Migrating from IBM DataPower or TIBCO requires separating gateway routing from protocol-specific functions. This guide covers a sidecar approach: deploy STOA for REST/JSON traffic, federate identity via OIDC, and keep legacy systems for B2B protocols where they excel.

IBM DataPower and TIBCO BusinessWorks represent two of the most deeply embedded integration platforms in enterprise IT. Both handle critical workloads — security token services, multi-protocol mediation, B2B gateway functions — that organizations depend on daily.

This guide provides a practical assessment of migration approaches for organizations evaluating modernization paths from these platforms.

MuleSoft migrations are most effective when you separate the API gateway layer from integration flows. Move Experience APIs (routing, auth, rate limiting) to open-source gateways while keeping Anypoint for DataWeave transformations and complex connectors.

MuleSoft Anypoint has become one of the most widely deployed integration platforms in enterprise IT. Since Salesforce's acquisition in 2018, the platform has deepened its ties to the Salesforce ecosystem while organizations face evolving requirements around AI agent support, European data sovereignty, and infrastructure cost management.

This guide provides a practical assessment of when MuleSoft migration makes sense, what the challenges are, and how to approach it without disrupting existing integrations.

Connecting AI agents to enterprise APIs is the next frontier of digital transformation — and the next frontier of security risk. As organizations deploy AI agents built on Claude, GPT, Gemini, and open-source models, these agents need access to internal systems: databases, CRMs, ERPs, payment processors, and more. The question is not whether to grant this access, but how to do it without opening a new attack surface.

If you are evaluating an Apigee alternative, you are not alone. Since Google absorbed Apigee into its cloud platform, a growing number of organizations have found themselves facing rising costs, deepening vendor lock-in, and an increasingly opaque product roadmap. The good news: open-source API gateways have matured to the point where migration is not just feasible — it is often a strategic improvement.

Building a multi-tenant API gateway is one of the hardest infrastructure challenges in platform engineering. You need strong isolation between tenants, shared infrastructure for efficiency, and the ability to scale without multiplying operational complexity. After years of building multi-tenant API platforms — and applying those lessons to STOA on Kubernetes — here is what we learned.

This article is part of the Open-Source API Gateway 2026 series, covering architectural patterns for modern API infrastructure.

The European regulatory landscape has shifted dramatically for organizations managing digital infrastructure. DORA NIS2 compliance is no longer a future concern — it is an immediate operational requirement for any organization operating API gateways in financial services, healthcare, energy, or critical infrastructure sectors across the EU.

API management in Europe is no longer just a technical decision. It is a regulatory, legal, and strategic one. The convergence of NIS2, DORA, GDPR enforcement, and the US CLOUD Act has created a landscape where the jurisdiction of your API gateway matters as much as its throughput. European organizations that route sensitive data through US-controlled infrastructure — even when hosted on EU soil — face compliance risks that no amount of contractual clauses can fully mitigate.

If you are evaluating API gateways in 2026, Kong is almost certainly on your shortlist. It deserves to be. Kong is a mature, battle-tested platform with a massive plugin ecosystem and years of production deployments. So why did we build STOA as a Kong alternative? Not because Kong is bad — but because the problem has changed.

The open-source API gateway landscape in 2026 includes Kong, Envoy, APISIX, Tyk, Gravitee, and STOA. This guide compares their architectures, MCP support, multi-tenancy, and licensing — with a focus on AI-readiness and European sovereignty.

The open source API gateway landscape in 2026 looks very different from what it was just two years ago. The rise of AI agents, the Model Context Protocol (MCP), and stricter European regulations have reshaped what organizations expect from their API infrastructure. This article provides an honest comparison of the leading open-source gateways and where each one excels.

Migrating from Software AG webMethods API Gateway™ to an open-source alternative is achievable in 4-6 months using a phased, zero-downtime approach. This guide covers what makes webMethods migrations distinct — the Integration Server (IS) dependency, the Designer-based policy model, the IBM licensing entanglement — and provides a concrete roadmap for platform teams ready to act.
