1. Adopting Resilient Frameworks: Architects can make use of popular resilient frameworks such as Kubernetes, Docker Swarm or Apache Mesos, to enable their applications to recover from issues in real-time. These frameworks are specifically designed to handle failures in shared services or infrastructure and provide automated mechanisms for recovery and reliability.
2. Continuous Integration and Deployment (CI/CD): One of the key principles of resilience is continuous improvement. Architects can incorporate CI/CD tools like Jenkins, Travis and CircleCI in their development cycles to automate code testing and deployment. This allows for rapid feedback loops and enables the team to spot and address issues earlier on.
3. Microservices: Monolithic architecture presents a single point of failure, and any downtime of the system can lead to disruption in the entire application. Breaking the application down into granular microservices that each serve a specific function improves the overall resilience of the system. This architecture makes it easier to isolate and address issues and makes the application more fault-tolerant to fix related problems.
4. Load Balancing and Scaling Technologies: Proper load balancing and scaling technologies will ensure that an application can withstand fluctuations in traffic rates and handle routing traffic to instances of applications that are not facing downtime. Using containerization tools such as Docker or cloud service auto-scaling capabilities can automate the process of scaling and reduce the human error that leads to overscaling or underscaling.
5. Cloud Native Infrastructure: Cloud providers offer resilient infrastructure for their services by providing redundancy mechanisms and failover solutions as part of their products. Architecting applications in the cloud ensures a high degree of the application uptime with less dependency on individual data centers. Additionally, cloud providers manage disaster recovery, backup technology, network security, incident response and data encryption features that make your application more resilient.
