Context Engineering for AI Agents: What to Feed an Agent and What to Leave Out

Picture a Monday at 03:10 UTC. An agent investigating an out-of-memory alert on payment-service works out the pattern: it runs out of memory every Monday between 03:00 and 04:00, and the spike lines up with the batch reconciliation job. The next Monday the alert fires again. A different agent picks it up and starts from zero, because nothing it can see holds what the first one learned.

Shipped: Views now work for every access level

Most people who open CloudZero care about one slice of the spend, like their team, their product, or their region. A View gives them that slice in one click, with the grouping and filters already set, so nobody has to rebuild the same Explorer query every week. Views now work for everyone in your organization, including people with scoped access.

Certificate monitoring with TLS, chain, and post-quantum readiness

Most customers start CertKit with SSL host monitoring. On day one, you point CertKit at the systems you already run and get every certificate and when it expires. You start with confidence that you have everything under control. Then, you automate, letting CertKit take over the certificates as they need to be renewed. Each renewal is the last time you ever have to worry about that certificate.

pgvector for RAG: When you don't need a dedicated vector database

Dedicated vector databases have become such a standard part of the RAG conversation that teams often add one before they have proved they need it. According to studies, over 70% of companies using LLMs are using vector databases and RAG to customize their models. That shows how quickly the pattern has become normal. However, it does not mean every RAG application needs a separate retrieval system. If your application already runs on PostgreSQL, pgvector may be enough.

How to Guarantee a Website or Service Never Goes Down (And What You Can Actually Promise)

No one can guarantee that a website or service never goes down. What you can promise is a measured availability target, and with a multi-location, active-active design you can reach 99.999% (five nines), about 5 minutes 15 seconds of downtime a year. That takes redundancy at every layer, automatic health-based failover across regions and ideally providers, safe deployments, failure testing, and outside-in monitoring. Control Plane is built for that tier.
