Platform
Four core products that work seamlessly together. Each one is best-in-class on its own — together they give you a complete, vertically integrated cloud platform.
High-performance virtual machines, bare-metal servers, and container runtimes powered by the latest AMD EPYC and Intel Xeon processors. Spin up instances in under 10 seconds with dedicated vCPU, NVMe storage, and up to 100 Gbps networking.
S3-compatible object storage, high-IOPS block volumes, and a globally distributed file system. Store petabytes of data with 11 nines of durability, automatic replication across regions, and instant CDN integration for fast access worldwide.
Fully managed PostgreSQL, MySQL, Redis, and MongoDB with automated backups, read replicas, and connection pooling. Scale from a hobby project to millions of queries per second without changing a line of code or worrying about maintenance windows.
A global anycast network spanning 30+ regions with built-in load balancing, DDoS mitigation, and private networking. Route traffic intelligently with our edge network, secure services with managed TLS, and connect VPCs across regions with encrypted tunnels.
Features
Every feature you need to run production workloads at scale, built into the platform from day one.
Automatically scale from zero to thousands of instances based on CPU, memory, request count, or custom metrics. Set policies once and let the platform handle traffic spikes and quiet periods efficiently.
Serve static and dynamic content from 200+ edge locations worldwide. Intelligent caching, Brotli compression, and HTTP/3 support ensure your users get sub-50ms response times wherever they are on the planet.
Enterprise-grade Layer 3/4/7 DDoS mitigation included at no extra cost. Our globally distributed scrubbing centers absorb up to 10 Tbps of attack traffic while legitimate requests flow through uninterrupted.
Push to deploy with built-in continuous integration and delivery. Connect your GitHub, GitLab, or Bitbucket repo, define your pipeline in YAML, and get automatic builds, tests, and zero-downtime rolling deployments.
Private Docker container registry with vulnerability scanning, image signing, and geo-replicated storage. Pull images at wire speed from the nearest region with our distributed registry architecture.
Run code without provisioning servers. Support for Node.js, Python, Go, Rust, and more. Cold starts under 50ms with our V8 isolate runtime. Scale to millions of invocations with pay-per-execution pricing.
Production-ready Kubernetes clusters in minutes. We manage the control plane, etcd, upgrades, and security patches. You focus on deploying workloads. Integrated with our load balancers, storage, and monitoring.
Global and regional load balancers with health checks, sticky sessions, and weighted routing. Support for HTTP/2, gRPC, WebSocket, and TCP. Distribute traffic intelligently across instances, regions, and availability zones.
Real-time metrics, distributed tracing, and centralized logging built into every service. Set up alerts via email, Slack, PagerDuty, or webhooks. Custom dashboards with 15-second granularity and 13 months of retention.
Developer Experience
Everything you can do in the dashboard, you can do from the command line or through our API. First-class SDKs for JavaScript, Python, Go, Ruby, and Rust. Infrastructure as code with Terraform and Pulumi providers.
Deploy, scale, and manage infrastructure with intuitive commands. Tab completion, interactive prompts, and JSON output for scripting.
Fully documented OpenAPI 3.0 spec. Type-safe SDKs auto-generated from the spec ensure you always have the latest endpoints.
Terraform provider and Pulumi SDK for managing infrastructure declaratively. Version-controlled, reviewable, and repeatable deployments.

Testimonials
Hear from the developers and CTOs who build on CloudStack every day.
"We migrated from AWS to CloudStack in a weekend. Our infra costs dropped 40% and deploy times went from 12 minutes to under 30 seconds. The developer experience is genuinely a generation ahead."
"The managed Kubernetes offering is the best I've used. We went from spending 2 days a week on cluster maintenance to zero. The integrated monitoring and auto-scaling just work out of the box."
"CloudStack's serverless functions have cold starts under 50ms. We moved our entire event-driven architecture here and our p99 latency dropped by 3x compared to Lambda. The DX is phenomenal."
"As a startup, we needed to move fast without compromising on security. CloudStack gave us SOC 2 compliance out of the box and the pricing is transparent. No more surprise AWS bills at month end."
"We run 200+ microservices on CloudStack's managed Kubernetes. The observability stack (metrics, logs, traces) being built-in saved us from maintaining a separate Datadog/Grafana setup. Incredible platform."
"The CLI is genuinely a joy to use. Autocomplete, interactive mode, and the ability to pipe JSON output to jq makes scripting a breeze. I've automated our entire staging environment provisioning in a single bash script."

FAQ
From the Blog
A deep dive into our serverless runtime architecture. We explain how we use V8 isolates instead of containers to achieve cold starts that are 10x faster than traditional FaaS platforms, while maintaining full Node.js compatibility.
How our managed PostgreSQL achieves automatic failover in under 30 seconds using a combination of synchronous replication, consensus-based leader election, and intelligent connection routing at the proxy layer.
A look inside our globally distributed scrubbing infrastructure. We detail how we use eBPF, XDP, and custom FPGA-based packet processing to absorb massive volumetric attacks while keeping legitimate traffic flowing with zero added latency.
