![]() Create an internal TCP endpoint for memcached to listen on.(From the Package Manager Console, this is just install-package WazMemcachedServer.) This adds the memcached binaries (1.4.5 Windows binaries from Couchbase) and a small helper class for launching them. Use NuGet to install the WazMemcachedServer package.In either case, there are three steps to getting memcached up and running: In a heavy-duty distributed cache, you’ll probably create a dedicated worker role just for caching, but in a lot of web applications, you might simply add memcached to your web role. You can run memcached on any role (web or worker). Big thanks to Mike Sampson from the Channel 9 team for helping with this. The package is based on code that Channel 9 uses. It waits until the instance is accepting connections before trying to use it as a cache server. Importantly, it doesn’t just try to use new Windows Azure instances when they’re first added. This code regularly looks for newly added or removed Windows Azure instances and reconfigures the memcached client automatically. The second goal meant extending Enyim in the form of a custom IServerPool implementation called WindowsAzureServerPool. The first goal is met by basing the solution on the Enyim memcached client, which uses consistent hashing by default. Respond automatically when servers are added to and removed from the cluster (during scaling, upgrades, or failures).Use consistent hashing, which minimizes the disruption of adding and removing servers.The client-side is where a bit of work is done. It just launches memcached, listening on an internal endpoint. The server-side implementation is simple. This isn’t for the faint of heart, but it’s a nice option for people who are already experts in tuning memcached for their particular workload (perhaps changing the minimum space allocated per key). Note that Windows Azure Caching has a fantastic “local cache” option, but that still requires that a remote cache is provisioned, and the local cache is not shared (it’s per-instance).Īnother reason some people choose memcached is so they can hand-tune their cache. For example, you may have spare RAM on your web role instances, and adding memcached to them could give you an in-memory cache without adding any VMs (and thus without adding any cost). One scenario in particular that I think is a great fit for memcached is reusing existing RAM. However, I’ve heard from some customers who would like to use memcached. NET developers who want to easily add a cache to their Windows Azure application. Windows Azure has a built-in distributed cache solution ( Windows Azure Caching), which is a great option for. These make it drop-dead simple to add memcached to a Windows Azure application in a way that takes advantage of Windows Azure’s dynamic scaling, in-place upgrades, and fault tolerance.

Optionally adding nginx and memcache into the mix.Optionally supply new relic key as parameter, to send VM metrics to new relic.!(images/azureResourceExplorer.png"SSH into Drupal VMs") Backlog of Planned Changes ![]() You can use Resource Explorer to see the VMs in the VM scale set. So for VM 0 ssh in to port 50000, for VM 1 ssh to port 50001 and so on. You can ssh into the VMs in the VM scaleset if needed, using the inbound NAT Pool ports on the load balancer.!(images/AccessingDrupalSite.jpg"Access Drupal Site") The Drupal admin user name and password which were entered during the template deployment can be used for logging in as administrator. Access Drupal using the VMSS load balancer fully qualified domain name.SSH ports on the VMs are exposed through the load balancer (NAT ports) Deploys a load balancer in front of the Drupal VM Scaleset, so that the VMs are not directly exposed to the internet.The Template can be configured to use an existing MySQL server, or create a New MySQL server (using the MySQL Replication Template).The Drupal nodes mount the file share, where the settings file and files folder are stored The template also deploys an Azure file share.Maximum and minimum number of Drupal 8 VMs in the scaleset can be configured - each of these uses Ubuntu OS.This template deploys a Drupal 8 installation using a VM scale set.
