Tassel Turner is a cloud-native platform fully hosted with Amazon Web Services (AWS).
The Tassel Turner architecture takes full advantage of AWS services from caching middleware to workload queuing so that we can provide a reliable platform at all times.
Your platform deployment is isolated in a private cloud network with strict separation of resources such as databases, web services, email, files, and logs.
This doesn't only guarantee security but also ensures there is no chance of other system activity impacting yours, and no risk of data contamination from shared sources.
If a large number of users cause a traffic spike and the system begins to respond slowly, additional servers are automatically launched to handle the traffic as needed.
To keep the throughput high, most activity such as ticket generation is offloaded to a queuing system where it won't impact the user experience.
During development we perform various stress tests to catch any bottlenecks, design around failures, and continually improve the performance of platform features.
A faster more efficient system will always be more reliable.
Platform upgrades are performed in a deployment pipeline that employs test suites, static analysis tools, and system health checks to prevent bugs and quality regressions.
We target a demanding 98% C1 test coverage for all Tassel Turner systems.
Our platform infrastructure is designed to tolerate failures or else failover in the event of a major disaster like a regional outage.
No servers, networks, or services are managed by hand, allowing our incident response team to rapidly and reliably restore your deployment as needed. In fact we make it a point to practice test drills that ensure we can meet strict recovery time objectives.
We can provide a sandbox environment where you and your IT team can perform your tests and measurements against an isolated production-like deployment.
Data loss can occur from rare events like disk failures, or from user errors and misuse of automation or batch processing.
Tassel Turner helps recover from all these scenarios with a configurable backup period of one-minute point-in-time recovery for all platform data. User audit logs provide a more detailed control over records with an option to rollback modified data to previous versions.
Tassel Turner web services are hosted in a regional data center as close to your institution as possible.
This isn't only for privacy laws, but also ensures users a low latency when using web applications even when internet access is poor.
Of course we back up our reliability commitment with an industry-leading 99.95% uptime SLA (max 21.56 min/month) for all platform services.
Tassel Turner is wholly owned and operated by Bellwether, and as such we maintain a detailed business continuity plan to ensure that the platform remains available and functional in the extremely unlikely case that Bellwether can no longer operate. This includes contingencies such as placing source code and relevant IP in escrow and reserving hosted resources in advance for the full duration of contracts.
