Migration Considerations

Migration Step 1

E-Commerce Order Platform

Synchronous checkout with direct database payment insert and synchronous payment API call → Saga-orchestrated checkout with outbox-based fulfillment events

Streaming Media Platform

Synchronous transcoding in the upload request handler (blocking API response) → Async transcoding via Kafka topic with competing consumer workers

Both scenarios define a migration step at this stage. E-Commerce Order Platform: triggered by 'Payment provider timeout causing full checkout rollback and '. Streaming Media Platform: triggered by 'Upload API p99 exceeding 30 seconds due to in-process transc'.

Migration Step 2

E-Commerce Order Platform

PostgreSQL full-text search for product discovery → Elasticsearch for product search with CDC-based catalog indexing

Streaming Media Platform

Viewing history in PostgreSQL → Viewing history in Cassandra

Both scenarios define a migration step at this stage. E-Commerce Order Platform: triggered by 'Product search p99 > 1s; faceted navigation (category + pric'. Streaming Media Platform: triggered by 'PostgreSQL viewing history table exceeding 500M rows; write '.

Migration Step 3

E-Commerce Order Platform

Monolithic order processing with inline notification delivery → RabbitMQ-based notification fanout with dead-letter handling

Streaming Media Platform

Single CDN provider with no origin rate limiting → Multi-CDN with origin request coalescing and rate limiting

Both scenarios define a migration step at this stage. E-Commerce Order Platform: triggered by 'Email/push notification provider timeouts causing checkout l'. Streaming Media Platform: triggered by 'CDN provider incident causing total origin failover; CDN mis'.

Advisor Notes

E-Commerce Order Platform

Risk (high): Lock Contention

Concurrent writers to the same rows serialize behind each other's row locks, so latency is set not by the work a transaction does but by how long it waits for the writers ahead of it. On a hot row the queue depth, and therefore the tail latency, grows with concurrency while throughput flattens. Blocked writers hold connections open, so a single contended row can drain the connection pool as a secondary failure.

Streaming Media Platform

Risk (high): Queue Backlog Accumulation

Message queue or event stream consumer processing rate falls below producer write rate, causing consumer lag to grow unboundedly: eventually leading to increased end-to-end latency, producer backpressure, data expiry, or queue resource exhaustion.

Both

Shared Operational Requirements

Both scenarios require: Apache Kafka: scenario has team_maturity below senior, Apache Kafka: scenario uses Kafka for event streaming or CDC, Cache sizing and eviction policy configuration.

Where to Start

Start with E-Commerce Order Platform

Left

E-Commerce Order Platform has lower operational complexity. Starting here reduces risk and cognitive load. Migrate to the more capable architecture only when you hit concrete scaling or feature limits.

Complexity: high complexity, 21 nodes, 0 edges, 6 risks, 2 simulation seeds

Migrate when:

  • PostgreSQL pg_locks showing high RowExclusiveLock contention on inventory_items for specific sku_ids; checkout p99 > 2s for contended SKUs; deadlock errors appearing in application logs during sale events; effective checkout throughput for hot SKUs well below per-request checkout latency would predict → Introduce a per-SKU checkout serialization queue at the application layer : all concurrent checkout requests for the same SKU are queued and processed serially, converting lock contention into queue latency. Alternatively, use PostgreSQL advisory locks with non-blocking trylock: requests that cannot acquire the lock immediately return a "sold out" response rather than queuing. For very high flash sale volumes, pre-allocate inventory slots (reserve N slots per sale event, each slot is a row with one reservation) to spread lock contention across N rows instead of one.
  • Checkout p99 tracking payment provider p99 almost linearly; connection pool utilization on the payment service rising during payment provider slowdowns; circuit breaker trip events appearing in payment service metrics; saga timeout events correlated with payment provider latency spikes → Decouple the payment step from the synchronous checkout saga: reserve inventory and create the order record synchronously, then process payment asynchronously. The customer receives an "order confirmed, payment processing" state immediately; the payment step runs as a separate saga step triggered by an event. This reduces the synchronous checkout latency to the inventory reservation time, not the payment provider round-trip time.
  • CDC consumer lag on the Elasticsearch indexing consumer > 30s during catalog bulk updates; customer complaints about price changes not visible in search; search result prices diverging from checkout prices by more than the acceptable window; Kibana showing indexing throughput below the catalog update rate → Tune Elasticsearch bulk indexing batch size and flush interval to increase indexing throughput; add indexing consumer replicas with partition-based assignment to parallelize indexing across catalog segment partitions. Introduce a "price_as_of" timestamp in search results displayed to customers : this converts an invisible consistency gap into an explicit, auditable staleness signal that satisfies most checkout price dispute scenarios.

Decision Flow

1

Does your team have the operational maturity to run E-Commerce Order Platform (advanced rating)?

If Yes

Your team can operate E-Commerce Order Platform. Continue to Step 2 to refine based on risk tolerance and workload fit.

If No

Prefer the lower-maturity option: right scenario.

Right
2

Is operational stability and minimising production risk your primary concern over feature richness or scalability ceiling?

If Yes

Both scenarios carry similar risk weight. Continue to Step 3.

If No

Proceed to Step 3 to evaluate based on scaling requirements.

3

Do you expect your load to reach: PostgreSQL pg_locks showing high RowExclusiveLock contention on inventory_items for specific sku_ids; checkout p99 > 2s for contended SKUs; deadlock errors appearing in application logs during sale events; effective checkout throughput for hot SKUs well below per-request checkout latency would predict ?

If Yes

Left scenario has more defined scaling evolution paths for this growth pattern.

Left

If No

If you don't expect to hit these scaling signals soon, prefer the simpler architecture and re-evaluate when load patterns become clearer.

4

Is operational simplicity (fewer moving parts, easier debugging, lower ops burden) more important than maximum architectural capability?

If Yes

Both scenarios have equivalent complexity. Choose based on team preference.

If No

If capability and scalability ceiling matter more than simplicity, evaluate the higher-complexity scenario against your specific load model.

When to Choose Each Scenario

E-Commerce Order Platform

Left

When you need well-defined scaling thresholds and migration paths

High

E-Commerce Order Platform has more documented scaling evolution steps (4 thresholds, 3 migration paths).

When you want to minimise monitoring setup overhead

Moderate

E-Commerce Order Platform has a lower observability burden: fewer watched metrics and monitoring targets.

When your system requires decoupled async event processing

High

E-Commerce Order Platform includes event stream infrastructure (e.g., Kafka/Kinesis), enabling async decoupling between producers and consumers.

Streaming Media Platform

Right

When your system requires decoupled async event processing

High

Streaming Media Platform includes event stream infrastructure (e.g., Kafka/Kinesis), enabling async decoupling between producers and consumers.

When to Avoid Each Scenario

E-Commerce Order Platform

Left

When your team cannot mitigate: lock contention

High

This architecture is significantly exposed to Lock Contention. Concurrent writers to the same rows serialize behind each other's row locks, so latency is set not by the work a transaction does but by how long it waits for the writers ahead of it. On a hot row the queue depth, and therefore the tail latency, grows with concurrency while throughput flattens. Blocked writers hold connections open, so a single contended row can drain the connection pool as a secondary failure.

When your team cannot mitigate: cascading failure

High

This architecture is significantly exposed to Cascading Failure. A failure or degradation in one service causes increased load, held resources, or error propagation in its callers, which in turn degrade their callers, until the failure front propagates through the entire dependency graph and brings down services with no direct dependency on the original failure point.

When your team is early-stage or solo

High

E-Commerce Order Platform is rated 'advanced'. It requires experienced backend engineers or platform tooling to operate reliably at scale.

When you expect rapid growth within the next 12–18 months

Moderate

The advisor identifies 9 predicted bottlenecks for E-Commerce Order Platform. Rapid growth will surface these limitations quickly.

Streaming Media Platform

Right

When your team cannot mitigate: queue backlog accumulation

High

This architecture is significantly exposed to Queue Backlog Accumulation. Message queue or event stream consumer processing rate falls below producer write rate, causing consumer lag to grow unboundedly: eventually leading to increased end-to-end latency, producer backpressure, data expiry, or queue resource exhaustion.

When your team cannot mitigate: thundering herd (cache stampede)

High

This architecture is significantly exposed to Thundering Herd (Cache Stampede). When a popular cached key expires or a service recovers from downtime, all requests that were waiting or arrive simultaneously miss the cache and hit the origin database concurrently, producing a request spike that can overwhelm the database within seconds.

When your team is early-stage or solo

High

Streaming Media Platform is rated 'advanced'. It requires experienced backend engineers or platform tooling to operate reliably at scale.

When you expect rapid growth within the next 12–18 months

Moderate

The advisor identifies 9 predicted bottlenecks for Streaming Media Platform. Rapid growth will surface these limitations quickly.

Team Fit

Solo developer or small startup

Left

E-Commerce Order Platform is more accessible for small teams. Fewer operational moving parts reduces on-call burden.

  • Validate that the simpler architecture can handle your projected load before committing.

Small product team (2–6 engineers)

Left

E-Commerce Order Platform suits small teams that need to move fast without deep platform tooling investment.

  • Consider Streaming Media Platform only if your workload pattern specifically requires it.

Experienced backend team

Depends

An experienced team can operate either architecture. Choose based on workload fit, not team capability.

  • Prioritise alignment with existing infrastructure and tooling.
  • Streaming Media Platform may require additional runbook coverage and alerting investment.

Platform engineering team or SRE-equipped organisation

Right

A platform team can safely operate Streaming Media Platform and will benefit from its more advanced scaling characteristics.

  • Ensure observability and alerting are configured before launch.

Tier 1: Flash Sale Inventory Contention: Concurrent saga checkout attempts competing for the same inventory row via row-level locking. Recommended evolution: Introduce a per-SKU checkout serialization queue at the application layer : all concurrent checkout requests for the same SKU are queued and processed serially, converting lock contention into queue latency. Alternatively, use PostgreSQL advisory locks with non-blocking trylock: requests that cannot acquire the lock immediately return a "sold out" response rather than queuing.

Tier 2: Payment Provider Latency Amplifying Checkout Latency: Checkout saga holding a database connection and an inventory reservation open for the duration of the payment provider call: payment latency directly amplifies connection pool pressure. Recommended evolution: Decouple the payment step from the synchronous checkout saga: reserve inventory and create the order record synchronously, then process payment asynchronously. The customer receives an "order confirmed, payment processing" state immediately; the payment step runs as a separate saga step triggered by an event. This reduces the synchronous checkout latency to the inventory reservation time, not the payment provider round-trip time. .

Tier 1: Transcoding Worker Throughput: Transcoding consumer group undersized relative to peak upload volume. Recommended evolution: Increase transcoding consumer instances up to the transcoding topic partition count; tune partition count to match the maximum desired worker parallelism (set this at topic creation, not after lag appears); implement per-uploader upload rate limits to smooth burst input; consider priority queuing so premium-tier content does not wait behind bulk ingest jobs .

Recommended evolution: Implement origin request coalescing (single origin fetch per CDN node per object, queue subsequent requestors for the in-flight response); pre-warm CDN edges for anticipated high-traffic content before publish; add rate limiting at the origin gateway to cap per-second origin requests per content_id .

Elasticsearch: scenario has full_text_search or log_analytics workload

Left

Configure ILM policies from day one to prevent shard explosion as data grows

Elasticsearch: scenario uses Elasticsearch as a primary datastore

Left

Elasticsearch is a search index, not a source of truth: add a durable primary store and sync to ES

Apache Cassandra: scenario has team_maturity below staff_plus

Right

Cassandra has the highest operational complexity of common datastores: consider managed options (Astra DB, Keyspaces) or simpler alternatives

Right

MinIO's per-request overhead reduces effective throughput for small objects; evaluate aggregating small objects into larger archives or using a key-value store for small object access patterns

Required maturity: mid_level

Generator Constraints

E-Commerce Order Platform

Left

Generator relevance documented but not yet production-ready.

For e-commerce product briefs, the generator must output the full saga orchestration template: forward path (reserve_inventory → charge_payment → confirm_order → notify_fulfillment) and compensation path (release_inventory, refund_payment, cancel_order) as first-class generated artifacts. Inventory reservation schema (with SELECT FOR UPDATE NOWAIT), outbox table schema, and idempotency key persistence pattern must be generated as required components. RabbitMQ dead-letter exchange configuration must be generated alongside the primary queue configuration.

Streaming Media Platform

Right

Generator relevance documented but not yet production-ready.

For content platform briefs with video or audio delivery requirements, the generator should output the Kafka async transcoding pipeline, MinIO object storage, and CDN-first delivery as the canonical composition. Redis playback session with TTL enforcement and Cassandra for time-ordered viewing history should be generated as separate store responsibilities. The generator must flag the partition key design decision for the Cassandra history table as a mandatory architecture decision requiring explicit access pattern enumeration before schema creation.
