Core Concepts, High Availability, Certificate and Share. Point considerations. Print posted on Friday, July 2. AMIntroduction. Theres not a lot of high quality documentation for Workflow Manager 1. What exists is generally accurate, however its the key missing information and lack of detail which presents challenges in the field. Additionally a couple of the critical details are either hidden away in the murky depths of MSDN, or are incorrect due to copy and paste errors. Much of the Tech. Net Share. Point documentation is either wrong, or will only ever work with a single server farm. During the initial content development work for the MCSM Share. Point it became clear there is a very large gap with respect to actually implementing the high level deployment guidance provided by the vendor. Following recent discussions in the MCSM Share. Point community more generally, the topic again raised its head and led to the publication of this article. This guide is an attempt to help address that gap, and if the wider community feels it is of value, will be the first of a number of Workflow Manager related posts in the context of Share. Point 2. 01. 3. The objective is not to cover background conceptual or architectural aspects of Workflow Manager or Service Bus specifically, as these are well covered already elsewhere. Rather the objective is to provide clear and accurate explanation along with repeatable deployment and configuration details for common scenarios faced by the Share. Point practitioner. This article will focus on the deployment and configuration of a highly available, SSL, Workflow Manager Farm for use with Share.

In most test and lab environments a single server Workflow Manager farm is deployed and is sufficient. Pretty much everything you will find will talk to this scenario with scant mention of doing it properly in production. Pretty much all of the deployment guidance on Tech. Net and elsewhere actually uses steps that simply will not work in anything other than a single server Workflow Manager farm, from certificates to user accounts. When it comes to production environments, high availability, performance and throughput and security are paramount. Furthermore it is clear that the SSL aspects of a real Workflow Manager farm are poorly documented and confusing. This article is in four parts, due to its length, and also to avoid switching between exposition and configuration Core Concepts, High Availability, Certificate and Share. Point considerations End to End Configuration using auto generated certificates and NLBSwitching an existing farm to use Domain CA issued certificates. End to End Configuration using Domain CA issued certificates For those comfortable with the technology this first part will be enough. The other two parts will include lots of nice Windows Power. Shell, and some not so nice Windows Power. Shell Lets get started. High Availability versus Scalability. As hopefully you are all aware a Workflow Manager farm sits on top of a Service Bus farm, and can either be a single server, or three servers. There are no other supported topologies. Service Bus reaches a quorum with three nodes. Whilst the background to that is academically interesting, you dont really need to know the why here, although understanding the concept of quorum in general should be considered a software architecture fundamental. Aside from that it just doesnt matter, its one or three. Hi, In eairler versions of0. OS X Server 2. 2 your where able to install a purchased SSl certificate in the. Hardware Profile Manager Server. CUCM Certificate RegenerationRenewal Process Cisco. Introduction. This document provides a recommended, step by step procedure to regenerate certificates used in. Again, nothing else is supported, and thus nothing else matters. In order to deploy a highly available Workflow Manager farm, that of course means we need three machines in our farm. Because Workflow Manager sits on top of Service Bus, we get high availability for free via its scale out model. CallManager-pem.png' alt='Install Certificate Call Manager 8' title='Install Certificate Call Manager 8' />Service Bus takes care of business behind the scenes for us and the correct node will handle tasks. This is automatic and also provides the performance and throughput benefits of a farm deployment. Whilst this article is not focused on topology, with Share. Point 2. 01. 3 the external Workflow Manager Farm deployment should be considered and treated as an appliance, albeit a reasonably complicated one. In other words we should accept the required topology design for vendor supportability, set it up and leave it be. That means three servers, each of them running Service Bus and each of them running Workflow Manager. This is what everyone should be doing for Share. Point 2. 01. 3 On premises deployments. TomcatCertCSRGenerationDownload.JPG' alt='Install Certificate Call Manager 8' title='Install Certificate Call Manager 8' />However this isnt high availability, its horizontal scalability. Its pretty sweet. The trouble is the perception that Service Bus takes care of everything. Which is not the caseWhen we create a connection to a Workflow Manager farm from a Share. Point farm with the Register SPWorkflow. Service cmdlet we pass in a Workflow. Host. Uri parameter. This typically is the host name of a Workflow Manager host. If we have three Workflow Manager hosts, which host name should we use Well we can use anyone we like, as long as its valid. This will work. But its not highly available. If that particular host is down for whatever reason, our Workflow Connection which is a Service Application Proxy will be broken and we cannot configure or execute any Share. Point 2. 01. 3 workflows. Despite being a Service Application Proxy, the external service Workflow Manager does not interact with Share. Points Application Addresses Refresh capability to cache a list of endpoints for Workflow Manager. The solution here is simple. We need to implement some form of load balancing for the Workflow Manager farm so that the consuming Share. Point farms speak to the Workflow Manager farm via a virtual name. We can use Network Load Balancing, Application Request Routing, or if we just want to spend more money than necessary for the sake of it, a hardware solution. The Scaling out Workflow Manager 1. The servers should be configured with a software or hardware load balancer for proper load balancing, or can be accessed directlyThats all very well and good and to be fair implementing load balancing for Workflow Manager, as we will see in part two, is very easy indeed. However instructions are always useful and when we add SSL into the mix it gets a little more interesting. Secure Sockets Layer. Workflow Manager should use Secure Sockets Layer SSL. Period. Sure theres an option in its configuration to allow HTTP connections. Sure theres an option to make a HTTP connection from Share. Point. Sure theres an option to configure Share. Points STS to allow HTTP. However none of those options should be used, and they certainly shouldnt be used in production deployments. Workflow Manager should use SSL. Period. Why Because its a Server to Server S2. S trust, and Server to Server trusts leverage OAuth. OAuth. 2 is an authorization framework, which can at best be described as an insecure authorization framework Without going into that whole saga, a key consideration is that it presents tokens over the wire in plain text. Thus we leverage the Universal Firewall Bypass Protocol UFBP otherwise known as Secure Sockets Layer SSL to protect those tokens over the wire. Using SSL doesnt make OAuth. And thats critical for production environments. SSL certificates are commonly avoided for no good reason, often viewed as scary, expensive or involving another team one that manages the Certificate Authority. Lots of people think that their internal network is secure. These things combined lead many to avoid the use of SSL certificates.
