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.

Citrix is known all over the world for its leading desktop solutions — for good reason: Citrix expertly solves Windows delivery and desktop challenges for customers. In order to make the Citrix desktop experience seamless for end users and desktop administrators, Citrix currently provides basic solutions that solve some longstanding Windows challenges in two key areas – User Profile Management and Application Layering. Liquidware Labs – a Citrix Ready Premier partner – also offers solutions that address the challenges of User Profile Management and Application Layering in Windows desktop environments. Our ProfileUnity solution offers full-featured User Environment Management (which encompasses User Profile Management). FlexApp, which can be integrated with ProfileUnity or used as a stand-alone solution, addresses the area of application layering. This paper initially covers the topics of profile management and user environment management, and then shifts focus to Application Layering. The purpose of this document is to outline the typical uses cases for the Citrix solutions, and then go on to explain when it is more appropriate to utilize the more sophisticated ProfileUnity with FlexApp solution to more completely address gaps in the desktop environment.
Application Lifecycle Management with Stratusphere UX
Enterprises today are faced with many challenges, and among those at the top of the list is the struggle surrounding the design, deployment, management and operations that support desktop applications. The demand for applications is increasing at an exponential rate, and organizations are being forced to consider platforms beyond physical, virtual and cloud-based environments.
Enterprises today are faced with many challenges, and among those at the top of the list is the struggle surrounding the design, deployment, management and operations that support desktop applications. The demand for applications is increasing at an exponential rate, and organizations are being forced to consider platforms beyond physical, virtual and cloud-based environments. Users have come to expect applications to ‘just work’ on whatever device they have on hand. Combined with the notion that for many organizations, workspaces can be a mix of various delivery approaches, it is vital. to better understand application use, as well as information such as versioning, resource consumption and application user experience. This whitepaper defines three major lifecycle stages—analysis, user experience baselining and operationalization―each of which is composed of several crucial steps. The paper also provides practical use examples that will help you create and execute an application-lifecycle methodology using Stratusphere UX from Liquidware.
