The Single Server Deployment topology is typically used for smaller, non-business critical use-cases that are often departmental in nature. It provides a very simple, cost effective solution if your environment meets all of the following criteria:

• You do not have any requirements to provide high availability or automated disaster recovery for your Splunk software deployment.
• Your daily data ingest is less than approximately 500 GB.
• You have a small number of users with non-critical search use cases.

The primary benefits of this topology include the following:

• Simple administration, performant search for smaller data volumes, and a fixed total cost of ownership (TCO).
• Multiple independent single-instance deployments can be managed by a single management tier.
• Straightforward migration path to a distributed deployment.

The primary limitations of this topology include the following:

• No high availability for search or indexing.
• Scalability limited by hardware capacity.
