Apache CloudStack vs Temporal

Apache CloudStack is free, open-source software for deploying and managing networks of virtual machines as a highly available, scalable IaaS cloud platform. Organizations can use it to build public, private, or hybrid clouds. Its features include compute orchestration, network services, account management, resource accounting, a web interface, and an open API. Operators can manage clouds through a web UI, command-line tools, or REST API, with optional AWS EC2- and S3-compatible APIs. Supported hypervisors include XenServer or XCP, KVM, Hyper-V, and VMware ESXi with vSphere. Storage options include iSCSI, NFS, Ceph RBD with KVM, volume encryption, snapshots, and storage tiering. Authentication options include OAuth2 single sign-on, two-factor authentication, TOTP, SAML, and LDAP. The project says CloudStack can manage tens of thousands of physical servers across geographically distributed data centers. Long Term Support releases receive bug and security fixes for 18 months after the main release. Operators remain responsible for protections such as monitoring, host security, and defenses against DoS and brute-force attacks.

Temporal is a workflow platform for applications that need work to recover after crashes, network failures, or infrastructure outages. Workflows preserve state at each step and resume from that point. Failure-handling tools include automatic retries with backoff, timeout classes, heartbeating, and Saga compensation. Durable timers can wait for months; cron schedules support backfill, and workflows can use Continue-As-New. Signals, Queries, Updates, and Workflow Streams let users read or change workflows while they run. Teams can self-host the open-source Temporal Service or use managed Temporal Cloud. SDKs are listed for Go, Java, Python, TypeScript,.NET, PHP, Ruby, and Rust, alongside integrations for several AI tools. Temporal Cloud keeps application code and data in customer-controlled infrastructure, sending encrypted orchestration data to the service; it uses AES 256 encryption at rest and TLS in transit. The cloud service is SOC 2 Type II certified and compliant with GDPR and HIPAA. Pay-As-You-Go has no base monthly fee and includes $150 in credits for 90 days; Business costs $500 a month or 10% of usage, whichever is greater.
