Top Five MicroFrameworks for JVM

We have heard about microservices and frameworks which are used to design microservices have you heard the term MicroFramework.in the last few years we have seen spring boot and vertex making the breakthrough with the creation of microservices using these frameworks.lets see what is microframeworks and why is it gaining popularity among the fast and robust applications.

Microframework as the name suggests is used to refer Small web application with limited set if libraries of features which are embedded inside the framework if you consider spring-boot ,spring boot is not a microframework because it has lot of additional features apart from what we need in order to make service run just like that however microframework is a term which is used to refer minimalistic web application framework and get you up to speed in order to develop web applications in order to full fill your functionality these frameworks are useful when you are creating API switch is specific to HTTP and when you are doing API specific mint or cloud-specific development then it is pretty useful because you can get these servers out very quickly 

Why are people moving towards MicroFramework Nowadays:-

It is due to the evaluation of the container based frameworks like docker and kubernetes if you want to create different docker images if you provide a spring boot application which already has tomcat and then you will have to create an image it provides lots of features for that particular small microservice however if you service is bound to only particular a set of domain or particular set of feature then you can go for microframework where you know what you have and you will be using what you need so that way you have a minimalistic application. for microservice architecture, it is necessary for an application to come up with very quickly if you take an example of spring boot it takes awhile to come up however vertex is faster than spring boot in order to make your system completely boot up within seconds. Microframeworks are ahead of the vertex as well it is much faster because if you need servals architecture like amazon lambda as a service provider by pivotal then you will have to make sure your application is much faster and they can respond within seconds so in order to go there microframeworks are required.
if let's say you are creating a service which is just going to provide a specific functionality and you don't have to keep that running always then you can create micro service with the help of microframework.

Functionality which lacks in Microframeworks:-

1)Database abstraction via an object-relational mapping.
2)Web template engine.
3)Accounts, authentication, authorization, roles, etc.
4)Input sanitation and input validation.
