Enabling successful cloud adoption with an effective operating model: Part one

by Rackspace Technology Staff

Cloud computing has become the new normal for a lot of enterprises, start-ups, and those companies that still run legacy systems. Embarking on digital transformation by leveraging the cloud is one of their top priorities.

Why the majority of the cloud adoptions stall

Most journeys of cloud adoption fail in one way or another. Often, companies begin with a strong passion, approve a long-term budget, and achieve limited success in piloting something new in the cloud. After this initial pilot, the transformation then starts to slow down or stall. The cloud team fails to attract more incoming workloads and the stakeholders' passion declines. The transformation then loses its momentum and might come to a complete halt. 
The story sounds all too familiar, and quite often, the failure has nothing to do with technology. In fact, most enterprises' challenges in cloud adoption are due to non-technical issues. The journey to a modern, cloud-enabled enterprise is mostly about transforming the people and how they operate within a new environment. 

What has Cloud changed? 

  • Cloud computing offers unlimited on-demand capacity. Data centers constrain new development because of their limited capacity.
  • Data centers offer only bare metal and infrastructure services, whereas clouds can offer various applications (SaaS) and platform solutions (PaaS) to address business needs.
  • Cloud computing offers flexibility to scale and pay-as-you-go without upfront capital investment. In contrast, most data centers require a long lead time to expand because of the budgeting and procurement process.
  • Corporate IT centralizes data center resource management and operations, but with the public cloud, all stakeholders have a level playing field for technology and can consume cloud services directly.

The preceding considerations show that cloud computing can radically change how you achieve digital transformation with improved speed and flexibility, and reduced costs. However, companies do not reap such benefits by just adopting new technologies. They must also deploy an appropriate operating model to unlock the immense value of clouds regarding efficiency and flexibility.

The operating model is the key to aligning the business and IT

To understand why the operating model matters to gain cloud benefits, we can start by articulating the intrinsic needs of business and IT within companies and how appropriate operating models can align business and IT to create common goals. 
The success of business primarily focuses on business differentiation and the pace of response to market change. Most business stakeholders emphasize the speed to market by having the autonomy, efficiency, and flexibility to experiment with new ideas and products. On the other hand, IT focuses on the cost and stability for delivering and consuming IT services across the entire company and ensures they can satisfy all compliance requirements with mitigated risks. This contrast is likely to create two opposing forces, which the following diagram illustrates:

Figure 1: The intrinsic frictions between Business and IT

The objectives and desired outcomes that business and IT want to achieve are intrinsically different. One of the few areas that can bring business and IT together is innovation, broadly referred to as digital transformation. The business pursues more creative ways to respond to customer needs through business innovation, whereas IT pursues the safe deployment of advanced technologies to support new business requirements. The Public Cloud is the right-fit platform to meet these objectives from both sides. However, suppose both sides continue to operate on their own turf with the same operational framework, guardrail, process, and mindset. In that case, putting more workloads on cloud only provides a short-lived passion rather than a sustainable practice. This explains why many cloud adoption journeys failed.

Activity-based teams versus outcome-based teams

The operating model is a framework that determines how you create, deliver, or consume IT services or products. In a nutshell, it specifies the protocol, process, guardrail, resources, roles, and responsibilities to enable IT service providers and IT service consumers to interact effectively to support business needs. Figure 2 profiles typical functions between service providers and service consumers out of an abstract operating model framework.

We can always view the core functions of the entire ITSM ecosystem as technologies covering application and platform, intersecting with responsibilities covering engineering (build) and operations (support). If we position the end-users at the top and the cloud resources and associated infrastructure at the bottom, stakeholders provision services at a lower layer and receive them at an upper layer. In a typical flow, the platform team operates on the cloud resources to deliver platform and infrastructure services to the application team. The application team consumes those services to develop and deliver the required application services, which unlock the business capabilities of the end-users who run the applications.

The elasticity, automation, and on-demand nature of resource and service deployment on Cloud platforms have enabled companies to operate their IT environment effectively with DevOps. Rather than having different teams assuming responsibilities associated with each of the four quadrants of the operating model, companies can set up special-purpose teams comprising skills to operate technologies and resources across multiple quadrants to achieve target outcomes. This structure removes the traditional organization boundary, delimiting each team from a singular responsibility or activity area and accelerating the operations and changes associated with routine work and business innovation.

To illustrate the preceding concept and understand why the operating model should vary during cloud adoption, you can think of a hypothetical scenario in which a company develops and maintains three different types of applications:

  • Traditional: These legacy applications were developed and in use for a long time. Most of them undertake limited changes. They primarily deliver routine business capabilities and back-office functions to achieve business sustainability.
  •  Optimized: These applications provide capabilities enabling business growth. Developers most likely built them by using the Agile process and advanced technologies, such as those associated with microservices, serverless, and centralized API platforms.  These applications undertake more frequent changes and are highly responsive to business demands. 
  • Start-up: These new-built applications try to capture new opportunities, experiment with new ideas, or deliver a proof of concept. They are under massive development work, but their success hinges on small but frequent incremental changes implemented over a prescribed timeline. The company aims to reap quick benefits and determine if the investment should continue based on initial results or outcomes.

The following table compares the three application scenarios across several perspectives:

It is not uncommon to witness all three application scenarios within a mid-to-large-size company, and in such cases, what would be the appropriate cloud operating model? The short answer is: there is no one-size-fits-all operating model that works well for all applications. 

Before embarking on the cloud adoption journey, many companies operate their ITSM ecosystem with a dedicated business unit for each of the four quadrants of their operating model (see Figure 2). Another common scenario is having a Managed Service Provider (MSP) in charge of all platform services, collectively assuming all responsibilities associated with platform engineering and platform operations (such as the lower half of the operating model).  

When the company transfers its workloads to the Cloud, the suitable operating model depends on how well it can leverage DevOps to effectively build, maintain, and operate the transferring application.

Due to their monolithic design and tightly coupled architecture, many activity-based teams usually maintain traditional legacy applications. Each team focuses on only one well-defined competency area, such as database, network, or storage. Changes and maintenance normally require one team to pass outputs to another team as input for performing their respective activities. Inevitably, this results in handoffs. These applications are likely candidates for lift-and-shift (rehosting) to cloud because changing their architecture or solution components often results in unacceptable risks and investment. 

The start-up applications based on the Agile approach, on the contrary, do not have the constraints of the monolithic architecture. They have several loosely-coupled, independent solution components. Each has a specific outcome contributing to the overall system or initiative. For example, it could be secure access to an API platform for exchanging data between applications or a data analysis platform for internet traffic to detect cyber threats.
Other applications can reuse these solution components if needed. A full-stack outcome-based engineering team is responsible for building, maintaining, and operating each of these independent components. The team picks up workloads alongside an automated CI/CD pipeline and is self-sufficient to achieve its target outcomes without handoffs. 

Figure 3 best illustrates the difference between the two team protocols:

It is important to note that each activity-based team does not by itself produce the final results. Instead, it needs to work with other activity-based teams to produce the final outcome with meaningful value. However, within a full-stack outcome-based team, all team members work together to produce target deliverables that release well-defined business value. Once we understand these subtle differences, the adoption of the right operating model becomes more intuitive.
