With the introduction of the Sitecore 8.2, Sitecore also introduced some Sitecore web deployment packages (WDP), which are used by the Sitecore-Azure-Quickstart-Templates for the deployment of Sitecore. When using ARM templates to provision the Sitecore Infrastructure and deploy the Sitecore application, this works fabulously. But when there is a requirement to use the VSTS Azure App Service deployment task, these packages can’t be used, due to two reasons. This blogpost explains why this task can’t be used and how to fix it (and explains why I spend a lot of time on writing a custom deployment script)
Sitecore released a nice Installation framework to install Sitecore, xConnect and configure Solr. I used this framework already a few times (on a few machines and it turned out that I am very proficient in breaking things. Especially Sitecore 9). During this installation I faced some inconvenient issues (and found out some tips) which I wanted to share with you. This should help you getting up and running even faster!
Today I experienced an error while installing Sitecore 9 using the Sitecore installation framework:
“Install-SitecoreConfiguration : Error CREATEing SolrCore ‘xp0_xdb’: Unable to create core [xp0_xdb] Caused by: null”
Setting the verbose logging option didn’t help and my tries to manually reproduce the issue didn’t work out as well; Or the core was successfully created or I got an error message that the core was already created.
From a business perspective, downtime is not desirable, ever. And if possible, you want to deploy as often as possible, even multiple times a day Maybe even 50 times a day for complex multi-instance environments. And if there would be any downtime, that should be during nights, as most visitors would be asleep at that time. From a technical perspective, deployments should occur during business hours: all the developers and administrators are working during these hours, thus issues (if any) could be resolved as every engineer would be available.
We all know about this story, but how many organizations really implement this scenario? This blogpost will show what challenges exist when deploying web applications and how easy it is to implement zero downtime for Sitecore on Azure. The move to Azure not only opens up opportunities for automatic scaling (please make sure to watch his video as well!), but also offers possibilities for enhanced continuity! This blog post does not show off how to integrate with Visual Studio Team Services and Microsoft Release Manager, that will probably be a future topic. Don’t want to read? Watch this video!
Let’s face it: a lot of customers won’t deploy to Azure immediately, but will have a migration to Azure on their roadmap for the next year. It’s wise prepare as much as possible to make the transition smooth. This blogpost shows off how what the differences between the current Azure and classic on-premises are and how to create custom web deploy packages for your on premise environments, to be in line with a possible future upgrade to Azure. It will make your local deployments repeatable while making use of Microsoft standards. Additional advantage: Your (initial) deployments may happen faster!
See the video below where I explained what I did
In my previous blogpost I described how the Sitecore Azure Toolkit works and how to create web deploy packages. In this this blogpost I’ll explain how to create your own web deploy package configurations which can be used on Azure and on-premises, even with Sitecore versions older than Sitecore 8.2 update 1. You can apply role specific configurations, or add custom modules like Coveo, PowerShell Extensions, Unicorn, or even one you package up. Using these techniques will help you establish a repeatable process with standard tooling leading to decreased deployment time. How cool would it be to have Continuous Delivery and Deployment all the way to production?! I’ll demonstrate in an example, Sitecore PowerShell Extensions, how to work towards a continuous delivery process. As a bonus I’ll package Unicorn as well – future posts will depend on this example so why not tackle them now.

With the release of 8.2 Update 1, Sitecore also introduced support for Azure Web Apps. This release is, in my opinion, a major step for Sitecore as this update makes it very convenient to deploy to Azure using the Azure Marketplace or the provided PowerShell scripts, that’s why I think that this release is even bigger than Sitecore 8.2 initial. This deployment pattern is an interesting pattern to use on premise as well, although not all of the services can or should be used on premise. This blogpost describes how the Sitecore Azure Toolkit works. My next blogpost will describe how to use this toolkit to create your own custom web deployment packages, both for Azure and your on premise installation, with even older versions than Sitecore 8.2
Note: be careful when deploying to your own Azure subscription: when managed incorrectly, a Sitecore deployment on Azure can cause Azure to provision an extensively scaled environment, which generates many resources. Be careful as the cost of this could be high.
Update: modified the blogpost slightly thanks to excellent feedback from Rob Habraken, Steve McGill and Michael West. Thanks guys!
