Cloud Budgets: Your Guardrail Against Overspending
A cloud budget is a spending alarm for your cloud account. It warns you when costs approach a limit you've set, preventing surprise bills. Use it to track monthly spend or monitor usage. The main footgun: billing data lags, so you can overspend before an.
AWS Cost Explorer: Visualize and Forecast Your Cloud Spend
Cost Explorer is your cloud bill's interactive dashboard, turning raw data into trend graphs and forecasts. Use it to find which service is driving up costs or to predict next quarter's bill. The main footgun: once enabled, it cannot be disabled.
Consolidated Billing: Combine Cloud Bills for Bigger Discounts
Consolidated Billing is like a family phone plan for AWS accounts. It rolls multiple accounts into one bill, letting you share volume and savings plan discounts across the entire organization.
IaC State: The Map Between Your Code and the Cloud
IaC state is the source of truth mapping your code to real-world resources, acting as your tool's memory. Terraform uses a state file to plan updates, while other tools use a service backend. The footgun: never commit state files to Git; they lack locking and.
The Saga Pattern: Transactions Across Microservices
The Saga pattern manages transactions across services by chaining local operations. If a step fails, compensating actions undo previous work. It's common in booking systems.
Serverless State Machines: The Conductor for Your Functions
A serverless state machine is the conductor for your microservices, telling each function when to run and how to handle errors. It's built for multi-step processes like ETL pipelines or coordinating parallel tasks. The footgun is creating a visual monolith.
Idempotent Event Handlers: Don't Double-Count Events
An idempotent event handler ensures processing the same event multiple times has the same effect as processing it once. This is vital in event-driven systems to prevent data corruption from redelivered messages. The footgun is assuming exactly-once delivery.
AWS SAM: A Shorthand for Serverless on AWS
Think of AWS SAM as a developer-friendly shorthand for defining serverless applications. It simplifies creating Lambda functions and APIs by abstracting away verbose CloudFormation syntax, letting you build and test locally before deploying.
Cloud Native Buildpacks: No More Dockerfiles
Cloud Native Buildpacks turn source code into container images without a Dockerfile. This lets platform teams enforce security and best practices, while app developers just push code. The footgun is assuming they're simple; they're a full build system.
Promoting Code with Pipeline Stages
Think of pipeline stages as quality gates. Code must pass one gate, like 'build', before being promoted to the next, like 'deploy to staging'. This is core to CI/CD, moving code safely from dev to production. The footgun is making later stages less strict.
AWS CodeDeploy: Automated, Safe Application Updates
AWS CodeDeploy automates pushing your application to servers, Lambda, or ECS. It handles complex updates across many targets, letting you release new features rapidly while minimizing downtime.
AWS CodeBuild: Managed Builds Without the Servers
Think of AWS CodeBuild as an on-demand build server you don't manage. It's used in CI/CD to compile code, run tests, and create artifacts. The main footgun is thinking it's a full CI/CD platform; it's just the 'build' step, needing an orchestrator.
Procfile: Declare Your App's Startup Commands
A Procfile is the start script for your cloud app, telling the platform what commands to run. You use it to define processes like a `web` server for HTTP traffic or `worker`s for background jobs.
AWS DMS: Automating Database Migrations
AWS DMS automates moving data between databases, not just as a simple data pump. Use it for one-time migrations to the cloud or for continuous replication. The footgun is assuming DMS also converts your schema; for different engines, you must use the Schema…
Global Database: One Logical DB, Multiple Regions
A global database is a single logical database that spans multiple geographic regions, providing fast local reads and disaster recovery. It's used for apps with a worldwide user base that must survive regional outages.
Managed In-Memory Data Store: Speed Without the Sysadmin
A managed in-memory store is a high-speed valet for your data, sitting between your app and database to serve requests at microsecond latency. Use it for database acceleration or session stores. The footgun is treating it as a permanent database.
Managed Document Databases: Your Data, Their Ops
A managed document database is like a fully-staffed warehouse for your data. You store JSON-like objects, and the provider handles security, maintenance, and scaling. It's the default for cloud apps, but the convenience isn't free—watch for surprise bills.
Managed Key-Value Databases: Scaling Without Server Chores
A managed key-value database is like an outsourced dictionary. You give it a key, it returns a value, and the cloud provider handles all scaling and server management. It's used for session stores or user profiles where you need fast lookups by a known ID.
Database Multi-AZ: High Availability vs. Read Scaling
Multi-AZ deployment is like a hot spare database in another datacenter for automatic failover. It's for critical systems where downtime is costly. The footgun is assuming all standbys serve reads; only the 'cluster' type does, not the 'instance' type.
DDoS Mitigation: Surviving Traffic Floods
DDoS mitigation acts like a smart bouncer, learning your app's normal traffic to block malicious floods. It's used for any public internet endpoint, filtering attacks at the network and transport layers (L3/L4).
