Development of Red Hat Enterprise Linux

Red Hat develops and integrates open source software into Red Hat Enterprise Linux through a multistage process.
  • We participate in supporting individual open source projects. We contribute code, developer time, resources, and other support, often collaborating with developers from other Linux distributions. This helps to improve the general quality of software for all of us.
  • We sponsor and integrate open source projects into a community-driven Linux distribution, Fedora. Fedora provides a free working environment that can serve as a development lab and proving ground for features that may be incorporated into our commercially-supported products.
  • We stabilize the software to ensure that it's ready for long term support and standardization, and integrate it into our enterprise-ready distribution, Red Hat Enterprise Linux.

Fedora

Fedora is a community project that produces and releases a complete, free Linux-based operating system. Red Hat sponsors the community and works with community representatives to integrate the latest upstream software into a fast-moving and secure distribution. The Fedora project contributes everything back to the free and open source world, and anyone can participate.
However, Fedora is focused on innovation and excellence, not long-term stability. New major updates happen every six months, and they can bring significant changes. Fedora only supports releases for about a year (two major updates). This can make Fedora less suitable for enterprise use.

Red Hat Enterprise Linux

Red Hat Enterprise Linux is Red Hat's enterprise-ready, commercially supported Linux distribution. The leading platform for open source computing, it's not just a collection of mature open source projects. Red Hat Enterprise Linux is extensively tested, with a large supporting ecosystem of partners, hardware and software certifications, consulting services, training, and multi-year support and maintenance guarantees.
Red Hat bases its major releases of Red Hat Enterprise Linux on Fedora. But after that, Red Hat can pick and choose which packages to include, make further enhancements (contributed back to the upstream projects and Fedora), and make configuration decisions that serve the needs of customers. Red Hat helps vendors and customers engage with the open source community, to work with upstream development to develop solutions and fix issues.
Red Hat Enterprise Linux is provided through a subscription-based model. Since this is open source software, this isn't a license fee. Instead, it pays for support, maintenance, updates, security patches, access to the knowledgebase on the Red Hat Customer Portal, certifications, and so on. The customer is paying for long-term support and expertise, commitment, and assistance when they need it.
When major updates become available, customers can move to them at their convenience without paying more. This can simplify management of both the economic and practical aspects of system updates.

Trying Out Red Hat Enterprise Linux

There are a number of different ways to try Red Hat Enterprise Linux. One is to download an evaluation copy from the Red Hat website. A number of links to supplementary information are also available on that page.
Red Hat also makes available free subscriptions of a number of our products for development purposes through the Red Hat Developer Program. These subscriptions allow developers to easily develop, prototype, test, and demonstrate their software on the same enterprise products that it will eventually be deployed with.
Another approach is to deploy an instance of Red Hat Enterprise Linux made available through a cloud provider. For example, in this course the hands-on labs are designed to use an official Red Hat Enterprise Linux image provided through a major cloud provider's image catalog.

Special Permissions in linux

The setuid permission on an executable file means that the command will run as the user owning the file, not as the user that ran the command. One example is the passwd command: [student@desktopX ~]$ ls -l /usr/bin/passwd -rw s r-xr-x. 1 root root 35504 Jul 16 2010 /usr/bin/passwd In a long listing, you can spot the setuid permissions by a lowercase s where you would normally expect the x (owner execute permissions) to be. If the owner does not have execute permissions, this will be replaced by an uppercase S . The special permission setgid on a directory means that files created in the directory will inherit their group ownership from the directory, rather than inheriting it from the creating user. This is commonly used on group collaborative directories to automatically change a file from the default private group to the shared group, or if files in a directory should be

The Seven-Step Model of Migration

Irrespective of the migration approach adopted, the Seven-step Model of Cloud Migration creates a more rational point of view towards the migration process and offers the ability to imbibe several best practices throughout the journey Step 1: Assess Cloud migration assessments are conducted to understand the complexities in the migration process at the code, design and architectural levels. The investment and the recurring costs are also evaluated along with gauging the tools, test cases, functionalities and other features related to the configuration. Step 2: Isolate The applications to be migrated to the cloud from the internal data center are freed of dependencies pertaining to the environment and the existing system. This step cuts a clearer picture about the complexity of the migration process. Step 3: Map Most organisations hold a detailed mapping of their environment with all the systems and applications. This information can be used to distinguish between the
