Solution Sizing Framework

Workload Assessment Matrix

Workload Type | Data Volume | Queries/Day | Users | SLA Req | Arch Pattern
─────────────────────────────────────────────────────────────────────────
RAG System    | 100K docs   | 10K         | 50    | 99.9%   | Active-Active
Database      | 50GB        | 100K        | 500   | 99.95%  | HA Cluster
Analytics     | 500GB+      | 1K batch    | 20    | 99%     | Hub-Spoke
Monitoring    | 1TB/month   | Streaming   | 10    | 95%     | Centralized
Cache Layer   | 10GB        | 1M ops/sec  | 100   | 99.9%   | Local Replica

Hardware Sizing Calculator

STEP 1: Determine Workload Requirements
─────────────────────────────────────────
Input: Concurrent users, queries/sec, data volume
Calculate: Peak load, memory needed, storage

Example:
  - 100 concurrent users
  - 500 queries/second peak
  - 1 million document vectors
  - Average response latency: <200ms

STEP 2: Map to Azure Local Hardware
─────────────────────────────────────────
Input: Workload requirements
Output: Recommended cluster configuration

Calculation:
  LLM Service: 100 concurrent × 500 QPS = 5 GPU nodes (16GB VRAM each)
  Vector DB: 1M vectors × 2KB per vector = ~2GB memory (1 node + replica)
  Total: 5 GPU nodes + 2 data nodes + 2 management = 9 nodes

STEP 3: Validate Against Hardware Constraints
─────────────────────────────────────────────
CPU: 9 nodes × 32 cores = 288 cores ✓
Memory: 9 nodes × 384GB = 3.5TB ✓
Storage: 50TB total available ✓
Network: 25Gbps fabric ✓

STEP 4: Add Redundancy & Growth Buffer
──────────────────────────────────────
Redundancy: 2x (HA replicas)
Growth buffer: 30% (capacity planning)
Year 1: 11 nodes
Year 2: 14 nodes
Year 3: 18 nodes

Sizing Questions by Component

LLM Inference Sizing

Question: What's your concurrent user requirement?
- Light: <50 users → Single T4 GPU (16GB)
- Medium: 50-500 users → 3-5 T4 GPUs
- Heavy: 500-5000 users → 8-16 A100 GPUs
- Enterprise: 5000+ users → Multi-node GPU cluster

Question: What inference performance is needed?
- Response latency <300ms → Quantized model (INT4) + batching
- Response latency <500ms → Quantized model (INT8)
- Response latency <1s → Non-quantized model
- Batch processing → Throughput optimization (larger batches)

Recommendation: Mistral 7B INT4 on T4 GPU serves 500 QPS @ 200ms latency

Vector Database Sizing

Question: How many documents will you index?
- <1M vectors → Single-node Chroma or FAISS
- 1-10M vectors → Single-node Qdrant or Weaviate
- 10-100M vectors → Multi-node Milvus with sharding
- >100M vectors → Distributed deployment with replication

Question: What's your QPS requirement?
- <100 QPS → Single-node (standard config)
- 100-1000 QPS → Replicated single-node
- 1000-10000 QPS → Multi-shard with load balancing
- >10000 QPS → Enterprise multi-region deployment

Recommendation: 1M vectors + 500 QPS = 2-node Qdrant with replication

Storage Sizing

Calculation:
  Embeddings: 1M vectors × 1536 dims × 4 bytes (FP32) = ~6GB
             (or ~1.5GB with INT8 quantization)
  Cache layer: 10GB for hot data
  Backup: 3x storage for 3 copies
  Growth buffer: 30% for 12 months

  Total = (6GB + 10GB) × 3 × 1.3 = ~62GB minimum
  Recommended: 100GB SSD allocation

Common Objections & Responses

”We’re not ready for edge AI yet”

Root Concern: Risk, capability gap, timing misalignment

Effective Response:

"I understand the concern. Many of our customers started with a
proof of concept to validate readiness. We can:

1. Start with a limited POC (50 users, 1 workload)
2. Use our training and enablement to build your team's skills
3. Microsoft provides 24/7 support during implementation
4. We can phase deployment: 3-6 months to production, not 12+ months

Your competitors are already deploying edge AI. Starting a POC now
positions you to be ready when the business urgently needs it.
What if we scheduled a 2-week assessment to validate your readiness?"

“Cloud APIs are cheaper”

Root Concern: Misconception about TCO, concerns about long-term costs

Effective Response:

"Let's run the numbers together:

Cloud API approach:
- 100 million queries/year × 150 tokens avg
- 15 billion tokens/year × $0.00001 = $150K/year
- 5-year cost: $750K

Edge approach:
- Hardware: $200K (one-time)
- Operations & licenses: ~$426K/year
- 5-year cost: $2.33M

BUT you're comparing apples to oranges:
- Cloud APIs are stateless queries only (no integration, no context)
- Edge gives you proprietary data integration, full control, sovereignty
- At scale (>30M queries/year), edge is 40% cheaper per query

Plus: Sovereignty, data residency, compliance, low latency.

What's your expected query volume in year 1?"

“We can’t afford the hardware investment”

Root Concern: Budget constraints, capital allocation challenges

Effective Response:

"I hear you. Let's explore financing options:

1. Phased deployment: Start with 2-3 nodes, grow to full 9-node
   cluster over 18 months. Spreads capex across budgets.

2. Leasing model: Many partners offer hardware leasing at
   ~$15-20K/month vs. $170K upfront. Check your capex policy.

3. Shared infrastructure: Co-host with non-production workloads,
   development environments. Reduces initial hardware needs by 30-40%.

4. Partner co-investment: We have partner programs where innovation
   credits can offset hardware costs.

5. Hybrid approach: Start on-premises with smaller cluster, extend
   to cloud during peaks. Get benefits immediately.

What budget cycle are you working with, and would phased
deployment help you get approval?"

“We have concerns about security”

Root Concern: Data protection, compliance, operational security

Effective Response:

"Security is paramount. Here's our approach:

1. Data sovereignty: Keep all data on-premises, never transmitted to cloud
2. Encryption: AES-256 at rest, TLS 1.3 in transit
3. Access control: RBAC + MFA + audit logging
4. Compliance: Built-in GDPR, FedRAMP, HIPAA support
5. Monitoring: 24/7 threat detection and incident response
6. Supply chain: Trusted hardware partners, secure boot

Most customers find edge IMPROVES security because:
- No cloud data transfer
- Complete visibility and control
- Disconnected operation capability
- Local incident response

Let me show you our security architecture. What are your
specific compliance requirements?"

“We’re invested in [competitor] already”

Root Concern: Switching costs, existing relationships, integration concerns

Effective Response:

"I understand the existing investment. Azure can work alongside
existing systems:

1. Integration: Azure Arc connects servers from any cloud/platform
2. Hybrid: Run workloads on both Azure and your current platform
3. Migration: Phased migration path if desired (3-6 months typical)
4. Interoperability: APIs and standards-based (Kubernetes, etc.)

Many customers run hybrid environments:
- Critical workloads stay on existing platform
- New AI/edge workloads on Azure
- Shared management from Azure Arc

This gives you best of both without rip-and-replace risk.

What specific workloads are you considering for edge?
Would a hybrid approach work better for you?"
