+Pulsar is a multi-tenant, high-performance solution for server-to-server messaging. Pulsar was originally developed by [Yahoo](http://yahoo.github.io/), it is under the stewardship of the [Apache Software Foundation](https://www.apache.org/).
-Pulsar's key features include:
+Key features of Pulsar are listed below:
-* Native support for multiple clusters in a Pulsar instance, with seamless [geo-replication](administration-geo.md) of messages across clusters
-* Very low publish and end-to-end latency
-* Seamless scalability out to over a million topics
-* A simple [client API](concepts-clients.md) with bindings for [Java](client-libraries-java.md), [Go](client-libraries-go.md), [Python](client-libraries-python.md) and [C++](client-libraries-cpp.md)
-* Multiple [subscription modes](concepts-messaging.md#subscription-modes) for topics ([exclusive](concepts-messaging.md#exclusive), [shared](concepts-messaging.md#shared), and [failover](concepts-messaging.md#failover))
-* Guaranteed message delivery with [persistent message storage](concepts-architecture-overview.md#persistent-storage) provided by [Apache BookKeeper](http://bookkeeper.apache.org/)
-* A serverless lightweight computing framework [Pulsar Functions](functions-overview.md) offers stream native data processing.
-* A serverless connector framework [Pulsar IO](io-overview.md) built on-top-of Pulsar Functions to make moving data in and out Apache Pulsar easier.

+* A serverless connector framework [Pulsar IO](io-overview.md), which is built on Pulsar Functions, makes it easier to move data in and out Apache Pulsar.
* [Tiered Storage](concepts-tiered-storage.md) offloads data from hot/warm storage to cold/longterm storage (such as S3 and GCS) when the data is aging out.
