Replication Round-up

Whether you use replication as a means of disaster avoidance or disaster recovery, replication of your virtual environment between hot sites has always been a win. With current technology it is even possible to replicate to a replication receiver cloud which could provide a measure of business continuity as well. So who are the players and who provides what service, and how do they do it?

XenApp 6.5: Does Citrix's Latest Release Leave other Vendors up an Iron Cove without a Paddle?

XenApp 6.5 is Citrix’s latest offering of their renowned Presentation Virtualisation (PV) service. Citrix are not alone in updating their feature set.

Why VASA is important to have in your VMware CASA

There are many enhancements and new features that are part of VMware vSphere V5.0 from a storage and I/O perspective (See VMware vSphere v5 and Storage DRS posts). One of those enhancements is a new Application Programming Interface (API) called VASA (vSphere Aware Storage API) which joins other VMware vSphere APIs some of which are shown in table 1. Note that there is a three letter acronym (TLA) shown in table 1 that is part of the VMware vSphere 5.0 release that can be confused with VASA called VSA (VMware Storage Appliance) however for now, let’s leave VSA for a future discussion.

A Look At The Horizon

One of the cool things about attending VMworld every year is seeing what is new on the horizon and this year, ironically, there is something called Project Horizon and the first milestone of that project called VMware Horizon Application Manager. Horizon is a hosted service that will centrally manage the provisioning, access and usage of software-as-a-server (SaaS) applications while at the same time applying the companies standardized security and access controls. This will give the end users of the application the ability to use the applications via VMware ThinApp or View products to stream the application across multiple devices all with a single login. The end users will also have self-service access to a corporate store for their SaaS and Web-based applications. Managing these applications will be completely user based with no need to worry about the underlying device the software or application is running on.

Agent and Agent-less Backup in the Virtual Environment

There is some debate amongst backup vendors on what defines an agent, some consider any amount of scripting to be an agent, while others imply it is what does the data transfer plus any amount of scripting necessary. Is there a need for both Agent and Agent-less within a virtual environment? This also begs the question, who is responsible for properly handling the application whose data you are backing up?
