Amazon Web Services (AWS) customers typically process vast amounts of data, often in the range of petabytes. In complex enterprise environments where multiple workloads and diverse operational demands are prevalent, organizations often opt for a multi-cluster configuration due to the advantages it provides.
- – In the event of a single cluster failure, multiple clusters remain capable of processing critical workloads, ensuring seamless business continuity.
- Elevated job isolation boosts safety by reducing cross-contamination risks and streamlines regulatory compliance.
- Distributing workload across clusters enables seamless scalability in response to fluctuating demands.
- Kubernetes scheduling latency and community network contention significantly reduce to expedite job execution times.
- You can enjoy straightforward experimentation and cost optimization through workload segmentation into multiple clusters.
Despite the benefits of a multi-cluster setup, one significant drawback is the lack of an intuitive method for distributing workloads and ensuring effective load balancing across multiple clusters, thereby hindering the overall efficiency of the system.
This proposal presents a solution to the problem by introducing a centralized gateway that automates job management and routing in multi-cluster environments, thereby simplifying and streamlining workflows.
Challenges with multi-cluster environments
In a multi-cluster environment, Spark jobs running on Amazon EMR on EKS require submission to distinct clusters from various users. The revised text reads: This structure presents several significant hurdles.
- Shopper preferences dictate replacement of connection sets for each objective grouping.
- Managing individual consumer connections in isolation amplifies complexity and operational strain.
- There is no inherent capability to direct jobs across multiple clusters, hindering the setup, resource distribution, return on investment visibility, and fault tolerance.
- Without load balancing, the system lacks fault tolerance and suffers from reduced availability.
To overcome these hurdles, BPG tackles the complexities head-on by providing a unified platform for submitting Spark jobs at a single level. BPG streamlines job routing to the most suitable Elastic Managed Resource (EMR) on EKS clusters, ensuring efficient load balancing, effortless endpoint management, and enhanced reliability for scalable and resilient operations. For customers with complex Amazon EMR on EKS configurations involving multiple clusters and various dependencies, this guidance proves particularly valuable.
Notwithstanding its significant benefits, the current design of BPG is limited to functioning exclusively with the Spark Kubernetes Operator. Moreover, the applicability of BPG remains unexplored when applied to, and the relevance of its answers is uncertain in environments that utilize.
Resolution overview
Designs an abstraction that packages access to an external system or valuable resource. The valuable resource for handling EMR on EKS clusters utilizing Spark functionality lies within. A gateway serves as a unified entry point to access and utilize this valuable resource. The interaction between any code or connection occurs exclusively through the gateway’s interface. The gateway seamlessly translates the incoming API request into the API format supplied by the relevant resource.
The BPG is a specifically designed gateway that provides a seamless interface to Spark on Kubernetes environments. We summarize key particulars about customers’ underlying Spark configurations on their EKS clusters. The application executes within its dedicated Amazon Elastic Container Service for Kubernetes (EKS) environment, interacting with the Kubernetes Application Programming Interface (API) servers from multiple distinct EKS clusters. Customers submitting software applications to Spark through end-users have those submissions routed by BPG to one of its underlying Amazon Elastic Container Service for Kubernetes (EKS) clusters.
The process for submitting Apache Spark applications using BPG (Batched Pipeline API) for Amazon EMR on Amazon Elastic Kubernetes Service (EKS) involves the following steps:
- When a consumer submits a job to BPG using a consumer-facing interface.
- The BPG parses requests correctly, converting them into customised Resource Definitions (CRDs) that are then submitted to an Amazon Managed Service for Kubernetes (EMR) on Elastic Kubernetes Service (EKS) clusters according to predetermined rules.
- The Spark Kubernetes Operator effectively interprets job specifications and triggers job execution within a cluster.
- The Kubernetes scheduler orchestrates the execution of pods by assigning them suitable nodes for deployment.
The following determines the key characteristics of BPG. You can learn more about BPG on GitHub.
A solution to the limitations identified involves deploying Best Practices for Production (BPG) across several existing Elastic Managed Resources (EMR) on Amazon Kubernetes Service (EKS) clusters, effectively addressing these issues.
