Can embedded tomcat or any such embedded server be used for microservices in production environment? How, embedded server is different wrt the normal standalone full fledged server (performance . reliability wise)? Is the embedded server light weight compared to standalone? What are the features that embeded servers do not have compared to their standalone ones? Can we change the default security settings, tls ciphers etc advanced things in embedded tomcat?

Embedded Tomcat offers a way to package Java web applications that is consistent with a microservices-based approach to software development. It also makes it easier to distribute Java web applications through Docker containers and manage them through a container orchestration service, such as Kubernetes or OpenShift.
Embedded tomcat means in runtime inside your JVM Spring boot starts a server with the dependencies in your jar. So all the problems of pushing the war to tomcat folder and restarting are eliminated. Build your jar using Spring boot plugin.
xml, i.e. set the value of packaging element as war as such: <packaging>war</packaging> . But this is manifestly an extra step. Deploy the project in Production as a running Java program with the embedded Tomcat, meaning there is no normal Tomcat Server at all in production.
For example, for a Spring Boot Application, you can generate an application jar which contains Embedded Tomcat. You can run a web application as a normal Java application! Embedded server implies that our deployable unit contains the binaries for the server (example, tomcat.
Does each microservice need its own server running (Tomcat, docker container)? No, it is quite possible to run all of your microservices on a single server or even on a single docker container.
Embedded tomcat server with a spring boot and server, which have an alternative to your base on building a simpler, ci pipeline integrated automatically. by default, the auto-configurer sets up your project with .
You need to identify what compels you to go for external tomcat deployment. As SpringBoot provides out of box facility to deploy within the container, it is not required to go for external tomcat deployment. Besides, if you are going for many microservices, it will be good to have with built in springboot with embeded tomcat.
Besides, if you are going for many microservices, it will be good to have with built in springboot with embeded tomcat. Springboot also provides the facility to use undertow or jetty.
Well, it's a matter of choice. I've seen some services which use embedded tomcat in production and some services which rely on standalone tomcat container which is directly provided by the platform. Some platforms might not have a java runtime, in such scenarios you're bound to use embedded containers for tomcat or jetty. The key difference would be that standalone containers can host multiple java deployments whereas for single deployments you can stick to the embedded ones. And yeah reliability and performance won't be a huge concern, although I believe that standalone containers are designed to be more scalable. From my personal experience, embedded deployments are easier to manage, since we can custom configure the tomcat setting specific to that deployment (might be the answer to your last question)
