As described in the last week’s post NIST defines three different cloud computing service models – IaaS, PaaS and SaaS. IaaS and SaaS are really easy to grasp but I see people struggling to understand the PaaS model. As a long-time application developer though I find the PaaS model the most compelling one for new applications. Here is why.
I will look at two examples: one enterprise and one from the consumer world.
Let’s start with the enterprise scenario. If you examine any enterprise application portfolio you will find out that almost every development team has implemented it’s own code for handling common functionality like authentication, authorization, database access etc. There are also numerous cases when the same team developed the same functionality over and over in each new project. Even the componentization model doesn’t help in this situation because either developers are often not aware of the existence of the components or there are too many options they can choose from and they cannot find the right fit for their scenario. The Service Oriented Architecture (SOA) was the holly grail for this problem but many enterprises are still far from achieving this goal.

Technology, Innovation and Futile Feats
During a recent conversation with a CIO of a multi-billion dollar enterprise and his top executives, it became apparent that amid all the new technology advancements like cloud computing and Big Data, organizations are struggling to seek the concrete advantages in applying these technologies to their own real-world scenarios. Even more worrisome is the situation that occurs when an organization cannot leverage any of the already-proven solution approaches or services to address a specific problem or a concern and the situation remains unresolved over time.
These issues could very well be rooted in the way an organization goes about solving problems. Or they can reflect the inability of their service provider and technology vendor to identify the need for change and the implementation of the right solution.
Cloud Compliance in IaaS Is Mainly Your Responsibility
Cloud compliance is always a hot topic, but recent updates to the HIPAA and PCI regulations, have further enhanced the need to clarify some important points around cloud compliance and regulatory compliance. In this blog post, I would like to address some issues as highlighted in the valuable PCI DSS Cloud Computing Guidelines (available here), around compliance and Infrastructure as a Service cloud computing. (While the trigger is the PCI guideline, the discussion applies to HIPAA as well).
First and foremost, the level of control and your ability as a cloud customer to implement security in your cloud environment is dictated by your cloud type. For example a customer using Software as a Service (SaaS) will have the least amount of control and the SaaS provider will have the greatest level of responsibility for data security, while in Infrastructure as a Service (IaaS), the customer has much more control on data security implemented in his cloud account while the IaaS provider will emphasize “shared responsibility”. And to translate it to compliance: A customer in a SaaS environment must rely heavily on the provider’s compliance (which is either there or not), while in a IaaS environment the customer must take active responsibility for compliance together with tools provided by the IaaS cloud provider.

Opposition to Dell Buy-Out Mounts
Michael Dell may be facing a stockholders’ revolt.
T. Rowe Price, the mutual fund biggie that held 4.4% of Dell at the end of the third quarter, isn’t prepared to support the company’s leveraged buy-out at the price the Dell board agreed to last week.
T. Rowe Price chairman and chief investment officer Brian Rogers released a statement saying, “We believe the proposed buyout does not reflect the value of Dell and we do not intend to support the offer as put forward.”
His position mirrors that of Southeastern Asset Management, which is understood to hold 8.4% of Dell and faces a loss of nearly $400 million if the deal goes down at the $13.65 or $24.4 billion agreed to. It claims Dell is worth $24 a share, a price it hasn’t fetched in a long time.
