Tech Infrastructure: CARE

Generic Infrastructure Requirments

Infrastructure Requirements

High Availability Kubernetes Cluster:

• Implement a multi-master Kubernetes cluster with at least three master nodes to ensure high availability and fault tolerance.

• Deploy worker nodes across multiple geo-locations to avoid single points of failure.

Persistent Storage:

• Set up dynamic storage provisioning using custom storage classes and external storage solutions.

• Implement data replication and backup strategies for critical application data, ensuring data integrity and availability.

S3-Compatible Object Storage:

• S3-compatible object storage solution with high availability and scalability features.

• Configure data lifecycle policies for object versioning, retention, and automatic deletion, requiring careful data management.

• Enforce encryption at rest and in transit for all stored objects.

• Implement fine-grained access control using bucket policies, IAM roles, and access keys, ensuring only authorized users and applications can access the stored data.

Auto-Scaling:

• Implement custom Horizontal Pod Autoscalers (HPAs) with custom metrics. Set up Cluster Autoscaler to dynamically adjust the number of worker nodes based on resource utilization.

Security Policies and Network Policies:

• Enforce strict security policies, including PodSecurityPolicies and Network Policies, to control and isolate pods and services.

Custom Ingress Controllers:

• Implement custom Ingress controllers for routing and traffic management, including features like header rewriting, SSL termination, and authentication.

Advanced Networking:

• Configure a custom CNI (Container Network Interface) plugin with strict network policies to enforce micro-segmentation for maximum security.

• Ability to create Network Policy resources to control ingress and egress traffic between pods, making network access more secure.

Custom Resource Definitions (CRDs):

• Support for Custom Resource Definition for adding ClusterIssuers for Letsencrypt Certificate Authority or other certificates manager.

SMTP Server/Service:

An SMTP email server to handle email traffic for the domain the Care application is running on.

Role-Based Access Control (RBAC):

• Enforce fine-grained RBAC policies, ensuring only authorized personnel can access and manage specific resources within the Kubernetes cluster.

Centralized Logging and Error Detection:

• Configure centralized logging with log aggregation and analysis using tools like Sentry.

Secrets Management:

• Utilize advanced secret management solutions like HashiCorp Vault or Kubernetes native Secrets Store CSI Driver for secure storage and distribution of sensitive data.

Backup and Disaster Recovery:

• Establish a backup and disaster recovery strategy, including off-site backups, data snapshots, and automated failover procedures.

Compliance and Auditing:

• Implement Kubernetes audit logging and maintain compliance with industry-specific standards (e.g., CIS Kubernetes Benchmarks) for on-premises deployments.

Documentation and Training:

• Exhaustive documentation, training materials, and runbooks for onboarding and maintaining the Kubernetes setup.

Advanced Backup and Restore Procedures:

• Implement procedures for backup and restoration of the entire Kubernetes cluster, including etcd data, to ensure data integrity during failures.

Database Cluster Setup:

• Deploy a highly available database cluster (e.g., PostgreSQL, MySQL) with multiple read replicas for scalability and fault tolerance.

Data Partitioning and Sharding:

• Implement data partitioning and sharding strategies to distribute database load across nodes, requiring careful data modeling and management.

Database Encryption:

• Enforce encryption at rest and in transit for database data, utilizing advanced encryption methods and key management.

Database Backups:

• Configure automated database backup strategies with incremental and differential backups, ensuring data consistency and reliability.

Automated Failover:

• Set up automated failover mechanisms for the database cluster to minimize downtime in case of node failures.

Database Maintenance Jobs:

• To ensure database performance, schedule and manage maintenance jobs, such as index optimization, vacuuming, and data archiving.

Database Security Policies:

• Enforce strict database security policies, including role-based access control, audit logging, and database-level encryption.

Database Replication Lag Monitoring:

• Monitor and manage database replication lag to ensure data consistency across replicas, requiring timely intervention when lag exceeds thresholds.

Database Version Upgrades:

• Planned database version upgrades with minimal downtime.

Database Scaling:

• Implement auto-scaling policies for the database cluster, dynamically adjusting resources based on workload demand.

Continuous Deployment (CD):

• Set up continuous deployment to automatically promote successfully tested changes to production without manual intervention.

Rollback Procedures:

• Define rollback procedures and automate them in case of deployment failures or issues in production.

Environment Configuration Management:

• Manage environment-specific configurations and secrets separately from the application code.

Monitoring and Alerting:

• Track application performance and set up alerts for anomalies in deployments.
