    This is a great video, the only thing I would have added is that microservices are most applicable when your teams, and the business, are structured in a way that needs separate development and release timelines. If that isn't the case, the disadvantages outweigh the advantages 9/10 times, as large services perform better, are easier to develop and secure, and cost less .

    What about when you move to serverless architectures where you pay for what you use and split your app into long running and short running functions? I ask because we’re doing a transformation and currently we deploy a monolithic app to a kubeneties cluster so we’re paying a constant fee to have resource’s running all the time, I would have thought moving this to lamda for all sub 10-15 minute tasks which is probably 80-90% of all tasks mean we pay fractions of a penny on an event and then any long running we move to step functions where we can or some docker container running on a smaller amount of fixed resources? Just wondering is all because I thought paying for fixed resources is more expensive than paying for time on resources?

    @@buddinghero That depends on if you actually can use fewer resources to run the remaining 10-20% of services. If you still need the same number of machines of the same size to run those 10-20% of remaining tasks, then it'd be largely a waste of time to separate out lambda functions, and you now also suffer performance additional deployment pipeline overheads for no/little gain. Monoliths are typically quite efficient for resource usage (RAM, CPU, network bandwidth etc.) as you don't have additional overheads of separate running operating systems/process domains. A big downside of Monoliths primarily being you have to deploy the whole unit every time stuff changes and depending on the language the compile time might be a significant overhead too.

    @@buddinghero If your services are used infrequently, serverless computing makes sense. But serverless is limited. Each cloud provider has their own serverless system so you are locked into a vendor. I normally use AWS. A request has to be processed within 5 seconds default timeout. It also has memory limit. To expose it to web, we have to use AppGateway, which is expensive and has its own way of deployment(dev/qa/prod). Sometimes I want service other than simple request/response like WebSocket, Cron, Subscription to MQ. Although AWS lambda sort of provide those functionality, I feels more natural to just set up a box. There are other obvious issues like cold start, no local state(no keep-alive, no internal cache, no connection pool), price(expensive when directly compared to ec2 or onprem server), deployment(need to deploy each function).

    Independent deployability of microservices is probably their biggest advantage because it leads large organizations to faster time-to-market while limiting the blast radius of new deployments. Besides, independent scalability of microservices over monoliths is a very crucial advantage which helps them adapt easily to the increasing workload.

    You can keep the foriegn keys, all you need to do is also have that table with only the information that it needs, this can be past from the source of truths service. E.g. if I create a new user, that source of truth service, will store the data and then publish a success message with the same data. This is so that another service can pick it up and store that same data, allowing the foriegn key. So if the users service goes down that other service still has that data, meaning it is fully functional.
