In a discussion about the cloud with business executives, one brave CEO asked, “So what does “cloud” even mean? I hear things like cloud, the cloud, cloud services, and cloud computing. Do they all mean the same thing?”
Crystal Peterson from STG offered a simple way for business executives to think about all things cloud. As the CEO of a technology consulting firm, she acknowledged that a simple explanation may sound too simplistic to her peers and technology professionals.
She makes it easy enough for business leaders to understand while being true to the complex principles. Even so, this document is for executives who are serious about getting a grasp of all things cloud. It unfolds key concepts and then suggests guiding principles and questions for introspection and further discussion by interested leaders.
The terms cloud, cloud computing, and DevOps form a continuum of concepts and practices in IT and software development, each building upon and intersecting with the others. Here’s a breakdown:
Cloud: Strategy and Vision
Definition: At its core, “cloud” refers to a computing paradigm that leverages remote servers accessed over the internet or private connection to store, manage, and process data instead of using local servers or personal devices. It’s not just technology but a business strategy and approach to IT resource management.
A cloud strategy encompasses a company’s goals and methods for adopting and leveraging cloud technologies. This includes deciding on public cloud, private cloud, or hybrid cloud solutions, selecting cloud service providers, and aligning cloud adoption with organizational objectives.
The cloud is also about enabling agility, scalability, and innovation by offloading hardware infrastructure and shifting to as-a-service models.
Examples of cloud strategy might include using the cloud to reduce capital expenses, improve disaster recovery capabilities, improve security, or facilitate global collaboration.
Business leaders may find the following guiding principles that will be useful as they engage in meaningful conversations about technology and cloud strategy.
Understand the business objectives driving the adoption of cloud.
Recognize the various cloud service models (IaaS, PaaS, SaaS are defined below) and deployment types (public cloud, private cloud, hybrid, multi-cloud).
Highlight the shift from CapEx (capital expenses) to OpEx (operational expenses).
Cloud Computing: Tools and Implementation
Definition: Cloud computing is the practical implementation of cloud strategy. It involves the delivery of computing services—such as servers, storage, databases, networking, software, and analytics—over the Internet.
Cloud Computing focuses on how resources are used, provisioned, and managed within the cloud. With the help of capable technology specialists like those employed by STG, cloud computing offers flexibility, resiliency, on-demand availability, and cost-effectiveness through pay-as-you-go pricing.
Without proper guidance, however, companies migrating to the cloud can suffer from spiraling costs, sluggish application performance, and increased security risks.
Some common terms associated with cloud computing are IaaS, Paas, and Saas.
IaaS stands for Infrastructure as a Service. It is a cloud computing model that provides virtualized computing resources over the internet. With IaaS, businesses can access and manage IT infrastructure components such as servers, storage, networking, and operating systems on a pay-as-you-go basis without the obligation to own or maintain physical hardware.
The key features of IaaS include avoiding upfront capital expense payment, scalability of resources based on demand, only paying for the resources you use, and right-sizing the infrastructure according to specific needs. You can also usually reduce or remove internal IT personnel handling on-premise infrastructure.
These IaaS features ease the maintenance burden, accelerate project timelines, and enhance security and disaster recovery. IaaS is ideal for businesses needing high flexibility and control over their computing resources without the burden of managing physical infrastructure.
PaaS stands for Platform as a Service. A cloud computing model that provides a platform and environment to build, test, deploy, and manage applications without the complexity of managing the underlying infrastructure.
With PaaS, developers can focus on coding and application development while the cloud provider handles the underlying hardware, operating systems, middleware, and development tools.
Key features of Paas include development frameworks for faster application development. It includes tools for coding, testing, version control, and deployment. Paas enhances scalability and shifts the burden for servers, storage, networking, and other backend components to the cloud provider.
An important takeaway for top business leaders is that engaging a technology partner like STG that is independent of vendors is crucial to getting the best solution for their company. A technology consultant with bias for or against specific potential solutions will result in a compromised strategy. Make sure your technology partner is independent.
The benefits associated with Paas include developers focused on innovation and writing code rather than managing infrastructure. When appropriately planned and engineered, companies can expect cost efficiency, flexibility, and streamlined deployment capability. PaaS is ideal for organizations looking to accelerate application development and streamline the deployment process while minimizing operational complexity.
SaaS stands for Software as a Service. A cloud computing model where software applications are delivered over the internet. Instead of purchasing and installing software on individual devices, users access it via a web browser, usually on a subscription basis.
Key features of SaaS models include web-based access to software applications that the provider manages, enhances, and supports. It is usually characterized by pay-as-you-go pricing with easy scalability to accommodate variations in workload.
Saas applications are widely available, and examples include productivity tools, e-commerce solutions, and enterprise resource planning (ERP).
The benefits of automatic updates and ease of use make the SaaS model popular. SaaS is a convenient, cost-effective solution for businesses and individuals looking for ready-to-use, accessible, and scalable software without the burden of managing the underlying software code and infrastructure.
Business leaders may find the following guiding principles to be useful as they engage in meaningful conversations about technology and cloud strategy.
Differentiate between the layers of cloud services (IaaS, PaaS, SaaS).
Emphasize scalability and elasticity as core benefits.
Acknowledge security, data sovereignty, and compliance concerns.
DevOps: Practices and Culture
Definition: DevOps is a set of practices and cultural philosophies that improve collaboration between development and IT operations teams. It often uses automation and continuous delivery to improve software delivery speed and quality.
DevOps is not tied to cloud but aligns naturally with cloud computing because of its focus on agility, scalability, and automation. It bridges the gap between code development and operations, enabling faster deployment, better quality, and more reliable updates. Core practices include continuous integration/continuous deployment (CI/CD), infrastructure as code (IaC), and containerization.
Business leaders may find the following guiding principles to be useful as they engage in meaningful conversations about technology and cloud strategy.
Highlight DevOps’ role in breaking down silos between teams.
Stress the importance of CI/CD and IaC in enabling faster and more reliable software delivery.
(Continuous Integration / Continuous Deployment and Infrastructure as Code)
Explain how DevOps practices improve feedback loops, reduce downtime, and enhance collaboration.
Connecting the Continuum
Cloud provides the strategic foundation, enabling the scalability and flexibility required to adopt modern IT practices.
Cloud Computing is the technical framework and implementation, giving businesses the tools and infrastructure to operationalize their cloud strategies.
DevOps adds an operational layer and the right culture to help the teams focus and collaborate to deliver value quickly and efficiently.
Fundamental Guiding Questions Business Leaders Can Use for Discussing “Cloud”:
- What problem is the organization solving by moving to the cloud (e.g., scalability, cost reduction, increased security, reliability, global accessibility)?
- What cloud service and deployment models are being used, and why were they chosen?
- How is the organization leveraging cloud computing to innovate and improve efficiency?
- Are DevOps practices being integrated with cloud adoption to maximize the value of automation and agility?
By understanding the nuances of cloud, cloud computing, and DevOps, you can meaningfully discuss value, implications, challenges, and options, tailoring the message to technical and business audiences alike.
