Another new technology called containers, such as those used in Kubernetes, also make it simpler to migrate data and applications across environments. Much like virtual machines, containers are decoupled from foundational infrastructure. Each container has an application (or piece of one), along with its runtime dependencies, such as CPU, memory, filesystem, processing space, and more. Because these dependencies are included, the application works the same way every time, regardless of which cloud or operating system it’s on.
“Kubernetes clusters on-prem and in the cloud can be managed in a unified manner. They have fundamentally changed what’s possible,” said Deepak Mohan, research director, infrastructure systems, platforms, and technologies at IDC. “[You get a] common experience and oversight across multiple platforms.”
Nutanix Clusters for AWS and Microsoft Azure takes the cluster concept even further in data centers running hyperconverged infrastructure (HCI).
“Nutanix Clusters allows enterprises to run the entire Nutanix software stack directly on bare metal public cloud infrastructure,” said Madhukar Kumar, VP of Product Marketing at Nutanix.
“The Nutanix stack essentially becomes an application running inside the public cloud platform, and there’s no need for WAN connectivity services, or a new public cloud account, which can result in unwanted operational and data silos.”
IT can create a hybrid cloud “in just a couple clicks,” he said. They can use a single platform to move and manage VMs, applications, and licenses the same way in the public cloud and on-premises. This simplifies the need for a wide range of skill sets because teams can use the same “IT generalist” skills, tools and practices across the entire blended infrastructure.
Achieve Business Goals
True hybrid cloud capabilities empower organizations with the agility to respond quickly to evolving market or customer demands. According to a blog post by Steven Kaplan, VP of Customer Success Finance at Nutanix, deploying clusters can help a company in a variety of beneficial use cases.
Clusters can allow a company to temporarily add capacity via the public cloud when needed through “cloud bursting.” The organization can move workloads to the public cloud when extra capacity is needed, then move them back on-premises later. Clusters also form a bridge to public clouds, enabling a company to move some workloads to benefit from the simplicity, resiliency and scalability of the public cloud. Enterprises can also use Clusters to set up backup nodes in their desired AWS or Nutanix Xi Cloud zone for disaster recovery purposes, according to Kaplan.
With the growing flexibility to move, manage and secure data and applications easily across clouds and on-premises environments, enterprises are poised to experience the promise of true hybrid cloud.
