AWS AgentCore vs LangChain vs Alibaba AgentLoop Compared

TL;DR: AWS AgentCore provides managed orchestration with Runtime hosting, LangChain offers application-level control with portable execution, and Alibaba AgentLoop delivers an opinionated production pattern. Choose AgentCore Harness for AWS-native managed loops, LangChain for framework flexibility across clouds, or AgentLoop when its workflow abstraction matches your architecture.

Key Takeaways

• AgentCore Harness manages the orchestration loop; Runtime hosts custom frameworks. Compare managed services against code ownership before choosing infrastructure.
• LangChain/LangGraph gives you the orchestration graph and state contract. Hosting, observability, and identity remain your responsibility.
• Alibaba AgentLoop documents a production pattern: intent routing, tool execution, memory integration, and monitoring. Implementation is your own code following their architecture.
• Gateway/MCP integration differs: AgentCore Gateway exposes APIs as MCP tools, LangChain uses client adapters, AgentLoop documents tool contracts without a managed gateway.
• Cost boundaries span different layers: AgentCore meters managed services, LangChain costs are hosting plus models, AgentLoop costs are your infrastructure plus any Alibaba Cloud services used.

What are AWS AgentCore, LangChain, and Alibaba AgentLoop?

Amazon Bedrock AgentCore (checked September 30, 2026) provides managed services for agent orchestration (Harness), custom framework hosting (Runtime), shared memory (Memory), tool gateways (Gateway), browser automation, and code execution. These services work independently or together. Harness owns the agent loop; Runtime hosts code you bring. Neither locks you into Bedrock models exclusively.

LangChain and LangGraph form an open-source framework for building agent applications. LangChain supplies model integrations, tools, and retrieval; LangGraph handles state machines and orchestration. You own the execution environment, state persistence, and operational contract. Optional managed services (LangSmith, LangGraph Cloud) are separate products.

Alibaba AgentLoop is an architectural pattern documented by Alibaba Cloud's AI team (1,064 GitHub stars as of September 30, 2026). The handbook describes a production agent lifecycle: intent understanding, tool selection, execution, memory integration, monitoring, and human-in-the-loop workflows. It prescribes abstractions and contracts rather than distributing a framework package.

The three-way comparison matters because organizations evaluating "managed versus code" often miss the third option: a documented production pattern with implementation flexibility.

How do these frameworks compare at a glance?

None of these choices eliminate your responsibility for authorization, evaluation, tool idempotency, or production validation.

What is the managed-versus-code decision really asking?

The question "managed or self-hosted" conflates three separate decisions:

1. Who owns the orchestration loop? (Managed Harness vs. your graph)
2. Where does the agent run? (AWS Runtime vs. your host vs. serverless)
3. What do you implement versus configure? (AgentCore services vs. LangChain code vs. AgentLoop contracts)

Decision 1: Orchestration ownership

AgentCore Harness is not "infrastructure" — it manages orchestration. Runtime is the hosting service. Conflating them obscures the actual decision.

Decision 2: Hosting and runtime environment

Harness runs managed; Runtime accepts containers. LangChain runs wherever you deploy it. AgentLoop is a set of contracts; hosting is your choice.

Decision 3: Build versus integrate

AgentCore gives you services; LangChain gives you libraries; AgentLoop gives you architecture. None is a complete solution out of the box.

When should you choose AWS AgentCore Harness?

AgentCore Harness manages the orchestration loop. Choose it when the managed behavior matches your workflow and AWS hosting is acceptable.

AgentCore Harness strengths

1. Managed orchestration and tool execution policy. Harness runs the agent loop, invokes tools, and applies configured guardrails. You don't implement the graph.
2. Integrated AWS services. Memory, Gateway, Browser, Code Interpreter are first-party integrations. Identity, networking, and observability use AWS constructs.
3. Built-in MCP Gateway. AgentCore Gateway exposes REST APIs, Lambda functions, and S3 as MCP tools. You configure endpoints; Gateway handles tool calling.
4. Regional managed runtime. AWS operates the execution environment. You configure, not deploy.
5. Native Bedrock integration. Harness works with all Bedrock models plus external models via Runtime hosting or API.

When Harness fits

• Your workflow maps to Harness's supported behaviors (tool calling, sequential or branching logic, memory integration)
• AWS is already your platform and service dependencies are acceptable
• You want AWS to operate the loop and address scaling, availability, and patching
• Tool policy (deny external writes during read-only tasks) aligns with Harness controls
• The team prefers configuration over orchestration code

When Harness doesn't fit

• You need custom state machines, conditional branching, or loop logic Harness doesn't expose
• Interrupt-and-resume with arbitrary approval workflows requires graph-level control
• Multi-cloud or on-premise hosting is required
• Service quotas, regional availability, or pricing don't meet requirements
• You want code ownership of the orchestration graph

Use Runtime instead of Harness when you bring your own framework. Harness and Runtime are not mutually exclusive — AgentCore is both services, not one.

When should you choose LangChain and LangGraph?

LangChain/LangGraph gives you the framework and leaves hosting, observability, and operations to you. Choose it when you need code-level control and portable execution.

LangChain/LangGraph strengths

1. You own the orchestration graph. LangGraph state machines are code. Conditional edges, loops, parallel execution, and custom logic are all explicit.
2. Interrupt and resume with persistence. `interrupt_before` halts execution at a node; state checkpointers (Postgres, Redis, etc.) persist the graph. Resume is an API call with the checkpoint ID.
3. 100+ model integrations. LangChain abstracts OpenAI, Anthropic, Bedrock, Gemini, local models, and more. Switching models is a configuration change, not a rewrite.
4. MCP client adapters. Connect to any MCP server; tools are discovered dynamically. No managed gateway required.
5. Portable execution. Run the same agent code on AWS, GCP, Azure, Kubernetes, or your laptop. Dependencies are Python packages, not cloud services.
6. Composable memory. Thread-level checkpointers persist conversation state; cross-thread stores hold facts. You choose backends and namespace logic.

When LangChain fits

• You need custom orchestration: parallel tool calls, conditional branching, retry loops, or workflow-specific state machines
• Human-in-the-loop approval gates with interrupt-resume are required
• Portable execution across clouds or on-premise is a priority
• You want framework flexibility without managed service dependencies
• LangSmith observability or LangGraph Cloud hosting are acceptable (both optional)
• The team has Python expertise and prefers owning the graph

When LangChain doesn't fit

• You want a managed loop and don't need custom state machines
• Operating hosting, scaling, observability, and state persistence is outside your scope
• AWS-native integrations (IAM, CloudWatch, S3, Bedrock) are a hard requirement
• The team lacks the expertise to implement and test orchestration code
• No one will maintain the graph as requirements evolve

LangChain is not "unmanaged AgentCore" — it's application code. The right comparison is LangChain on Runtime versus LangChain on your own host.

When should you choose Alibaba AgentLoop?

AgentLoop is a documented architectural pattern, not a service or framework package. Choose it when its abstractions fit and you're implementing from contracts.

AgentLoop pattern strengths

1. Production-proven workflow architecture. The handbook documents intent routing, tool execution, memory integration, and monitoring based on Alibaba's production agents.
2. No framework lock-in. AgentLoop is a set of interfaces and contracts. Implement with LangChain, your own code, or any framework.
3. Opinionated abstractions. Intent, Tool, Memory, Monitor, and Executor are defined. You build against clear contracts rather than inventing abstractions.
4. Multi-stage agent lifecycle. The pattern covers intent understanding, planning, execution, memory retrieval, result synthesis, and feedback. Each stage has documented inputs and outputs.
5. Monitoring and observability contracts. AgentLoop specifies what to instrument: intent classification accuracy, tool selection precision, execution latency, memory hit rate, user satisfaction.
6. Human-in-the-loop workflows. The pattern defines approval gates, confidence thresholds, and escalation paths. Implementation is your code.

When AgentLoop fits

• You're building from architectural contracts and prefer proven patterns over framework opinions
• The team will implement orchestration, memory, and tool layers
• You want flexibility in hosting, models, and infrastructure
• Alibaba Cloud services (if used) are acceptable
• You need a reference architecture for production agents and will adapt it
• No managed service or open-source framework fully matches requirements

When AgentLoop doesn't fit

• You want a managed service, not a pattern to implement
• The team lacks capacity to build orchestration, state machines, and memory systems
• You need framework code to start from, not contracts
• AWS or LangChain already solve the problem and introducing a third abstraction adds complexity
• The pattern's workflow stages don't match your agent's actual behavior

AgentLoop is not "Alibaba's AgentCore" — it's documentation, not a deployed service. Compare it against building your own architecture from scratch, not against managed offerings.

How do memory and state management compare?

Memory is a frequent source of confusion because "memory" conflates thread-level state, cross-session facts, and long-term knowledge.

AgentCore Memory

AgentCore Memory is a managed vector store for multi-session context. It persists facts, user preferences, and retrieved knowledge across conversations. Memory is separate from Harness's thread state.

When to use AgentCore Memory:

• Multi-session agents need to recall past interactions
• User preferences, learned facts, or context should survive beyond a single conversation
• AWS-managed vector storage with Bedrock integration is acceptable
• You want to configure memory, not implement a retrieval layer

Integration: Harness can query Memory during orchestration. Runtime agents access Memory via SDK. Memory is not required to use Harness.

LangChain checkpointers and stores

LangChain separates thread state (checkpointers) from cross-thread memory (custom stores).

Checkpointers persist the LangGraph state at each node. Postgres, Redis, SQLite, and in-memory checkpointers are built-in. Checkpointers enable interrupt-resume.

Cross-thread stores hold facts, summaries, or retrieved context that span conversations. You implement the store, query logic, and namespace. LangChain includes vector store integrations (Pinecone, Weaviate, Qdrant, pgvector).

When to use LangChain memory:

• You need portable state persistence across environments
• Interrupt-resume requires durable checkpoints
• Memory backend choice (Postgres, Redis, vector DB) is a requirement
• You want to control namespace, retention, and retrieval logic

Integration: Checkpointers are LangGraph configuration. Memory stores are tool calls or retrieval chains.

AgentLoop memory pattern

AgentLoop defines a Memory interface with store, retrieve, and update methods. The pattern specifies when to query memory (intent understanding, context enrichment, result synthesis) but not the implementation.

When to use AgentLoop memory:

• You're implementing the full AgentLoop pattern
• Memory backend (vector DB, graph DB, relational store) is an open decision
• You need multi-source memory: user facts, domain knowledge, interaction history
• Retrieval logic (semantic search, keyword match, graph traversal) is complex

Integration: Your implementation calls the Memory interface at documented workflow stages.

Memory comparison

Choose based on ownership preference: managed service, framework integration, or pattern implementation.

How do tool integration and MCP support compare?

Tool calling is central to agent utility, but "MCP support" means different things in each framework.

AgentCore Gateway

AgentCore Gateway exposes REST APIs, Lambda functions, S3 buckets, and databases as MCP tools. Gateway is a managed service that translates API definitions into MCP tool schemas, handles authentication, and routes calls.

Gateway workflow:

1. Register an API (OpenAPI spec), Lambda function (ARN), or S3 bucket with Gateway
2. Gateway generates MCP tool schema automatically
3. Harness or Runtime agents discover tools via Gateway
4. Agent calls tool; Gateway authenticates, invokes backend, returns result
5. Gateway logs calls and enforces policies

When Gateway fits:

• You have internal APIs that agents should discover as tools
• Managed MCP translation from OpenAPI/Lambda/S3 reduces integration effort
• AWS IAM and networking already secure your APIs
• Centralized tool governance (deny external writes, rate limits) is required

When Gateway doesn't fit:

• You need MCP servers for Git, Slack, databases, or other non-AWS integrations
• Tool calling logic requires middleware (caching, retries, transforms)
• Portable execution means Gateway isn't available in other clouds
• Gateway pricing or quotas are prohibitive

LangChain MCP adapters

LangChain provides MCP client adapters that connect to any MCP server. Tools are discovered dynamically; no translation layer required.

MCP workflow with LangChain:

1. Start MCP server (filesystem, GitHub, Postgres, Slack, etc.)
2. Connect agent to server via `MCPClient` adapter
3. Agent queries server for available tools
4. Agent calls tools; server executes and returns results
5. You instrument tool calls via LangSmith or custom telemetry

When LangChain MCP fits:

• You want to connect to existing MCP servers (not build a gateway)
• Tool calling logic lives in application code (retries, error handling, transforms)
• Portable execution means you can't depend on a managed gateway
• Multiple MCP servers need to be composed per agent task

When LangChain MCP doesn't fit:

• You want centralized tool governance without per-agent logic
• AWS-native API integration (Lambda, S3, Bedrock) is a priority
• No one will operate MCP servers
• Gateway already exposes the tools you need

AgentLoop tool pattern

AgentLoop defines a Tool interface with name, description, parameters, and execute methods. The pattern specifies tool selection logic (match intent to tool), execution (call with parsed args), and error handling (retry, fallback, escalation). MCP is not prescribed.

AgentLoop tool workflow:

1. Define tools per the Tool interface (your code)
2. Implement tool registry (discovery by intent)
3. Implement tool executor (invoke, timeout, retry)
4. Instrument tool calls (latency, errors, retries)
5. Optionally integrate MCP servers via adapter

When AgentLoop tools fit:

• You're implementing the full AgentLoop pattern
• Tool calling logic is complex (conditional retries, fallback chains, result validation)
• You want control over tool discovery, selection, and execution
• MCP is one integration option among many

When AgentLoop tools don't fit:

• You want a managed gateway or framework-provided MCP support
• Tool integration is straightforward and doesn't justify a custom abstraction
• Gateway or LangChain already solve the problem

Tool integration summary

Choose based on integration needs: managed gateway, framework adapters, or custom tool layer.

What are the cost models and pricing boundaries?

Cost structures differ because ownership differs.

AgentCore pricing

AgentCore meters managed services:

• Harness: Orchestration requests, tool invocations, memory queries
• Runtime: Compute time (vCPU-seconds or GB-seconds)
• Memory: Storage (GB-month) + queries
• Gateway: Tool registrations + invocations
• Browser/Code Interpreter: Execution time

Plus: Bedrock model calls, S3, Lambda, CloudWatch, networking, data transfer

Example (illustrative, verify current pricing):

• Harness: ~$0.05 per orchestration request
• Runtime: ~$0.0001 per vCPU-second
• Memory: ~$0.30 per GB-month + query costs
• Gateway: ~$0.01 per tool invocation
• Claude 5 Sonnet on Bedrock: ~$0.003/1K input tokens, ~$0.015/1K output

Cost control:

• Right-size Runtime compute
• Cache tool results to reduce Gateway invocations
• Use Memory selectively (not every interaction)
• Monitor token usage (largest cost driver)
• Batch requests when possible

When AgentCore costs fit:

• AWS is already your platform and service costs are acceptable
• Managed service convenience justifies metered pricing
• Tool invocations and memory queries are moderate
• Bedrock model pricing meets budget

When AgentCore costs don't fit:

• Self-hosted execution on reserved instances is cheaper at scale
• High tool invocation rate makes Gateway costs prohibitive
• Memory query volume exceeds budget for managed vector store
• Model costs require negotiated enterprise pricing unavailable on Bedrock

LangChain pricing

LangChain itself is open source (free). Costs are:

• Hosting: Your compute (EC2, ECS, Kubernetes, Lambda, GCP, Azure, Fly.io, etc.)
• Models: Direct API costs (OpenAI, Anthropic, Gemini, etc.) or self-hosted inference
• State storage: Postgres, Redis, vector DB (Pinecone, Weaviate, Qdrant, pgvector)
• Observability: LangSmith (optional, $99/month+) or your telemetry stack
• Operations: Engineering time for deployment, scaling, monitoring, incidents

Example (illustrative):

• EC2 m5.large (2 vCPU, 8 GB): ~$70/month reserved
• Anthropic Claude 5 Sonnet API: ~$0.003/1K input, ~$0.015/1K output
• Postgres RDS (db.t3.medium): ~$60/month
• Pinecone Starter: ~$70/month (1M vectors)
• LangSmith Team: ~$99/month

Cost control:

• Use reserved instances or spot for compute
• Cache LLM responses aggressively
• Choose cost-effective models (Claude Haiku, GPT-4o-mini for simpler tasks)
• Self-host vector DB (pgvector) instead of managed
• Minimize observability overhead (sample, not trace every call)

When LangChain costs fit:

• You have compute capacity or reserved instances
• Direct model API pricing beats managed service markup
• Self-hosted vector DB (pgvector) is acceptable
• Engineering team will handle operations
• LangSmith observability justifies its cost (or you skip it)

When LangChain costs don't fit:

• Operating hosting, databases, and observability exceeds managed service cost
• Team lacks capacity for infrastructure and incident response
• Managed services simplify budgeting (fixed meter rates vs. variable ops)

AgentLoop pricing

AgentLoop is a pattern (free). Costs depend entirely on your implementation:

• Infrastructure: Your compute (Alibaba Cloud, AWS, GCP, on-premise, etc.)
• Models: Direct API costs or self-hosted inference
• Storage: Your databases, vector stores, caches
• Observability: Your monitoring stack
• Operations: Engineering time to build and run the system

When AgentLoop costs fit:

• You're building from contracts and cost structure is flexible
• Infrastructure choice (cloud, on-premise, hybrid) is open
• Model access is negotiated enterprise pricing or self-hosted
• Team will implement and operate the full system

When AgentLoop costs don't fit:

• Implementation effort exceeds the benefit of control
• Managed services or frameworks provide sufficient value

Cost comparison summary

No universal cost winner exists. Model workload, tool invocation rate, hosting scale, and team capacity all determine actual cost.

How do you migrate between these frameworks?

Migration paths depend on what you own versus what's managed.

From AgentCore Harness to LangChain

What changes:

• Implement LangGraph state machine equivalent to Harness behavior
• Replace AgentCore Memory with LangChain memory store
• Replace Gateway tool catalog with MCP adapters or native tools
• Deploy hosting (Runtime, ECS, Kubernetes, etc.)
• Implement observability (LangSmith or custom)

What ports:

• Agent instructions (prompt engineering)
• Tool definitions (OpenAPI → LangChain tool schema)
• Memory namespace logic (if using Memory)
• Test cases and evaluation data

Effort: Medium to high (orchestration reimplementation)

From LangChain to AgentCore

What changes:

• Map LangGraph state machine to Harness configuration (or use Runtime)
• Migrate checkpointers and memory stores to AgentCore Memory (or keep custom)
• Migrate tools to Gateway registration (or keep MCP adapters via Runtime)
• Deploy on Runtime or use Harness
• Adopt CloudWatch observability (or keep LangSmith)

What ports:

• LangChain tool bindings
• Agent instructions
• Test cases

Effort: Medium (if Harness fits) to low (if using Runtime to host LangChain)

From either to AgentLoop

What changes:

• Implement AgentLoop contracts (Intent, Tool, Memory, Executor)
• Build orchestration per pattern (not porting Harness/LangGraph directly)
• Define workflow stages per handbook
• Implement monitoring per pattern

What ports:

• Agent intent and tool logic
• Test cases

Effort: High (building from pattern)

From AgentLoop to AgentCore or LangChain

What changes:

• Port Intent router to Harness config or LangGraph edges
• Port Tool implementations to Gateway or LangChain tools
• Port Memory to Memory service or LangChain store
• Adopt managed services (AgentCore) or framework (LangChain)

What ports:

• Agent logic, tools, memory

Effort: Medium (already have implementation)

Migration is not trivial in any direction, but hosting-level changes (Runtime vs. your infra) are easier than orchestration rewrites (Harness ↔ LangGraph).

How do you choose the right framework for your team?

Framework selection is not a single decision; it's a sequence of requirements and trade-offs.

Decision tree

Step 1: Do you want AWS to manage the orchestration loop?

• Yes, and Harness behavior fits → AgentCore Harness
• No, we need custom state machines → LangChain or AgentLoop
• Need to evaluate → Build the same workflow in Harness and LangGraph, compare

Step 2: Who operates the hosting?

• AWS (managed) → AgentCore Runtime
• Us (Kubernetes, EC2, etc.) → LangChain or AgentLoop on your infra
• Cloud-agnostic required → LangChain
• Alibaba Cloud preferred → AgentLoop + Alibaba services

Step 3: How much orchestration code will you own?

• Minimal (configuration preferred) → AgentCore Harness
• Moderate (framework integration) → LangChain
• Full control (architecture from contracts) → AgentLoop

Step 4: What are your memory and tool requirements?

• AWS-native, managed memory/tools → AgentCore Memory + Gateway
• Portable, framework-integrated → LangChain stores + MCP adapters
• Custom memory/tool layer → AgentLoop pattern or LangChain with custom stores

Step 5: What's your team's capacity?

• Manage config, not code → AgentCore Harness
• Manage framework code, not infrastructure → LangChain + managed hosting
• Manage full stack → LangChain or AgentLoop on your infra
• Build from contracts → AgentLoop

When to choose AgentCore

• AWS is your platform and service dependencies are acceptable
• Harness's orchestration behavior matches your workflow
• Managed memory and tool gateway reduce integration effort
• Team prefers configuration over orchestration code
• Budget accommodates metered managed services

When to choose LangChain

• Custom state machines, interrupts, or workflow logic are required
• Portable execution across clouds or on-premise is a priority
• Team has Python expertise and will own orchestration code
• Direct model API pricing or self-hosted inference is preferred
• Framework flexibility outweighs managed service convenience

When to choose AgentLoop

• You're designing agent architecture from requirements
• Alibaba's production pattern fits your workflow
• Implementation flexibility (framework, hosting, models) is a priority
• Team will build orchestration, memory, and tool layers
• No managed service or framework fully solves the problem

When to choose multiple (hybrid)

• Use LangChain on AgentCore Runtime when you need custom graphs but want AWS hosting
• Use AgentLoop contracts with LangChain implementation when the pattern fits but you want framework code
• Use AgentCore Gateway with LangChain agents when AWS tools are managed but orchestration is custom

What are the production readiness gaps?

All three approaches require additional work to reach production.

AgentCore production gaps

• Error handling: Harness retries are configurable; your code handles tool failures
• Evaluation: No built-in evals; bring your own test harness
• Deployment: Runtime deployment is managed; CI/CD to Runtime requires setup
• Cost monitoring: CloudWatch metrics exist; cost attribution per agent/user is custom
• Multi-tenancy: Namespace agents by user; Memory and Gateway namespaces are your logic
• Rate limiting: Gateway supports policies; application-level rate limits are custom
• Versioning: Harness config is versioned; Runtime containers are versioned; agent prompt versions are your schema

LangChain production gaps

• Hosting: Deployment, scaling, and observability are your responsibility
• State durability: Checkpointer backend (Postgres, Redis) must be operated
• Error handling: Implement retries, fallbacks, and circuit breakers in your graph
• Evaluation: LangSmith evals exist; custom test harness is common
• Multi-tenancy: Thread namespacing and user isolation are your logic
• Cost attribution: Trace costs per user/session via custom middleware
• Versioning: Agent graph versions and prompt versions are your schema

AgentLoop production gaps

• Everything: AgentLoop is contracts; you implement orchestration, hosting, memory, tools, monitoring, and operations

Shared gaps

• Prompt versioning and A/B testing: All three require custom systems
• Tool idempotency and transactionality: Your tool implementations must handle retries safely
• User feedback loops: Collect thumbs-up/down, corrections, and evaluation data
• Authorization: IAM, RBAC, or policy engines secure tool access and data
• Compliance: Data retention, deletion, audit logs, and PII handling are your responsibility

Production is more than framework choice. Build evaluation, monitoring, feedback, and authorization into your agent from the start.

What is the three-framework decision workflow?

Distilled into action:

1. Build a representative task in your top two choices. Config isn't enough; deploy a working agent.
2. Test interrupt-resume, tool errors, and state recovery. Most frameworks handle happy path; production is failure modes.
3. Measure actual costs. Run 1,000 interactions with realistic tool calls, memory queries, and model usage. Multiply.
4. Evaluate team ownership. Who maintains orchestration code? Who responds to incidents? Who operates hosting?
5. Accept the trade-off. Managed services cost more but reduce operational load. Code ownership gives control but requires maintenance. Patterns give flexibility but demand implementation.

There is no universally correct choice. The right framework is the one that matches your team's capacity, your workflow's requirements, and your cost constraints.

What did we just compare?

• AWS Bedrock AgentCore provides managed orchestration (Harness), custom framework hosting (Runtime), and integrated services (Memory, Gateway, Browser). Choose it for AWS-native managed loops.
• LangChain/LangGraph supplies an open-source framework for agent applications. You own orchestration, hosting, and state persistence. Choose it for custom graphs and portable execution.
• Alibaba AgentLoop documents a production agent pattern: intent routing, tool execution, memory, monitoring. You implement from contracts. Choose it when proven abstractions guide your architecture.

The decision is not "which is best" but "which ownership model fits your team, your workflow, and your platform constraints."

Evaluate with production scenarios: tool failures, state recovery, cost under load, and team capacity. Test, measure, then commit.
