2. Remote Access Server

Remote Access is the ability to get access to a computer or a network from
a remote distance. A Remote Access Server is the computer and
associated software that is set up to handle users seeking access to
network remotely.

A Remote Access Server usually includes or is associated with a firewall
server to ensure security and a router that can forward the remote access
request to another part of the corporate network.

A remote access server could be hosted on a multi-tenant cloud so that a
small group of different organizations Remote Access Users can share the
common pool of RAS and its routers.

A remote access server may also be used as part of a virtual private
network (VPN) or a Cloud connecting with Service Providers cloud.

6. Multi Tenancy Architecture Basics

Multi-tenancy is an architecture in which a single instance of a software
application serves multiple customers. Each customer is called a tenant.
Tenants may be given the ability to customize some parts of the
application.

Multi-tenancy can be economical because software, hardware and
maintenance costs are shared. It can be contrasted with single-tenancy,
an architecture in which each customer has their own software instance
and may be given access to limited Network and applications.

A software-as-a-service (SaaS) provider, for example, can run one instance
of its application on one instance of a database and provide web access
to multiple customers. In such a scenario, each tenant's data is isolated
and remains invisible to other tenants.
