Clear, opinionated, side-by-side breakdowns of the choices that come up in every cloud interview and production systems design. When to use what, and why.
Kubernetes is the industry standard for multi-cloud, open-source container orchestration. AWS ECS is AWS's simpler, opinionated, native alternative. The choice is between power/portability and simplicity/native integration.
Terraform provisions infrastructure (VPCs, databases, VM instances) declaratively. Ansible configures software on running machines (installs packages, configures files) imperatively. They are highly complementary and commonly paired.
ArgoCD is a GitOps continuous delivery tool featuring a comprehensive graphical UI dashboard. FluxCD is a modular, lightweight set of Kubernetes controllers that runs invisibly. The choice is visual dashboard comfort vs raw Kubernetes-native automation.
HashiCorp Vault is a multi-cloud secret manager that stores values and generates dynamic credentials. AWS KMS is an HSM-backed cryptographic service that generates and manages keys to encrypt/decrypt data. Most organizations use both.
Elasticsearch indexes the full text of all log lines for fast, complex queries at a high storage cost. Grafana Loki only indexes log metadata labels, storing raw logs in object storage (S3) for low-cost aggregation.
Prometheus is an open-source, pull-based metrics monitoring database hosted inside your own clusters. Datadog is a fully managed, agent-based commercial SaaS observability platform. The choice is open-source hosting control vs vendor management convenience.
Helm packages Kubernetes configurations into versioned charts using a Go templating engine. Kustomize uses a template-free overlay mechanism to patch base configurations for different environments (dev, prod).
SQS is a queue service (point-to-point) where each message is processed by exactly one worker. SNS is a pub/sub service (broadcast) where a single message is pushed to multiple subscribers simultaneously.
