Cloud Native Application Testing
Introduction
Cloud Native application service refers to a program that is designed for cloud computing architecture. It supports and follows the concepts of DevOps. Cloud native applications testing operate in a dynamic, flexible, and shared environment. Based on the demand the application can be scaled up or down which has a positive impact on the cost. Their agile nature helps on quick deployment. Cloud-native applications testing services are portable, offer high scalability, and can be modified as per requirement, all of which can be performed without changing the code.
Definition
Cloud native application Testing Services can be defined as Testing each component individually as well as end-end workflow.
Significance
The Importance of Cloud-Native Application Testing
Cloud native testing is critical for handling the challenges of cloud native applications. However, it has been demonstrated that deployment models, service models, and other key characteristics of cloud computing can have a significant impact on cloud testing approach or strategy. Other non-functional aspects that should be addressed by the testing teams include performance, security, compatibility, environment management, integration with various interfaces, user experience, and much more. Embracing Cloud-native testing approach enhances DevOps in Software Development Life Cycle by including agile practices for cloud development and it can be based on cloud-native infrastructure.
Our Approach
Thought Frameworks Approach towards Cloud-Native Application Testing Services
We focus on the seven following areas to design the possible scenarios that play a key-role in production.
Scalable
- Service scalability
- Usage of cache
- Cache performance across services when requests are stateless
- Consequences when instances are no longer required
Dynamic Environments
- Analyze how the feature is deployed and the key distributed elements to the system
- Cross-examine the availability of a feature dependencies
- Identify the feature recovery process.
Resilient
- Kubernetes can perform rolling restarts but how do we gracefully shutdown and release client threads
- Understanding overloads on the nodes when traffic is being routed.
- Understand the system deterioration rate.
- System responsiveness when legacy systems are unavailable
Manageable
- Analysis of Time and Effort
Observable
- Capturing metric requirements
- Archived and searchable logs
- Traceability of application.
Robust Automation
- Validate deployment simultaneously
- Negative task-based scenarios are performed in terms of scalability and reliability.
Frequent and predictable high-impact change
- What are the service dependencies
- Are there any breaking changes
- Continuous delivery over Continuous deployment
- How do we run end to end tests while a deployment is in progress
- If it fails, how does it rollback
- What should happen.
Repercussion
What happens when you don’t do Cloud-Native Testing?
A Cloud Native Application Testing has numerous points of failure due to a large number of moving components, which are loosely coupled. Failures can occur for a number of reasons and can impact the business in the following ways -
- Releases are delayed or slow.
- Infrastructure management is a challenge.
- Cost of Infrastructure Increases.
- The System's Reliability is Affected.
- Issues with Scalability.
Strategies
Thought Frameworks Cloud Native Testing Strategy
Thought Frameworks Cloud Native Testing Strategy
With the introduction of tools to orchestrate applications in different settings, the possibility is offered to automate the execution of our native cloud native test strategy within these pipelines.
Quality Assurance team, developers and product owners work collaboratively to contribute to ensuring that best value is achieved. The Cloud Native Test Quality Assurance Charter and the principles of chaos can help to ensure that production is reliable.
It is crucial to analyze and, if necessary, to integrate the results of the exploratory tests (using chaos or cloud native methodologies) in all automated regression packages. Do not forget, we need a solid, quick and valuable test suite, not everything must be automated.
Canary testing is one method used to validate production features. It requires the deployment of a feature to a subset of users without their knowledge before it is extended to a broader population.
Methodology
Cloud Native App Testing Services Bug Hunt Process
We focus on the three pillars of Cloud Native Testing Services in the Software Development Life Cycle.
Cultural change from silos to proper DevOps
The goal of DevOps is to get everyone to work in unison by working on the same tools and setting priorities. DevOps is required to practice cloud-native, even though it is not necessary to run the applications in the cloud to be cloud-native services.
Technical change which relates to the way an application is built
For example moving from Monolith to microservices.
Organizational change - A Collaborative effort to achieve the goal
Delivering business action items in a breeze - since there is a faster feedback loop between developers and end users resulting in quick delivery of software application development
Cloud-Native Application Testing Services
Cloud-Native technologies comprises a distinct series of steps which lay the foundation for managing a container-based, fault-tolerant environment that enables speed and resiliency to be deployed across all types of services.
To demonstrate resilience every organization is developing alternatives this effort has resulted in a faster digital transition. As a result, cloud adoption and cloud-native application services development are on the rise, which is likely to help accelerate the process. With increasing customer demand, cloud technologies have proven to be critical in providing enterprises with resiliency. It gives them the ability to be flexible and scale up or down on demand.
Execution
Ways to Implement Cloud-Native DevOps Testing
- Aligning with the microservices patterns
- Using Containerization
- Following declarative communication pattern
- Deploying container orchestration
- 12-factor application principles are employed while writing the code
- Increasing automation in CI\CD pipelines
- Exposing health check
- Collecting telemetry data
