Introduction<\/h2>\n\n\n\n<p>AWS Elemental MediaTailor is an AWS Media service for <strong>server-side ad insertion (SSAI)<\/strong> and <strong>manifest manipulation<\/strong> for video streaming. It helps you monetize live and video-on-demand (VOD) streams by inserting ads server-side so viewers receive a single continuous stream, typically improving ad-block resistance and playback reliability compared to client-side ad insertion.<\/p>\n\n\n\n<p>In simple terms: <strong>your player requests a playlist\/manifest from AWS Elemental MediaTailor<\/strong>, and MediaTailor returns a <strong>personalized<\/strong> manifest that includes ad segments (or ad decision instructions) so the viewer sees ads at the right moments\u2014without the player having to stitch ads itself.<\/p>\n\n\n\n<p>Technically, AWS Elemental MediaTailor sits on the <strong>manifest path<\/strong> for HLS and DASH workflows. It receives a manifest request, creates a <strong>session<\/strong>, calls your <strong>ad decision server (ADS)<\/strong> (for example via VAST\/VMAP, depending on your integration), selects ad creatives, and then <strong>returns a rewritten manifest<\/strong> that points to ad segments (and\/or content segments) so the playback device can fetch a seamless sequence.<\/p>\n\n\n\n<p><strong>What problem it solves:<\/strong> monetizing streaming video reliably at scale\u2014especially for OTT apps\u2014by performing ad insertion server-side, integrating with industry ad decisioning, and reducing complexity in player apps.<\/p>\n\n\n\n<blockquote>\n<p>Service name note: <strong>AWS Elemental MediaTailor<\/strong> is the current official name as used by AWS. If you see older references to \u201cMediaTailor\u201d without the \u201cAWS Elemental\u201d prefix, they typically refer to the same service branding.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">2. What is AWS Elemental MediaTailor?<\/h2>\n\n\n\n<p>AWS Elemental MediaTailor is a managed service designed to enable <strong>SSAI and manifest-level personalization<\/strong> for streaming video. It is primarily used to insert ads into <strong>HLS<\/strong> and <strong>DASH<\/strong> streams for <strong>live<\/strong> and <strong>VOD<\/strong> workflows.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Official purpose (high-level)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Enable server-side ad insertion for streaming video.<\/li>\n<li>Personalize manifests per viewer\/session.<\/li>\n<li>Integrate streaming workflows with ad decisioning systems.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Core capabilities<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Server-side ad insertion (SSAI):<\/strong> Inserts ads by manipulating manifests so players request ad media segments like normal content segments.<\/li>\n<li><strong>Session-based playback:<\/strong> Generates per-request\/per-session manifests that can vary by viewer context (depending on your integration).<\/li>\n<li><strong>Integration with ad decision servers (ADS):<\/strong> Requests ads and uses returned ad creatives for stitching (exact protocol and requirements depend on your ADS and MediaTailor configuration\u2014verify specifics in official docs for your target ADS).<\/li>\n<li><strong>Works with HLS and DASH:<\/strong> Commonly used for OTT playback.<\/li>\n<li><strong>Live and VOD support:<\/strong> Live insertion typically relies on cue markers (for example SCTE-35 in many broadcast-to-OTT workflows).

Top Use Cases and Scenarios<\/h2>\n\n\n\n<p>Below are realistic scenarios where AWS Elemental MediaTailor is commonly used.<\/p>\n\n\n\n<p>1) <strong>Live sports SSAI with SCTE-35 ad avails<\/strong>\n&#8211; <strong>Problem:<\/strong> Live sports streams must insert ads at precisely timed breaks without buffering.\n&#8211; <strong>Why MediaTailor fits:<\/strong> It can use live ad avail markers (commonly SCTE-35 based in many workflows) to stitch ads server-side.\n&#8211; <strong>Example:<\/strong> A sports app inserts regional ads during timeouts while streaming HLS via CloudFront.<\/p>\n\n\n\n<p>2) <strong>FAST channel monetization<\/strong>\n&#8211; <strong>Problem:<\/strong> A linear 24\/7 channel needs consistent ad breaks and measurable ad delivery.\n&#8211; <strong>Why it fits:<\/strong> SSAI can deliver a broadcast-like experience and simplify device support across smart TVs.\n&#8211; <strong>Example:<\/strong> A FAST startup delivers an always-on channel, monetized by SSAI ads.<\/p>\n\n\n\n<p>3) <strong>VOD library with mid-roll ads<\/strong>\n&#8211; <strong>Problem:<\/strong> VOD content needs pre-roll and mid-roll insertion without building complex player logic.\n&#8211; <strong>Why it fits:<\/strong> MediaTailor can return personalized manifests that include ad segments.\n&#8211; <strong>Example:<\/strong> A catch-up TV service inserts mid-roll ads at chapter boundaries.<\/p>\n\n\n\n<p>4) <strong>Reduced ad-blocking impact<\/strong>\n&#8211; <strong>Problem:<\/strong> Client-side ads are more likely to be blocked or skipped with ad blockers and network filters.\n&#8211; <strong>Why it fits:<\/strong> SSAI blends ads into the same stream workflow (manifest\/segments).\n&#8211; <strong>Example:<\/strong> A web player receives a single stitched playlist; ad blockers have less visibility into separate ad calls.<\/p>\n\n\n\n<p>5) <strong>Simplified multi-device playback<\/strong>\n&#8211; <strong>Problem:<\/strong> Maintaining CSAI logic across iOS, Android, web, Roku, Fire TV, smart TVs is expensive.\n&#8211; <strong>Why it fits:<\/strong> SSAI reduces per-device ad logic; devices just play HLS\/DASH.\n&#8211; <strong>Example:<\/strong> A broadcaster supports older TV platforms by relying on SSAI rather than complex client SDKs.<\/p>\n\n\n\n<p>6) <strong>Ad decision server integration for targeted advertising<\/strong>\n&#8211; <strong>Problem:<\/strong> Ads must be chosen dynamically based on region\/device\/user segment.\n&#8211; <strong>Why it fits:<\/strong> MediaTailor integrates with an ADS; targeting happens in the ad decision layer.\n&#8211; <strong>Example:<\/strong> The ADS returns different creatives for different countries; MediaTailor stitches accordingly.<\/p>\n\n\n\n<p>7) <strong>Peak-event scaling (e.g., election night, season finale)<\/strong>\n&#8211; <strong>Problem:<\/strong> Manifest requests spike dramatically; ad insertion must remain stable.\n&#8211; <strong>Why it fits:<\/strong> Managed service + CDN patterns can absorb spikes better than self-managed infrastructure.\n&#8211; <strong>Example:<\/strong> A news organization experiences 10x traffic during breaking events.<\/p>\n\n\n\n<p>8) <strong>Centralized ad policy enforcement<\/strong>\n&#8211; <strong>Problem:<\/strong> Teams need consistent rules for ad fill, slates, and fallback across many channels.\n&#8211; <strong>Why it fits:<\/strong> Playback configurations centralize behavior.\n&#8211; <strong>Example:<\/strong> A platform enforces \u201cslate on no-fill\u201d across all apps to avoid blank screens.<\/p>\n\n\n\n<p>9) <strong>Phased migration from CSAI to SSAI<\/strong>\n&#8211; <strong>Problem:<\/strong> You want to move to SSAI without rewriting the entire pipeline at once.\n&#8211; <strong>Why it fits:<\/strong> MediaTailor can sit in front of existing origins while you gradually adopt AWS Media services.\n&#8211; <strong>Example:<\/strong> Start with one channel in SSAI for specific device families and expand.<\/p>\n\n\n\n<p>10) <strong>Ad measurement and operational visibility<\/strong>\n&#8211; <strong>Problem:<\/strong> You need visibility into ad requests, fill rates, and error rates at scale.\n&#8211; <strong>Why it fits:<\/strong> MediaTailor provides metrics (and supports integration patterns for logging\/monitoring; verify your exact reporting needs in official docs).\n&#8211; <strong>Example:<\/strong> SRE dashboards alert on increased ad decision timeouts during prime time.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6. Core Features<\/h2>\n\n\n\n<p>This section focuses on key AWS Elemental MediaTailor features and what to watch out for.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6.1 Server-Side Ad Insertion (SSAI)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it does:<\/strong> Rewrites manifests to include ads as part of the streaming timeline.<\/li>\n<li><strong>Why it matters:<\/strong> Reduces player complexity and can improve playback continuity.<\/li>\n<li><strong>Practical benefit:<\/strong> One playback session produces a viewer-ready manifest; players fetch segments normally.<\/li>\n<li><strong>Limitations\/caveats:<\/strong> SSAI depends on correct cueing (live) or correct VOD markers. Ad creative compatibility (codec, resolution, segmenting) must match your streaming profile\u2014otherwise playback issues can occur.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6.2 Session-based manifest personalization<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it does:<\/strong> Generates manifests per request\/session so ad selection can differ per viewer.<\/li>\n<li><strong>Why it matters:<\/strong> Enables targeted ads and dynamic decisions.<\/li>\n<li><strong>Practical benefit:<\/strong> You can integrate with an ADS that returns different creatives based on parameters.<\/li>\n<li><strong>Limitations\/caveats:<\/strong> Personalization increases manifest variability which can reduce CDN cache hit ratio if not designed carefully.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6.3 Ad decision server (ADS) integration<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it does:<\/strong> Calls an ADS to retrieve ads for an avail\/break.<\/li>\n<li><strong>Why it matters:<\/strong> Your monetization logic typically lives in ad-tech platforms.<\/li>\n<li><strong>Practical benefit:<\/strong> Connect your streaming pipeline to existing ad sales and targeting.<\/li>\n<li><strong>Limitations\/caveats:<\/strong> ADS latency and reliability directly affect playback. You need timeouts, fallbacks (slates), and realistic SLA planning.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6.4 Live ad insertion with cue markers (commonly SCTE-35-based workflows)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it does:<\/strong> Uses ad avail signaling to know when to insert ads into live streams.<\/li>\n<li><strong>Why it matters:<\/strong> Live streams require precise insertion without disrupting the event.<\/li>\n<li><strong>Practical benefit:<\/strong> Broadcast-style ad breaks can be translated to OTT delivery.<\/li>\n<li><strong>Limitations\/caveats:<\/strong> Cue signaling must be preserved end-to-end (encoder \u2192 packager \u2192 MediaTailor). Misconfigured SCTE-35 handling is a common failure mode.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6.5 VOD ad insertion<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it does:<\/strong> Inserts ads into VOD streams at defined insertion points.<\/li>\n<li><strong>Why it matters:<\/strong> VOD is a major monetization surface for catch-up and episodic content.<\/li>\n<li><strong>Practical benefit:<\/strong> Monetize content libraries without client-side ad SDK dependence.<\/li>\n<li><strong>Limitations\/caveats:<\/strong> VOD cue point strategy differs by packager\/origin. Always test with your packaging format and player.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6.6 Fallback behavior (e.g., slates)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it does:<\/strong> Plays alternative filler content when ads are not available (no-fill) or when errors occur, depending on configuration.<\/li>\n<li><strong>Why it matters:<\/strong> Avoids dead air\/black screens during breaks.<\/li>\n<li><strong>Practical benefit:<\/strong> Viewers see a consistent experience even when ad inventory is unavailable.<\/li>\n<li><strong>Limitations\/caveats:<\/strong> Slate content must be encoded\/packaged compatibly with your stream variants.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6.7 CDN-friendly origin pattern (commonly CloudFront in front)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it does:<\/strong> Works well behind a CDN that caches and accelerates delivery.<\/li>\n<li><strong>Why it matters:<\/strong> Manifest traffic is high-frequency.<\/li>\n<li><strong>Practical benefit:<\/strong> Reduced latency and better global performance.<\/li>\n<li><strong>Limitations\/caveats:<\/strong> Over-caching personalized manifests can serve the wrong content to the wrong viewers if caching is not configured carefully (cache key, TTLs, query strings, headers).<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6.8 Metrics and operational visibility (CloudWatch integration patterns)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it does:<\/strong> Provides service metrics that help you understand request volume, errors, and ad-related performance indicators.<\/li>\n<li><strong>Why it matters:<\/strong> SSAI problems show up as playback failures and revenue impact.<\/li>\n<li><strong>Practical benefit:<\/strong> Alerting on fill rate, ad decision errors, and manifest errors reduces MTTR.<\/li>\n<li><strong>Limitations\/caveats:<\/strong> Exact metric names and available dimensions can change; verify in the official user guide and CloudWatch console for your Region.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">6.9 Compatibility with AWS Media services (MediaPackage, MediaLive, MediaConvert)<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>What it does:<\/strong> Fits into AWS\u2019s reference architectures for live and VOD.<\/li>\n<li><strong>Why it matters:<\/strong> Many teams want a cohesive AWS-native pipeline.<\/li>\n<li><strong>Practical benefit:<\/strong> Standard patterns exist for MediaLive\u2192MediaPackage\u2192MediaTailor.<\/li>\n<li><strong>Limitations\/caveats:<\/strong> MediaTailor does not replace encoding (MediaLive) or transcoding (MediaConvert). It relies on a correctly packaged origin.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">7. Architecture and How It Works<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">High-level architecture<\/h3>\n\n\n\n<p>At a high level:\n1. A viewer\u2019s device requests a playback manifest (HLS master\/media playlist or DASH MPD).\n2. The request goes (often) through a CDN (CloudFront).\n3. MediaTailor receives the request and creates\/maintains a <strong>session<\/strong>.\n4. MediaTailor fetches the origin manifest from your <strong>content origin<\/strong> (often MediaPackage or another origin).\n5. When an ad break is reached, MediaTailor calls the <strong>ad decision server (ADS)<\/strong>.\n6.

The console usually shows a <strong>Playback URL<\/strong> or <strong>Session initialization prefix<\/strong>.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>In the playback configuration details, find the <strong>Playback endpoint \/ Manifest URL<\/strong> pattern.<\/li>\n<li>Copy the <strong>HLS playback URL<\/strong> (or session URL).<\/li>\n<li>Fetch it with <code>curl<\/code>:\n   <code>bash\n   curl -sS \"https:\/\/MEDIATAILOR-PLAYBACK-URL\" | head -n 60<\/code><\/li>\n<\/ol>\n\n\n\n<p>Expected outcome:\n&#8211; You receive an HLS playlist response (text that starts with <code>#EXTM3U<\/code>).\n&#8211; The manifest may contain MediaTailor-specific tags and\/or ad-related discontinuities depending on your content markers and ADS response.<\/p>\n\n\n\n<p>Verification checks (what to look for):\n&#8211; Confirm it\u2019s an HLS playlist:\n  &#8211; First line should be <code>#EXTM3U<\/code>\n&#8211; Look for signs of rewriting:\n  &#8211; Additional tags\n  &#8211; References to ad segment URLs or different base URLs\n  &#8211; Discontinuities around ad breaks (<code>#EXT-X-DISCONTINUITY<\/code> is common in stitched playlists)<\/p>\n\n\n\n<p>Notes:\n&#8211; If your content has <strong>no ad markers\/cue points<\/strong>, MediaTailor may return content without inserting mid-roll ads. Some workflows require explicit cue markers or configuration to define break behavior\u2014<strong>verify the correct method for your content\/origin in the official docs<\/strong>.\n&#8211; If the ADS returns <strong>no fill<\/strong>, you may not see ads unless you configured a slate.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: (Optional) Try playback in a local test player<\/h3>\n\n\n\n<p>To confirm end-to-end behavior you can test in:\n&#8211; A local HLS-capable player\n&#8211; A browser-based test player (if you already have one in your environment)<\/p>\n\n\n\n<p>Because player setup varies widely and can introduce DRM\/CORS complications, keep this optional for the lab. The core learning goal is understanding how MediaTailor changes the manifest.<\/p>\n\n\n\n<p>Expected outcome:\n&#8211; If the stream is compatible, you see content playback and (if ad breaks are properly cued and filled) ads.<\/p>\n\n\n\n<p>Common errors and fixes:\n&#8211; <strong>CORS issues in browsers<\/strong>: Typically solved with CloudFront configuration and correct headers (for production).\n&#8211; <strong>Codec mismatch<\/strong>: Ads must match content ladder expectations.

FAQ<\/h2>\n\n\n\n<p>1) <strong>What is AWS Elemental MediaTailor used for?<\/strong><br\/>\nIt\u2019s used for server-side ad insertion (SSAI) and manifest manipulation for streaming video, primarily HLS and DASH.<\/p>\n\n\n\n<p>2) <strong>Does MediaTailor transcode video?<\/strong><br\/>\nNo. Transcoding is handled by services like AWS Elemental MediaLive (live) or AWS Elemental MediaConvert (VOD). MediaTailor focuses on manifests and ad stitching logic.<\/p>\n\n\n\n<p>3) <strong>Can I use MediaTailor with origins other than AWS Elemental MediaPackage?<\/strong><br\/>\nOften yes, as long as the origin provides compatible HLS\/DASH manifests and segments over HTTP(S). Validate your origin\u2019s compatibility in a proof-of-concept.<\/p>\n\n\n\n<p>4) <strong>Is MediaTailor global?<\/strong><br\/>\nMediaTailor is typically a <strong>regional<\/strong> AWS service. Use CloudFront for global edge delivery.<\/p>\n\n\n\n<p>5) <strong>How does MediaTailor handle live ad breaks?<\/strong><br\/>\nCommonly via ad avail markers (often SCTE-35-based workflows) carried through the live pipeline. Exact requirements depend on your encoder\/packager.<\/p>\n\n\n\n<p>6) <strong>Do I need CloudFront in front of MediaTailor?<\/strong><br\/>\nNot strictly required, but strongly recommended for performance, scale, and security controls (WAF, signed URLs\/cookies).<\/p>\n\n\n\n<p>7) <strong>How do I prevent users from sharing playback URLs?<\/strong><br\/>\nUse CloudFront signed URLs\/cookies and tokenization patterns. Avoid putting secrets directly into URLs.<\/p>\n\n\n\n<p>8) <strong>Why are my ads not playing?<\/strong><br\/>\nCommon causes: missing cue markers, ADS no-fill, ad creatives incompatible with your content ladder, or caching misconfiguration. Start by inspecting the returned manifest.<\/p>\n\n\n\n<p>9) <strong>Does SSAI eliminate ad blockers completely?<\/strong><br\/>\nNo solution eliminates all blocking, but SSAI generally reduces simple client-side ad-blocking because ads appear as part of the stream.<\/p>\n\n\n\n<p>10) <strong>Can MediaTailor insert different ads for different users?<\/strong><br\/>\nYes, through session-based manifest personalization and ADS targeting.<\/p>\n\n\n\n<p>11) <strong>How do I monitor MediaTailor health?<\/strong><br\/>\nUse CloudWatch metrics and CloudFront metrics\/logs. Add alarms for error rates and ad decision failures. Verify specific metric names in your Region.<\/p>\n\n\n\n<p>12) <strong>What happens if the ad decision server is slow or down?<\/strong><br\/>\nDepending on configuration, MediaTailor may fall back (for example, slates) or the user may experience playback issues during breaks. Design for ADS resilience.<\/p>\n\n\n\n<p>13) <strong>Does MediaTailor support DRM?<\/strong><br\/>\nDRM is typically enforced by your packager\/origin and player. MediaTailor operates at the manifest level; DRM compatibility must be tested in your end-to-end workflow.<\/p>\n\n\n\n<p>14) <strong>Can I use MediaTailor for both live and VOD?<\/strong><br\/>\nYes, it supports both, but cueing methods and operational considerations differ.<\/p>\n\n\n\n<p>15) <strong>What\u2019s the easiest way to start learning MediaTailor?<\/strong><br\/>\nCreate a small VOD configuration with public test content and a test ad tag, then inspect how manifests change. Next, integrate with a real origin and ADS in a staging environment.<\/p>\n\n\n\n<p>16) <strong>How do I keep costs under control?<\/strong><br\/>\nProtect endpoints with WAF and rate limiting, tune caching, and model manifest request rates. Monitor for bot traffic.<\/p>\n\n\n\n<p>17) <strong>Is MediaTailor suitable for enterprise-scale OTT?<\/strong><br\/>\nYes, it\u2019s used in enterprise OTT architectures, but you must design the full pipeline (origin, CDN, ADS, monitoring) correctly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">17.

Summary<\/h2>\n\n\n\n<p>AWS Elemental MediaTailor is AWS\u2019s managed <strong>Media<\/strong> service for <strong>server-side ad insertion (SSAI)<\/strong> and session-based manifest personalization for <strong>HLS and DASH<\/strong> streaming. It matters because SSAI is operationally difficult to build correctly at scale, and MediaTailor provides a managed way to integrate streaming origins with ad decision servers while simplifying player applications.<\/p>\n\n\n\n<p>From an architecture perspective, MediaTailor sits between your <strong>CDN\/player<\/strong> and your <strong>origin<\/strong>, and it depends heavily on correct cue markers, ad creative compatibility, and robust upstream systems (origin + ADS). Cost is driven by manifest\/session activity, ad delivery, and\u2014indirectly\u2014CDN and bandwidth usage; security is largely about controlling public playback endpoints with CloudFront, WAF, and careful caching.<\/p>\n\n\n\n<p>Use AWS Elemental MediaTailor when you need managed SSAI for OTT monetization on AWS. Next learning step: build a staging pipeline (MediaLive \u2192 MediaPackage \u2192 MediaTailor \u2192 CloudFront) and validate ad insertion behavior, caching strategy, monitoring, and security controls end-to-end using the official documentation at https:\/\/docs.aws.amazon.com\/mediatailor\/.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Media<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[20,34],"tags":[],"class_list":["post-282","post","type-post","status-publish","format-standard","hentry","category-aws","category-media"],"_links":{"self":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/posts\/282","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=282"}],"version-history":[{"count":0,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/posts\/282\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/media?parent=282"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/categories?post=282"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.devopsschool.com\/tutorials\/wp-json\/wp\/v2\/tags?post=282"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
