Anthos lets you build, deploy, and manage applications anywhere in a secure, steady manner. The Anthos platform provides a consistent development and operations experience across all your deployments while reducing operational overhead and improving developer productivity. It is designed to allow users to run applications on-premise not just in Google Cloud, but also with other providers such as Amazon Web Service (AWS) and Microsoft Azure.
Anthos is basically a service for Hybrid Cloud and workload management that runs on the Google Kubernetes Engine (GKE) and apart from the Google Cloud Platform (GCP), you will be able to manage workloads running on third-party clouds like AWS and Azure. This simply means now you can enjoy the Cloud you like for your application distribution and management needs. Your admins and developers are not required to learn all the new APIs and environments functionalities that come with a new Cloud, but only Google’s. Based on the Cloud Services Platform that was announced last year, Google is making Anthos’ Hybrid Cloud functionality generally available for GCP with GKE and on data centers with GKE on-prem. Anthos can now cooperate with third-party Cloud services providers including Google’s mighty competitors, AWS and Azure. Google has developed Anthos to modernize applications by containerizing legacy applications. It has enhanced the overall security of on-premise as well as cloud infrastructures. Anthos is fully equipped to manage hybrid Clouds.
Let’s see what are the actual building blocks that are making Anthos an exciting prospect for developers and administrators
Google Kubernetes Engine
Google Kubernetes Engine is the heart of Anthos. GKE supervises most of the critical and time-consuming activities in an efficient way, such as managing clusters and dependent applications, monitoring applications and fixing most of the flaws, switching applications between on-Prem and Cloud. GKE allows you to authorize using your Google account and reserve IP addresses using Google Cloud VPN. You can allocate RAM and ROM for a cluster and it can also scale the deployment up or down depending on the memory demands. Stackdriver Logging and Stackdriver Monitoring facilitate gaining actionable insights into application functionality. It carries the Docker Container format that integrates namespaces, control groups, and UnionFS. Google Site Reliability Engineers ensure the availableness of a cluster whenever required. It runs on Container-Optimized OS that is specially designed for Kubernetes. It also has an inbuilt dashboard that manages resources.
GKE On-Prem is mainly designed and developed for on-premise deployments and with the Cloud Console, you can manage your on-premise clusters. It allows you to integrate the benefits that Kubernetes provides for Cloud environments into your data center. Google will take care of the K8s version upgrades and security patches. It removes the need for VPNs while connecting co-prem clusters to the GCP. Cloud Identity controls cluster access, whereas the GCP Console offers a dashboard that can be used to manage resources. Stackdriver Logging and Stackdriver Monitoring can be implemented to evaluate the cluster considering various parameters.
It’s important to note that GKE On-Prem runs as a virtual appliance on top of VMware vSphere 6.5. The support for other hypervisors, such as Hyper-V and KVM, is a work in progress we might hear back on this soon.
Anthos Config Management
If you are working with multiple Kubernetes deployments across environments, Anthos config management will be a key tool for you. With Anthos Config Management you can request configuration and maintain multiple clusters at the same time. It allows rapid app development across hybrid container environments. A central Git repository manages access & policy controls and ensures efficient enforcement. It also provides top-class security to developers through a consistent environment. It is well-equipped to manage multiple clusters simultaneously using Kubernetes configuration formats including YAML and JSON. In Anthos Config Management, different quota levels can be allocated to staging and production resources. This simplifies the process of configuring policies for cluster groups.
GKE Hub is a networking unit of Anthos. With GKE Hub, you can club GKE on-premise clusters with Google Cloud Services Platform through its GCP console. Kubernetes cluster and workload-related data can be viewed from your GKE dashboards. The GKE hub lets you access this data from the Google Cloud Services Platform. Moreover, it will provide insights from this data and manage your cluster accordingly.
Istio is a service mesh connecting all the components like database, GCP, and other third-party Clouds. IT is primarily used to create clusters with ease and can also be used on an existing cluster. It is responsible for the management of microservices through load balancing, traffic management, cluster monitoring, and communication. It gives you visibility into service behavior to get a better idea about its performance along with insights into the application. It empowers the user with capabilities like setting up circuit breakers, timeouts, retries, and traffic splits. It is also accompanied by active & passive health checks and rapid failure recovery.
Benefits of Google Anthos
- Anthos gives you a steady platform for all your application deployments, both legacy and Cloud-native while offering a service-centric view of all your environments.
- By decoupling the apps from the underlying infrastructure, the platform gives you the flexibility to run your services across multiple Clouds, on-premises, and even edge locations.
- Build enterprise-grade containerized applications faster with managed Kubernetes on both Cloud and on-premises environments.
- Create a fast and scalable software delivery pipeline across your deployments with Cloud-native tooling and expert guidance.
- Leverage a programmatic, outcome-focused approach to managing policies for your apps running on both VMs and containers. With Anthos, enable greater application awareness and control with a single pane of glass view for your services’ health and performance.
- Protect your software supply chain by applying deploy-time security that controls to ensure that you deploy only trusted container images. Realize immediate operational cost savings by automatically migrating traditional application workloads running in VMs into containers that can be easily added to your CI/CD pipeline.
- Anthos can run directly on bare metal with no third-party hypervisor, transferring better performance while eliminating licensing costs.
Google Anthos helps to make your workforce well-versed with Kubernetes, GCP environments, and other Google applications to make the most out of Anthos. The Anthos modernize your existing applications and run them anywhere. Migrating to open-source-based frameworks can help to wipe out licensing costs and reduce operational overhead. you will be able to manage workloads running on third-party clouds like AWS and Azure. This simply means now you can enjoy the Cloud the way you want for your application deployment and management needs.
