Tessell is a fully managed Database-as-a-Service for running Oracle workloads on AWS using a Bring Your Own Account model, with the data plane staying inside the customer's own AWS subscription. This technical reference guide covers the full scope of the service, from deployment models and subscription onboarding to HPC compute shapes, SLOB benchmarks against Amazon RDS, availability architectures, SLAs, security controls, and provisioning through both the Tessell console and Terraform. It includes hands-on sections for those who want to evaluate or deploy the service directly. The guide is structured as a complete reference document rather than a high-level overview.
What is inside
The two deployment models, Virtual Private Tessell and Virtual Private Tessell @ Customer (BYOA), along with the CloudFormation-based subscription onboarding flow and the IAM permissions Tessell requests
The HPC compute shape catalog covering i3, i3en, and i4i instance families, with read and write IOPS specifications scaling up to 3.2 million read IOPS on the largest shape
A SLOB benchmark comparing Tessell on AWS against Amazon RDS at the same cost, showing 165,569 IOPS versus 15,010 IOPS on identical 8 vCPU, 64 GB RAM shapes
The full availability matrix covering single instance, single-zone HA, multi-AZ HA, and cross-region DR, with RTO and RPO targets for both planned and unplanned events
The 99.99% monthly uptime SLO, severity definitions, response time commitments (15 minutes for Severity 1), and SLA exclusions
Security posture including SOC 2 Type II certification, encryption at rest with BYOK, SSL, IP whitelisting, and the Availability Machine plus Dataflix model for governed data sharing across UAT, QA, and dev environments
A step-by-step Quickstart for provisioning an Oracle database through the Tessell console, plus a working Terraform script using the tessell-cloud provider
Who is this for
This guide is written for DBAs, database architects, and platform engineers evaluating or operating Oracle workloads on AWS through Tessell. It covers both the architectural reasoning (deployment models, availability tiers, benchmarks, SLAs) and the hands-on steps to provision a database, making it useful for technical evaluation as well as deployment. Built as a single-source reference for evaluation. The Tessell product documentation and a guided POC remain the path to production rollout.
