VMware’s Photon and containers in VMware

4.5/5 (2)

The past month has been categorized as something of a performance and upgrades challenge as one of the constant calls I hear is “application X is going to slow”, of course, a month ago it was fine but today it isn’t and normally this is just down to increasing load.
One of the common fixes for increasing load is to add more vCPU and RAM but often that can cause its own set of problems especially when NUMA boundaries are crossed and when vCPU contention pushes things a little too far.
The second part of the challenge is the upgrade challenge where various applications need upgrading but there are dependency chains to take into account, this is the sort of thing where application X needs a very specific version of application y. In those cases, an upgrade is much easier to do by reinstalling the OS and starting again then transferring the data across!

As a potential solution to these issues that I’ve been exploring is Docker on VMWare’s Photon OS.

docker with microsoft azure

A major force of infrastructure today is the possibility to use CI/CD. Understand, Continuous Integration and Continuous Deployment.

To resume, these technologies, give the possibility to your developers to create/modify their codes, send them to GitHub for example, build it with Visual Studio Team Services (VSTS), save it on you registry (Azure Container Registry for me), manage the versioning, always with VSTS, send it to your Docker Swarm cluster as container et to finish, access it through a simple web interface.

Image2Docker is a tool to convert some Windows Server roles to Docker containers (on Windows, for sure).

With this new version, it’s possible to extract ASP.NET website to run them in containers. To start, I created a VM with 3 ASP.NET websites. This is the view that I have from IIS Manager:
