Microservices is a popular architectural style for developing modern applications. Applications developed using this microservices architecture include small, independent services that interact with each other through well-defined APIs. This structural architecture offers many benefits, like reliability, scalability, agility, and resilience. However, this architecture also presents some challenges such as microservices isolation. Microservices architecture is responsible for handling their own data and state, making it difficult to ensure data and application integrity across the entire system.
In this blog post, we will discuss some microservices isolation patterns that can be used to ensure data and application integrity. We will also provide some examples of how these patterns can be used by US-based enterprises. Before that, let’s explore what microservices isolation is.
What is Microservices Isolation?
The process of separating microservices from each other to work independently that reduces their interdependencies and interactions, is known as microservices isolation. The network, application, and data levels can all be used for this.
Network-Level Isolation
There are several ways to achieve network-level isolation, including service meshes, firewalls, and load balancers. A service mesh is a specialized layer of infrastructure that offers fault tolerance, load balancing, and service discovery to manage microservices.
Application-Level Isolation
For application-level isolation, microservices are designed to work independently so that they avoid sharing their resources, such as databases and caches. In this level of isolation, each microservice should have its own dedicated resources.
Data-Level Isolation
Database-per-service architectures or distributed databases can be used to achieve data-level isolation. A database that is distributed among several nodes is known as a distributed database. While scalability and performance may increase as a result, data integrity may become more challenging to maintain.
Every microservice in a database-per-service pattern has its own dedicated database. This reduces complexity and costs while streamlining data management and facilitating data integrity assurance.
Microservices Isolation Patterns
The purpose of using microservices isolation patterns is to ensure data and application integrity. Here are a few examples of microservices isolation patterns:
- Circuit Breaker: One pattern that can be used in a microservices architecture to stop cascading failures is the circuit breaker pattern. A circuit breaker that trips will, for a while, stop all requests from going to a downstream service. This can reduce the chance of failure in one service that will create problems with other services.
- API Gateway: An API gateway is a single point where all requests to a microservices architecture can enter. Routing, authorization, and authentication can all be done via the API gateway. It can also be used to implement other microservices isolation patterns, such as circuit breakers and rate limiting.
- Database-Per-Service: The microservices in a database-per-service pattern have their own dedicated database. This reduces complexity and costs while streamlining data management and facilitating data integrity assurance.
- Event Sourcing: Event sourcing is a pattern, where every change or modification in the state is stored as a sequence of events. This can facilitate the tracking and auditing of state changes as well as the process of learning from mistakes.
- CQRS: CQRS (Command-Query Responsibility Segregation) is a microservices isolation pattern that uses different data models for writes and reads. Performance and scalability may increase as a result, and microservices isolation pattern implementation may become simpler.
Conclusion Building dependable and scalable microservices-based applications requires careful consideration of microservices isolation. US-based businesses can create microservices-based applications that can meet their demanding business needs by adhering to best practices and utilizing the isolation patterns covered in this blog post. Some US-based enterprises that use microservices isolation patterns are Netflix, Amazon, and Google.
