This blog post is going to cover the correlation between DevOps and Microservices, currently the two hottest topics in the IT industry. Although they have been around for some time, their importance has increased thanks to the container orchestration technologies such as Kubernetes and Openshift.
The technologies we talk about in this blog are part of DevOps. If it’s something in which you have an interest or you want to learn it then you can visit our previous blog to know more about the [DOFD] DevOps Foundation Certification.
Basics Of Microservices
Microservices is an architectural style that structures an application as a collection of services that are:-
- Highly maintainable and testable
- Loosely coupled
- Independently deployable
- Organized around business capabilities
- Owned by a small team
The microservice architecture provides rapid, frequent, and reliable delivery of large, complex applications. It also helps an organization to evolve its technology stack.
What Is Microservices Architecture
DevOps Basics
DevOps is a combined shift of corporate culture that revolves around the importance of communication and the tools that enable collaborative environments. DevOps teams are composed of cross-disciplined members who bring their own unique perspectives to work on bite-sized delivery one project at a time. This shift leads to a faster-paced environment in which deployments are made at steady, regular intervals with updates being pushed through in continuous integration or continuous delivery (CI/CD) system.
Benefits Of Microservices
The top 10 benefits that organizations realize from deploying microservices include:
- Localized complexity: Owners of the microservices only need to understand the complexity of their service. Other service owners only need to be aware of the capabilities a service provides, without having to worry about how it works internally. This knowledge compartmentalization and reduced complexity make it easier to create and manage large applications.
- Increased business agility: Microservices are relatively small and simple, and failure of a microservice is isolated —not the whole application— enabling developers to experiment with new processes, algorithms, and business logic. Microservices allow you to experiment and “fail fast.”
- Increased developer productivity: New developers can be incorporated into projects faster as it’s easier to understand a small, isolated piece of functionality than an entire monolithic application.
- Simplified debugging and maintenance: Developers can be much more productive when debugging code and performing maintenance.
- Better alignment of developers with business users: Since microservice architectures revolve around business capabilities, it is easier for developers to understand the user perspective and create microservices that are better aligned with the business.
- Future-proofed applications: When new innovations are incorporated and new or updated technology disrupts your software development process, microservice architectures make it easier to adapt by replacing or upgrading the services that are affected without impacting the entire application.
How Microservices Fit Into DevOps
DevOps Practices push the idealogy of dividing large problems into smaller pieces and tackling them in order as a team. Microservices have similar ideals of utilizing small teams for the creation of functional changes one step at a time. Furthermore, they can easily scale up or down without having any impacts on the resource allocations for the rest of the system.
The individual pieces created through the microservices architecture provide a plug and play functionality, hence creating an environment where continuous delivery pipelines can sustain a steady flow of deployments due to the reduced complexity of each deployment and lack of dependencies.
The combination of DevOps and microservices in the development, testing, and deployment of updates is the fastest method to increase the throughput of your teams and the overall quality of your services.
Microservices And DevOps: Creating Change Together
A microservices-based architecture introduces change, a change that is often well received by those creating modern applications. Those embracing that change are finding that productivity is increasing at an astonishing rate and solutions can be delivered much more quickly to those requesting flexible, scalable applications. For those in the field of DevOps fields, microservices bring some significant benefits, including:
- Deployability: They provide increased agility, which enables the roll-out of new versions of a service. That agility is due to shorter build, test, and deploys cycles.
- Reliability: A fault with a microservice is isolated to that microservice and its consumers.
- Availability: Releasing an update needs minimal downtime, whereas rolling out updates in the monolithic application normally needs a restart of the entire monolith.
- Scalability: Microservices can be independently scaled using pools, clusters, grids. This characteristic makes them perfect for the elasticity of the cloud.
- Modifiability: Microservices are flexible in terms of new frameworks, libraries, data sources, and other resources. As loosely coupled, modular components, microservices are easier to work with and provide support for dynamic discovery and binding via a registry.
- Management: Microservices leverage the agile methodology, where the development of the application is divided across teams that are smaller and independent.
