CloudShark Support

System Requirements


CloudShark can run on both virtual machine (VM) and bare metal installations. Consider the rest of your infrastructure when choosing your deployment options.

All tiers must have a 64-bit (x86_64) CPU and Gigabit Ethernet (or faster) network connectivity.

  • Minimum
  • Dual-core CPU
  • 8 GB RAM
  • 500 GB free disk space
  • Recommended
  • Quad-core CPU or better
  • ≥ 32 GB RAM
  • 4.0 TB free disk space

Estimated Performance

Because your individual usage of CloudShark is very specific to your organization, and so much depends on the contents of the capture files as well as the number of concurrent users you have accessing CloudShark, we’ve put together the following table to give you an approximate performance level.

  Minimum Recommended
Max File Size Up to 200 MB Up to 4 GB
Number of Users 1-5 25+

Note on maximum capture sizes

Some analysis tools are more intensive on the CPU and disk than others and may take longer depending on the content and size of the capture file. Suggested sizes are estimates only.

Analysis is capped at what can be completed in a reasonable amount of time. To run some tools and filters against larger files, your hardware will need to be powerful enough.

Note that CloudShark’s storage requirements grow linearly with the size of the capture files stored. Many CloudShark deployments use existing SANs within an organization. For local storage, we recommend a redundant storage array and ext4 filesystem with high performance disks.

Trial System-Requirements

CloudShark can be sufficiently evaluated when installed onto a system meeting the minimum requirements. Full production deployment however should be up to the recomended specs.

Operating System

CloudShark runs on a standard 64-bit (x86_64) Linux machine. The following operating systems are currently supported:

All installation types, such as minimal install, full desktop install, etc. are supported. We recommend a minimal install of the latest release and all available security updates. To update the system, run the command yum upgrade.

Please note that Red Hat Enterprise Linux may require the configuration of an optional software channel to fully support all of CloudShark’s dependencies. CloudShark’s installer will generate a warning if this channel is disabled.

The CloudShark OVA

For rapid deployment of CloudShark we’ve also created an OVA image based on CentOS. The CloudShark OVA is a pre-installed Linux system that boots directly into the CloudShark installer. It is the easiest way to get CloudShark running for individuals unfamiliar with Linux.

CloudShark on AWS EC2

CloudShark supports running on any instance type that is Amazon EBS-Backed. For the best performance choose the Compute Optimized C4 instance type. It is also possible to run on the General Purpose T2 instance type, however, this is better suited to trials or single user CloudShark instances.

As Amazon is always improving their offerings, it’s worth checking the list of instance types frequently to see if there are better options available.

Internet Access

Access to the internet is not required to install or run CloudShark. We provide “offline installers” for these situations. It is important to note however, that the server will need access to the original installation media for the operating system. This is usually a DVD.
