* all services run on the same machine, and they will compete for resources. This includes any compute jobs.
* it uses the local machine disk for Keep storage (under the @/tmp@ directory). There may not be a lot of space available.
-* it installs the @crunch-dispatch-local@ dispatcher, which can run just eight concurrent CWL jobs. These jobs will be executed on the same machine that runs all the Arvados services and may well starve them of resources.

It is possible to start with the single host installation method and modify the Arvados configuration file later to address these limitations. E.g. switch to a "different storage volume setup":{{site.baseurl}}/install/configure-s3-object-storage.html for Keep, and switch to "the cloud dispatcher":{{site.baseurl}}/install/crunch2-cloud/install-dispatch-cloud.html to provision compute resources dynamically.
Edit the variables in the <i>local.params</i> file. Pay attention to the <notextile><b>*_PORT, *_TOKEN</b> and <b>*_KEY</b></notextile> variables. The *SSL_MODE* variable is discussed in the next section.
