The Function-as-a-Service (FaaS) market is expected to soar past US$68.4 billion by 2030, fueled by cloud-native adoption, edge integration, and event-driven architectures. Explore key trends, growth segments, and top vendors in our latest global report.
Amazon AppSync Events now supports channel namespace data source connections, enabling developers to construct more complicated real-time apps. This new functionality links channel namespace handlers to AWS Lambda functions, DynamoDB tables, Aurora databases, and other data sources. AWS AppSync Events allows complex, real-time programs with data validation, event transformation, and persistent event storage.
Developers may now utilise AppSync_JS batch tools to store events in DynamoDB or use Lambda functions to create complicated event processing processes. Integration enables complex interaction processes and reduces operational overhead and development time. Without integration code, events may now be automatically saved in a database.
Start with data source integrations.
Use AWS Management Console to connect data sources. I’ll choose my Event API (or create one) in the console after browsing to AWS AppSync.
Direct DynamoDB event data persistence
Data sources can be integrated in several ways. The initial sample data source will be a DynamoDB table. DynamoDB needs a new table, thus create event-messages in the console. It just needs to build the table using the Partition Key id. It may choose Create table and accept default options before returning to AppSync in the console.
Return to the Event API setup in AppSync, choose Data Sources from the tabbed navigation panel, and click Create data source.
After identifying my data source, select Amazon DynamoDB from the drop-down. This shows DynamoDB configuration options.
After setting my data source, it may apply handler logic. A DynamoDB-persisted publish handler is shown here:
Use the Namespaces tabbed menu to add the handler code to a new default namespace. Clicking the default namespace’s setup information brings up the Event handler creation option.
Clicking Create event handlers opens a dialogue window for Amazon. Set Code and DynamoDB data sources to publish.
Save the handler to test console tool integration. It wrote two events to DynamoDB using default parameters.
The new data source connectors provide sophisticated error handling. You can return particular error messages for synchronous operations to Amazon CloudWatch to protect clients from viewing sensitive backend data. Lambda functions can offer specific validation logic for channel or message type access in authorisation circumstances.
AWS AppSync Events now provide data source integrations in all AWS regions. You may use these new features via the AWS AppSync GUI, CLI, or SDKs. Data source connectors only cost you for Lambda invocations, DynamoDB operations, and AppSync Events.
Real-time events
Create compelling user experiences
You may easily publish and subscribe to real-time data updates and events like live sports scores and statistics, group chat messages, price and inventory level changes, and location and schedule updates without setting up and maintaining WebSockets infrastructure.
Public/sub channels
Simplified Pub/sub
Developers can use AppSync Event APIs by naming them and defining their default authorisation mode and channel namespace(s). All done. After that, they can publish events to runtime-specified channels immediately.
Manage events
Edit and filter messages
Event handlers, which are optional, allow developers to run complex authorisation logic on publish or subscribe connection requests and change broadcast events.
Serverless computing is revolutionizing how developers build and deploy applications by eliminating the need for traditional infrastructure management. In a serverless environment, developers can focus solely on writing code while cloud providers handle the provisioning, scaling, and management of servers. This approach reduces operational overhead, improves agility, and allows developers to only pay for the computing resources they use, making it an efficient and cost-effective solution. Serverless computing services, such as AWS Lambda, Google Cloud Functions, and Azure Functions, automatically scale based on traffic, ensuring optimal performance without manual intervention.
This model is especially beneficial for microservices architectures, where different components of an application are deployed independently. Developers can build and deploy individual functions without worrying about managing the underlying servers, allowing for faster iteration and development cycles. Furthermore, serverless computing supports event-driven programming, making it an ideal choice for applications that respond to specific triggers, such as HTTP requests, database changes, or file uploads. This paradigm is quickly gaining traction across industries as it offers a flexible and scalable approach to application development.

Use CloudWatch Application Signals to monitor serverless application performance created using AWS Lambda.
An AWS built-in application performance monitoring (APM) solution called Amazon CloudWatch Application Signals was introduced in November 2023 to address the challenge of tracking the performance of distributed systems for apps running on Amazon EKS, Amazon ECS, and Amazon EC2. Application Signals expedites troubleshooting and minimizes application downtime by automatically correlating telemetry across metrics, traces, and logs. You may increase your productivity by concentrating on the apps that support your most important business operations using CloudWatch Application Signals‘ integrated experience for performance analysis within your applications.
In order to remove the hassles of manual setup and performance concerns associated with evaluating the health of applications for Lambda functions, AWS is announcing today that Application Signals for AWS Lambda is now available. You can now gather application golden metrics (the volume of requests coming in and going out, latency, problems, and errors) with CloudWatch Application Signals for Lambda.
By abstracting away the intricacy of the underlying infrastructure, AWS Lambda frees you from having to worry about server health and lets you concentrate on developing your application. This enables you to concentrate on keeping an eye on the functionality and health of your apps, which is essential to running them at optimal efficiency and accessibility. This necessitates having a thorough understanding of performance insights for your vital business processes and application programming interfaces (APIs), including transaction volume, latency spikes, availability dips, and mistakes.
In the past, determining the underlying cause of anomalies required a significant amount of time spent correlating disparate logs, KPIs, and traces across several tools, which increased mean time to recovery (MTTR) and operational expenses. Moreover, developing your own APM solutions using open source (OSS) libraries or custom code was laborious, complicated, costly to operate, and frequently led to longer cold start times and deployment issues when overseeing sizable fleets of Lambda functions. Without the need for manual instrumentation or code modifications from your application developers, you can now easily monitor and debug serverless application health and performance concerns with CloudWatch Application Signals.
By delving deeper into performance measurements for crucial business operations and APIs, you may quickly determine the underlying cause of performance abnormalities using CloudWatch Application Signals‘ pre-built, standardized dashboards. This aids in the visualization of the application topology, which displays how the function and its dependencies interact. To keep an eye on particular processes that are most important to you, you may also set Service Level Objectives (SLOs) on your applications. Setting a target that a webpage should render in 2000 ms 99.9 percent of the time over a rolling 28-day period is an example of a SLO.
CloudWatch Application Signals uses improved AWS Distro for OpenTelemetry (ADOT) modules to automatically instrument your Lambda function. You can swiftly monitor your apps with improved performance, including decreased cold start latency, memory usage, and function invocation duration.
Application Signals in the Lambda Console to gather different data on this application using an existing Lambda function called appsignals1.
You can enable the application signals and the Lambda service traces by choosing Monitoring and Operations Tools from the function’s Configuration tab.
This Lambda function is a resource that is attached to myAppSignalsApp, an application. For your application, you have established an SLO to track particular operations that are most important to you. Your objective is for the application to run within 10 ms 99.9 percent of the time within a rolling 1-day period.
After the function is called, it may take five to ten minutes for CloudWatch Application Signals to identify it. You will thus need to reload the Services page in order to view the service.
Now that you are on the Services page, you can see a list of every Lambda function that Application Signals has found for you. This is where any telemetry that is released will be seen.
Then, utilizing the newly gathered metrics of request volume, latency, faults, and failures, you can rapidly identify anomalies across your service’s various processes and dependencies and visualize the entire application topology from the Service Map. You can rapidly determine whether problems affecting end users are specific to a job or deployment by clicking into any point in time for any application metric graph to find connected traces and logs relating to that metric.
You can begin utilizing Amazon CloudWatch Application Signals for Lambda right now in any AWS Regions where both Lambda and Application Signals are accessible. Lambda functions that use Python and Node.js managed runtimes can now use Application Signals. Support for additional Lambda runtimes will be added soon.

Serverless Computing and Function as a Service (FaaS) are impressively acquiring traction in cloud-based application architectures. FaaS can be considered a subset of Serverless Computing. The developer only writes functions (usually small) that are pieces of code dedicated to executing a focused (usually single) task instead of coding an entire cloud-based application.
Although your application runs on servers in the serverless architecture, you’ll be free from the hassles of managing the infrastructure. The server management is completely managed by AWS or Amazon Web Services. Long gone are the days when you had to plan, measure, and manage the servers to run your applications, storage systems, and databases. Serverless enables you to swiftly adapt to emerging trends by helping you create more agile applications.
DataVizz is one of the best & reputed serverless app development companies in Ahmedabad, India. We offer a wide range of devops, aws lambda local development, and azure serverless web app at the best price.

The Union negotiates rights for major sports events and organizes their coverage for the region. It also runs prestigious annual Awards, TV Song and Radio Song Festivals.
Customer Challenge
The Customer drove their business through a SaaS based Application that did not offer them the flexibility to adapt to their requirements and the market. To overcome this business challenge, ABU decided to develop their own custom application. Developing a custom application to suite ever increasing business needs requires agility. In order to achieve the flexibility required, an agile development methodology was proposed by Aspire NXT.
Why AWS
As a new user of the platform, the customer was assured about the capabilities of Amazon Web Services. AWS provided the services for Developer tools with CICD to deploy the application in line with the vision laid out by the customer. A server less approach was chosen to deploy the application without VPC.
With immutable infrastructure, all changes were tracked in AWS Code Commit and software development methods like continuous integration and continuous deployment were implemented with AWS Code Pipeline and AWS Code Build.
To facilitate this in AWS, the customer chose to work with Aspire NXT, an IT services provider that is part of the AWS Partner Network (APN).
