Choosing an Oracle Cloud Infrastructure Services Provider: Our Take on What the 2026 Gartner® Market Guide Says

Choosing an IT partner for a highly specialized environment brings inherent risk. Oracle Cloud Infrastructure (OCI) work requires a level of technical depth that’s hard to evaluate from a sales conversation alone, which is why buyers look for third-party validation before signing a contract. An independent assessment gives you a reference point outside of a vendor’s own marketing.

We think Gartner has built its reputation over decades as one of the most trusted sources for that kind of independent validation, and Buchanan Technologies has been named for the second consecutive year in the 2026 Gartner Market Guide for Oracle Cloud Infrastructure Professional and Managed Services.

This article breaks down our take on what the Market Guide actually is, what its 2026 edition says about the current state of the OCI services market, and the specific factors buyers should weigh when evaluating an OCI provider.

Gartner Market Guides Give Buyers the Market Context They Need

We believe that there’s a common misconception that a Gartner Market Guide works like a Magic Quadrant, positioning vendors on the basis of Ability to Execute and Completeness of Vision. A Market Guide defines a market and explains what clients can expect it to do in the short term. With the focus on early, more chaotic markets, a Market Guide does not rate or position vendors within the market, but rather more commonly outlines attributes of representative vendors that are providing offerings in the market to give further insight into the market itself.

The 2026 edition covers consulting, implementation, and ongoing management services for Oracle and non-Oracle workloads running on Oracle Cloud Infrastructure. It was authored by Karl Rosander and Tobi Bet and published May 4, 2026.

For a buyer, the Market Guide is most valuable when it’s used as a shortlisting tool and a source of independent market context. Because, in our opinion, the Gartner research process is independent of any vendor’s marketing team, the report gives IT and procurement leaders a reference point that doesn’t come from a sales deck. Considering that a decision of this magnitude affects budget, timeline, and long-term operational risk, having independent validation is essential for making the right choice.

What the 2026 Edition Says About the OCI Services Market

This year’s report reveals several themes about the OCI provider market. First, enterprises have largely moved past debating whether OCI is a viable platform and are now focused on deploying and optimizing workloads already running on it. Demand for Oracle managed cloud and hybrid cloud services continues to grow as more organizations move mixed Oracle and non-Oracle workloads into the same environment.

AI-driven operations and cost optimization are becoming important factors that buyers expect a provider to deliver on an ongoing basis. The specialist talent pool for OCI work is also not keeping up with demand, which turns bench depth into a real procurement risk. A provider can hold every relevant certification and still lack the staffed capacity to support a client through a major upgrade or an unplanned incident. That lack of capacity may not show up during the sales process, but it will likely be revealed when you need it most, after the contract’s been signed.

Five Things to Evaluate in Any OCI Services Provider

Gartner published guidance for sourcing and procurement leaders is to evaluate providers against a specific cloud strategy, timeline, cost objectives, and business outcomes. To us, the following five factors translate that guidance into practical questions a buyer can bring to a provider conversation.

Oracle and OCI Skills Depth

Certifications are easy to list on a slide and hard to verify in practice. The more useful question is how many specialists are actually staffed to client accounts day to day, and whether that staffing holds steady once the contract is signed. Ask a provider to walk through the specific team that would support your environment, not a generic bench count.

Documented SLAs and Business Outcomes

General managed services references don’t tell you much about Oracle-specific performance. Ask for documented outcomes from comparable Oracle environments, ideally with the same complexity of ERP, database, or cloud footprint your organization runs. A provider that can only point to broad IT service metrics hasn’t demonstrated Oracle-specific accountability. Ask to see an anonymized SLA report from an existing Oracle client. The language in a sample contract can be misleading. An actual report shows you what they’re actually capable of delivering.

Full Oracle Stack Experience

Managing Oracle EBS, Fusion Cloud, Oracle Database, and OCI together requires a different level of coordination than managing any single layer in isolation. Ask whether the provider’s team handles the full stack as one coordinated practice or hands pieces off to different specialists who rarely talk to each other. When ownership is fragmented, troubleshooting can be slow when something breaks in multiple layers.

Ongoing Cost Optimization Practice

Migration gets most of the attention in a sales conversation, but the bigger long-term cost risk occurs after go-live. Providers who stop at migration and leave FinOps entirely to the client are leaving real value on the table. Ask what an ongoing cost optimization engagement actually looks like month to month, after the initial project kick-off.

Multicloud Capability

The 2026 report will help SPVM leaders choose from a representative list of service providers when assessing, migrating and managing Oracle and non-Oracle workloads on OCI. Even organizations committed to OCI benefit from a provider that understands how Oracle behaves across cloud platforms, since that experience translates into better architecture decisions on any single platform.

Why We Believe Buchanan Is in the Market Guide Two Years Running

Buchanan has now met Gartner evaluation criteria for this report in back-to-back years, which we think reflects how well-established our capabilities in this area are. Buchanan’s Oracle practice spans Oracle E-Business Suite migrations onto OCI, Oracle Fusion Cloud management, OCI migrations, Oracle performance tuning, and Oracle managed services. Our Oracle engagements aren’t just project handoffs. They’re part of an ongoing practice, and the scope of what we deliver aligns directly to the coverage areas the report evaluates.

Client outcomes cited include a 30% OCI cost reduction, a 94% performance improvement, and a 90% infrastructure reduction. Here’s what one client had to say about working with us: “We work with them annually for System Health Check. They have an industry-leading expert who goes above and beyond each year to identify bottlenecks and code inefficiencies, as well as provide solutions. Their ability to diagnose issues quickly and thoroughly has gained our customer loyalty."

Our Oracle relationship extends beyond the managed services practice into a formal partner status, which impacts how quickly our team can escalate complex issues or get early visibility into platform changes that affect client environments.

Buchanan’s inclusion in the Market Guide isn’t just a Gartner acknowledgement or recognition to us. It is, however, one data point worth weighing alongside direct conversations with any Oracle managed services or Oracle Cloud Infrastructure services provider under consideration.
