Benefits of Micro services

 Benefits of Micro services

 

Micro services architecture

  • The micro service architecture style is an approach to developing one application as suite of small service.
  • Each runs in its own process and communicates with light weight mechanisms, often on HTTP resource API.
  • Micro service do have distinct advantage:
Better Organization

  • Micro service architecture are typically better organized
  • Each micro service features a really specific job, and it isn't concerned with the roles of other components.
Decoupled
  • Decoupled services are also easier to vary , update and re-configure to serve the requirements of varied type apps
  • They also leave fast, independent delivery of individual parts within a much bigger , integrated system.

Performance

  • Under the right circumstances, micro services can also have performance advantage relying on how they're organized.
  • It's possible to isolate hot services and scale them independently of the rest of the app.

Micro services-oriented

  • Cloud native applications are built as a system of micro services. the overall idea of this style of architecture is to implement a system of multiple, relatively small applications. These are called micro services.
  • They work together to supply the general functionality of your system.Each micro services realizes;
  • Exactly one functionality
  • Have a well defined boundary and API( Application programming interface-used for communication).
  • Gets developed and operated by a comparatively small team

Benefits of micro services

  • During a micro services architecture, services are fine-grained and thus the protocols are lightweight.
  • Services are organized around business capabilities.
  • Services are small in size, messaging-enabled, bounded by contexts, autonomously developed, independently deploy able.
  • This makes the appliance easier to understand , develop, test, and become more resilient to architecture erosion tons easier to implement and understand a smaller application that provides one functionality, instead of building an out sized application that does everything.
  • That accelerates development and makes it tons easier to adopt the service to changed or new requirements.
  • Since micro services are implemented and deployed independently of each other, i.e. they run within independent processes, they're going to be monitored and scaled independently.
  • You would wish to stress tons less about unexpected side effects of a seemingly chickenfeed , and you will specialize in the event task at hand.
  • It also allows you to scale more efficiently.
  • And albeit you merely use a little a neighborhood of the monolith, you still need to acquire additional resources for the other , unused parts but during a cloud environment, you purchase the usage of hardware resources.

Challenges Using Micro Services

  • There is saying: There's no such thing as a Free Lunch.Micro services remove some complexity from the services themselves and provide better scalability, but you're now building a distributed system.
  • That adds a lot more complexity on the system level.
  • To make sure that dependent services find each other and communicate efficiently its a challenging task when number of micro-services are many.
  • We also need to handle slow or unavailable services so that they don't effect the complete system.
  • The distributed nature of our system also makes it a lot harder to monitor and manage our system in production.
  • Instead of a few monoliths, we now need to monitor a system of micro services and for each service , there might be several instances that run in parallel.

What is Internet of Things (IoT)?

 What is Internet of Things (IoT)?    The internet of Things, or IoT, refers to the billions of physical devices  round the  world that are now connected to  the web  , collecting, sharing and analyses  of knowledge  . It presents and provides the explanation of the network of physical things which is embedded with software , sensors,  and other technologies for the benefit of connecting and exchanging data with other devices and systems on the internet   . Due to the cheap processors and wireless networks, it's possible to  means  anything, from a pill to an aero plane to a self-driving car into  an area  of the IoT. Overview IoT will control the Fourth  technological revolution  . The Fourth  technological revolution  is changing the very software-defined automation allows manufacturers to link all stages of  the worth  chain, rapidly adapt to changing markets , and make highly personalized products on a mass scale. The opportunities provided by this revolution are authenticated

What is Rust Borrowing?

What is Rust Borrowing? Borrowing We call having references as function parameters borrowing. As in real world , if an individual owns something, we 'll borrow it from them . Whenever we’re done, we 've got to offer it back. Referencing  The reference is that the act of consulting somebody or something so as to urge information We would  declare reference in terms of Rust programing as if we are taking a replica of it without damaging or taking its ownership. ‘&’ symbol is employed to pass the reference Have a look that  how ‘&’ symbol is employed in code. fn main() { let s1 = String::from("hello"); let len = calculate_length(&s1); println!("The length of {} is {}.", s1, len); } fn calculate_length(s: &String) -> usize { s.len()} Mutable References The actual concept of mutable reference is same as we use mutable variable When  we  need to  modify  mutable reference is employed once   the worth we make regard to.

Kubernetes Readiness Probes

 Kubernetes Readiness Probes Description We understand that liveness probes and the way they assist keep our apps healthy by ensuring unhealthy containers are restarted automatically. Same like liveness probes, Kubernetes permit us to also define a readiness looked for our pod. The readiness probe is deployed periodically and examines whether the precise pod should receive client requests or not. Whenever a container’s readiness probe returns back success, it’s signaling that the container is ready to simply accept requests. This notion of being prepared is clearly something that’s specific to every container. Almost as liveness probe Kubernetes sends requests to container and supported the result either successful or unsuccessful response it decides container is prepared to require traffic or still preparing for that. The liveness probes not like, if a container fails the readiness check, it won’t be killed or restarted.   This is a very good practice to
