3 Agenda Load Balancing Today s Web Application - Benefits of Traffic Management - Introduction to ACE - Design Considerations - Probes, Persistence, Predictors - Resources - SSL Linking VMware VCenter manager to the ANM 5.1 Deploying VMware View w/cisco ACE - VMware View 4.0 Microsoft Deployments - ACE for Microsoft Exchange ACE for Microsoft SharePoint

4 Load Balancing Today s Web Applications What are the challenges? Virtual Data Center introduces new challenges for load balancers and application management - Transition to Virtual Machines (VMs) using Vmware and Microsoft Hyper-V technology - Servers that used to be stand-alone are now VMs - Virtual data center requires orchestration of the application, VM server and switching infrastructure Application Network Manager (5.1) 4

5 Application Delivery Controller Benefits of Traffic Management - Why application delivery Controller: - Availability - Scalability - Performance - Security Mobile phone Web browser Outlook (remote user) Virtual IP ACE Load Balancer Outlook (local user) Client Access Server farm The Cisco Application Control Engine (ACE) provides validated solutions for Microsoft applications Cisco ACE Gbps Cisco ACE30 Module 4 16 Gbps 5

6 Design Considerations One Armed Load Balancer not inline Allows direct server access Requires Source NAT Routed Mode Easy to deploy Requires at least two IP subnets Servers in dedicated IP subnet Bridged Mode Easy migration for servers Requires one IP subnets Recommend for non-lb traffic 6

7 Introduction to ACE Load Balancer Cisco ACE provides many advanced load balancing feature which can be applied to meet challengers with deploying today's applications These features include: 1. Access-control (permit or deny a request) 2. Management traffic 3. TCP normalization/connection parameters 4. Server load balancing 5. Fix-ups/application inspection 6. Source NAT 7. Destination NAT 7

8 Virtual Context Setup Virtual contexts are virtualized ACEs. Each virtual context has independent configuration and dedicated resources assigned. One context can pull resources from another Microsoft Exchange 2010 Cisco UCS Microsoft SharePoint 2010 Virtual Virtualization of Microsoft Exchange 2010 A separate virtual machine for each of the roles: Two Client Access Server, Hub Transport, Four Mailbox in a DAG (Database Availability Group) 8

9 Basic Load Balancing for ERP Applications Is the server active? How can you check? Probes Predictors How can you balance the connections? How do you keep the client connected to the same server? Persistence 9

10 Health Probes SAP Enterprise Portal Configuration 10

11 Health Checks Watch the expected status code ACE/dc# telnet Trying Connected to Escape character is '^]'. GET /nwa HTTP/1.1 Host: NetWeaver Web Administrator HTTP/ Found server: SAP NetWeaver / AS Java 7.1 content-type: text/html location: navigation~wd/nwaapp 11

12 Probe Defaults Name Description Min Time Max Time Interval Time between successful probes FailDetect PassDetect Interval Number of failed probes before marking as failed Time to send a probe when a server is marked as failed Default PassDetect Count Number of successful probes before marking the server as passed Open time for a successful 3-way handshake Receive time for getting a response, ie. send a GET, wait for a reply

13 Probe Configuration Options To configure a real server to remain in the OPERATIONAL state unless all probes associated with it fail (AND logic), use the fail-on-all command in real server host configuration mode probe http BasicHTTP_02-probe-1 interval 5 passdetect interval 5 request method get url /index.html expect status open 10 probe scripted SQL_USER interval 5 passdetect interval 10 script SQL_PROBE SQL_User Success 0! serverfarm host BasicHTTP_02 failaction purge probe BasicHTTP_02-probe-1 probe SQL_USER rserver rserver rserver

14 Predictors - Application Response Load balancing based on server response time; response time calculated over a configured number of samples and supports the following options ACE Serverfarm SYN to SYN-ACK Time between SYN send from ACE to SYN-ACK received from the server SYN to Close Time between SYN send from ACE to FIN/RST received from the server Application Request to Response Time between HTTP request send from ACE to HTTP response received from the server 14

15 Predictors - Application Response Measures the response time from when the ACE sends an HTTP request to a server to the time that the ACE receives a response from the server for that request serverfarm TCP80-SF predictor response app-req-to-resp rserver SERVER1 rserver SERVER connections real weight state current total failures rserver: TCP80-SF :0 8 OPERATIONAL max-conns : -, out-of-rotation count : - min-conns : - conn-rate-limit : -, out-of-rotation count : - bandwidth-rate-limit : -, out-of-rotation count : - retcode out-of-rotation count : - average response time (usecs) :

16 Session Persistence When customers visits an e-commerce site, they usually start out by browsing the site Depending on the application, the site may require that the client become "stuck" to one server once the connection is established, or the application may not require this until the client starts to build a shopping cart This is known as stickiness or session persistence Prior to ACE 4.X, sticky connections require a resource class to be configured. If your forget ANM will send you the following message 16

23 Allocation of Resources

24 Virtual Context Setup Every ACE device contains a special virtual context called "Admin", which has settings for the ACE device itself. You can configure load balancing within the Admin context, it is recommended that you create separate virtual contexts for load balancing The capacity of each ACE virtual context is determined by its resource class If Admin context is not configured correctly admin could be starved of all resources When configuring resource allocations in ACE, it is possible to allocate 100% of resources to non-admin contexts, so that the Admin context is no longer reachable via ICMP, telnet, SNMP, etc 24

25 Recommended Settings for Admin Context resource-class ADMIN limit-resource conc-connections minimum 5.00 maximum equal-to-min limit-resource mgmt-connections minimum 5.00 maximum equal-to-min limit-resource rate bandwidth minimum 5.00 maximum equal-to-min limit-resource rate ssl-connections minimum 5.00 maximum equal-to-min limit-resource rate mgmt-traffic minimum 5.00 maximum equal-to-min limit-resource rate conc-connections minimum 5.00 maximum equal-to-min! resource-class STICKY limit-resource all minimum 1.00 maximum unlimited limit-resource acl-memory minimum 5.00 maximum equal-to-min limit-resource conc-connections minimum 5.00 maximum equal-to-min limit-resource rate bandwidth minimum 5.00 maximum equal-to-min limit-resource rate connections minimum 5.00 maximum equal-to-min limit-resource sticky minimum 6.00 maximum equal-to-min limit-resource rate ssl-connections minimum 5.00 maximum equal-to-min 25

26 Considerations when Load Balancing SSL Connections

27 SSL Server Offload To terminate or initiate HTTPS connections with ACE, the virtual context must have at least one SSL proxy service. An SSL proxy contains the certificate and key information needed to terminate HTTPS connections from the client or initiate them to the servers ANM (Application Network Manager) provides you with a guided setup to import an SSL key pair into the ACE 27

28 Sample SSL Key/Cert Pair ACE shipped with a default RSA 1024 bit. Certificate is based on this key pair The sample certificate and key are named cisco-sample-cert and ciscosample-key You can view the sample SSL key and cert The sample SSL key and cert files can be exported using the crypto export command 28

29 Basic SSL Load Balancing Redirecting Clients to Use SSL rserver redirect REDIRECT webhost-redirection %h %p! serverfarm redirect REDIRECT-SF rserver REDIRECT! class-map match-all HTTP 2 match virtual-address tcp eq 80! policy-map type loadbalance first-match REDIRECT-PM class class-default serverfarm REDIRECT-SF! policy-map multi-match LOADBALANCE class HTTP loadbalance vip loadbalance policy REDIRECT-PM 29

30 SSL Server Offload Configuration In order to configure SSL, you need to add the following to a L3 / L4 class map: - parameter-map type ssl - ssl-proxy service - policy-map parameter-map is used to define parameters for SSL connections (e.g., SSL version, cipher suites, close protocol behavior) ssl-proxy is used to define the used certificates and keys to be in SSL connections 30

38 Deploying VMware View 4.0 with Cisco ACE

39 Why add a Cisco ACE? Scalability: Larger deployments require multiple Security Servers or multiple Connection Servers - Cisco ACE balances client connections across available connection servers - VMware rates a single View Connection Server at 1,500 concurrent non-tunneled connections, and 30% less if tunneled Fault Tolerance - Cisco ACE detects the failure of View components, and directs traffic around the failure Performance - Reduce CPU usage on Connection Servers by offloading HTTPS cryptography 39

40 VMware View deployment with Cisco ACE General Types of View Deployments LAN Direct Deployment - Display protocol does not pass through the View Connection Server LAN Tunneled Deployment - Display protocol Traffic is encapsulated in HTTPS and passes through the View Connection Server Secure (DMZ) Tunneled Deployment - Display protocol Traffic is encapsulated in HTTPS and passes through the View Security Server - View Security Server does not participate in Active Directory, and can be safely placed in DMZ 40

41 VMware View deployment with Cisco ACE LAN Tunneled Deployment w/ace 1. Authentication 2a. RDP 2b. RDP Decrypted 2c. RDP Brokered Cisco ACE Connection Servers View Client ESX Cluster Containing Virtual Desktops More Secure All traffic encapsulated in SSL. Virtual Desktop IP Addresses do not need to be reachable by clients Offload Benefit SSL cryptography offloaded by Cisco ACE, reducing CPU utilization on Connection Servers Recommended for LAN deployments on secure networks. Connection Servers participate in Active Directory and should not be exposed to the Internet 41

52 Outlook Anywhere Over HTTP If ACE can use the User-Agent: MSRPC HTTP header to detect RPC over HTTP This enables you to use the same VIP for OWA and Outlook Anywhere, therefore saving address space ACE can use the Basic Authorization header for session persistence. This eliminates you having to use SOURCE-IP stickiness RPC_IN_DATA /rpc/rpcproxy.dll?exch-ace-tme.com:6004 HTTP/1.1 Accept: application/rpc User-Agent: MSRPC Host: exch-ace-tme.com Content-Length: Connection: Keep-Alive Cache-Control: no-cache Pragma: no-cache Authorization: Basic Q0xJRU5UXG1kaXR0bWVyOmZvbw== When using NTLM it is believed the hash value could change. Therefore you cannot use the Authorization header for session persistence. You will need to use source-ip stickiness 53

60 Microsoft SharePoint 2010 with ACE

61 What Is Microsoft SharePoint Server 2010? Microsoft SharePoint Server 2010 is a portal-based collaboration platform for creating, managing and sharing documents and Web services SharePoint 2010 enables users to create "Sharepoint Portals" that include shared workspaces, applications, blogs, wikis and other documents accessible through a Web browser 62

62 Logical Architecture A SharePoint 2010 Serverfarm is a 3 Tier Architecture, which consists of: Web Front End Server(s) Application Server(s) Database Server(s) The Web Server role provides Web content to clients. The Application Server role provides SharePoint 2010 services such as search queries, Office Web Applications and crawling and indexing content The Database Server stores Content and Configuration information. Browser Config DB SharePoint Web Front End Client App SharePoint Application Server Content DB Custom DB 63

63 Minimum Requirements for a SharePoint 2010 Installation The following components are required for a minimum installation of SharePoint 2010: SharePoint Server 2010 (This is 64-bit only) 64-bit Windows Server 2008 SP2 or 64-bit Windows Server 2008 R2 64-bit SQL Server 2008 or 64-bit SQL Server 2005 SQL 2005 x64 SP3 CU3 SQL 2008 x64 SP1 CU2 64

64 SharePoint 2010 Topologies SharePoint Server 2010 can be deployed in a serverfarm environment when hosting a large number of sites, when the best possible performance is required, or if the scalability of a multi-tier topology is needed A Serverfarm consists of one or more servers dedicated to running the SharePoint Server 2010 application Serverfarm environments can encompass a wide range of topologies, and can include many servers or as few as two servers Because a Serverfarm deployment of SharePoint Server 2010 can be complex, Microsoft recommends that you plan your deployment 65

65 Large Topology Considerations Although Microsoft Windows 2008 Server can provide software-based load balancing, Cisco ACE can offer higher performance ACE also provides server health monitoring, and TCP connection management and HTTP optimization using HTTP compression and hardware SSL termination Virtualization within ACE allows a single pair to serve multiple SharePoint applications as well as other Microsoft and non-microsoft enterprise applications It is possible to collapse a multi-tier architecture onto a single pair of ACE devices without the need to order and configure additional equipment Microsoft SharePoint 2010 Microsoft Exchange

66 Large Topology Considerations The GSS probes the ACE load balancers to retrieve the Web front-ends health and load information Based on this information the GSS can load balance the users request to the best available data centre The GSS then provides user stickiness for all users sequential request The GSS is authoritative for the WWW. The GSS will only provide a A record if the Web front-ends health is available 67
