Every number in CloudZero comes from a billing connection. When a credential expires or a permission changes, that connection stops sending data, and your reports show less spend than you actually have. If you catch it early, you can fix the connection before month-end close. You also need to know what broke. For Azure and Snowflake connections, CloudZero now tells you which check failed, so you can send the fix to the right person without opening a support ticket.

Training an AI model costs anywhere from a few hundred dollars to several hundred million, depending entirely on what “train” means. Fine-tuning an existing model: tens to thousands of dollars. Pretraining a small model from scratch: tens of thousands to millions. A frontier run in 2026: hundreds of millions, with Epoch AI projecting the largest runs will pass $1 billion by 2027.

If you’re researching AWS desktop virtualization and application delivery services, it is likely that you have come across Amazon WorkSpaces and Amazon WorkSpaces Applications. While the names sound similar, these two AWS services address different requirements. Amazon WorkSpaces provides a complete cloud desktop, while Amazon WorkSpaces Applications focuses on securely delivering individual applications through AWS-managed application streaming.

How a SharePoint Administrator locks a site with Set-SPOSite: ReadOnly, NoAccess and Unlock, how to check the state, and why an unlock command sometimes fails.

On October 20, a power failure in one of Google Cloud’s three London zones disrupted Revolut, Lloyds, HSBC and others for hours. One zone failed, errors spread region-wide, and Google warned customers they might not be able to create new workloads to fail over to. Most teams find out how resilient they are during an outage, not before one. These five questions let you find out first.

Qovery now sends your organization ID as the sts:ExternalId when it assumes the IAM role in your AWS account, and the role's trust policy only accepts it on behalf of your organization. Your role is already updated. If you manage it with the qovery-role-creation CloudFormation stack, update the stack to the latest template. Romain is a staff engineer at Qovery working on the control plane and AI integrations. He writes about distributed systems, incident response, and MCP-based tooling.

What a SharePoint hub site is, the 2,000 hub limit, how to register one in the admin center, who can associate sites, and how to delete or archive a hub.

Why OneDrive stops syncing a SharePoint library: the 300,000-item limit, invalid names, 400-character paths, 250 GB files, read-only libraries and full storage.

Enterprises are putting hard ceilings on AI spend. Accenture now centrally funds $29 a month per person for Claude and charges anything above that to a project budget code. Uber used up its 2026 AI budget in four months and restricted access. A cap stops waste and useful work at the same rate. The alternative is seeing AI cost by team, by project and by outcome, then funding what returns. Companies spent the past year telling employees to use more AI. Now a lot of them are putting a lid on it.

You can already break down cloud spend by team, product, or customer in Explorer. But AI spend has been harder to decompose. Which models is each team running? What activity is driving the cost growth you saw this month? Before AI Explorer, answering those questions meant exporting raw event data and building your own breakdowns, or waiting days for reconciled billing to land in Explorer.
