3、ated the pace of digitization.Satya Nadella,CEO of Microsoft,has famously stated that we have witnessed multiple years worth of Digital Transformation being accelerated in just a few months.Today,the world is inarguably going digital.One of the consequences of digitization is more data.IDC,in its“Da

4、ta Age 2025”report,predicts that the worlds data will grow to 175ZB by 20251.This data will be stored in the core(traditional and cloud data centers),at the edge,and on edge endpoints like PCs,smartphones,and IoT devices.Moreover,30%of this data will be consumed in real-time.This is,in part,due to a

5、dvances in technology.Data transfer speeds with 5G are up to 100 times faster than previous wireless generations,and latency typically decreases from 20ms to 1ms2.These new capabilities will increase data generation velocity and the ability to process it in real-time.Much of this real-time data is g

6、enerated and consumed by stationary devices:light bulbs,security cameras,home appliances.One-third of homeowners have increased usage of devices during the pandemic,including nearly half(46%)of smart door lock owners3.But a significant percentage are mobile:wearables in healthcare,connected vehicles

7、,sensors that track and monitor supply chains.As of November 20204,in the U.S.alone,45%of web traffic originated from mobile phones.This explosive growth of devices has radically changed the definition of a user,with machines and scripts and software now acting in a role once delegated only to human

8、 beings.This growth is expected to continue.At the same time,the number of people using this technology continues to expand.In 2019 there were 4.9 billion Internet users.By the end of 2022 that is expected to grow to 6 billion.And by 2030,experts predict that 90 percent of the projected world popula

9、tion8.5 billion six years of age and older will be digitally active5.Many of these users now rely on digital services in almost every area of their lives.For example,telemedicine use grew a staggering 6000%during the pandemic6.The pressures and demands of a distributed,digitally active society combi

11、 that the rise and evolution of edge computing will inevitably follow the arrival of the Third Wave of the Internet.As we know,Internet transformation drove the world towards the PC and Internet era.Cloud computing and adoption of smartphones introduced the Mobile Internet era.Now we are entering a

12、third era,the Internet of Moving Things.The challenges emerging in this era are driving change into the edge ecosystem,moving from static and closed Edge 1.0 to open and autonomic Edge 2.0.This process is like the evolution from single-celled organisms to complex organisms.For example,in the early s

13、tages of the cloud movement,a few large public clouds and content delivery networks(CDNs)dominated the Internet application delivery and digital service distribution.These providers functioned as the centralized control points for the Internet application ecosystem,somewhat similar to the way the tw

14、elve cranial nerves function in a human body.As the cloud use case and ecosystem grows,we are seeing the need for digital services to make real-time decisions based on localized knowledge at the“edge”of the internet,akin to the way the autonomic nervous system behaves in human bodies.This is the evo

15、lution driving the edge into a new autonomic era.This is not surprising.Each wave of the Internet brought with it challenges which were addressed in part by edge computing.THE EDGE ECOSYSTEM HAS EVOLVEDThe Third Wave of the Internet4FIRST WAVE:EDGE 1.0 Tim Berners-Lee,the inventor of the World Wide

16、Web,foresaw the congestion challenge related to the transfer of large amounts of web content over slow links that the Internet users would face;he called this issue the“World Wide Wait.”The focus of the dominant paradigm at the time was,appropriately,on distributing the relatively static web content

17、 or web applications to get them closer to users to address the need for speed and redundancy.That need led to a set of key architecture tenets including physical Point of Presence(PoP)close to end users,content caching,location prediction,congestion avoidance,distributed routing algorithms,and more

18、.SECOND WAVE:EDGE 1.5The advent of Web 2.0 coupled with the emergence of public clouds and SaaS solutions introduced new architectural tenets.Applications became the primary form of content over the Internet.As such,the distributed edge could not persist in its nascent form:it had to evolve along wi

19、th the application architectures it delivered while under increasing pressure to secure a growing digital economy.With so much of the global economy now highly dependent on commerce-centric applications,security services quickly became an add-on staple of CDN providers,whose existing presence around

20、 the globe stretched closer to the userand thus resolved threats earlierthan the cloud and traditional data center.These services were built atop the infrastructure put in place to distribute content and therefore represent closed,proprietary environments.THIRD WAVE:EDGE 2.0 Today,applications are n

21、o longer the“passive”routing destinations of the delivery network but are instead active participants.For example,with Kubernetes-based distributed applications,the application logicpacked inside a containercan dynamically move to any appropriate compute location with a supporting Kubernetes stack.T

22、his is in direct contrast to the architecture principles upon which early edge solutions were built.That is,they are rooted in a time when contents(or applications)were static entities associated with the physical locations.Such edge solutions presume that the content delivery network alone function

23、s as the“intelligent platform”to connect users to applications,while the applications(and users)remain passive“endpoints”to the“intelligent platform.”This approach is no longer the best architectural way to connect users to content or applications.Users,as well,have evolved.Not only is their digital

24、 sophistication and appetite for digital engagement light years ahead of where they were when the first CDN started in 1998,but The Third Wave of the Internet5technology has forced a change in the definition of what they are.Today,a“user”might well be a machine,a script,or an automated service actin

27、ed is the definition of application(from a static instance residing in a fixed location to“movable”container units),user(from a human user to an intelligent“thing”),location(from an IP-address to a logical identification),and the use cases that the edge aims to support(from content delivery to dynam

28、ic application distribution and real-time decision making at Edge).Digital transformation and IoT is driving new requirements for digital experiences that result in the need for application distribution,real-time intelligence and decision making at the Edge.As such,edge computing is becoming a key e

29、nabler of digital transformation in the industry.According to the 2021 State of Application Strategy report7,76%of organizations have implemented or are actively planning edge deployments,with improving application performance and collecting data/enabling analytics as the primary drivers.EDGE 1.0Con

35、ts that“by 2023,there will be more than three times more networked devices on Earth than humans.About half of the global connections will be machine-to-machine connections and the M2M space will be dominated by consumer-oriented things in smart homes and automobiles.”Due to the past separation of IT

36、 and OT(operational technology),although cloud computing has brought about a great increase in computing power,the addition of“things”still introduces challenges to the network architecture under the cloud model.In the mobile IoT environment of the Edge 2.0 era,IT and OT will be converged and have m

37、ore powerful intelligent sensing and automation capabilities.In other words,in addition to the centralized data processing enabled by cloud computing,the network edge will bring together an abundance of devices and data,and provide tremendous computing power close to the endpoint,thereby unleashing

38、great business value.For organizations to take advantage of Edge 2.0 and reap its rewards,one of the things they will need is an application distribution platform centered around holistic application distribution and based on a different set of technology design principles.An Edge 2.0 application di

39、stribution platform must be based on the following key design principles:Unified control plane For an Edge 2.0 application distribution platform,“edge”can be any physical or logical environment ranging from user endpoints to public clouds.A unified application control plane ensures the common defini

40、tion of security policies,data location policies,and user identity management across different environments and enforces execution via integration with automation and orchestration tools.Application-oriented An Edge 2.0 application distribution platform will integrate fully with application life cyc

41、le management tools.Application security policies,data location policies,identity management,and resource orchestration are“declared”via the unified control plane and enforced in any environment the platform runs inside.The Edge becomes a“declared property”of the target application(resulting in ever

42、y application having its own“personalized”edge)and is“executed”by the platform without required manual provisioning.Developers can simply focus on the application logic,application interactions(APIs),and business workflows without worrying about managing infrastructure or locations.The Third Wave of

43、 the Internet7Distributed security embedded in the platform In an Edge 2.0 application distribution platform,application security policies are defined in a common way via the unified control plane.They are distributed for enforcement in every environment the application runs inside.Security capabili

44、ties embedded directly in the platform(for example,encryption and best-of-breed bot detection)allow these security functions to move with the application by default.Distributed data processing and embedded analytics An Edge 2.0 application distribution platform becomes a global fabric for applicatio

45、n logic and a global fabric for data processing and analytics.Any digital service requires both data and application logic,but the location for storing,processing,and transforming data should not be required to be the same as where the application logic resides.The data location should be specified

46、independently as a set of platform level policies determined by factors such as data gravity,regulations(PCI,GDPR,and others),and the relative price/performance of processing.Similar to security policies,data location policies should be“declared”by the users via the unified control plane and enforce

47、d by the platform in any environment.An Edge 2.0 platform has a role to play in other data management policies,such as data lineagestoring details on data as embedded attributesin addition to having a set of built-in operational capabilities for observability,telemetry streaming,ML tools,and ETL ser

48、vices.Software-defined elastic edge For an Edge 2.0 application distribution platform,the“edge”is no longer defined by physical PoPs in specific locations.Instead,it is defined dynamically by the Edge 2.0 control plane over resources that exist anywhere a customer may desire:in public clouds,hypervi

49、sors,data centers or private clouds,or even physical machines in”remote”locations unique to their business.The connection network capabilities are also delivered in a software-defined way overlaid atop private or public WAN infrastructure without herculean effort to assemble and configure.It will re

50、spond to the target applications“declaration of intent”by delivering a customized,software-defined elastic Edge at an applications request.“Edge”and all that it establishes for the application as part of that declarationwill become a simple,easy-to-use property of the application.The Third Wave of t

51、he Internet8Hardware-optimized compute The advancement in processor and chipset technologiesspecifically GPU,DPU,TPU,and FPGAs that are emerging in capability and capacityhas made it feasible for specialized compute to significantly optimize resource use for specific workload types.An Edge 2.0 appli

53、or special application security and networking services that an application needs.Hardware awareness in an Edge 2.0 application distribution platform offers intriguing benefits for the creation of special-purpose application-facing intelligent“industrial systems”and thus boundless possibilities for

54、establishing attractive IoT solutions where real-time processing is needed locally.For example,an EV charging station can serve as a data aggregation point of presence for the copious amounts of data generated from the EV sensors,or an autonomous vehicle powered by Android OS can behave like a mobil

55、e data center running continuous hardware-assisted self-diagnostics.Navigate the Third Wave of Internet with Innovative Application Delivery The distributed and real-time intelligence enabled by the Edge 2.0 application platform will play a central role in tomorrows digital world.For most enterprise

56、s,this means to reimagine their application delivery models.Current application and service delivery is built around a centralized model where application logic is centrally located.Application logic is hosted in public cloud or private data centers.In the Edge 2.0 era,the infrastructure,data,and ap
