I have developed my DRF back-end API locally, deployed it on an AWS Lightsail instance (with a public static IP) and I now want to secure it with HTTPS.
I understand that in order to use Let’s Encrypt (and not pay for an SSL certificate), I have to have a domain name associated to my instance IP since Let’s Encrypt doesn’t provide certificates for public IPs. As this is my back-end API (and not just a website), I don’t intend to buy a domain specifically for this.
Can I, somehow, associate my Lightsail IP with another domain that I’ve already purchased (and is used to host my company’s landing page)? If yes, will there be any impact on my API’s performance?
Is there any other alternative to obtain an SSL? (Apart from paying another CA to issue this for my public IP?)

I am working on a system that involves launching multiple AWS batch jobs, each takes between 5 to 15 minutes on average to complete.
I need to provide a mechanism that will let me know once all the jobs have completed successfully, or if any failures have occurred, so I can proceed to the next step accordingly.
Also, I don’t yet have a good strategy for handling errors. For example, how to deal with the case where only one or a few jobs failed after a certain number of retries? My first guess is that we can have a failure threshold that will dictate whether or not the overall step in the process (i.e. the collection of AWS batch jobs) can/should proceed. Something along the lines of
if failed_jobs > failed_job_threshold:
raise RuntimeError("Too many failed jobs")
The process recreates/repopulates a database table periodically (i.e. each month the overall job runs to recreate/repopulate a database table). Therefore any individual batch job failures will entail an incomplete database table and will require attention.
Is there a “best practice” architecture for handling this use case?
My development landscape includes Python, Terraform, Bitbucket Pipelines, AWS (Lambda, Batch, SQS, RDS/Aurora, etc.), and PostgreSQL.
