I am currently involved in a study that focuses on the assessment of the server OS migration market, especially regarding large-scale migrations of mission-critical applications from Sun Solaris to other platforms. It is an interesting time to look at this phenomenon, for obvious reasons.
Our study included questioning a random sample of 2,000 Sr. IT professionals in enterprise-level companies about whether they recently migrated a large workload such as ERP from Sun Solaris to either Windows or Linux. Interestingly, almost 50% of respondents have, with Windows having a lead over Linux as the target platform of choice. We then conducted interviews with some of these respondents to assess the economic (TCO and ROI) and the business benefits of their migrations. In a nutshell, Windows again outperformed Linux in both areas. To get a better picture of the overall market, we spoke with global systems integrators and analysts about their read of the market and the future of Solaris. While the SIs are a little more optimistic about Solaris, the analyst community sees the current uncertainty around Sun as another reason (besides higher TCO) for companies to migrate to other platforms. The server OS market has been already shaken by factors such as dire economic conditions, cloud computing and adoption of virtualization, etc. In the recent recessions, we experienced notable shifts in the OS server market deployments and migrations, the most recent example being the shift away from RISC-based Unix servers and toward x86 server architectures during the 2001-2002 recession. Will the uncertainty around Solaris result in a mass exodus from Solaris to other platforms? If so, which platform will benefit the most?
I will be updating this post as we continue to gather and analyze the data and draw conclusions. Stay tuned…
