As cloud-agnostic experts, we help you analyze the trade-offs and select the platform that best aligns with your technical requirements, budget, and long-term strategy.

How do you ensure the security of our validator keys?

Protecting validator keys is our highest priority. We employ a multi-layered strategy using cloud-native Hardware Security Modules (HSMs) like AWS KMS, Azure Key Vault, or Google Cloud HSM. These services ensure that private keys are generated and stored in tamper-resistant hardware and are never exposed in plaintext. Access is strictly controlled through IAM policies, and all signing operations are performed within the secure HSM environment, providing the highest level of protection against theft.

Can you help us reduce our existing cloud costs?

Absolutely. Our FinOps practice specializes in cloud cost optimization. We start with a thorough audit of your current infrastructure to identify waste, such as oversized instances, unattached storage, and idle resources. We then implement strategies like resource rightsizing, leveraging spot instances for non-critical workloads, and purchasing Reserved Instances or Savings Plans for predictable workloads, often resulting in cost savings of 30-50% without impacting performance.

What does your 24/7 managed service include?

Our 24/7 managed service is a comprehensive SRE (Site Reliability Engineering) offering. It includes proactive monitoring of all infrastructure and blockchain-specific metrics, automated alerting for potential issues, regular security patching and software updates, incident response with defined SLAs, and performance tuning. Essentially, we take complete ownership of your infrastructure's health and availability, allowing your team to focus entirely on application development.

How do you handle blockchain client updates?

We use a zero-downtime, rolling update strategy, especially in a Kubernetes environment. The process is automated through our CI/CD pipelines. A new version of the blockchain client is packaged into a Docker container and pushed to a registry. The pipeline then gradually replaces old nodes with new ones, one at a time, ensuring the cluster maintains quorum and continues to operate without interruption throughout the update process. We also perform extensive testing in a staging environment before any mainnet deployment.
