What is VMware Photon OS?

Today most vendors are putting a lot of emphasis on “cloud native” applications.  Cloud native applications are geared toward containers and containerized applications.  This makes possible running microservices inside containers with the ability to function in cloud computing environments and even deployed across multiple different clouds.  Microservices are discreet software application services that each run inside of its own container.  If you have installed the latest version of the VMware vSphere appliance (VCSA) or other products such as the vSphere Integrated Containers OVA appliance, you will notice as the VMs boot, they are running Photon OS.  VMware is using the Photon OS at the core of many of its new and updated products and appliances.  What is VMware Photon OS?  How does it tie into the new world of cloud native and containerized applications?

What is VMware Photon OS?

Photon OS is a very lightweight Linux container host that is specifically designed for cloud native applications.  The platform has been optimized for the vSphere environment allowing customers to look beyond their current platforms and start thinking about using distributed applications which utilize containers and containerized applications.  VMware has also made the decision and move to open source the Photon OS project to help encourage development, testing, and other enhancements from their customers and the community.

The development of Photon OS is allowing VMware to support and continue to innovate in the traditional datacenter as well as build and extend the capabilities of vSphere to move beyond the traditional enterprise datacenter into containerized workloads using container technologies.  This allows organizations to utilize a single infrastructure to run both the traditional and containerized workloads in the datacenter using the same tooling and technologies they have grown accustomed to with VMware vSphere.

This means that the other technologies found in VMware’s portfolio are interoperable with the cloud native Photon OS based technologies including VMware NSX, vSAN and others.  When you look at the new VMware vSphere Integrated Containers platform, which is based on Photon OS, you see the strong interoperability and integration at work and the seamless way that VMware is delivering containerized workloads using existing vSphere infrastructure.

VMware Photon OS 1.0 Booting

Highlights of Photon OS:

  • It is optimized for VMware vSphere – Photon has been well tested and validated on VMware vSphere and the Photon OS itself has been highly optimized to run on vsphere at the kernel level
  • It includes strong container support – It incorporates support and compatibility for the leading container technologies to date including Docker and scheduling frameworks like Kubernetes
  • Powerful upgrade features – Even though it is a lightweight platform, it includes package management, yum-compatible tdnf package manager that allows yum package management capabilities.

Related to Project Lightwave?

Project Lightwave is also an open sourced project from VMware that is an enterprise identity and access-management solution.  It comes into play in the realm of security, governance, and compliance problems that organizations have to solve.  It includes the following key features:

  • Lightwave Directory Service – Powerful LDAP v3 directory service that can operate at scale
  • Lightwave Certificate Authority – A certificate authority that is integrated with directory service
  • Lightwave Certificate Store – endpoint certificate store
  • Lightwave Authentication Services – Services that support cloud authentication

When paired with Photon OS, it helps to assure only authorized objects can run in the infrastructure.

Thoughts

VMware is certainly shown it is serious not only about virtual machines but also new technologies moving forward in the world of cloud native applications such as containers.  Hopefully this brief overview of what is VMware Photon OS will help any who have wondered about this new platform if they have seen their new VCSA 6.5 appliance booting Photon OS.  It will be interesting to see where the future leads with this project and others like Project Lightwave.
