In IaaS and PaaS Convergence, It’s PaaS That Should Lead

Operations staffs are having a difficult time trying to deliver a functioning IaaS to end users with a self-service interface

Recent commentaries by cloud industry luminaries Reuven Cohen & Krishnan Subramanian address key issues related to relative importance and potential longevity of an independent Platform-as-a-Service (PaaS). In his commentary, Reuven poses, "Do consumers really care about the difference between IaaS and PaaS?" The answer to this question is most likely, no, but that doesn't eliminate the need for distinction, it merely is a matter of how best to deliver the value of cloud computing to users.

In his commentary, Krishnan does an excellent job of exploring one way to classify PaaS as either service or container orchestration. However, in some ways, the distinction introduces more confusion. For example, his use of Docker illustrates how convergence of IaaS and PaaS actually makes sense for the industry and, thus, diminishes his key point that there's value in the cloud application layer existing as a distinct layer within the cloud stack.

Ultimately, I don't believe either piece truly makes the case for the importance of independence between IaaS and PaaS, which has to do with the ability to optimize for economics of the cloud. Consider a converged IaaS/PaaS environment. IaaS should be optimized for the management and delivery of virtual application infrastructure, e.g. networking, storage and compute. In contrast, PaaS requires optimization for scalability and availability of applications. Moreover, each application requires optimization in different areas, for example, some require high number of storage I/O per second while others, such as Hadoop, rely on the ability to "spin up" and reclaim thousands of virtual servers.

Operations staffs are having a difficult enough time just trying to deliver a functioning IaaS to their end users with a self-service interface. Expecting that IaaS to also support every type of application that application development might ever think of is unreasonable and would drive deeper in operations-related engineering, which is one of the drivers for the high cost of IT. PaaS provides the right level of distribution of responsibility within the enterprise. A well-designed and operated PaaS should provide the appropriate services on which a PaaS could be layered. In turn, the PaaS could then extend the features of IaaS to ensure appropriate support for storage and network performance to operate the application as part of the deployment.

Indeed, if convergence is to occur in the industry, it is PaaS that should expose IaaS functionality and not the other way around. Assuming advancement of software-defined data center (SDDC) architecture, the PaaS should be able to program and configure the necessary infrastructure required for the deployment and management of an application over time. Hence, the application package will become the primary descriptor for the required infrastructure required to operate the application and the SDDC will provision as requested or deny the request for resources. Thus, rendering invalid the need for a self-service portal for provisioning virtual servers and, instead, relying on the cloud application architecture to consume resources as needed.

High-performing enterprise Software Quality Assurance (SQA) teams validate systems that are ready for use - getting most actively involved as components integrate and form complete systems. These teams catch and report on defects, making sure the customer gets the best software possible. SQA teams have leveraged automation and virtualization to execute more thorough testing in less time - bringing Dev and Ops together, ensuring production readiness. Does the emergence of DevOps mean the end of Enterprise SQA? Does the SQA function become redundant? In her session at DevOps Summit, Anne Hungat...
Docker offers a new, lightweight approach to application portability. Applications are shipped using a common container format and managed with a high-level API. Their processes run within isolated namespaces that abstract the operating environment independently of the distribution, versions, network setup, and other details of this environment. This "containerization" has often been nicknamed "the new virtualization." But containers are more than lightweight virtual machines. Beyond their smaller footprint, shorter boot times, and higher consolidation factors, they also bring a lot of new fea...

The term culture has had a polarizing effect among DevOps supporters. Some propose that culture change is critical for success with DevOps, but are remiss to define culture. Some talk about a DevOps culture but then reference activities that could lead to culture change and there are those that talk about culture change as a set of behaviors that need to be adopted by those in IT. There is no question that businesses successful in adopting a DevOps mindset have seen departmental culture change, the question remains, is culture the leading edge of this change? I posit that in large enterprises,...
