Tessell is a cloud-native Database-as-a-Service that runs Oracle workloads on Azure within the customer's own tenancy, using Microsoft Azure Consumption Credits and high-performance NVMe compute shapes. This strategic guide explains how Oracle estates can be moved to Azure through a phased approach that covers migration, ongoing management, and modernization, without forcing a rip-and-replace decision. It frames the common challenges around price performance, governance, production architecture, and support, then walks through where cost optimization actually comes from once workloads are in the cloud. The guide is positioned as a planning resource, complementing existing Azure reference architectures for Oracle rather than replacing them.
What is inside
The Tessell-on-Azure deployment model, including Lsv3 and Lasv3 NVMe compute shapes delivering 2 to 3 million IOPS for production Oracle workloads
Four migration challenges Tessell addresses: price performance, customer-controlled OS and security agents, mapping Oracle HA to availability zones with cross-region DR, and 24/7/365 production support
The Lift and Shine approach to post-migration lifecycle operations, covering patching, upgrades, security agent integration, and unified visibility across on-premises and Azure
Four cost optimization levers: idle resource consolidation, cost-optimized compute shapes for DevSecOps pipelines (which can account for up to 40% of compute), tiered storage, and CPU license reduction
How Tessell fits alongside Exadata@Azure following the September 2023 Microsoft-Oracle partnership, including mixing dev, test, and production across both infrastructures
Concrete next steps including no-cost POC with AWR-based performance benchmarking, workload analysis, and TCO assessment
Who is this for
This guide is written for IT leaders, database architects, and Oracle estate owners planning a migration from on-premises Oracle to Azure. It walks through the migration, management, and cost optimization decisions involved, along with how Tessell fits alongside native Azure and Exadata@Azure options. Use it to align stakeholders on the migration approach before a POC. It complements, but does not replace, hands-on workload validation.
