Lambda falls under “Compute” service in AWS . Lambda automatically runs our code without requiring us to provision or manage servers. We just need to write the code and upload it to the Lambda Function.
AWS Lambda Run code without thinking about servers or clusters.
Code can also be executed in response to events.
Although you might be used to writing statefully in these languages, you do have to remember that Lambdas are stateless. They just run your function once, then dispose of everything
You can write them in different languages, you can connect several AWS components together, and you only pay for what you use—all without managing any infrastructure.
EventBridge is a serverless event bus that lets you receive, filter, transform, route, and deliver events.
One of the Features of EventBridge that Beyon Solution utilize is “Scheduled events” Beyon Solutions will set up scheduled events using Unix cron syntax. Scheduled events are generated on a periodic basis and invoke any of the supported target AWS services.
Beyon Solutions was approached by Evexia Hospital to host their application in AWS. Evexia Hospital needed a cost-effective solution because it only has one IT administrator to manage both the UAT and production environments.
To meet the customer’s needs, the Beyon Solutions team set up a Lambda function and EventBridge AWS services. by defining two Lambda functions, one to start and one to stop the instance Then I created two Scheduled EventBridge rules, one for the start of the working hour and one for the end of the working hour, which will trigger the start and stop of Lambda functions.
Evexia Hospital’s business applications have been restarted in accordance with the configured scheduling feature, and they will save data.
Evexia Hospital’s business Applications were restarted as per the configured scheduling feature, and they will save up to 50% to 60% of charges in their monthly billing.
