Note that:

  • hardware requirements depend on various factors related to the Application(s) you are analyzing and these must be considered:
    • Number of lines of code (LOC)
    • Number of objects after analysis
    • Number of violations after analysis
    • Technologies used
    • Number of users accessing results
  • due to the different factors that need to be considered, it is difficult to make precise hardware recommendations, therefore what we provide in this page is indicative only. We provide these figures as a guide to the absolute minimum required to run AIP Console and all required components, and your own configuration will likely require better hardware.
  • using storage/disk with high IOPS values (i.e. SSD disks or SANs configured with SSD) will bring better performance. This is particularly true for servers hosting the CAST AIP/AIP Node and CAST Storage Service/PostgreSQL components where faster storage will improve analysis performance.
  • installations of CAST AIP on servers with resources that are lower than the minimum required or that barely meet the minimum requirements will have the following limitations:
    • analysis runtime and SQL operations will be sub-optimal
    • you cannot run more than one application in parallel
    • disk space can be quickly overloaded

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 .

It is possible to re-use one of the existing servers dedicated to the CAST RESTAPI or CAST AIP/AIP Node, providing that this is a Windows server, however CAST does recommend a dedicated server where possible.

Single server (Small/Testing)

Although it is possible to run all required packages and components from one single Windows server, CAST does not recommend this approach for "production" environments.

8GB 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.

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.

To ensure good performance during analysis, we advise, for each application, a memory range between 8 GB RAM (for small applications) and 32 GB RAM (for very large applications). Therefore, to analyze up to 50 applications and to run up to 5 analyses in parallel on one single AIP Node with one associated CAST Storage Service/PostgreSQL instance, CAST recommends increasing RAM and DISK resources as follows:

DISK

AIP Core + AIP Node (back end)

48GB min / 128GB recommended

You can distribute your applications across multiple CAST Storage Service/PostgreSQL instances, as discussed in Which deployment architecture should you use?

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.

For JEE, it does not include Security for Java extension, which has specific RAM requirements.
