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)

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 ...

Deploying and Managing Custom Apps in the Cloud

At Kaavo we recognized that there is a need to provide a horizontal framework that anyone can use to quickly build a vertical solution for running and managing their complex custom applications in the cloud. To enable single click deployment and runtime management of any custom application in the cloud Kaavo’s IMOD uses System Definition file for automating complex workflows and dependencies for deployment and runtime management.  Understanding the structure of System Definition file is important to fully benefit from Kaavo’s application centric management approach. System Defin... (more)

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)

Cloud Management – Various Solutions and Standards

The growing use of Infrastructure as a Service to run custom applications, SaaS, and PaaS offerings is increasing the demand of management solutions to leverage the automation offered by IaaS.  One of the biggest advantages of IaaS is the ability to automate tasks which were not possible before.  E.g. a crashed server can be restored with an API call by launching a new instance.  Effective use of the IaaS APIs can dramatically reduce the time and resources it takes to deploy and provide production support for services and applications. Various solutions and standards are availab... (more)
