  • What's to gain by adopting all-flash arrays?

    All-flash arrays increase the number of VMs allowed per physical host. This affects the configuration, performance and even spending decisions in a virtualized data center. Powerful all-flash arrays compress data at impressive levels. As a result, admins who put flash into action in a data center can improve storage performance and at the same time increase the number of VMs per physical host.

    This has effects on server selection, VM configuration and overall performance of an IT infrastructure. While there'll be reasonable concerns about the purchase costs, there are factors that can make calculating the ROI for an all-flash array less daunting. This three-part guide explores these issues and considers why an organization might consider adopting all-flash arrays.

  • A glimpse into the future reveals business apps in the cloud

    Not too long ago, few organizations considered putting all their business apps in the cloud. Moving applications off-premises was an innovative tech experiment only the most adventurous undertook. Today it's a different story. Cloud computing is practically a mainstream option, with more and more organizations placing more and more of their business apps in the cloud.

    What they're not doing is doing it wholesale. They're moving applications bit by bit, and these gradual rollouts often turn into enterprisewide cloud deployments. "They are picking where they start, and they're figuring out what's an area of low risk or saying, 'I've got to automate this process that we've done on spreadsheets, ' " said Christine Dover, an IDC analyst, in the cover story of this issue of Business Information.

    Tony Kontzer's story explores cloud projects at chain restaurant operator Ovation Brand and One Call Now, a provider of mass-messaging services. Ovation turned to software-as-a-service (SaaS) apps to replace its aging Oracle system, putting business apps in the cloud one by one. One Call Now started using SaaS applications after outgrowing on-premises software.

    Such is the state of business applications today -- and tomorrow. Another story looks at another side of that future: organizations juggling lots and lots of apps. James Denman talks to folks at Arizona State University and Canadian phone directory publisher Yellow Pages about their project portfolio management (PPM) initiatives. One is far ahead in the practice, which centralizes the handling of processes and technologies; the other has work to do.

    Also in the issue, columnist Mary Driscoll looks to surveys to figure out who is likely to put financial software in the cloud, Jan Stafford tells why many developers won't be sheepish about Amazon's AWS Lambda and Ed Burns closes with a word of warning: Use security analytics to protect your sensitive data -- or else. Continue Reading
