Many businesses today are delivering applications to users as an on-demand
service. This reduces the cost of application management and can improve
application and data security. Citrix® XenApp™ empowers companies to
achieve these results as well as other benefits. Challenges do however remain
around maintaining application availability and protecting the integrity of
your data. This white paper explores what availability really means, and
how availability correlates to RTO and RPO baselines. The concept of levels
of availability is introduced, which is an industry analyst driven definition
for multiple levels of availability used to protect different applications from
downtime to fulfill SLA commitments. XenApp and XenApp infrastructure
components are analyzed to determine how they can be protected so you can
achieve your SLA commitments. Marathon Technologies everRun® software
is introduced with XenApp deployment samples depicting how everRun can
be used to protect XenApp from downtime and data loss.
