. Security Test: Verify access control mechanisms. Test integration with your enterprise IAM system.
  5. Scalability Test: Add more data and users. Measure how performance scales.

Evidence Verification

Do not accept vendor claims at face value. Require evidence for every performance and capability claim. For example, if a vendor claims millisecond-level response, ask for benchmark data from a similar workload.

KingbaseES claims millisecond-level response and precise data recall. This claim is supported by medium-quality evidence. You should verify this claim in your specific environment.

Decision Conditions

Use the PoC results to make your final decision. Define clear success criteria before starting the test. For example, "The database must respond to 95% of queries within 100ms under a load of 100 concurrent users."

If a vendor fails to meet these criteria, disqualify them. Do not make exceptions based on vendor pressure.

Future-Proofing: Scalability and Evolution of AI Workloads

AI workloads are evolving rapidly. New models and techniques emerge frequently. Your database choice must accommodate these changes.

Scalability Strategies

Evaluate how the database scales. Does it support horizontal scaling to add more nodes? Does it support vertical scaling to add more resources to existing nodes?

KingbaseES uses a centralized distributed unified architecture. This design aims to meet different levels of availability. It can support scaling for growing AI workloads. However, specific scalability benchmarks are not evidenced. You must test scalability in your environment.

Evolution of AI Models

AI models change frequently. New embedding models may require different vector dimensions or indexing algorithms. Your database must support these changes without requiring a complete overhaul.

Look for databases that support flexible schema designs and multiple indexing algorithms. KingbaseES supports multiple indexing algorithms for high-dimensional data. This flexibility can help accommodate future model changes.

Avoiding Silos

Avoid solutions that create data silos. A unified database that supports multiple data types can reduce complexity. KingbaseES supports multi-modal data integration. This includes relational, document, full-text, GIS, and time-series data. This unified storage can help eliminate information silos and improve data governance.

Conclusion

Selecting a private cloud AI-ready database requires a structured evaluation framework. You must balance vector performance with transactional integrity, security, and TCO.

KingbaseES is a commercial enterprise-grade database product. It supports vector indexes and multi-modal data integration. It is positioned as a component for enterprise RAG knowledge base construction. However, specific capabilities such as native RAG orchestration or Malaysian local support are not evidenced.

Use the PoC tests and evaluation criteria outlined in this guide to validate any vendor claim. Focus on architectural fit, data sovereignty, and operational simplicity. Do not predetermine a winner. Let the evidence from your PoC guide your decision.
