• Nanoservice is an antipattern where a service is too fine-grained.
  • It is designed to do only one action at a time and expose it as a single API endpoint. Each command in nanoservices is likely to be distinct, whereas microservices may include several commands. 
  • The key difference between the two technologies is that they are smaller siblings of microservices. 
  • Each one can connect to other services to do additional activities and enhance functionality.

Nanoservices: Key themes 

  • Self-contained 
  • Extra-small that consists of a piece of code 
  • Reusable
  • Antipattern 
  • Microservices are easier to use.

Why Nanoservice? 

  • The initial setup is simple. 
  • Reduced service latency, as each nanoservice’s function code may run on-demand without the need for dedicated containers or servers to host each service 
  • They’re more granular than microservices and have a faster feedback loop, allowing you to detect and fix issues quicker.

Real-world use of Nanoservices 

The Discovery+ website is a real-world example of nanoservices in action, including nanoservices rendering dynamic web pages, generating headlines, retrieving meteorological data, and updating newly added show results, among other things.

The section of the page produced by the nanoservice is shown by a Green outline

Furthermore, another nano service combined them to create a Red outline across the top of the page. 

Advantages of Nanoservice 

  • A nanoservice can have its own security protocol 
  • As compared to microservices, they are more concentrated and lightweight. 
  • Multiple teams can work on a single service or numerous services. 
  • Flexibility to use different services 
  • It is possible for each service to have its own security protocol. 
  • It can be independently designed, tested, and deployed. 
  • Easy to deploy 
  • Linking multiple services together to increase functionality has been made easier. 

Current challenges of Nanoservices 

It has challenges, namely in the areas of control and understanding. How do you keep track of what should be occurring when numerous developers are constructing nanoservices that are then linked in numerous ways? 

  • Duplicate services need more effort to create and maintain. 
  • Building and maintaining a highly efficient infrastructure is difficult and expensive. 
  • Due to the large number of services you’re supporting, you’ll use more resources. 
  • Complex error-tracking may come from tighter service-level interdependence. 

 Microservices Vs Nanoservices 

  • Because nanoservices are smaller than microservices, more individuals can work on the process in which they are involved at the same time.  
  • Because nanoservices are utilised in so many ways, they must be versioned. However, maintaining them all on the same version is unfeasible, and keeping track of version proliferation is difficult. Semantic versioning is available in Node.js, which is useful but does not support a proper upgrading policy. 
  • To be more specific, a nanoservice can be built and provided on its own timetable by the developer. When a microservice gets too concentrated, it is renamed a nanoservice. 
  • Nanoservices differ from microservices in that they are smaller, more isolated, and more concentrated in comparison to microservices. This means you won’t have to worry about frequent releases having a negative impact because there will be fewer things to break. 

Concluding Words :

  • Nanoservices are a relatively recent concept. If there are multiple things running on the website, like the Discovery+, nanoservices are always a superior alternative. 
  •  Furthermore, nanoservices will improve the speed of the website by reducing load time, allowing you to provide better user experiences.
