0:00 But, is it fair to say that?

0:02 Edge Computing will replace Cloud Computing ?

0:04 Hello friends.

0:05 Welcome to IT k Funde

0:06 Your own channel where we make I.T. interesting for

0:08 everyone. And in this video,

0:10 we will understand about Edge Computing,

0:12 after cloud

0:14 computing, rocking the IT world for the last decade.

0:16 Now is the time in Edge Computing is picking up pace.

0:20 As we are seeing the Advent of IoT (Internet of things)

0:23 and 5G network so in this video will understand.

0:27 What is Edge Computing?

0:28 Again with a real-life example,

0:30 we will understand why we needed and how exactly it

0:34 works.

0:34 So without further ado,

0:35 let's get started.

0:37 Thank you,

0:51 So lets take an example

0:53 suppose this is a new startup named ABC

0:56 And this guy is the owner of this startup

0:58 Now to manage the financials of this particular startup,

1:02 he contats a consultancy,

1:04 and accountancy firm XYZ and over the course of the

1:09 next 4-5 years.

1:10 This guy used to manage all the financial data within

1:15 its company and then send it over on email or over the

1:18 phone. Or he used to take advice from this consultancy

1:22 and accountancy firm.

1:23 And this accountancy used to maintain all the balance

1:26 sheets P&L,

1:27 and profit & loss statements.

1:29 All those things for this particular startup but in the

1:33 span of five years,

1:34 this startup has grown into a big enterprise,

1:38 with thousands of employees.

1:39 And now,

1:40 the business model has become complex the financial

1:43 information, which is getting processed has become

1:45 much more complex.

1:46 It has grown into a complex model and now managing

1:50 this financial health of this company is not possible

1:54 with this remote consultancy.

1:56 So what happens that this startup talks to this particular

2:01 consultant company and ask that if we can have some

2:05 dedicated service with us all the time because we

2:08 need to take crucial business decisions day in and day out

2:10 out, and we need someone to guide us as far as the financials

2:14 are concerned.

2:16 So this particular head of the company deploy 1 chartered accountant full time

2:20 in this firm

2:23 And this particular person who is sitting here

2:26 his role is to guide the CEO of the company

2:30 in day-to-day activities,

2:32 as far as financial health,

2:34 is concerned or managing

2:36 the financial data is concerned,

2:38 or taking some crucial business decisions are concerned,

2:42 this particular chartered accountant helps in that so its become very quick and fast

2:46 And this particular chartered accountant also takes all the data

2:49 and send it back to the firm.

2:52 So that the firm manages,

2:54 the overall health of the company.

2:56 So yeah,

2:57 this is a layman example or a real life example of cloud computing

3:01 So, if you see this as a system and see this as a cloud

3:06 provider so what used to happen is all the data in the

3:10 processing used to go to the cloud and come back to

3:13 the. you know,

3:13 to that particular system?

3:15 Now, it was good for a while.

3:17 But now as we are moving into real time data

3:19 and IoT applications

3:21 this processing needs to be very quick

3:24 and that's where edge computing is a now coming into picture.

3:27 So what we'll do,

3:28 we'll now go and understand the architecture of edge

3:31 Computing, and we will now understand what "Edge" it provides

3:35 over cloud computing,

3:36 so friends now let's understand high level architecture overview of edge Computing.

3:41 What you see on this board is how edge computing is

3:45 playing a pivotal role in ensuring that all the devices

3:49 which are now processing iot data.

3:51 Real-time data,

3:52 Big Data are actually connected to the main cloud

3:56 data center

3:56 via these edge cloud computing platforms

4:00 But even before we understand this why we want it or why

4:03 we need edge computing is there are two main factors

4:07 one is latency and second is processing.

4:10 So if you have if you if you see sometimes when you were

4:13 talking to your Alexa device,

4:14 you might see some sort of a delay.

4:16 It might be because it is going to your cloud provider

4:20 getting the data from there and downloading it.

4:23 So how we can reduce these kinds of latencies because

4:26 it is just a device right?

4:28 Where you want to listen to your favorite song.

4:30 But what about if you are driving a,

4:33 you know,

4:33 a connected car,

4:34 or self automated car and there's an obstacle,

4:37 which is coming on the way on this car and suppose.

4:40 This car is now talking to the cloud,

4:41 you know,

4:42 the cloud provider.

4:43 The cloud data center to give the instructions back,

4:45 what they should do,

4:46 because there's a wall in front and you're sitting

4:49 back on the back seat terrified,

4:51 what should happen because these kind of systems can not afford these types of delays

4:56 Can have a very severe impact.

4:58 edge computing came into picture and the driving force

5:02 for these edge.

5:03 computing technologies is the 5G network.

5:08 because now you have all the speed is becoming so fast that

5:11 the data processing can be done very quickly.

5:14 And secondly,

5:14 IoT obviously

5:17 so basically we have three different players in edge computing

5:20 first is your cloud data center

5:23 second is your edge gateway server

5:25 and third, you see these blue logos

5:28 on top of every system.

5:30 These are edge clients

5:32 So what happens in edge computing is that there is a smart

5:35 device or edge client device,

5:37 which is installed on all these systems,

5:40 which record all the different kind of data,

5:42 which is being generated by these different devices.

5:46 And then it processes that data.

5:48 It has some sort of intelligence built-in within

5:51 and it has some storage capacity as well and then it processes the data

5:56 and then for higher workloads it sends it to the nearby.

5:59 Gateway server.

6:00 What is the difference between sending it here versus sending

6:03 it directly to the cloud?

6:04 Is, that your edge gateway server would be physically located,

6:09 very near to your device.

6:11 So that reduces the latency and increase the processing power

6:16 That's why all these gateways physically closer to

6:20 all these different systems.

6:23 Now where we are seeing the trend of edge computing coming

6:27 into picture everywhere.

6:28 where we see today

6:29 IoT coming into picture iot being used

6:32 like capturing the plant data or,

6:35 you know, transport intelligent Railways agriculture,

6:39 suppose, for example,

6:40 in agriculture.

6:40 There is a pesticide which,

6:42 you know,

6:43 which is causing harm to the to the crops.

6:46 And there is some some indication which has come in

6:49 and this particular smart device need to stop some

6:52 sort of a spray of the pesticide immediately, Power Systems

6:56 Wherein you have all these devices being installed

6:59 locally and we didn't,

7:01 you know,

7:02 these devices are getting locally installed.

7:04 And then this is sending data to your nearby physically

7:08 located Gateway server,

7:09 similarly connected car very important

7:12 No more and more different car manufacturers are

7:15 installing smart devices with in your car and even

7:21 for self-driving,

7:21 cars in future where

7:23 you will be sitting in your backseat

7:25 These kind of technologies would play a prominent

7:27 role, smart appliances.

7:29 You have some sort of iot installed,

7:34 like, your washing machine your mobile phones.

7:37 Are you smart devices like Alexa,

7:40 smart building now you have houses which are Smart Homes,

7:43 which we call it,

7:44 right? So as soon as you enter the house, the light would go on automatically.

7:47 All those kind of decisions will be enabled through this technology.

7:52 So these are some areas where we have edge computing

7:56 playing an important role or will play an important role in the coming times,

8:01 but there are other areas as well

8:04 so what drives this whole edge computing

8:06 as I said,

8:07 huge data getting generated.

8:09 Advent of 5G Wireless technology and you have iot

8:15 technology coming into picture

8:17 these technologies have enabled Edge Computing

8:20 faster processing because now you need faster processor

8:24 to take good decisions on time intelligence in hand.

8:28 So now you don't have to wait for your

8:31 Chartered accountant to,

8:32 you know,

8:32 give you something one week later.

8:34 When you have your chartered accountant sitting

8:36 next to you,

8:37 as we understood in our previous example,

8:39 similarly, your edge device is there,

8:41 right?

8:42 You add intelligent devices sitting within you and

8:44 you have your Gateway server,

8:46 you would have some racks of servers,

8:48 you know,

8:48 enabling it is.

8:49 Call it a small data center in its own sense,

8:52 which would be sitting very close to your appliance

8:57 or to your device.

8:59 Low latency.

9:00 Again, a very important factor of concerns on data,

9:04 security and privacy again.

9:05 This also is one of the things which are helpful,

9:08 because while the data is being sent to and fro many

9:12 times over,

9:13 you know, your Cloud,

9:14 there could be some hacks of intrusion and there could

9:18 be some data security breaches.

9:19 However, one of the downsides of one of the disadvantages

9:23 of using the edge computing is also security because

9:27 what if someone goes and directly hacks into these

9:30 systems directly where it is installed.

9:32 Maybe just get into your edge Gateway server.

9:35 So I would say security is a 50/50 thing.

9:37 We have something good about Edge Computing,

9:40 but there's a major concern around security and privacy

9:43 as well.

9:44 So, yes,

9:45 this is a high-level overview of what is Edge Computing,

9:49 and how it is becoming so popular.

9:50 Now you would see next ten years or so.

9:53 We will have its Computing in pretty much every area

9:57 between, which we know today and where we are using

10:00 cloud computing.

10:01 but is it fair to say that edge computing will replace

10:05 cloud computing?

10:06 I don't think so.

10:08 It would never happen because cloud computing would

10:11 always be that parent and edge computing would be a subsidiary

10:14 of it,

10:15 both would co-exist both will enable faster Cloud adoption

10:19 as a whole

10:20 So.

10:21 Yes friends

10:21 This brings us to the end of this video.

10:23 I hope you learned something new about Edge Computing.
