Back to work for you, back to school for your kids, September is coming and I'm also back to business! I have great news to start this newsletter: Our second event will occur on September 24 and I'm pleased to have Quentin Rosso (CTO at Gamercraft) to speak about how they use serverless to build their gaming platform. It will be online, registration is open. I'm also working on the 3rd event which should occur by the end of October... stay tuned! Another good news, at least for me, is my first article published on the AWS Blog. More info below... And as usual, some great content to read... Enjoy! Jerome

| Containers have peaked – brace yourself for the serverless takeover |
|
Not sure if containers have peaked already, but what is sure is more and more companies want to avoid dealing with undifferentiated things such as managing infrastructure and shift their focus to dev and business value. And serverless definitely helps with this. If the cloud is young, serverless is even more. Cloud adoption is quickly growing now, let's give a few months/years to serverless to become a standard. |

Scheduling AWS Lambda Provisioned Concurrency for recurring peak usage |
|
|
I'm really happy to have my first article published on the AWS Blog. If you use Provisioned Concurrency with your Lambda functions, in order to reduce latency due to 'cold starts', you may want to schedule it when you know you have traffic (early in the morning or before recurring peaks). In this article, I describe how to do this with Application Auto Scaling, a not so well-known service (not to confuse with EC2 Auto Scaling). |
| Choreography vs Orchestration in the land of serverless | |
|
As always, really good article from Yann Cui on two modes of interaction when dealing with microservices. Choreography leverages SNS or EventBridge to notify loosely coupled services. And Orchestration leverages Step Functions to build a workflow and orchestrate different services. Both can be combined to provide efficient microservice architectures. |
| Building storage-first serverless applications with HTTP APIs service integrations |
|
AWS announced the native integration of HTTP API with 5 services (including SQS, EventBridge and Step Functions). This means that you no longer need VTL templates to call those services directly from API Gateway. It also opens the door to the 'storage-first' pattern: first store (and secure) your data in a Queue or a Stream and then process it. It provides better resilience while simplifying the development, really cool! |
| Serverless-Flow: A CI/CD Branching Workflow Optimized for Speed and Quality | |
|
I've been using the git flow for quite a long time and was happy with it. Then the github flow came and simplify it. Now, Ben Ellerby exploits in addition to serverless capabilities (ephemeral and pay-per-use) to build its CI/CD: strong quality in a shorter time. |
| How to Fan-Out to Different SQS Queues Using SNS Message Filtering | |
|
Fan-out is a really common pattern when working with serverless and that's why I wanted to list this post here. In the article, Lorenz Vanthillo describes how to implement it using SNS and SQS and applying filter policies with SNS to route messages to the desired queues. It's worth knowing it... |
