The Virtualization Practice

Cloud Computing

Cloud Computing focuses upon how to construct, secure, manage, monitor and use public IaaS, PaaS, and SaaS clouds. Major areas of focus include barriers to cloud adoption, progress on the part of cloud vendors in removing those barriers, where the line of responsibility is drawn between the cloud vendor and the customer for each of IaaS, PaaS and SaaS clouds, ...
as well as the management tools that are essential to deploy in the cloud, ensure security in the cloud and ensure the performance of applications running in the cloud. Covered vendors include Amazon, VMware, AFORE, CloudSidekick, CloudPhysics, ElasticBox, Hotlink, New Relic, Prelert, Puppet Labs and Virtustream.

Virtualizing Tier 1 business critical applications is a challenge for many enterprises due to the resistance to the concept on the part of applications owners and their constituents. Service Assurance for these applications is required in order for their owners and their users to go along with virtualization. Service Assurance requires the integration of Applications Performance Management, Configuration Management and a new category of solutions like VMTurbo to dynamically allocate resources based upon their highest and best use.

Many of us have to demo virtualization technologies to our customers and colleagues, run classes, develop code for virtualization, or just play around. For many of these cases, a cloud based virtual environment may be fine. However, what do you do when the network connection to the cloud is flaky at best? You have to rely upon your local system to do the job for you. Some solve this problem by having a ready slide deck, others solve this problem by using a fairly high end laptop, and still others tether their laptops to their phones and other cell phone cards. Which method is best?

I have always found local access to my laptop has always been the better way to run demos, classes, and presentations for my customers, colleagues, and friends. As I write software for and books about virtualized environments I almost always need access to various virtualization systems. Where I can I use network connections as going back to the office lab is in most cases much faster than local, but when I have to run things local due to telecommunication issues a high end laptop is a requirement. But which one?

A new Applications Performance Management opportunity has arisen driving by virtualization, the cloud, scaled out deployment architectures, lower cost open source middleware, and agile development techniques. AppDynamics has raised an $11M series B round to address this opportunity. New Relic is the current market leader. BlueStripe and VMware with AppSpeed are also targeting this space.

“What do you wish to monitor?”, is often my response when someone states they need to monitor the virtual environment. Monitoring however becomes much more of an issue when you enter the cloud. Some of my friends have businesses that use the cloud, specifically private IaaS clouds, but what should the cloud provider monitor and what should the tenant monitor has been a struggle and a debate when dealing with them.

VMforce = Java + Spring Java Platform + vCloud + SalesForce Data Center

VMware and SalesForce.com have come together to provide a robust, scalable PaaS offering for Java Developers. Existing Force.com developers will now have the ability to use Java to build and extend their applications and all Java developers will have a significant and productive new run time option for their applications. VMware and SalesForce.com have both ratcheted up the pressure on Microsoft in a significant manner.

the Cloud is increasingly being used to provide external security testing services (such as AVS, Application Vulnerability Scanning). The argument of the proponents of such services is that security threats come from the cloud, and thus it makes most sense to embed the AVS in the cloud. However after very detailed examination of the options we have come to the conclusion that the Cloud it isn’t necessarily the right answer for many enterprises, and that the AVS service may best be delivered inside the datacenter.

Does an evaluation for a virtualisation project need to be only an exercise in understanding if X hosts will on Y servers? Will you be able to to virtualize every service you deliver? Are new applications required? What are your existing service-levels and requirements across your application portfolio? In most enterprises today, IT is a cost centre not a profit centre. Business units often want detailed involvement in implementation plans, asset purchases and ownership: it is not unusual that requests for applications come in terms of functionality – not in terms of service levels. With their release of Workspace iQ, Centrix Software appear to be unique in endeavouring to aggregate information that can be used to deliver data that can help provide IT with improved costing information without relying on specific vendors solutions to be in place.
