Top Stories by Jamal Mazhar

Recently I read an article by Greg Ness.  A quote from the article, "The virtualization players will be forced to build or acquire application layer and connectivity intelligence as a means of survival."  I couldn’t agree more as the dynamic nature of infrastructure resources (virtual servers, virtual networks, etc.) will test the limits of current tools and processes. In the past when servers were within the enterprise boundaries there were fewer physical servers and it was easy to maintain a mapping of what applications are running on what servers (static servers) and their interdependencies.  Now with virtualization unless you are running the actual datacenter, from the application owner perspective there is no concept of physical servers.  And because of the virtualization there is no need to run multiple applications on the same server to increase server...

How Secure Is Data in the Cloud?

University of Berkley has published an excellent paper on cloud computing, the argument regarding data security in the cloud is that encrypted data in the cloud can be more secure than unencrypted data in the internal datacenter. Almost nobody uses encryption in internal datacenters as they are percieved as secure.  Here is an excerpt from the study: “We believe that there are no fundamental obstacles to making a cloud-computing environment as secure as the vast majority of in-house IT environments, and that many of the obstacles can be overcome immediately with well understood ...

Building a Private Cloud Within a Public Cloud

One of our customers wanted to establish a site to site connectivity between their datacenter and  public cloud (Amazon EC2) and then have a private network within Amazon EC2 with their own custom IP addresses for their servers in the cloud.  Basically the idea here is to augment the internal datacenter resources with the resources in the public cloud securely so that the servers in the cloud appear as if they are part of their own private corporate network.  The idea here is to isolate the servers used by the customer in the cloud from the rest of the servers in the cloud using ...

More on Benefits and Challenges of Cloud Computing

Here is the revised version of the bar-chart I posted in the previous blog. It shows the evolution of IT to explain the benefits and challenges of cloud computing, and showing why and how we got to ... (more)

Cloud Ecosystem and How the Players fit in the End-to-End Solution for Enterprise Customers

As we are in the early stages of the transformation offered by cloud computing, there is lot of confusion around how various solutions and offerings fit in the overall picture for enterprise customers and the benefits of various offerings.  Whether you have to deliver SaaS, PaaS, or Custom Apps there are three building blocks you need to deliver them, datacenter with virtualization, IaaS layer on top of virtualization, and application/workload management for efficient deployment and management.  It can be argued that you don’t need virtualization or IaaS to deliver the Sa...
