Today at the KubeCon + CloudNativeCon 2017 conference in Austin, TX, the Oracle Container Native Application Development team open sourced two new Kubernetes related projects which we are also demoing here at the show. First, we have open sourced an Fn Installer for Kubernetes. Fn is an open source serverless project announced this October at Oracle OpenWorld. This Helm Chart for Fn enables organizations to easily install and run Fn on any Kubernetes deployment including on top of the new Oracle managed Kubernetes service Oracle Container Engine (OCE).
Second, we have open sourced Global Multi-Cluster Management, a new set of distributed cluster management features for Kubernetes federation that intelligently manages highly distributed applications – “planet-scale” if you will - that are multi-region, hybrid, or even multi-cloud. In a federated world, many operational challenges emerge - imagine how you would manage and auto-scale global applications or deploy spot clusters on-demand. For more info, make sure to check out the Multi-Cluster Ops in a Hybrid World session by Kire Filipovski and Vitaliy Zinchenko on Thursday December 7 at 3:50pm!
Pushing Ahead: Keep it Open, Integrated and Enterprise-Grade
Customers are seeking an open, cloud-neutral, and community-driven container-native technology stack that avoids cloud lock-In and allows them to run the same stack in the public cloud as they run locally. This was our vision when we launched the Container Native Application Development Platform at Oracle OpenWorld 2017 in October.
Since then Oracle Container Engine was in the first wave of Certified Kubernetes platforms announced in November 2017, helping developers and dev teams be confident that there is consistency and portability amongst products and implementations.
So, the community is now looking for the same assurances from their serverless technology choice: make it open and built in a consistent way to match the rest of their cloud native stack. In other words, make it open and on top of Kubernetes. And if the promise of an open-source based solution is to avoid cloud lock-in, the next logical request is to make it easy for DevOps teams to operate across clouds or in a hybrid mode. This lines up with the three major “asks” we hear from customers, development teams and enterprises: their container native platform must be open, integrated, and enterprise-grade:
Both the Fn project and Global Multi-Cluster Management are cloud neutral and open source. Doubling down on open, the Fn Helm Chart enables the open serverless project (Fn) to run on the leading open container orchestration platform (Kubernetes). (Sure beats closed on closed!) The Helm Chart deploys a fully functioning cluster of Fn github.com/fnproject/fn on a Kubernetes cluster using the Helm helm.sh/ package manager.
Delivering on the promise of an integrated platform, both the Fn Installer Helm Charts and Global Multi-Cluster Management are built to run on top of Kubernetes and thus integrate natively into Oracle’s Container Native Platform. While having one of everything works in a Home Depot or Costco, it’s no way to create an integrated, effortless application developer experience – especially at scale across hundreds if not thousands of developers across an organization. Both the Fn installer and Global Multi-Cluster Management will be available on top of OCE, our managed Kubernetes service
With the ability to deploy Fn to an enterprise-grade Kubernetes service such as Oracle Container Engine you can run serverless on a highly-available and secure backend platform. Furthermore, Global Multi-Cluster Management extends the enterprise platform to multiple clusters and clouds and delivers on the enterprise desire for better utilization and capacity management.
Production operations for large distributed systems is hard enough in a single cloud or on-prem, but becomes even more complex with federated deployments – such as multiple clusters applied across multi-regions, hybrid (cloud/on-prem), and multi-cloud scenarios. So, in these situations, DevOps teams need to deploy and auto-scale global applications or spot clusters on-demand and enable cloud migrations and hybrid scenarios.
With Great Power Comes Great Responsibility (and Complexity)
So, with the power of Kubernetes federation comes great responsibility and new complexities: how to deal with challenge of applying application-aware decision logic to container native deployments. Thorny business and operational issues could include cost, regional affinity, performance, quality of service, and compliance. When DevOps teams are faced with managing multiple Kubernetes deployments they can also struggle with multiple cluster profiles, deployed on a mix of on-prem and public cloud environments. These are basic DevOps question that are hard questions to answer:
The three open source components that make up Global Multi-Cluster Management are: (1) Navarkos (which means Admiral in Greek) enables a Kubernetes federated deployment to automatically manage multi-cluster infrastructure and manage clusters in response to federated Kubernetes application deployments; (2) Cluster Manager provides lifecycle management for Kubernetes clusters using a Kubernetes federation backend; and (3) the Federated Ingress Controller is an alternative implementation of federated ingress using external DNS.
Global Multi-Cluster Management works with Kubernetes federation to solve these problems in several ways:
Global Multi-Cluster Management ensures that all of the Kubernetes clusters are created, sized and destroyed only when there is a need for them based on the requested application deployments. If there are no application deployments, then there are no clusters. As DevOps teams deploy various applications to a federated environment, then Global Multi-Cluster Management makes intelligent decisions if any clusters should be created, how many of them, and where. At any point in time the live clusters are in tune with the current demand for applications, and the Kubernetes infrastructure becomes more application and operationally aware.
