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)

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...

Cloud Management: The Agentless Approach

Automating the deployment and runtime management of large application deployments running on multiple cloud resources across various cloud providers is a challenging problem. Managing remote resources is not a new problem the big difference is that in cloud the resources are added and removed dynamically and at a larger scale. Before cloud people have built management systems using two approaches: Agent Agentless Historically the major trade-off between the agent and the agentless approach has been control vs. rollout time and maintenance costs. You usually get more control with t... (more)
