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.

The notion of improving operational efficiency is conspicuously absent from the healthcare debate - neither Obamacare nor the newly proposed GOP plan discusses the impact that a step-function improvement in efficiency could have on access to healthcare (through more capacity), quality of healthcare services (through reduced wait times for patients) or cost (through better utilization of scarce, expensive assets).

Our work, both with clients and with tools, has lead us to wonder how it is that organizations are handling compliance issues in the cloud. The big cloud vendors offer compliance for their infrastructure, but the shared responsibility model requires that you take certain steps to meet compliance requirements. Which lead us to start poking around a little more. We wanted to get a picture of what was available, and how it was being used. There is a lot of fluidity in this space, as in all things c...
Gone are the days when application development was the daunting task of the highly skilled developers backed with strong IT skills, low code application development has democratized app development and empowered a new generation of citizen developers. There was a time when app development was in the domain of people with complex coding and technical skills. We called these people by various names like programmers, coders, techies, and they usually worked in a world oblivious of the everyday pri...
The goal of Microservices is to improve software delivery speed and increase system safety as scale increases. Microservices being modular these are faster to change and enables an evolutionary architecture where systems can change, as the business needs change. Microservices can scale elastically and by being service oriented can enable APIs natively. Microservices also reduce implementation and release cycle time and enables continuous delivery. This paper provides a logical overview of the Mi...
The “Digital Era” is forcing us to engage with new methods to build, operate and maintain applications. This transformation also implies an evolution to more and more intelligent applications to better engage with the customers, while creating significant market differentiators. In both cases, the cloud has become a key enabler to embrace this digital revolution. So, moving to the cloud is no longer the question; the new questions are HOW and WHEN. To make this equation even more complex, most ...
Some journey to cloud on a mission, others, a deadline. Change management is useful when migrating to public, private or hybrid cloud environments in either case. For most, stakeholder engagement peaks during the planning and post migration phases of a project. Legacy engagements are fairly direct: projects follow a linear progression of activities (the “waterfall” approach) – change managers and application coders work from the same functional and technical requirements. Enablement and develo...

Okay, he isn't really an admiral - nor does anyone call him that - but he used the title admiral to describe what container orchestrators do, relating it to an admiral directing a fleet of container ships. You could also say that they are like the conductor of an orchestra, directing...
The past few years have brought a sea change in the way applications are architected, developed, and consumed—increasing both the complexity of testing and the business impact of software failures. How can software testing professionals keep pace with modern application delivery, given the trends that impact both architectures (cloud, microservices, and APIs) and processes (DevOps, agile, and continuous delivery)? This is where continuous testing comes in. D
Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is foundational - something customers routinely cite as a top pain point. In his session at @DevOpsSummit at 21st Cloud Expo, Bill Borsari, Head of Systems Engineering at Datera, explored how organizations can reap the bene...
The dynamic nature of the cloud means that change is a constant when it comes to modern cloud-based infrastructure. Delivering modern applications to end users, therefore, is a constantly shifting challenge. Delivery automation helps IT Ops teams ensure that apps are providing an optimal end user experience over hybrid-cloud and multi-cloud environments, no matter what the current state of the infrastructure is. To employ a delivery automation strategy that reflects your business rules, making r...

You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.
For DevOps teams, the concepts behind service-oriented architecture (SOA) are nothing new. A style of software design initially made popular in the 1990s, SOA was an alternative to a monolithic application; essentially a collection of coarse-grained components that communicated with each other. Communication would involve either simple data passing or two or more services coordinating some activity. SOA served as a valid approach to solving many architectural problems faced by businesses, as app...
Many IT organizations have come to learn that leveraging cloud infrastructure is not just unavoidable, it’s one of the most effective paths for IT organizations to become more responsive to business needs. Yet with the cloud comes new challenges, including minimizing downtime, decreasing the cost of operations, and preventing employee burnout to name a few. As companies migrate their processes and procedures to their new reality of a cloud-based infrastructure, an incident management solution...
Cloud Governance means many things to many people. Heck, just the word cloud means different things depending on who you are talking to. While definitions can vary, controlling access to cloud resources is invariably a central piece of any governance program. Enterprise cloud computing has transformed IT. Cloud computing decreases time-to-market, improves agility by allowing businesses to adapt quickly to changing market demands, and, ultimately, drives down costs.
Recent survey done across top 500 fortune companies shows almost 70% of the CIO have either heard about IAC from their infrastructure head or they are on their way to implement IAC. Yet if you look under the hood while some level of automation has been done, most of the infrastructure is still managed in much tradition/legacy way. So, what is Infrastructure as Code? how do you determine if your IT infrastructure is truly automated?
Every few years, a disruptive force comes along that prompts us to reframe our understanding of what something means, or how it works. For years, the notion of what a computer is and how you make one went pretty much unchallenged. Then virtualization came along, followed by cloud computing, and most recently containers. Suddenly the old rules no longer seemed to apply, or at least they didn’t always apply. These disruptors made us reconsider our IT worldview.
