Dell said that it planned to launch an online analytics service in the first half of this year for small and midsized businesses, but that service isn't due now until early next year, a Dell executive said.

"Like a lot of development projects, it can take a bit longer than you think," Paulette Altmaier, general manager of Dell's Cloud Business Applications group, said in an interview Thursday.

Dell also said it would launch a platform-as-a-service offering this year based on Microsoft's Azure platform. On Friday, a Dell spokeswoman said the company no longer has a delivery date for that service.

The delays are a setback for Dell, which is trying to reduce its dependence on PCs and build more profitable businesses in services and software. But a lot of companies are moving slowly to the cloud, so the hold-up isn't a disaster, said Peter ffoulkes, an industry analyst with 451 Research Group.

"The move to the cloud is not a fast journey and for most people it is still largely a future. I would not expect a quarter or two to make a big difference in practical terms," he said.
