Introduction

In this blog, we will learn about AWS serverless Application repository. We will also learn how we can publish the applications and deploy them. Developers and companies can quickly identify, deploy, and publish serverless applications in the AWS Cloud using the AWS Serverless Application Repository. The AWS Serverless Application Repository and the AWS Lambda console are tightly connected. Because of this integration, developers of various skill levels can get started with serverless computing without learning anything new. You can search for apps such as web and mobile backends, data processing programs, and chatbots using category keywords. 

Publishing Applications 

Following are the steps required to publish the application:

1. Initialize: Using sam init, download a sample application from the template.

2. Test Locally: Test on a small scale. Use sam local invokes or sam local start-API to test the application locally. Even though your Lambda function is executed locally with these commands, it reads from and writes to AWS resources in the AWS Cloud.

3. Package: Use the sam package command to bundle the Lambda function, AWS SAM template, and any dependencies into an AWS CloudFormation deployment package after you're pleased with it. At this point, you'll also provide details about the app that was submitted to the AWS Serverless Application Repository.

4. Publish: Using sam publish, publish the application to the AWS Serverless Application Repository. After completing this step, you may now view your application in AWS Serverless Application. AWS Serverless Application Repository stores the repository and deploys it to the AWS Cloud.

Deploying Applications 

You can search for publicly available applications without needing an AWS account by accessing the public portal. Alternatively, you can use the AWS Lambda console to search for applications.

The AWS console, the SAM command-line interface, and the AWS software development kits all provide access to the Serverless Application Repository. You must have all components specified and packaged using SAM templates before publishing an application to the AWS Serverless Application Repository.

Before deploying applications from the AWS Serverless Application Repository, understand application deployment rights and capabilities.

Application Deployment Permissions

You must have the authority to deploy an AWS Serverless Application Repository application. You have the control to deploy the following three types of applications:

1. Private - Apps made with the same account and haven't been shared with anybody else. You can deploy applications developed with your AWS account.

2. Privately Shared: Applications that have been specifically shared with a specific set of AWS accounts by the publisher. You can use your AWS account to deploy applications that have been shared with you.

3. Publicly shared - Applications that the publisher has made available to the general public. 

Any publicly shared application can be deployed with your authorization. Only applications for which you have permissions can be searched and browsed. These include applications produced with your AWS account, applications shared privately with your AWS account, and applications shared publicly with your AWS account.

Deleting Application Stacks

Follow the same steps as uninstalling an AWS CloudFormation stack to delete an application you previously deployed using the AWS Serverless Application Repository:

 

1. AWS Management Console -  

Follow the following steps:

1. Go to AWS CloudFormation console to access it.

2. Select the stack you want to delete from the Stacks page in the CloudFormation console. The stack must be active right now.

3. Select Delete from the stack information pane. When prompted, choose Delete stack.

2. AWS CLI -

The aws cloudformation delete-stack command is used to delete a stack. The name of the stack you want to delete must be specified. When you delete a stack, you're removing it together with all of its resources.

For example to delete ‘mystack’ the following command should be used:

aws cloudformation delete-stack --stack-name mystack

 

Now let us see how security is ensured by AWS Serverless Application Repository.

Security in the AWS Serverless Application Repository 

At AWS, cloud security is a principal focus. You have access to a data center and network architecture designed to fulfill the needs of the most security-conscious businesses.

Cloud security 

AWS takes charge to safeguard the infrastructure that runs AWS services in the AWS Cloud. AWS also offers services that you can utilize securely. As part of the AWS compliance initiatives, third-party auditors test and verify the effectiveness of our security.

Cloud-based security 

The AWS service that you utilize determines your obligation. Other examples, such as the sensitivity of your data, your company's requirements, and applicable laws and regulations, are also your responsibility.

Data Protection 

Data protection in AWS Serverless Application Repository follows the AWS shared responsibility paradigm. AWS protects the worldwide infrastructure that supports the entire AWS Cloud. You are in charge of keeping your material hosted on this infrastructure under your control. The security configuration and administration activities for the AWS services you use are covered in Data Protection.

Encryption in Transit

Endpoints of the AWS Serverless Application Repository API only support secure HTTPS connections. When you use the AWS Management Console, AWS SDK, or the AWS Serverless Application Repository API to manage AWS Serverless Application Repository resources, all communication is protected with Transport Layer Security (TLS).

Encryption at Rest 

The encryption procedure converts data using an algorithm that renders the original data unreadable. The AWS Serverless Application Repository encrypts all files you upload, including deployment packages and layer archives.

Identity and Access Management 

It allows administrators to manage access to AWS services securely. Authentication (signing in) and authorization (having permissions) to use AWS Serverless Application Repository resources are controlled by IAM administrators. 

Managing Access Using Policies

A policy is an AWS object that defines the permissions of identity or resource. Log in as the root user, an IAM user, or as an IAM role. AWS examines the applicable identity-based or resource-based policies when you make a request. The policy permissions decide whether the request is approved or rejected. The majority of policies are saved as JSON documents on AWS.

API Permissions: Actions and Resources Reference 

Create policies and associate them with IAM accounts or AWS resources to control access in AWS. The permissions of that identity or resource are defined. Log in as the root user, an IAM user, or a role in the IAM system. AWS examines the associated identity-based or resource-based policies when you submit a request. The request is approved or rejected based on the policies' permissions. JSON documents are used to store most policies in AWS.

Logging and Monitoring 

Monitoring is a crucial component of ensuring your AWS solution's stability, availability, and performance. If a multipoint failure occurs, you should collect monitoring data from all aspects of your AWS solution to more readily diagnose it. AWS provides numerous tools for monitoring and responding to potential problems in your AWS Serverless Application Repository resources.AWS CloudTrail, a service that provides a record of actions made by a user, role, or AWS service in the AWS Serverless Application Repository, is connected with the AWS Serverless Application Repository. All API requests for the AWS Serverless Application Repository are captured as events by CloudTrail.

Logging AWS Serverless Application Repository API Calls with AWS CloudTrail 

AWS CloudTrail, a service that provides a record of actions made by a user, role, or AWS service in the AWS Serverless Application Repository, is connected with it. All API requests are captured as events by CloudTrail. Calls from the AWS Serverless Application Repository console and code calls to the AWS Serverless Application Repository API activities are among the calls collected.

You can allow continuous delivery of CloudTrail events to an Amazon S3 bucket if you establish a trail, which includes events for the AWS Serverless Application Repository. You can access the most recent events in the CloudTrail console's event history.

Compliance Validation  

As part of numerous AWS compliance programs, third-party auditors assess the security and compliance of the AWS Serverless Application Repository. SOC, PCI, FedRAMP, and others are among them. The sensitivity of your data, your company's compliance objectives, and applicable laws and regulations determine your compliance obligation while utilizing the AWS Serverless Application Repository.

Resilience

AWS Regions and Availability Zones form the foundation of the company's global infrastructure. Multiple physically separated and isolated Availability Zones are joined by low-latency, high-throughput, and highly redundant networking in AWS Regions. Availability Zones are more highly available, fault-tolerant, and scalable than traditional single or multiple data center infrastructures.

Infrastructure Security  

The AWS Serverless Application Repository is safeguarded as a managed service by the AWS global network security processes. To access the AWS Serverless Application Repository over the network, you use AWS published API calls. Clients must support transport Layer Security (TLS) 1.0 or later. Clients must also implement cipher suites that provide perfect forward secrecy (PFS). These modes are supported by most current systems, including Java 7 and beyond.
