What is an embedded web server? l Software-only – QNX, Spyglass l Hardware for What is an embedded web server? l Software-only – QNX, Spyglass l Hardware for managing and configuring something else – routers, switches, hubs, printers l Hardware for deploying Intranet services – what we’ll demonstrate today

What is an Intranet appliance? l Systems that – support HTTP, HTML – serve What is an Intranet appliance? l Systems that – support HTTP, HTML – serve up files for browser-enabled clients – and more! l and are used to – host a corporate, workgroup, or small business web site, establishing its identity – provide Internet access and LAN services to corporation, workgroup, small biz, K 12

Kinds of appliances Shared disk, filesystem web server l No-frills web server l – Kinds of appliances Shared disk, filesystem web server l No-frills web server l – basic HTML/HTTP l Advanced web server – CGI, Java support, web-enabled discussion groups, e. Commerce, etc. l Multi-server appliances – web and file server plus email, router, DNS, DHCP, web cache, firewall, gateway

Our Design Goals for Appliances l Plug and play – Attach power, connect to Our Design Goals for Appliances l Plug and play – Attach power, connect to Ethernet and go! l User interface – Should be simple, not overly constrained Access controls for users and groups l Configuration, management via browser l Pre-installed web content, utilities, scripts l – Easy integration of these into published site

General State of Appliances Almost plug and play l User interfaces somewhat limited l General State of Appliances Almost plug and play l User interfaces somewhat limited l Setup of users and groups is tedious l – Not well integrated with NOS access controls l Not ready for certain extranet applications – No SSL, PKI, e. Commerce support l Not for high-performance web serving – Expect to support ~50 users,

What features do you need? Ask yourself, ask your vendor: l Types of network What features do you need? Ask yourself, ask your vendor: l Types of network attachment? l How extensible is the web server? l DHCP, DNS, Mail servers included? l Type of built-in OS, web server software? l How many different ways to upload files? l What other tools are bundled with the box? l Are design, content templates included?

Appliances: Pros l Simplicity over NT & UNIX servers, – esp. for organizations with Appliances: Pros l Simplicity over NT & UNIX servers, – esp. for organizations with little or no OS admin expertise l l Reduced total cost of ownership Can lock down web site easier than with general purpose computing platform server

Appliances: Cons l Can’t find and manage on corporate net – not issue for Appliances: Cons l Can’t find and manage on corporate net – not issue for those that support SMB/CIFS/Apple. Share l l l May need more than browser to manage – telnet, proprietary wizards, Difficult to apply uniform user and group access controls across both appliances and NOS systems How scalable is CPU, storage, network?
