🔮 Edge to Core to Cloud and the Evolution of Hyperscale Cloud Service Providers

Edge to Core to Cloud is a marketing phrase that has reached the teenager stage. Originally, the phrase was meant to convey the places where data resides by data storage OEMs.

I’ve frequently used the phrase in public speaking and executive briefings since the early 2010s. Back then, while at VCE (2010-2020), my blogging was primarily internal, focusing on private cloud topics related to converged and hyperconverged infrastructure — a hot topic at the time.

During those years, my public posting[1] was geared to private cloud topics associated with converged and hyperconverged infrastructure. It was a thing. 🤓

My first uses of edge to core to cloud on my blog / newsletter back to 2021 when I wrote 100 ‘Fudge Sunday’ posts inspired by song titles and lyrics, which I also compiled into a[2]. Even after a baker’s dozen references[3], there’s still much more to explore on this topic…

Depending on the context, my use of edge to core to cloud refers to the various locations where data solutions can be implemented. In the context of product management, edge to core to cloud addresses the entire spectrum of data needs, from small to large-scale operations.

  • Edge usually refers to edge computing (or distributed computing) which could mean a cloud computing model that is placed at the very edge of a network where data is created, captured, and manipulated.
  • Core usually refers to on-premises data centers which could mean a cloud computing model that would probably be described as a private cloud.
  • Cloud might refer to hyperscale cloud service providers like AWS, Azure, GCP, OCI, etc. that would probably be described as a public cloud but it doesn’t necessarily need to be hyperscale and could easily be a managed service provider (MSP) operating below hyperscale.

Note: To add to this mix of terms, “hybrid cloud” and “multicloud” or “hybrid multicloud” might be a combination of both core and cloud. There is even the notion of a “supercloud”. Or, you could say “soup to nuts” if the context is edge to cloud. 🍲 🥜

In other words, the computing paradigm begins with where — and that drives the what, why, and how. So, edge to core to cloud might start with location but that will lead to other differences that dictate architecture and how various resources are allocated for computational purposes.

There are a few generalities to consider for the computing paradigms. However, the general characteristics of these computing paradigms tend to converge over time, creating overlaps that blur the lines between them and make categorization increasingly challenging…

Computing Paradigm Location Generalities
Edge Distributed IT infrastructure at the source of data generation nearer to the edge of a network
Core Central data centers or colocation of IT infrastructure
Cloud IT Infrastructure as a Service (IaaS) provided by cloud service providers or managed service providers

Of course, in the world of business, cost is another distinction. To simplify further, the general trends of capital expense and operating expense are weighted.

Computing Paradigm Cost Generalities
Edge Costs are typically based on the extent of distribution as incremental upfront CAPEX with expectations of very low unit pricing with ongoing OPEX
Core Costs are typically based on large centralized upfront CAPEX with relatively high unit pricing and ongoing OPEX
Cloud Costs are typically based on a subscription-based utility pricing model that is purely OPEX

📰 News

Coverage of edge to core to cloud has favored OEMs in recent years by unbundling hardware appliances in favor of software-only deployable solutions that can be consumed through Hyperscale cloud service provider (CSP) marketplaces or turnkey OPEX hosted within a REIT along with professional services. From the other end, CSPs have seen mixed results by moving further to the edge and OEM-like appliances and embracing wider ISV/IHV/MSP alliances with unique partner competency specializations.

OEM Examples of moving closer to the cloud or edge

  • Dell Technologies APEX[4] and Edge Services[5]
  • HPE GreenLake[6]
  • Oracle Internet of Things Suite[7]

CSP Examples of moving closer to the core

  • AWS Outposts[8], AWS Local[9], and Wavelength[10]
  • Microsoft Azure Stack Hub[11], ExpressRoute[12], and Azure Stack Edge[13]
  • Oracle Engineered Systems[14] and Enterprise Communications Platform (ECP)[15]

🤖 Technology

As a gentle reminder, Gartner produces a Magic Quadrant for Global Industrial IoT Platforms that is published each year. However, only a small number of hyperscale CSPs are truly participating at the edge in terms of IoT and IIoT.

Note: Google Cloud[16], IBM Cloud[17], and Akamai[18] have exited the edge / IoT platforms market.

For these CSPs, processing power will be a fascinating topic as different players make their moves with future roadmaps. For example, the growing need for photonics solutions and practical liquid cooling maintenance solutions from OEMs will be increasingly important for edge and core as well as cloud.

Computing Paradigm Processing Power
Edge Limited processing power (as compared to core and cloud) optimized for real-time data analysis
Core High processing power for complex workloads and analytics that can scale up (based on CAPEX budget) and scale out within the limits of data center capacity
Cloud Highest scalable processing power for scale up and scale out (based on OPEX budget) for massive datasets and applications within the limits of regions and availability zones

As for cloud, custom ASICs at CSPs will challenge the notion that AMD, Intel, or NVIDIA are the only chips to consider within AWS and Azure. Furthermore, custom ASICs being used by CSPs will open the possibilities for chips to reach edge and core use cases in the future — which might be interesting for the OEMs.

  • AWS Graviton[19] (efficiency and performance differentiator)
  • AWS Nitro[20] (confidential computing and secure enclaves)
  • AWS Trainium[21] (AI/ML training)
  • AWS Inferentia[22] (AI/ML inference)
  • Azure Maia[23] (AI/ML)
  • Azure Cobalt[24] (efficiency and performance differentiator)

Granted, Google Cloud exited the edge but there is still room for core and cloud if you want fries[25] with that perhaps?

  • GCP Titanium[26] (offload)
  • GCP Axion[27] (efficiency and performance differentiator)
  • GCP TPU series[28] (AI/ML)

Of course, there are AMD, Intel, and NVIDIA to consider.

  • AMD: The continued development and successors to AMD’s MI series, Instinct, Alveo, DPU/Pensando, offload, etc. will mean there are competition, enablement, and partnership potentials.
  • Intel: As for Intel, it’s likely to be a similar story with some decisions pending[29] [30] [31] [32].
  • NVIDIA: With NVIDIA, anything seems possible[33] [34].

Storage of data is a function of the budget envelopes of power, weight, cooling, and geometry in the deployment location. Each envelope has a cost implication for both storage performance and capacity[35].

Computing Paradigm Storage Performance and Capacity
Edge Limited capacity with high performance (temporary or caching)
Core Moderate to vast capacity with tiered performance (depending on CAPEX budget for highest performance with tiers for frequently accessed to less frequently accessed to infrequently accessed long-term retention)
Cloud Vast capacity with tiered performance (performance access and frequency of access have the strongest cost function since the economics and architecture are ideally suited for archiving or long-term retention)

Latency is a particular challenge for cloud and core, as they are often farther from the data source. In contrast, edge excels in scenarios requiring real-time decision-making, such as on a factory floor or within a SCADA system, because it’s located closer to where data is generated.

Computing Paradigm Latency Generalities
Edge Ultra-low latency and real-time decision-making limited by distances
Core Moderate latency based on network architecture and distances
Cloud Variable latency depending on network architecture, connectivity, and geographical distance

Locality and proximity selections for edge to core to cloud and REITs are (still) not fully software defined. REITs and MSPs are investing in their network fabrics and Network as a Service (NaaS) outcomes. On the CSP side, AWS Direct Connect, Microsoft Azure ExpressRoute Direct, Oracle Cloud Infrastructure FastConnect, and Google Cloud Platform Dedicated Interconnect seek cloud connectivity for the lowest distance to the core where alternative approaches such as network-to-network interface (NNI) can be a lower cost option for an acceptable but nonetheless lowered level of performance.

🏗️ Use Cases

Speaking of use cases, the world is not shrinking because the edge is known for getting larger and larger due to a paradox[36]. Also, the ability to mix and match use cases across computing paradigms means overlapping and often complimentary (hybrid) solutions are required to solve challenges as a continuum.

Computing Paradigm Samples and Examples
Edge Industrial automation, IoT/IIoT applications, real-time analytics, SCADA, healthcare bedside delivery, content delivery networks, ADAS, etc.
Core Data warehousing solutions, data lake houses, enterprise applications, healthcare centralized workloads, business intelligence solutions, end user data processing, etc.
Cloud Big data analytics, machine learning, artificial intelligence, high-performance computing, healthcare aggregated workloads, etc.

📐 Standards

For CSPs, security related standards are always evolving and improving with an emphasis on scale that moves the industry towards policy as code (PaC). From the policy perspective, groups such as CNCF[37] bring together working groups[38] to apply cloud thinking to the edge that can also be used in the core.

Computing Paradigm Security Considerations
Edge May offer increased physical security and control over data but simultaneously requires additional physical hardening investments that may include fully isolated architectures that have no connectivity to the public internet (fully air-gapped, dark sites, etc.)
Core Offers security dependent upon the on-premises infrastructure as well as staff / trusted third-parties with physical and logical access expertise
Cloud Typically shared responsibility models relies on the CSP security measures and compliance certifications combined with the RACI matrix elements that are jointly owned by the CSP and end customer / trusted third-parties or owned entirely by the end customer with an underlying chain of trust for operational services outside of customer controls

Management

Computing Paradigm Management Description
Edge Requires specialized expertise for managing distributed edge devices
Core Requires IT staff for on-premises infrastructure management
Cloud Managed by cloud service provider, reduces operational overhead

🗣️ Analysis

Google Trends y'all

This market will experience dynamic convergence. The convergence will be driven by the OEM’s business model and the CSP’s connectivity capabilities.

Somewhere in the middle (i.e. REITs and CSP marketplaces) is an example that will provide the benefits of the CSP in terms of OPEX combined with the flexibility to deploy in any location. It’s unclear which player will offer the most effective management and operations control plane for diverse deployments.

Vertical integration may only be feasible if open interoperability standards fail and there’s a persistent lack of global government oversight to ensure fair competition. The good news is when presented with market opportunity, partnerships, and alliances based on open standards have been (arguably) more successful than any one company attempting to own and control a stack from top to bottom — or governments have stepped in to limit M&A up front or break monopolistic single companies apart afterwards.

In my opinion, it is very reasonable to expect the Oracle and IBM model of technology, software, services, and a cloud to become an exit pattern for other OEM companies like Dell Technologies, HPE, Lenovo, Cisco, and other smaller players. The only question is if the pattern is M&A, carve out divestitures, or long term partnerships driving alliance arrangements to be better together with AWS, Azure, GCP, or another CSP that emerges later.

As I would say in my past “Fudge Sunday” series — place your bets.

🗓️ Events

It is worth noting the CSPs are growing their conferences while OEM’s seem to be shrinking their conferences. However, I’ll reserve commentary on that trend for another time as it requires a bit more nuanced quantitative analysis.
