  • CAST Imaging is a CPU and RAM intensive application and for that reason, CAST recommends using a dedicated server (physical or virtual) specifically for CAST Imaging. In other words CAST does not recommend installing any other service (whether CAST or third-party) on the same server as CAST Imaging.
  • The installation on Microsoft Windows (non-Docker) will be blocked on machines configured with less than 8GB.
  • For Docker deployments on Microsoft Windows, a minimum of 16GB RAM must be allocated to Docker Desktop.

These items are all provided as Linux based Docker images in the public Docker Hub (.JAR file installs are also provided, however, these are targeted at deployments on Microsoft Windows on one single machine (including the AIP Node and the PostgreSQL instance) i.e. for demo or POC requirements).

Disk space

The recommended disk space takes into account space for the following folders hosted on the AIP Node:

  • Delivery folder
  • Deploy folder
  • Log files,
  • Extensions folder
  • LISA / LTSA

You can refer to Deployment considerations for CAST Imaging for more information about this.

Windows

16GB RAM is the absolute minimum requirement to allow all packages and components to function, however, analysis performance will be poor as the available resources will be shared between the AIP Node and the CAST Storage Service and investigation performance in CAST Imaging may also be compromised.

Example on-premises hardware configuration

Managing multiple applications

If you are managing a large number of applications, we recommend installing multiple AIP Nodes, one node per server to spread the load. The disk space allocated to a single AIP Node obviously depends on the size and the number of applications that will be analyzed by the AIP Node. In a situation where all the AIP Nodes are running analyses, some AIP Nodes may need to run more than one analysis in parallel. To avoid overloading the AIP Node where more than one analysis is running at the same time, we strongly recommend deploying servers with sufficient resources.

Therefore, to analyze up to 50 applications and to run up to 5 analysis in parallel on one single AIP Node with one associated PostgreSQL instance, CAST recommends increasing RAM and DISK resources as follows:

ComponentRAMDISK
AIP Core + AIP Node (back end)32GB min2TB (SSD recommended)
PostgreSQL64GB min3TB (SSD recommended)

Analyzing complex applications

While 90% of JEE, .NET or Mainframe applications can be analyzed with the minimum requirements, some specific (very large or not well balanced) applications require more memory than the minimum recommendations. The following configurations are examples of sizing required for very large applications. The requirements are not a linear function that are based purely on the number of files or lines of code (LoC), instead it is more complex and there is no specific formula to use.

In general, a lack of memory will cause slowness (servers will resort to the use of virtual space) in the best case, and a crash in the worst case. The numbers presented in the table below are purely indicative and depict the varying memory requirements.
