This enables you to send the metrics from multiple Prometheus servers to a single Cortex cluster and run "globally aggregated" queries across all data in a single place. 21 - **Highly available:** When run in a cluster, Cortex can replicate data between machines. This allows you to survive machine failure without gaps in your graphs. 22 - **Multi-tenant:** Cortex can isolate data and queries from multiple different independent 23 Prometheus sources in a single cluster, allowing untrusted parties to share the same cluster. 24 - **Long term storage:** Cortex supports S3, GCS, Swift and Microsoft Azure for long term storage of metric data. This allows you to durably store data for longer than the lifetime of any single machine, and use this data for long term capacity planning. 25 26 Cortex is a [CNCF](https://cncf.io) incubation project used in several production systems including [Weave Cloud](https://cloud.weave.works) and [Grafana Cloud](https://grafana.com/cloud). 27 Cortex is primarily used as a [remote write](https://prometheus.io/docs/operating/configuration/#remote_write) destination for Prometheus, exposing a Prometheus-compatible query API. 28 29 ## Documentation 30 31 Read the [getting started guide](getting-started/_index.md) if you're new to the 32 project. Before deploying Cortex with a permanent storage backend you 33 should read: 34 35 1. [An overview of Cortex's architecture](architecture.md) 36 1. [Getting started with Cortex](getting-started/_index.md) 37 1. [Information regarding configuring Cortex](configuration/_index.md) 38 39 There are also individual [guides](guides/_index.md) to many tasks. 40 Please review the important [security advice](guides/security.md) before deploying. 41 42 For a guide to contributing to Cortex, see the [contributor guidelines](contributing/). 43 44 ## Further reading 45 46 To learn more about Cortex, consult the following talks and articles. 47 48 ### Recent talks and articles 49 50 - Dec 2020 blog post "[How AWS and Grafana Labs are scaling Cortex for the

132 ## <a name="help"></a>Getting Help 133 134 If you have any questions about Cortex: 135 136 - Ask a question on the [Cortex Slack channel](https://cloud-native.slack.com/messages/cortex/). To invite yourself to the CNCF Slack, visit http://slack.cncf.io/. 137 - <a href="https://github.com/cortexproject/cortex/issues/new">File an issue.</a> 138 - Send an email to <a href="mailto:cortex-users@lists.cncf.io">cortex-users@lists.cncf.io</a> 139 140 Your feedback is always welcome. 141 142 ## Hosted Cortex (Prometheus as a service) 143 144 There are several commercial services where you can use Cortex 145 on-demand: 146 147 ### Weave Cloud 148 149 [Weave Cloud](https://cloud.weave.works) from 150 [Weaveworks](https://weave.works) lets you deploy, manage, and monitor 151 container-based applications. Sign up at https://cloud.weave.works 152 and follow the instructions there. Additional help can also be found 153 in the [Weave Cloud documentation](https://www.weave.works/docs/cloud/latest/overview/). 154 155 [Instrumenting Your App: Best Practices](https://www.weave.works/docs/cloud/latest/tasks/monitor/best-instrumenting/) 156 157 ### Grafana Cloud 158 159 The Cortex project was started by Tom Wilkie (Grafana Labs' VP Product) and Julius Volz (Prometheus' co-founder) in June 2016. Employing 6 out of 8 maintainers for Cortex enables [Grafana Labs](https://grafana.com/) to offer Cortex-as-a-service with exceptional performance and reliability. As the creators of [Grafana](https://grafana.com/oss/grafana/), [Loki](https://grafana.com/oss/loki/), and [Tempo](https://grafana.com/oss/tempo/), Grafana Labs can offer you the most wholistic Observability-as-a-Service stack out there. 160 161 For further information see Grafana Cloud [documentation](https://grafana.com/docs/grafana-cloud/), [tutorials](https://grafana.com/tutorials/), [webinars](https://grafana.com/videos/), and [KubeCon talks](https://grafana.com/categories/cortex/). Get started today and [sign up here](https://grafana.com/products/cloud/). 162 163 ### Amazon Managed Service for Prometheus (AMP) 164 [Amazon Managed Service for Prometheus (AMP)](https://aws.amazon.com/prometheus/) is a Prometheus-compatible monitoring service that makes it easy to monitor containerized applications at scale. It is a highly available, secure, and managed monitoring for your containers. Get started [here](https://console.aws.amazon.com/prometheus/home). To learn more about the AMP, reference our [documentation](https://docs.aws.amazon.com/prometheus/latest/userguide/what-is-Amazon-Managed-Service-Prometheus.html) and [Getting Started with AMP blog](https://aws.amazon.com/blogs/mt/getting-started-amazon-managed-service-for-prometheus/). 165 166
