The Next Generation Clusterless Federation Design in the Cloudistics Cloud Platform
Is there another way to manage your VMs? Yes, the introduction of the Cloudistics Cloud Platform has an innovative approach – non-clustered (or clusterless) federated design.The clusterless federation of the Cloudistics Cloud platform uses categories and tags to characterize computer nodes, migration zones, and storage groups (or blocks). With these benefits: ⦁ Node Limits Are A Thing of the Past. ⦁ Locking limitations are removed. ⦁ Flexibility is Enhanced. ⦁ Ladders of Latency are Removed. ⦁

This paper is written in the context of modern virtualized infrastructures, such as VMware or Nutanix. In such systems, a hypervisor runs on each compute node creating multiple virtual machines (VMs) per compute node. A guest OS runs inside each VM.

Data associated with each VM is stored in one or more virtual disks (vDisks). A virtual disk appears like a local disk, but can be mapped to physical storage in many ways as we will discuss.

Virtualized infrastructures use clustering to provide for non-disruptive VM migration between compute nodes, for load balancing across the nodes, for sharing storage, and for high availability and failover. Clustering is well known and has been used to build
computer systems for a long time. However, in the context of virtualized infrastructures, clustering has a number of significant limitations. Specifically, as we explain below, clusters limit scalability, decrease resource efficiency, hurt performance, reduce flexibility and impair manageability.

In this paper, we will present an innovative alternative architecture that does not have these limitations of clustering. We call our new approach clusterless federation and it is the approach used in the Cloudistics platform.

The rest of this paper is organized as follows. In Section 2, we describe the limitations of clustering and in Section 3, we drive the point home by using the specific example of VMware; other virtualized systems are similar. In Section 4, we present the clusterless federated approach and show how it avoids the limitations of clustering. We summarize in Section 5.

Does Deploying Citrix in the Cloud Make Performance Monitoring Easier?
Organizations now have a variety of cloud-based options for delivering virtualized applications and desktops. Cloud deployments are fast, involve lower hardware footprint and simplify IT operations. A key question to answer in this context is whether Citrix Cloud services make performance monitoring easier than it was for on-premises deployments. Read this white paper and find out how to implement monitoring for Citrix Cloud environments.

The technology of cloud computing has caught up with virtual desktop infrastructures. Tapping into the agility and flexibility of cloud-hosted infrastructures, Citrix Cloud enables organizations to simplify digital workspace delivery. With many of the critical components of the Citrix delivery infrastructure hosted in the cloud and managed by Citrix, organizations can speed up deployment, lower hardware footprint, increase ROI, simplify IT operations. Despite the many benefits of Citrix Cloud, the performance management challenges still persist, just as they do in traditional on-premises Citrix deployments.
