Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.

Nemertes Research polled dozens of IT executives earlier this year to find out what is top of mind for today’s data center customers. Here are the four big trends the survey uncovered: consolidation, growth, availability and operational efficiency.

Andreas Antonopoulos, principal research analyst at Nemertes, says there is a big transformation underway in today’s data centers and CIOs, IT directors, data center managers and other IT professionals are focusing on the four areas mentioned above as their biggest challenges.

Companies are centralizing IT resources in an effort to streamline management. At the same time, they’re finding they need to bring in more servers to support a growing demand – that feeds in to the heat/power/cooling issue that is becoming increasingly important in designing today’s data centers.

Antonopoulos says half of the survey respondents list availability as one of their top challenges as businesses demand more highly reliable applications. As a result, more than half of the respondents are setting up secondary data centers for disaster recovery and business continuity, he says.

Finally, companies are taking a closer look at data center management and operations in an effort to cuts costs and improve efficiency. This, a significant majority of the survey respondents say, is part of the whole move toward delivering IT as an on-demand service.

Antonopoulos will explore these four trends in more detail in his newsletter in the coming weeks. Sign up for the New Data Center Strategies newsletter here.
