Aruba Networks is a product that is broadly available and there are many implementation partners available to design and implement the infrastructure for you. Aruba Networks is great if you are looking for a partner that offers a broad range of devices. It can keep a multi-location infrastructure simple once the management interface is set up. Aruba is less appropriate if you want to do a simple setup with a few devices where you want to be up and running quickly. The management interface can be a hassle to set up and if you want Azure integration you are better off contacting an implementation partner that has dealt with this before.
Aruba Networks Wireless WAN stacks really well against its other competitors for its features, ease of implementation, and administration. The pricing is very competitive with great vendor support and excellent documentation. The centralized management feature is really good as it provides a single pane of glass for all administrative items.
