Amazon Web Services offers highly secure on-demand cloud computing services to people, governments, and businesses on a subscription basis. These services serve as the basis for the cloud deployment of any application. As a result, the top app developers opt for this when the question is about catering quality and efficient services.

The broad range of infrastructure services includes anything from networking, databases, and processing power to storage solutions. Through premium strategies and cloud migration, these services will allow you to experience greater growth in productivity and innovation.

Amazon Web Services (AWS) is the world's leading public cloud services provider, with over 100 AWS services encompassing 19 categories.

 Let's have a look at five important AWS services that would be ideal for your next mobile app development project.

1.AWS Lambda

The term "cloud computing" has recently become popular. It's not that servers don't exist; they do, but you no longer have to manage them. With AWS Lambda, you can run code based on the events without having to establish or manage servers. Simply upload the code, and Lambda will handle everything else, including scalability.

The user is not required to perform server administration. The code can be configured to be triggered automatically by other AWS services, or it can be called directly from any web or mobile app.

How it Works:

The code (called a "Lambda function") is then published to AWS Lambda. Each function contains the code as well as the configuration information for that function, such as the function name and resource needs. These functions can be configured to execute code in response to a variety of events.

Lambda functions are "unavailable" because there are no links in the underlying infrastructure. Scalability is made possible and simple by the ability to start an unlimited number of copies of the function. AWS Lambda executes code only when it is required and scales automatically based on demand.

It executes your code in a high availability compute environment and manages server and operating system servicing, capacity provisioning and automatic scaling, the release of code and security patches, and code monitoring and logging.

Key Features:

Add custom logic to other AWS services: AWS resources like Amazon S3 buckets and Amazon DynamoDB tables can also include custom logic. This amazing capability enables you to process compute data because it enters and leaves the cloud.

Build custom back-end services for apps: This feature makes it easier for you to make updates and modifications by allowing you to generate events for any kind of platform. As a result of the backend programmes being triggered on demand, battery consumption is also reduced.

No need to learn any new frameworks, tools, or languages: It can run programmes written in a variety of programming languages. The developer saves time by not having to learn any new programming languages or frameworks and by having the option to use third-party libraries.

Administration is completely automated: You can count on Lambda to complete any updates, patches, server additions, server sizing, or other tasks for you.

Built-in fault tolerance for reliable operational performance: Lambda provides built-in error detection to provide code protection across numerous machines, storage systems, and even individual center stages.

Automatic scaling based on incoming requests: Even during times of high demand and without sacrificing consistency or performance, Lambda automatically executes your code to scale and handle all incoming requests.

Integrated security model: AWS Lambda can be set up to access resources hidden behind a virtual private cloud. This enables you to take use of the benefits of both network access control lists and custom security groups.

Flexible resource allocation: gives you the flexibility to distribute resources according to your needs in terms of CPU power, network bandwidth, and disc I/O.

2.Amazon DynamoDB

You may store and retrieve any amount of data or traffic using Amazon DynamoDB, a fully managed NoSQL cloud database service, based on demand. When used at any scale, the database service offers consistent, single-digit millisecond latency.

Scalability is a key feature since it supports automatic partitioning, which allows any product requiring data, volume, expansion, etc. to function without any manual intervention. The service is a great option for gaming, web, ad tech, mobile, IoT apps, and a variety of other applications due to its advantages in terms of stability and scalability. Additionally, it has been specifically altered to accommodate various document kinds and key value store structures.

How it Works:

You can choose your preferred programming language before using DynamoDB because it supports Java, Javascript, Node.js, PHP, Python, Ruby, and NET. You can also set the target usage for auto scaling once the database table has been established.

You can set up the service to handle a variety of database management duties, such as setting up and configuring hardware or software, patching software, running a distributed database cluster, and dividing data across many instances for scalability.

Key Features:

DynamoDB Accelerator (DAX) in-memory cache: A completely controlled in-memory cache for DynamoDB, DynamoDB Accelerator (DAX), enables to cut processing time from milliseconds to microseconds. For time-consuming applications, this saves time because it multiplies performance by 10.

Global tables for a multi-region, multi-master database: It makes use of the fully managed, multi-region, and multi-master database to provide quick local read and write performance for international applications with significant scalability.

Full backups and restore: Regardless of the size of the tables, full backup of data in an Amazon DynamoDB table ensures that performance is not slowed down.

Secure encryption: The service ensures completely controlled encryption at rest using AWS KMS, or Key Management Service. When you wish to save and store sensitive data, it eliminates any operational difficulties and hassles.

Automatic, seamless scaling: This allows zero-downtime automatic throughput key structure in response to shifting needs. It examines actual traffic patterns and is ready to deal with a sudden increase in traffic.

Support for key-value data structures and documents: It offers assistance with searching and updating collections of items that are specified using specifications like keys and values to indicate where the real information is kept. Additionally, it enables the archiving, searching, and updating of records.

Amazon DynamoDB Console and APIs: You may develop, update, monitor, add, eliminate, and set alarms for tables with simplicity. Additionally, you can specify the duration for which certain table entries must be accessible before they expire.

Develop locally, scale globally: On your laptop or in the Amazon C2 Instance, it is simple to create and test applications locally. And when you're ready to scale, you can quickly upload it to the AWS Cloud using Amazon DynamoDB.

DynamoDB Streams to track changes: You can more easily capture and handle changes to DynamoDB data and tables thanks to DynamoDB Streams. You could track and address problems more rapidly if you did this.

Triggers: When changes are found in a table, AWS Lambda and DynamoDB can communicate to run a custom function.

3.AWS Device Farm

AWS Device Farm is a service for app testing. All types of apps can be tested on real mobile devices hosted by AWS. You can make advantage of the service in two ways:

• Remote Access - Interact with devices in real time from a web browser
• Automated Testing - Test the app concurrently against numerous physical devices in the AWS Cloud

With the help of the cloud app, you can test your iOS, Android, and web applications on actual mobile devices, making it appear as though actual users are using them with authentic movements, swiping, and interactions. You can access video, screenshots, logs, and performance data from your app so you know exactly what and where to solve it.

How Automated Testing Works:

You must first choose an app type—native, hybrid, or web app—in order to access the features of AWS Device Farm. The devices can then be directly accessed by developers through their local host computers to find bugs and performance issues.

How Remote Access works:

Your browser will display the chosen device when you choose it depending on the make, model, and OS version. The gadget can be used by the developer to simulate problems or test out new features.

Key Features:

Test accuracy: Using actual, physical equipment allows for extremely accurate testing. To test your Android, iOS, or Fire OS app on AWS-hosted devices, upload your own tests or built-in compatibility tests first.

Configure and simulate real world environment: Modifying the test scripts' parameters will promote dynamic settings. A variety of device configurations can be used to test programmes in real time on actual hardware to assess real-world client scenarios.

Development workflow integration: The service plugins and API included with Device Farm make it very easy to start tests automatically and access the results from IDEs and CI (Continuous Integration) environments.

Faster way to reproduce and fix bugs: You can manually introduce bugs while running automated tests in parallel, and then you can examine videos, logs, and performance data to figure out the exact location of the issues.

Secure testing: A number of cleanup procedures are available, including uninstalling the app after test completion. Additionally, the device will be taken away and unavailable. This ensures the security and safety of your software.

4.Amazon Cognito

A user-state synchronisation service called Amazon Cognito enables you to provide each of your users a distinct identity. In order to add user sign-up, sign-in, and access control for online and mobile apps, it offers secure app authentication.

How it Works:

It only takes a few lines of code to add the Amazon Cognito SDK to your application after establishing an AWS account. After implementing the Amazon Cognito management console, you can build a new Identity Pool and the Cognito credentials provider.

Your users' unique identifiers will be generated or obtained by the Cognito credentials provider, who will also set authentication tokens, the process for identifying and verifying identities, and the generation of a valid token when the user submits the required information.

Key Features:

Secure directory: A safe user directory with an amazing scalability of hundreds of millions of individuals is produced using Amazon Cognito User Pools. To verify each user, authentication tokens have been set up.

Social and enterprise identity providers: Users of apps can log in using Security Assertion Markup Language 2.0 and both social identity providers (such as Google, Facebook, Amazon, etc.) and enterprise identity providers like Microsoft Active Directory (SAML).

Built-in customisable UI: You may include user sign-up and sign-in pages in your applications with the help of the JavaScript, Android, and iOS SDKs for Amazon Cognito.

Standards based authentication: It makes advantage of widely used identity management technologies like SAML 2.0, OAuth 2.0, and OpenID Connect. This allows users to access your AWS resources with a temporary set of prohibited credentials.

Security and compliance: Even for applications demanding high-level security, you may meet a variety of security and compliance standards. It is HIPAA compliant and complies with ISO 9001, PCI DSS, SOC, ISO/IEC 27001, and ISO/EIC 27017.

5.Amazon Pinpoint

If you've been using targeted push notifications to increase mobile engagement, Amazon Pinpoint just makes it simpler to launch focused campaigns and track outcomes. Additionally, you can interact with your users by sending SMS, email, and push notifications to their mobile devices, such as:

• Campaigns to retain customers or send targeted messages for promotions
• Direct communications, such as mails confirming orders or password resets

How it Works:

You can collect consumer analytics information and develop customer segments with the AWS Mobile SDK Integration. Then, app users can receive customised multi-channel communications.

Key Features:

Track customer analytics:Integrate Amazon Pinpoint into your apps to track usage data, analyse user activity, and learn how users interact with and react to your messaging.

Global reach:Enjoy a reach of more than 200 countries and send messages using the user's preferred communication method.

Application analytics: Through AWS Mobile SDK, you can learn everything about how users interact with your app. For monitoring purposes, this data can be exported to external databases and applications.

A/B testing: There is an option for A/B testing to make sure messages are read by the intended audience.

Track campaign metrics: You can keep an eye on the messages that users receive and evaluate them to improve future campaigns. This would involve keeping track of the number of them who responded to the message, the number who ignored it, and the number who opted out.
