海外TECH	DEV Community	Let's Build Serverless Apps. Wait, Why?	https://dev.to/awscommunity-asean/lets-build-serverless-apps-wait-why-2f2i	Let x s Build Serverless Apps Wait Why This article is part of the AWS Community ASEAN content All presentations and ready to deploy codes used in this talk are available at AWS Community ASEAN Content Repo Beside containers serverless technology is something I consider an important part of modern application development While most people think of serverless as no server the definition I use to understand serverless is somewhat different Serverless is an operating model where we delegate various activities that do not provide value to our business to other parties By delegating these things we can focus on improving business logic and not worrying about infrastructure At the end serverless enables us to have less code less liability better integration better application more focus more values to deliver These are the real values for developers Looking back on some of the past speaking engagements I often get the opportunity to explain how we can build a particular solution using the AWS serverless services Recently I ve realized that I haven t done much at explaining the why or various logical reasons for using serverless And finally I decided to make this content Now that we ve set the context let s dive why using AWS serverless services might be a good approach for you Reason No Server ManagementThe main reason why using serverless gives you an advantage is that there is no server management This means that there is no need for patching retiring aging hardware and performing day to day operations or maintenance The most classic example is AWS Lambda AWS Lambda is a service where we can run a function without the need to manage hardware At minimum all we need to do is upload or write our business logic to AWS Lambda Like normal functions we can integrate with various databases or interact with HTTP API endpoints To trigger we can integrate with a variety of other AWS services ーsuch as HTTP API requests with Amazon API Gateway or when an object is uploaded into Amazon S For those who use containers you can also use AWS Fargate ーa serverless containers compute engine ーwhich you can use to run your apps Both of these options free you from provisioning to maintaingin your servers and you can allocate focus effort and time to what is more important building features for your application Reason Get to Market Fast and SecureOne of the misconceptions about serverless is that serverless is synonymous with AWS Lambda The fact is AWS Lambda is a subset of serverless If we refer to serverless as an operational model in practice serverless can be applied to any layer For example for computing we can use AWS Lambda and AWS Fargate For databases we can use Amazon DynamoDB as well as Amazon Aurora Serverless For integration from service to service we can use Amazon EventBridge and so on Another thing that is not less important is that each serverless service is rich in features that are difficult for us to replicate if we build it manually Take for example when you want to monetize your API You need to build a limit for different tiers for example a maximum of RPS with a limit of requests per day for plan A and RPS with a limit of requests per day for plan B You can use the usage plan feature that you can use directly within Amazon API Gateway The point is that by using the features of the serverless service you can get your apps to market faster But even though we can deliver our apps faster to the market we certainly need to think about security Before the era of cloud computing this was an option for me to deliver apps quickly or prioritize security which usually slows down apps delivery Now these two are not an option and we can do it at the same time The diagram below describes how we can maintain security of AWS Lambda to access Amazon CloudWatch and Amazon DynamoDB using the IAM Role Although this code runs fine if you don t have an IAM role to access DynamoDB it won t work This is one example where we can run applications more secure Reason Effective Scaling and Cost EfficientBefore the era of cloud computing to run services and apps I needed a fixed number of servers and of course this approach is not effective and cost efficient Cloud computing changed all of this by introducing auto scaling There are two types of scaling namely horizontal and vertical scaling scaling Horizontal scaling basically means adding a number of compute engines to your fleet Vertical scaling is more about adding power such as CPU or RAM to the existing machines in your pool With serverless the effort expended on handling requests is made easier by auto scaling Here I take an example of auto scaling for a database using Amazon DynamoDB Let s be straight here database workloads are difficult to predict and database scaling is a very challenging thing Most of the startups I used to be involved with were in the Media and Entertainment industry Read consumption for the database is higher between am pm and pm and handles approximately million requests during those hours Outside of those hours the requests are significantly reduced In other words the capacity of a database to handle requests is not the same as a high traffic hours Then I gave myself another thought on database When I switched from self managed MySQL to Amazon DynamoDB I benefited from auto scaling I can define the scaling configuration for read capacity and different configuration for write capacity The image below is an illustration of how auto scaling from Amazon DynamoDB works The red line is provisioned capacity and the blue line indicates actual consumption based on item size Here we can see that provisioned capacity adjusts the utilization rate to support application performance In addition this also reduces the cost that I need to pay because capacity is not fixed all the time and adjusts to requests Reason Flexible and Seamless IntegrationsServerless services on AWS are built with a specific purpose ーAmazon DynamoDB as database Amazon S as object storage Amazon EventBridge as event bus I d like to think them somewhat like a Lego building blocks This provides flexibility for developers to build architectures using appropriate services Due to its modular characteristics it makes it easier to build functionality for an application We can be more flexible on building applications from very simple to sophisticated architecture But if we are adopting various services that also means we also need to work on more integration That s right The more services that we use the more integration is needed Fortunately AWS serverless services have seamless integration which means we can integrate easily because the integration features are built in Take the example here on AWS Lambda you can easily do the integration by configuring them in the dashboard We can also find the same thing in other serverless services for example AWS Step Functions ーone of my favorite services because it can easily create visual workflows for distributed applications With AWS Step Functions we can define workflow flows and seamless integration with AWS Lambda by simply listing the ARNs from AWS Lambda Below is an example of how we can implement distributed transactions using state machine with AWS Step Functions using Amazon ECS and AWS Fargate Reason Faster Response with EventsAWS Lambda was first launched in late as an event driven function Triggering by event was something new and a bit unusual at the time but as we move our workloads into cloud the adoption of leveraging event increased Event itself is not something entirely new Events can take any form from changes in the state of a system ーsuch as when data is entered into a database ーto custom events ーsuch as in the context of e commerce when a customer places an order By leveraging events our applications can now respond to various kinds of events generated by the system or the services we have For example below is a near real time response by AWS Lambda to data changes that occur in Amazon DynamoDB This feature is called DynamoDB Streams where our system now has the ability to capture a time ordered sequence of item level modifications in any DynamoDB table Leveraging events is becoming more adopted in recent years and formally defined in Event driven architecture Event driven architecture is a paradigm in building architecture by using production and consumption to respond to an event Another example how serverless could help you is the implementation of choreography in microservices using Amazon EventBridge as a serverless event bus By using Amazon EventBridge we can easily define rules to route to which service we need to send data This gives us the advantage of decoupling between services so they can run their processes independently and scale according to requests Below is an example on how you can build choreography for microservices in context of e commerce application Wrapping up At this point you already understand some of the reasons to consider whether serverless can be your development system approach Serverless architecture can be used in almost all cases starting from building a simple serverless API IT automation streaming data processing to implementing microservices Although this requires a change in perspective from developing with a traditional approach but from my experience coupled with the development of features for AWS serverless services the serverless approach will provide significant advantages in the long run Happy building ーDonnieThis article is part of the AWS Community ASEAN content For those of you who want to learn more with presentations
