saver. So is automated cluster setup. Once you’ve got the server cluster going, you will want to make sure it is healthy – both regarding the health of the cluster as well as the health of the individual nodes that make up the cluster. Keeping on top of problems as they arise brings peace of mind, and substantially improves uptime.
Corral those containers Beyond the basics of clustered infrastructure, your deployment may require more advanced capabilities, such as containers. A container provides a complete runtime environment (application, dependencies, libraries, and configuration files) bundled into one. Tey are similar in many ways to virtual machines (VMs), with the major difference being that the operation system exists outside the container. Tis provides some efficiencies over VMs,
while still solving the problem of how to get soſtware to run reliably when moved from one computing environment to another. You can run multiple containers per server,
reducing the number of servers you need and lowering overall cost. Tis cost saving is driving an increasing number of data centres to deploy containerised architectures in their data centres. Advanced cluster managers may support
containers within clusters by integrating Docker technology. Tis allows users to isolate processes in the cluster from one another and ensure applications run in a consistent environment. Isolating processes in the cluster makes it easier to write secure applications to run in a clustered environment. Te use of containers can ensure that
applications can get at whatever file systems, third-party applications, or other resources they

need, no matter which cluster the application is sent to run on. If your cluster manager also supports Kubernetes orchestration, containers can share resources across the cluster to do things such as load balancing.
Solving your hybrid cloud conundrum An excellent cluster manager is essential when it comes to your organisation’s hybrid cloud setup. Tis is because configuring and managing a hybrid cloud can be very challenging. Balancing resources between on-premise, private cloud, and public cloud requires data centre managers to make some hard decisions about reliability and security. It also requires some sophisticated configuration and management expertise. What can you do if your firm doesn’t have the
requisite experts on staff? Make sure you have an excellent cluster manager at your disposal. Make sure your organisation has the ability to stand up server clusters in a hurry. Make sure cloud bursting is at the ready in case there is a need to call up more services quickly from the public cloud. Make sure you can organise all of your computing resources in a modular fashion so that changes can be made quickly and hassle- free. I’m biased, of course, but I believe you should
give Bright Computing serious consideration when it comes to selecting management soſtware for your hybrid cloud. From a blog by Julia Shih titled 2016: Year of the Monkey (and the Hybrid Cloud), ‘Bright OpenStack works by discovering bare-metal hardware and installing a Linux distribution over the top of it. Tis Linux platform then serves as the foundation for a fully operational OpenStack cluster, which in turn can provision and manage virtual machines

Do you need cluster management? Any organisation that uses HPC with other cluster-based systems can benefit from using advanced cluster management soſtware. Te ability to repurpose nodes quickly for the task at hand, constantly monitor the entire system for problems, and manage hardware, soſtware, and network components in an integrated fashion is indispensable to a thriving organisation. Automated configuration and deployment
lend agility to organisations, as new systems can be brought online quickly to respond to new business requirements. Constant monitoring of systems ensures that
every component within a cluster is tracked for performance and availability. Such vigilance goes

a long way towards spotting problems early so that you can intervene, correct the issue, and keep the workloads running. On-demand and cluster extension into the
cloud enable a dynamic, responsive data centre to cater to the needs of a modern enterprise. No more bottlenecks. A capable cluster manager can take the
grunt work out of building and maintaining a clustered infrastructure of any kind. As a result, your researchers are free to pursue their main objective instead of acting as ad-hoc systems administrators. And your systems administrators can get more work done in less time, making your entire organisation more efficient. l
