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 technologies such as encrypted storage, Virtual Local Area Networks, and network middle boxes (e.g. firewalls, packet filters). For example, encrypting data before placing it in a Cloud may be even more secure than unencrypted data in a local data center; this approach was successfully used ... (more)

The Benefits and Challenges of Virtualization, Private and Public Clouds

After my earlier blog discussing the evolution of IT, I had several discussions on the benefits and challenges of virtualization, private, and public clouds.  Following bar chart is an attempt to capture the benefits and challenges of various phases of IT evolution from the days of having dedicated physical servers for each application to the use of public cloud. The chart is self explanatory, some key points to note are: Going from virtualization to private cloud is basically a step to provide self service capabilities to the application owners.  It increases flexibility and als...

Oracle support for Amazon EC2 and its implications on the industry

This past week, Oracle announced that it will be fully supporting and certifying a range of its software products including E-Business Suite, PeopleSoft Enterprise, Siebel CRM, Fusion Middleware, etc. on Amazon EC2.  This is a huge win for Amazon and a very big win and validation for the Infrastructure as a Service industry.  What is interesting about this announcement, is that for supporting EC2, Amazon is enabling Oracle to run their applications in Oracle VM on EC2 instead of the standard XEN VM used in Amazon EC2.   This is an interesting move on the part of Oracle and will ...

Is Amazon following Kaavo in Cloud Management?

Today I received an email from Amazon announcing their AWS CloudFormation Service.  Basically to automate the deployment of complex applications or workloads Amazon is allowing users to capture all the deployment information in one template. They call the template “Stack”.  Taking a top down view of the deployment and capturing all the information for deploying and managing an application or workload in the cloud in one place is at the heart of Kaavo’s Application centric approach.  We released GA version of Kaavo IMOD in early 2009 to enable automatic deployment and runtime man...

Using Cloud for Disaster Recovery

Use of cloud for DR solutions is becoming more common, even the organizations which are not using cloud for mission critical production applications are moving towards using cloud for application DR. Business Case for Using Cloud for the DR Faster Recovery Time Objective (RTO): Typically DR requires lengthy manual processes to fully restore the business applications at the DR site.  Having backup data and servers at the DR site is easy, however, restoring the entire application or service takes time.  E.g. full application restoration requires starting services in specified order...
