I have not witnessed anything that has created as much buzz in the computing community as the goings on between Oracle and Hewlett-Packard over the past few weeks. Well, perhaps Steve Jobs' health and discussion about succession at Apple, but that was contained to Apple. What is intriguing is that this round of ‘musical chairs’ involves not only HP, but also Oracle, because Ray Lane used to be at Oracle, and SAP, because of course Leo Apotheker used to be CEO at SAP. Initially I wrote ‘software community’ instead of ‘computing community’ in my opening sentence. Microsoft first forced the split between hardware and software with the development of DOS, thereby commoditizing the hardware. It sure feels that we may be on the cusp on another big shift in emphasis to a combination of hardware and applications that will commoditize the operating system. I haven’t yet had time to catch up on the latest Twitter comments, but I had to laugh out loud at a tweet by Dennis Howlett musing over the Oracle MarCom team’s efforts to reign in the barbs that Larry Ellison will throw at SAP and HP. There is some really good comment (and speculation) by Dennis Howlett, Tom Wailgum, and Josh Greenbaum on what the appointment by HP of both Apotheker and Lane could mean. I agree with Dennis Howlett that Leo Apotheker taking the CEO job at HP is worth a comment on its own, but the combined appointment of Ray Lane by HP makes this newsworthy. But I am confused because both Apotheker and Lane are software guys who have been appointed by a hardware company (HP), while a hardware guy, Mark Hurd, has gone to Oracle, which is a software company despite its recent purchase of Sun. Or maybe that should be Oracle was a software company until its recent purchase of Sun and Larry Ellison’s keynotes at Oracle World? Now if Larry Ellison had hired Leo Apotheker instead of Mark Hurd, that would have been interesting. There is also an interesting comment by Ray Lane on what this could mean strategically. Ray muses that HP needs to up their game in terms of a combined software, hardware, and services play, extending beyond Oracle's ‘appliance’ play of software and hardware. In this vein there is also much to comment about HP buying SAP, while Dennis Howlett flips this around to speculate about SAP buying HP. Who knows. All I know is that there has been little that has caused as much stir in the blogosphere and twitter universe concerning the enterprise application market. I am much more comfortable commenting on the space than reporting on the space, but this is too big. I have to report this. There is something going on and only time will tell how it will play out. Will we see what appears to be Ellison’s strategy of combining hardware and software prove to be successful? What does this mean for the likes of Microsoft and SAP? Anyone heard the rumor that Microsoft is getting out of the enterprise application space, that is Dynamics? Microsoft’s moment was when it separated the operating system from the hardware, thereby commoditizing the hardware and dominating the desktop, but from an operating system perspective. Yes, Microsoft has gone on to dominate the desktop application space with Office and Internet Explorer, but it started with the operating system. Are we really seeing the moment when the operating system becomes commoditized by the combination of hardware and business applications? Only time will tell.
