A KVM VPS lets developers configure Gunicorn, Nginx, SSL and background services without the restrictions of conventional shared hosting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Flask is commonly used for REST APIs, internal dashboards, SaaS applications, automation backends and business applications. The hosting requirement depends on whether you are deploying a small personal project or serving multiple users through a production application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The important decision is not simply choosing a server with more CPU cores. You need an appropriate combination of RAM, storage, network connectivity, operating system access and deployment tools.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>What Is the Best Hosting for Flask Applications?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The best hosting for Flask applications is generally a Linux VPS when you need root access, custom Python environments and control over production deployment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A VPS (Virtual Private Server) is a virtual machine that provides allocated computing resources and an independent operating system. KVM virtualisation allows the VPS to run its own Linux kernel, making it suitable for installing application servers, databases and system services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Flask is a Python web framework that provides tools for building web applications and APIs. It does not require a complicated hosting environment, but production deployment needs additional components to handle incoming requests, manage application processes and serve traffic securely.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why do Flask developers choose VPS hosting?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A Linux VPS provides control over the complete application environment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can install:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Python and pip for application dependencies.<\/li>\n\n\n\n<li>Virtual environments for separating project packages.<\/li>\n\n\n\n<li>Gunicorn or Waitress as a production WSGI server.<\/li>\n\n\n\n<li>Nginx as a reverse proxy.<\/li>\n\n\n\n<li>PostgreSQL or MySQL for application databases.<\/li>\n\n\n\n<li>Redis for caching and background task management.<\/li>\n\n\n\n<li>Supervisor or systemd for managing application processes.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Shared hosting generally restricts system-level configuration and long-running application processes. These restrictions can make deploying custom Flask applications difficult, particularly when the application needs background workers, non-standard dependencies or persistent services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A VPS avoids many of these restrictions by providing administrative control over the operating system. This makes it a practical choice for developers who want to manage their application stack independently.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Flask App Hosting Options Compared<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Flask app hosting can use shared hosting, managed application platforms, VPS hosting or dedicated servers depending on deployment requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The main differences involve administrative control, infrastructure responsibility and application flexibility.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Hosting type<\/strong><\/td><td><strong>Server control<\/strong><\/td><td><strong>Flask deployment<\/strong><\/td><td><strong>Suitable workload<\/strong><\/td><\/tr><tr><td>Shared hosting<\/td><td>Limited<\/td><td>Depends on provider support<\/td><td>Supported lightweight applications<\/td><\/tr><tr><td>Managed PaaS<\/td><td>Platform-controlled<\/td><td>Managed deployment<\/td><td>Developers avoiding server administration<\/td><\/tr><tr><td>KVM VPS<\/td><td>Full root access<\/td><td>Custom deployment<\/td><td>APIs, SaaS and business applications<\/td><\/tr><tr><td>Dedicated server<\/td><td>Full hardware control<\/td><td>Custom deployment<\/td><td>Large or resource-intensive applications<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">A managed PaaS can simplify deployment because the provider manages much of the underlying infrastructure. However, the available runtime, networking configuration and deployment options depend on the platform.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A VPS requires more administration, but you control the Python runtime, application processes, web server, database configuration and firewall.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a Flask application, a typical production architecture looks like this:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/xenaxcloud.com\/blog\/wp-content\/uploads\/2026\/11\/best-hosting-for-flask-1024x576.png\" alt=\"best hosting for flask\" class=\"wp-image-12214\" srcset=\"https:\/\/xenaxcloud.com\/blog\/wp-content\/uploads\/2026\/11\/best-hosting-for-flask-1024x576.png 1024w, https:\/\/xenaxcloud.com\/blog\/wp-content\/uploads\/2026\/11\/best-hosting-for-flask-300x169.png 300w, https:\/\/xenaxcloud.com\/blog\/wp-content\/uploads\/2026\/11\/best-hosting-for-flask-768x432.png 768w, https:\/\/xenaxcloud.com\/blog\/wp-content\/uploads\/2026\/11\/best-hosting-for-flask-1536x864.png 1536w, https:\/\/xenaxcloud.com\/blog\/wp-content\/uploads\/2026\/11\/best-hosting-for-flask-2048x1152.png 2048w, https:\/\/xenaxcloud.com\/blog\/wp-content\/uploads\/2026\/11\/best-hosting-for-flask-1280x720.png 1280w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nginx handles incoming HTTP and HTTPS requests and forwards them to Gunicorn, which executes the Flask application. Keeping Gunicorn bound to a private local address prevents public visitors from bypassing the reverse proxy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The VPS should also have a properly configured firewall, application logs and a process manager. These components matter because a running Python application must recover appropriately after a service restart or operating system reboot.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How Much RAM and CPU Does a Flask VPS Need?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A Flask VPS needs enough RAM and CPU for the Python application, WSGI workers, database, operating system and expected concurrent requests.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is no universal RAM requirement for Flask because the framework itself is only one component of the deployment. A small API with limited dependencies has different resource requirements from an application running database queries, background jobs and caching services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use the following configurations as initial planning guidance rather than guaranteed application requirements.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Workload<\/strong><\/td><td><strong>Suggested configuration<\/strong><\/td><td><strong>Typical use<\/strong><\/td><\/tr><tr><td>Development<\/td><td>2 vCPU, 4 GB RAM<\/td><td>Testing and small projects<\/td><\/tr><tr><td>Small production app<\/td><td>2 vCPU, 4 GB RAM<\/td><td>Lightweight Flask website or API<\/td><\/tr><tr><td>Growing application<\/td><td>2 vCPU, 8 GB RAM<\/td><td>Database and multiple application processes<\/td><\/tr><tr><td>Resource-intensive application<\/td><td>4 vCPU, 16 GB RAM or more<\/td><td>Larger workloads and background processing<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>CPU requirements<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">CPU capacity affects how quickly application processes execute Python code and handle requests.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, an API performing basic database lookups may need less CPU than an application performing image processing, report generation or computational tasks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gunicorn uses worker processes to handle application requests. Adding workers can increase concurrency, but each worker also consumes memory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Do not increase the worker count without monitoring RAM and CPU consumption.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>RAM requirements<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">RAM is shared by the operating system, Python processes, application dependencies, database services and caching systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A common mistake is allocating all available memory to Gunicorn workers. The operating system and other services also need memory, so leave sufficient headroom for normal operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Monitor memory utilisation during peak traffic instead of choosing a configuration based only on the number of application routes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Storage requirements<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Storage capacity should account for application files, dependencies, logs, database records, uploaded documents and backup requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">NVMe storage is useful for applications performing frequent database reads and writes. However, faster storage cannot compensate for insufficient RAM or poorly optimised database queries.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Xenax Cloud Speed VPS uses NVMe storage, while General VPS provides more RAM per vCPU for memory-intensive workloads.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How to Deploy Flask on VPS Using Gunicorn and Nginx<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You can deploy Flask on VPS by creating a Python virtual environment, installing application dependencies, configuring Gunicorn and placing Nginx in front of the application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The following example uses Ubuntu, a Flask application named app.py and a Linux VPS with root access.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 1: Connect to your VPS<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Connect to your Linux VPS through SSH:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ssh root@YOUR_SERVER_IP<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Update the operating system packages:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">apt update &amp;&amp; apt upgrade -y<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Install Python, pip, virtual environment tools and Nginx:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">apt install python3 python3-pip python3-venv nginx -y<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 2: Create the Flask project<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Create an application directory:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">mkdir -p \/srv\/flaskapp<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">cd \/srv\/flaskapp<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Create a virtual environment:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">python3 -m venv .venv<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Activate it:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">source .venv\/bin\/activate<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Install Flask and Gunicorn:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">pip install flask gunicorn<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Create a basic application:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">from flask import Flask<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">app = Flask(__name__)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">@app.route(&#8220;\/&#8221;)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">def home():<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&nbsp;&nbsp;&nbsp;&nbsp;return &#8220;Flask application is running&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Save the file as app.py.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Step 3: Test Gunicorn<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Run the following command:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">gunicorn &#8211;workers 2 &#8211;bind 127.0.0.1:8000 app:app<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Open another SSH session and check the local application:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">curl http:\/\/127.0.0.1:8000<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You should receive:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Flask application is running<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The example uses two Gunicorn workers for demonstration.

Two application worker processes handle incoming requests, while background tasks perform scheduled processing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For this illustrative workload, a General VPS with 2 vCPU and 8 GB RAM is a reasonable starting configuration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Why choose General VPS instead of a smaller 2 vCPU and 4 GB RAM configuration?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The deciding factor is memory headroom. The Flask application, PostgreSQL, Redis, Gunicorn workers and Linux operating system all compete for available RAM. Additional memory provides more room for these services without immediately increasing CPU allocation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A Speed VPS with 2 vCPU and 4 GB RAM may be more suitable if the application is lightweight and storage responsiveness is the priority. However, the smaller memory configuration is less suitable for this combined application and database workload.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The developer should monitor application response times, database activity, RAM utilisation and CPU usage after deployment. If background processing becomes CPU-intensive, a configuration with more vCPU may be necessary.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Which Xenax Cloud VPS Is Suitable for Flask Hosting?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Xenax Cloud offers three KVM VPS families for Linux application hosting: Speed VPS, General VPS and Gold VPS.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">All three VPS families provide full root access, one IPv4 address, a 500 Mbps network port and weekly backups.

Review actual server utilisation before upgrading.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A common mistake is assuming that a Flask application needs a large server simply because it is a production application. A small API with limited traffic may operate comfortably on a smaller VPS, while an inefficient application with expensive database queries can consume substantial resources even with fewer users.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another mistake is running Flask using its built-in development server in production. The Flask documentation explicitly advises using a production WSGI server instead because the development server is not designed for production security, stability or efficiency.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Is VPS Hosting Secure for Flask Applications?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">VPS hosting can provide a secure environment for Flask applications when the operating system, application and network services are configured correctly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A VPS gives you control over security settings, but it also makes you responsible for maintaining the server.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Follow these practices:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Use non-root application accounts.<\/strong> Run Gunicorn and Flask under a dedicated Linux user.<\/li>\n\n\n\n<li><strong>Protect SSH access.<\/strong> Use SSH keys and restrict administrative access.<\/li>\n\n\n\n<li><strong>Configure a firewall.<\/strong> Expose only the ports required for public application traffic.<\/li>\n\n\n\n<li><strong>Enable HTTPS.<\/strong> Use a valid TLS certificate for encrypted browser connections.<\/li>\n\n\n\n<li><strong>Protect application secrets.<\/strong> Store database passwords and Flask secret keys outside publicly accessible source files.<\/li>\n\n\n\n<li><strong>Update dependencies.<\/strong> Keep Python packages, operating system components and application libraries maintained.<\/li>\n\n\n\n<li><strong>Maintain backups.<\/strong> Back up database records, uploaded files and application configuration separately.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Flask&#8217;s SECRET_KEY should be generated securely and should not be committed to a public Git repository. Database credentials should also be stored using protected environment variables or an appropriate secrets management method.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Xenax Cloud provides weekly VPS backups, but you should maintain application-level database backups and test restoration independently.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A VPS is not the right choice if you do not want to manage Linux updates, application deployment, database maintenance and security configuration. In that situation, a managed application hosting platform may be more appropriate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For additional deployment and server management information, consult the <a target=\"_blank\" href=\"https:\/\/flask.palletsprojects.com\/en\/stable\/deploying\/\" rel=\"noopener\">official Flask production deployment documentation<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Best Hosting for Flask: FAQs<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Can I host a Flask application on a VPS?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, you can host a Flask application on a Linux VPS with Python, a virtual environment and a production WSGI server. A KVM VPS provides root access for installing Gunicorn, Nginx and database services. You also control firewall rules, application processes and deployment configurations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Is shared hosting suitable for Flask applications?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Shared hosting is suitable only when the provider explicitly supports your Flask runtime and application requirements. Many shared environments restrict persistent Python processes, custom packages and server-level configuration. A VPS is generally more appropriate when you need Gunicorn, background workers or custom database services.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Is Gunicorn required for Flask production hosting?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Gunicorn is not the only production server available, but it is a common choice for Linux-based Flask deployments. It runs Flask through the WSGI interface and manages application worker processes. You can also evaluate Waitress or other supported production WSGI servers according to your application requirements.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How much RAM does a Flask application need?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A lightweight Flask application can start with 4 GB RAM on a VPS, depending on its dependencies and workload. Applications running PostgreSQL, Redis and multiple Gunicorn workers may need 8 GB RAM or more. Monitor actual memory consumption before selecting or upgrading your configuration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Can I run multiple Flask applications on one VPS?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, you can run multiple Flask applications on one VPS using separate Python virtual environments, systemd services and Nginx server blocks. Each application should have its own process configuration and domain mapping. Ensure the combined applications have sufficient RAM, CPU, storage and database capacity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Is Flask better than Django for VPS hosting?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Flask is a lightweight framework that gives developers flexibility over application components, while Django includes more built-in features such as an ORM, authentication and administration tools. Flask can suit smaller APIs and custom services, whereas Django may suit applications needing its integrated framework features.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Which Xenax Cloud VPS is best for Flask?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">General VPS is a suitable starting choice for Flask applications that need additional RAM per vCPU. Speed VPS is appropriate when NVMe storage responsiveness matters, while Gold VPS suits processing-intensive applications. Choose the configuration according to your database, worker count and actual application resource usage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a new Flask deployment, start with Speed VPS at 2 vCPU, 4 GB RAM and 40 GB storage for a lightweight application, or General VPS at 2 vCPU and 8 GB RAM for a memory-intensive application. Select a larger configuration when measured CPU, RAM or storage requirements justify it.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Flask is a lightweight Python web framework, and the best hosting for Flask is usually a Linux VPS that provides control over Python, application dependencies, databases\u2026<\/p>\n","protected":false},"author":4,"featured_media":12215,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","rank_math_title":"Best Hosting for Flask | Linux VPS Deployment","rank_math_description":"Find the best hosting for Flask applications, compare Linux VPS resources and learn to deploy Python apps using Gunicorn, Nginx and production-ready settings.\n","rank_math_focus_keyword":"best hosting for flask , flask app hosting , deploy flask on vps","rank_math_canonical_url":"","rank_math_facebook_image":"","rank_math_facebook_image_id":0,"xseo_schema_type":"","xseo_sitemap_exclude":false,"rank_math_robots":[],"_xseo_takeaways":["Flask applications need a production WSGI server instead of Flask's built-in development server.","Gunicorn runs Flask applications behind Nginx on a Linux VPS.","A KVM VPS provides root access for installing Python, databases and application dependencies.","Speed VPS offers NVMe storage, while General VPS provides more RAM per vCPU.","Xenax Cloud VPS includes a 500 Mbps network port, one IPv4 address and weekly backups."]},"categories":[15],"tags":[],"class_list":["post-12213","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-hosting"],"_links":{"self":[{"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/posts\/12213","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/comments?post=12213"}],"version-history":[{"count":4,"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/posts\/12213\/revisions"}],"predecessor-version":[{"id":12219,"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/posts\/12213\/revisions\/12219"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/media\/12215"}],"wp:attachment":[{"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/media?parent=12213"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/categories?post=12213"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/xenaxcloud.com\/blog\/wp-json\/wp\/v2\/tags?post=12213"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
