Practical guides on cloud costs, hosting decisions, and strategies to get the most out of your infrastructure.
Cloud server pricing starts at $4.99/mo on Raff. Compare compute, storage, backups, bandwidth, Windows licensing, billing terms, and real monthly cost.
Compare database migration services by scope, cost drivers, downtime, validation, rollback, and provider responsibilities before moving PostgreSQL or MySQL.
Compare database hosting services for production apps by engine support, backups, PITR, HA, private networking, scaling, pricing, migration, and support.
Optimize ClickHouse queries by designing ORDER BY and sparse primary keys for pruning, measuring rows/bytes read, and controlling aggregation, memory, joins, and concurrency.
Monitor ClickHouse query latency, rows read, memory, parts, merges, mutations, replication, Keeper, disk growth, and ingestion freshness with actionable alerts.
Design ClickHouse backups and replication for availability and recovery: separate replicas from historical backups, define RPO/RTO, monitor Keeper, and test restores.
Design ClickHouse partitioning and TTL for MergeTree tables: keep partitions coarse, use ORDER BY for queries, and automate safe retention without part explosion.
Use ClickHouse materialized views for pre-aggregation without losing correctness: compare incremental vs refreshable views, backfills, target tables, and write trade-offs.
Design Kafka retention across time and size limits, delete vs compact cleanup, replication, ISR durability, consumer replay windows, and storage capacity.
Compare Redis vs Valkey across protocol compatibility, clients, persistence, modules, operations, and safe migration for cache, sessions, and queues.
Choose a Redis eviction policy across LRU, LFU, volatile policies, noeviction, maxmemory, TTLs, and mixed cache/session/queue workloads.
Compare Redis RDB snapshots and AOF persistence across durability, data-loss windows, restart behavior, disk overhead, and recovery requirements.
