Microservices Building Blocks
Microservices or miscroservices architecture, is a concept under which applications are built up of loosely coupled components. It’s a trend that is growingly being adopted by many organizations and especially large enterprises, to benefit from lots of advantages related to agility, scalability, availability, maintainability and more.
You may look at microservices, as small building blocks of an application. With microservices, a single functionality can be broken down into several services, each is deployed and re-deployed independently from other services. Each microservice, implements a functionality or a business capability, that can be developed by different teams and may run on different databases. This is unlike Monolithic applications, which run on the same database/s and are deployed and managed as one.
Going for Microservices?
With microservices, it becomes easier and faster for developers to implement new services and understand and maintain existing services. In addition, developers would be able to choose their development language that best fits the service, they could also easily use new technologies with less dependence on a single technology stack. Moreover, adaptability and re-usability are enhanced and thus time to market is improved.
Building Microservices Capabilities
With the independence nature of microservices, changes have less impact on the whole applications, and thus testing effort is reduced, issues numbers are reduced and technical debt is reduced, hence higher efficiency, higher costumer experience and less code maintenance costs.
With the acquired flexibility of independent deployment, the scalability of services could be easily attained, the availability of services could be enhanced and application resilience guaranteed. Look at an example for a telecom company that is launching a new attractive campaign, it would be very challenging to maintain the availability of their whole application, because if the campaign relevant services are over using the shared memory, the whole application could be impacted and become unavailable. With microservices, only the campaign services would be impacted, and then it could also remain available, because a single microservice could be deployed as multiple instances on multiple servers based on demand. The nature of microservices paves the way for smoother agile software development and DevOps.
