26 articles on comparison — what drives the cost, how it is priced, and where the savings actually are.
DNS cost compared: Route 53 vs Azure DNS vs Cloud DNS
Managed DNS (Route 53, Azure DNS, Cloud DNS) prices by hosted zones plus queries, all inexpensive, with health checks and traffic policies adding cost. The cheapest is usually the one native to your cloud. This compares them.
Self-hosted CI runners: when they cost less than hosted
Self-hosted CI runners run on your own infrastructure, trading per-minute hosted pricing for instance cost plus operational effort. At high build volume, or with Spot and autoscaling, they cost less. Here is the tradeoff.
Feature flags cost: managed platforms vs self-hosted
Feature flag platforms (LaunchDarkly, Split, and others) price by seats, monthly active users, or flag evaluations; self-hosted or open-source options trade that for infrastructure. Evaluation volume and MAU drive managed cost. Here is the model.
Log management cost compared: ingest, index, and retain
Log platforms (Datadog Logs, Splunk, Elastic, Loki, cloud-native) price by ingestion, indexing, and retention, with very different models. Ingest less, index selectively, and tier retention to cut the bill. This compares the approaches.
Status page cost: hosted services vs self-hosted
Status pages communicate incidents and uptime to users, via hosted SaaS (per-subscriber or feature tiers) or self-hosted (open-source plus hosting). For most, hosted is cheap; self-hosted suits scale or customization. Here is the model.
GPU instance cost compared: choosing the right accelerator
GPU instances vary enormously in cost, from older inference GPUs to top training accelerators costing many dollars per hour. Matching GPU class to the workload, and using Spot, drives the bill. This compares the tradeoffs.
Model serving cost: managed endpoints vs self-hosted
Serving a model can use a managed endpoint (SageMaker, Vertex, Azure ML) that bundles ops at a premium, or self-hosted serving on your own compute that is cheaper per hour but adds operational burden. Here is the tradeoff.
Secrets management cost compared: AWS vs Azure vs GCP vs Vault
AWS Secrets Manager charges per secret per month plus API calls; Azure Key Vault and GCP Secret Manager charge mostly per operation with cheap or free storage; self-hosted Vault trades license or ops cost. This compares the models.
WAF cost compared: AWS WAF vs Azure vs Cloud Armor
AWS WAF charges per web ACL, per rule, and per million requests; Azure WAF and GCP Cloud Armor bundle differently (policy plus per-rule plus requests). The cheapest depends on rule count and traffic. This compares the models.
DDoS protection cost compared: AWS Shield vs Azure vs Cloud Armor
AWS Shield Standard is free with Advanced a flat monthly commitment; Azure DDoS Protection is a flat plan or per-IP; GCP relies on always-on network protection plus Cloud Armor. The models differ sharply. This compares them.
SIEM cost compared: Sentinel vs Security Lake vs Chronicle
SIEM cost is dominated by data ingestion: Microsoft Sentinel bills per GB ingested (with commitment tiers), AWS Security Lake centralizes data in S3 with usage-based analytics, and Google Chronicle prices differently. Ingestion volume drives all. This compares them.
Container registry cost compared: ECR vs ACR vs Artifact Registry
AWS ECR and GCP Artifact Registry price per GB stored plus egress; Azure ACR uses a flat daily tier fee bundling storage. The cheapest depends on registry size and pull topology. This compares the models and the shared levers.
Monitoring cost compared: CloudWatch vs Azure Monitor vs Cloud Monitoring
CloudWatch, Azure Monitor, and Google Cloud Monitoring all bill on metrics, logs ingested, and API calls, with generous free tiers for platform metrics. Logs and custom metrics drive the bill. This compares them and the shared levers.
Secrets management cost compared: Secrets Manager vs Key Vault vs Secret Manager
AWS Secrets Manager charges per secret per month plus API calls; Azure Key Vault and GCP Secret Manager charge mostly per operation with tiny per-secret fees. The cheapest depends on secret count vs access frequency. This compares them.
API gateway cost compared: API Gateway vs API Management vs Cloud endpoints
AWS API Gateway, Azure API Management, and GCP's API Gateway/Cloud Endpoints price API management differently, per-request vs tiered subscription vs per-call. The cheapest depends on volume and feature needs. This compares them.
Load balancer cost compared: AWS vs Azure vs GCP
AWS (ALB/NLB), Azure (Load Balancer, Application Gateway), and GCP (Cloud Load Balancing) price load balancing on hourly plus capacity/data axes. Layer-4 is cheaper than layer-7. This compares them and the shared choice of layer to your needs.
CDN cost compared: CloudFront vs Front Door vs Cloud CDN
CloudFront, Azure Front Door, and Google Cloud CDN price content delivery similarly, egress to users (tiered by region) plus requests, with free origin-to-CDN transfer. The cheapest depends on traffic geography and volume, and a CDN usually lowers total cost.
Data warehouse cost compared: Redshift vs BigQuery vs Synapse
Redshift, BigQuery, and Synapse price data warehousing on different axes, provisioned nodes or serverless, per-TB-scanned or per-slot, per-DWU. The cheapest depends on query pattern and volume, not the platform. This compares the models.
NoSQL database cost compared: DynamoDB vs Firestore vs Cosmos DB
DynamoDB, Firestore, and Cosmos DB price NoSQL differently, DynamoDB per capacity or request, Firestore per operation, Cosmos per request unit or serverless. The cheapest depends on read/write mix and traffic shape. This compares the models.
Managed PostgreSQL cost compared: RDS vs Cloud SQL vs Azure Flexible Server
AWS RDS, GCP Cloud SQL, and Azure Database for PostgreSQL Flexible Server price managed Postgres similarly, compute per vCPU and memory, storage, and high-availability options. The cost drivers and levers are shared. This compares them.
Block storage cost compared: EBS vs Managed Disks vs Persistent Disk
AWS EBS, Azure Managed Disks, and GCP Persistent Disk price block storage similarly, by provisioned capacity and performance tier, with the fastest tiers charging for provisioned IOPS. This compares them and shows the shared optimization levers.
Managed Kubernetes cost compared: EKS vs AKS vs GKE
EKS, AKS, and GKE all charge for the worker nodes; the difference is the control-plane fee (EKS and GKE charge per cluster-hour, AKS's standard tier is free) and autopilot-style options. This compares them and where the real cost lives.
Message queue cost compared: SQS vs Pub/Sub vs Service Bus
SQS, Google Pub/Sub, and Azure Service Bus price messaging differently, SQS per request, Pub/Sub per TiB of throughput, Service Bus per operation or messaging unit. This compares the models and the surprises in each.
Object storage cost compared: S3 vs Cloud Storage vs Blob
S3, Google Cloud Storage, and Azure Blob price object storage similarly, tiered storage, request charges, and egress, but the details and egress rates differ. This compares the three and shows why egress, not storage, usually decides the bill.
