Cloud Native Short Take - Microservices - Part 2

foreign [Music] welcome to part two of our short take on microservices in part one we talked about what a microservice is and how they're built how they couple in part two we'll talk about the pros and cons of using microservices to begin with it should be clear that building microservices is a much faster proposition than trying to build the entire application all at once we can deliver software and pieces of that software faster than we ever could since all we have to do is Implement one responsibility perhaps the best benefit of building with microservices is that we can scale our application to meet almost any demand any load by simply replicating the microservices in part one we talked about a payment microservice a microservice that would authorize a credit card charge well what if our application needs to process 2 000 cards in within five seconds the way we're going to do that is to replicate that microservice will spin up as many hundreds if not thousands as many as we need payment microservice containers to handle the load when the demand is no longer needed we can scale down so we adapt our scale to meet what's needed at the time we can incorporate new technologies by just replacing this one very small microservice without affecting the rest of the application we can align these microservices to the organization our payment microservice can be aided by the people that understand how payments are processed at our company we can respond faster to changes that Mastercard or VISA might demand of a stuff get a payment authorized and we have the opportunity to reuse these components in other applications however perhaps the the most important one for us with microservices is resiliency robustness of the application if you have 50 payment microservices running and one of them fails for whatever reason that's a small impact to the availability of the application it will likely go unnoticed and so the application stays up and running so although these are good benefits of microservices we should go into this with our eyes open they're now going to be a lot more containers a lot more processes to worry about to manage that's why we're forced to rely upon orchestration software such as kubernetes we understand that all of these microservices will need to interconnect our networking load and demands will be greater fortunately we live in a world where Network Technology and availability bandwidth is readily available in the cloud and in modern data centers so we can live with the increased Demand on networking and of course not every application is well designed for microservices this the more complex the application the more sense it makes to go to microservices but the opposite is also true so we hope you've enjoyed this short take on microservices hopefully you get to see what they are it's an architectural pattern to develop software they help us out with scalability and resiliency but we should go into this with our eyes open understanding that not every problem is well suited for an MSA architecture microservices is just one of many Cloud native and kubernetes modules from rxm visit rxm.com and select extensive course listing under the training menu to better understand the vast training options offered by our rxm team look for microservices part two on our YouTube channel where you can subscribe for more content from our exam thank you foreign
