Executive Summary Discover how migrating from POWER/AIX to x86/SUSE® Linux Enterprise Server can result in significantly lower hardware and software licensing costs, improved interoperability with best-of-breed products, and freedom from lock-in.

Today, you can run almost all mission-critical back-end database applications on x86/Linux using AMD/Intel multi-core scale-up servers. You can do the same with POWER/AIX. The differences, however, include the higher relative cost to do this with POWER/AIX and the sacrifices in innovation that you will have to make with a proprietary IBM solution.

It is difficult today to name a new technology that Linux and open source is not at the center of for innovation: virtualization, cloud computing, Big Data, etc. All of these technologies are important for modernizing your data center. A proprietary company such as IBM cannot innovate around POWER/AIX alone and keep up with community (open source) innovations around x86/Linux.

Big.Data.is.a.new,.but.focused,.area.for.IBM ..In.the.past.few.years,.the.company.has.acquired.about.a.dozen.companies.engaged.in.Big.Data.analytics.and.processing ...IBM.features.a.number.of.Big.Data.offerings.for.POWER/AIX...including.InfoSphere.Streams,.InfoSphere.Biginsights,.IBM..InfoSphere.Warehouse.and.IBM.Smart.Analytics.System ...IBM.is.making.a.strong.commitment.to.open.source.Big.Data..efforts,.including.Apache.Hadoop ..InfoSphere.Biginsights.is.an..IBM-certified.version.of.Apache.Hadoop .

IBM continues to innovate around POWER/AIX. IBM has worked hard to remain competitive, from a per core performance point of view, with multi-core scale-up AMD/Intel x86-64 servers running Linux. But you pay much higher hardware server and maintenance costs and significantly higher software licensing costs than for x86/SUSE Linux Enterprise Server to run basically the same set of applications.
