Why should Enterprises use Linux?

Why should Enterprises use Linux?

1. Linux has much lower cost as it runs on low cost commodity hardware

Low cost x86 commodity hardware has huge performance and offers much lower costs than propitiatory hardware. For details see:

http://www.spec.org/

http://www.tpc.org/

Example:

	HP c7000 with 16 x BL460 G8	IBM Power 770
CPU cores	16 x 16 = 256	26
Memory	16 x 144GB = 2304	512GB
Performance, SPECintrate2006	16 x 662 = 10,592	942
Price	est $200K	$452K (approx)
COD	None	18 cores/512GB, cost: $10K for 1 core/16GB
Price difference		2.3 x more expensive
Performance difference	11.2 x faster
Price /performance difference	25.7 x better price performance

The above shows commodity x86 servers have much better price performance than propitiatory platforms. Please note the above shows IBM hardware, yet proprietary hardware from HP, Oracle, etc is also significantly more expensive than commodity hardware.

2. All leading internet companies and startups use Linux:

                                                            

These organisation have several orders of magnitude higher transitions volumes than the typical large enterprises and require high level of security and redundancy.

2. All leading public cloud infrastructure provider support Linux:

                                               

To be able to use leading cloud providers proprietary operating system such as Solaris, AIX, HP-UX, OpenVMS, IBM i/OS, IBM z/OS or any other proprietary can not be used. So if you consider that in the future you may  want to migrate workload into the cloud your choices are:

• Linux
• Windows Server

Most public cloud platforms are built on Linux.

3. Over 80% of all Stock Exchanges run on Linux:

                             

If the largest stock exchanges trust Linux why do enterprise IT shops still run propitiatory operating systems on expensive hardware?

4. Smart organisations choose Linux because it offers better price/performance

• Virtually all internet startups use Linux
• Virtually all Public Cloud is built on Linux
• Virtually all Big Data is built on Linux
• US Department of Defense is has huge Linux infrastructure
• Largest retailer Amazon is built on Linux
• Largest enterprise software company Oracle run Linux internally

5.  Over 95% of Top 500 Supercomputers run Linux

6. Linux is well support by application vendors

Today ISVs (Independant Software Vendors) can not ignore Linux, hence all the common enterprise applications are available on Linux including software from Oracle, SAP, IBM, HP, SAS, Symantec, CA, BMC, Quest.

Since Linux is so low cost and easy to deploy many software companies are using Linux as their primary development platform.

7. Linux is the most widely used operating system today

Every Android device (mobile phone, tablet, camera, etc) runs Linux, close to a billion devices as of June 2013:
