Don’t get left behind as the client-to-cloud journey rolls onward.

In this talk from AI in Action, Juniper’s Sujai Hajela says that in order to drive user experiences, you must now be able to look at everything across the network, which Juniper refers to as client-to-cloud. The fact is, Juniper is on a mission to unleash the network for the next decade. Listen as Sujai talks about why you should join us on this journey and make us part of your extended engineering team.

0:00 missed and now miss juniper the whole

0:02 philosophy of

0:04 user experience being the new uptime

0:07 came from customers such as you you are

0:09 the folks who have guided us

0:11 who've helped build this company and

0:13 always say this company and the ai

0:16 driven enterprises juniper is all about

0:19 being built by you

0:22 for you

0:23 what does that mean and i'm very i'm for

0:25 those of you who know me i'm very very

0:27 clear

0:28 in my philosophy what does that mean

0:30 number one

0:31 we are on a mission

0:34 to unleash the network for the next

0:35 decade

0:36 you all

0:38 are request your humble support to be on

0:41 this journey with me no i'm not going to

0:43 give you any coding exercises right now

0:46 but i'm definitely going to be coming to

0:47 you for guidance

0:49 because the second part about our

0:51 philosophy as we drive user experience

0:54 is very simply when you look at us when

0:57 you look at my team when you look at

0:59 sudhir tom sunani sanjoy jacob even our

1:02 ceo rami even our cio for us we want to

1:06 be a part of extended engineering team

1:09 that's the way it works now

1:12 as i set the stage for user experience

1:16 what is extremely critical

1:19 is as you drive user experience as you

1:22 drive a level of assurance which is

1:24 unheard of in the industry

1:26 you cannot just do it on parts of the

1:28 network you could start with wi-fi

1:31 extend to wired go to sd-wan and to the

1:34 cloud you have to be able to look at

1:36 everything across the network which is

1:39 what we refer to as client to cloud

1:44 there's a key reason when i speak about

1:46 user experience and i speak about client

1:48 to crowd i bring up and that came from

1:51 one of our customers who's actually

1:52 sitting right here today and he's going

1:54 to share some of his experiences

1:56 they said sujai it is fine when you

1:59 speak about user experience let's say

2:01 where's leslie i always oh let's again

2:04 she's on email while i'm speaking can

2:05 you guys believe it

2:07 anyway

2:08 okay

2:10 let's see if she has a problem while

2:12 she's trying to connect to the network

2:14 she can call network i.t and they can

2:16 try to do something about it

2:18 but then as that erstwhile company once

2:20 told me three years back branno maybe

2:23 four years back

2:24 so jay a user can complain

2:27 but a robot

2:29 when it fails

2:31 it doesn't complain

2:32 it stops working

2:34 as that robot stops working

2:37 10 other robots around it stopped

2:38 working too

2:40 and in less than five minutes

2:42 you've just taken down a distribution

2:44 center and probably impacted 25 to 50

2:46 million dollars of business

2:49 this is the business why assurance

2:51 becomes so critical client to cloud

2:54 fully assured

2:55 but as you start embarking on this

2:58 journey for client to cloud

3:00 there are two things which become

3:02 extremely critical

3:05 and i mean it

3:06 number one it's all about a cloud native

3:09 architecture i know everybody in this

3:11 room is like okay man here he go again

3:13 yet another cloud native architecture

3:15 but let's just speak about very simple

3:18 principles

3:19 we were the first ones in 2015 2016

3:22 brock friday sitting right there he said

3:24 sujay over my dead body will you write

3:27 monolithic code architectures again what

3:30 are those architectures by the way he's

3:32 the one who came out with that in 2004

3:34 because he was the co-founder of

3:35 airspace too

3:36 but ignoring that what was those

3:38 architectures monolithic architecture

3:40 put on a controller and then brad when

3:42 crack hap sorry brian when crack

3:44 happened you couldn't do much about it

3:46 you had to upgrade that whole code on

3:48 the controller a micro services based

3:50 architecture which we introduced was

3:52 very simply you disaggregate all the

3:55 functions

3:56 into many task workers and they all are

3:59 working one is association one is

4:01 authentication one is dhcp one is

4:03 location one is guest

4:05 you start looking at these and as they

4:07 start working if they have a problem

4:11 you just change that part of the

4:13 function out

4:14 you patch it up you're done your service

4:16 mic does not get impacted

4:20 that was the first most important thing

4:22 about a cloud native architecture

4:25 just a raise of hands if i can how many

4:28 of you remember

4:29 crack k-r-a-c-k

4:32 okay

4:34 keep your hands raised

4:36 if you were able to remediate that issue

4:38 in a week

4:40 so you fixed it in a week any raise of

4:42 hands where it took you months to

4:44 remediate the crack issues across your

4:45 network

4:47 and you're not the only ones they're

4:48 many it's okay i'm not gonna call out

4:50 who you work for but now you're on the

4:53 bright side of miss juniper so you're

4:55 fine but if you look at the crack issue

4:58 when that happened

4:59 we have customers

5:01 who were trying to remediate crack

5:03 not for weeks not for months but for

5:06 years

5:07 the miss juniper universe of crack

5:11 was remediated in less than eight hours

5:15 globally

5:16 welcome to the cloud native architecture

5:19 the second thing which i always speak

5:20 about and many of you know this

5:23 we say christmas comes to miss juniper

5:26 every wednesday

5:28 because guess what happens every

5:29 wednesday

5:30 there's a production push on the cloud

5:33 this is a cloud native architecture

5:38 the second part

5:39 is

5:40 to deliver on that client to cloud that

5:42 assurance that maniacal assurance beyond

5:44 cloud native you also need a

5:47 well-stocked ai toolkit

5:49 it's extremely critical but there are

5:52 certain things i just want to make sure

5:54 we understand

5:56 to be able to leverage ai i mean there's

5:58 a lot of ai washing in the industry

6:01 we frankly feel honored that we have the

6:03 partnership with customers and prospects

6:04 such as yourself and are guided well by

6:06 industry analysts who keep us honest on

6:09 what's happening but this is one key

6:11 difference which is very important

6:14 ai for us was built from the ground up

6:17 if you think about a tesla

6:19 it was built from the ground up where is

6:21 sudhir

6:22 sudhir

6:23 just recently converted to a tesla after

6:26 five years of convincing him

6:28 but

6:29 if you think about it it was built taran

6:31 from the ground up to be an eevee okay

6:34 you cannot there are many amazing cars

6:37 whether you are a toyota honda benz bmw

6:40 you break your pick you cannot put an

6:42 ipad on these cars and call it an ev

6:46 it has to be built from the ground up so

6:48 when that ai toolkit is talked

6:51 bob friday built the architecture from

6:53 the ground up to be ai driven

6:57 now

6:58 as we started looking at this we

7:00 introduced the first

7:03 network assistant to the industry

7:07 marvis

7:09 how many of you heard about marvis if i

7:11 can just get a raise of hands

7:13 wow that's pretty cool maybe after the

7:15 session we'll talk and i will give you

7:18 the science that went behind the naming

7:20 of marvis

7:22 some of you may know it already but as

7:24 you start looking at marvis the key part

7:26 why we did this

7:28 was if you speak to bob friday

7:31 to explain to him what is ai in a

7:33 sentence he will say

7:36 i train the machine

7:38 to think like a human being

7:41 i train the machine

7:42 to sit down with network i.t and huddle

7:46 together to solve a problem that's

7:48 marvis

7:50 when you start talking to marvis more

7:51 and more

7:53 you can ask very simple things i mean

7:55 many of us have had these you know

7:57 issues happen in a network we all huddle

7:59 together there's a conference call we

8:01 suddenly find out that we don't even

8:03 know where the problem is we don't know

8:04 what's the blast vector we don't know

8:06 who's impacted

8:08 simple questions difficult answers

8:10 call up markers bring marvis bring it in

8:12 and say hey how's my network doing

8:15 you can ask walk up to marvis and say

8:17 hey

8:18 taka is complaining in japan what's

8:21 going on with his issue simply said

8:24 marvis comes and says

8:25 having a roaming issue

8:27 great

8:28 now

8:29 this is something by the way we i know

8:32 we had some servicenow folks

8:34 in the audience and they were moved up

8:36 thank you so much hi sanjeev

8:38 so if you think about it this is

8:39 something which we learned from

8:41 servicenow is where i say company built

8:44 based on the feedback we get from

8:46 customers

8:47 they had this program and please allow

8:49 me to say it

8:50 about program called race to zero

8:53 and this was how do you maniacally

8:55 reduce the trouble tickets from over a

8:58 hundred per month to they wanted zero i

9:00 was a startup i said yes i can do it

9:02 we're down to at least two or three so

9:04 that's not bad but fundamentally they

9:06 weren't the ones who said train marvis

9:09 that every morning all i want to say is

9:11 how many unhappy users are there in your

9:13 network you know exactly and you start

9:15 getting proactive right you start

9:17 getting proactive and trying to address

9:19 these things so if you think about

9:20 marvis it was literally bringing it as

9:23 bringing ai as an interface where you

9:26 have

9:26 a digital concert sitting next to you

9:29 helping you with what's going on we're

9:31 not going to talk about all the back-end

9:32 stuff it does i'll leave that for sudhir

9:34 when he comes for his demos

9:36 but now

9:38 people ask and say ai really is your ai

9:42 real ai

9:43 and i say two simple things

9:45 number one

9:48 when you christian have an issue on your

9:50 wireless network

9:52 or a wired network or an access network

9:54 or now sd van

9:56 when you call juniper

9:59 customer support

10:01 the first person

10:03 who takes care of that call

10:06 is marvis

10:09 this is a religion

10:11 in our organization

10:13 and if marvis is not able to answer if

10:15 it's able to answer the question

10:16 fantastic if marvis is not able to

10:19 answer the question here is another huge

10:21 change which we have done in our

10:23 organization

10:24 the data science team

10:26 is co-located with the customer success

10:29 team

10:30 so what happens now marvis is not able

10:33 to answer the question it gets escalated

10:35 to customer success the customer success

10:38 person sits with the data science team

10:40 and as the customer success person is

10:42 remediating the problem the data

10:44 scientist is modeling that problem back

10:48 into marvels

10:49 this is ai driven support i know this

10:51 slide may become a bit difficult to

10:54 understand sometimes but this is the way

10:56 we track the efficacy of marvis

10:59 fundamentally in very simple terms

11:01 many of you have seen the growth of

11:03 juniper mist i mean ramya ceo just spoke

11:05 about enterprise being our largest

11:07 vertical in q1 within juniper

11:10 but think about it

11:11 our number of network devices under the

11:14 miss cloud

11:16 have gone up not a hundred times not a

11:19 thousand times not a ten thousand times

11:22 way beyond that

11:24 but here's the best part

11:26 number of customer success engineers

11:29 less than 10 compared to two years back

11:32 this is ai driven support so when i hear

11:35 about hey you know i was just here and

11:38 another company came in which is orange

11:39 and color another company came in which

11:41 has this blue thing in their slides

11:43 they said the same thing

11:45 and i just say okay why don't you go and

11:46 ask them

11:47 how much do they use their own ai engine

11:51 to troubleshoot their problems

11:53 then we'll have a discussion so very

11:55 simply and i'm totally totally totally

11:57 out of time

11:58 but here's something which i wanted to

12:00 say

12:00 i started this discussion with client to

12:02 cloud

12:04 i spoke about things you probably

12:05 already know cloud native ai driven

12:09 but here is

12:10 the most important part

12:13 i am on a mission

12:15 my team is on a mission

12:17 our ceo is on a mission our cio supports

12:20 us on that mission and many of you in

12:22 this room i know who have been our

12:24 customer supporters on this mission

12:26 but this mission is about a journey

12:29 to unleash the network for the next

12:31 decade

12:33 whether it's wi-fi shyt we need to start

12:36 looking at sd-wan yes wi-fi wired that's

12:38 old news now we need to start looking at

12:40 that but as we go over this journey

12:44 i

12:44 really humbly request you all

12:48 to be a part of this journey

12:50 because guess what

12:52 you know

12:53 maybe after 20 30 40 years when you're

12:55 in hawaii having a drink and you're

12:57 retired

12:58 don't you want to leave the legacy that

13:00 you assured the network for the next

13:01 decade because let me tell you people

13:04 say ah that's not for me

13:08 that is for you

13:10 we are the people who run the network

13:12 we are the ones who make these business

13:14 outcomes happen

13:16 and to get this reliability and the

13:18 agility of outlook getting the business

13:20 services

13:21 in production

13:23 we need to think about the network for

13:25 the next decade so with that i humbly

13:28 request you to partner with us on this

13:30 journey

13:37 you
