1 00:00:00,480 --> 00:00:06,900 In this section we will walk through with a management console for a lambda. 2 00:00:07,530 --> 00:00:11,670 We will create, configure, invoke and test our lambda functions. 3 00:00:12,060 --> 00:00:19,080 But before that, I would like to show you to begin page of a lambda in the management console. 4 00:00:19,110 --> 00:00:25,380 In the begin page we will understand how Lambda works with the following the step by step tutorial of 5 00:00:25,380 --> 00:00:26,520 the Lambda. 6 00:00:27,060 --> 00:00:28,440 Let's get started. 7 00:00:28,830 --> 00:00:36,660 Please open the ADA signing page and log in the console with the IAM user, which we create in the last 8 00:00:36,660 --> 00:00:37,290 section. 9 00:00:39,220 --> 00:00:45,190 So this will be open the dashboard section of our management console. 10 00:00:45,760 --> 00:00:53,560 And if we go to the lambda section, you can search by Lambda and you can add the favorites by clicking 11 00:00:53,560 --> 00:00:54,540 the start button. 12 00:00:54,550 --> 00:00:58,300 The Lambda function, by this way, you can see lambda in here. 13 00:00:58,300 --> 00:01:05,290 So now let's click the lambda button and go to Lambda Dashboard section. 14 00:01:05,890 --> 00:01:12,250 So this is the dashboard screen of the lambda and it is opening the Discover page. 15 00:01:12,250 --> 00:01:19,630 As you can see the URL, you can see the Discover in here, but there is also a hidden begin page that 16 00:01:19,630 --> 00:01:22,330 explains Lambda Executions very well. 17 00:01:22,330 --> 00:01:29,980 So please change the urine and remove the discover and right to begin. 18 00:01:30,610 --> 00:01:38,710 I'm going to remove this cover and right begin hit the enter and see that we are open begin page that 19 00:01:38,710 --> 00:01:40,990 explains a lambda very well. 20 00:01:40,990 --> 00:01:43,570 You will see the welcome message of the lambda. 21 00:01:43,750 --> 00:01:47,800 This is the beginning page and it includes several widgets. 22 00:01:47,800 --> 00:01:55,300 You can scroll down and see that there are some widgets like how it works and related services, more 23 00:01:55,300 --> 00:01:59,260 resources, use cases, pricing and costs and so on. 24 00:01:59,530 --> 00:02:05,380 So if you scroll up, you can see that this is the old picture of the lambda. 25 00:02:05,380 --> 00:02:07,900 Let's overview from the beginning of the page. 26 00:02:07,930 --> 00:02:10,480 There is a definition about a lambda. 27 00:02:10,660 --> 00:02:11,590 It is lambda. 28 00:02:11,590 --> 00:02:15,040 Lets you run the code without thinking about servers. 29 00:02:15,160 --> 00:02:18,760 You pay only for the complete time that you consume. 30 00:02:18,760 --> 00:02:24,130 There is no charge when your code is not running with lambda, you can run the code for virtually any 31 00:02:24,130 --> 00:02:28,240 type of the application or backend services, all with zero administrators. 32 00:02:28,480 --> 00:02:31,000 So how Lambda is works. 33 00:02:31,000 --> 00:02:34,480 If you scroll down here, you can find a step by step visit. 34 00:02:34,510 --> 00:02:41,170 This is a visit in this page and this is the step by step wizard that explain how Lambda works. 35 00:02:41,170 --> 00:02:41,950 Very well. 36 00:02:41,980 --> 00:02:44,500 Let's start with the first step here. 37 00:02:44,500 --> 00:02:50,260 You can find the different languages and runtimes that can be run on the lambda. 38 00:02:50,290 --> 00:02:55,600 This is the net go java, node.js, python, ruby and Custom Runtime. 39 00:02:55,690 --> 00:03:02,080 We will follow the Node.js default runtime is selected Node.js and you can see simple lambda function 40 00:03:02,080 --> 00:03:02,500 code. 41 00:03:02,530 --> 00:03:07,870 This is the very basic lambda function code that basically logs the incoming event and turn back the 42 00:03:07,870 --> 00:03:09,280 helo from Lambda Message. 43 00:03:10,260 --> 00:03:14,220 Basically it is locking incoming emancipation object and turning back the halo message. 44 00:03:14,250 --> 00:03:20,310 We can detect the run lambda function code in this window, so if we click the run button, this will 45 00:03:20,310 --> 00:03:25,710 directly run this lambda function and see that is the response of the lambda function. 46 00:03:25,710 --> 00:03:31,410 Hello from message a the this lambda function successfully worked and return back to hello message. 47 00:03:31,650 --> 00:03:40,290 So if you proceed the visit you can see that there is the next button will be activated next lambda 48 00:03:40,290 --> 00:03:42,510 response to events button is activated. 49 00:03:42,540 --> 00:03:45,720 Please click this button and see what's happened. 50 00:03:45,990 --> 00:03:53,130 So in here we can find the animation about how to scale automatically and manage lambda executions with 51 00:03:53,130 --> 00:03:56,700 creating and distributing lambda execution environments. 52 00:03:56,700 --> 00:04:01,620 This is a very good illustration that you can understand lambda function scaling features. 53 00:04:01,620 --> 00:04:08,790 Also, we can see how in locations and cost affected one thing from the different services to Lambda 54 00:04:08,790 --> 00:04:09,600 executions. 55 00:04:09,600 --> 00:04:15,600 So basically in this animation we can send different events from different event sources to the lambda 56 00:04:15,600 --> 00:04:21,970 function until we go to Lambda Invocations and see that how lambda execution environment created and 57 00:04:21,970 --> 00:04:22,940 this structured. 58 00:04:23,100 --> 00:04:30,210 So you can see that we can send an event for a mobile notification, we think in location. 59 00:04:30,420 --> 00:04:36,060 For example, when you click this button you can see that we are triggering an invocation of the lambda 60 00:04:36,060 --> 00:04:42,720 function and this is the encoding, increasing the concurrent executions and writing the logs in here. 61 00:04:42,750 --> 00:04:49,200 So this is very good illustration so we can send the event a mobile notification with synchronous invocation 62 00:04:49,200 --> 00:04:55,350 or streaming data to lambda function which trigger with the event source mapping invocations like from 63 00:04:55,350 --> 00:05:04,050 Kinesis or dynamic DB streams, the streaming or placing a photo in the S3 bucket with a synchronous 64 00:05:04,050 --> 00:05:04,620 invocation. 65 00:05:04,620 --> 00:05:05,730 The Lambda function. 66 00:05:05,850 --> 00:05:12,240 And this is very good illustration from different type of applications or services invoking the lambda 67 00:05:12,240 --> 00:05:16,680 functions with different invocation types, synchronous, asynchronous or streaming. 68 00:05:16,680 --> 00:05:22,800 So let me click icons and please see that how lambda execution environment creates and log the console 69 00:05:22,800 --> 00:05:26,100 after finished the function environment will be destroyed automatically. 70 00:05:26,280 --> 00:05:30,990 I'm going to click these buttons and see that. 71 00:05:32,410 --> 00:05:37,930 You can see that these execution environments are increasing and when the function finished, these 72 00:05:37,930 --> 00:05:39,880 are destroying automatically. 73 00:05:40,000 --> 00:05:46,810 This is very good illustration that you can see very well how the location increased by automatically 74 00:05:46,810 --> 00:05:54,070 from a place and how this destroyed automatically from the scaling up and scaling down. 75 00:05:54,250 --> 00:05:57,700 So this is the power of the servers competing with a lambda. 76 00:05:57,730 --> 00:06:03,100 It is totally auto scaling and handle incoming events with different loads automatically scale with 77 00:06:03,100 --> 00:06:05,550 creating lambda execution environments. 78 00:06:05,560 --> 00:06:10,510 So if you click the next button, which is the step by step visit. 79 00:06:10,540 --> 00:06:13,330 Click next scale seamlessly. 80 00:06:13,870 --> 00:06:19,030 So I'm going to click this button and this time we will see how to scale seamlessly. 81 00:06:19,060 --> 00:06:25,690 Lambda Scale up and down automatically to handle our workloads and we don't pay anything when our code 82 00:06:25,690 --> 00:06:26,590 isn't running. 83 00:06:26,770 --> 00:06:35,020 So the first 1 million requests or 4000 gigabyte seconds of compute per month are free because in this 84 00:06:35,020 --> 00:06:41,110 demo are based on the 128 megabyte function with a one second invocation duration. 85 00:06:41,110 --> 00:06:44,230 So this is really powerful features of a lambda. 86 00:06:44,260 --> 00:06:51,190 See that again, I'm going to send different request invocations from other resources and this will 87 00:06:51,190 --> 00:06:59,020 be calculated in locations and potential cost in here of course are very low because when we are clicking 88 00:06:59,020 --> 00:07:04,480 one button in here, one in location, this will be sending 1 million requests. 89 00:07:04,480 --> 00:07:07,870 So that's why this is very a great feature. 90 00:07:07,930 --> 00:07:13,390 And see that even in location count is two millions or five millions. 91 00:07:13,390 --> 00:07:17,050 Cost is less than $0.05 almost. 92 00:07:17,080 --> 00:07:25,330 Okay, let's continue to our step by step visit and create our function and see what's happened. 93 00:07:25,360 --> 00:07:29,980 So yes, when we click the create function, you can see the create function page. 94 00:07:29,980 --> 00:07:33,070 Now we are ready to create our lambda function.
