Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 41 discussion

This question just screams AppFlow (SaaS integration) https://aws.amazon.com/appflow/

It says "LEAST operational overhead" (ie do it in a way it's the less work for me). If you know a little Amazon AppFlow (see the some videos) you'll see you'll need time to configure and test it, and at the end cope with the errors during the extraction and load the info to the target. The customer in the example ALREADY has some EC2 that do the work, the only problem is the performance, that WILL be improved scaling out and adding a queue (SNS) to decouple the work of notify the user. The operational load of doing this is LESS that configuring AppFlow.

B. Cree un flujo de Amazon AppFlow para transferir datos entre cada fuente de SaaS y el depósito de S3. Configure una notificación de eventos de S3 para enviar eventos a un tema de Amazon Simple Notification Service (Amazon SNS) cuando se complete la carga al depósito de S3. Explicación: Amazon AppFlow permite la integración directa con múltiples fuentes de SaaS y automatiza el flujo de datos hacia Amazon S3, eliminando la necesidad de instancias de EC2 para recibir y cargar datos. Esto reduce la carga en las instancias de EC2 y simplifica el proceso de integración y recolección de datos. Notificación de eventos de S3 y SNS : Configurar eventos en Amazon S3 permite enviar notificaciones directamente a un tema de Amazon SNS cuando los datos se han cargado, lo cual asegura que los usuarios recibirán notificaciones sin necesidad de código personalizado en EC2.

B for sure

direct connect maybe correct answer but we are making too many assumptions regarding direct connect network requirements.

Has to be appflow because of the SaaS integration

First i thought it would be A but with more stydy found if its Saas and need to choose between EC2 and aws managed service one should always choose AWS managed service. So AppFlow seems more appropriate here.

Amazon AppFlow is a fully managed integration service that helps you securely transfer data between software as a service (SaaS) applications such as Salesforce, SAP, Google Analytics, Facebook Ads, and ServiceNow, and AWS services such as Amazon Simple Storage Service (S3) and Amazon Redshift in just a few clicks. https://aws.amazon.com/appflow/

https://aws.amazon.com/appflow/ "With Amazon AppFlow automate bi-directional data flows between SaaS applications and AWS services in just a few clicks." If you want to pass the exam, choose B, regardless of your personal experience! Always use AWS managed services for "least operational overhead"

SaaS - AppFlow

Yea , I think this question is looking for Amazon Appflow.I also feel like it would be easier to set up Autoscaling for the already existing EC2 instances in the short term but then the fact that this software integrates with a lot of SAAS services means using Amazon Appflow will work reduce operational overhead in the long term

B suits the requirement

The problem with A is you need to add ALB or ELB in front of ASG, and update DNS for your application, so B seems like a better choice.

This is a tough one. If they were not already using EC2 the answer would for sure be AppFlow (B). The question says "least operational overheard" so I feel like it takes more work to configure AppFlow than it does to create auto scaling in EC2. If I had this question on the test, I would likely go with AppFlow so B

While option B utilizes managed services and can be a valid approach, it's important to note that Amazon AppFlow is primarily designed for data integration and synchronization between various SaaS applications and AWS services. It may introduce an additional layer of complexity compared to directly handling the uploads with EC2 instances. Ultimately, the choice between Option A and Option B depends on specific factors such as the existing architecture, the nature of data transfers, and any potential advantages offered by using Amazon AppFlow for data integration. If the primary concern is to improve performance for data uploads and user notifications without introducing new services, Option A (Auto Scaling group with S3 event notifications) would likely be the simpler and more operationally efficient choice. However, if data integration between SaaS sources and the S3 bucket is a critical aspect of the application, Option B might be a more suitable approach.
