Is etcd or Site24x7 better?

Neither clearly leads. etcd starts at On request and Site24x7 at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.

Which is cheaper, etcd or Site24x7?

Site24x7 has a free tier; the other does not. Paid plans start at On request for etcd and Free for Site24x7.

Does etcd or Site24x7 run on more platforms?

Both run on Web, so platform support will not decide this one for you.

Can I use Site24x7 for free?

Yes. Site24x7 has a free tier, so you can try it without paying. etcd starts at On request.

What is etcd best used for?

etcd is most often used for storing kubernetes cluster state, which is what the overwhelming majority of etcd deployments are doing, leader election and distributed locking in a home-grown scheduler or control plane, using leases and transactions, service discovery and dynamic configuration where readers need to be notified of changes rather than poll for them, coordinating failover in a clustered database, as patroni does for postgresql. Of those, storing kubernetes cluster state, which is what the overwhelming majority of etcd deployments are doing and leader election and distributed locking in a home-grown scheduler or control plane, using leases and transactions are not what Site24x7 is typically brought in for.

What can etcd do that Site24x7 cannot?

etcd covers Raft consensus, Linearizable reads, Transactions, Leases.

The short version

Only Site24x7 has a free tier, so it costs nothing to try first.
Each has a real cost: etcd it is sized for coordination data, not application data: the default backend quota is 2 GB and 8 GB is the documented recommended maximum, and exceeding it puts the cluster into a NOSPACE alarm where it accepts no writes until an operator compacts, defragments and clears the alarm by hand.; Site24x7 website and infrastructure monitoring are sold as separate plan tracks; the entry Web Uptime plan ($9/month annual) covers only 25 websites and does not include server monitoring, which requires a separate Lite infrastructure plan

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

etcd

It is sized for coordination data, not application data: the default backend quota is 2 GB and 8 GB is the documented recommended maximum, and exceeding it puts the cluster into a NOSPACE alarm where it accepts no writes until an operator compacts, defragments and clears the alarm by hand.
Every write is replicated and fsynced before acknowledgement, so cluster performance is bounded by the slowest disk in it; a member on network-attached storage with high fsync latency causes leader elections and cluster-wide latency spikes that look like network problems and are not.
Adding members increases availability but reduces write throughput, because each write must reach a larger quorum; you run three or five members for fault tolerance, and increasing capacity means faster hardware rather than more nodes.
There is no sharding and no multi-tenancy, so isolating workloads means running separate clusters, each with its own quorum, certificates, backup schedule and upgrade path, and that operational multiplication is often unexpected.
Running it yourself is a real job: periodic compaction and defragmentation, snapshot backups you have actually rehearsed restoring, and rotation of both peer and client TLS certificates, none of which happens automatically outside a managed Kubernetes service.
Losing quorum is not self-healing; recovering a cluster that has lost a majority means restoring from a snapshot and accepting that everything written since that snapshot is gone, which makes backup frequency a data-loss budget decision rather than a routine setting.

Site24x7

Website and infrastructure monitoring are sold as separate plan tracks; the entry Web Uptime plan ($9/month annual) covers only 25 websites and does not include server monitoring, which requires a separate Lite infrastructure plan
Entry infrastructure Lite plan covers only 2 servers and 25 child resources before requiring an upgrade to Professional
The discounted monthly-equivalent prices shown (e.g. $9/month for Web Uptime) require annual prepayment; standard monthly billing is priced higher (e.g. $10/month)
Enterprise tier pricing starts at $625/month and Enterprise Plus Web at $899/month, both paid annually

Answered from the vendors’ own pages

etcd: Can I use etcd as an application database?

No. It is designed for metadata and coordination, with a recommended maximum store size of around 8 GB, no sharding and a write path deliberately optimised for durability rather than throughput. Application data belongs in a database built for it.

Site24x7: How much does Site24x7 cost?

Site24x7 pricing starts at $9 per month for web monitoring (25 websites) with annual billing, or $10 per month with monthly billing. Enterprise plans scale to $899 per month for website monitoring and $625 per month for infrastructure monitoring.

Source

etcd: How many members should a cluster have?

Three for most cases, five where you need to survive two simultaneous failures. Always an odd number, because an even-sized cluster gains no additional fault tolerance while making quorum harder to reach.

Site24x7: Does Site24x7 offer a free tier?

Yes, Site24x7 offers a free forever plan allowing users to monitor the uptime of up to 50 resources with instant downtime email alerts. Higher plans provide monitoring for hundreds or thousands of resources with advanced features.

Source

etcd: What happens when the store fills up?

The cluster raises a NOSPACE alarm and stops accepting writes, becoming effectively read-only. Recovery requires compacting old revisions, defragmenting each member and then explicitly disarming the alarm, all done by an operator.

Site24x7: What add-ons are available for Site24x7?

Site24x7 offers modular add-ons including uptime monitors ($18-$140/month), log ingestion ($3-$12 per 10GB monthly), RUM page views ($25-$300/month), and cloud monitoring (starting at $1/resource/month). Pricing varies based on usage and plan tier.

Source

etcd: Why is my etcd cluster slow or unstable?

Almost always disk latency. Because every write is fsynced before acknowledgement, slow or shared storage causes heartbeat timeouts, leader elections and cascading latency. Local SSDs with low fsync latency are effectively a requirement.

etcd: How does it compare with Consul or ZooKeeper?

All three provide consensus-backed coordination. etcd has the simplest data model and the Kubernetes ecosystem behind it; Consul bundles service discovery, health checking and a service mesh; ZooKeeper is older, JVM-based and still common under Kafka and Hadoop-era systems.
