2 Business aspect

Agility is driving developers toward more cloud-native methodologies that focus on microservices architectures and streamlined workflows. Container technologies, like Kubernetes, embody this agile approach and help enable cloud-native transformation.

By unifying IT operations with Kubernetes, organizations realize key benefits like increased reliability, improved security and greater efficiencies with standardized automation. Therefore, Kubernetes infrastructure platforms are adopted by enterprises to deliver:

Cluster Operations

Improved Production and DevOps efficiencies with simplified cluster usage and robust operations

Security Policy & User Management

Consistent security policy enforcement plus advanced user management on any Kubernetes infrastructure

Access to Shared Tools & Services

A high level of reliability with easy, consistent access to a broad set of tools and services

2.1 Business problem

Kubernetes is the leading solution to address edge computing use cases in industry verticals such as manufacturing, transportation, power generation, healthcare, retail and banking. Typical edge systems that leverage Kubernetes to run complex workloads include energy meters, aircraft engines, gas & oil rigs, cruise ships, high-speed trains, retail scanners, wind turbine base stations, internet-connected cars, ATMs and much more.

For such target edge systems, which are often unattended, resource constrained and remote, orchestrating containerized workloads on Kubernetes deployments may seem overbearingly complex.

2.2 Business value

After two years of research and development in June 2020, K3s was donated to the CNCF. The donation is a testament of the commitment to the open source community and their mission to run Kubernetes everywhere.

Perfect for Edge

K3s is a highly available, certified Kubernetes distribution specifically designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances.

Simplified & Secure

K3s is packaged as a tiny, single binary that reduces the dependencies and steps needed to install, run and auto-update a production Kubernetes cluster. For workloads, automated Manifest and Helm Chart managment deployments can be utilized. Also, multiple architectures, like x86_64, ARM64, and ARMv7, are supported with binaries and images available.

Given its extensive Kubernetes capabilities, K3s can also be a suitable choice for:

  • embedded platforms,

  • continuous integration and continuous deployment platforms,

  • branch locations or individual developer deployments, and

  • even core or cloud production instances

Tip
Tip

When K3s is imported and combined with SUSE Rancher, organizations are equipped with an easy, complete and reliable management solution for Kubernetes at the edge.

With this increased consistency of the deployed and managed Kubernetes infrastructure clusters, organizations benefit from an even higher level of the Cloud Native Computing model where each layer only relies upon the API and version of the adjacent layer, such as:

Compute Platform

Utilizing the above software application and technology solutions with the server platforms offered by Cisco Unified Computing System (UCS) brings increased productivity, reduced total cost of ownership, and scalability into your computing realm. Cisco UCS is based upon industry-standard, x86-architecture servers with Cisco innovations and delivers a better balance of CPU, memory, and I/O resources. This balance brings processor power to life with more than 150 world-record-setting benchmark results that demonstrate leadership in application areas including virtualization, cloud computing, enterprise applications, database management systems, enterprise middleware, high-performance computing, and basic CPU integer and floating-point performance metrics.

  • Match servers to workloads - The breadth of the server product line makes the process of matching servers to workloads straightforward, enabling you to achieve the best balance of CPU, memory, I/O, internal disk, and external storage-access resources using the blade, rack, multinode, or storage server form factor that best meets your organization’s data center requirements and preferred purchasing model.

  • Powered by AMD EPYC processors or Intel Xeon Scalable processors

  • Industry-leading bandwidth - Cisco UCS virtual interface cards have dramatically simplified the deployment of servers for specific applications. By making the number and type of I/O devices programmable on demand, enables organizations to deploy and repurpose server I/O configurations without ever touching the hardware.

  • Lower infrastructure cost - Designed for lower infrastructure cost per server, is a choice that makes scaling fast, easy, and inexpensive in comparison to manually configured approaches.

  • Rack server deployment flexibility - Cisco UCS C-Series Rack Servers unique in the industry because they can be integrated with Cisco UCS connectivity and management or used as stand-alone servers

  • Integrated Management Controller (IMC) - Running in the system’s Baseboard Management Controller (BMC), when a Cisco UCS C-Series Rack Servers is integrated into a Cisco UCS domain, the fabric interconnects interface with the IMC to make the server part of a single unified management domain. When a server is used as a standalone server, direct access to the IMC through the servers’s management port allows a range of software tools (including Cisco Intersight) to configure the server through its API.
