Edge Computing Overview


5

Edge & Infrastructure Services

Major component of most IT deployments

Serves as the foundation for network computing environments

Provide connectivity to clients and servers for network resources such as printers, shared storage, e-mail, Internet connectivity, security and more


6

The Network

Oracle DB

Internet

J2EE Server

Mainframe Application Hosting

7

Why the Edge?

Protect Network from intrusions

Enhance Security by enforcing access rights and policies

Provide Remote Workers with secure tunnels into corporate data

Infrastructure

DataCenter


8

Why the Network?

Benefits of Infrastructure Services

Maximize the utilization of costly hardware Centralize information and administration tasks Increase employee collaboration and teamwork Enhance Security by enforcing access rights & policies


9

Web

Open Source Technology is clearly Winning

Although Microsoft still dominates the Client

Open Source Application Server Market next frontier*

Open source environments, as illustrated by the Linux/OOS numbers, are a major market factor:

We also expect to see the use of open source ASSPs running on other operating systems (e.g., UNIX) to grow equally dramatically during the same forecast window.

23% growth for OpenSource App Servers on Linux until 2008

* IDC: Red Hat Application Server: An Example of How Choice Is Evolving in the Middleware Market Dec 2004 Doc #32554


10

DNS

Dan Moore's DNS Survey http://mydns.bboy.net/survey/l

3 out of 4 organizations choose the OSS BIND when installing a DNS server

1 in 4 who don’t and then choose Microsoft tend to be those supporting fewer domains


11

FTP

ProFTPd: An old standard

WuFTPD: Old standard, Not considered secure

PureFTPd: Lightwieght, fast & Secure

Vsftpd: A Very Secure FTP Daemon - Written from Scratch and Fast

HTTP Apache taking over as a download protocol

Look out for Bittorrent, fast distributed downloads


12

File

Samba helped NIX get into Windows Domains

Latest Samba3.0 can act as Windows PDC allowing full replacement of NT4.0

AppleTalk HFS- AppleConnectivity

NCPfs – Novell® Connectivity

NFS, AFS , etc – UNIX connectivity

Linux has the most flexibility of any OS

“Interestingly, IT managers who have deployed Linux with Samba have found that Samba requires less expensive and lower power servers than does the Windows software. Additionally, by using open-source software and Linux, managers can remove the expense of Windows server licenses.” - Tom Adelstien, Linux Journal

Why Make the Switch to Linux?


14

Why Move from UNIX?

Linux has become the reference platform for enterprise databases

Linux hardware costs less, and is more easily maintained hardware

Linux deployments provide IT with more options, more flexibility

Diverse set of applications and technology options

Choice of vendors for software and support

Open Source Code provides “insurance”


15

Edge Services are Becoming a Commodity

Most edge & network services come bundled with operating system or can be downloaded for free

Network appliances becoming mainstream

CALs (Client Access License) are under attack from open source Software

Linux is driving this commoditization, mostly at the expense of RISC UNIX

“Open source will continue its commoditization of the industry. The list of markets hit with credible open source alternatives lengthens. Starting with the Linux operating system, we now have entries in browsers, enterprise relational databases, application servers, email, and search engines, to name a few.” - Worldwide Software 2004-2008 Forecast Summary Aug 2004Doc #31785

Linux vs. UNIXIn a Nutshell

Linux

Lower costs: “UNIXworkloads at Intel prices”

Non-proprietary

Based on UNIX

Huge development &support community

Large and growing open source resource base

Most UNIX apps now available in Linux compatible versions

UNIX

Expensive to license, support

Proprietary

Practical only onRISC-based platforms

UNIX consolidation

Security target

Support


18

Where are the savings?

HardwareUNIX loads are typically run on Linux using commodity class hardware that costs up to 75% LESS than the required UNIX system

Hardware MaintenanceThe move to commodity hardware drives an annual hardware maintenance costs drop of up to 90%

Software License CostsCommercial Linux is not free, but annual software license/maintenance fees are typically up to 60% LESS than the UNIX systems they replace

When Should You Make the Switch to Linux?


20

Three Logical Transition Times

When you replace hardware Consider a side by side deployment

When you renew hardware service agreements Hardware and hardware maintenance are the largest

contributors to IT expense

When you upgrade or replace software Most UNIX applications are now available on Linux
