Dramatic cost optimization that is achieved by Ocean running containerized workloads on spot instances with an enterprise-level SLA for availability.

Immediate scaling for high priority workloads with Ocean’s “headroom”, a customizable buffer of extra CPU and Memory for every cluster, ensuring your important workloads will immediately run whenever needed.

This creates a positive cycle as pods are rightsized, nodes can then be downsized for greater utilization and cost efficiency.

Resource right-sizing that is based on real-time measurement of your pods’ CPU and Memory consumption enabling you to right-size your container requirements for cost-efficient cluster deployments.

Container-level cost allocation and accountability that provides insight into team, project or application costs with drill-down by namespaces, deployments, resources, labels, annotations and other container-related entities.

Additionally, intelligent bin-packing of Pods onto available nodes, drives optimal cluster utilization and cost reduction.

Pod-driven autoscaling that out-of-the-box, takes into consideration Pod requirements, and rapidly spins up (or down), the relevant nodes so your workloads always will have sufficient resources.Some of the key benefits of Ocean include: It continuously monitors and optimizes infrastructure to meet containers’ needs, ensuring the best pricing, lifecycle, performance, and availability. Ocean by Spot is an infrastructure automation and optimization solution for containers in the cloud (working with EKS, GKE, AKS, ECS and other orchestration options). The serverless experience for Kubernetes infrastructure Let’s take a look at a turn-key alternative and then how it supports Spark workloads. auto scaling groups) which might be a heavy burden for some teams. But this requires significant configuration and ongoing management of Cluster-Autoscaler and all associated components (e.g.

Of course one can take a do-it-yourself approach using the open-source Cluster-Autoscaler. With most workloads being quite dynamic, scaling instances up and down will require some form of Kubernetes infrastructure autoscaling. For Kubernetes to manage all the different workloads, Spark or otherwise, it needs some underlying compute infrastructure. While this sounds great, we’re still missing one key ingredient.

Fast cluster spin-up time due to the immediate scaling of containers and Kubernetes.

This reduces the possibility of several workloads racing over the same resources

Each Spark workload gets its own “piece” of infrastructure (which is scaled down when the process ends).

Cluster only runs when needed and shuts down when there’s no workload running.

Only the exact resources needed by the workload/application are used.

In the context of a Spark workload this provides the following advantages: Since Spark 2.3, using Kubernetes has allowed data scientists and engineers to enjoy the many benefits of containers such as portability, consistent performance and faster scaling along with a built-in mechanism for servicing burstable workloads/applications during peaks, scheduling and placement of applications on appropriate nodes, managing applications in a declarative way and more.

In this post, we will be focusing on how to run Apache Spark on Kubernetes without having to handle the nitty-gritty details of infrastructure management. These resources can either be a group of VMs that are configured and installed to act as a Spark cluster or as is becoming increasingly common, use Kubernetes pods that will act as the underlying infrastructure for the Spark cluster. While Spark manages the scheduling and processing needed for big data workloads and applications, it requires resources like vCPUs and memory to run on. As an open-source, distributed, general-purpose cluster-computing framework, Apache Spark is popular for machine learning, data processing, ETL, and data streaming.
