The opportunities of network-as-a-service

0:03 foreign

0:08 Telecom TV I'm Guy Daniels director of

0:11 content

0:12 enabling Network as a service

0:14 functionality is becoming an important

0:16 capability for many csps as they map out

0:19 their future technology and services

0:21 roadmaps we're here to discuss the

0:23 potential value of Nars 2 operators is

0:26 Raj yaveka who is Chief technology

0:29 officer for Juniper Networks hello Raj

0:32 very good to see you now as we know

0:34 there are many different views and

0:36 definitions of network as a service so

0:39 how do you define US

0:42 that's a very good question I think I

0:45 just want to give you some history of

0:47 how the network as a service came about

0:49 it really started with software defined

0:52 networking as a principle where people

0:54 wanted to centralize a control plane to

0:58 configure a layer to their three

0:59 switches then it evolved to what we call

1:02 SD band as a service today where we went

1:04 away from circuits to more providing a

1:06 tunnels On Demand right and then sassy

1:09 is adding security to that that's how

1:12 the network as a service has evolved and

1:15 it has been now considered equivalent to

1:18 pay as you go service but that is not

1:20 sufficient because at the same time the

1:22 last few years networking has evolved

1:24 rapidly because of the hyperscalers

1:27 providing public Cloud so you have

1:29 public Cloud they have VPC networking

1:31 within public Cloud you have Edge Cloud

1:33 you have Metro or van you have on-prem

1:38 both virtual oral networking and

1:40 physical networking then of course you

1:42 have private 5G Wi-Fi and so on so

1:45 really if you want to consider Network

1:46 as a service you have to consider it

1:48 across all these domains

1:50 so I look at Network as a service

1:54 as a on-demand creation and termination

1:57 of end-to-end networks across all these

2:00 domains in minutes with security

2:03 functions enabled and with proper

2:07 performance isolation and security

2:09 isolation

2:10 thanks Raj now as you explained there

2:13 the industry is going through this this

2:15 Evolution this deep transformation with

2:17 Cloud Edge Computing and more

2:19 distributed workforces and applications

2:22 why therefore should operators consider

2:25 adopting a network as a service model

2:28 I think that's a very uh good point

2:31 right because if you look at Enterprises

2:33 due to public Cloud first of all they're

2:35 getting used to this consumption-based

2:37 module

2:38 right as you said we are going to a big

2:42 transformation with distributed

2:43 Workforce people come and go they join

2:45 the networks and go they are no longer

2:46 sitting in offices you have distributed

2:49 applications SAS Transformations all of

2:52 those if you look at it the Enterprises

2:54 are looking at the public Cloud as a

2:55 model where the network whether in the

2:58 VPC inter VPC connecting to the cloud

3:00 it's all software driven it's all

3:03 virtual it's API driven they expect the

3:06 same model to be enabled across all the

3:09 domains they have to deal with it may be

3:12 Wi-Fi it could be private 5G it could be

3:14 on-prem data center networking it could

3:16 be Cloud connectivity and so on so

3:18 that's number one number two I think

3:23 um if you look at it from operatives

3:25 perspective this is a opportunity for

3:27 them to create new sources of soft

3:29 Revenue

3:31 because today they are getting more and

3:33 more relegated to be bit pipe providers

3:36 if you can enable such Services

3:39 on-demand Services across these domains

3:42 you can start monetizing

3:44 and that's a consumption-based model is

3:46 software driven but underlying physical

3:48 infrastructure continues to play an

3:50 important role to enable that

3:54 finally The Operators also have to be

3:56 very much aware of the fact that

3:58 hyperscalers are moving closer and

4:00 closer to the edge of the network

4:02 and closer to the Enterprises

4:05 so if you want to continue to be

4:07 relevant you have to provide services on

4:12 part with hyperscalers to the

4:13 Enterprises so they continue to be your

4:15 customers and this is very important in

4:17 the context of what has happened if you

4:19 look at it from nvnos perspective

4:22 The Operators already enabled mvno as a

4:26 model to allow virtual end-to-end

4:28 Network to be residing on top of the

4:30 physical Network so any third party

4:32 could provide a virtual network service

4:34 but that is not sufficient because

4:36 that's still going back to providing

4:38 only bit pipes

4:40 what network as a service enables or

4:42 allows operators to do to really offer

4:45 value-added services based on security

4:47 isolation performance acceleration using

4:50 end-to-end slicing so that they can

4:53 start

4:54 generating revenues from Enterprises for

4:57 different types of services

5:00 Raj this is all very encouraging news

5:02 but how far are we from achieving

5:04 Network as a service and what are the

5:07 key activities happening now around this

5:09 technology that's a very good question I

5:12 think we are evolving we are not dead

5:15 yet but we have made a very good start

5:17 so for example Beyond sassy and his

5:20 demand which are really truly a network

5:22 as a service being delivered today right

5:24 people are beginning to look at

5:26 extending that model to Edge cloud

5:30 to the kubernetes based Overland

5:32 networks both in Cloud as well as

5:34 on-prem to Wi-Fi and so on so I think

5:38 there are multiple efforts such as an

5:40 industry standardization such as nepheo

5:43 Encore

5:44 which is age multi-cloud orchestration

5:47 project in Linux Foundation uh you have

5:49 kubernetes based networking which allows

5:51 you to really

5:53 automate uh intent driven configuration

5:56 and operation of the networks so those

5:59 are the new developments which are

6:00 happening in different domains the

6:03 problem is that each of these domains is

6:04 being addressed in isolated values

6:07 this is where an opportunity is there to

6:09 really Define Network as a service which

6:12 is uniformly defined API driven across

6:15 all these domains starting from 5G Edge

6:18 Metro Cloud as well as on

6:22 and what are the market opportunities

6:24 for operators and why are you and

6:27 Juniper excited about its future

6:31 so operators are very important part of

6:34 our customer just like hyperscalers are

6:36 big customers of ours operators

6:38 traditionally have been a big customers

6:40 with delivered products and services to

6:42 them and we look at this as an

6:44 opportunity for operators to continue to

6:46 evolve and take advantage of the market

6:48 transformations

6:50 we are excited about it because we have

6:53 this strategy to deliver what we call

6:57 client to Cloud secure Azure networks

7:01 which is cloud managed AI Ops driven

7:04 and we started with missed Wi-Fi

7:07 right where we it's a cloud managed apps

7:10 driven assured service we extended that

7:13 to campus and Branch networks and access

7:15 networks now we are extending that to

7:17 Cloud Metro and data center and private

7:20 5G and 5G

7:22 when you do that I think you start

7:24 defining a uniform architecture uniform

7:27 platform client to Cloud which is API

7:31 driven which allows you to abstract out

7:33 Network as a service no matter which

7:35 domain you are in

7:36 delivering on

7:38 Enterprises get to see it as a client to

7:40 Cloud Model so they can now start

7:43 consuming Services across all these

7:45 topics without having to worry about

7:47 they get security they get that

7:49 performance Assurance but also they get

7:52 On Demand creation and termination of

7:55 networks so we are excited that we can

7:56 enable our customers operators to start

7:59 delivering the services in a uniform

8:01 manner

8:02 now for mobile service providers that

8:05 already deliver Services via the cloud

8:07 how is this Evolution different for the

8:10 mobile service operators is important to

8:12 understand that they have not just think

8:14 about the mobile networks or radio

8:16 Access Network

8:17 they have to start thinking about their

8:19 applications their end users are using

8:22 applications Enterprises are using

8:23 application which are client to Cloud

8:25 they go across all these domains so the

8:28 concept of slicing has to be now end to

8:31 end because if you can create the slices

8:33 of the networks on demand and deliver

8:35 services using that you can protect the

8:38 traffic you can provide

8:39 satisfy use cases that we have not

8:42 thought for example an Enterprise might

8:45 say or some network provider might say I

8:48 want to create a network end-to-end

8:51 network which is isolated from the

8:53 production environment so that I can try

8:55 out new security functionality you have

8:57 to be able to do that you have to be

8:59 able to do end-to-end networks which are

9:01 specific to a particular application

9:03 so that you can isolate that application

9:05 from other applications other traffic

9:08 those kind of possibilities have to be

9:10 considered not just in the context of

9:12 mobile network but across the domains

9:16 because applications are distributed use

9:19 cases are distributed and requirements

9:21 are distribute

9:22 that's msps but why should Enterprises

9:26 also be excited

9:29 I think the Enterprises have to be

9:30 excited because as I said earlier at the

9:33 beginning right you have distributed

9:35 Workforce you have distributed

9:37 applications with SAS Transformations

9:39 increasingly use up the cloud either

9:41 with public Cloud Edge cloud or even

9:44 on-prem Cloud across all these things

9:46 the old model of I submitted ticket and

9:50 debate for services to be enabled does

9:52 not work you will want more API driven

9:55 virtual network software driven

9:57 networking even though underlying

9:59 infrastructure still has to be supported

10:00 in physical appliances given that

10:03 enterprises now can ask for

10:07 such on demand pay-as-you-go model where

10:11 you do you are able to add a new

10:14 Workforce if you have a employee who

10:17 moves from one place to another but

10:19 still wants to connect to the network

10:20 all those connectivities should be

10:22 enabled on demand very easily and

10:25 they're getting used to that using the

10:27 public clouds so they expect that model

10:29 to be extended everywhere and that's why

10:31 I think Enterprises are excited about

10:33 this ability to consume networks in a

10:36 uniform manner Cloud to a client to

10:38 cloud and in Azure map

10:40 well final question Raj for operators

10:43 that want to explore this journey where

10:45 do you recommend that they start

10:47 that's the excellent question I think we

10:49 have multiple of these initiatives and

10:52 they need to start looking at it as a

10:54 end-to-end problem

10:56 which means think of a uniform platform

10:58 layer that abstracts out underlying

11:01 connectivity no matter where you're an

11:03 edge Cloud you are in public Cloud you

11:06 are in a Metro or on-prem and Sumo if

11:09 you can think of that uniform platform

11:12 layer that exposes apis by the way 3gp

11:15 recently announced that they are going

11:17 to create such a service creation model

11:18 agile on demand using a uniform platform

11:22 layer but that's for the mobile networks

11:24 I'm saying do that across the all of

11:27 these domains you can use kubernetes as

11:29 a very good foundation for that because

11:31 it provides this intent driven

11:33 configuration automation deployment

11:35 automation some of the industry

11:38 initiatives such as nephew MCO and

11:40 kubernetes itself are very much ripe to

11:44 be exploited so operators should start

11:46 from that but take the end-to-end view

11:48 and take advantage of slicing you are

11:51 looking at doing slicing if you look at

11:53 mvno that's a very primitive model for

11:57 providing overlay Network to a customer

12:00 from the operator right it doesn't do

12:03 much but if you combine that kind of

12:05 model with end-to-end slicing where you

12:07 could have slices per application slices

12:10 per customer slices per even subscriber

12:14 and each slice is isolated from

12:16 performance and security point of view

12:19 then now suddenly you are making your

12:22 network a lot more valuable from which

12:25 you can derive revenues so think of

12:27 investing in end-to-end slicing think of

12:29 investing in this uniform platform layer

12:32 I'm talking about which allows you to

12:34 have API driven service creation across

12:37 all these domains that could be a great

12:39 start great advice Raj it was a pleasure

12:41 talking with you thanks so much for

12:42 joining us today and sharing your views

12:44 on network as a service

12:47 thank you guys it was a pleasure
