Containerization is often the key to a successful migration from on-prem data centers and servers to cloud service platforms such as AWS, Azure, and Google Cloud Platform. By packaging the source code of legacy applications and dependencies, containers are lightweight means of migration of resources. However, the problem kicks in when there are multiple container applications to migrate and manage. This problem is further complicated with the onset of microservices architecture; thus, developers handling large systems will have to overlook hundreds of containers. This is where container orchestration technology proves to be essential.
Docker Swarm and Apache Mesos are examples of tools that create clusters to manage containerized applications. However, Kubernetes, developed by Google in 2015, has become one of the most popular open-source tools for creating clusters for containers.
Today Kubernetes a.k.a K8 has become the popular choice for setting up and deploying cloud-native infrastructure. It allows developers a framework to run distributed systems efficiently through scaling, failovers, and deployment patterns. With Kubernetes, developers can:
No component within Kubernetes holds as much importance as the Kubernetes cluster. What is a Kubernetes cluster? It’s simple: when you deploy K8, you get a cluster. The nodes within this cluster run the container applications. With the help of the control plane, decisions can be made about various events, including cluster scheduling, or starting up a new pod. The following diagram gives a comprehensive overview of its components:

With Anthos, Google Cloud Platform aimed to solve a problem IT departments were facing with the popularity of Kubernetes clusters and control planes: the need for a “meta” control plane for the control planes across all departments. And this control plane needed to have the ability to deploy and manage clusters across environments: on-prem, private/public cloud services platforms, and even hybrid cloud solutions and the same reliability as Google Cloud’s in-house K8 manager: GKE (Google Kubernetes Engine). There are a few crucial pillars for Anthos to function successfully:
Google Cloud Anthos represents a solution for organizations that wish to migrate apps from on-prem or across cloud services platforms. Get directions on how to transfer legacy applications to GKE with Migrate for Anthos and deploy applications from AWS to GCP by downloading our whitepapers.
The key difference between the two is that Google Cloud Anthos is a step up from Kubernetes clusters; it helps manage the problem of multiple clusters. Whether you need Anthos or K8s depends on the number of clusters required to run services smoothly.
Kubernetes is a proper cloud-agnostic solution leader in Docker management. In addition, it possesses autoscaling, and self-healing is quick to set up and is a cost-effective solution. However, several snags are too: it is solely for managing infrastructure (a Container as a Service tool). It, therefore, needs more expertise to manage and poses difficulty for setting up on-prem clusters by itself due to high resource requirements. However, with Google’s Anthos, companies access a service that can enforce uniform policies, upgrades across multiple clusters, enable managed Kubernetes anywhere, and direct access to Google SREs for troubleshooting and remediation. But since it provides managed services, many companies will find the solution too expensive.
Therefore, choosing to upgrade to Google Cloud Anthos will depend on the number of resources and location. Anthos is only viable for organizations with countless clusters spread out across hybrid and multi-cloud environments and is facing difficulty managing these multiple clusters and control planes. In addition, it is required for companies to balance multiple microservices, such as an e-commerce site. In contrast, Kubernetes can be a simple solution for a small company that wishes to create efficient container applications on the same cloud service platform.
In conclusion, while there are operational differences between Anthos and Kubernetes, Anthos is better understood as the next step to managing Kubernetes clusters. These two platforms serve the vital role of building cloud-native infrastructure with minimum disruption. The choice between these two services comes down to the level of management your business needs regarding the desired level of container orchestration.
