 * **Ideal for big data**: Works well with large amounts of time series data from APM, Kubernetes, IoT sensors, connected cars, industrial telemetry, financial data and various [Enterprise workloads](https://docs.victoriametrics.com/victoriametrics/enterprise/).
 * **Query language**: Supports both PromQL and the more performant MetricsQL.
 * **Easy to setup**: No dependencies, single [small binary](https://medium.com/@valyala/stripping-dependency-bloat-in-victoriametrics-docker-image-983fb5912b0d), configuration through command-line flags, but the default is also fine-tuned; backup and restore with [instant snapshots](https://medium.com/@valyala/how-victoriametrics-makes-instant-snapshots-for-multi-terabyte-time-series-data-e1f3fb0e0282).
-* **Global query view**: Multiple Prometheus instances or any other data sources may ingest data into VictoriaMetrics and be queried via a single query.

+### Scenario
 
-## Overview {#scenario}
+Let's cover the case. You have multiple regions with workloads and want to collect metrics.
 
-This guide shows how to run VictoriaMetrics across many regions in high-availability mode. Each workload runs a local vmagent and sends metrics to dedicated monitoring deployments, so metric data is duplicated and available even if one monitoring region is down.
+The monitoring setup is in the dedicated regions as shown below:
 
-Use this architecture when you need region-level resilience and want monitoring to keep working even if one region becomes unavailable.
+![Multi-regional setup with VictoriaMetrics: Dedicated regions for monitoring](setup.webp)
 
-This setup gives you:
+Every workload region (Earth, Mars, Venus) has a vmagent that sends data to multiple regions with a monitoring setup. 
+The monitoring setup (Ground Control 1,2) contains VictoriaMetrics Time Series Database(TSDB) cluster or single.
 
-* High availability of metric data across regions.
-* A single global query endpoint.
-* Simpler disaster recovery.
+Using this schema, you can achieve:
 
-The trade-off is that you store and send the same data twice, so storage and compute requirements are increased.
-
-## Architecture
-
-The example architecture separates workloads into three regions, called Earth, Mars, and Venus. These represent the systems you want to monitor (e.g., your applications or your infrastructure). For monitoring, there are two separate regions, Ground Control 1 and 2, each running its own VictoriaMetrics deployment. The workload regions (the planets) run a local vmagent that forwards the same metrics to the two dedicated Ground Control regions.
-
-![Multi-regional setup with VictoriaMetrics: Dedicated regions for monitoring](setup-1.webp)
-{width="700"}
-
-The role of the Ground Controls can be filled by VictoriaMetrics in [single-node](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/) or [cluster mode](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/).
-
-## High Availability
-
-The architecture provides high availability by storing two full copies of the data: one in Ground Control 1 and the other in Ground Control 2. Since both store the same data, losing one region doesn't result in a monitoring outage. You can still run queries, view dashboards, and receive alerts.
-
-vmagent keeps a separate persistent queue for each `-remoteWrite.url` destination. If one Ground Control region is unavailable, vmagent continues sending data to the other region. The samples for the unavailable region stay in the file-based queue, and vmagent delivers them after the region recovers. The queue size is limited by disk space available to the vmagent or group of vmagents. This helps restore consistency across both regions.
-
-This setup provides two logical copies of the data in separate monitoring regions. That lets you fail over to the healthy region if one region becomes unavailable, or spread read load across both regions if needed.
+* Global Querying View
+* Querying all metrics from one monitoring installation
+* High Availability
+* You can lose one region, but your experience will be the same.
+* Of course, that means you duplicate your traffic twice.
 
 ### How to write the data to Ground Control regions
 
-Run one or more vmagent nodes in each workload region and configure them to send metrics to both Ground Control regions. This gives each workload region a local write path and keeps delivery going if one monitoring region is unavailable. 
-
-For example, a vmagent that sends data to two single-node VictoriaMetrics instances looks like this:
+* You need to pass two `-remoteWrite.url` command-line options to `vmagent`:
 
 ```sh
 /path/to/vmagent-prod \
-  -remoteWrite.url=https://ground-control-1:8428/api/v1/write \
-  -remoteWrite.url=https://ground-control-2:8428/api/v1/write
+  -remoteWrite.url=<ground-control-1-remote-write> \
+  -remoteWrite.url=<ground-control-2-remote-write>
 ```
 
-For a VictoriaMetrics cluster, use the following URLs for [`accountID=0`](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multitenancy)
+* If you scrape data from Prometheus-compatible targets, then please specify `-promscrape.config` parameter as well.
 
-```sh
-/path/to/vmagent-prod \
-  -remoteWrite.url=https://ground-control-1-vminsert:8480/insert/0/prometheus/api/v1/write \
-  -remoteWrite.url=https://ground-control-2-vminsert:8480/insert/0/prometheus/api/v1/write
-```
-For more details, see [data ingestion with vmagent](https://docs.victoriametrics.com/victoriametrics/data-ingestion/vmagent/).
-vmagent [alerting rules and dashboards](https://docs.victoriametrics.com/vmagent/index.html#monitoring) help to monitor 
-the health state of each configured destination and its queue size.
+Here is a Quickstart guide for [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/#quick-start)
 
 ### How to read the data from Ground Control regions
 
-You can read data from Ground Control regions in a few different ways. The best option depends on your needs and operational complexity:
+You can use one of the following options:
 
-* Choose region via load balancer: put a load balancer in front of both Ground Control regions. Route traffic to a preferred region, with automatic failover to the other region in case of failure.
-* Merge results from multiple regions via vmselect: run a dedicated vmselect that would be configured to read from both regions and merge the results.
+1. Multi-level [vmselect setup](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multi-level-cluster-setup) in cluster setup, top-level vmselect(s) reads data from cluster-level vmselects
+   * Returns data in one of the clusters is unavailable  
+   * Merges data from both sources. You need to turn on [deduplication](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#deduplication) to remove duplicates 
+1. Regional endpoints - use one regional endpoint as default and switch to another if there is an issue.
+1. Load balancer - that sends queries to a particular region. The benefit and disadvantage of this setup is that it's simple.
+1. Promxy - proxy that reads data from multiple Prometheus-like sources. It allows reading data more intelligently to cover the region's unavailability out of the box. It doesn't support MetricsQL yet (please check this issue).
+1. Global vmselect in cluster setup - you can set up an additional subset of vmselects that knows about all storages in all regions.
+   * The [deduplication](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#deduplication) in 1ms on the vmselect side must be turned on. This setup allows you to query data using MetricsQL.
+   * The downside is that vmselect waits for a response from all storages in all regions.
 
-You can read more about choosing the right architecture in the [VictoriaMetrics topologies guide](https://docs.victoriametrics.com/guides/vm-architectures/).
 
-#### Load balancer
+### High Availability
 
-Use a load balancer when you want one stable query endpoint in front of your Ground Control regions. In this setup, dashboards and tools send queries to a single URL, and vmauth routes each request to one available region.
+The data is duplicated twice, and every region contains a full copy of the data. That means one region can be offline.
 
-The following diagram shows [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/) performing the role of [load balancer for HA setups](https://docs.victoriametrics.com/vmauth/index.html#high-availability).
+You don't need to set up a replication factor using the VictoriaMetrics cluster.
 
-![Diagram shows vmauth between Grafana and Ground Control regions](load-balancer-vmauth.webp)
-{width="700"}
+### Alerting
 
-This approach is faster than [merging results with vmselect](#vmselect), because each query goes to only one region. It can also reduce query latency by roughly half compared with a topology that reads and merges data from both regions.
+You can set up vmalert in each Ground control region that evaluates recording and alerting rules. As every region contains a full copy of the data, you don't need to synchronize recording rules from one region to another.
 
-The main downside is that vmauth does not know whether a recovered region has already finished replaying delayed data from the vmagent queue. If you send queries to that region too early, recent data may still be incomplete. In that case, it is better to wait until the region catches up before routing traffic there.
+For alert deduplication, please use [cluster mode in Alertmanager](https://prometheus.io/docs/alerting/latest/alertmanager/#high-availability).
 
-For VictoriaMetrics single node, you can vmauth it with the following configuration:
+We also recommend adopting the list of [alerting rules](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/deployment/docker#alerts)
+for VictoriaMetrics components.
 
-```yaml
-unauthorized_user:
-  url_prefix:
-    - "http://ground-control-1:8428"
-    - "http://ground-control-2:8428"
-  load_balancing_policy: first_available
-```
+### Monitoring
 
-On the VictoriaMetrics cluster, the URLs must point to the Ground Control vmselect nodes. For example:
+An additional VictoriaMetrics single can be set up in every region, scraping metrics from the main TSDB.
 
-```yaml
-unauthorized_user:
-  url_prefix:
-    - "http://ground-control-1-vmselect:8481"
-    - "http://ground-control-2-vmselect:8481"
-  load_balancing_policy: first_available
-```
+You also may evaluate the option to send these metrics to the neighbour region to achieve HA.
 
-The examples above show how to load balance requests without authentication. You can optionally configure authentication in several ways; for more details, read the [vmauth authorization section](https://docs.victoriametrics.com/victoriametrics/vmauth/#authorization).
+Additional context
+* VictoriaMetrics Single - [https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#monitoring](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#monitoring)
+* VictoriaMetrics Cluster - [https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#monitoring](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#monitoring)
 
-To start vmauth with your configuration, use the `-auth.config` flag. For example:
 
-```sh
-/path/to/vmauth-prod -auth.config=/path/to/auth.yaml
-```
-
-You can test that queries work with curl:
-
-```sh
-# single node
-curl http://vmauth-node:8427/api/v1/query?query=up
-
-# cluster
-curl http://vmauth-node:8427/select/0/prometheus/api/v1/query?query=up
-```
-
-For an example of this topology in Kubernetes, see the [`VMDistributed` resource](https://docs.victoriametrics.com/helm/victoriametrics-k8s-stack/#vmdistributed-enabled).
-
-#### vmselect
-
-> This option requires that Ground Control regions are deployed in one of these modes:
-> - As a [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/).
-> - Or as VictoriaMetrics [single-node with multitenant support enabled](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#multi-tenancy). In other words, VictoriaMetrics should be started with the optional `-vmselectAddr=:8401` command line flag to enable the vmselect RPC server.
-
-In this setup, each Ground Control region has its own local vmselect. A top-level vmselect queries these instead of connecting directly to vmstorage nodes.
-
-![Diagram shows top-level vmselect connecting to the regional vmselect nodes in each Ground Control cluster](top-level-vmselect.webp)
-{width="700"}
-
-This option is useful when direct access to vmstorage nodes is not practical or desirable. For example, when running on Kubernetes, the vmstorage services don't provide an HTTP query endpoint by default.
-
-To enable this setup, each Ground Control regional vmselect must listen for requests from the top layer by setting the `-clusternativeListenAddr` flag. The top-level vmselect must then use `-storageNode` to point to the regional vmselect nodes and must set a [deduplication](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#deduplication) interval to handle duplicated data.
-
-For example, here's how we can run the local cluster vmselect nodes and a top-level vmselect node:
-
-```sh
-# Ground Control 1 cluster vmselect
-/path/to/vmselect-prod \
-  -storageNode=ground-control-1-vmstorage-1:8401,ground-control-1-vmstorage-2:8401 \
-  -clusternativeListenAddr=:8401
-
-# Ground Control 2 cluster vmselect
-/path/to/vmselect-prod \
-  -storageNode=ground-control-2-vmstorage-1:8401,ground-control-2-vmstorage-2:8401 \
-  -clusternativeListenAddr=:8401
-
-# Top-level vmselect
-/path/to/vmselect-prod \
-  -storageNode=ground-control-1-vmselect:8401,ground-control-2-vmselect:8401 \
-  -dedup.minScrapeInterval=1ms \
-  -replicationFactor=2
-```
-
-This option provides a single query endpoint for both Ground Control regions. If one region becomes unavailable, the global vmselect can still query the healthy region, so dashboards and queries can continue to work.
-
-The main trade-off is performance. In a two-level vmselect topology, queries pass through two query layers, so they usually take longer than using regional endpoints directly, or through a load balancer. The benefit is that the topology is easy to understand; it keeps working if one region is lost, and it can merge data from both regions while one region is still catching up after recovery.
-
-## Alerting
-
-Run a vmalert node in each Ground Control region and point it to the local VictoriaMetrics endpoint. Since each region stores the same data, you can deploy the same alerting and recording rules in every region without needing cross-region rule synchronization. Send alerts to an [Alertmanager cluster](https://prometheus.io/docs/alerting/latest/alertmanager/#high-availability) to deduplicate firing alerts.
-
-![Diagram showing vmalert nodes running in each Ground Control region. An Alertmanager cluster connects to each vmalert and deduplicates notifications](vmalert-alertmanager.webp)
-{width="700"}
-
-A simple vmalert example for a single-node VictoriaMetrics looks like this:
-
-```sh
-/path/to/vmalert \
-  -rule=/path/to/rules.yaml \
-  -datasource.url=http://ground-control-1:8428 \
-  -notifier.url=http://alertmanager-1:9093 \
-  -notifier.url=http://alertmanager-2:9093
-```
-
-In VictoriaMetrics cluster mode, point `-datasource.url` to the regional vmselect endpoint. For example:
-
-```sh
-/path/to/vmalert \
-  -rule=/path/to/rules.yaml \
-  -datasource.url=http://ground-control-1-vmselect:8481/select/0/prometheus \
-  -notifier.url=http://alertmanager-1:9093,http://alertmanager-2:9093
-```
-
-If you want vmalert to preserve alert state and recording rule results across restarts, configure `-remoteWrite.url` and `-remoteRead.url` to point to VictoriaMetrics as well. For example, for a VictoriaMetrics cluster:
-
-```sh
-/path/to/vmalert \
-  -rule=/path/to/rules.yaml \
-  -datasource.url=http://ground-control-1-vmselect:8481/select/0/prometheus \
-  -remoteRead.url=http://ground-control-1-vmselect:8481/select/0/prometheus \
-  -remoteWrite.url=http://ground-control-1-vminsert:8480/insert/0/prometheus \
-  -notifier.url=http://alertmanager-1:9093,http://alertmanager-2:9093
-```
-
-We recommend using the list of [VictoriaMetrics alerting rules](https://github.com/VictoriaMetrics/VictoriaMetrics/tree/master/deployment/docker#alerts).
-
-## Monitoring
-
-You can monitor Ground Control instances themselves using a separate monitoring path. In this setup, each region runs its own monitoring instance that scrapes metrics from the Ground Control components.
-
-![Diagram of the original setup with monitoring of monitoring added. Each region has a dedicated VictoriaMetrics instance dedicated to monitoring the main TSDB](setup-mom-1.webp)
-{width="700"}
-
-You can optionally duplicate the monitored metrics to the neighboring region for extra resilience. That way, if a whole Ground Control region goes down, you still have access to the telemetry of the downed VictoriaMetrics instance, which can help you troubleshoot and restore service more easily.
-
-Refer to the following pages on how to monitor your VictoriaMetrics deployments:
-
-* [How to monitor VictoriaMetrics single node](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#monitoring)
-* [How to monitor a VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#monitoring)
-
-## What more can we do?
-
-You can deploy extra vmagent instances in Ground Control regions and use them as regional ingestion proxies. This places the write endpoint closer to storage and adds another disk-backed buffer, which improves resilience when storage is temporarily unavailable.
-
-![Diagram of the original setup where a vmagent node runs in front of each Ground Control region](setup-vmagent-1.webp)
-{width="700"}
-
-This pattern is useful when you want more reliable delivery, local relabeling, or a cleaner separation between cross-region traffic and local storage ingestion.
-
-For a Ground Control running VictoriaMetrics single node, you can run vmagent as follows:
-
-```sh
-# vmagent next to Ground Control 1
-/path/to/vmagent-prod \
-  -remoteWrite.url=http://ground-control-1:8428/api/v1/write
-```
-
-If running in cluster mode, use this instead:
-
-```sh
-# vmagent next to Ground Control 1 for cluster mode
-/path/to/vmagent-prod \
-  -remoteWrite.url=http://ground-control-1-vminsert:8480/insert/0/prometheus/api/v1/write
-```
+### What more can we do?
 
+Setup vmagents in Ground Control regions. That allows it to accept data close to storage and add more reliability if storage is temporarily offline.
