Apache CloudStack vs DNSimple: at a glance
What is Apache CloudStack?
Apache CloudStack 4.23 ships as a Regular release while two LTS branches stay on maintenance cadence.
Apache CloudStack maintains three active release lines: 4.23.0.0 just shipped as the latest Regular release, 4.22 continues on LTS maintenance with patch 4.22.1.1, and 4.20 received a maintenance tag (4.20.3.1). A security release (4.22.0.1) in May addressed two CVEs — backup access control and instance access violations. The project's multi-branch support model indicates a large installed base that upgrades slowly.
What is DNSimple?
DNSimple's origin name servers answer a quarter faster at p90 after erldns work
DNSimple keeps tuning the Erlang stack it now runs end to end. The November 4 post says p90 query time on its origin name servers is down about a quarter, and about a third for DNSSEC queries, with roughly a third less CPU, and record changes now switch in one step so existing records never briefly disappear. It follows October's dns_erlang rewrite, which cut CPU per query by 12%, and the August finish of the migration to fully owned infrastructure. Above that layer sit the CLI launched in May, browser login from June, and Domain Trustee.
Apache CloudStack vs DNSimple: editorial side-by-side
Apache CloudStack
5.0INFRA · APIS
Apache CloudStack 4.23 ships as a Regular release while two LTS branches stay on maintenance cadence.
◆ Current state
Apache CloudStack maintains three active release lines: 4.23.0.0 just shipped as the latest Regular release, 4.22 continues on LTS maintenance with patch 4.22.1.1, and 4.20 received a maintenance tag (4.20.3.1). A security release (4.22.0.1) in May addressed two CVEs — backup access control and instance access violations. The project's multi-branch support model indicates a large installed base that upgrades slowly.
◆ Where it's heading
CloudStack follows a predictable Regular → LTS → maintenance cadence. 4.23 as a Regular release means 4.24 or the LTS designation of 4.23 will come next. The concurrent maintenance of 4.20 alongside 4.22 suggests the project serves operators who can't upgrade quickly — a characteristic of infrastructure software running in production cloud deployments. No signal of architectural pivots.
◆ Prediction
A 4.23.x security or maintenance release will follow within 2-3 months, consistent with historical cadence; 4.23 LTS designation or a 4.24 preview could come mid-2027. Security response is active — operators on 4.22 and earlier should apply the CVE patches.
DNSimple

DNSimple's origin name servers answer a quarter faster at p90 after erldns work
◆ Current state
DNSimple keeps tuning the Erlang stack it now runs end to end. The November 4 post says p90 query time on its origin name servers is down about a quarter, and about a third for DNSSEC queries, with roughly a third less CPU, and record changes now switch in one step so existing records never briefly disappear. It follows October's dns_erlang rewrite, which cut CPU per query by 12%, and the August finish of the migration to fully owned infrastructure. Above that layer sit the CLI launched in May, browser login from June, and Domain Trustee.
◆ Where it's heading
Since owning its full DNS edge, DNSimple has turned to measurable performance work on erldns and dns_erlang, published openly. The product layer above, CLI and API clients, is moving more slowly.
◆ Prediction
Expect more erldns and dns_erlang performance posts; the entries show no sign of a new customer-facing product soon.
