OnSite Deployment (OSD) vs Software as a Service (SaaS)

The following highlights the considerations for each option:

NOTE: For security considerations and more detail on how SD Elements is secured, see "How is SD Elements Secured?" article 

OneSite Deployment (OSD):

This option is available only for Enterprise customers.

  • Additional support cost captured in the OSD pricing.
  • Backup and monitoring for security and availability is responsibility of the client's IT.
  • Updates are generally available within a few days after the update for SaaS.
  • Updates need to be applied by the client's admin (as simple as running a single command on the appliance).
  • Due to lack of access, resolving technical issues takes longer compared to SaaS and is usually done over webex.

 

Software as a Service (SaaS) - Dedicated Instance:

This is the default option for all medium and large customers.

  • All customizations available to OSD can be done in SaaS dedicated instances.
  • Provides complete segregation: Each instance has a dedicated server stack: web, application, and database server. The running environments are completely isolated/segregated.
  • Data is backed up hourly and the whole system is backed up daily and stored securely offsite.
  • Data and service restoration can be done in a very short time in case of issues.
  • Firewall and IDS protected and all security activities are monitored by our trained staff according to industry best practices.
  • Monitoring available for application errors.
  • SSO available via SAML Federated authentication. LDAP is normally not possible since corporate LDAP servers are typically not available from the outside network.
  • Theming and other customization available.

 

Software as a Service (SaaS) - Shared Instance:

This option is used for Demo, Proof-of-Concept (PoC), and small clients only.

  • All considerations of SaaS Dedicated Instances are applicable here except for data segregation.
  • Data is segregated at application level. Each organization will have its own completely isolated space/sandbox.
  • Theming and SSO are NOT available.
  • Localization such as changing the titles Business Unit, Application, and Project to custom strings are NOT available.
  • Custom Pluggable Reports are NOT support.
  • Unless otherwise specified, other basic features such as API are available similar to other options.
