Introduction

In this article, we will delve into the fascinating world of cloud-edge technology and explore the intricate relationship between edge computing and cloud computing. With the rapid development and adoption of these technologies in 2022, it is essential for companies to understand how they can effectively support their edge to cloud technology. To shed light on this topic, we have the privilege of speaking with Sachin Kade, the Network and Edge Group CTO at Intel. Sachin will share his expertise and insights into the state of cloud edge technology, the growing interdependence between edge and cloud, and the future of this transformative field.

The Relationship between Edge Computing and Cloud Computing

Cloud computing has experienced immense investment and growth in the past decade, making it the default choice for enterprise IT deployments. Simultaneously, edge computing has also been rapidly evolving, entering a phase of exponential growth. The question arises: to what extent do these two technologies enable each other?

Edge computing is powered by what we refer to as "edge native workloads." These are applications or workloads that are designed to live and operate at the edge rather than in the cloud. There are several reasons for this preference, such as physical location requirements, data sovereignty regulations, or economic factors. Edge native applications necessitate the availability of edge computing platforms to support their unique needs.

However, it is crucial to note that edge deployments still leverage cloud computing capabilities. While the main workload may reside at the edge, applications often rely on the cloud for long-term storage and coordination across multiple edge locations. In this sense, the cloud serves as an orchestration system for the various edge computing systems deployed throughout a distributed network.

Thus, edge and cloud are closely intertwined, making it rare to find an edge deployment without some level of cloud integration.

The State of Cloud Edge Technology

The edge computing landscape is entering a transformative phase of exponential growth, commonly referred to as the "hockey stick" growth phase. This growth is primarily driven by the emergence of edge native applications, which have unique requirements and preferences for operating at the edge.

Various factors contribute to the rise of edge native applications. For instance, the shift towards remote work necessitates distributed networking and security software. Additionally, labor shortages and inflation have prompted the need to digitize and automate physical infrastructure. Furthermore, privacy concerns and governmental regulations require data to remain at the edge.

These factors contribute to the proliferation of edge native applications and the corresponding edge computing platforms powering them. While the cloud predominantly serves as an orchestration and management system for these distributed deployments, it is essential to acknowledge the growing importance of the edge in performing crucial data processing tasks closer to the source.

Edge Native Workloads

Edge native workloads are at the core of the edge computing revolution. These are new applications that were "born at the edge" and are designed to operate specifically within edge environments. Unlike cloud native applications that are built to run in the cloud, edge native workloads thrive in a distributed edge ecosystem.

One example of an edge native application is the emergence of cashier-less checkout systems in modern retail stores. These systems utilize sensors and cameras for visual checkout, which requires real-time processing and cannot depend solely on cloud connectivity. Edge native workloads are specifically tailored to operate at the edge, taking advantage of the proximity to data sources, lower latency, and enhanced reliability.

Edge native workloads differ from cloud native workloads in their resource requirements. Since edge deployments often face resource constraints, edge native applications are designed to be more lightweight and focused on specific tasks. While cloud native applications benefit from large-Scale storage and AI training engines, edge native applications primarily focus on running inferencing tasks and rely on the cloud for training and coordination.

The Role of the Cloud in Edge Computing

Although edge computing enables local data processing and quick responses, the cloud remains a crucial component of edge deployments. Cloud technologies are leveraged in multiple ways to enhance edge computing capabilities.

Firstly, the cloud offers a range of tools and frameworks, such as Kubernetes and modern DevOps toolchains, that developers are familiar with and can utilize at the edge. These technologies enable consistency and streamline management processes across both the cloud and edge environments.

Furthermore, the cloud provides burst capacity, which is vital in scenarios where the edge may not be fully provisioned or requires extra computing power temporarily. The cloud's ability to provision resources on-demand complements the limited resources of edge deployments.

Moreover, the cloud serves as a centralized management engine for highly distributed edge deployments. It facilitates the coordination and orchestration of various edge computing systems deployed across multiple locations. This centralization reduces operational complexity and enables efficient management of the entire edge ecosystem.

In summary, the cloud and edge work HAND in hand, with the cloud serving as an essential supporting element in edge deployments.

Advice for Building an Edge Deployment

Building an edge deployment involves navigating several key factors that distinguish it from traditional cloud deployments. Here are some essential considerations and advice for companies venturing into the edge computing landscape:

Embrace the distributed nature of edge computing: Edge deployments are inherently distributed, with compute resources spread across multiple locations. Companies must be prepared to manage and address the inherent challenges that arise from operating in a distributed environment. Factors like network connectivity, power variability, and resource constraints need to be carefully accounted for.
Select the right compute platform and software stack: Edge deployments require a compute platform and software stack that can handle the unique variations and constraints of edge environments. Ensure that the chosen platform is specifically designed for edge deployments and can handle distributed workloads efficiently. It is essential to prioritize scalability, flexibility, and reliability when selecting the hardware and software components for the edge.
Tailor applications for the edge: Edge deployments have distinct application requirements compared to cloud-native environments. Edge deployments typically run inference workloads rather than large-scale storage systems or AI training engines. Optimize the software stack to be more lightweight and focused on the specific demands of edge computing. It is crucial to strike the right balance between operational efficiency and resource utilization at the edge.
Pay attention to orchestration and management: The distributed nature of edge deployments necessitates robust orchestration and management capabilities. Deploying software and managing systems across multiple edge locations can quickly become operationally overwhelming. Establish an effective orchestration strategy and leverage tools that simplify management, automation, and coordination across the distributed edge ecosystem.
Architect data management strategically: Data at the edge is a critical component of edge deployments. While edge devices may not have the capacity to process large amounts of data, the data generated by edge devices needs to be collected, consolidated, and processed in an edge computing platform. Design a data management strategy that strikes a balance between processing data at the edge and leveraging the cloud for long-term storage and data coordination.

By considering these factors and embracing the unique demands and opportunities of edge computing, companies can build successful and efficient edge deployments that meet their specific business needs.
