In this issue, we are looking into S3 Files and paired with AWS Lambda, ECS (Fargate), and EKS. It effectively turns S3 into a low-latency, “warm” file system for serverless compute without the need for manual data staging.

For serverless, S3 Files turns your "cold" data lake into a "hot" local drive, eliminating the code complexity of managing local caches and data synchronization.

“/tmp pattern” in AWS Lambda involves a three-step dance: downloading an object from S3 to the local ephemeral storage, processing it, and uploading it back. While functional, this introduces latency (cold starts), adds code complexity, and is limited by the 10 GB /tmp ceiling. Amazon S3 Files fundamentally changes this by replacing the Data Transfer phase with a Mount phase and using the file system to easily access files.

⭐ Pick of the month

This month’s Pick is “SQS + Lambda”.

Rehan van der Merwe breaks down the 7 SQS Lambda EMS Scaling behaviors from Lambda invocations and how cold start depends on batch sizes and ESM poller invoking the Lambda.

Jones Zachariah Noel’s (author) has published how to get started with SQS and understanding types of SQS: Standard and FIFO. If you have cross-account messages, the SQS queue can trigger cross-account Lambda. Also, if you are internested with SQS monitoring and the metrics to look at to understand SQS performance.

It’s valenties day, and the love for Serverless is 1MB max payload across Lambda, SQS, and now even Amazon EventBridge.

For developers, this means the days of “claim-check” patterns—where you’d store a large payload in S3 and just pass a pointer in the event—are over for many common use cases. You can now ingest much richer data directly into your Event Bus, from dense LLM prompts and complex Generative AI outputs to high-frequency telemetry signals and massive JSON blobs. By removing the need to split, compress, or externalize your data, your architecture becomes significantly leaner. With EventBridge, SQS, and Lambda all speaking the same “1 MB language,” you can pass these large payloads through your entire serverless pipeline without worrying about a 256 KB bottleneck at the router.

The “new normal” eliminates the architectural overhead of the “claim-check” pattern, allowing you to pass rich 1 MB payloads—like LLM prompts or dense telemetry—directly through a unified EventBridge, SQS, and Lambda pipeline. By removing the need to externalize large data to S3 or chunk it into smaller pieces, you achieve a leaner, faster architecture

AWS has launched Fault Injection Service (FIS) support for DynamoDB Global Tables with Multi-Region Strong Consistency (MRSC). This allows you to intentionally inject faults into your global replication to see if your app stays standing. This update moves resilience from a theoretical “five-nines” (99.999%) promise to a verifiable reality by allowing you to simulate regional replication pauses in a controlled environment. Instead of waiting for an actual AWS outage to see how your stack behaves, you can now proactively trigger failure scenarios to observe how your application handles replication lag, validate that your New Relic dashboards or CloudWatch alarms actually fire during a crisis, and ensure your Lambda retry logic gracefully manages the disruption. By intentionally breaking the sync between regions, you can fine-tune your recovery time objectives (RTO) and confirm that your “strongly consistent” application doesn’t accidentally serve stale data or crash when the network gets messy.

In this issue, we are taking a closer look at durable functions with the shift away from ASLs.

Orchestration = Step Functions until the launch of durable functions, where the state machine was purely Amazon States Language (ASL), making it IaC friendly but not programming language-friendly for the developers. Durable functions bring in a workflow as code approach, reducing cognitive overhead without the hassles of defining heavy ASL based state machines; it’s all code defined with the SDK.

I asked Gemini to give me a one-liner analogy with ASL v/s Durable functions -

ASL is like building a model with LEGO bricks: you have specific pieces that fit together in specific ways. Durable Functions is like 3D printing: you have the raw material (code) and can create any shape or logic you can imagine.

In this issue, we are looking at AWS Lambda Managed Instances, which were rolled out as part of the pre:Invent.

AWS has just bridged the gap between Serverless simplicity and EC2 flexibility. The new AWS Lambda Managed Instances capability allows you to run Lambda functions on dedicated Amazon EC2 capacity—without the headache of managing the underlying infrastructure. As simple as it sounds,

• Create a Capacity Provider: Define your VPC, subnets, and preferred EC2 instance types.

• Attach Functions: Link your Lambda functions to the Capacity Provider via ARN.

• Scale Automatically: AWS monitors traffic and spins up new EC2 capacity in seconds when needed.

This new capability is specifically designed for steady-state workloads, offering up to 72% cost savings through EC2 Reserved Instances and Savings Plans. By introducing a multiconcurrency model, a single execution environment can now handle multiple simultaneous requests, which—combined with pre-provisioned capacity that eliminates cold starts—significantly improves resource efficiency and latency without requiring changes to your core Lambda programming model.

AWS Lambda Durable Functions are capable of building reliable, long-running, multi-step applications and AI workflows without needing to manage complex external orchestration or state.

• Reliable Multi-Step Workflows: Enables you to define complex processes (like order processing, user onboarding, or multi-step AI tasks) directly within the Lambda function code.

• Automatic Checkpointing & Recovery: The function’s progress is automatically saved (checkpointed). If the function fails or is interrupted, it can automatically resume from the last known checkpoint, strengthening application resilience.

• Long-Running Execution: Functions can suspend execution and wait for up to one year for long-running tasks or external events (like human approval or an API callback).

• No Compute Charges for Waiting: When the function is paused (waits), you do not incur compute charges, making long-running workflows highly cost-efficient.

• Simplified Development: You use familiar programming language constructs and new operations like “steps” and “waits” via an open-source SDK, eliminating the need to write custom state management or integrate with additional infrastructure.

• Built-in Error Handling: It provides automatic retries and recovery from failures.

AWS Lambda announced a powerful new Tenant Isolation Mode that completely transforms how you build secure, multi-tenant SaaS applications.

If you run multi-tenant applications on Lambda (think workflow automation or code execution platforms), achieving strict tenant isolation was often a manual headache involving complex custom routing or even deploying a dedicated function for every single tenant.

Why SaaS Teams are Cheering:

• Stop Building Custom Solutions: Ditch the complexity of managing per-tenant routing logic or siloed function deployments.

• Ironclad Isolation: Instantly meet strict security and compliance requirements by ensuring compute resources are isolated per tenant.

• Focus on Features: Spend less time on operational complexity and more time building your core product.

That’s a powerful feature change for event-driven architectures! The increase in the asynchronous invocation payload limit from 256 KB to 1 MB fundamentally simplifies how you handle rich, contextual data in serverless workflows. While the pricing for the payload up to 256kb still remains the same per request, the payload with 256kb to 1mb would be on a model of 64kb additional request chunk, which now means you’ll be paying for the exceeding payload on a consumption basis.

What does it mean for architectures? Your Lambda triggers - EventBridge, Step Functions, S3, Kinesis Data Streams, or even another Lambda function can now send more data in the innovation, making it more efficient than the Lambda Function reading them from a data store.

In this issue, we look at the messaging and integration services on AWS - EventBridge, SQS, SNS, MSK, which help with stitching the complete “event-driven-architectures” with Event Buses, Queues, Topics or Streams that are all purposed for sending messages/events from the producer to subscribers. These services also help with decoupling and ensuring the messages/events are routed to the right subscribers. Speaking about routing, filter patterns are very crucial; now with Customer Managed Key support to rule filter patterns and input transformers on EventBridge.

If you are still worried, when do I use SQS or SNS? This blog post should help you understand it better.

AWS has introduced two key features to enhance serverless development and multi-tenant system resilience. For AWS Lambda, the new console-to-IDE integration and remote debugging capabilities streamline development by allowing developers to seamlessly transition from the AWS console to VS Code for editing and to debug live Lambda functions directly in the cloud. This improves the development workflow and helps identify issues earlier. Simultaneously, Amazon SQS Fair Queues have been launched to address the "noisy neighbor" problem in multi-tenant architectures. By dynamically prioritizing messages from "quiet" tenants when an imbalance is detected, Fair Queues ensure consistent message dwell times for all tenants without compromising overall queue throughput, thus building more resilient systems.

⭐ Pick of the month

This month’s Pick is “SQS + SNS“.

Jones Zachariah Noel N (Author) shares why observability matters for Event-Driven Architectures, bringing in challenges of EDA with AWS services and how metrics, specifically from SQS and SNS with New Relic integrations, help.
If you are confused about when to use SQS or SNS, the blog should help to understand it better, maybe a combination of it!

Amazon DynamoDB previewed Multi-Region Strong Consistency (MRSC) at AWS re:Invent 2024. And now, this is generally available (GA).

DynamoDB provides you with a global table capability, which creates replicas across regions and the common challenge was ensuring the replicas are consistent (or in sync across all replicas). With MSRC, you can now write to DynamoDB with the multi-region-consistency STRONG attribute, ensuring that the replicas are consistent.

Donnie Prakoso shares more on this front in the blog - Build the highest resilience apps with multi-Region strong consistency in Amazon DynamoDB global tables
