AWS App Runner dashboard

Introduction to AWS App Runner

Deploying web applications in the cloud can be complicated, especially for teams that don’t have a lot of experience with cloud infrastructure. AWS App Runner helps with this by offering a fully managed service that lets you deploy web applications and APIs directly from your source code or a container image. In this article, we’ll look at how AWS App Runner makes deployment easier and discuss its main features.  

What is AWS App Runner?

AWS App Runner is an AWS service that provides a fast, simple, and cost-effective way to deploy from source code or a container image directly to a scalable and secure web application in the AWS Cloud. You don’t need to learn new technologies, decide which compute service to use, or know how to provision and configure AWS resources.

AWS App Runner connects directly to your code or image repository. It provides an automatic integration and delivery pipeline with fully managed operations, high performance, scalability, and security.

AWS App Runner dashboard

AWS App Runner supports two main deployment methods:

  1. Source-based deployment: Directly from your source code.

  1. Cost-Effectiveness
    With pay-as-you-go pricing, App Runner charges you based only on the resources your application uses.
  1. Enhanced Security
    App Runner integrates with other AWS services like AWS Identity and Access Management (IAM) to enforce security policies. Plus, applications deployed via App Runner are automatically encrypted, adding an extra layer of data protection.

Pricing for App Runner

App Runner provides a cost-effective way to run your application. You only pay for resources that your App Runner service consumes. Your service scales down to fewer compute instances when request traffic is lower. You have control over scalability settings: the lowest and highest number of provisioned instances, and the highest load an instance handles.

Who is App Runner for?

If you’re a developer, you can use App Runner to simplify the process of deploying a new version of your code or image repository.

For operations teams, App Runner enables automatic deployments each time a commit is pushed to the code repository or a new container image version is pushed to the image repository.

Boost DynamoDB Performance with DynamoDB Accelerator (DAX): A Complete Guide

DAX architecture

Boost DynamoDB Performance with DynamoDB Accelerator (DAX): A Complete Guide

DAX architecture

Amazon DynamoDB is a strong, fully managed NoSQL database that can grow quickly and adapt easily. But when dealing with high-traffic applications or high latency workloads, even the best databases can improve with caching. This is where DynamoDB Accelerator (DAX) helps.

In this blog post, we’ll look at how DynamoDB Accelerator (DAX ) works, its advantages, and how to use it to make DynamoDB work better.

What is DynamoDB Accelerator (DAX)?

DynamoDB Accelerator (DAX) is an in-memory cache for DynamoDB that accelerates the read performance of your tables. As an external caching layer, DAX can reduce the time it takes to retrieve frequently accessed data by caching it in memory. Unlike traditional caching layers, which require setup and maintenance, DAX is fully managed by AWS and integrates seamlessly with DynamoDB.

With DAX, applications can achieve up to a 10x reduction in read latency especially for read-heavy and repeated read workloads.

How to Set Up and Configure DAX

DAX sits between your application and DynamoDB tables, functioning as an in-memory cache for read requests. When your application queries data, DAX first checks if the requested data is available in the cache:

  • If the data is present in DAX, it’s returned directly from memory, achieving microsecond latency.
  • If the data is not in DAX, it queries DynamoDB, retrieves the result, and then caches it in DAX for future requests.

Amazon DynamoDB Accelerator (DAX) is designed to run within an Amazon Virtual Private Cloud (Amazon VPC) environment.

To run your application, you launch an Amazon EC2 instance into your Amazon VPC. You then deploy your application (with the DAX client) on the EC2 instance.

DynamoDB workflows

Key Features of DynamoDB Accelerator (DAX)

Fully Managed and Highly Available: DAX is fully managed by AWS, meaning you won’t have to worry about infrastructure management, setup, or maintenance.

In-Memory Caching for Microsecond Latency: As an in-memory cache for DynamoDB, DAX stores recently accessed data in memory, significantly improving data retrieval speeds.

Seamless Integration with DynamoDB APIs: One of DAX’s standout features is that it seamlessly integrates with existing DynamoDB APIs, meaning it doesn’t require changes to application logic.

Configurable Cache TTL (Time to Live): DAX uses a default TTL of five minutes, which means cached data will automatically expire after five minutes to ensure consistency with DynamoDB. However, TTL can be adjusted to meet application needs, allowing you to balance cache freshness and retrieval speed.

Benefits of Using DynamoDB Accelerator (DAX)

  1. Reduced Read Latency: DAX provides single-digit millisecond response times by reducing the number of direct queries to DynamoDB.
  2. Cost Efficiency: By caching frequently read items, DAX reduces the number of read operations hitting DynamoDB directly, helping reduce costs on read-heavy workloads.
  3. Scalability: DAX is designed to scale automatically with your DynamoDB usage patterns. It can handle sudden spikes in traffic by distributing cache data across multiple nodes.
  4. Fully Managed Service: AWS takes care of the setup, patching, and maintenance of DAX clusters, allowing developers to focus on application logic.
  5. Ease of Integration: DAX works seamlessly with DynamoDB and requires only minor adjustments to existing code to take advantage of its performance improvements.
Use Cases for DynamoDB Accelerator (DAX)

DAX is ideal for read-heavy workloads where latency is critical and immediate consistency is not required. Some popular use cases include:

  • E-commerce Catalogs: DAX allows product catalogs to load faster, especially during high-traffic events like Black Friday, where many users are browsing at once.
  • Gaming Leaderboards: Leaderboards require fast access to score data, and DAX’s caching can handle high read volumes effectively.
  • Social Media Applications: Social feeds involve numerous reads of user content, which DAX can accelerate significantly.
  • Session Stores: User session data, which is read frequently but not often updated, can benefit greatly from DAX caching.
Pricing and Cost Considerations

DAX is priced based on the hourly usage of nodes in your cluster, and additional charges apply for data transfer. While there is an upfront cost for using DAX, the reduction in DynamoDB read requests can lead to significant savings over time, particularly for read-intensive applications.

DynamoDB Accelerator (DAX) vs. Amazon ElastiCache

While DAX serves as an in-memory cache for individual DynamoDB items, Amazon ElastiCache is a more general-purpose caching solution, suitable for caching complex, aggregated data from multiple sources. Here’s a quick comparison

Diagram illustrating DynamoDB Accelerator (DAX) performance benefits

Conclusion

DynamoDB Accelerator (DAX) is a powerful tool for reducing read latency, optimizing costs, and delivering seamless performance for read-heavy applications. By leveraging in-memory caching, DAX offers a way to handle high-traffic workloads without sacrificing speed or scalability.

AWS Resource Access Manager

AWS Resource Access Manager (RAM) Explained: Securely Share Resources Across AWS Accounts

Introduction

Amazon Web Services (AWS) provides Resource Access Manager (RAM), a powerful service that enables you to share AWS resources with other AWS accounts. In multi-account AWS environments, RAM simplifies resource sharing, making it easier to manage permissions while maintaining security. AWS RAM provides a flexible solution for sharing resources like Amazon VPC subnets, Route 53 Resolver rules, and more.

What is AWS Resource Access Manager?

AWS Resource Access Manager (RAM) is a service that allows users to share AWS resources across different accounts. By using RAM, organizations can achieve seamless collaboration between teams and departments while maintaining a high level of security and control over the resources being shared. RAM works particularly well in environments using AWS Organizations, where multiple accounts are centrally managed under one structure.

AWS Resource Groups

Create groups for your AWS resources. Then, you can use and manage each group as a unit instead of having to reference every resource individually. Your groups can consist of resources that are part of the same AWS CloudFormation stack, or that are tagged with the same tags. Some resource types also support applying a configuration to a resource group to affect all relevant resources in that group.

Resource share

You share resources using AWS RAM by creating a resource share. A resource share has the following three elements:

  • A list of one or more AWS resources to be shared.
  • A list of one or more principals to whom access to the resources is granted.
  • A managed permission for each type of resource that you include in the share. Each managed permission applies to all resources of that type in that resource share.

Sharing account

The sharing account contains the resource that is shared and the AWS RAM administrator creates the AWS resource share by using AWS RAM.

Consuming principals

The consuming account is the AWS account to which a resource is shared. The resource share can specify an entire account as the principal,

Some of the resources you can share using AWS RAM include:

  • Amazon Virtual Private Cloud (VPC) subnets
  • AWS Transit Gateway
  • Amazon Route 53 Resolver rules
  • AWS License Manager configurations

Benefits of Using AWS RAM

Simplified Multi-Account Management: RAM enables easy management of shared resources across accounts within an AWS Organization, reducing the complexity of managing separate resources for each account.

Enhanced Security: Resource sharing with RAM allows you to control which resources are accessible to specific accounts, ensuring a secure environment.

Cost-Efficiency: By sharing resources like VPC subnets and Transit Gateways, you can avoid redundant resources, minimizing costs.

Scalability: RAM is built to scale, allowing organizations to manage and share resources as they grow.

Managing and Monitoring Resource Shares

Once your resources are shared, AWS RAM provides several options for ongoing management and monitoring.

  • View Active Shares: From the RAM dashboard, you can view all active shares, including details of resources, permissions, and principals.
  • Modify Resource Shares: RAM allows you to modify existing shares if you need to add or remove resources, change permissions, or update target accounts.
  • Audit Resource Sharing: Use AWS CloudTrail to log RAM activities for security auditing and compliance, ensuring you can track resource-sharing actions over time.

Pricing

AWS RAM is offered at no additional charge. There are no setup fees or upfront commitments.

Best Practices for Using AWS RAM

  1. Use AWS Organizations: If managing multiple accounts, use AWS Organizations to streamline resource sharing with OUs and individual accounts.
  2. Follow the Principle of Least Privilege: Only grant permissions necessary for resource usage to minimize security risks.
  3. Enable CloudTrail for Monitoring: Enable CloudTrail to monitor and audit resource-sharing actions for compliance and security.
  4. Review Permissions Regularly: Periodically review RAM permissions and update them to reflect current usage and security requirements.

Conclusion

AWS Resource Access Manager (RAM) provides an effective and secure way to manage resource sharing across AWS accounts, helping organizations streamline their operations, reduce costs, and maintain robust security controls. AWS RAM is a valuable tool for any organization leveraging a multi-account setup, offering flexibility, security, and efficiency as you manage your cloud resources.
