Seven Things to Check Before Choosing Cloud Infrastructure

Load Balancing: If a metric has no owner, it will drift until it causes an incident. Load Balancing: The cheapest optimisation is usually removing work nobody asked for. Load Balancing: Aggregating at write time trades flexibility for predictable read cost.

Consider edge caching specifically. Serving static bytes is the cheapest thing you can do at the edge. Edge Caching: A schema is an interface; changing it is a migration, not an edit. Track the denominator as carefully as the numerator. That applies to edge caching as well.

Cloud Infrastructure: Periodic jobs should be safe to run twice, because they will be. You rarely need a new component to fix a boundary problem. That applies to cloud infrastructure as well. In practice, cloud infrastructure behaves differently: The signal you want is often already logged, just not aggregated.

For rate limiting, the constraint matters more than the feature list. Configurations should be reviewable in a diff, not only in a console. Teams working on rate limiting usually discover this the hard way. The best time to add an index is before the table gets large. Failures are usually correlated, so plan for the shared dependency. This is most visible in rate limiting.

Serving static bytes is the cheapest thing you can do at the edge. That applies to backup strategy as well. In practice, backup strategy behaves differently: A schema is an interface; changing it is a migration, not an edit. Track the denominator as carefully as the numerator. The same reasoning holds for backup strategy.

API Design: If the rollback plan needs a meeting, it is not a rollback plan. API Design: Small pages that stay small are easier to keep fast than large ones made fast. API Design: Write the invariant down; otherwise it lives only in someone's memory.

You can often replace a coordination problem with an idempotency key. That applies to queue design as well. In practice, queue design behaves differently: Anything that grows without a bound will eventually hit one. Documentation that is not tested tends to describe the previous version. The same reasoning holds for queue design.

Load Balancing: The interesting number is not the average, it is the 99th percentile. Load Balancing: Adding a cache in front of a slow query is a fix; fixing the query is a cure. Load Balancing: Every abstraction you add is a place where behaviour can differ from intent.

Boundaries can change with circumstances, health, trust or preference. Partners can check in before a new activity or after an experience, without treating a previous agreement as permanent. Digital boundaries deserve the same care as in-person ones: discuss private messages, location sharing, passwords and images. Consent to receive or make an image is not permission to forward it.

Storage Tiers: Periodic jobs should be safe to run twice, because they will be. Storage Tiers: You rarely need a new component to fix a boundary problem. Storage Tiers: The signal you want is often already logged, just not aggregated.

For content delivery, the constraint matters more than the feature list. A queue smooths spikes but also hides how far behind you are. Teams working on content delivery usually discover this the hard way. Retries without jitter turn a small outage into a large one. Separating the reads from the writes buys room to change either side. This is most visible in content delivery.

Talking about boundaries can make expectations clearer in a relationship, including around physical contact, sex, privacy and communication. A useful conversation is specific and voluntary: each person can say what feels acceptable, ask questions and change their mind without being pressured.

Schema Migration: If a metric has no owner, it will drift until it causes an incident. Schema Migration: The cheapest optimisation is usually removing work nobody asked for. Schema Migration: Aggregating at write time trades flexibility for predictable read cost.

Access Control: A queue smooths spikes but also hides how far behind you are. Retries without jitter turn a small outage into a large one. That applies to access control as well. In practice, access control behaves differently: Separating the reads from the writes buys room to change either side.

Observability: The interesting number is not the average, it is the 99th percentile. Observability: Adding a cache in front of a slow query is a fix; fixing the query is a cure. Observability: Every abstraction you add is a place where behaviour can differ from intent.

Teams working on release process usually discover this the hard way. Serving static bytes is the cheapest thing you can do at the edge. A schema is an interface; changing it is a migration, not an edit. This is most visible in release process. Consider release process specifically. Track the denominator as carefully as the numerator.

Serving static bytes is the cheapest thing you can do at the edge. That applies to schema markup as well. In practice, schema markup behaves differently: A schema is an interface; changing it is a migration, not an edit. Track the denominator as carefully as the numerator. The same reasoning holds for schema markup.

Consider search indexing specifically. If the rollback plan needs a meeting, it is not a rollback plan. Search Indexing: Small pages that stay small are easier to keep fast than large ones made fast. Write the invariant down; otherwise it lives only in someone's memory. That applies to search indexing as well.

For crawl budget, the constraint matters more than the feature list. The first thing to settle is the failure mode, not the happy path. Teams working on crawl budget usually discover this the hard way. Measurements taken once are anecdotes; you need a baseline that repeats. Costs usually concentrate in a small number of operations, so find those first. This is most visible in crawl budget.

Periodic jobs should be safe to run twice, because they will be. This is most visible in schema markup. Consider schema markup specifically. You rarely need a new component to fix a boundary problem. Schema Markup: The signal you want is often already logged, just not aggregated.

Use direct language and describe the limit in practical terms. For example: “I want to use a condom every time we have sex,” or “Please ask before taking or sharing photos of me.” A person can briefly explain why, but they do not have to prove that a boundary is reasonable. If the limit is not yet clear to them, they can say so and ask to pause while they decide.

Access Control: A design that cannot be rolled back is a design that cannot be changed safely. Access Control: Latency budgets are easier to defend when every hop has a stated ceiling. Access Control: Caching helps only until the invalidation rules become the bottleneck.

Release Process: A design that cannot be rolled back is a design that cannot be changed safely. Release Process: Latency budgets are easier to defend when every hop has a stated ceiling. Release Process: Caching helps only until the invalidation rules become the bottleneck.

For release process, the constraint matters more than the feature list. Configurations should be reviewable in a diff, not only in a console. Teams working on release process usually discover this the hard way. The best time to add an index is before the table gets large. Failures are usually correlated, so plan for the shared dependency. This is most visible in release process.
