cost optimization
798 articles on cost optimization — what drives the cost, how it is priced, and where the savings actually are.
AWS GuardDuty cost explained: per GB and per event analyzed
GuardDuty bills by the volume of logs and events it analyzes, CloudTrail events, VPC flow logs, DNS logs, and per feature (S3, EKS, malware, RDS protection). High-traffic accounts and enabled features drive the bill. Here is the model.
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.
Cloud security tooling cost: budgeting for the security stack
Security tools, threat detection, posture management, WAF, secrets, DDoS, add up across a cloud estate. Most are usage- or resource-based, so the stack cost scales with your footprint. Here is how to budget for it sensibly.
Data egress cost optimization: the tax on moving data out
Egress, data leaving a cloud to the internet or across regions, is billed per GB and is one of the most underestimated cloud costs. Architecture, caching, and keeping traffic in-region cut it. Here is how.
Multi-region cost tradeoff: what high availability really costs
Running across regions buys resilience and lower latency for distributed users, but roughly multiplies infrastructure cost and adds cross-region data transfer. The tradeoff is availability and latency versus cost. Here is how to weigh it.
AWS Fault Injection Service cost: per action-minute of experiments
FIS bills per action-minute of chaos experiments (about $0.10), so cost scales with how long and how many fault-injection actions run. It is cheap relative to the resilience it validates. Here is the model and how it fits.
AWS CloudTrail Lake cost: per GB ingested and scanned
CloudTrail Lake bills per GB of events ingested into an event data store (by pricing tier and retention) plus per GB scanned by queries. High-volume event ingestion and broad queries drive the bill. Here is the model.
AWS Location Service cost: per request, by capability
Amazon Location Service bills per request across maps (tiles), places (geocoding, search), routes, and trackers/geofences, each priced separately with a free tier. High-volume mapping and per-position tracking drive the bill. Here is the model.
Azure Data Explorer cost: cluster compute plus storage
Azure Data Explorer (Kusto) bills the compute of its cluster VMs (with a markup) plus storage, running continuously unless stopped, or serverless-style with autoscale. Idle clusters and over-provisioning drive the bill. Here is the model.
Azure Web PubSub cost: per unit per day, like SignalR
Azure Web PubSub bills per provisioned unit per day (each supporting concurrent connections and messages), with a Free tier and autoscaling Premium. Over-provisioning units for rare peaks drives the bill. Here is the model.
GCP Datastream cost: per GB of change data processed
Datastream bills per GB of change-data-capture (CDC) data processed from source databases, plus backfill of existing data. High-change-rate sources and large backfills drive the bill. Here is the CDC replication model.
GCP Workflows cost: a few cents per thousand steps
Google Cloud Workflows bills per step executed, with internal steps very cheap (and a free tier) and external HTTP calls slightly more, so orchestration itself is nearly free. The real cost is what the steps call. Here is the model.
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.
WebSockets vs polling: the cost of real-time updates
Polling for updates repeatedly hits your backend whether or not anything changed; WebSockets push updates over a persistent connection only when they occur. For frequent updates to many clients, the cost tradeoff is nuanced. Here it is.
Async processing: how queues and workers cut cost under load
Processing work synchronously means provisioning compute for peak request rate; processing it asynchronously via a queue lets workers drain at their own pace, so you provision for average, not peak. This decouples cost from spikes. Here is the tradeoff.
Cloud cost governance: policies that prevent waste before it happens
Cost governance encodes rules, required tags, banned expensive SKUs, budget limits, allowed regions, that are enforced automatically rather than left to discipline. Enforced in CI and at provisioning, they prevent waste at the source. Here is how.
AWS Network Firewall cost: endpoint hours plus data processed
Network Firewall bills a per-endpoint hourly fee (per Availability Zone) plus per GB of traffic inspected. The always-on per-AZ endpoint fee is the surprise. Centralizing inspection is the lever. Here is the model.
AWS Outposts cost: paying for AWS hardware in your data center
Outposts brings AWS infrastructure on-premises, priced as a capacity commitment (upfront and/or monthly over a 3-year term) for the rack or servers. It suits low-latency or data-residency needs, at a substantial fixed cost. Here is the model.
AWS Lake Formation cost: free governance, you pay for the storage-optimizer
Lake Formation's governance and permissions add no direct charge; you pay for the underlying S3, Glue, and Athena, plus a storage-optimization (compaction) charge for governed tables. The underlying services are the real cost. Here is the model.
AWS CloudHSM cost: dedicated hardware security modules by the hour
CloudHSM bills per HSM instance-hour (around $1.45, so about $1,000+/month each), and you need at least two for high availability. It is expensive dedicated hardware for strict compliance needs. For most, KMS is far cheaper. Here is when CloudHSM is required.
Azure App Configuration cost: free tier or a small daily fee
App Configuration has a free tier for basic use and a Standard tier billed a small daily fee plus per-10,000-request overage beyond a generous included allowance. It is inexpensive; the main lever is caching config to reduce requests. Here is the model.
Azure SignalR Service cost: per unit per day, by tier
SignalR Service bills per provisioned unit per day (Standard) or by usage (Serverless-friendly), with each unit supporting a number of concurrent connections and messages. Over-provisioning units for peak that rarely comes drives the bill. Here is the model.
GCP Certificate Manager cost: public certs free, private CA priced
Google-managed public TLS certificates are free; the cost is Certificate Authority Service for private CAs, billed per CA per month plus per certificate issued. For public TLS, there is nothing to pay. Here is the model.
