![]() ![]() Option 3: Send Data to the Splunk Cloud via a Heavy Forwarderįinally, data can be sent to a heavy forwarder (HF) before going to Splunk Cloud. Overall, this option is more scalable than the first, but requires more hardware and coordination. If such a thing is not allowed, there will need to be IFs in every datacenter where there are UFs, and planning must happen to send data to the correct IF. Another consideration with this plan is data transmission between data centers. You can also send heavy forwarder data through these IFs, though that will increase network load due to the increased size of parsed data. With this approach, only the IFs will need special firewall rules maintained for them. The main benefit of this architecture is to minimize firewall holes. IFs use the same software as UFs, so they are very lightweight and perform minimal processing. It is highly recommended to have at least two IFs to prevent a single point of failure (Splunk can load balance between IFs without a dedicated load balancer). The intermediate forwarder will need to be on its own server in order to have the resources for processing large amounts of data. The second option is to send data to an intermediate forwarder before sending to Splunk Cloud. Option 2: Send data to the Splunk Cloud via an Intermediate Forwarder The cut off for when this option is viable will depend on the customer, but in general this set up is best for small environments. With a small environment, this ask is easy to implement and maintain, but once the environment scales up, there can be thousands of firewall rules to maintain. ![]() Firewall rules will need to be mended in order to allow outbound traffic from source hosts. Problems emerge when considering the connection between the source hosts and Splunk Cloud. UFs are installed on every source host and are configured with the environment-specific Splunk Cloud Forwarding app (downloadable from every Splunk Cloud Web UI). This approach doesn’t require any additional hardware (unless a deployment server is used) and has no single point of failure. The first and simplest option is to send data directly from source hosts to Splunk Cloud via a UF. Option 1: Send Data to the Splunk Cloud via a Universal Forwarder These strategies also aren’t mutually exclusive they can be mixed and matched depending on individual circumstances. Each of these methods has pros and cons that will be covered here, so anyone moving to Splunk Cloud can make a decision on how they will forward data. Splunk Stream App, which usually is mandatory for whatever data will use it), there are 3 options for forwarding data: directly via universal forwarder (UF), indirectly via intermediate forwarder (IF), or directly via a heavy forwarder (HF). Besides the niche forwarding methods (i.e. One of the big questions a team must answer is, “How will data be sent from devices like workstations and domain controllers to Splunk Cloud?” But that is more complicated than it may seem. ![]() Implementing Splunk Cloud prompts teams to make many decisions about their environment, from hardware specs to compliance standards.
