This topic describes some common connectivity design scenarios using Megaport <Gloss term="Ports" anchor="port" />, <Gloss term="Megaport Cloud Router (MCR)" anchor="mcr" />, and <Gloss term="Megaport Virtual Edge (MVE)" anchor="mve" />. The scenarios range from a simple partially-protected network to an end-to-end highly available resilient network for <Gloss term="multicloud" anchor="multicloud" /> and hybrid cloud.

For more information about different multicloud scenarios and defining your connectivity requirements, see the [Design Scenarios for Multicloud -- Diversity and Design Principles blog](https://www.megaport.com/blog/design-scenarios-for-multicloud/). You can also download our Multicloud Network Blueprints Infopaper at [Multicloud Network Blueprints](https://www.megaport.com/pdf/megaport_multicloud_blueprints.pdf).

<Tip>
  To help you architect your multicloud solution, you can [download a Visio (VSDX) file](https://go.megaport.com/multicloud-vsdx-download.html) with these scenarios.
