Introduction<\/h2>\n\n\n\n<p>Oracle Database Service for Azure is a Multicloud service that lets you provision and operate select Oracle Cloud Infrastructure (OCI) Oracle Database offerings from within Microsoft Azure, with tight integration into Azure-native workflows (identity, portal, and networking). It is designed for teams that build applications on Azure but want Oracle database capabilities delivered and managed as an Oracle Cloud service.<\/p>\n\n\n\n<p>In simple terms: you keep your app tier in Azure, and you consume an Oracle-managed Oracle Database service through an Azure-centric experience\u2014so your developers and operators don\u2019t have to \u201cleave Azure\u201d for day-to-day provisioning and basic lifecycle actions.<\/p>\n\n\n\n<p>Technically, Oracle Database Service for Azure provides an Azure control-plane experience for deploying Oracle-managed database infrastructure that is part of Oracle Cloud. The data plane remains Oracle Database, operated under Oracle Cloud\u2019s service model. This typically includes Azure portal-based provisioning, private networking patterns, and a shared operational model between Oracle and Microsoft (exact responsibilities vary by offering\u2014verify in official docs).<\/p>\n\n\n\n<p>The problem it solves is common in enterprise and regulated environments: teams standardize on Azure for applications and security tooling, but require Oracle Database capabilities (including Oracle-managed services) without running self-managed Oracle Database on Azure VMs or building brittle cross-cloud networking patterns.<\/p>\n\n\n\n<blockquote>\n<p>Naming note (verify in official docs): Oracle and Microsoft also market a closely related offering as <strong>Oracle Database@Azure<\/strong>. In many Azure user experiences and listings, you may see \u201cOracle Database Service for Azure\u201d used to describe the Azure-native service entry point. This tutorial uses <strong>Oracle Database Service for Azure<\/strong> as the primary service name, as requested, and calls out related names only for clarity.<\/p>\n<\/blockquote>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">2.

Why use Oracle Database Service for Azure?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Business reasons<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Azure-first standardization:<\/strong> Organizations with strong Azure procurement, governance, and platform standards can consume Oracle database services without forcing teams to adopt a parallel cloud console for basic tasks.<\/li>\n<li><strong>Reduced delivery risk:<\/strong> Avoids self-managed Oracle Database on IaaS (patching, backups, HA architecture, and skilled DBA staffing remain major risk drivers).<\/li>\n<li><strong>Vendor support clarity:<\/strong> You can align application hosting on Azure with an Oracle-managed database service model, potentially simplifying support paths compared to running Oracle Database on generic VMs.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Technical reasons<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Low-latency private connectivity patterns<\/strong> (compared to public endpoints or ad-hoc VPN-based designs), depending on region and architecture.<\/li>\n<li><strong>Access to Oracle Cloud database service capabilities<\/strong> (service-dependent), while keeping the app tier in Azure.<\/li>\n<li><strong>Cleaner separation of concerns:<\/strong> Azure for application infrastructure; Oracle Cloud-managed database for database operations.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Operational reasons<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Portal-driven workflows:<\/strong> Faster onboarding for teams already trained on Azure portal, Azure RBAC, and Azure tagging.<\/li>\n<li><strong>Managed lifecycle:<\/strong> Patching and backups are generally service-managed on the Oracle side (verify exactly what is managed for your chosen database offering).<\/li>\n<li><strong>Standardized environments:<\/strong> Easier to establish repeatable provisioning patterns and guardrails.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Security\/compliance reasons<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Private networking and controlled exposure:<\/strong> Better posture than public database endpoints.<\/li>\n<li><strong>Central governance on Azure side:<\/strong> Resource groups, tags, RBAC, policy, and logging integration can help satisfy organizational controls (scope varies).<\/li>\n<li><strong>Oracle database controls:<\/strong> Oracle Database security features and Oracle-managed service practices can support regulated requirements (you still must design your own controls).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Scalability\/performance reasons<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Scale characteristics<\/strong> depend on the underlying Oracle database offering you provision (Autonomous vs Exadata-based vs others\u2014verify what\u2019s supported).<\/li>\n<li><strong>Performance consistency<\/strong> can be improved by using Oracle-managed engineered systems offerings where applicable, compared to self-managed on generic IaaS.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">When teams should choose it<\/h3>\n\n\n\n<p>Choose Oracle Database Service for Azure when:\n&#8211; Your <strong>application tier must stay in Azure<\/strong> for governance, proximity to Azure services, or organizational policy.\n&#8211; You need <strong>Oracle Database capabilities<\/strong> and prefer <strong>Oracle-managed<\/strong> database operations.\n&#8211; You want <strong>private, controlled connectivity<\/strong> between Azure and the database service.\n&#8211; You have a <strong>clear cost model<\/strong> that accounts for cross-cloud networking, procurement, and database licensing\/service SKU.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When teams should not choose it<\/h3>\n\n\n\n<p>Avoid or reconsider if:\n&#8211; You need a database that is <strong>native Azure PaaS only<\/strong> with no Oracle dependencies (Azure SQL, Cosmos DB, PostgreSQL services, etc.).\n&#8211; Your region is not supported, or your workload requires a feature not yet available in Oracle Database Service for Azure.\n&#8211; You cannot accept the <strong>operational split<\/strong> (Azure for app ops, Oracle Cloud for database ops).\n&#8211; You require full OS-level control of the database host (then you\u2019re in IaaS\/self-managed territory).\n&#8211; Your workload is extremely cost-sensitive and would be better served by a simpler single-cloud managed database with lower licensing\/service costs.<\/p>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">4. Where is Oracle Database Service for Azure used?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Industries<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Financial services<\/strong> (core banking integrations, risk, payments, regulatory reporting)<\/li>\n<li><strong>Telecom<\/strong> (billing, mediation, customer systems)<\/li>\n<li><strong>Retail<\/strong> (order management, inventory, pricing engines)<\/li>\n<li><strong>Manufacturing<\/strong> (ERP integrations, supply chain)<\/li>\n<li><strong>Healthcare<\/strong> (claims processing, clinical systems\u2014subject to compliance)<\/li>\n<li><strong>Public sector<\/strong> (where Oracle Database is standardized but apps are shifting to Azure)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Team types<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Platform engineering teams building <strong>standard landing zones<\/strong> on Azure<\/li>\n<li>DBA and database platform teams who want <strong>Oracle-managed services<\/strong> rather than self-hosted<\/li>\n<li>DevOps\/SRE teams operating microservices on AKS with Oracle database dependencies<\/li>\n<li>Security teams enforcing <strong>private access<\/strong> and centralized governance<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Workloads<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Oracle-backed line-of-business applications<\/li>\n<li>Mixed stacks: .NET\/Java services on Azure + Oracle database backends<\/li>\n<li>Analytics\/reporting systems that rely on Oracle features (verify fit)<\/li>\n<li>ERP\/CRM integrations where Oracle Database is mandated<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Architectures<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hub-and-spoke VNets with centralized ingress\/egress<\/li>\n<li>Private endpoint and private DNS patterns<\/li>\n<li>Multicloud governance: Azure Policy + Oracle Cloud controls<\/li>\n<li>Hybrid identity designs involving Entra ID (Azure AD) and Oracle Cloud IAM<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Production vs dev\/test usage<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Production:<\/strong> Best when supported regions and HA\/DR requirements can be met, and network\/security controls are well designed.<\/li>\n<li><strong>Dev\/test:<\/strong> Valuable for realistic integration testing (Azure app tier + Oracle database service) without building self-managed Oracle DB clusters.

Top Use Cases and Scenarios<\/h2>\n\n\n\n<p>Below are realistic scenarios where Oracle Database Service for Azure is commonly evaluated. For each, confirm supported capabilities in your target region and offering (verify in official docs).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1) Azure microservices that require Oracle Database<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> AKS-hosted services need Oracle Database features and performance, but teams don\u2019t want to self-manage Oracle on VMs.<\/li>\n<li><strong>Why this service fits:<\/strong> Oracle-managed database operations with Azure-centric provisioning and private connectivity.<\/li>\n<li><strong>Example:<\/strong> A payments API on AKS uses Oracle as the system-of-record; the team provisions the database through Azure and connects privately.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2) Modernize app tier to Azure while keeping Oracle database managed<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> Legacy apps are being refactored; database remains Oracle, but ops wants managed services.<\/li>\n<li><strong>Why this service fits:<\/strong> Lets you move the app tier to Azure without forcing a full database migration away from Oracle.<\/li>\n<li><strong>Example:<\/strong> A Java monolith is split into services on Azure; Oracle database remains the authoritative store.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3) Replace self-managed Oracle Database on Azure IaaS<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> Oracle on Azure VMs is operationally heavy (patching, backups, HA).<\/li>\n<li><strong>Why this service fits:<\/strong> Offloads a portion of operational burden to Oracle-managed service models.<\/li>\n<li><strong>Example:<\/strong> A team running Oracle RAC-like patterns on VMs migrates to an Oracle-managed database service consumed via Azure.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">4) Standardize procurement through Azure subscription governance<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> Procurement and cost management are centralized on Azure; OCI separate billing is hard to allocate.<\/li>\n<li><strong>Why this service fits:<\/strong> Provides Azure-aligned provisioning and often Azure-friendly billing constructs (verify your agreement).<\/li>\n<li><strong>Example:<\/strong> A cost center uses Azure tags and budgets; database spend is aligned with Azure cost governance.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">5) Private connectivity for regulated workloads<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> Public endpoints are disallowed; strict network controls required.<\/li>\n<li><strong>Why this service fits:<\/strong> Designed around private connectivity patterns between Azure VNets and the Oracle-managed database endpoints.<\/li>\n<li><strong>Example:<\/strong> A healthcare claims app on Azure requires private database access with audited network paths.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6) Oracle-backed SaaS on Azure with per-tenant isolation<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> Multi-tenant SaaS needs strong isolation while staying on Azure.<\/li>\n<li><strong>Why this service fits:<\/strong> You can provision separate database instances\/tenants (as supported) and isolate network access per environment.<\/li>\n<li><strong>Example:<\/strong> A B2B SaaS provisions a dedicated database per enterprise customer and restricts connectivity to a dedicated VNet.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">7) Data residency or locality constraints (where supported)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> Data must remain in a particular geography aligned to Azure region availability.<\/li>\n<li><strong>Why this service fits:<\/strong> Oracle database service delivery is aligned to specific Azure regions where the service is available (verify).<\/li>\n<li><strong>Example:<\/strong> An EU-hosted app must keep data in-region; uses Oracle Database Service for Azure in a supported EU Azure region.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">8) Azure-native CI\/CD provisioning of Oracle databases (infrastructure as code)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> Teams need repeatable environments for testing.<\/li>\n<li><strong>Why this service fits:<\/strong> Azure ARM\/Bicep\/Terraform patterns may apply on the Azure side (verify provider support).<\/li>\n<li><strong>Example:<\/strong> A pipeline spins up a short-lived Oracle database service instance for integration tests, then tears it down.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">9) Consolidate monitoring entry points for Azure ops teams<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> Operators want a single operations \u201cpane\u201d in Azure.<\/li>\n<li><strong>Why this service fits:<\/strong> Provides an Azure portal experience and may integrate with Azure monitoring constructs at least for resource health (depth varies).<\/li>\n<li><strong>Example:<\/strong> NOC uses Azure dashboards for service health; DBAs use Oracle-native views for database internals.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">10) Gradual migration away from Oracle without big-bang cutover<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> You plan to move to another database long-term, but need Oracle now.<\/li>\n<li><strong>Why this service fits:<\/strong> Keeps Oracle database delivery manageable while you decouple the app.<\/li>\n<li><strong>Example:<\/strong> New services are built on PostgreSQL, but legacy modules still need Oracle for 12\u201324 months.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">11) Disaster recovery patterns spanning Azure and Oracle-managed database services<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> You need DR with clear RPO\/RTO targets.<\/li>\n<li><strong>Why this service fits:<\/strong> Some Oracle database offerings include HA\/DR features; integration design can keep app tier in Azure (verify DR options).<\/li>\n<li><strong>Example:<\/strong> Primary app in Azure region A with Oracle database service; standby\/replica options depend on supported Oracle service features.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">12) Development teams that need Oracle features but don\u2019t have Oracle DBA capacity<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Problem:<\/strong> Teams ship fast but lack deep DBA skills.<\/li>\n<li><strong>Why this service fits:<\/strong> Managed service reduces DBA toil; teams still must understand schema design and SQL performance.<\/li>\n<li><strong>Example:<\/strong> A product team uses a managed Oracle database service with guardrails and limited admin access.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">6.

FAQ<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>\n<p><strong>Is Oracle Database Service for Azure the same as Oracle Database@Azure?<\/strong><br\/>\n   They are closely related in positioning. Oracle and Microsoft use <strong>Oracle Database@Azure<\/strong> as a major brand for delivering Oracle database services in Azure. In Azure, you may encounter the entry point as <strong>Oracle Database Service for Azure<\/strong>. Confirm naming and scope in official docs for your tenant.<\/p>\n<\/li>\n<li>\n<p><strong>Do I need an Oracle Cloud account\/tenancy?<\/strong><br\/>\n   Many Multicloud offerings require an Oracle-side service context even if the experience is Azure-native. The onboarding flow in Azure will indicate whether you must link or create Oracle-side context. Verify in official docs.<\/p>\n<\/li>\n<li>\n<p><strong>Can I connect without public internet access?<\/strong><br\/>\n   The service is designed for private connectivity patterns. You should aim for private endpoints\/private DNS and deny public access. Verify exact connectivity methods offered in your region.<\/p>\n<\/li>\n<li>\n<p><strong>Who patches the database?<\/strong><br\/>\n   It depends on the underlying database offering. Many Oracle-managed services handle patching as part of the service. Confirm responsibilities and schedules in the service documentation and your SLA.<\/p>\n<\/li>\n<li>\n<p><strong>Can I use my existing Oracle licenses (BYOL)?<\/strong><br\/>\n   Some Oracle service offerings support BYOL. Whether it applies here depends on the exact SKU and contract. Verify with Oracle pricing\/licensing documentation and your account team.<\/p>\n<\/li>\n<li>\n<p><strong>Does it support Oracle RAC \/ Data Guard?<\/strong><br\/>\n   HA\/DR features depend on the specific database service type. Do not assume RAC\/Data Guard unless explicitly listed for your offering in Oracle Database Service for Azure docs.<\/p>\n<\/li>\n<li>\n<p><strong>How does authentication work for applications?<\/strong><br\/>\n   Applications typically authenticate using Oracle Database credentials and secure connectivity methods (wallets\/TLS). Azure RBAC is for Azure resource operations, not SQL authorization.<\/p>\n<\/li>\n<li>\n<p><strong>Can I manage it with Terraform?<\/strong><br\/>\n   Azure-side resources may be manageable via ARM\/Bicep\/Terraform depending on provider support. Confirm current IaC support in official docs and the Azure resource provider documentation.<\/p>\n<\/li>\n<li>\n<p><strong>Where do I see logs for provisioning operations?<\/strong><br\/>\n   Use <strong>Azure Activity Log<\/strong> for create\/update\/delete operations. For database actions, use Oracle database audit logs.<\/p>\n<\/li>\n<li>\n<p><strong>How do I monitor performance?<\/strong><br\/>\n   Use Oracle database performance tools (views, reports) and application-side telemetry. Azure portal may provide basic health\/metrics; deeper DB performance is typically Oracle-native.<\/p>\n<\/li>\n<li>\n<p><strong>What\u2019s the biggest operational pitfall?<\/strong><br\/>\n   DNS and routing. Private connectivity requires correct private DNS configuration and ensuring the VM\/AKS nodes resolve the correct private endpoint name.<\/p>\n<\/li>\n<li>\n<p><strong>Can I access the database from on-premises?<\/strong><br\/>\n   Possibly, if your on-prem network is connected to Azure (VPN\/ExpressRoute) and routing\/DNS are configured. Confirm security and connectivity requirements.<\/p>\n<\/li>\n<li>\n<p><strong>Is the database \u201crunning in Azure\u201d or \u201crunning in Oracle Cloud\u201d?<\/strong><br\/>\n   The user experience is Azure-centric, but the database service is delivered under Oracle Cloud\u2019s managed service model. Exact physical placement and operational model are described in official Oracle\/Microsoft materials\u2014verify for your region.<\/p>\n<\/li>\n<li>\n<p><strong>Can I use Azure Key Vault for the wallet and secrets?<\/strong><br\/>\n   Yes\u2014this is a recommended best practice. Store wallet ZIPs, passwords, and connection strings as secrets, restrict access, and rotate.<\/p>\n<\/li>\n<li>\n<p><strong>How do I estimate total cost?<\/strong><br\/>\n   Combine:\n   &#8211; Oracle database service charges (compute, storage, HA\/DR)\n   &#8211; Azure network\/security\/logging costs (firewalls, Log Analytics, VM clients)\n   Use Oracle\u2019s cost estimator and Azure pricing calculator, and validate contract-based pricing via Marketplace\/private offers.<\/p>\n<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">17.

Summary<\/h2>\n\n\n\n<p>Oracle Database Service for Azure (Oracle Cloud) is a Multicloud service that enables Azure-first teams to provision and consume Oracle-managed database services through an Azure-centric experience, typically with private connectivity patterns and Azure-aligned governance.<\/p>\n\n\n\n<p>It matters because it addresses a practical enterprise need: keep the application tier on Azure while using Oracle Database capabilities without taking on the full operational load of self-managed Oracle on IaaS. Architecturally, it sits at the intersection of Azure control-plane workflows and Oracle Cloud-managed database operations\u2014so success depends on getting identity, DNS, networking, and shared responsibilities right.<\/p>\n\n\n\n<p>From a cost perspective, the biggest drivers are database compute\/storage sizing, HA\/DR choices, and indirect Azure costs such as logging and security appliances. From a security perspective, prioritize private connectivity, least privilege (Azure RBAC and database roles), and strong secrets handling (Key Vault).<\/p>\n\n\n\n<p>Use Oracle Database Service for Azure when you need Oracle Database for Azure-hosted applications and you want a managed service model; avoid it when region support, feature scope, or Multicloud operational complexity does not fit your constraints.<\/p>\n\n\n\n<p>Next step: review the official Oracle Cloud and Microsoft Azure documentation links in the resources section, confirm your region\u2019s supported offerings, and repeat the hands-on lab using your organization\u2019s standard hub\/spoke networking and governance policies.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Multicloud<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[73,62],"tags":[],"class_list":["post-937","post","type-post","status-publish","format-standard","hentry","category-multicloud","category-oracle-cloud"],"_links":{"self":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/posts\/937","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/comments?post=937"}],"version-history":[{"count":0,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/posts\/937\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/media?parent=937"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/categories?post=937"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/tags?post=937"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
