The 90s called—they want their PDF files back!

It’s amazing how prescient the creators of the PDF were. In 1993, they designed a file format that captured physical output in extremely high fidelity. Twenty-five years later, PDF is the gold-standard for content distribution.

And ESG has always delivered technical validations—and much of the rest of our content—as PDF files.

Motive, Means, and Opportunity for Evaluating HCI Performance

With all the hype surrounding hyperconverged infrastructure (HCI), ESG’s technical validation practice has been busy evaluating various HCI solutions.

Thus, buying criteria has evolved from answering “Can this offering support my applications?” to “How well can it support my application?”

IBM's cloudy future

Last week, I attended IBM’s Cloud Summit in New York. This was IBM’s opportunity to re-affirm its commitment to the cloud, and to enlighten us about IBM’s future. Over the course of the day, IBM Cloud’s senior management team detailed their cloud strategy, execution, and future plans.
