Besides what others commented about concurrent reqs in EC2 vs independent lambda execution costs, the trick considering all that is that Lambda is more efficient in terms of costs than EC2 UP UNTIL a certain amount of reqs/s, from that threshold onwards, the appropriate EC2 instance is cheaper.

If you have a somewhat low utilization application, it’s not even close: Lambda is dramatically cheaper. I’ll illustrate that below with two simple examples to give you a sense of what “low utilization” means. Maximize Your AWS Investment with Trek10's 24/7 Monitoring

AWS Lambda Pricing
4 days ago - The table below contains a few examples of the price per 1 ms associated with different memory sizes, for usage falling within the first pricing tier – for example, up to 6 billion GB-seconds / month in US East (Ohio) ... Lambda on-demand duration pricing tiers are applied to aggregate monthly duration of your functions running on the same architecture (x86 or Arm, respectively), in the same region, within the account. If you’re using consolidated billing in AWS Organizations, pricing tiers are applied to the aggregate monthly duration of your functions running on the same architecture, in the same region, across the accounts in the organization.

How much does AWS Lambda cost?
AWS Lambda uses a pay-as-you-use model and the cost entirely depends on your usage. The calculation is based on usage ($/invocation) and duration of computing ($/hour). Every month you get 1 million invocations and 3.2M seconds of compute time for free. After that it will cost $0.0000002 per invocation and about $0.0000166667 for every Gb/s of compute time.

r/aws on Reddit: Why is everyone saying Lambda is more expensive than EC2?
May 23, 2023 -
Please help me work out the math here, as I think I am doing this wrong.
A Lambda of 128mb costs $0.0000000021/ms, this works out $0.00756/hour. A Lambda of 512mb costs $0.0000000083/ms, this works out $0.02988/hour.
Now if you look at EC2:
t4g.nano $0.0042/hour (0.5 GiB ram) t4g.micro $0.0084/hour (1GiB ram).
But... the Lambda will likely not run 100% of the time, and will stay warm for 10 minutes (not sure here?). And the RAM usage would be much better utilized if you got a function running, rather than an entire VPC.
Given all that, if the function can run with 128mb or less, it seems like a no-brainer to use Lambda.
However, if the function is bigger, it would only make sense to put it in an EC2 if it runs more than 30% of the time ($0.0084/hour cost of t4g.micro divided by 0.02988/h cost of 512mb lambda).
So why is everyone against Lambdas citing costs as the primary reason...?

For EC2 you can run more than 1 request at the same time. For lambda it is 1 lambda per request. If you have even a few concurrent requests you lambda cost can 5-10x noting all the cold start and other times too.

If you expect to not have traffic 24x7 and low concurrent usage then Lambda may end up working out to be cheaper. Lambda is extremely expensive for my company because we have hundreds or thousands of concurrent executions.
