What is Typical Architecture Based on Microservices

Microservices require a lot of infrastructure, which is implemented by separate services. Load Balancers are used to load external HTTP requests from clients. Static content is delivered via a content delivery network. The business requirements services are supported by a variety of platform or infrastructure services. These take over central tasks such as application and service monitoring, logging web services, operations databases, configuration management, encryption, authorization and authentication, as well as auto scaling, software distribution, A/B testing and fault injection testing (FIT). In addition, there are central routing services , which deal with the assignment of URLs to instances with the respective services. In addition there are services for data persistence, in particular caching, relational databases and NoSQL databases, as well as BLOB storage for arbitrary files.

Both SOA (service-oriented architecture) and microservices use services as architectural elements. SOA uses services to integrate different applications. The combination of services is orchestrated or choreographed , and portals can provide a common user interface (UI) for all services. Microservices structure an application through services. Each microservice can contain a user interface and implement business processes as found in SOA in the orchestration.

Microservices is a bunch of focused and small services which, on execution develops a complete application. A single responsibility of the application which we are developing is represented by an instance of a microservice.

The product or software which might have taken a year to deliver can now be delivered in weeks with the help of Micro Service Architecture. SOA uses Enterprise Service Buses which is comparatively a slower with respect to messaging mechanism used in Microservice Architecture, SOA consists outsized RDBMS whereas Microservice Architecture use micro-SQL. Microservices has more differences with SOA.

Presently, Microservice Architecture becoming more precise and smaller architecture which introduce many benefits enough to make the business more scalable. Also, testing and maintenance across various independent teams become possible.

 

Typical Architecture Based on Microservices

 

A typical and well-managed architecture based on Microservices should display the following attributes :

• Decoupling of Databases
• Increased Flexibility for Programmers
• Specific API endpoints
• Correlated calls with the help of various methods like IDs, tokens or headers
• Optimized fault tolerance and consistent performance monitoring with the effective use of caching to help speed up the response time
• More integrated Devops
• Security more robust and unbiased
• Standardized development practices along teams

 

How we can achieve data consistency in a microservice architecture? Each database model should be 100% decoupled from another. Achieving data consistency can be very challenging. We should plan ahead on how to handle the failure scenarios in the future in-order to acquire data consistency in an early design stage.
