There are more than one type of application container technology that can be used by enterprises.
The latest update for Red Hat's RHEL platform with the 8.7 and 9.1 milestone was released this week. New features and capabilities have been added to RHEL 8.7 and 9.1 in order to help organizations use Podman containers more effectively.
IBM bought Red Hat for $34 billion in January of last year.
The flagship Linux platform of Red Hat is Red Hat Enterprise Linux. Multiple versions of Red Hat's enterprise platform are supported by the company.
The first update of Red Hat Enterprise Linux 9 is currently getting a preview and is up to its seventh iteration. Red Hat competes in the Linux market against other vendors, which include SUSE Linux and Ubuntu.
Red Hat Enterprise Linux 8.0 introduced a new, predictable lifecycle. A new minor version and a new major version is produced every six months.
There aren't a lot of differences between the two. He said that RHEL 8 will be fully supported until May 2024 with support that can include new features. Maintenance mode will be in place after that.
There are still differences between the two. The security capability for remote attestation is one of the main differences between the 9.1 and 9.1 milestone.
Administrators can now verify that a remote system's boot environment has not been tampered with. Confirmation that the expected kernels are being called instead of a compromised boot image is included.
The Keylime project is the basis for the remote attestation. Multiple level security is a requirement in some government agencies. MLS can be used to classify components based on the level of confidentiality required.
The modern use of application containers can be traced back to the use of the container technology called "docker". The vendor is named Docker. Red Hat doesn't use container technology in RHEL 8.6 and 9.1.
Over the last several years, Red Hat has continued to develop the open source Podman container technology which it leads, with a number of enhancements now available in preview as part of the RHEL updates.
enterprise users will be able to monitor and check Podman containers for health and availability as part of the RHEL web console. Better visibility for enterprise users can be found in the web console's list ofCPU andmemory utilization.
Podman is almost at the same level of features as Docker. It has a number of feature sets that are not available in the container.
The ability to export code for import into a container configuration is one of the ways that Podman is differentiating itself. There are a lot of containers in the system. Sigstore digital signing and authenticating for supply chain security into Podman will enable the container technology to both sign and verify applications.
Red Hat sees Sigstore as an important part of application development
He said that the IT industry, developers, and even government organizations are very concerned with the concept of a Software Bill of Materials. The adoption of Sigstore by Red Hat has been due to the two initiatives.
