You may have heard the term Microservices when talking about applications, and some cases even when talking about underlying infrastructure. If you’ve worked with any OOPS language, you must be familiar with the concept of abstraction and modularization. Extend that idea to an application – the breakdown of independent functions abstracted in to separate services; with a bunch of services working together forming an application. Typically, the more fine grained and decoupled your services are, the more scalability can be achieved.
Let’s take a look at some of the reasons why it is important for your critical applications to be be implemented with a microservices architecture framework –
Scalability: By splitting down the function of an application in to a microservices, it can be scaled independently of other functions or components. For example, a microservice responsible for managing database connections can scale independently of the web tier, if the db connection pool size is to be increased.
Decoupling: Separating the functions into individual services provides flexibility for design, implementation, and maintenance of those individual services.
Continuous Delivery & Updates: Functional upgrades can be released without affecting other components. Each function or service can have its own release pipeline, list of enhancements, and priority for feature releases.
Error Micro-segmentation: Error in one service will be isolated within that service. Faults will not propagate to other functions as they are modularized and separated. Also, releasing an update to address the issue is quicker and more efficient in this architecture.
Parallel Development & Domain Expertise: Each service can have domain specific experts working on it. In the case of monolithic applications, the entire application stack needs to be updated for feature releases, as well as development is stymied because of complexity and interdependencies.
Reduced Deployment Time: Individual services can be deployed with a focus on function specific features and environments. Development, testing, and pipeline release is for smaller modules rather than the entire application stack. Frequent updates can be made to individual services, and those updates can be deployed in production much faster.
If you need assistance in determining the feasibility of transforming your applications from monolithic to microservices architecture, Keyva can help. Associates at Keyva have worked with many different organizations in various verticals to help in application modernization projects. These include things like refactoring existing applications, adding a wrapper over current applications so they can be consumed easily by DevOps processes, and more. If you’d like to have us review your environment and provide suggestions on what might work for you, please contact us at firstname.lastname@example.org.
Anuj joined Keyva from Tech Data where he was the Director of Automation Solutions. In this role, he specializes in developing and delivering vendor-agnostic solutions that avoid the “rip-and-replace” of existing IT investments. Tuli has worked on Cloud Automation, DevOps, Cloud Readiness Assessments and Migrations projects for healthcare, banking, ISP, telecommunications, government and other sectors.
During his previous years at Avnet, Seamless Technologies, and other organizations, he held multiple roles in the Cloud and Automation areas. Most recently, he led the development and management of Cloud Automation IP (intellectual property) and related professional services. He holds certifications for AWS, VMware, HPE, BMC and ITIL, and offers a hands-on perspective on these technologies.
