Agenda

• Whats New in the OS.
• Whats Better in the OS.
• What Remains Great in the OS.

4
Microsofts Security Framework
5
Build Better Applications Faster

• Build Better Applications.
• Richest set of distributed application services.
• Built in standards, e.g., XML, SOAP.
• Optimized to scale and distribute.
• Robust and enables robust apps.
• Extended by .NET Enterprise Servers.
• Build Faster.
• Write less code.
• Unified programming model.
• Language independence.

6
64-bit Editions for Itanium

• Complete 64-bit OS
• more virtual address space
• more physical memory.
• Completely interoperable with 32-bit Windows OS.
• Some Features
• 32-bit application support.
• For keyboard speed apps.
• Increased I/O throughput.
• Very FAST floating point.
• No .NET CLR Yet, No VB6 ever.

Holds benchmark records!

Whats New in HTTP Services from IIS

• Windows Server 2003
• Internet Information Servicesis IIS 6.0.

8
IIS 6.0 Enhancements
9
IIS6 Increased Security

• Stack Over-run detection.
• IIS6 compiled with /GS flag.
• Configuration Changes.
• ISAPI CGI Restriction Lists.
• No /scripts directory.
• New ACLs.

IIS6 New Robust Process Model
Worker Process
Worker Process

• Process Isolation
• 1 or more processes talking directly to the
  kernel
• Independent from other processes
• Kernel-mode queuing
• Application Pools
• Web Gardens

IIS 6 Performance And Scalability New Process
Model and caching

• 20,000 pooled applications
• Less than 3,000 with IIS5
• 1,000 isolated apps on 1 box each with its own
  security identity
• Max of 100 with IIS5
• Web Garden support
• Pool of processes thatrun one application.

IIS 6.0 Benefits
14
Whats NewIIS ISAPI Enhancements(Internet
Server Application API)
15
ISAPI Enhancements(Internet Server Application
API)

• ISAPI reliability/manageability.
• Signal IIS of need to recycle processServerSuppor
  tFunction() HSE_REQ_REPORT_UNHEALTHY
• Only in worker process isolation mode.
• Must have process pinging enabled.
• WAS checks during ping operation to see if the
  ISAPI has signaled its unhealthy state.
• Used by the ASP ISAPI extension.
• If too many of its threads enter a blocking
  state, it will signal a recycle.

16
New ISAPI Features(Internet Server Application
API)

• New ISAPI Performance/Scalability.
• HSE_REQ_VECTOR_SEND specifies an arbitrary set
  of buffers/file handles in one client send call.
• FinalSend Flag tells IIS that this send is the
  final send for the response.
• Fast Path for sending data.
• Reduces kernel/user transitions.
• Dynamic caching Flag cache a dynamic request
  response, then serve from the kernel.
• Cache greater than 2GB on x86.

17
Whats NewComponent Services (COM) Enhancements

• Windows Server 2003
• Components Services is COM 1.5.

18
COM 1.5 Enhancements

• Scalability.
• Configurable Isolation Level.
• Application Pooling (like IIS 6 Web Gardens).
• Availability.
• Application Recycling (IIS 6 Process Recycling).
• Applications as NT Services.
• Activation Gates.
• Web Services.
• Manageability.
• Pause/Disable Applications (IIS 6 hold for
  debugging).
• Process Dump.
• Programming Model.
• Alias Components.
• Public/Private Components.
• Process Initialization.
• Services without components.
• Security.
• Use OS provided Role based security.

19
COM 1.5 App. Recycling
CAUTION exclusive access to any resource, e.g.,
a file
20
Interoperability Web Services from COM
21
Extending Past COM Investment

• COM apps become Web Services without changing
  code (Admin UI).
• IT Staff, SysAdmins can build Web Services from
  existing COM Apps!
• COM apps COMponents can calland be called by
  .NET components.
• Runs COM apps better
• Activation/method calls gt 50 faster for InProc
  MTA threading model.
• Greater Scalability with Application Pools.
• Especially valuable for VB6 and other MTA
  components.

22
Whats NewMessage Queuing (MSMQ) Enhancements

• Windows Server 2003
• Message Queuing is MSMQ 3.0.

23
MSMQ Enhancements

• Reliable Internet Messaging
• Messaging over SOAP/HTTP in XML.
• Firewalls and Load Balancing.
• Reliable 1-N Messaging
• Distribution Lists.
• In AD or Client Managed, transactional.
• Reliable Multicast.
• Integrated Triggers.
• MSMQ runs code based on msg. content.
