Problem Statement :

A large Telecom enterprise wants to quickly revamp and modernize their existing legacy customer self-care application to boost customer satisfaction.

The self-care portal enables the end-users to retrieve and update basic information. Also provides them the capability to retrieve their itemized usage pdf statements.

Challenge :

The Telecom enterprise wants to adopt cloud architecture and leverage the benefits of the cloud while piloting on the self-care portal application use case.

Propose a cloud architecture for this use case.

Legacy Architecture :



Problem statement:

AWS free tier account bill was showing following charges : $0.01 per 1,000 metrics requested using GetMetricData API

I had created one cost budget in the mumbai region. While configuring the threshold for the budget, I had selected the “Forecasted Cost” option instead of actual cost. Seems selecting the forecasted cost option enabled the CloudWatch Anomaly Detection on the metrics. I could see 2 models under the CallCount metrics for the API resource “GetMetricData”. Anomaly detection was enabled for “sum” and “average” for the CallCount Metric

Action Taken:
Delete the models for both sum and average. Disable the anomaly detection for metric CallCount. Change the threshold for the created budget and configure it to use actual cost instead of forecasted cost for threshold.
