Edge Computing vs. Computing at The Edge.  Why It Really Matters!

EDGE COMPUTING & COMPUTING AT THE EDGE – IDENTICAL WORDS, IN DIFFERENT ORDER, DELIVERING STARKLY DIFFERENT OUTCOMES

Computing at the edge replicates your data centers.

Companies adopt this strategy in order to process closer to the customer and reduce network latency.  While these ‘edge’ data centers may be physically smaller than centralized data centers, they rely on the same complex and expensive software infrastructure as large data centers.

If one replicates data centers, costs replicate as well.  These data centers at the network edge use VMware, Oracle, security products, and all of the other software infrastructure products associated with data centers – including all of their associated costs.

If one runs the same infrastructure as the main data center or cloud, everything else follows – apps are cumbersome, expensive, hard to build and increasingly difficult to maintain.

The firms using this strategy of computing at the edge by replicating data centers at the edge of the network will not achieve sustainable differentiation from their competitors.

Computing at the edge is NOT edge computing.

 

WHY EDGE COMPUTING IS NOT JUST COMPUTING AT THE EDGE

Edge computing employs a fundamental distributed processing architecture, not just replicated data centers in remote locations.

Placing replicated date centers at the network edge enables a company to run perhaps hundreds of database processes simultaneously.

True edge computing, employing a deeply distributed architecture, runs tens of thousands to tens of millions of database processes simultaneously.  Edge computing atomizes conventional software infrastructure into a granularity that makes edge computing a “difference of kind.”

Edge computing delivers its promise via a distributed architecture that can utilize a heterogeneous hardware mix of servers, embedded devices, and mobile devices such as tablets and phones.

In true edge computing, the requirement for conventional, legacy data center software infrastructure disappears.

There is no need for Oracle or any other data center commercial DBMS.  Ditto for VMware, conventional data center security products and middleware.

Edge computing delivers real time processing, on virtually any hardware, at the network edge because it is built with an entirely different software technology stack.

The edge computing software stack is massively optimized to eliminate I/O wait states. The delay from hitting the enter key to parsing over 100 million records in a query is imperceptible.

The differences between computing at the edge and true edge computing are seen in the business outcomes.

If you are computing at the edge, nothing much changes except some network delays are reduced.

However, with edge computing, everything changes:

  • Applications run 1,000 to 1 million times faster
  • Apps that used to run in large cloud data centers, now use bare Unix instances that reduce “value add” cloud costs to zero
  • Storage is reduced 80-90% because of the elimination of RDBMS legacy constraints
  • Applications that once took 2-3 years to build from scratch, now take a single business quarter
  • IT costs are reduced 50% while applications are delivered in a fraction of the previous time

While these outcomes are impressive, the real power of true edge computing comes from what it enables, not what it eliminates.

Legacy batch systems, with 40 year old patched (or even lost) source code can now be rebuilt in weeks and made to run in real time.

New digital applications can be imagined, built, tested, placed in production and in customer’s hands or on their phones in a single business quarter.

Two large corporations, each with intractable legacy systems, can deliver a real time customer experience, via a partnership, to blend one’s products and the other’s distribution capabilities in real time, in a single business quarter.

The outcomes are quite different.  Computing at the edge kicks the can down the road where nothing much changes.  Edge computing delivers customer intimate apps, in real time, at a fraction of legacy world costs.

True edge computing enables true digital transformation.
